Degradation of the natural environment is a worldwide problem, and some examples are quite ancient. Avoiding land degradation through sustainable land management can generate up to USD 1.4 trillion of economic benefits. Policies and programmes to halt and reverse land degradation have long suffered from the absence of a clear overarching goal and quantitative, time-bound targets to guide action and make measurable progress. There are four main ways of looking at land degradation and its impact on the environment around it: A problem with defining land degradation is that what one group of people might view as degradation, others might view as a benefit or opportunity. In this report, land degradation is defined as a negative trend 4 in land condition, caused by direct or indirect human-induced processes including anthropogenic degradation synonyms, degradation pronunciation, degradation translation, English dictionary definition of degradation. In proper terminological definition, forest degradation is the decline of the capacity of a forest to produce healthy ecosystem products and services such as the provision of timber and other resources, support to biodiversity, carbon storage and so on as a result of environmental and anthropogenic changes. Another word for degradation. Policies and programmes to halt and reverse land degradation have long suffered from the absence of a clear overarching goal and quantitative, time-bound targets to guide action and make measurable progress. The most important, according to the EEA (1998), is soil contamination. Hence shrinking of the land resource base is a big problem before developing country like India. Land degradation is the temporary or permanent lowering of the productive capacity of land (UNEP, 1992b). Some information for local and regional scales is available and has been reviewed by Lal (1998). It is a significant factor in Afghanistan. A general definition of land degradation is presented by Wasson (1987) as: "Land degradation is a change to land that makes it less useful for human beings". Some types of degradation include salinification and acidification of soils, topsoil loss, soil compaction , and pollution of land that makes it unusable. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. This is considered to be an important topic of the 21st century due to the implications land degradation has upon agricultural productivity, the environment, and its effects on food security. As the land resource base becomes less productive, food security is compromised and competition for dwindling resources increases, the seeds of famine and potential conflict are sown. As a result of sea-level rise from climate change, salinity levels can reach levels where agriculture becomes impossible in very low-lying areas. Also, environmental degradation aspects such as deforestation and mining destroy the natural land cover. Land degradation can go fast, as can be the case of deforestation or forest fires, but often land degradation is a very slow process. For example, planting crops at a location with heavy rainfall and steep slopes would create scientific and environmental concern regarding the risk of soil erosion by water, yet farmers could view the location as a favourable one for high crop yields. , The United Nations Sustainable Development Goal 15 has a target to restore degraded land and soil and achieve a land degradation-neutral world by 2030.. A decline to a lower condition, quality, or level. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable. Land degradation means loss in the capacity of a given land to support the growth of useful plants on a sustained basis. Learn more. But just what is the meaning of land pollution? , In addition to the usual types of land degradation that have been known for centuries (water, wind and mechanical erosion, physical, chemical and biological degradation), four other types have emerged in the last 50 years:. Usually land degrad ation is described in terms of the loss How to use degradation in a sentence. Yet slow but continued degradation can lead to virtually in reversible losses of resources from the ecosystem and the land will degrade beyond self-repair or what we call destroyed or collapsed system. It can be prevented by formation of ridge and furrow during irrigation which lessens run off. 2 Land degradation affects people and ecosystems throughout the planet and is both affected by 3 climate change and contributes to it. Resilience is the ability of a landscape to absorb change, without significantly altering the relationship between the relative importance and numbers of individuals and species that compose the community. Changes in climatic conditions because of unbalanced created in the environment. Johnson, P. Lamb, M. Saul, and A.E. Definition: Land degradation is the reduction or loss of the biological or economic productivity and complexity of rain—fed cropland, irrigated cropland, or range, pasture, forest or woodlands resulting from natural processes, land uses or other human activities and habitation patterns such as land contamination, soil erosion and the destruction of the vegetation cover. What is land degradation? This usually checks or reduces the velocity of run off so that soil support vegetation. The economic impact of land degradation is extremely severe in densely populated South Asia, and sub-Saharan Africa. 4. A form of land degradation associated with the coast is acid sulfate soils. However, there is no single internationally-approved definition of “degraded land”. It is one of the agricultural practice in which different crops are grown in same area following a rotation system which helps in replenishment of the soil. Other dryland regions have also experienced desertification. High population density is not always related to land degradation. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires. [technical] There are serious problems of land degradation in some arid zones. Soils are a fundamental natural resource, and are the basis for all terrestrial life. Desertification & Land Degradation.  Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bush fires. Deserts, semi-arid lands, and dry woodlands also constitute a large potential source of carbon emissions into the atmosphere. Less vegetation cover Degradation is an important word in terms of environmentalism because it can be used to describe so many detrimental environmental conditions. Overall, more than 36 types of land degradation can be assessed. However, there is no single internationally-approved definition of “degraded land”. degradation definition: 1. the process in which the beauty or quality of something is destroyed or spoiled: 2. the…. This can be measured from a base line of past land use. Land degradation. Video shows what land degradation means. For reasons outlined above, poor farmers are led to clear forest, cultivate steep slopes without conservation, overgraze rangelands, make unbalanced fertilizer applications, and the other causes noted above. It is a serious environmental problem. When these normally waterlogged soils are exposed to air by drainage or drought, the iron sulphides oxidise produc- en * We recognize that actions to reduce emissions, including from deforestation and forest degradation, and to increase removals by sinks in the land use, land use change, and forestry sector, including cooperation on tackling forest fires, can make a contribution to stabilizing greenhouse gases …  It is estimated that up to 40% of the world's agricultural land is seriously degraded. 5. Image Courtesy : en.wikipedia.org/wiki/File:Karst_following_phosphate_mining_on_Nauru.jpg. Overgrazing is the grazing of natural pastures at stocking intensities above the livestock carrying capacity; the resulting decrease in the vegetation cover is a leading cause of wind and water erosion. 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. The result is a loss of land productivity with impacts on livelihoods and Definition Of Environmental Degradation. Title: Land Degradation 1 Land Degradation 2 Definition. Rather, it is the practices of the human population that can cause a landscape to become degraded. Land degradation can therefore be defined as the misuse of land or the deterioration in the quality of the land through excessive exploitation of the land. land degradation definition in English dictionary, land degradation meaning, synonyms, see also 'Land',Land',Adélie Land',Arnhem Land'. "Land degradation" refers to a temporary or permanent decline in the productive capacity ofthe land,2 or its potential for environmental management.3 "Land improvement" Before publishing your articles on this site, please read the following pages: 1. 2 Land degradation affects people and ecosystems throughout the planet and is both affected by 3 climate change and contributes to it. It negatively affects food production, livelihoods, and the production and provision of other ecosystem goods and services. Isaacson, D.N. A decline to a lower condition, quality, or level. 4. In 2015, about 500 (380–620) million people lived within areas which experienced desertification between the year 1980s and 2000s. This, together with air, water, and land pollution pose several atmospheric alteration threats. Land degradation is a negative change in the quality of land, usually induced by a mixture of natural and man-made causes. Land Degradation As the land use section earlier in this chapter shows, demands on the land for economic development and pressures from a burgeoning population are leading to unprecedented land use change. According to Central European University, Land degradation has different forms and causes. In Canada, for example, on-farm effects of land degradation were estimated to range from US$700 to US$915 million in 1984 (Girt, 1986). Land degradation is caused by multiple forces, including extreme weather conditions, particularly drought. Population pressure also operates through other mechanisms. Shifting ecological risk: increased vulnerability of the environment or people to destruction or crisis.
