Abstract: Abstract In many developing countries, yield increases obtained through intensification of agriculture seems necessary to face the high population growth rate. In the case of rainfed agriculture of semiarid regions the effect on yield of some intensive farming practices is highly variable, however, due to interactions with rainfall distribution and amount. This paper presents a model (SARRA) to perform regional comparisons of the risk associated with intensive practices in semiarid environments. The model, built for this specific and restricted...
