    An irrigated area map of the world (1999) derived from remote sensing

    Rapports et recherches
    décembre, 2006
    système d'information géographique

    This document summarizes the materials and methods used to create a series of maps of irrigated areas of the world using remote sensing approaches. These maps are complementary to existing statistics (FAO-Aquastat) and the GISderived maps (FAO/University of Frankfurt Global irrigated area map). The document also provides details of how the estimates of global irrigated areas in one main season (net) and more than one season (intensity or annualized) were derived.

    The Niger River Basin covers 7.5% of the African continent, and is shared between nine riparian

    countries. The basin countries can be categorized into water resources producers, consumers, both

    producers and consumers, and minimum contributors and consumers. As in the case for most

    transboundary rivers, upstream and downstream conflicts emanating from the development and

    utilization of the Niger River are inevitable and are expected to be intense, particularly given the

    This exploratory study was designed to capture the main features of agrarian change in the upper part of the basin that depends mostly on anicuts. These anicuts amount to 59 percent of the total basin anicuts in terms of numbers, but to only 43 percent in terms of irrigated area. They are generally very old (the history of some of them goes back to 2000 years; see below) and obviously, many changes have occurred during this time.
