Correct estimation of soil loss at catchment level helps the land and water resources planners to identify priority areas for soil conservation measures. Soil erosion is one of the major hazards affected by the climate change, particularly the increasing intensity of rainfall resulted in increasing erosion, apart from other factors like landuse change. Changes in climate have an adverse effect with increasing rainfall. It has caused increasing concern for modeling the future rainfall and projecting future soil erosion.

Urbanization is occurring at an unprecedented rate, particularly in developing countries, with high migration of population from rural to urban areas. As a consequence of urbanization and associated environmental impacts, the issue of providing water to growing urban population is becoming critical. Water management in the context of urban area has two components i.e.

This paper compares the widely used three irrigation systems, viz., drip, sprinkler and furrow, using the data observed in a laboratory farm located in the semi-arid region of Kenya. For these irrigation systems, the total irrigation requirements were 479.50, 610.55 and 783.50 respectively, but with same 428.95 mm of net irrigation requirement (NIR). The respective application efficiencies for the three systems were 89.72%, 70.31 and 54.54% indicating the drip irrigation system to be more efficient than the others in this study.
