Bienvenue dans le Monde des Eaux Souterraines

Bienvenue dans le Monde des Eaux Souterraines

Les ressources en eaux souterraines à l'échelle mondiale sont d'une importance clé pour le développement durable. Optimiser au maximum les ressources en eaux souterraines tout en contrôlant efficacement leurs problèmes récurrents - comme la surexploitation ou la pollution - sont des tâches très exigeantes. A cet égard, le partage des connaissances et des expériences sur les eaux souterraines à travers le monde serait d'une grande aide. L’IGRAC encourage et soutient cela.

Le travail de l’IGRAC est voué au développement de données et connaissances générales sur les eaux souterraines à l'échelle mondiale et dans un but non-lucratif.
