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 HISTOIRE POLITIQUE AGRICOLE BILAN HYDRIQUE CULTURE IRRIGUEE PERIMETRE IRRIGUE DELTA REUTILISATION DE L'EAU POLITIQUE DE L'EAU GOUVERNANCE GESTION DE L'EAU SYSTEME D'IRRIGATION EGYPTE 098HYSOC 076AGRO09 Montpellier IRD 2018 9 33 multigr. 33 multigr. 33 multigr. https://www.documentation.ird.fr/hor/fdi:010080195 [F B010080195] https://www.documentation.ird.fr/hor/fdi:010080195 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers21-01/010080195.pdf IRD - Base Horizon / Pleins textes 2020-07-21 2021-02-10 fdi:010080195 fre
