Dans le cadre du Millennium Challenge Account (MCA), don de 540 millions de dollars r\u00e9partis entre 2010 et 2015 et destin\u00e9 \u00e0 acc\u00e9l\u00e9rer la croissance en vue de r\u00e9duire la pauvret\u00e9, il \u00e9tait projet\u00e9 une valorisation des ressources en eau dans le Delta et la vall\u00e9e du Fleuve S\u00e9n\u00e9gal. Principalement compos\u00e9 de deux volets, la r\u00e9alisation du sch\u00e9ma hydraulique du Delta et l\u2019am\u00e9nagement de cuvettes d\u2019inondations dans le Podor, le projet consistait en la mise en place d\u2019infrastructures hydro-agricoles dans le but notamment de favoriser le d\u00e9veloppement dans cette r\u00e9gion et d\u2019assurer une disponibilit\u00e9 permanente de l\u2019eau pour permettre des cultures durant toute l\u2019ann\u00e9e et ainsi ambitionner l\u2019autosuffisance en riz, en tomate, en oignon et en pommes de terre d\u2019ici 2017. En compl\u00e9ment des 165 Km de cours d\u2019eau naturels qui ont fait l\u2019objet de curage, de faucardage et d\u2019endiguement pour assurer une disponibilit\u00e9 permanente de l\u2019eau et am\u00e9liorer ainsi l\u2019hydraulicit\u00e9, ce sont aussi 4 grands ouvrages qui ont \u00e9t\u00e9 r\u00e9alis\u00e9s pour servir d\u2019\u00e9missaire de drainage et garantir ainsi la durabilit\u00e9 des am\u00e9nagements et les conditions environnementales d\u2019exploitation des p\u00e9rim\u00e8tres irrigu\u00e9s.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
