“…According to Lal (1997), one of the key conditions to increase soil productivity in the sub-Saharan zone is to ensure effective water infiltration and storage in the soil. In the last two decades, several water-harvesting technologies such as tillage, stone rows, hedgerows, earth bunds and dikes have been used to improve soil water infiltration and storage (Nicou and Charreau 1985;Perez et al 1998;Zougmoré et al 2000b). Moreover, alleviating erosion-induced loss will require the development and adoption of land use systems that are capable of replenishing or maintaining the nutrient status of the soil in addition to controlling water runoff and soil erosion (Sanchez et al 1997;Quansah and Ampontuah 1999).…”

The synergistic effect of soil and water conservation (SWC) measures (stone rows or grass strips) and nutrient inputs (organic or mineral nutrient sources) was studied at Saria station, Burkina Faso. The reduction in runoff was 59% in plots with barriers alone, but reached 67% in plots with barriers + mineral N and 84% in plots with barriers + organic N, as compared with the control plots. Plots with no SWC measure lost huge amounts of soil (3 t ha -1 ) and nutrients. Annual losses from eroded sediments and runoff reached 84 kg OC ha -1 , 16.5 kg N ha -1 , 2 kg P ha -1 , and 1.5 kg K ha -1 in the control plots. The application of compost led to the reduction of total soil loss by 52% in plots without barriers and 79% in plots with stone rows as compared to the losses in control plots. SWC measures without N input did not significantly increase sorghum yield. Application of compost or manure in combination with SWC measures increased sorghum grain yield by about 142% compared to a 65% increase due to mineral fertilizers. Yields increase did not cover annual costs of single SWC measures while application of single compost or urea was cost effective. The combination of SWC measures with application of compost resulted in financial gains of 145,000 to 180,000 FCFA ha -1 year -1 under adequate rainfall condition. Without nutrient inputs, SWC measures hardly affected sorghum yields, and without SWC, fertilizer inputs also had little effect. However, combining SWC and nutrient management caused an increase in sorghum yield.

The problem of shortage of water to crops can be resolved by increasing total water supply available to plants, increasing water use relative to other losses and efficient management of scarce water. Biophysically, solutions to many of the problems will require the improvement of soil, water, and crop management at the field, plot, and farm level: first, to increase the capture and retention of incoming (rain) water; and second, to maximize the proportion of that water productively transpired by the crop. Dry land agriculture under rain fed conditions is found mainly in Africa, the Middle East, Asia, and Latin America. In the harsh environments of Sub-Saharan Africa (SSA) and West Asia and North Africa (WANA), water is the principal factor limiting crop yield. A review has been carried out on soil and crop management research that can increase the water use efficiency. The WANA production systems are dominated by cereals, primarily wheat in the wetter and barley in the drier areas, in rotation with mainly food legumes such as chickpea, lentil and forage legumes. The SSA production systems are generally characterized by cereal/legume mixed-cropping dominated by maize, millet, sorghum, and wheat. The major constraints in both regions to crop production are low soil fertility, insecure rainfall, and low-productive genotypes, low adoption of improved soil and crop management practices, and lack of appropriate institutional support. Different cropping systems and accompanying technologies are discussed. Results indicate that there is an advantage to apply these technologies but being function of socio-economic and bio-physical conditions. It is recommended that future research focuses on integrated technology development while taking into account also different levels of scale such as field, village, and watershed.

Dryland agriculture under rainfed conditions is found mainly in Africa, the Middle East, Asia, and Latin America. In the harsh environments of Sub-Saharan Africa (SSA) and West Asia and North Africa (WANA), water is the principal factor limiting crop yield. A review has been carried out on soil and crop management research that can increase the water use efficiency. The WANA production systems are dominated by cereals, primarily wheat in the wetter and barley in the drier areas, in rotation with mainly food legumes such as chickpea, lentil and forage legumes. The SSA production systems are generally characterized by cereal! legume mixed-cropping dominated by maize, millet, sorghum, and wheat. The major constraints in both regions to crop production are low soil fertility, insecure rainfall, low-productive genotypes, low adoption of improved soil and crop management practices, and lack of appropriate institutional support. Different cropping systems and accompanying technologies are discussed as well as selected examples of impact of these technologies. Results indicate that there is an advantage to apply these technologies but being function of socioeconomic and bio-physical conditions. It is recommended that future research focuses on integrated technology development while taking into account also different levels of scale such as field, village, and watershed.
