    This article is based on the FAO study “Irrigation potential of Africa: a basin approach” and it is part of the proceedings of the international workshop on “Remote sensing and water resources” (http://www.fao.org/docrep/W7320B/w7320b00.htm) organized by FAO, in collaboration with the Comité interafricain d'études hydrauliques (CIEH), the Laboratoire commun de télédétection Cemagref-Engref (LCT) and Orstom (Institut français de recherche en coopération) and published in 1997. The study FAO undertook in 1995 investigated the potential use of remote sensing and geographic information systems in water resources assessment of small watersheds in semi-arid areas of West Africa. The use of the Arc-Info geographic information system allowed to define the geographical computation units, which are homogeneous regarding average rainfall, potential evapotranspiration, cropping pattern (calendar, intensity) and irrigation efficiency. Combining information on gross irrigation water requirements, area of soils suitable for irrigation and available water resources by basin eventually resulted in an estimation of the physical irrigation potential for Africa.

    Irrigation in the Middle East region in figuresAquastat Survey – 2008 2009
    Also available in:

    The AQUASTAT Programme was initiated with a view to presenting a comprehensive picture of water resources and irrigation in the countries of Africa, Asia, Latin America and the Caribbean and providing systematic, up-to-date and reliable information on water for agriculture and rural development. This report presents the results of the most recent survey carried out in the 18 countries of the Middle East region, and it analyses the changes that have occurred in the ten years since t he first survey. Following the AQUASTAT methodology, the survey relied as much as possible on country-based statistics and information. The report consists of three sections. Section I describes in detail the methodology used. Section II contains the regional analysis which presents a synopsis on water resources development and irrigation in the region, including a more detailed description of four transboundary river basins: the Euphrates-Tigris, Kura-Araks, Asi-Orontes and Jord an river basins. Section III contains the detailed profiles on the situation in each country.
