collectively known as land degradation. Land degradation leads to the reduction or loss of the biological or economic productivity and complexity of land. In drylands, land degradation is known as desertification. It is estimated that % of drylands are already degraded, with over million people. In the same week, International Organization for Migration (IOM) reported that the negative impacts of climate change and land degradation are very visible in the Horn of Africa. This region consists mainly of dry land. The presence of frequent and severe droughts in the last few years damaged the area and made large parts of land likely to.

Land Degradation. Land degradation is defined as the temporary or permanent decline in the productive capacity of the land, and the diminution of the productive potential, including its major land uses (e.g., rain-fed arable, irrigation, forests), its farming systems (e.g., smallholder subsistence), and its value as an economic resource.
Land degradation and migration in a dry land region in India: extent, nature and determinants. Author(s): Amita Shah. Author Affiliation: Gujarat Institute of Development Research, Gota, AhmedabadGujarat, India.
Author Email: [email protected] by: Jonathan Davies, in Land Restoration, Abstract. Land degradation is a global challenge that affects everybody through food insecurity and higher food prices, through climate change and environmental hazards, and through the loss of biodiversity and ecosystem services.
Although there is a link between land degradation and conflict, we should be careful not to blame the victims. The book explores the myriad ways that human activity can degradation the functionality of an area of land. Typically, this area is used to grow food.
The authors point out that the subject is probably as old as history. The book also discusses non-human initiated ways that land might degrade. As by volcanic activity, for by: Land is a vital resource to humankind, like air and water.
Land degradation—the deterioration or loss of the productive capacity of the soils for present and future—is a global challenge that affects everyone through food insecurity, higher food prices, climate change, environmental hazards, and the loss of biodiversity and ecosystem services.

Name of Paper: Land Degradation and Migration in a Dryland Region in India: Understanding the Dynamics, by Amita Shah, SANDEE Working Paper No. 10 Abstract: Migration literature has always considered environmental constraints as one of the prime movers of populations, especially from dry regions, where water rather than land is the.
Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires.
Land degradation leads to the reduction or loss of the biological or economic productivity and complexity of land. In drylands, land degradation is known as desertification. It is estimated that % of drylands are already degraded, with over million people directly affected and about one billion people in over one hundred countries at risk.

Capacity of the ecosystem to provide services Size: KB. An estimated billion people, or a quarter of the world’s population, depend directly on land that is being degraded.
The consequences of land degradation include reduced productivity, migration, food insecurity, damage to basic resources and ecosystems, and loss of biodiversity through changes to habitats at both species and genetic levels.
Land Degradation Causes $10 Billion Loss to South Asia Annually South Asian countries lose billions of dollars due to soil erosion and other forms of land degradation. When land is degraded there can be serious effects such as erosion, loss of soil fertility, reduced crop yields, flooding and water shortages.

Less vegetation cover. ADVERTISEMENTS: 3. Changes in the characteristic of soil. Pollution of water resources from the contamination of. State of agriculture: Land degradation. What is land desertification. Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife.
It is caused by a variety of factors, such as climate change and human activities. This book contains selected contributions from the Sixth Meeting of the International Geographical Union's Commission on Land Degradation and Desertification, held in Perth, Australia, in September Collectively, these contributions explicitly seek to understand not only the mechanisms responsible for the problem of land degradation but their social and economic implications, the means of.
Land degradation definition: refers to human practices and technologies that extract or degrade the land's resources faster than they can be replenished and thus fail to ensure the long-term sustainability of the land. Causes of land degradation. Land degradation is a process in which the value of the physical environment is affected by a.
This report assumes prominence towards forming an action plan to combating desertification since India intends to achieve neutral land degradation status by In terms of area under the threat of desertification and land degradation compared to the total area.
and land degradation are also occurring. The condition of the soil is one of the best indicators of land degradation. The soil integrates a variety of important processes involving vegetation growth, overland flow of water, infiltration, land use and land management.
Soil degradation is, in itself, an indicator of land degradation. But, in the File Size: KB. Under the UNCCD "land degradation" means reduction or loss, in arid, semi-arid and dry sub-humid areas, of the biological or economic productivity and complexity of rainfed cropland, irrigated cropland, or range, pasture, forest and woodlands resulting from land uses or from a process or combination of processes, including processes arising.
Land degradation which is caused by multiple forces—extreme weather conditions and anthropogenic activities that pollute or degrade the quality of soils and land utility—negatively affects food production, livelihoods, and the provision of other ecosystem goods and services.
Land degradation can also lead to climate change and affect human health. The problem is more Cited by: 1. UNESCO – EOLSS SAMPLE CHAPTERS LAND USE, LAND COVER AND SOIL SCIENCES – Vol.

One of the consequences of desertification and land degradation is migration. At the same time, there is a trapped population — people not in a position to migrate during environmental stress, according to a report tabled at the ongoing 14the Conference of Parties to the United Nations Convention to Combat Desertification (UNCCD).
Land degradation can be defined in several ways depending upon the subject that needs to be emphasized. A general definition of land degradation is presented by Wasson () as: "Land degradation is a change to land that makes it less useful for human beings".
A more specific definition states that "land degradation is. compute the land degradation and anthropogenic factors of land degradation.
