C’est un syst\u00e8me d’irrigation potentiellement r\u00e9volutionnaire. Son nom : \u00ab\u00a0le diffuseur enterr\u00e9<\/em>\u00ab\u00a0. Il permet d’arroser les cultures directement \u00e0 la racine, alors qu\u2019avec l\u2019arrosage classique \u2013 en surface \u2013 la majorit\u00e9 de l\u2019eau s\u2019\u00e9vapore avant m\u00eame de nourrir la plante. Objectif\u00a0: \u00e9conomiser une eau de plus en plus rare, particuli\u00e8rement en Afrique du Nord.<\/p>\n\n\n\n

Son inventeur ? Un Tunisien \u2014 Bellachheb Chahbani \u2014 agronome, sp\u00e9cialiste des zones arides. Il a mis 20 ans \u00e0 \u00e9laborer ce syst\u00e8me. Le \u00ab\u00a0diffuseur enterr\u00e9<\/em>\u00a0\u00bb a d\u00e9j\u00e0 re\u00e7u de nombreux prix mais peine \u00e0 s’imposer sur le march\u00e9. Il pourrait vivre bient\u00f4t un tournant. Son fils – Wassim – 28 ans a r\u00e9ussi \u00e0 convaincre le jury du Prix de l’Innovation pour l’Afrique 2018. Le diffuseur fait partie des 10 finalistes distingu\u00e9s parmi 3000 projets issus de 52 pays. La finale aura lieu dans quelques semaines. A la cl\u00e9 ? 185.000 dollars, et une vitrine unique.<\/p>\n\n\n\n

Nourrir la plante d’eau et d’engrais \u00e0 la racine<\/h2>\n\n\n\n

Le diffuseur enterr\u00e9 permet \u00e0 l’agriculteur de r\u00e9duire les doses d\u2019engrais gr\u00e2ce \u00e0 une diffusion plus cibl\u00e9e. Mais surtout – changement climatique oblige – il permet de diminuer la quantit\u00e9 d\u2019eau utilis\u00e9e. \u00ab\u00a0On enterre le diffuseur \u00e0 50 centim\u00e8tres de profondeur pour l’arboriculture. Le diffuseur utilise 70% moins d’eau que le syst\u00e8me d\u2019irrigation au goutte \u00e0 goutte<\/em>\u00ab\u00a0, explique Bellachheb Chahbani. Or, aujourd’hui, dans toute la r\u00e9gion, c’est le goutte \u00e0 goutte qui pr\u00e9domine.<\/p>\n\n\n\n
