  Erosion is a serious threat, he noted, because the loss of fertile soil often is accompanied by a decrease in food production. According to one recent study, soil erosion is a global problem that has caused widespread damage to agriculture and animal husbandry, placing about billion people at risk of famine. Incorporating Social Aspects in City and Regional Planning to Cope with Flooding and Soil Erosion, in Kenya Prof. Dr. Halimu Shauri1, Stanley Wechuli Wanjala2 Abstract: In the recent past, urban growth and expansion has been astronomical due to rapid population growth.

  Of course, extreme climatic and topographic conditions may enhance erosion and increase its effects (slope, climate, heavy rainfall, climate change influence on precipitations regimes, presence of bare soil or incoherent material). DG: Soil erosion is due to different factors. The anthropic influence, however, may result as a critical factor especially in areas lacking a correct management . "The rain has decreased and where there used to be so much there is so little," says Hamidoune. His stories about the farming of yesteryear make Hamid want to live in the past.

  Trend analyses use monthly rainfall totals and the number of rain days in each month. No simple trends were found. The daily data were then processed to examine important rain dependent aspects of crop production such as the date of the start of the rains and the risk of a long dry spell, both following planting and around by:   Climate model simulations also suggest that rainfall, when it does occur, will be more intense for almost the entire world, potentially increasing the risks of soil erosion. Projections indicate that most of the world will see a % increase in heavy precipitation intensity by

According to Yang et al. (), the global average soil erosion is projected to increase approximately 9% by due to climate changes. Although soil erosion is a natural and inevitable process, the accelerated rates of soil loss, caused by the factors mentioned above, represent a serious environmental by: Expected Climate Change Impacts on Soil Erosion Rates: A Review Article (PDF Available) in Journal of Soil and Water Conservation 59(1) January with 4, Reads How we measure 'reads'.

A detailed study of storm characteristics showed that relationship between soil loss and rainfall intensities can be characterized by two forms of function: (1) in low rainfall intensities a linear function is fitted to soil loss-rainfall intensity, and (2) in high rainfall intensities nonlinear functions are fitted to soil loss-rainfall by: change, RUSLE, Actual soil erosion risk.

INTRODUCTION. Globally soil erosion is one of the global environmental problems resulting in both on-site and off-site effects on catchments. Soil erosion, defined as the detachment, transportation and deposition of soil particles by wind or water, is a natural process driven by physical factors [1].File Size: KB.

Soil conservation techniques for the highland areas are well developed and the conservation activities of self-help groups in Machakos District in eastern Kenya are particularly effective.

In the more arid areas, such as Turkana district in the far north-west, water harvesting is needed for. The specific objectives were: (1) to analyze the effects of land use/land cover on soil and water loss, (2) to determine the response of runoff and soil erosion to different rainfall regimes, and (3) to study the role of different land use types on soil erosion control under different rainfall by:   The loss of soil by water erosion in Kenya was some time ago estimated at 72 tons per hectare per year (de Graff ).

An even earlier study by Dregne reported a permanent reduction of soil productivity from water erosion in about 20 % of the Kenyan territory. Soil erosion is often manifest on the slopes near water streams, riparian areas, and Cited by: 4.

Four factors and their interrelations have long been considered the basic determiners of the rate of rainfall erosion. They are: (1) climate, largely rainfall and temperature; (2) soil, its inherent resistance to dispersion and its water intake and transmission rates; (3) topography, particularly steepness and length of slope; and (4) plant couer, either living or the residues of dead vegetation.

Under global warming, storm events tend to intensify, particularly in monsoon-affected regions. As an important agricultural area in China, the purple soil region in the Sichuan Basin, where it has a prevailing monsoon climate, is threatened by serious soil erosion.

Soil erosion results in soil fertility decline mainly because the eroded surface soil is richer in plant nutrients and organic matter than the remaining subsoil.
