This document discusses different types of agriculture practiced around the world. It begins by explaining how agriculture originated as nomadic pastoralism before the development of sedentary farming. Nomadic pastoralism remains an important form of agriculture in many developing regions. The document then categorizes agriculture as either subsistence or commercial and practiced in developing or developed countries. It provides examples of different agricultural practices in different world regions, including nomadic pastoralism, transhumance, shifting cultivation, plantations, and various crop and livestock systems. The prevalence of different agricultural types varies globally depending on environmental and cultural factors.
Von thunen’s model of agricultural land useThe Urban Unit
This presentation is based on a agricultural land use model around the city. This is the theory of urban Geography it describe the agricultural pattern and how should the agricultural activities perform around the city. basically this Model was put forwarded before industrialization and when there was no roads networks and this Model is not applicable in real word but is gives great ideas for developing new towns and cities.
DETERMINANTS OF AGRICULTURE (INSTITUTIONAL AND TECHNOLOGICAL FACTOR)Calcutta University
Institutional and technological factors are important determinants of Indian agriculture. Key institutional factors include land tenure systems established by the British, small landholding sizes due to inheritance practices, and land reforms aimed at redistributing land from large to small owners. Technological factors that have influenced agriculture include the introduction of high-yielding seed varieties, expansion of irrigation through canals and groundwater, increased use of fertilizers and pesticides, and greater mechanization through tractors and farm machinery. While these changes have increased agricultural productivity and output, many small farmers still lack access to technology.
This document provides an overview of the course GETh 405: Agricultural Geography. It discusses key concepts in agricultural geography including the definition and scope of the subject, agricultural systems and how they are influenced by physical, socio-economic and technological factors. It also outlines various models used in agriculture and approaches to classifying and regionalizing agricultural patterns worldwide. The document lists several recommended readings and resources on topics like the agriculture of Bangladesh, diffusion of innovations, and agricultural systems around the world.
Settlement geography is a branch of human geography that deals with how human populations are distributed on Earth and how settlements form and change over time. It examines characteristics like population size, layout, functions, and relationship to the surrounding environment. Originally focused on describing existing settlement patterns, the field has evolved to use remote sensing and modeling to analyze changes and plan more sustainable development. Settlement geography considers factors influencing where and how people first formed settlements and how they have expanded, as well as issues around rapid urbanization and strategies for improving rural and urban livability. While its scope has adapted over time, the core focus remains understanding the physical attributes of settlements and their interactions with social and environmental conditions.
Geography is an interesting subject for all. It deals with location, space, patterns and distribution of life, landforms, resources, environment and development. Human geography is the study of human use and understanding of the whole world and the processes which have affected it. This module explains about the importance of human geography.
This document provides an overview of agriculture and farming practices in India. It discusses the types of farming (primitive subsistence, intensive subsistence, commercial), major crops grown (rice, wheat, millets, pulses, sugarcane, oilseeds, tea, coffee), and cropping patterns (rabi, kharif, zaid). It also describes India's public distribution system and buffer stocks which aim to ensure national food security by making food grains available at subsidized prices.
This document outlines several approaches to agricultural geography:
1. The empirical (inductive) approach attempts to describe existing agricultural patterns by making generalizations based on numerous studies.
2. The normative (deductive) approach leads to the derivation and testing of hypotheses to develop ideal models of agricultural location.
3. Other approaches discussed include the environmental, commodity, economic, regional, systematic, system analysis, ecological, and behavioral approaches. Each looks at agricultural activities through a different analytical lens.

Geographical factors affecting agricultural sector and service sectorSaloni Sanghani
Geographical factors influence both the agricultural and service sectors. For agriculture, natural factors like climate, soil, and topography determine what crops can be grown and how productive the land will be. Economic factors such as market access, transportation, labor availability and capital investment also shape the type of farming practiced. Social and political systems further impact agriculture through policies, land ownership structures, and subsidies. For services, key geographical factors include the availability of raw materials, power, labor, transportation, access to markets, water, suitable land, and supportive climate conditions which determine where industries can successfully locate and operate.
Von thunen theory of agricultural land useWESLEY MELI
Von Thunen's model of agricultural land use proposes that the type of agriculture in concentric zones around a central market city is determined by the transportation costs of different agricultural products. The model suggests that dairy farming and intensive agriculture will occur in the innermost zone due to high transportation costs for perishable products. Timber and firewood production is next as wood is heavy. Extensive grain farming is in the third zone as grains have lower transport costs. Ranching is in the outermost zone as livestock are self-transporting and have the lowest transport costs. The model aims to explain the balance between land costs and transportation in determining agricultural location patterns.
There are 10 major cultural realms in the world according to H. Robinson's classification system. These include the Polar region, European region, Anglo-American region, Latin American region, Dry region, African region, Oriental region, and Australia-New Zealand region. Each cultural realm is characterized by shared linguistic, religious, and other cultural traits as well as similarities in climate, occupation, and level of development.

Industrial geography is the study of manufacturing industries and how they are influenced by and influence geographic factors like location. There are several approaches to studying industrial geography, including behavioral, Marxist, radical, capitalist, and industrial location approaches. Some major factors that influence industrial location are availability of raw materials, access to markets, available labor supply, transportation infrastructure, water and energy resources, and government policies. In Bangladesh, some of the most important factors shaping industrialization are abundant low-cost labor supply, access to raw materials like tea plants, transportation via roads, rivers and rail, and availability of water and energy resources like hydroelectric power from rivers.
The economy of the world is fast changing during the recent years.
The changes in primary, secondary and tertiary stages are dynamic in nature.
In view of this, the objectives of studying economic geography are to integrate several factors of economic development to acquaint with the dynamic aspects of the Scenario. This module is about basics of economic geography.
The primary aim of studying settlement geography is to acquaint with the spatial and structural characteristics of human settlements under varied environmental conditions.
Population geography is the study of human population distribution and dynamics across different regions. It examines how numbers, characteristics, and movement of people vary based on environmental and cultural factors in an area. G.T. Trewartha is considered the father of population geography for establishing it as a distinct subfield in the 1950s and proposing what topics it encompasses. Population geography analyzes absolute population sizes, qualities like age and sex ratios, and dynamics including fertility, mortality, and migration patterns. It also relates population trends to variables like resources, development levels, and government policies. As an interdisciplinary field, it interconnects with demography, sociology, economics, history and other social sciences.
This document discusses the differences between systematic and regional geography. Systematic geography studies one geographic topic or phenomenon globally, such as climatology or soils. Regional geography analyzes all geographic aspects of a particular place or region. While these were initially seen as separate approaches, geographers now recognize them as interconnected and complementary. The regional provides real-world examples and data to test theories from systematic geography, while systematic studies form rules and laws that can be applied to different regions. Together, they provide a more comprehensive understanding of geography.
The document discusses the concept of paradigms in geography. It defines a paradigm as a set of beliefs and assumptions that shape how one views reality in a particular field. It notes that major paradigm shifts have occurred in geography, such as Ptolemy's geocentric model being replaced by Copernicus' heliocentric model. The document outlines several paradigms that have influenced geography, such as the romantic analytical paradigm of early geographers like Ritter and Humboldt, and the political geography paradigm associated with the rise of nation states. It also mentions that geography currently lacks complete revolutions and paradigms shifts, but different schools of thought are seeking new paradigms to better understand geographical regions.
This notes about Introduction to Economic Geography. Which helped to Geography & Environmental Science department students.
In this note I will discourse about:
1) The concept of Economic Geography
2) Historical Vs Modern economic geography
Economic activity can be classified into five sectors:
1) The primary sector involves extraction of natural resources and includes activities like agriculture, fishing, mining and forestry. It dominates in underdeveloped countries.
2) The secondary sector transforms raw materials into goods through manufacturing and industry. It contributes moderately to national income in developed countries.
3) The tertiary sector provides services to consumers and businesses. It accounts for most employment in developed countries.
4) The quaternary sector is knowledge-based and includes information technology, research and development, and knowledge services.
5) The quinary sector involves the highest levels of decision making in government, science, and other major institutions.
Origin of culture :Cultural hearth and cultural realm, cultural region.RAJKUMARPOREL
The document discusses the origin and development of cultural hearths and cultural regions around the world. It identifies the seven original cultural hearths as Mesopotamia, the Nile River Valley, the Aegean region, the Indus River Valley, the Ganges River Valley, the Wei-Huang Valley, and West Africa. These early hearths developed around major river systems and influenced the spread of culture. The document also outlines the major cultural realms of Occidental, Islamic, Indian, East Asian, and minor realms of Southeast Asia and Sub-Saharan Africa. It defines key terms like cultural area and cultural boundary.
There are two main ways to map population distribution: showing where individuals are located or plotting population density by area. Population density maps the relationship between population numbers and land area using a choropleth method showing people per square kilometer. However, choropleth maps have limitations as they use average densities that can conceal variations within areas and give a sudden impression of changes between neighboring units. For example, Japan's average density understates concentrations in habitable lowlands. Physical, climatic, environmental and socioeconomic factors all influence why some areas have low or high population densities.
Human geography is the study of the relationship between humans and the Earth's surface. It examines how humans interact with the environment and each other in various spatial contexts. The document outlines different perspectives on this relationship, including environmental determinism, possibilism, and neo-determinism. It also discusses fields within human geography like social, cultural, economic, and urban geography and how they relate to other social sciences.
Von Thunen published his theory of agricultural land use patterns in 1826 in his book "The Isolated State". The theory was based on an isolated region with homogeneous climate and soil quality where the only mode of transportation was by foot. It proposed that there would be concentric zones of land use radiating from the city center based on transport costs and product perishability. Dairy farming would be in the innermost zone due to high transport costs of perishable products, followed by zones for forestry, vegetables, and grazing further from the city. The bid rent curve showed the relationship between economic rent and distance from the market. While pioneering, the theory was based on unrealistic assumptions and had limitations in applying to contemporary systems

The document discusses key concepts in population geography, including population density, distribution, growth rates, and population structures. It provides data on population statistics globally and for various countries and regions. Maps show the distribution and concentration of populations worldwide, and in countries like the United States and China. Charts illustrate population growth and changing growth rates over time.
The quantitative revolution in geography began in the 1950s with Schaefer's critique of the traditional regional geography approach. Schaefer argued geography should seek general patterns and laws across regions using quantitative methods rather than focusing on unique regions. This sparked a major transformation in the field toward spatial analysis and modeling using statistics, mathematics, and later computers. By the 1960s, the "new geography" focused on rigorous theory testing and had largely replaced the older descriptive regional approach. However, criticisms emerged in the 1970s that quantitative methods dehumanized geography and were unable to fully explain human spatial patterns. This led to the rise of qualitative approaches. While quantitative geography declined, it resurged in the 1990s with new spatial analysis techniques
This document discusses key concepts in population geography, including population density, distribution, growth rates, and concentrations around the world. It provides data on population statistics for various countries and regions. Some of the major topics covered include the distribution of the world's population; areas of high and low density in countries like the US, China, Bangladesh; population growth rates; and factors affecting birth and death rates in different parts of the world. Maps and diagrams are presented to illustrate global and regional population patterns.
Vietnam's agriculture is dominated by rice cultivation. The North has 15% of Vietnam's arable land concentrated in the Red River Delta, allowing for 2-3 rice crops per year through irrigation. The South's main rice growing region is the Mekong Delta, with single-cropping and irrigation supporting year-round cultivation. Other key crops include coffee, tea, pepper, rubber, and cassava, which are important industrial and export products. Collectivization of agriculture occurred earlier in the North beginning in 1956, while the South began collectivization later in 1978 as part of five-year economic plans.

This document discusses Jane McGonigal's work on using game design principles and elements of games to address real-world issues. It summarizes some of McGonigal's key ideas from her book Reality is Broken, including that games provide intrinsic rewards like satisfaction and social connection instead of just extrinsic rewards. It also discusses how concepts like flow and failure can create positive feelings in games and how multiplayer online games can foster collaboration. The document poses questions about the reader's own game playing and suggests games, apps, and systems that apply gaming to improve real-life activities and problems.
The document discusses the state of global agriculture and its effects on ecosystems. It notes that 15 of 24 key ecosystem services have been degraded or unsustainably used in recent decades due largely to expansion of agriculture. About half of original forests have been lost to agriculture. Agriculture appropriates one third of the planet's net primary productivity and is a major driver of biodiversity loss and carbon emissions. Feeding a growing population while reducing these impacts will require intensifying production on existing farmland and improving sustainability through techniques like irrigation, fertilization, and conservation agriculture.
- The document discusses rainfed agriculture in the Near East and North Africa region, where around 80% of arable land is rainfed.
- Smallholder rainfed farming systems face numerous constraints including drought, poor soils, low input use, small farm sizes, and lack of infrastructure/market access.
- Climate change is exacerbating problems with more variable rainfall and more frequent droughts and floods.
- There is significant untapped potential to improve productivity and incomes in rainfed areas through strategies like sustainable land management, improved soils, suitable cropping systems, and water management.
Agricultural Transformation and Rural Developmentguestf494e5
The document discusses agricultural development and rural transformation. It covers several topics:
1) More than half the world's population lives in rural areas facing poverty, inequality, unemployment and rapid population growth. Integrated rural development strategies are needed to address these issues.
2) Agriculture employs most of the labor force in developing countries but accounts for a small portion of GDP. Agricultural productivity has increased in some countries but declined in others like Africa.
3) Agrarian systems and agricultural development stages vary around the world. Recommended policies include improving small farmer productivity, rural non-farm employment, and equitable access to technology and credit.
This document provides an overview of plantation agriculture and oil palm plantations in Malaysia. It describes the key characteristics of plantation agriculture, including large land sizes and commercial single crop production. The document then discusses the historical development and current ownership structures of plantations. It also outlines the distribution, importance and challenges of oil palm plantations in Malaysia, the largest global producer, including their processes from cultivation to processing.

1. Progressive technologies play a significant role in achieving water savings, better irrigation operation and maintenance, and gains in food production. Technologies can be categorized as off-farm, on-farm, and soft tools.
2. Off-farm technologies include canal lining, piped conveyance, flow measurement devices, and supervisory control systems. On-farm technologies include surface irrigation improvements, sprinklers, micro-irrigation, reservoirs, and drainage.
3. Soft tools include simulation models, benchmarking, remote sensing, and decision support systems to improve irrigation management, monitoring, and evaluation.
The document discusses different types of agriculture including shifting cultivation, wet rice cultivation, plantation agriculture, and high-tech farming. Shifting cultivation involves clearing small plots of land and farming them until the soil becomes infertile, then moving to another plot. Wet rice cultivation is practiced in Asia and involves growing rice in flooded terraced fields. Plantation agriculture grows cash crops like oil palm on large estates. High-tech farming uses advanced technology like hydroponics, aeroponics, computers and machinery.
Six sigma is a statistical approach to process improvement that aims to reduce defects. It was developed by Motorola in the 1970s to improve quality. The six sigma method includes phases such as Define, Measure, Analyze, Improve, and Control to identify and remove defects in processes. It uses statistical tools and follows a DMAIC or DMADV model. While six sigma aims to improve processes and reduce defects, some critics argue it is more focused on appraisal than prevention and does not always yield quality improvements.
This document discusses different types of agricultural practices around the world. It contrasts subsistence agriculture, which is aimed at producing only enough food for a farmer's family, with commercial agriculture which produces surpluses for sale. Subsistence agriculture is more common in less developed countries and involves small family farms, while commercial agriculture with larger farms is more prevalent in developed nations. The document also examines different forms of subsistence agriculture including intensive farming, shifting cultivation, and pastoral nomadism.

Farming involves cultivating crops and rearing animals to produce food and other goods. A farm can be viewed as a system with inputs, processes, outputs, and feedback. Inputs include physical resources like land, water, and raw materials as well as human inputs such as labor and skills. Processes are actions like milking, harvesting, and shearing that transform inputs into outputs. Outputs are the finished products as well as any profits from sales, while feedback puts resources back into the system through money and knowledge gained. Farms can be categorized based on the type of farming, land size, and techniques used.
This document summarizes animal husbandry practices around the world. It discusses how different animals like cattle, poultry, pigs, sheep, horses and others are raised domestically for purposes like food, fiber, work and pleasure. Modern industrial farming focuses on intensive, large-scale and efficient production, while traditional systems are usually smaller-scale and lower-yielding. Husbandry techniques vary significantly between regions and cultures based on the local uses and needs for each animal.
The document discusses the history and development of agriculture. It begins by explaining the four economic sectors and provides examples of sector sizes in different countries. It then covers the transition from hunter-gatherers to the Neolithic Revolution and agricultural developments like seed planting, irrigation, and the Columbian Exchange. The document also discusses the First, Second, and Third Agricultural Revolutions and innovations like the Green Revolution. Finally, it examines different types of farming like subsistence, commercial, and plantation as well as rural land use patterns.

Getting Food
Cultural Anthropology
Food-getting activities take precedence over all other survival needs, including reproduction, social control, defense, and transmission of knowledge to the next generation
Cultural Anthropology
In our society food-getting strategies are simplified – we merely need to go to the supermarket

"'Freegans' Take Green to Extreme"
Cultural Anthropology
But for some of the world, the level of food-getting takes up more time and is much more labor-intensive. It is called subsistence economics.
Cultural Anthropology
Subsistence economics is a situation where basically all able-bodied adults are engaged in getting food for themselves and their family as their main activity
Cultural Anthropology
Subsistence economics is how humans obtained their food for millions of years by foraging for their subsistence – e.g. gathering plants, nuts, berries, scavenging, hunting and fishing
Cultural Anthropology
Foraging is much less common today
As a subsistence style, it is used today by hunter-gatherers, who make up only about 5 million people on the planet
Cultural Anthropology
Foraging for plant life – gathering plants, berries, seeds, nuts and tubers is more common in areas close to the equator as compared to northern latitudes such as the Arctic, where plant life is scarce
Video:
"Hunter-Gatherers"
Cultural Anthropology
In northern climates, since plants are scarce, hunting is more predominant
See an Inuit (Eskimo) hunter in Northern Canada in the classic anthropological film “ “Nanook of the North” (1922)
Foragers
Foragers actually spend less time obtaining food than most other types of food-getters
!Kung adults of Southern Africa spend just 17 hours a week on average getting food
Characteristics of Foragers
Foragers generally have small communities with no class differences
Getting Food: General Features of Food Collectors
A survey of 180 food-collecting societies indicates that there is a lot of variation with regard to which food-getting activity is most important to the society. Gathering is the most important activity for 30 percent of the surveyed societies, hunting for 25 percent, and fishing for 38 percent.
*
Food Production
Most of the world does not forage for food but produces it in one fashion or another
3 types of food production; horticulture, pastoralism, and intensive agriculture
No food production strategy is perfect, as the videos illustrate
Video:
'Women’s Horticulture Group in Burkina Faso"
Food Production
Horticulturalists have relatively small plots of land
Often use hand tools instead of machines
May also raise small animals; pigs, chickens, sheep, goats
Getting Food: Food Production
Horticulture
Plant cultivation carried out with relatively simple tools and methods; nature is allowed to replace nutrients in the soil, in the absence of permanently cultivated fields
Main Horticultural Method - Shifting cultivation

The document discusses different types of agricultural activities. It defines agriculture and describes primary activities like farming, fishing, and mining. Secondary activities involve manufacturing goods from natural resources, like steel production. Tertiary activities provide support services to primary and secondary sectors, such as transportation and banking. The document also discusses different types of farming like subsistence, commercial, plantation, and dairy farming, and provides examples of major crops grown worldwide.
The document discusses different types of agricultural activities. It classifies activities into three sectors: primary, secondary, and tertiary. Primary activities include extraction of natural resources like agriculture, fishing, and mining. Secondary activities involve manufacturing goods from natural resources, such as steel production. Tertiary activities provide support services to the other sectors, including transportation, trade, banking, and advertising. The document then focuses on defining and providing examples of agriculture, the different types of farming (subsistence, commercial, plantation), and major crops grown around the world like rice, wheat, cotton, coffee, and tea.
This document provides an overview of agriculture. It discusses how agriculture began around 10,000 years ago through the deliberate cultivation of plants and domestication of animals. It contrasts hunting and gathering societies with agricultural societies. The document then covers the origins of vegetative and seed-based agriculture in different regions. It discusses the differences between subsistence and commercial agriculture. It also maps the global distribution of major agricultural regions and how they correlate with climate zones. Finally, it discusses tools for identifying and protecting productive farmland from urban expansion.
The document discusses different types of activities in the primary sector of the economy, which includes agriculture, livestock farming, fishing, and forestry. It provides details on various forms of agriculture including subsistence, commercial, plantation, and intensive/extensive systems. Livestock is also summarized, distinguishing traditional, commercial extensive and intensive animal husbandry. The primary sector makes up over 30% of the world's workforce but varies significantly between developed and developing countries.
Subsistence farming is often practiced in rural areas of developing countries where access to modern technology and infrastructure is limited. It is typically characterized by small-scale farming, low productivity, and a reliance on traditional farming methods. The crops grown in subsistence farming systems are often a mix of staple crops such as rice, maize, and wheat, as well as vegetables and fruits.
This document defines and describes various types of agriculture. It begins by explaining how nomadic humans settled and began growing crops, establishing the origins of agriculture. Key types of agriculture discussed include subsistence farming, where farmers focus on growing enough food for their families; intensive cultivation, using high amounts of labor, capital and technology; and extensive cultivation, utilizing large areas of land with low labor and capital inputs. The document also outlines plantation farming, organic farming, mixed farming, truck farming, dairy farming, and cooperative farming. Each type is concisely defined.
The document provides an overview of how human subsistence strategies have evolved from hunting and gathering to agriculture and eventually industrialization. It describes key transitions such as the development of horticulture around 10,000 years ago in areas like the Fertile Crescent, which involved the cultivation of plants. This allowed for more sedentary lifestyles and population growth. Further agricultural intensification led to the rise of civilizations, social stratification, and urban centers supported by surrounding agricultural populations. The document contrasts preindustrial and industrial societies in their use of energy and relationship to the environment.
This document discusses strategies for ensuring food security in Ethiopia. It argues that Ethiopia's overdependence on cereals like teff has led to a vicious cycle of low productivity, poverty, and environmental degradation. It proposes diversifying crop production to include potatoes and cassava, which have higher yields and are better suited to Ethiopia's varied climate zones. The document also stresses the need to expand Ethiopians' food habits beyond a narrow range of cereal-based diets to incorporate more nutritious crops. With policy changes and a commitment to more sustainable and diverse agricultural systems, it asserts that Ethiopia can become self-sufficient in food and end its image as a country synonymous with hunger.
The document discusses different classifications of agriculture including subsistence and commercial farming, arable and pastoral farming, dairy farming, market gardening, extensive and intensive farming, shifting and sedentary farming. It provides examples like rice farming in Asia, wheat farming, sheep farming, and discusses inputs, processes, and outputs of different agricultural systems.
The document discusses periodic famines that occur in Niger due to regional failures in food production or distribution systems. It describes Niger's geography and climate, with the northern half being part of the Sahara desert and the central and southern regions receiving more rainfall. Farming practices vary by region, from nomadic herding in the north to agro-pastoral systems and permanent villages in the central and south. The 2005 famine in Niger is examined, caused by below average rainfall and locust plagues that reduced crop yields, combined with poverty, high food prices, and depleted government food reserves. Short term responses included food aid while long term solutions focused on irrigation, dams, wells, and agricultural development.
This document discusses several types of agriculture including primitive, subsistence, commercial, plantation, nomadic, shifting, mixed, and genetic engineering agriculture. Primitive agriculture involves slash and burn techniques with low productivity. Subsistence and shifting agriculture focus on growing just enough for family consumption. Commercial, plantation and mixed agriculture are practiced on a larger scale for profit. Genetic engineering can increase yields and nutrition. Nomadic groups move according to seasonal patterns.
The document provides an overview of agriculture and its origins. It discusses that agriculture began as hunter-gatherer societies around 10,000 years ago and transitioned to the deliberate cultivation of plants and domestication of animals through two main types - vegetative planting and seed agriculture. This first agricultural revolution occurred in multiple hearths around the world, including Southeast Asia, Southwest Asia, Mexico, and Peru. The document then contrasts commercial agriculture practices in developed countries with subsistence agriculture in developing nations.
Agriculture is the cultivation of plants and animals for human sustenance and economic gain. It involves intentional planting and raising of crops and livestock. Agriculture originated independently in different locations as hunter-gatherer societies transitioned to farming. Early forms included vegetative planting and seed agriculture. Major agricultural revolutions improved farming techniques and increased yields. While subsistence farming remains important in developing countries, commercial agriculture dominates in industrialized nations through large-scale, mechanized practices tied to other businesses.

All humans depend on agriculture for food and urbanised,
industrialised societies depend on food surplus generated by
farmers. We could say that without agriculture there could be no
civilisation.
3. Antoine Vella 3
Agriculture is the principal enterprise of
humankind through most of recorded history.
Today it remains the most important economic
activity in the world employs 45 % of the working
population.
This figure varies from 3% in
some European countries to
over 80 % of the labour force in
parts of Africa and Asia.
4. Antoine Vella 4
There are innumerable types of
agriculture practised around the
world. In most regions one can find
different forms existing together but
there are predominant types in
certain parts of the world.

We shall now look at the various types of agriculture as
practised in today’s world. First of all we may divide the
world regions into:
• Developing
• Developed
18. Antoine Vella 18
Basically this is when the farmer (or the local farming
community) produces in order to satisfy their own material
need with little
or no surplus
so that there is
limited external
commerce.
19. Antoine Vella 19
Farmer do not produce all that they need but grow “cash
crops” or other products which are sold, sometimes to
buyers long distances away. The farmer is thus more
integrated within the modern market economy.
This is usually a more
specialised form of
agriculture and found
especially in developed
countries.
20. Antoine Vella 20
In developing regions agriculture may be:
• Nomadic
• Sedentary
Most of farming in
developing countries is
of subsistence type but
we may also find some
traditional examples of
commercial agriculture.
21. Antoine Vella 21
This is a form of agriculture and lifestyle that is gradually
disappearing but can still be found in many areas around
the world.
There are two main
forms here:
• Nomadic pastoralism
• Shifting agriculture
22. Antoine Vella 22
This is an relatively intensive form of field cultivation. It
may be based on rice or other crops
23. Antoine Vella 23
In developing countries there is
only one type of such agriculture
that is widespread:
• Plantations
24. Antoine Vella 24
In developed countries agriculture is typically commercial
and divided into
• Crop husbandry
• Animal husbandry
• Mixed farming
There are also other
special types (e.g.
Mediterranean) which
will be treated later.
25. Antoine Vella 25
Farmers work fields, often using extensive mechanisation
to produce plants for the market.
26. Antoine Vella 26
In this case the farm income comes from the production
and sale of animal products.
27. Antoine Vella 27
This is usually
a traditional
form of
agriculture
based on
smallholdings
and family
farms.

Subsistence may be further
subdivided into:
nomadic or sedentary.

Herding is the practice of
bringing individual animals
together into a group (herd or
flock) and rearing them as a
group. It was the first form of
‘agriculture’ developed by
humans and preceded arable
farming (that is, the growing
of plants).
34. Antoine Vella 34
The first herders were nomads
because their animals depended
exclusively on grazing and the
herds had to be moved in order to
allow the pastures to recover.
Above: Sahel Below: Lapland Right: Tibet
35. Antoine Vella 35
Nomads move from place to place, rather than settling down
in one location. Today there are about 30-40 million worldwide.
Nomads in
northern India
36. Antoine Vella 36
At some point of their history, most cultures have passed
through such a phase and, for some this is still a tradition.
There are three kinds of nomads:
• hunter-gatherers,
• pastoral nomads,
• peripatetic nomads* (gypsies)
* Normally not
engaged in agriculture
38. Antoine Vella 38
Nomadic hunter-gatherers have by far the longest-lived
subsistence method in human history, following seasonally
available wild plants and game.
Bushmen of
Northeast Namibia.
39. Antoine Vella 39
Pastoralists raise herds
and move with them so as
not to deplete pasture
beyond recovery in any one
area. The term ‘Nomadic
Herding’ refers to these
cultures.
40. Antoine Vella 40
Nomads in Sub-Saharan Africa are the only
ones who depend mainly on cattle.
Further north, dromedaries, sheep and goats
are more important. nomads depend on
dromedaries, sheep and goats.
41. Antoine Vella 41
Nomads living in the tundras of northern
Eurasia raise reindeer while those of
central Asia keep camels, horses, yak,
and sheep. In W. Asia nomads depend
on dromedaries, sheep and goats.

family in the Bayan Gobi, Outer Mongolia.

These nomadic cattle-herders use camels as draught
animals.
46. Antoine Vella 46
Nomadic herders rear cattle, sheep, goats, horses and
camels. Some migrate from lowlands in winter to mountains
in summer. Others shift from desert areas in winter to
adjacent semiarid plains in summer

Sahara and Sahel.
Government

48. Antoine Vella 48
As we’ll see later in Shifting Cultivation, Nomadic Herding
also risks becoming unsustainable in many areas.
As animals and
human populations
increase,
overgrazing and
deforestation
intensify with
desertification the
end result.

55. Antoine Vella 55
Many nomads continue to follow age-old traditions and travel along
ancient routes. These were often established long ago, before modern
states were formed and nomads often find their way blocked by national
borders. This creates a problem for them and, sometimes for the various
countries through which they travel.
The shaded area is the ancestral territory
of the Tuareg, now spanning 6 countries
56. Antoine Vella 56
The territories inhabited by ethnic groups often do not
correspond to the national frontiers which have developed
over time.
Since the Middle Ages, the
place Mongols originated
has been divided various
times. At present, the
southern half is part of China
while the northern section is
an independent State.
57. Antoine Vella 57
Today, nomadic herding is
almost everywhere in decline.
Governments have policies
encouraging nomads to become
sedentary.
This process was started in the
19th century by British and
French colonial administrators
in North Africa and later
adopted by Russia in its Asian
territories.
58. Antoine Vella 58
In the Middle East, many nomads are voluntarily abandoning
traditional life to seek jobs in urban areas or oil fields.
Severe droughts in
Sub-Saharan Africa
has caused many to
abandon nomadism
59. Antoine Vella 59
Today, nomadism survives mainly in remote areas, and
may soon completely vanish.
60. Antoine Vella 60
This is a form of pastoralism traditionally organized around
the migration of livestock between mountain pastures in
summer and
descend to
relatively warm
areas in the valleys,
foothills or plains in
winter.
61. Antoine Vella 61
Sometimes the seasonal migration may between lower and
upper latitudes (as in the movement of Siberian reindeer
between the subarctic taiga and the Arctic tundra) is also
known by this name.
Only herds, and the
herders necessary to
tend them, travel with
the herds.
64. Antoine Vella 64
Although, in this section, we’re considering developing
countries, transhumance can also be found in certain
Transhumance of sheep in the
Dolomites (Belluno)
regions of developed
countries.
For the sake of
convenience sake
we’ll describe this
type of farming here.
65. Antoine Vella 65
Traditional transhumance,
occurs throughout the world,
including European
mountainous regions (Alps,
Scandinavia, Balkans, Italy)
as well as India and parts of
Africa.
66. Antoine Vella 66
In Europe this type of agriculture is typical of the
Mediterranean, Balkan and Scandinavian highland regions.
67. Antoine Vella 67
The annual spring Transhumance Festival in Provence. The festival
commemorates the annual migration of flocks to different pastures,
and over 3,000 sheep are herded through the streets.
73. Antoine Vella 73
Transhumance is based on a climate difference between
mountains (where herds stay during summer) and lowlands
(where they remain in winter). Its importance to pastoralist
societies cannot be overstated.
74. Antoine Vella 74
Milk, butter and cheese — dairy products of transhumance
— often form a basis for a local population's diet.
75. Antoine Vella 75
The Sami (aka Lapps) live in northern Norway, Sweden and Finland, with
some groups also found in the Russian Kola peninsula.
76. Antoine Vella 76
Reindeer husbandry has been,
and is, an important aspect of
Sámi culture in Northern
Scandinavia.
77. Antoine Vella 77
During the years of forced assimilation, (esp. in the USSR)
the areas in which reindeer herding was an important
livelihood were among the few where the Sámi culture and
language survived.

This is essentially a land rotation system. Instead or
rotating crops, the land itself is rotated. Probably arose
from a nomadic lifestyle.
Practised especially in less developed parts of the
tropical world where nature can quickly re-establish its
balance and recover from damage.
• Central and S. America
• Africa
• Southeast Asia
• Indonesia
82. Antoine Vella 82
Small patches of land are cleared by chopping vegetation
and girdling trees. When the vegetation has dried, it is
burned.
This technique gives shifting
agriculture the common name
“slash-and-burn”.
Afterwards, using digging
sticks or hoes, farmers plant a
variety of crops in the
clearings.
85. Antoine Vella 85
In an ideal case, shifting cultivation would be a cycle where
farmers came back to the original place after a couple of
years. The picture shows a newly prepared land (known as
swidden) in the centre.
86. Antoine Vella 86
In the background is untouched forest, while the piece of land in
the foreground has been left idle from the previous cropping
cycle to re-grow into a secondary forest. On the right secondary
growth awaiting cultivation during the next cropping cycle.
87. Antoine Vella 87
This “slash-and’burn” plot is in the Ruwenzoris (Mountains of
the Moon). A burgeoning population does not permit a
suitable fallow period; crop yields are poor and the forest
never recovers.
88. Antoine Vella 88
Shifting cultivation by too many people is responsible for
tropical rainforest destruction over a vast area. Intercropping
is practiced with bananas, taro, cassava, beans and sorghum
being planted in the same field.
89. Antoine Vella 89
Shifting agriculture, as practised in tropical areas, has a
harmful effect on the soil. In these areas there is an
excess of precipitation over evaporation, resulting in a
net downward movement of moisture through the soil.
Soil nutrients are
leached from the
soil, leaving
behind an acidic
and infertile soil
that is often
reddish in colour.
90. Antoine Vella 90
Why slash-and-burn farming is no longer sustainable
Improved health conditions have caused population growth
beyond the size supportable by this kind of farming
Swidden fields in Vietnam reaching up to
the top of the hills
As people pass to the
second stage of
demographic
transformation the
periods during which
land is allowed to
remain fallow have
shortened and
environmental
deterioration is caused.
91. Antoine Vella 91
Nature protection which respects traditional culture of ethnic
communities tends to replace the shifting farming systems by
permanent, often tree-based agro-forestry schemes.
It must by all means
be prevented that the
swidden fields
extend to the upper
ridges of the hills as
their the forest cover
is vital to retain
ecosystem functions
and services.
92. Antoine Vella 92
Shifting cultivation is also
carried out in some parts of
Germany but mostly by
amateur farmers who cultivate
land as a hobby.
In this case it is not a slash-
and-burn type of farming. In
Germany, most forest areas
are protected anyway.

Humans need carbohydrates as an essential nutrient and all over the
world these are provided by starch produced by plants.
In some regions,
starch is provided
by potatoes or
other crops but for
the most part,
cereals are the
mainstay of
human life all over
the world.
98. Antoine Vella 98
This is a method of farming in which farmers plan to grow
only enough food to feed the family farming, pay taxes or
feudal dues, and perhaps provide a small marketable
surplus.
The Basotho people
rely on subsistence
agriculture for survival.
Animals raised by
Lesotho farmers include
cattle, donkeys,
chickens, pigs, dogs,
and sheep.
99. Antoine Vella 99
Subsistence agriculture usually refers to a farm that
produces enough to feed the family but not enough surplus
to participate extensively in the cash market.
100. Antoine Vella 100
The typical subsistence farm
has the range of crops and
animals needed by the family
to eat during the year.
Planting decisions are made
according to what the family
will need during the coming
year, rather than market
prices.
101. Antoine Vella 101
It is practised worldwide and represents the first stages of
sedentary agriculture.
It may be primitive and simple
or more advanced but the
principle is always that almost
everything needed is
produced in the immediate
vicinity of the farm.
102. Antoine Vella 102
Subsistence agriculture
(predominantly growing
wheat and barley) first
emerged during the
Neolithic era when
humans started to settle
in the Nile, Euphrates,
and Indus River Valleys.
Subsistence horticulture
(growing vegetables)
may have developed
earlier in South East
Asia and Papua New
Guinea.

It was the dominant mode of production in the the world
until very recently when market-based capitalism became
important.

by the beginning of
World War I, and in
North America during
the 1930s and 1940s.
104. Antoine Vella 104
Subsistence farming continues today in large parts of the
African interior and other areas of Asia and South America.

Subsistence agriculture was sustainable for millennia in the
absence of a population explosion.
Rural Fijians still practice
subsistence agriculture.
Some live in traditional
huts with woven mat
walls and thatched roofs.
Village life is communal,
with everyone expected
to share in ceremonial
preparations and village
upkeep.
107. Antoine Vella 107
Nowadays it is still practised
in a highland region more or
less equivalent to the old Inca
territories.
This region includes some of
South America's poorest
areas.
The farmers who carry out
this type of farming face
considerable environmental
challenges.
108. Antoine Vella 108
Subsistence agriculture
on small farm plots is
practiced in the highly
elevated Altiplano of,
Ecuador, Peru, Bolivia
and northern Chile.
Farmers in the arid highlands must cope with the variable weather
conditions and extreme climatic uncertainty.
109. Antoine Vella 109
The economy in the Nepal
hills depends on subsistence
farming.
Peasants go to the southern
plains and India seeking
porter jobs for 4-8 months
each year to supplement their
incomes.
110. Antoine Vella 110
The money earned from non-
agricultural jobs is exchanged
with consumer goods e.g. salt
or sugar, or even a watch such
one of the farmers in the
picture is wearing. The oxen
available are too few for the
number of farm holdings. The
Monsoon-dependent farming
requires all fields to be
prepared almost all together -
not to own a pair of oxen
possibly means the farmer has
to find sources of energy.

This forms the basis of “plant
civilisations” of Asia — almost all caloric
intake is of plant (mostly rice) origin.
115. Antoine Vella 115
A paddy field is a flooded field used for growing rice. Rice can
also be grown in dry-fields, but from the 20th century, paddy
field agriculture became the dominant form of cultivation.
Paddy fields are a
typical feature of rice-
growing countries of
East and Southeast
Asia but are also
found in other rice-
growing regions such
as Piedmont (Italy),
and the Camargue
(France).
Rice paddies in Bali
116. Antoine Vella 116
Rice is probably the most important grain
with regards to human nutrition and caloric
intake, providing more than 20% of the
calories consumed worldwide by humans.
117. Antoine Vella 117
Tiny, mud-dyked, flooded
rice fields, many perched
on terraced hillsides.
Paddies must be drained and rebuilt each
year. It requires much skill and experience
not only to build the paddies themselves
but also to regulate the water supply.
118. Antoine Vella 118
Rice does not need to grow in water throughout its entire cycle
but only in the first phase of its life.
119. Antoine Vella 119
The role of water is only to protect the young plants from rapid
temperature changes.

121. Antoine Vella 121
The water buffalo is the
only draught animal
adapted for life in wetlands
and is extensively used in
paddies in most of S.E.
Asia.

122. Antoine Vella 122
This animal is
essential to the
survival of

farmers in Asian

123. Antoine Vella 123
The buffalo is used mostly as a work
animal both in agriculture and
transport.

Bottom right: Philippines
124. Antoine Vella 124
The buffalo lives in close contact with humans and is often considered as
a member of the family.
Above: Vietnam Right: India
125. Antoine Vella 125
Water buffaloes have been largely replaced by machinery
especially in Korea and Japan. This type of highly organised
and mechanised agriculture can no longer be described as
subsistence but is a more commercial form of cash cropping.
(see later sections for discussion of commercial farming)
127. Antoine Vella 127
Most paddy rice farms outside the communist area of Asia are small. Small
patches are intensively tilled and large amounts of manure used.
Young rice sprouts are carefully transplanted by hand from seed beds to
paddy. The same parcel of land may be planted 2-3 times a year and yields
are very high – comparable to western ones.
128. Antoine Vella 128
There are significant adverse impacts from rice paddy
cultivation due to the generation of large quantities of methane
which is a greenhouse gas.
129. Antoine Vella 129
Rice is also grown in the Mediterranean, especially in the
Lombardy plain of N. Italy and, to a much less degree in the
Rhone delta in S.France.
Paddy fields in the
Camargue, Rhone delta
In Europe, rice-
growing is not
subsistence
farming and will
be considered
later in the
presentation.
130. Antoine Vella 130
Italy is the largest rice producer and exporter in the EU,
producing 70% of European rice.

132. Antoine Vella 132
World methane production due to rice paddies has been estimated in
the range of 50 - 100 million tonnes yearly; this level of greenhouse gas
generation is a large component of the global warming threat and
derives simply from an expanding human population.
133. Antoine Vella 133
Genetic engineering has been carried out on rice in
Switzerland and Germany to produce a fortified food for
areas where there is a shortage of vitamin A.
134. Antoine Vella 134
In 2005 a new variety called
Golden Rice 2 was announced
which produces up to 23 times
more Vit A than the original golden
rice.
Neither variety is currently
available for human consumption.

135. Antoine Vella 135
Although it was developed as a humanitarian tool, GM rice
has met with significant opposition from environmental and
anti-globalisation activists.

A plantation is usually a large estate, especially in a tropical or
semitropical country, on which cash crops (especially tree or
bush crops) such as cacao, tea, coffee, sugar cane, banana
Coffee plantation in
Honduras
and rubber are
cultivated, usually by
workers who live on
the site itself.
Crops are grown for
sale in distant
markets, rather than
for local
consumption.
140. Antoine Vella 140
The plantation system:
• Relies on large amounts of hand labour
• Originated in the 1400s on Portuguese-owned
islands of the coast of tropical West Africa
• Today, the greatest concentration is in the American
tropics.
• Most plantations lie on or near sea-coasts and
shipping lanes.
• Produce is carried to non-tropical lands — Europe,
United States and Japan.
141. Antoine Vella 141
A plantation is always a monoculture over a large area and,
because of its large size, takes advantage of economies of scale.
142. Antoine Vella 142
Most plantation workers live on the
plantation.
In the past slaves were relied on to
provide the labour
Because of the necessary capital
investment, corporations or
governments are usually owners
of plantations.
144. Antoine Vella 144
The main crops grown in plantations include:
Cacao
Coffee
Tea
Sugar cane
Rubber
Banana
Oil palm
(Date palm)
We will describe them in another part of the course
145. Antoine Vella 145
It should be noted that temperate
fruit crops, such as these cherry
orchards in Japan, are not
considered plantations in the
classical sense.
146. Antoine Vella 146
Most plantations involve a large landowner and, in the past were
associated with slavery, indentured labour, and exploitation.

to fair trade, work relations
and even child labour.

Agriculture in developed countries is usually more
specialised than elsewhere and, as we have mentioned, we
can distinguish farmers who grow plants, those who rear
animals and
others – usually
smallholders –
who practise
mixed farming:
some crops and
some animals.
163. 163
A smallholding is basically a farm of small size run by a
family with a small number (if any) hired hands.
In many parts of the Western
world they are being gradually
replaced by large industrial-
style holdings but their utility
has been recognised by the
EU and, in Europe, such
farms receive assistance to be
able to survive. All farms in
Malta are smallholdings.
169. 169
Cereals are plants belonging to the grass family and grown for
grain They provide carbohydrates (starch) and are the most
important – sometimes the only - source of energy for humans.
Wheat in flower – the elongated structures are stamens, producing
pollen.
170. 170
The most important cereals are:
Maize Rice Wheat
Sorghum Barley Millet
Oats Rye
The top three account for almost 90%
of all grains produced worldwide and
provide more than 40% of calories for
human populations.
172. 172
All cereals are annual plants and can be divided into:
Cool-Season: wheat, barley, oats, rye,
Warm-season: maize, rice, sorghum and millet
Barley and rye
are the hardiest
cereals, able to
overwinter in the
subarctic and
Siberia.
174. 174
With an annual world production of 500-600 million tonnes,
wheat contributes between 10 and 20% of the daily caloric
intake of people in over 60 countries.
175. 175
Wheat (Triticum spp.) is cultivated worldwide. Globally, it
is the second-largest cereal behind maize; the third being
rice. Wheat grain is a staple food used to make flour,
livestock feed and as an ingredient in the brewing of beer.
The husk can

and ground into
bran
177. 177
O. glaberrima is the African rice. It is much less productive
than the Asian rice but is an important source of resistant
genes.
Rice refers to two species of grass (Oryza sativa and
Oryza glaberrima), native to tropical and subtropical
southeastern Asia and to Africa.
180. 180
Maize (Zea mays) is a cereal grain from Central America. It
is called corn in the US, Canada and Australia, but in other.
countries that term
refers to wheat.
181. 181
Maize is grown wherever summers are warm enough and
rainfall or water supply adequate.
It is important as
fodder and, in
developed
countries, the crop
is grown
specifically for this
purpose. The plant
may reach 2 to 4
metres.
190. 190
A grassland is a green, windy, partly-dry biome: a sea of
grass covering almost 25% of the Earth's land area. Deep-
rooted grasses dominate the flora with very few trees and
shrubs.
191. 191
A grassland is a green, windy, partly-dry biome: a sea of
grass covering almost 25% of the Earth's land area. Deep-

192. 192
In nature, grasses often form a habitat that excludes most
other plants so that there are vast stretches of “grasslands”
which would be the
equivalent of the
agricultural
onoculture.
Central Asian grassland
193. 193
There are two types of grasslands according to their latitude:
Temperate Tropical
196. 196
Biomes with hot summers and cold winters. The
evaporation rate is high, so little rain makes it into the rich
soil.

198. 198
Hot all year with wet seasons that bring torrential rains.
Located between the Tropic of Cancer and the Tropic of
Capricorn, sometimes called savannas.
201. 201
Despite the fact that grasslands may be found both in
temperate and tropical regions, it is only in the former that
we find commercial grain-growing on an industrial scale.
202. 202
This is a specialised form of very large-scale farming that is
really possible in areas with natural grasslands. It is also
feasible only where there is sufficient industrialisation and so
its development started in the prairie areas of N. America.
203. 203
The possibility of having large storage capacities is also an
essential condition for the development of commercial
grain-farming.
204. 204
Grain silos are a typical
sight in the landscape of
grain-growing regions
around the world.
206. 206
Nowadays this form of agriculture is found in several other
areas of temperate grasslands in developed countries:
Canada, Australia, Russia, Ukraine and Argentina.
207. 207
In developed countries but
especially in the US and Canada,
grain-growing is associated with
large corporations which control
vast rural areas and trade the
produce as an international
commodity.
The traditional family farm is no
longer of much importance and
being replaced in this sector.
208. 208
In particular in the US, grain
farming has become so
specialised and mechanised
that the “farmer” does not work
the land but only takes
managerial decisions and then
contracts specialist firms to do
the actual work in the field.
209. 209
This is known in America as “suitcase farming” and in Malta
we have a similar situation, albeit on an infinitely smaller
scale.
212. 212
As in North America, agriculture in much of Western
Europe is really agribusiness. This includes widespread
use of machinery and hybrid seeds
Wheat field in Basilicata. S. Italy
213. 213
Besides the ‘real’ grains belonging to the cereal family,
soya (a legume like beans) is also nowadays considered as
a crop typical of grain-farming.
215. 215
Fodder crops are plants that
are grown to feed animals,
especially ruminants and
horses.
The term refers particularly
to plants cut and carried to
the animals, rather than food
which they forage for
themselves.
Fodder includes hay, straw
and other variously
processed plant products.
216. 216
There are two main groups
of such plants, belonging to
two different botanical
families: Cereals
Legumes
The first type contribute
carbohydrates while the
second are rich in protein
(nitrogen).
Clover and lupin are two common
fodder legumes.
217. 217
There are two main groups of such plants, belonging to two
different botanical families:
Cereals

The first type
contribute
carbohydrates and
fibre while the
second group are
especially rich in

218. 218
Although not all fodder crops are cereals we are
considering them in this section (cereal farming) because
they are usually grown together to provide a complete
range of nutrients.

Commercial field or arable farming is essentially the
growing of field crops in arable land.
223. 223
In geography, arable land (from Latin arare, to plough) is
an agricultural term, meaning “land that can be used for
growing crops”.
It is distinct from
‘cultivated land’
and includes all
land suitable for
agriculture, even if
it is not yet under
cultivation.
224. 224
There are various definitions of “field crops”. Cereals are often
included in this category but we have treated them as a
separate type of agriculture so we shall be
considering other crops under this heading.
225. 225
Field crops are basically
vegetables that are
grown in large open
fields rather than the
smallish plots typical of
horticulture.
Tomato fields in the US
228. 228
These can also be of
many unusual colours,
apart from red. Such
varieties, known as
“heirloom” are typical of
horticulture rather than
field cropping.
235. 235
This arrangement is useful to farmers as they have an
assured market but it also puts them in a position of
weakness when negotiating prices and other conditions.
236. 236
There can be environmental concerns in this type of
farming, because of widespread monoculture.
237. 237
In spite of widespread use of machinery, ill-paid migrant
workers are today also essential to field crops in many
European countries and southern US.
238. 238
Nowadays, developing countries are also starting to develop the commercial field
crop production sector. These are irrigated fields in Saudi Arabia

An industrial crop is grown to produce goods, not food.
e.g. to produce fibre for clothing.
Some examples include
flax, hemp, cotton,
tobacco, runbber. Fibre
crops are amongst the
most common industrial
crops.
242. 242
There are three main groups of industrial crops, divided
according to their use:
Energy
Fibres
Other non-food
243. 243
An industrial crop is grown to produce goods, not food. e.g.
to produce fibre for clothing. There are three groups:
Energy - crops used to generate heat, electricity or
produce liquid fuels
Fibres - crops used to produce fibrous material for use in,
for example, car manufacture or insulation
Other - crops with an industrial use other than energy or
fibres.
244. 244
This type of agriculture is being considered under this
section (i.e. agriculture in developed countries) but one has
to note that increasing amounts of such crops are grown in
plantations in developing countries.
246. 246
Crops used to generate heat, electricity or to produce liquid
fuels
247. 247
Crops for heat and electricity generation are chopped up,
and usually burnt directly in stoves and boilers, mixed with
24
7
coal for use in conventional power
stations or used in dedicated
biomass power stations.
248. 248
Under this heading we have several products such as
biodiesel, and bioethanol (a petrol additive/substitute).
At present, biofuels
are usually used as
a blend with fossil
fuel (5% bio to 95%
fossil) for
conventional
engines.
249. 249
Biofuels are a wide range of fuels that are gaining increased
public and scientific attention, driven by factors such as oil
price spikes and the need for increased energy security.

The 'fine linen' mentioned various times in the Bible has been
satisfactorily proved to have been spun from Flax. The
knowledge of spinning was known to the Canaanites and it
formed the clothing of the Saviour in the tomb when He was
buried. It was used for cord and sail-cloth by the ancient Greeks
as well as for lamp-wicks.
254. 254
As a crop, flax is very demanding in terms of nutrients and
rapidly exhausts the soil. It requires care and a rich soil to
secure a good crop.
255. 255
Flax is harvested for fibre
production when still green. It is
pulled up with the roots (not cut),
so as to maximise the fibre
length.
It is then soaked in
water to rot off the
non-fibrous material
in the stems.
.
256. 256
Flax grown for seed is allowed to mature until the seed
capsules are yellow and just starting to split.
The seed is
pressed to produce
a valuable oil.
257. 257
Flaxseed oil is cold pressed from the seeds, and
edible. The seeds are then hot pressed to produce
an industrial oil and solvent, known as linseed oil,
which is not edible.
258. 258
Flaxseed oil has a very high level of omega-3 fats acid so it
is most often used as a nutritional supplement rather than
for cooking.
260. 260
Cotton is a fibre growing around the seeds of the cotton
plant, a shrub native to tropical and subtropical regions
around the world. There are about 50 species of cotton,
but only four are cultivated.
261. 261
Virtually all of the
commercial cotton
grown today worldwide
is from varieties of the
American species.
262. 262
The plant produces creamy-white flowers, which soon turn
deep pink and fall off, leaving the small green triangular
seed pods, known as cotton bolls, which contain the seeds.
264. 264

When the cotton boll is
opened, the fibres dry into
flat, twisted, ribbon-like
shapes and become kinked
together and interlocked.
266. 266
The fibre is spun into thread and used to make the most
widely used natural textile. The English name derives from
the Arabic word al qutun.

270. 270
Tobacco is one of only two
important crops originating
in north rather than
central/south America.
271. 271
The genus Nicotiana belongs to a family producing many
poisonous compounds but also
important crops such as pepper,
potato, tomato, pepper and
aubergine.
272. 272
The biggest producers nowadays are China (40% of the
entire world production) and Brazil (16%)..
The US produces
only about 6% of
the world’s
production
273. 273
Europeans started cultivating it in Virginia but it was imported
into Europe where it became important in Italy and the Balkans.

278. Antoine Vella 278
Horticulture is the subdivision of agriculture dealing with
the gardening of enclosed areas to grow vegetables, fruit
and ornamentals, in contrast to agronomy, which refers to
growing field crops (including industrial crops), and
forestry which concerns forest trees and products related
to them.
279. Antoine Vella 279
Horticulture is sometimes known also as market gardening,
especially when it refers to growing vegetables. It can be
practised as a hobby or an economic activity.
280. Antoine Vella 280
Within the context of this course, horticulture may involve
three types of produce:
• Vegetables
• Fruit trees
• Ornamental plants, especially flowers
281. Antoine Vella 281
The relatively small-scale horticulturalproduction of fruits,
vegetables and flowers as cash crops is also known as
market gardening.
282. Antoine Vella 282
It is distinguishable from other types of farming by the diversity
of crops grown
on a small area
of land, typically,
from about
0.3-3 Ha, or
sometimes in
greenhouses.
283. Antoine Vella 283
Traditionally market gardening is based on providing large
urban areas with a
wide range and
steady supply of
fresh produce
through the local
growing season.
284. Antoine Vella 284
Many different crops and varieties are grown, in
contrast with large, industrialized farms, which tend to
specialise in high volume production of single crops, a
practice known as monoculture.
285. Antoine Vella 285
Compared to field crop farming, market gardening also
employs more manual labour and gardening techniques,
compared to large-scale mechanised farming.
286. Antoine Vella 286
We may also consider the different
aspects of horticulture according to
the medium in which the plants are
grown.
• Soil cultures
• Soilless cultures
287. Antoine Vella 287
Soil culture may be further subdivided into:
• Protected culture with the use of greenhouses
• Semi-protected culture
using small plastic
tunnels
• Non-protected culture
in the open soil.
288. Antoine Vella 288
This type of modern rounded greenhouse is nowadays
sometimes also known as “tunnel”.
291. Antoine Vella 291
Soilless culture is also known as hydroponics since the
plants are basically growing in water, with or without any
substrate.
292. Antoine Vella 292
These may be further subdivided into:
Nutrient Film Technique in which plants are grown in a
water stream
Natural substrate culture using peat
Synthetic
substrate culture
using expanded
clay, polystyrene
(“jablo”), rockwool,
etc
294. Antoine Vella 294
This is a further
development of hydroponics.
The roots of the plants
are suspended in air
and a water with
nutrients is sprayed to
feed them.
296. Antoine Vella 296
Perlite is an amorphous volcanic glass that has a relatively
high water content, typically formed by the hydration of
obsidian.
It occurs naturally and
has the unusual
property of greatly
expanding when
heated sufficiently.

The growing of fruit trees can be considered part of
horticulture system although it can also be found in certain
types of plantations (e.g. date and banana)

There are many ways of classifying fruit trees, including :
• Type of fruit (succulent fruits or nuts)
• Biological cycle (deciduous or evergreen)
• Area of cultivation (temperate, sub-tropical, tropical)
• Use of the product (table or processing)
• Botanical family
301. Antoine Vella 301
The Rosaceae are trees, shrubs
and herbs comprising about 3,000
species which can be very different
in morphology, growth habit, etc.
306. Antoine Vella 306
Traditionally considered as part of the Rosaceae family,
this group is now often treated as a separate family. There
is only one species of importance: the pomegranate Punica
granatum.
307. Antoine Vella 307
The Rutaceae are herbs, shrubs, and trees with glandular, commonly
strongly smelling leaves, flowers and fruit, comprising about 150
genera and 1,500 species. The flowers are often sweet-scented, nearly
always bisexual, and are actinomorphic or sometimes zygomorphic.
Generally, a nectary disc is situated between the stamens and the
ovary. The fruit is variable but in the cultivated species mostly a
specialised berry known as hesperidium.
308. Antoine Vella 308
The Oleaceae are trees or shrubs comprising about 30
genera and 600 species. The fruit is variable but in the only
cultivated species, Olea europea, it is a drupe.
309. Antoine Vella 309
The Fabaceae are mostly herbs but include also shrubs
and trees found in both temperate and tropical areas.
They comprise one of the
largest families of flowering
plants, numbering some
10,000 species. The fruit is
a legume. The only
cultivated fruit tree of
significance is the carob
Ceratonia siliqua.
310. Antoine Vella 310
The Moraceae is a family of about
1,000 species – mostly trees - and
nearly all producing a
milky sap.
311. Antoine Vella 311
The flowers are minute, and usually densely aggregated.
Fruit types include drupes and achenes often aggregated
into a multiple accessory fruit – the syconium

Floriculture is the cultivation of flowering and
ornamental plants for gardens and floristry
The crops include
• Bedding and garden plants
• Cut flowers and foliage
• Houseplants
315. Antoine Vella 315
Bedding and garden plants consist
mostly of young flowering plants
(annuals and perennials).
317. Antoine Vella 317
The cultivation of house plants is a major sector
of horticulture in several developed countries
such as the Netherlands and Italy.
320. Antoine Vella 320
These are produced specifically to be sold after they have
been cut from the mother plant.
Bloom uniformity and the
longevity are the two major
qualities sought by
commercial flower-growers.
321. Antoine Vella 321
When the climate is suitable, this sector can be very
important, with a high added value component.
328. Antoine Vella 328
Dairy farming is a class of
agricultural enterprise for long-
term production of milk, usually
from dairy cows but also from
goats and sheep.
329. Antoine Vella 329
Milk may be either
processed on-site or
transported to a dairy
factory for processing
and eventual retail sale.
331. Antoine Vella 331
In the second half of the 20th century larger farms engaged
only in dairy production have emerged in developed countries.
332. Antoine Vella 332
Large-scale dairy farming is only viable where either a large
amount of milk is required for production of more durable
dairy products such as cheese, or there is a substantial
market for fresh milk.
333. Antoine Vella 333
As in other forms of modern commercial
farming in the developed world, dairy
farming depends on extensive use of
technology and machinery.
337. Antoine Vella 337
In developed countries, milk is not consumed
“raw” but undergoes a certain amount of handling.
338. Antoine Vella 338
Most countries have developed a
whole sector of industry
associated with dairy farming. The
main product of this industry is
undoubtedly cheese.
339. Antoine Vella 339
Cheese is a food made from the coagulated milk of cows,
goats, sheep and other mammals.
340. Antoine Vella 340
It is basically the concentrated fat,obtained through curdling,
of the milk with varying amounts of liquid, according to the
type of product.
341. Antoine Vella 341
The process of cheese-making is an imitation of naturally
occuring reactions in the digestive systems of newborn
mammals.
342. Antoine Vella 342
Newborn mammals cannot chew solid food so they have to
ingest liquids. However a liquid would travel too fast through
the intestine and not allow all the nutrients to be extracted.
343. Antoine Vella 343
What happens therefore is that, inside the stomach, the
liquid milk is curdled (by acids and bacteria) and becomes
solid so that it travels more slowly through the intestinal
tract, thus giving the organism time to digest and absorb all
the nutrients.This solidified milk is, basically, ‘cheese’.
344. Antoine Vella 344
To produce cheese, milk is
warmed to 35-38 C (the stomach
temperature of the calf) then
curdled through the addition of
acids or the action of bacteria.
345. Antoine Vella 345
Thus the fats and proteins in the milk
coagulate and form what is known as ‘curd’
which is actually a form of ‘cheese’.
346. Antoine Vella 346
The curd will then be processed in many different ways
according to the type of cheese being manufactured.

350. Antoine Vella 350
Ranching is the practice of raising large numbers of grazing
livestock (cattle or sheep) for meat or wool (not milk).Cattledrive,SwanVallwy,Idaho
351. Antoine Vella 351
Ranching most often applies to
livestock-raising operations
carried out over extensive
areas in America, though there
are ranches in other regions.
352. Antoine Vella 352
Traditionally horses are used to herd cattle or sheep, though
nowadays, motorised transport is becoming more common.
353. Antoine Vella 353
Ranching and the “cowboy” tradition originated in the
Mediterranean, especially in Spain, out of the necessity to
handle large herds of grazing animals.
354. Antoine Vella 354
Because grazing land was poor, large areas were
needed for the herds and, before the Industrial Age, the
livestock could be controlled only on horseback.
355. Antoine Vella 355
During the Reconquista, Christian nobles received large
land grants that the Kingdom of Castile had conquered
from the Moors. These landowners were to defend the
lands put into their control and could use them for earning
revenue.
356. Antoine Vella 356
In the process it was found that open-range breeding of
sheep and cattle was the most stuiable use for vast tracts.
Particularly in the part of Spain now known as Castilla-la
Mancha, Extremadura and Andalusia
Countryside in Extremadura. SW Spain
357. Antoine Vella 357
Even today, large areas of Spain are dedicated to extensive
ranching, especially of sheep
Flock of Merino sheep outside Avila
358. Antoine Vella 358
In other parts of the Mediterranean, a similar type of animal
husbandry also developed especially in Maremma
(Tuscany) and the mouth
of the Rhone.
359. Antoine Vella 359
The Camargue is nowadays a
wetland nature reserve,
renowned for its breeds of open-
range horses and cattle.
360. Antoine Vella 360
This type of farming is also found in the
S.Tuscany region of Maremma.
361. Antoine Vella 361
The first Spanish settlers in America brought their cattle
and cattle-raising techniques.
Huge land grants by
Spanish (and later
Mexican) governments
allowed large numbers
of cattle to roam freely
over vast areas.
362. Antoine Vella 362
The prairies of North America proved to be perfect as
grazing land for cattle and, together with cereal-growing,
this became the primary agricultural activity of the region
363. Antoine Vella 363
Ranching and cereal-growing
gradually took over entire regions
of N. America, pushing out the
indigenous fauna.
364. Antoine Vella 364
Although we’re considering ranching as an agricultural
activity of developed countries, it has also been introduced
in some other regions (notably Brazil and Argentina) to
satisfy the demand for beef in the developed world
365. Antoine Vella 365
In the colonial period, from the pampas regions of South
America all the way to the Minas Gerais state in Brazil, were
often well-suited to ranching, and
a tradition developed that largely
paralleled that of N. America.
367. Antoine Vella 367
The gaucho cultures of Argentina, Brazil and Uruguay are
among the ranching traditions born during the colonial period
368. Antoine Vella 368
In the 20th century, ranching expanded into less-suitable
areas of the Pantanal (Mato Grosso – a wetland) in Brazil.
This caused extensive deforestation, as the rainforest
was cleared to allow grass to
grow for livestock.
369. Antoine Vella 369
Many of indigenous peoples of the rain forest opposed this
form of cattle ranching and protested the forest being burnt
down to set up grazing operations and farms. This conflict
is still a concern in the region today.
370. Antoine Vella 370
In Australia, the ranches are known as 'stations' raising
either cattle or sheep. The largest cattle stations in the
world are located in Australia's dry rangeland in the
outback averaging 10 thousand km2.
371. Antoine Vella 371
Anna Creek Station, in South
Australia, is the world's largest
cattle station. Its area is roughly
24,000 km². (6,000,000 acres) of
semi-desert which can support only
small numbers of animals.

374. Antoine Vella 374
Intensive livestock
farming involves
the breeding
and/or rearing of
large numbers of
animals, often in
confined spaces.
375. Antoine Vella 375
In this presentation we shall be considering poultry and pigs
although other species, such as rabbits, may also be farmed
this way.
376. Antoine Vella 376
Poultry farming is the practice of raising domestic birds such
as chickens, turkeys, ducks, and geese for the purpose of
farming meat or
eggs for food.
377. Antoine Vella 377
More than 50 billion chickens are raised throughout the
world every year as a source of food, for both their meat and
their eggs.
378. Antoine Vella 378
Chickens raised for meat are called broilers, whilst those
raised for eggs are called laying hens or layers. Some hens
can produce over 300 eggs a year.
379. Antoine Vella 379
Broilers are generally held in large groups either in
environmentally controlled housing or in open, naturally
ventilated poultry houses.
380. Antoine Vella 380
They are usually kept free on deep litter with automated
provision of feed and water. In most countries, commercial
breeds selected for rapid growth, are used.
381. Antoine Vella 381
In 2010 a new EU directive
imposed a maximum bird
density which must not
exceed 33-39 kgs per m2.
Density is calculated by kg per
m2 because the smaller the birds
the less space they need.
382. Antoine Vella 382
In egg production, the majority of commercial layers are kept
in battery cages.
There is wide variation in space allowance per bird from 300
to 400 cm2 in places such as Brazil or India to the current
550 cm2 per hen in the EU.
383. Antoine Vella 383
After 2012, hens in the EU will be kept in cages with a
minimum space allowance of 750 cm2 per hen (from 550 cm2).
384. Antoine Vella 384
Chickens will naturally live for 6 or more years but after one
year, their productivity will start to
decline and most commercial
laying hens are slaughtered
at that age.
385. Antoine Vella 385
Poultry which is kept in the open – usual having a light
density per m2 – is said to be free range but this is more
typical of mixed farming.
386. Antoine Vella 386
Intensive pig-farming consists in keeping large numbers of
pigs in indoor pens while pregnant sows are housed in
“cages” known as farrowing crates.
387. Antoine Vella 387
The use of farrowing crates
has resulted in lower
mortality among newborn
piglets and decreased costs.
388. Antoine Vella 388
In general, however, the over-intensification of pig-farming
gives rise to concern about animal welfare especially as
regards overcrowding and lack of space which causes
physical and mental
stress to the animals.
389. Antoine Vella 389
Most large-scale pig farms house 5,000 or more animals in
buildings. With 100 million pigs slaughtered commercially
each year, these efficiencies deliver affordable meat for
consumers and larger profits for producers.

392. Antoine Vella 392
This is a system of farming where different types of
agricultural practices are conducted together, on a single
farm.
393. Antoine Vella 393
On such a farm we will therefore find both the growing of
crops and the raising of livestock.
Crop-livestock
integration: sheep
grazing under tall-
stemmed fruit trees
(the Netherlands)
394. Antoine Vella 394
Because of the lack of specialisation, mechanisation is
more difficult and such farms are usually small.
395. Antoine Vella 395
Although, for convenience’s sake we’re considering mixed
farming as a system of developed countries, it can of course
be found even in developing regions.
Crop and livestock

396. Antoine Vella 396
Nowadays many mixed farms in countries like Italy, Spain
and France supplement their income by organising tourism-
related activities.
400. Antoine Vella 400
Although the name of this type of climate derives from the
basin of the Mediterranean Sea it is, in fact found in several
other places round the world.
402. Antoine Vella 402
The most prominent features of this climate are the long hot
dry summers and the mild wet winters, with temperatures
that rarely reach 0 C.
403. Antoine Vella 403
Another relevant character is the chronic lack of water which
has a significant impact on agriculture.
404. Antoine Vella 404
This is distinctive and has been developing since ancient
times. It is traditionally a subsistence type and although it
has become more commercialised in areas such as
California, Australia and
some parts of Italy,
smallholdings are still
the norm in most
countries of the
Mediterranean basin
itself.
405. Antoine Vella 405
Another feature of the Mediterranean basin is the scarcity of
large plains suitable for cattle.
406. Antoine Vella 406
As a result, agriculture is based mostly on
crop farming complemented by small
ruminants.
407. Antoine Vella 407
As regards crops the characteristics include:
• A crop rotation of 4-5 years
• Extensive drought-resistent tree crops.
408. Antoine Vella 408
A typical Mediterranean crop
rotation is based on cereals
(wheat and barley) and legumes
(beans and/or fodder).
409. Antoine Vella 409
The most economically important tree crops are the olive,
grapevine, citrus, stone fruits and - in the southern coast of
the Med. Sea – date palms.
410. Antoine Vella 410
Olives are the symbol of Mediterranean agriculture. The
Mediterranean itself is defined as the region where the olive
tree grows.
411. Antoine Vella 411
Although the grapevine originated
outside the Mediterranean area, its
cultivation – and the consequent
wine culture - has also become
synonymous with the region
412. Antoine Vella 412
Because of the high population density and the numerous
settlements all around the Mediterranean basin, market
gardening is also
important, where
water is available.
413. Antoine Vella 413
The Mediterranean and its agriculture will be the topic of
another presentation where it will be discussed in more
detail.
