The most important source of increased crop yield in the Middle East has probably been the increase in irrigated area although it has been accompanied by other inputs such as chemical fertilizers, improved varieties, mechanization, and pesticides. Palestine, which in this paper encompasses West Bank and Gaza, has had a similar emphasis on irrigation although only 5% of West Bank agricultural land is irrigated. However, the possibility of further expanding or even maintaining present water use for fostering agricultural growth in this dry region is diminishing. There now is a growing understanding that future sustainable agriculture in the Middle East may depend on shifting emphasis to rainfed farming; in the past, this was not considered possible because of its perceived low productive potential. Recent research, however, has evaluated the status of rainfed farming in Palestine and targeted areas that need improvement. Experiments and demonstrations have shown the potential to vastly improve rainfed farming's production, economic return and status. Following up on these initial steps should be an important priority in maintaining food production in this region.
