Les eaux souterraines sont un bien commun mondial, indispensable \u00e0 la vie et au d\u00e9veloppement. Leur pr\u00e9servation est un d\u00e9fi collectif qui conditionne l\u2019avenir de millions de personnes et la sant\u00e9 des \u00e9cosyst\u00e8mes.<\/em><\/strong><\/p>\n

C\u2019est dans ce cadre que l\u2019ing\u00e9nieur et expert en ressources en eau Mohamed Salah Gla\u00efed a soulign\u00e9, dans un post publi\u00e9 sur sa page Facebook,\u00a0 l\u2019importance capitale des eaux souterraines pour l\u2019humanit\u00e9 et leur r\u00f4le strat\u00e9gique dans la s\u00e9curit\u00e9 hydrique mondiale.
\nSelon lui, les eaux souterraines repr\u00e9sentent pr\u00e8s de 99 % de toutes les r\u00e9serves mondiales d\u2019eau douce liquide et constituent actuellement un quart de toute l\u2019eau douce utilis\u00e9e par l\u2019homme. Bien que pr\u00e9sentes en abondance sous la surface, leur disponibilit\u00e9 varie fortement d\u2019une r\u00e9gion \u00e0 l\u2019autre, certaines zones \u00e9tant particuli\u00e8rement d\u00e9pendantes de cette ressource pour l\u2019alimentation en eau potable et l\u2019irrigation.<\/p>\n

Mohamed Salah Gla\u00efed<\/p><\/div>\n

Gla\u00efed a rappel\u00e9 que les eaux souterraines fournissent environ la moiti\u00e9 de l\u2019eau domestique consomm\u00e9e dans le monde, y compris pour la majorit\u00e9 des populations rurales non desservies par des r\u00e9seaux publics ou priv\u00e9s. Elles repr\u00e9sentent \u00e9galement pr\u00e8s de 25 % de l\u2019eau utilis\u00e9e pour l\u2019irrigation, ce qui en fait un pilier essentiel pour l\u2019agriculture et la s\u00e9curit\u00e9 alimentaire. Dans certaines r\u00e9gions \u00e0 forte activit\u00e9 agricole, cette part peut atteindre jusqu\u2019\u00e0 40 % de l\u2019eau utilis\u00e9e pour les cultures, soulignant la d\u00e9pendance des syst\u00e8mes agricoles aux nappes phr\u00e9atiques.
\nL\u2019expert a \u00e9galement alert\u00e9 sur la croissance continue de la demande en eau, estim\u00e9e \u00e0 1 % par an au niveau mondial au cours des trois prochaines d\u00e9cennies. Cette augmentation est aliment\u00e9e par la croissance d\u00e9mographique, l\u2019\u00e9volution des modes de consommation et le d\u00e9veloppement \u00e9conomique, mettant davantage de pression sur les ressources existantes et accentuant les risques de surexploitation.
\nEnfin, Mohamed Salah Gla\u00efed a insist\u00e9 sur la n\u00e9cessit\u00e9 d\u2019une gestion durable et proactive des eaux souterraines, combinant protection des aquif\u00e8res, r\u00e9duction des pertes, am\u00e9lioration des r\u00e9seaux de distribution et sensibilisation des usagers. Il a rappel\u00e9 que ces ressources repr\u00e9sentent non seulement un outil essentiel pour l\u2019acc\u00e8s \u00e0 l\u2019eau potable, mais aussi un levier strat\u00e9gique pour l\u2019agriculture, le d\u00e9veloppement \u00e9conomique et l\u2019adaptation au changement climatique.<\/p>\n","protected":false},"excerpt":{"rendered":"
