Eastern Africa has experienced widespread land degradation over the past century. Approximately 65% of agricultural land in Kenya has become degraded, largely through overgrazing, mismanagement, and deforestation. Soil quality has declined significantly, reducing crop production across Sub-Saharan Africa, where yields have decreased over the past 20 years unlike other regions. Improving farming practices, education, environmental protection, and aid can help address this problem.

Environmental + Economic Impact Analysis
This document analyzes the environmental and economic impacts of oil production in Ecuador and tourism in the Galapagos Islands. It notes that while oil production boosted Ecuador's GDP, it has led to over 30% of the Amazon being deforested or polluted. Currently, Ecuador loses $9 per barrel of oil produced. Tourism generates $418M annually for the Galapagos but increased visitors are damaging the environment and wildlife. The conclusion is that current policies prioritize short-term economic gains over long-term environmental sustainability.
Lecture 7-2
The United States is the world's leading agricultural nation despite having less than 8% of the world's land suitable for farming and less than 3% of its population involved in agriculture. The US produces about 20% of the world's wheat, corn, oats and sorghum as well as being responsible for 14% of dairy products and 17% of meat globally. Additionally, American farmers face the challenge of overproducing food and agricultural products, which has lowered prices and caused difficulties for some farmers.
Lecture 7-2
The United States is the world's leading agricultural nation, despite a small percentage of the population being involved in farming. Agriculture is a major industry in the US, with over 2 million farms cultivating over 900 million acres. Farming is concentrated in the central Great Plains and around the Great Lakes. The US is the top global supplier of grains, dairy, meat, and soybeans, producing a disproportionate amount relative to its farm land area. However, overproduction has lowered prices and caused difficulties for some farmers.
Land care in namibia hm_v1.0
Existing Landcare programs are present across the Southern Africa Development Community (SADC) region. The most establish program is in South Africa, where a National LandCare program has been in place since 1997. Leadership from South Africa has seen the application of Landcare in trans-boundary projects, including the Kalahari Namib Project within the Molopo-Nossob River Basin across Botswana, Namibia and South Africa.
Farming During the Time In the Novel
The Dust Bowl of the 1930s devastated farmers in the Midwest plains. Years of drought and poor farming techniques stripped the soil of nutrients. As crops failed, thousands of farmers packed what few belongings they had left and migrated west to California in search of work. The journey was long and difficult, and the hardships continued even after they arrived in California, as farmers struggled to find stable work and faced prejudice.
PLAN B NO BS - A. Deathbed - Earth, ALL Creation but A final Chance Remains -...
The document warns that humanity's extinction is imminent due to accelerating environmental collapse caused by climate change, resource depletion, and pollution. Key points include glacial and ice sheet melting raising sea levels by over 6 feet this century and displacing 600 million people, as well as collapsing ecosystems, forests, fisheries, and water supplies due to market failures to incorporate environmental costs. The author argues that urgent action is needed to transition off fossil fuels and stabilize population to avoid an irreversible extermination of humanity.
Agriculture danks
This document summarizes various topics related to food resources and the impacts of agriculture. It discusses how the majority of the world's food comes from only 15 plant species and a few animal species. The major types of agriculture are described as traditional subsistence, shifting cultivation, nomadic herding, traditional intensive, plantation, and industrialized. The Green Revolution led to higher-yielding crops but also greater dependence on fossil fuels, cash economies, and introduced unintended consequences like invasive species. Environmental effects of food production include biodiversity loss, soil degradation, pollution, and impacts on human health.
Agriculture in usa
Agriculture in the US employs only 2% of the population but uses highly mechanized and productive farming techniques on 20% of US lands. US agriculture operates more like a business focused on large surpluses and profits, using immigrant and marginalized labor mainly for harvesting. The government protects US agriculture through subsidies and import restrictions to support domestic farmers' livelihoods, but this makes it difficult for other countries to compete in global markets.

Describing a farm
A farm is an area of land used primarily for agricultural purposes like producing food and crops. Farms can be specialized for different products like fruits, vegetables, dairy, pigs or poultry. Modern farms in developed countries are highly mechanized, using machines for tasks and fewer farm workers. Traditional family farms are being replaced by larger commercial operations. The transition from hunter-gatherer societies to settled, agricultural societies began over 12,000 years ago in the Middle East, marking the beginning of the Neolithic Revolution. Farms can be owned by individuals, families, corporations and range in size from small plots to thousands of hectares. Farms may focus on a single crop or have a variety and may also raise livestock.

The document discusses the importance of aggregates and farmland for agriculture. It notes that aggregates shape the geological characteristics of an area, influencing what grows and the biodiversity. Aggregates also impact water resources. The document then provides information about farmland in Ontario, noting that Ontario has the largest agricultural output in Canada despite having less farmland than other provinces. However, the number of farms and amount of farmland in Ontario has declined in recent years due to development. There is a need to protect high quality farmland and water resources to ensure future food security.
Changes in an ecosystem
The document discusses how living and non-living things can cause ecosystems to change through events like floods, volcanic eruptions, droughts and forest fires, and how these changes then affect living organisms. It also addresses how human activities such as deforestation, overpopulation and pollution can impact ecosystems, and provides examples of effects like reducing the food supply, destroying habitats, and endangering or causing extinction of species. The document concludes by recommending ways to protect ecosystems through conservation efforts and adapting to changes through strategies like protection, relocation or accommodation.
Madagascar
Madagascar is an island country located off the southeastern coast of Africa in the Indian Ocean. It has a population consisting of various ethnic groups and was formerly a French colony, gaining independence in 1960. The economy relies heavily on agriculture, fishing, and tourism, though it has experienced periods of economic instability due to political disputes and currency devaluation.
Food in the Developed World
1) Food issues in developed countries include overconsumption leading to widespread obesity and health problems, as well as a lack of knowledge about healthy food choices. This wastes resources and contributes to an unhealthy lifestyle and fast food industry.
2) The standard Western diet relies heavily on highly processed and unhealthy foods like red meat, sugar, fat and refined grains, obtaining nearly 1/3 of calories from junk food according to some reports.
3) Agricultural practices in developed nations require large amounts of fertilizers, pesticides, irrigation, land, energy and other resources which cause environmental degradation, fossil fuel dependence and lower efficiency.
Madagascar
Africa. Madagascar's culture and history were presented through a group project covering its geography, population, history, business, gender roles, clothing, and rituals. Key points include that 90% of its plants and animals evolved there, its major exports are coffee, vanilla and sugar, and while its laws allow equal pay for women traditions give men greater social and religious roles. The population's religious beliefs include indigenous traditions tied to ancestors, Christianity, and Islam.
Kilimanjaro – The Icon of Africa (SF)
- Kilimanjaro is an iconic mountain in Africa whose disappearing snowcaps symbolize the effects of climate change. Communities in the Kilimanjaro region of Tanzania have seen changes to their livelihoods over time due to various factors including climate change, socioeconomic changes, and colonial influences.
- Livelihoods traditionally involved subsistence farming and pastoralism but have diversified over time. Coffee growing was important but declined due to management issues. Rice farming has increased as a livelihood since the 1970s due to irrigation projects.
- While climate change is a factor, livelihood vulnerabilities are often exacerbated more directly by exclusion from resources and poor governance rather than climate alone. Understanding local contexts is important

Word water by glecik
This document discusses various aspects of water use for agriculture production. It provides data on the water requirements of different crops, ranging from 500-5000 kg of water needed to produce 1 kg of various foods. More efficient irrigation techniques like drip irrigation and sprinklers can improve water use efficiency and crop yields compared to traditional surface irrigation. The type of irrigation used will impact how much water is available for food production globally by 2050 when the population is projected to reach 8.9 billion people. Accounting for all factors from growing to processing to losses, significant uncertainty remains in whether food demands can be met sustainably.
17. soil land degradation by Allah Dad Khan
This document outlines the key concepts of land degradation, conservation, and rehabilitation. It begins by defining land as the solid part of the Earth's surface including the atmosphere, soil, geology, and hydrology that interact with it. Land degradation is then defined as the loss of function of the land that reduces its capacity to provide goods and services like productive land uses, environmental benefits, and social goods. The document notes degradation is typically gradual, unlike natural hazards, and is primarily caused by human activities rather than natural processes alone. It aims to discuss how land degradation is assessed and mapped as well as concepts of land conservation and rehabilitation.
Soil Degradation By Different Land Use Impacts In Tropical Rainforests
This document discusses soil degradation in tropical rainforests due to different land uses and the consequences for land rehabilitation. It finds that logging, slash-and-burn agriculture, annual crops and tree plantations can lead to decreases in biomass, soil organic matter, and plant-available nutrients as well as increases in erosion and leaching. Studies in Ecuador, Bolivia, and Ivory Coast examined changes in water and nutrient cycling from rainforest conversion to agroforestry systems like cocoa plantations. The research aimed to evaluate impacts on soils with low to medium fertility and understand how to develop sustainable production systems, especially for small farmers.
Soil Degradation in developing countries
Soil degradation is a major problem affecting developing countries. Around the world, 16% of soil has degraded, with rates as high as 75% in Central America and 20% in Africa. This level of degradation leads to an estimated 13% total crop loss over the past 50 years. Poor communities are most severely impacted by degraded soil as they rely on farming for income and are less able to improve practices. Continued soil degradation could further reduce yields and lead to increased food insecurity and malnutrition in developing nations by 2020.
LAND DEGRADATION AND CONSERVATION MEASURES
Mining activities and mineral processing can cause severe land degradation through deforestation, dust pollution, and reduced water infiltration. Afforestation, shelter belts of plants, and controlling overgrazing through good land management practices like setting appropriate stocking levels and avoiding overstocking can help mitigate degradation to some extent. Proper management of waste lands and control of mining activities is also needed.
Land or soil degradation as an environmental problem
The document is a seminar presentation on land degradation by Mwenya Mundende. It defines land degradation as the reduction in the capability of land to support particular uses. The causes of land degradation include both natural factors like climate change and human activities like deforestation and unsustainable agriculture. The effects are loss of biodiversity, decline in soil quality, increased food and water insecurity. Both international agreements like the UNCCD and national Zambian laws address land degradation. Recommendations include developing economic incentives for sustainable land use and improving land use information systems.
Degradation of ceramics
Degradation of an object occurs as a result of the interaction between the environment or with the materials that form the object however, in the case of ceramics, environmental factors are the major cause. There are several ways in which ceramics break down physically and chemically.
Land degradation-SHOBHANA
Land degradation is caused by human-induced processes like deforestation, poor farming practices, overgrazing, and mining activities that deteriorate the quality of land and resources. This leads to soil erosion, reduced nutrients and productivity, desertification, and loss of vegetation. Preventive measures include proper waste management, controlled mining, afforestation, and sustainable agricultural and grazing practices.
Land degradation and its management
This document discusses land degradation and its management. It defines land degradation as changes to soil quality that negatively impact fertility. Key points made include:
1) Over 50% of agricultural land is moderately to severely degraded, with 75 billion tons of fertile soil disappearing each year and 12 million hectares lost to drought/desertification annually.
2) Causes of land degradation include deforestation, soil erosion, mining, industrialization, unsustainable agriculture, and urban expansion.
3) Effects are declines in soil properties, water availability, biodiversity, and productivity which threaten food/water security.
4) Sustainable land management techniques like crop rotation, contour farming and bund construction can help reduce
Soil degradation
1) Soil degradation, especially from erosion, is a major threat to Indian agriculture, with over half of the country's land degraded. Erosion accounts for the loss of over 5 billion tons of soil per year.
2) The document outlines several government policies and programs aimed at preventing further soil degradation, promoting conservation, and improving water and nutrient management. It emphasizes the need for integrated approaches like wasteland development and precision irrigation.
3) Key recommendations include better mapping of degradation hazards, incentives for conservation practices, and further research on sustainable farming techniques to balance soil health and productivity over the long term.
Land Degradation And Conservation
The document discusses causes of land degradation in India and measures for land conservation. Key causes include mining, overgrazing, over-irrigation, mineral processing, and industrial effluents. Conservation measures proposed include afforestation, controlling overgrazing, stabilizing sand dunes, managing waste lands, controlling mining activities, and proper disposal of industrial waste. The goal is to discuss soil classification in the next module.

Land degradation
Land degradation refers to the reduction in soil quality and fertility due to various human and environmental factors. It is a major challenge for sustainable development. The causes of land degradation include deforestation, soil erosion, mining, unsustainable agricultural practices, and urban expansion. These activities can lead to declines in soil quality, water availability, biodiversity, and agricultural productivity. Conservation measures to prevent land degradation involve practices like strip farming, crop rotation, contour farming, and construction of bunds and ridges to reduce soil erosion. Sustainable land management aims to utilize land resources for production without reducing long-term productivity through practices informed by climate information.
Land degradation
The document discusses several key issues related to land degradation and environmental problems in Australia, including:
1) Land degradation is caused by land clearing and poor land management practices like overgrazing and excessive fertilizer and pesticide use.
2) Water erosion occurs when heavy rainfall or running water removes soil particles, washing them downhill and depositing them in waterways. The loss of vegetation cover increases water runoff and erosion.
3) Salinity is caused by high salt levels in soils and groundwater brought near the surface due to changes in vegetation cover and water flows. This damages agricultural lands and pollutes waterways.
Total catchment management, which considers all resource uses and stakeholders, is needed to
land degradation
Land degradation is the temporary or permanent lowering of land productivity caused by soil degradation, impacts on water resources, deforestation, and other factors. Key factors responsible for land degradation include loss of vegetation from deforestation, unsustainable extraction of fuel and fodder, shifting cultivation, encroachment into forests, overgrazing, failure to implement soil conservation measures, improper crop rotation, misuse of agrochemicals, poor management of irrigation systems, excessive groundwater extraction, open access to resources, and poverty among agriculture-dependent communities.

Global Agriculture Sustainability May08
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 Vertical Shift - Avoiding the Malthusian Catastrophe - Gordon Graff
The document discusses ways to avoid a Malthusian catastrophe of population growth outpacing food production through land consumption. It outlines how human agricultural land use has already claimed 38% of the earth's land area, with 80% of potentially arable land in use. To feed the additional 2.5 billion people expected by 2050 will require an area the size of Brazil. Initiatives proposed include dramatically improving land efficiency through vertical farming projects like SkyFarm, which can produce the same yield as 1,369 acres of conventional farming on only 1.34 hectares of land. These initiatives aim to avoid issues like massive starvation, irreversible ecological damage from further land clearing, and make agriculture independent of fossil fuels.

Urban farming-presentation july2008
The document discusses issues with current linear agricultural practices and land consumption, and proposes vertical farming as an alternative. Specifically:
1) Current agriculture is unsustainable due to finite land and increasing population pressures, leading to widespread deforestation and environmental degradation.
2) Vertical farming in "Sky Farm" skyscrapers is proposed as an alternative, which could grow enough food for 40,000 people using only 1.34 hectares of land instead of hundreds through highly efficient water and space use.
3) "Sky Farm" would be fossil-fuel free and could improve food security while reducing agriculture's environmental impact through waste recycling and renewable energy.
Social Implications of the Banana Trade
Some backroom and brief sociohistorical analysis of the banana industry, created for an intro to horticulture class.
World Population and Food Supply
The world population has grown exponentially from 5 million in 8000 BC to over 6 billion currently. Most population growth is occurring in poorer parts of the world. The global population increases the worldwide demand for food by 2% per year. However, the poorest countries only see a 1.9% increase in food supply to match their higher 2.5% increase in demand. Potential solutions to increasing the global food supply include improving crop yields through technology like genetic modification, expanding available farmland, and boosting food production from aquatic sources. However, simply providing technology or food to underdeveloped areas may not fully address the issues caused by rising populations and unequal access to resources.

Livestock, Landscapes and Livelihoods: the contribution of global grazing-lands to climate change mitigation and adaptation - Constance Neely
Ps hb in nature
The document discusses how human activity has come to dominate nature, with one-third of available fresh water and 20% of net terrestrial primary production now used for human purposes. It notes that climate change poses risks, with average future temperatures expected to be higher than any time in human evolution. The large human footprint on the planet indicates that Earth's biosphere may be approaching a state shift unless humanity changes its relationship with the natural world.

Deforestation
Deforestation involves the removal of forests through activities like converting forestland to farms, ranches, or urban use. It is a major problem, with forests covering over 30% of the Earth's land but providing livelihoods for over 1 billion people. The top three drivers of deforestation are shifting cultivation by poor farmers, commercial logging operations using heavy machinery, and mining, dams, and infrastructure development which damage forests and ecosystems. Deforestation significantly contributes to climate change by reducing the Earth's ability to absorb carbon dioxide from the atmosphere.

This document summarizes three major famines in history: the Ukrainian Holodomor, the Great Leap Forward in China, and the Darfur famine. It describes how Stalin's policies led to the intentional starvation of Ukrainians, how Mao's Great Leap Forward caused widespread famine through poor management and lowered food production, and how drought and conflict contributed to deaths from starvation and disease in Darfur.

1. Approximately 1.3 billion tonnes of food, worth over $100 billion, is wasted globally every year even as millions go hungry. This is enough food to feed the entire population of sub-Saharan Africa.
2. A significant amount of the water used to produce this wasted food is also wasted, as agriculture requires large amounts of water. The water wasted could meet the domestic needs of over 9 billion people.
3. Addressing food waste could help reduce greenhouse gas emissions from agriculture by over 10% in rich countries, and help alleviate pressure on freshwater resources globally. Reducing food waste is important to help solve the growing global food crisis.

The document discusses how population growth and land use impact the environment. It notes that the human population has grown rapidly since the 1800s due to advances in medicine, sanitation, and nutrition. The population is predicted to reach 9 billion by 2050. As population increases, so does resource consumption and waste production. Agriculture uses 11% of the Earth's land but farming practices like chemical usage can contaminate soil and water. Deforestation reduces forests, which impacts climate and species. Development like roads and buildings also affects the environment by increasing runoff and reducing groundwater. The large and growing human population poses challenges around whether Earth's resources can support such high demand sustainably.
