[Downdrift erosion is a common feature of shores occurring where a headland, inlet, river, bay, canyon, reef or shoal blocks the natural longshore drift of materials, that is transport of sand and gravel by waves and currents. Sediment transport results in accumulations on updrift or receiving side and in the adjoining ocean. There is a corresponding depletion of materials on the downdrift side. The terminology "Littoral Drift Barrier" is accordingly developed. This paper is "an interim report" which reviews practical cases of leeside erosion and attempts to explain the development as a function of time.]

This causes the soil to be much more easily eroded, which leads to the degradation of the land in Kenya. Other environmental conditions causing erosion are hillslope gradient, and ground cover; the ground cover si heavily affected by the climate and grazing. Since the over-harvesting of trees ahs caused erosion fo the soil, the land is now much less fertile, and therfore less likely to produce more trees. The implementation of zero tillage agriculture on these soils will lead to increased production of woody biomass and increase the nutrient store for the tropical ecosystems.]

[Sedimentation and erosion are processes that happen naturally and that, over time, have shaped the physical features of the earth. Human activities can have a negative effect on the way sedimentation and erosion occur. Such human activities include the building of dams, channelization of rivers, dredging of stream beds, grazing, and logging. While these activities can have a negative effect if left unchecked, they can also be good things if correctly implemented.]

Bad farming techniques, deforestation, and an increasing population are all reasons for this major problem. Since the farmers in Ethiopia are using techniques that disturb the environment and use up the nutrients of the soil they are forced to move to different fields and cultivate more land. Farming education and proper land management that takes into account the whole ecosystem will be valuable for Ethiopia, because it will reduce land degradation.]

A lot of grazign causes soil erosion and land degradation because the animals remove the vegetation which anchors the soil, which makes it more easily removed by wind and water. The major reason why areas are becoming overgrazed is because people do not look at the ecosystem as a whole. We need to look at the relationships betweeen plants, animals,vegetation, and soils in order to find a good system of grazing that won't degrade the land.]

In the areas where there had been more grazing and cultivation the 137 Cs-radioactivity levels were lower and the organic carbon content of the soil was significantly reduced. In heavily grazed and cultivated areas the cation exchange rate were much lower, which means the soil was much less fertile.]
