Arid and semi-arid lands: Problems and prospects

 · Degradation of land productivity Deterioration of soil fertility due to increased salinity and/or alkalinity is a widespread problem in arid and semi-arid irrigated lands. The sources of salinization include wind-borne salts from adjacent deserts or salt marsh areas and the improper use of brackish water from surface or underground sources.

Kenya

Over 80% of Kenya''s lands are classified as arid and semi-arid (ASAL), based on the relatively low amounts of annual rainfall received. Often marginalised, and with high rates of poverty, the 16 million people residing in these areas (~30% of Kenya''s population) earn their living principally through a mix of pastoralism and small-scale agriculture.
