Recently there has been a dramatic increase in the area used for small scale irrigated agriculture. This study presents an analysis of the feasibility of irrigated agriculture whithout a depletion of the natural resources in the area. The analysis
involves an assessment of the quality of the potential irrigation waters and an estimation of the minimum leaching requirements to control salinity, sodicity and permeability hazards. This information and estimated crop water requirements for maize are used

Total dry matter productivity, transpiration rate and their ratio, called water use efficiency, WUE, of 6-month-old potted seedlings of 4 dryland Acacia species were compared under irrigation in Baringo. Genetic variation in water use was measured
Factors limiting productivity of overgrazed, semi-arid rangelands on the Njemps Flats, Kenya were investigated, conducting fertilization and irrigation experiments. Productivity was evaluated in terms of yield, vegetation quality and soil chemical
Water supply from the reservoir has transformed land use patterns on the Njemps Flats, providing for irrigated vegetable and cereal cultivation. No reliable sediment yield estimates were available prior to dam construction. This paper is based
. The results suggest that agroforestery under saline irrigation should favour salt tolerant species preferring ammonium-N to nitrate-N as a N source. Ammonium production was unaffected by salinity levels suggesting that oorganic mulch incorporation may buffer
