This document discusses population growth, sustainable land management, and their relationship in India. It notes that many developing countries like India face problems of high population growth creating issues like poverty, food crises, and land degradation, while resources like land are limited. Sustainable land management is necessary to ensure land productivity and quality for current and future generations. The concept of sustainable land management aims to use renewable land resources like soil, water, and plants in a way that protects long-term productivity while allowing for economic and social benefits.
1. Rapid population growth in India is threatening the environment through expansion of agriculture, uncontrolled urbanization and industrialization, and destruction of natural habitats.
2. Growing population puts pressure on land and resources, leading to issues like land degradation, soil erosion, deforestation, and pollution of water and air.
3. Population growth contributes to environmental degradation by increasing demand for food, housing, energy, and other resources, intensifying land use and degrading forests and land. Rising consumption also increases pollution and stresses ecosystems.

Human population growth and increased affluence are placing major stresses on the environment and society's limited resources. Technology and engineering will be central to monitoring and addressing these problems, as well as creating sustainable solutions. However, predicting the future remains difficult due to uncertainties. The next 25-50 years will be decisive for mitigating stresses on the planet.
The document discusses the major increases in human population and consumption that are putting significant stress on the environment. The growth of the human population from millions to billions in just a few centuries due to technology and medicine is depleting resources and damaging ecosystems. Continued population and economic growth will further degrade the environment unless new technologies can be developed to mitigate these problems. Engineers have a key role to play in measuring environmental impacts, creating sustainable technologies, and helping develop solutions to address the challenges of supporting the human population while protecting the planet.
population development and environment is not directly linked but yet there is a indirect complex relationship between population development/ activities and environment for example urbanization, slums , mega cities emerge and the use of natural resources mush faster then they replanish
International conference on population and developmentpadek
This document discusses sustainable development and aims to ensure human well-being while preserving the environment for current and future generations. It notes that population growth, consumption patterns, and environmental degradation are accelerating issues that present challenges but also opportunities to adopt policies and plans that promote sustainability. The document references comments from Al Gore about these issues being among the greatest challenges of the coming century.
Relationship Between Population,Environment and Developmenteshamwata
This document discusses the relationship between population growth, development, and the environment. It notes that population growth and increased development activities place stress on the Earth's natural resources and can lead to environmental degradation. Several schools of thought are described that have different perspectives on this relationship, such as Malthusians who believe population growth will exceed resources, and neoclassical economists who believe human innovation will overcome resource scarcity. The document outlines global efforts to address the impacts of population growth on the environment since the 1970s. It concludes that alleviating poverty, empowering women, and developing more sustainable lifestyles are critical to providing a decent quality of life without damaging the environment.

The document discusses human population growth and its environmental impacts. It notes that the world population grew from 300 billion in AD 1 to over 6 billion in 2000 and is projected to reach over 9 billion by 2050. This rapid growth is called a population explosion. The explosion is driven by decreased mortality rates due to improvements in food production, public health, and medicine. Effects of the explosion include overstressing natural resources, increased pollution, food shortages, and unemployment. Air and water pollution increase as industries and vehicles grow to serve larger populations, which also leads to deforestation for new lands. Managing this explosion will be a major challenge going forward.
Human Population Growth and Environmental ImpactsBilhami
Global human population has grown over the past century from 6.7 billion in 2006 to a projected 9.2 billion by 2050, with the largest increases in India, China, and Southeast Asia. This population growth puts pressure on food production and resources, and generates more waste and pollution, disrupting ecosystems. While some countries have seen population declines through high death rates and low birth rates, environmental impacts are linked more to consumption patterns of larger populations and levels of economic development rather than just the number of people.
Population growth implications for environmental sustaintabilityarmandogo92
This document discusses the implications of population growth in Nigeria for environmental sustainability. It notes that rapid population growth and increasing demand for natural resources is disrupting natural ecosystems and undermining their ability to support populations at current levels. The carrying capacity of the environment is exceeded when populations grow too large relative to available resources. Problems caused by Nigeria's growing population include soil erosion, land degradation, and habitat loss due to increasing agricultural and development pressures on the land. For sustainable development, population size and growth must be balanced with the environment's productive capacity.
This document discusses the relationship between the human population, environment, and health. It outlines several key topics in this area, including environmental health issues like climate change, infectious diseases, water-related illnesses, and cancer risks from chemicals. The document emphasizes that human health is directly impacted by environmental damage. It also discusses the importance of sustainable development, equitable access to natural resources, and protecting cultural heritage and social justice. Overall, the main message is that human population growth puts pressure on the environment in ways that can negatively impact human health and rights.
This document discusses human population and its relationship to the environment. It covers topics like population ecology, growth, density and carrying capacity. It also discusses factors governing human settlement like land, food, water and energy resources. It describes population pollution due to overpopulation exceeding environmental carrying capacity.

this presentation is aimed to describe either population growth is a major factor in environmental change or somethings else is underlying in this phenomenon?
Rapid population growth increases pressure on limited resources like water, forests, land, and the atmosphere. Providing access to family planning can help slow population growth and ease environmental pressures. Achieving universal access to contraception and reproductive health services would improve health outcomes for women and families while also helping address environmental challenges. Family planning is an opportunity to boost resilience to environmental issues by enabling smaller, healthier families.
This document discusses human population growth and its relationship to the environment. It defines key population concepts like population size, density, natality, mortality, doubling time, total fertility rate, and age structure. Rapid population growth can lead to overpopulation, depletion of natural resources, increased waste production, and food and unemployment issues. India faces a population explosion due to high birth rates, early marriage, poverty, illiteracy, cultural norms favoring male children, and illegal migration. The government of India has implemented family welfare programs to promote family planning and reduce birth rates.
This document provides a geography IGCSE revision guide covering various themes related to population, settlements, the natural environment, and economic development. It includes case studies for different topics within each theme. For population dynamics, it summarizes a case study on rapid population growth in Niger, highlighting high fertility rates, limited resources, and proposed solutions like increasing family planning education. It also briefly outlines case studies on China's one-child policy and population policies in Singapore and Italy aimed at increasing low birth rates.
The document discusses population growth and its impact on the environment. It defines key population terms like population size, density, and growth rate. Population growth is influenced by birth rate, death rate, and migration. Rapid population growth can cause problems like increased demand for resources and loss of agricultural land. Family planning programs aim to promote small family sizes and provide healthcare to support family welfare. Variations in population structures among nations are also examined.
The document discusses various topics related to human population growth including:
1. A brief history of human population growth from early hunter-gatherer societies to the rise of agriculture and cities.
2. The demographic transition from high birth/death rates to low birth/death rates as countries develop.
3. Current population growth trends with most growth occurring in developing countries and the potential challenges of overpopulation.
4. Methods to influence population size such as family planning programs, education/empowerment of women, and potential social/economic impacts of population decline or aging populations.
This presentation tells about how climate change is happening due to the population and its impact on the environment in terms of ecological impacts etc.
Overpopulation by The Eco Warriors (Samuel Amid Jr, et al)Samuel Jr Amid
Overpopulation occurs when the human population exceeds the environmental carrying capacity of Earth. Falling mortality rates due to advances in medicine and food production contributed to unchecked population growth. Migration to cities also increased populations, concentrating their environmental impact. Unrestrained consumption of resources has led to environmental degradation from pollution, deforestation, and species extinction as the population deficit is reached earlier each year. Potential solutions discussed include increasing access to sex education and contraception, promoting family planning, and educating people about the dangers of overpopulation.

The document discusses global population trends, noting that China and India currently have the largest populations but India is projected to surpass China by 2030. Developing countries are experiencing rapid population growth during a time when resources are already stressed. Rapid population growth can overwhelm infrastructure and resources, affecting access to necessities like fuel, water, arable land, and adequate housing. Some governments try to address overpopulation through incentives for smaller families and increased access to family planning.
This document summarizes a journal article about sustainable water management and international trade. It discusses how water resources are unevenly distributed globally and how this leads to differences in production techniques and opportunities for international agricultural trade. It notes that while water-intensive agricultural exports can generate significant earnings for some countries, it also represents a loss of scarce water resources. The document advocates for policies that promote sustainable agricultural growth while considering a country's water endowment.

It emphasizes the need to understand ecosystems and modify human activities to conserve resources for the long term.
Natural Resource Management and Bio-Diversity Conservation in Indiaijceronline
1) The document discusses natural resource management and biodiversity conservation in India. It notes that India has a large population and livestock population putting pressure on shrinking natural resources.
2) Key issues addressed include biodiversity loss, the impacts of human and economic development on the environment, and the connections between energy, natural resources, and the environment. Sustainable management of resources like forests, water, land, and wildlife is important for economic growth, food production, and community livelihoods.
3) The document examines causes of land degradation globally like deforestation, overgrazing, fuelwood consumption, agricultural mismanagement, and urbanization, and the need to balance development and environmental protection.
An efficient allocation of resources that adequately accounts for natural capital. Traditional economics (including environmental economics - defined as the application of traditional economics to environmental problems) has focused on a third of these problems (efficient allocation) and therefore has not fully addressed the issue of sustainable development.
This document provides an introduction to green skills and sustainability topics including the environment, ecosystems, natural resource conservation, and green economy. It discusses how society and the environment interact and depend on one another. Factors like pollution, climate change, and overuse of resources can upset the balance of ecosystems. Conservation aims to protect natural resources for future generations. Environmental protection involves public awareness campaigns and international agreements to address issues like pollution. Transitioning to a green economy can improve well-being while supporting the environment through more sustainable use of resources and creating green jobs.
Biodiversity conservation is important for sustainable development and improving human welfare. Biological resources need to be protected while allowing sustainable use. Over 350,000 hectares of forest are lost annually in Nigeria, degrading habitats and endangering species. Effective conservation prevents environmental destruction and degradation. Biodiversity exists at genetic, species, and ecosystem levels and results from interactions between organisms. Wildlife conservation aims to maintain indigenous species in diverse landscapes.

Presentation from Salman Hussain, United Nations Environment Programme (UNEP) describing TEEB Agriculture and Food, a study designed to provide an economic evaluation of the ‘eco-agri-food systems’ complex. The presentation was prepared and delivered in occasion of the International Symposium on Agroecology for Food Security and Nutrition, held at FAO in Rome on 18-19 September 2014.
Agriculture sustainability and food security is important to ensure future development and meet the needs of a growing global population expected to reach 11 billion by 2050. Sustainable agriculture aims to increase production without compromising future generations' ability to meet their needs by considering factors like water and soil management, energy and wildlife conservation, and reducing reliance on non-renewable resources. Achieving sustainable agriculture requires efforts across the entire food system from producers to consumers and changes to policies, institutions, and social values.
Agriculture sustainability and food security is our insurance policy for futu...Howard Barmil
This is an academic lecture and discussion which was done at the University of Jordan in college of agriculture; this lecture was made for the PHD candidates.
Sustainable agriculture is the system of farming (cultivating land, harvesting and selling farm products), while enhancing wise rural land development in concert with community interests and environmental protection. We must meet the needs of the present without jeopardizing or compromising the ability of future generations to meet their own needs.
Understanding sustainability.
We must envision the broadest sense; it starts at the individual farm, and ends at the consumer’s table going through the full cycle of the ecosystem (farmers, farmworkers, consumers, policymakers and others). An emphasis on this ecosystem circle allows a larger and more thorough view of the consequences of farming practices on both human communities and the environment. A systematic approach gives us the tools to explore the interconnections between all agents in this ecosystem cycle.
This document discusses approaches for water sustainability in India. It notes that while India has a large population, it only has 4% of the world's renewable water resources. The document outlines challenges around uneven rainfall distribution and frequent floods and droughts. It recommends adopting integrated water resource management and a holistic approach that focuses on water conservation techniques like watershed development, rainwater harvesting, and conjunctive use of surface and groundwater. The goal is to balance water supply and demand in a sustainable manner that supports ecosystems and human needs over the long term.

A universal model for managing the marketing executives in nigerian banksAlexander Decker
This document discusses a study that aimed to synthesize motivation theories into a universal model for managing marketing executives in Nigerian banks. The study was guided by Maslow and McGregor's theories. A sample of 303 marketing executives was used. The results showed that managers will be most effective at motivating marketing executives if they consider individual needs and create challenging but attainable goals. The emerged model suggests managers should provide job satisfaction by tailoring assignments to abilities and monitoring performance with feedback. This addresses confusion faced by Nigerian bank managers in determining effective motivation strategies.

A survey paper on sequence pattern mining with incrementalAlexander Decker
This document summarizes four algorithms for sequential pattern mining: GSP, ISM, FreeSpan, and PrefixSpan. GSP is an Apriori-based algorithm that incorporates time constraints. ISM extends SPADE to incrementally update patterns after database changes. FreeSpan uses frequent items to recursively project databases and grow subsequences. PrefixSpan also uses projection but claims to not require candidate generation. It recursively projects databases based on short prefix patterns. The document concludes by stating the goal was to find an efficient scheme for extracting sequential patterns from transactional datasets.

This document surveys trust architectures that leverage provenance in wireless sensor networks. It begins with background on provenance, which refers to the documented history or derivation of data. Provenance can be used to assess trust by providing metadata about how data was processed. The document then discusses challenges for using provenance to establish trust in wireless sensor networks, which have constraints on energy and computation. Finally, it provides background on trust, which is the subjective probability that a node will behave dependably. Trust architectures need to be lightweight to account for the constraints of wireless sensor networks.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Abstract
Most of the developing countries including India face a dilemma problem of high population growth
creating poverty, food crisis and land degradation at the same time the resources like land, water, nutrients
and energy are limited in supply. These countries are primarily based upon agriculture and hence a
sustainable long-term agricultural growth can only alleviate poverty. Most of the population is engaged in
agriculture. Again land which is fixed in supply by nature is the primary input for agricultural production.
The poor farmers want to maximize their income earned from this sector in the short-run. But the societal
problem is to maintain long-term benefit and biodiversity in flora and fauna and maintain the quality,
productivity and stability not only for the present but also for the future generations. Land degradation is a
global issue of the 21st century and by the year 2050 it may create a serious threat to food production,
adverse impact on agronomic productivity, the environmental pollution, food security and quality of life.
Hence a proper planning and management of the available land resource is necessary to ensure maintenance
of their production potential, quality and diversity. The health and wealth depends primarily upon the
quality of land. Hence the limited scarce land resource must be used in a socially acceptable eco-friendly
manner. The Sustainable Land Management (SLM) may solve the crucial problem.
Keywords: Food crisis, GHGs, degradation, green revolution, pollution, sustainable
1. Introduction
Professor W.A. Lewis writes: “The extent of a country’s resources is quite obviously a limit on the amount
and type of development which it can undergo. Natural resources determine the course of development and
constitute the challenge which may not be accepted by the human mind.” Natural resources include land,
water, fisheries, minerals, forests etc. Some of these resources are non-renewable and exhaustible (like
minerals) and some are renewable (like land). It should be mind that the total supply of land is fixed and is
a free gift of nature i.e. its supply is perfectly in-elastic. Although a piece of land can be used for several
purposes in several times the fertility of land must be deteriorated. But it is necessary to maintain the
quality of land in the process of economic development. For an individual three basic essential things are
required for his survival: food, clothing and shelter. In the primitive community when man lived in jungles
he did not have clothing or even shelter (Bairagya R. and Sarkhel J. 2011). But he needed food to survive.
Animals can live without clothing or shelter but also need food. Plants also need food. While plants can
make their own food man and other animals have to produce or collect food. Thus for all living beings food
is the most essential component of life. It is necessary for getting energy which man needs for doing
different works. Even when a man is sleeping his major organs like heart or lungs remain active. These are
functioning from birth to death at a stretch. To continue these activities energy is required which can be
derived from food. For production of food agricultural land is a necessary input. Due to rapid growth of
population food crisis arises. To increase agricultural production more cropped area is required. To do this
more grazing, forest and wastelands are brought into cultivation and cropping pattern such as single crop to
multiple crop use in a single agricultural year is required.

the environment so that these needs can be met not only in the present, but also for future generations. The
term was used by the Brundtland Commission which coined what has become the most often-quoted
definition of sustainable development as development that “meets the needs of the present without
compromising the ability of future generations to meet their own needs”. It is usually noted that this
requires the reconciliation of environmental, social and economic demands - the “three pillars” of
sustainability. This view has been expressed as an illustration using three overlapping ellipses indicating
that the three pillars of sustainability are not mutually exclusive and can be mutually
reinforcing. Sustainable development ties together concern for the carrying capacity of natural systems with
the social challenges facing humanity. As early as the 1970s “sustainability” was employed to describe an
economy in equilibrium with basic ecological support systems [Wikipedia]. A primary goal of sustainable
development is to achieve a reasonable and equitable distributed level of economic well being that can be
perpetuated continually for next generation. Thus the field of sustainable development can be broken into
three constituent parts i.e. environmental, economic and social sustainability. It is proved that socio-
economic sustainability is depended on environmental sustainability because the socio- economic aspects,
like agriculture, transport, settlement, and other demographic factors are born and raised up in the
environmental system. All the environmental set up is depended on a piece of land where it exists.
Sustainable land management is necessary for the existence of human society.
3. Concept of Sustainable Land Management
Land degradation is a global challenge for sustainable development. The main problem of the world is
the sustainability of natural land resources due to soil degradation, the availability of water and the loss of
bio-diversity. About one third of the world’s agricultural land has been damaged mostly by soil loss caused
by water erosion. Natural resources can potentially be used in a sustainable way if appropriate land
management technology, regional planning and the policy framework complement one another in a
purposeful way, in accordance with the principles and concepts of sustainable land management (SLM)
means the use of renewable land resources (i.e. soil, water, plants and animals) for production and services
while protecting the long-term productive potential of these resources (Michael Stocking 2008). For the
coexistence with nature so that the productive, physiological, cultural and ecological functions of natural
resources are maintained for the benefits of the society. Our challenge is to harmonize the complementary
but often conflicting goals production and environmental protection. UNCED estimated that 5to7 million
hectares of productive land is degraded every year and affecting more than 2.6 billion people in the world.
According to H. Hurni (1997) SLM has been defined as “a system of technologies and/or planning that
aims to integrate ecological with socio-economic and political principles in the management of land for
agriculture and other purposes to achieve intra-and intergenerational equity.” SLM thus composed of three
development components technology, policy and land use planning. Management is simply defined as an
activity on the ground, using appropriate technologies in the respective land use systems. A sustainable
technology has the following 5 pillars: ecologically protective, socially acceptable, economically
productive and viable and reduce risk. According to Dumanski J. (1997) the objective of sustainable land
management is to harmonize the complementary goals of providing environmental, economic and social
opportunities for the benefit of present and future generations, while maintaining and enhancing the quality
of the land resource. Land provides an environment for agricultural production, but it is also an essential
condition for improved environmental management i.e. source for GHGs, recycling nutrients, ameliorating
and filtering pollutants, transmitting and purifying water. The SLM can be shown as: Sustainable soil
management- Sustainable agriculture- Sustainable land management- Sustainable resource management-
Sustainable development. Expanding human population and economic activities are placing ever-increasing
pressure on finite life supporting resource land.
The SLM Module defined many functions of land resources are to produce food, fodder, fuel,
construction material, industrial goods, etc to ensure human health by minimizing toxic substances in water,
soils and plants, or hazards such as landslides, flash floods, etc. to preserve creation and the integrity of the
landscape: the role(s) of water, land, forests and animals as an essential part of the cultural heritage, and to
maintain the historical and aesthetic value of the landscape, to ensure maintenance of ecosystem functions
and global life support functions, including source/sink capacity for GHGs, filtering of water and pollutants,
and maintenance of global geochemical (nutrient) cycles, etc. SLM can be approached by looking for

symptoms of unsustainability, such as soil degradation, water quality decline, loss of biodiversity, increased
incidents of plant diseases, etc. Such symptoms are a result of inappropriate land management and
exploitation of resources, the causes of which are often societal and political rather than technical or
agronomic. SLM can also be approached through analyzing the options to manage the land sustainably.
4. Population growth in India
According to 2011 Census, India’s population increases 181 million people from 1.03 billion in 2001 to
1.21 billion in 2011(Visaria L. 2011). The decadal growth rate of population is 17.6% compared to 21.2%
during 1991-2001 suggesting a slowdown of growth. The sex ratio of population has began to improve
from 927 in 1991to 933 in 2001to 940 in 2011. The overall literacy rate is in 2001 is 745 with 82.1% male
and 65.55 female literacy rate. The child sex ratio has fallen from 945 in 2001 to 927 in 2001 to 914in 2011.
At the end of October 2011, the world population crossed over 700 crores, China 135 crores and India 124
crores. Though India possesses only 2.4% of world geographical area it covers 17.71 % of total world
population. It is expected that India will become the most populous country in the world by 2030
overtaking China. India’s population size is expected to stabilize at 1.8 billion at 2041.The state Uttar
Pradesh is the most populous state in India with 199.6 million people covering 16.5% of country’s
population. This high growth of population is main retarding factor of environmental degradation.
4.1 Land Resources in India
According to Central Statistical Organization (2002) the total geographical area is 306 million hectares
(Datt and Sundharam 2010). Out of this 42 million hectares (i.e.14%) is barren land such as mountains,
deserts, lands occupied by buildings, roads and railways, rivers, canals and others which cannot be brought
under cultivation. 69 million hectares of land (i.e. 23%) area is under forests includes all land whether
state-owned or private and whether wooded or maintained as potential forest land. Pastures, meadows and
village common grazing land occupied 11 million hectares (i.e. 4%) only. The cultivable waste land means
land available for cultivation but not cultivated during the last 5 or more years and these lands may either
be fallow or covered with shrubs and jungles which are not put to any use. This area covered for 18 million
hectares (i.e. 6%). Fallow lands are cultivable but remain uncultivated during some period of time due to
unremunerative nature of farming, poverty of the cultivators, inadequate supply of water, silting of canals
and rivers etc. This land accounts for 25 million hectares (i.e. 85). Now the total agricultural land is 193
hectares (i.e. 66%), out of which 140 hectares is net area which is used once in a year and 53 hectares are
cultivated more than once in an agricultural year.
5. Population Growth and Land Degradation
5.1 Malthusian Theory
Rapid growth of population over the world is the main cause of food crisis. According to Malthus
population increase at G.P. rate (e.g. 2,4,6,8,10,……..) while the supply of food increase at A.P. rate (e.g.
2,4,8,16,32,……) i.e. population grow at a higher rate than he food supply and create food scarcity. This
shortage of food gives rise to famines, epidemics, food riots etc. Due to these calamities a part of
population is eliminated and a natural balance between population and food supply is established only in
the short-run because again population begins to grow at a faster rate than food supply and the economy
again moves to food crisis. In this way food crisis arises in an economy at a regular interval. Malthusian
theory is based on the agrarian economy. Since the supply of land cannot be increased beyond a certain
limit intensive cultivation would have to be adopted for increasing the volume of production. Intensive
cultivation means application of more labor and capital on a fixed amount of land which follows the law of
diminishing return with no technological progress. By introducing new improved technology it is possible
to postpone the operation of the law of diminishing return. By means of this introduction of new innovative
techniques in agricultural production the western countries of the world are able to escape from this. Even
if the Malthusian theory has been discarded, the shadow of Malthus is still haunting us. Moreover by means
of intensive cultivation using new techniques and chemical fertilizers the fertility of land is deteriorated day
by day. The SLM is the main objective here to feed the rapidly rising population at the same time maintains
the bio-diversity of the environment. A balanced land management can achieve both economic and
environmental Sustainability.

5.2 Water Scarcity
Scarcity of water is a global problem today (Bairagya R. and Chakraborty K. 2011). For agricultural
production huge amount of water is required. In most of the developing countries, population is primarily
engaged in agriculture which is the primary source of income to maintain their livelihood. Again
agricultural production is the gambling of rainfall. To raise agricultural productivity various dams have
been made in an unplanned way which have adversely affected to the commons and the environment. To
control flood and supply irrigation water the construction of big dams have rarely helped. In villages for
irrigation many tube-wells and submersibles have been installed in an unplanned way (it should not be
bored less than 1000 feet) which use the ground- water in a massive scale and consume a huge amount of
electricity. As population raises the scarcity of food grains rises. Food scarcity is highly
positively-correlated with water scarcity. According to Lester Brown, “Water shortage may soon become
food shortage”. Rice, wheat and sugar-cane together constitute 90% of total water consuming crops. From
the economic point of view, return of water in industrial sector is many times more attractive than in
agriculture. Approximately 1000 tons of water is required to produce only one ton of wheat. This
monetary return is much lower than if this water is invested in industrial sector. In this case the non-food
grains like fruits, vegetables and animal products for daily food intake should be raised as substitutes to rice
and wheat. To meet the heavy demand for food the pressure on land must be increased.
5.3 Environment pollution
Environmental pollution is indirectly responsible for land degradation. In the last few decades several
measures have been adopted for increasing agricultural production which has adverse effects on natural
environment. Fertility of land has been reduced due to over exploitation, excessive use of chemical
fertilizers, insecticides and pesticides. Due to indiscriminate deforestation the amount of rainfall reduces
and land erosion takes place. Natural calamities like droughts, floods, cyclones, global warming, melting
glaciers, raising sea level etc. are increasing and environment is degraded. As a result the production of
food grains decreased and made food crisis at a global level. Naturally a question arises: Is environmental
degradation not acceptable for meeting the food crisis and maintaining food security? In answer to this
question it can be said that additional food grains can be produced in the short-run by degrading the
environment but this food security will not be sustainable. This is so because food security for the present
generation can be maintained by the degradation of the environment but then food security for the future
generation cannot be maintained. For permanent cure SLM is necessary here.
5.4 Industrialization
As population rises Production use of land (which is fixed in supply by nature) for non-agricultural
purposes increases due to rapid urbanization in building roads, houses, factories etc even the fertile land is
used for non-agricultural purposes. Norman Borlaug rightly told, “When people fail to recognize farmers’
role in feeding the country, be sure there is something terribly wrong happening.” Most of the developing
countries believe that industrialization is the only key indicator for economic development and increase in
national income. Hence even if they have comparative advantage in agriculture they are bent on
industrialization at any cost. Even fertile agricultural lands are being used for setting up industries. Not only
had that to make buildings and factories huge amount of bricks required. To produce this volume of land
soil is definitely decreased and land is degraded.
5.5 Soil Erosion and deforestation
Direct impacts of agricultural development on the environment arise from farming activities, which
contribute to soil erosion, land salination and loss of nutrients (Ray S. and Ray I. 2011). The main causes of
soil errosion are runways of waterbodies, floods, deforrestations etc. Due to rapid growth of population a
huge amount of wood, wooden furnitures, for making new buildings many forest areas are vanished beyond
limit. The forest areas has dual roles to maintain environmental balance by directly reducing air pollution on
the one hand and check for soil errosion on the other. But the tragedy is that this common property bis
misused by many ways Thus for SLM new plantation and afforestation must be required.

The main cause of global warming is the increase in GHGs in the atmosphere. Due to increase in temperature
the amount of ice in the glaciers has drastically fallen raising the sea level and some countries will be
immersed under water and on the other hand the rivers, lakes and springs which are filled up by melting ice
supplying water throughout the year will be dried up during summer and finally create water scarcity for
irrigation and drinking purposes. It is expected that some countries in the world will immersed into water due
rise in sea level and finally decrease the available land for utilization purposes. Thus pollution control may be
an alternative way to SLM.
5.7 Use of fertilizers and pesticides
To solve food crisis a major change in Indian agriculture occurred in the form of Green Revolution using
Chemical fertilizers to agricultural land to increase land productivity. The excessive use of pesticides,
fertilizers and HYV is an important factor for land degradation particularly salination, alkalization and finally
the quality of land must be deteriorated. It is evident that Indian economy is based primarily on agriculture.
But most of the land in the country is degrading and affecting the productive land resource of the economy.
Besides the loss of nutrients from top soil, there is also degradation through the creation of gullies and
ravines, which make the land unsuitable for agricultural production. This is the major evil effects of Green
Revolution. SLM is one of the iportant few options for land users to generate income without destroying the
quality of the land on the production process.
5.8 Poverty
Rapid growth of population is the main cause of poverty and unemployment. As they have no alternative
occupations the unemployed people are forced to engage in agriculture and create disguished unemplyment
whose marginal productivity tends to zero. Most of India's poor live in rural areas and are engaged in
agriculture. The rapid population growth and poverty are found to coexist and thus seems to reinforcing each
other in a cyclical manner. The poor people, who rely on natural resources more than the rich, deplete natural
resources faster as they have no real prospects of gaining access to other types of resources. Poorer people,
who cannot meet their subsistence needs through purchase, are forced to use common property resources
such as forests for food and fuel, pastures for fodder, and ponds and rivers for water (Ray S. and Ray I.
2011). Moreover degraded environment can accelerate the process of impoverishment, again because the
poor depend directly on natural assets. It also contributes to environmental degradation through over
exploitation of natural land resource.
5.9 Energy crisis
Crisis of energy is a global problem today. As the price of oil rises bio-fuel is used as an alternative source
of fossil fuel. Bio-fuel is produced from agricultural produce like oil seeds, food grains. Apart from this
food products are also used for extracting ethanol. The US utilized 20% of its corn in the year 2007 to 32%
by the year 2016 to produce ethanol. As the price of crude oil raised the US has set a target for producing
25 billion gallons of bio-fuel in the next 10 years and Europe has set a target of 5.75% of its diesel needs
extracting from plants 2011. The China is extracting ethanol not only from corn but even from rice and
wheat. These tendencies of the developed countries are the main responsible for food crisis. This change in
agricultural pattern from food production to commercial crop production has a negative effect on land
degradation. Because to earn more profit more fertile land are used for commercial purposes using modern
techniques of production and chemical fertilizers which deteriorated the quality of land, reduced forest area
and cultivable land for food production and finally the quality of land must be lost.
6. Policy Implication
To simplify the whole analysis we first consider the following static equation-
Lt = L1t + L2t -µLt
Where Lt = total supply of land in period t
L1t = land available for agricultural production (food crops + commercial crops)
L2t = land used for other than agriculture
µ = the fraction of land degraded per year, µ<1

As population increases more land should be brought under cultivation for the production of food to feed
the people and to avoid mal-nutrition, hunger, poverty i.e. food crisis. By means of intensive cultivation,
using innovative techniques and using chemical fertilizers and pesticides food production can be raised up
to a certain limit. After this the law of diminishing returns to scale on a fixed supply of land operates and
also the land lost its quality. We know that the mineral oil is the main source of energy supply. But this is an
exhaustible resource and after a long period this resource will not be available. Due to this scarcity the oil
price is rising day by day. As an alternative source of energy some lands are used for commercial purposes
to produce bio-fuels. As Lt is fixed in supply, if we want to produce more food we must have to surrender
other crop. But we want to need both and hence there is a policy dilemma.
Now we consider about L2t which is used mainly for industry, urbanization, roads, buildings, meadows,
pastures and grazing lands. Again as population raises the demand for manufacturing products increases
and many industries are established even in a fertile land. Due to rapid urbanization land is used for making
buildings, roads, educational institutions, hospitals, perks etc. Deforestation is made in a massive scale and
the common pasture and grazing lands are in the dilemma of the tragedy of commons and finally the quality
of land must be deteriorated.
The final parameter µ is also increasing by means of environmental pollution, emission of GHGs, global
warming, climate change, melting glaciers, rising sea level, soil erosion, water-runoff, floods, silting,
deforestation, use of chemical fertilizers and pesticides etc. The ultimate result is that land is degraded day
by day due to environmental pollution and its control is not in the hands of the commons and the total
supply of land is decreasing. But our objective is to minimize it. For example, to avert the tragedy of the
common village grazing land should use in a co-operative manner of the co-user.
When we consider sustainability of land use time t is very important. By sustainable land use we mean land
use not only for the present but also for the future generations. So for dynamic sustainability we must take
into account not only in period t but also in period t+1.
As a social point of view a cost must be counted that land user who is degrading the land. To neutralize the
degrading factors of land the value of land may be calculated as: NVL = VL –EC, where NVL =Net Value
of Land, VL =Value of Land and EC = Environmental Degradation Cost. But unfortunately, the NVL is
decreasing both in quality and quantity due to the mismanagement of land and failure of both stakeholders
and government policies.
All these problems are not independent to each other rather they are complementary in nature. So we must
control all these factors simultaneously. All the stakeholders must be aware about this fact. Each
government of the world should take policy united to solve these problems by means of SLM.
7. Conclusion
From the very beginning of the society land was not a problem at all. But due to the course of time as
population grow rapidly all ill hazards like environmet pollution, global warming, food crisis, povety,
unemployment, mal-nutrition, deforestation, water scarcity, soil erossion, use of chemical fertilizers and
pesticides etc are focus into the picture. Al these facors more or less directly affect the pressure upon land and
µ is increasing. All these problems cannot be solved unless the growth of population is checked. The modern
society faced the dilemma problem of population growth and for sustainable land use. Land resource is not
properly incorporated in national income accounting. When land is degraded natural resource accounting
should take place to protect this common property resource. The only way out is the SLM through which the
fixed supply of land can be used in different alternatives in a sustainable eco-friendly manner. This would
involve improved land use policies, application of environmentally feasible and viable technologies,
desertification and proper management of natural resources both at the stakeholders and government level. If
we cannot make SLM successfully the human society will not exist so long.
