Molle François auteur aut IRD text bookSection eng text/pdf born digital access In no other country, perhaps, is the identification between water, irrigation, and agriculture as strong as in Egypt. Several phases of agrarian and technical change throughout its long history have taken Egypt to a situation where farmers grow between one to three crops a year on 3.78 million ha after lifting water from canals and drains, and sometimes from aquifers. This chapter first reviews the extraordinary cost of maintaining the delta 'irrigation machine', the history of irrigated agriculture expansion, and the evolution of public policies. It then examines key issues and challenges, including irrigation modernization, the search for water savings, the multiple experiences with participatory management at various scales, inter-sectoral integration, the water-food-energy nexus, the recent masterplan, and finally transboundary threats. specialized IRRIGATION AMENAGEMENT HYDROAGRICOLE COUT MODERNISATION TECHNOLOGIE BILAN HYDRIQUE CULTURE IRRIGUEE EXPANSION HISTOIRE PENURIE RESSOURCES EN EAU BESOIN EN EAU DELTA VALLEE REUTILISATION DE L'EAU GESTION DE L'EAU POLITIQUE DE L'EAU GOUVERNANCE EGYPTE 062EVAEAU03 098HYSOC Molle François ed. edt IRD Sanchis-Ibor C. ed. edt IRD Avellà-Reus L. ed. edt IRD 22 243-277 Cham Springer 2019 22 https://www.documentation.ird.fr/hor/fdi:010080177 978-3-03-003696-6 [F A010080173] https://www.documentation.ird.fr/hor/fdi:010080177 https://www.documentation.ird.fr/intranet/publi/depot/2021-03-11/010080177.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2020-09-28 2021-03-24 fdi:010080177 fre
