One of the causes of land degradation includes water erosion‚ the most widespread type of land degradation affecting Australia. impact of this issue - how does this issue impact on the environment Water erosion involves the removal of soil particles by water erosion‚ losing great amounts of soil where the vegetation cover is thinnest. Plant roods bind the soil‚ while leaves protect it from the impact of heavy

nourishment. Beach nourishment is a common method used by many countries‚ including Singapore and the United States‚ among other influential countries. Its main objective is to import sediment and replenish materials lost through longshore drift and erosion from destructive waves‚ and is one of the more popular soft coastal management systems worldwide. This is usually done on a large scale‚ and extends the beach seawards‚ usually by close to a kilometre‚ depending on the local environment or necessity

Causes Consequences Solutions Soil Erosion Water‚ wind‚ and people. (Miller‚2005 p.279) ●Soil erosion has two major harmful effects. One is loss of soil fertility through depletion of plant nutrients in topsoil. The other harmful effect occurs when eroded soil ends up as sediment in nearby surface waters‚ where it can pollute

with erosion‚ however‚ every method comes with disadvantages. One way in which soft engineering working well with the natural environment and is also effective‚ is beach nourishment. This is where materials such as sand and shingle are moved from the bed out at sea or further down the coast and placed at the location of the eroding beach‚ this therefore creates a wider beach. Wider beaches absorb the energy of the waves before they can create damage to the coast‚ as they reduce the erosion of the

lower course? In the upper course of a river valley‚ vertical erosion is dominant. This makes the valley shallower than in the lower course. In the lower course of the river valley‚ lateral erosion is denominate. This makes the valleys much wider than the upper course.

Conservation The issues of land distribution and land conservation in agriculture attract more and more attention‚ especially when the expansion of cropland is hitting a limit since much more land is conserved for environmental purposes. Soil erosion is devastating the topsoil of land as chemical fertilizers are used to increase output within a limited amount of land. At the same time‚ livestock production expands at an ever-growing speed‚ worsening the land use situation. Livestock production

Environmental problems Of all the global environmental problems‚ desertification is‚ perhaps‚ the most threatening for poor rural people. The most accepted definition of desertification states that it is land degradation in arid‚ semiarid‚ and dry sub-humid areas resulting from various factors‚ including climatic variations and human activities. Drylands cover almost 40 percent of the total land surface of the world and are inhabited by approximately 1 billion humans dispersed over more than 100
