Abstract:Traditionally, crops have been watered from the Nile either by the natural flooding of banks and past courses of the river, by the saqiya (water wheel) or by the more primitive counterpoised: shaduf (bucket). Only a modest land area can be commanded by the last two devices while considerable expenditure of either animal- or man-power is necessary. The introduction of mechanical pumps has faciltated both an increase in irrigated area and a move toward a more highly commercialised riverain agriculture. Pump irrigation is of considerable economic significance both as a source of livelihood and employment in the agricultural sector and as a source of foreign exchange earnings and government revenues. It has provided an opportunity for the economy's private sector to invest in the expansion of irrigation agriculture. In the past few years, however poor economic performance especially in the case of cotton schemes, has reduced the rate at which new schemes are being established. The author reviews the development to date and analyses the economic performance of the existing agriculture to suggest lines for futther development. References, tables.
