Essay on Land Degradation and its Cause! Land degradation is a concept in which the value of the biophysical environment is affected by one or more combination of human-induced processes acting upon the land. Natural hazards are excluded as a cause; however human activities can indirectly affect phenomena such as floods and bushfires.
Under this reason the land degradation is caused due to continuous and long-term removal of soil mass and nutrients from the land by the action of water.In detail, overgrazing represented the primary cause of land degradation at more than a third followed by deforestation and over-cultivation which accounted for approximately 30% of land degradation. The remaining proportion was for unspecified causes at 7%. On the other hand, causes of land damage varied significantly between the regions.The major causes are land clearance such as clear cutting and deforestation, agriculture activities, irrigation salinity and over drafting, livestock including overgrazing, pollution and industrialization. Overgrazing is a common problem in many parts of Australia.
Read this article to learn about the meaning, factors responsible, prevention and control measures of land degradation: The change in the characteristic and quality of soil which adversely affect its fertility is called as Degradation. Land degradation is the major consequences of direct interference of human activities in the natural phenomenon.
A further 28% of global degradation is due to over-cultivation of crops. Other causes account for only 7% collectively. These causes affected different regions differently in the 1990s, with Europe having as much as 9.8% of degradation due to deforestation, while the impact of this on Oceania and North America was minimal, with only 1.7% and 0.2% of land affected respectively.
The pie chart shows the main causes of the global land degradation and their proportion while the table illustrates what consequences these causes led to in North America, Europe and Oceania in 1990s. As we can see from the pie chart, the main cause of the land degradation is over-grazing, which result in 30% degradation land.
Essay on Desertification (620 Words) Article shared by Desertification means a process of degradation of the environment that usually is a product of climate and human activity and involves the spread or extension of desert-like conditions in a hitherto fertile area.
Included: environment essay cause and effect essay india essay content. Preview text: Land, a non-renewable resource, is central to all primary production systems. Over the years, the country's landmass has suffered from different types of degradations. Degradation of land is caused by biotic and abiotic pressures. An ever-increasing.
The causes of land degradation can be divided into natural hazards, direct causes, and underlying causes. Natural hazards are the conditions of the physical environment which lead to the existence of a high degradation hazard, for example steep slopes as a hazard for water erosion.
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.
Thermal and heat pollution is a cause of greenhouse effect and global warming. All these pollution types affect the non-living and living. In land degradation section papers from Sri Lanka.
Cause And Effects Of Land Degradation Environmental Sciences Essay. Land degradation is an issue of increasing concern to most countries. It is a concept in which the value of the environment is affected by one or more combination of human induced processes acting upon the land.
Environmental degradation is the exhaustion of the world's natural resources: land, air, water, soil, etc. It occurs due to crimes committed by humans against nature. Individuals are disposing of wastes that pollute the environment at rates exceeding the wastes’ rate of decomposition or dissipation and are overusing the renewable resources.
There are six major causes of land degradation in Calabar South, they include; deforestation, shortage of land due to increased populations, poor land use, insecure land tenure, inappropriate land management practices and poverty, problems of valuation, and even of assigning causality, make it impossible to compute accurate benefit-cost ratios for reducing land degradation.
In this study, therefore, desertification is equivalent to land degradation in the dry zone, and need not be separately assessed as a type of degradation. Other types Of degradation included Other types of land degradation are treated briefly, treated as causes, or excluded from this review.
Land Degradation A major portion of the Earth’s ice-free land area is subject to human-induced degradation leading to soil erosion from agricultural fields with an estimated level of 10 to 20 times to more than 100 times higher than the soil formation rate Climate change exacerbates land degradation, particularly in low-lying coastal areas, river deltas, drylands and in permafrost areas.
Many international reports claim that poverty is a major cause of environmental degradation, including the World Commission on Environment and Development’s report, Our Common Future 70 and UNEP’s Geo 2000.71 There is very little evidence that this is actually the case on a global scale either in rural areas72 or in urban areas.
