Survey of hydric resources is elucidated under different conceptions within the national and worldwide environ ment through a bibliographic review. Results show that drought and hydric scarcity, increasing competition on the use of water between different segments of society are a great challenge to governments and population. The seriousness of the situation is still latent. Access to information and implementation of new types of management of hydric resources are required for hydric safety.
