| 摘 要： | The G-WADI network by UNESCO promotes the global capacity for management of water resources in arid and semi-arid areas.The primary aim has been to build a comprehensive global network to promote regional and international cooperation so as to increaseknowledge and improve management practices through the sharing of information. The G-WADI objectives and achievementsof the past 10 years are reviewed. A number of key initiatives have been implemented––the formation of five regional networks,the creation of a central G-WADI web site, promotion of near-real-time rainfall distribution software enhanced by the inclusionof satellite based precipitation estimations, as well as workshop and web-based activities on chemical and isotopic tracersand on rain water harvesting. Two workshops on surface and on groundwater modeling, supported by publications have been heldin India and China. The Asian G-WADI network remains very active, but activities in the other three regions are developing (Africa,Arab Region, Latin America and the Caribbean).
