The study was done at 45 different farm lands to determine the present state of the soil or land, cause and effect relationship and the soil property that was highly degraded.

Land degradation is any change in the condition of the land which reduces its productive potential. This includes the loss of topsoil, the loss of vegetation and increasing soil salinity. The degradation of agricultural and pastoral land in Australia is a matter of considerable concern. Humans interact with the world around us every day, but some of our actions are more harmful than others. As our population approaches 7 billion people, the effects of human activities on the ecosystem, including the water, air, land and the life that we share the world with, are almost immeasurable.

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.

Human-Induced Land Degradation. Land degradation involves change in the properties of land and soil (texture, color, grain size) and its functions (water holding capacity, infiltration, supporting plant life). More often than not, the changes are negative. Land degradation causes land and soil process to stop completely or function in a stunted way., Some of environmental degradation types are fossil fuel burning, waste disposal and deforestation.

Human-induced land degradation in the Emirate of Abu Dhabi is of many kinds, including salinization in agricultural farms, soil compaction by off-road 4.6 Land degradation and migration in China 17 4.7 Dams, mega-disasters, and displacement 18 4.8 Indirect impacts of land degradation on urban ecological decline and migration 19 4.9 Drought, land degradation, migration, and violent conflict 19 4.10 Out-migration as a cause of land degradation 19 5.

    2. Underlying reasons for land degradation in calabar south. The study was done at 45 different farm lands to determine the present state of the soil or land, cause and effect relationship and the soil property that was highly degraded. 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 …

    Desertification, a phenomenon referring to land degradation in arid, semi-arid and dry sub-humid regions as a result of climatic variations and human activities, is considered as one of the most severe environmental and socio-economic problems of recent times. The principal aim of this study was to explore the impacts of desertification GEO4: Chapter 3 Land (2007) [pdf 1.52Mb] Addresses the land issues identified by UNEP regional groups, and highlights the pressures of human demands on the land resource as the cause of land degradation. The health impacts of desertification and drought [pdf, 1.3 Mb] Review. UNCCD Newsletter, no. 14, pages 4 …

    WATER RESOURCES MANAGEMENT – Vol. I - Land Degradation and Desertification: History, Nature, Causes, Consequences, and Solutions - Conacher, Arthur ©Encyclopedia of Life Support Systems (EOLSS) The early initiation and growth of urban civilizations in Mesopotamia in the later part of Land degradation is “the reduction or loss of the biological or economic productivity and complexity of rainfed cropland, irrigated cropland, or rangeland, pasture, forest and woodlands resulting from land uses or from a process or combination of processes, including processes arising from human activities and habitation patterns, such as: (i

    Deforestation has been practiced by humans for tens of thousands of years before the beginnings of civilization [3]. Fire was the first tool that allowed humans to modify the landscape [4]. It is used to convert closed forests into more open ecosystems favorable to grazing land and crop cultivation. 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.

    It is often easier to identify the systemic cause of local or point land degradation processes and the most appropriate agricultural solution, than it is for diffuse processes such as organic matter decline and water pollution; and the range of limitations of agricultural solutions provide barriers to effective uptake. Deforestation has been practiced by humans for tens of thousands of years before the beginnings of civilization [3]. Fire was the first tool that allowed humans to modify the landscape [4]. It is used to convert closed forests into more open ecosystems favorable to grazing land and crop cultivation.

    MYTH 9 : Poverty is a major cause of environmental degradation Many international reports claim that poverty is a major cause of environmental delivering it - including the amount of land and the quantity of energy and ecologically damaging chemicals used to do so. Some of environmental degradation types are fossil fuel burning, waste disposal and deforestation. To begin with, the burning of fossil fuels by humans is the largest source of emissions of carbon dioxide, which is one of the greenhouse gases rise into the air and contribute to global warming, which threatens the health of the oceans and the diverse organisms living there.

    Deforestation has been practiced by humans for tens of thousands of years before the beginnings of civilization [3]. Fire was the first tool that allowed humans to modify the landscape [4]. It is used to convert closed forests into more open ecosystems favorable to grazing land and crop cultivation. Although more than 90% of SA is classified as ''affected drylands'' (Hoffman et al., 1999), we do not use the term desertification here but prefer ''land degradation'' because it helps to avoid confusion with the effects of drought and focuses primarily on human impacts.

    Humans interact with the world around us every day, but some of our actions are more harmful than others. As our population approaches 7 billion people, the effects of human activities on the ecosystem, including the water, air, land and the life that we share the world with, are almost immeasurable. Although more than 90% of SA is classified as ''affected drylands'' (Hoffman et al., 1999), we do not use the term desertification here but prefer ''land degradation'' because it helps to avoid confusion with the effects of drought and focuses primarily on human impacts.

Environmentalists, the world over, are trying their best to save the environment. On our part, we need to do our bit to make sure that they succeed. The need of the hour is to identify the causes of environmental degradation and eliminate them one by one.
