Résumé :
|
Beyond water's functions in the hydrological cycle, it has social, economic and environmental values, and is essential for sustainable development. Unprecedented population growth, a changing climate,rapid urbanization, expansion of infrastructure, migration, land conversion and pollution translate into changes in the fluxes, pathways and stores of water from rapidly melting glaciers to the decline of groundwater due to overexploitation.Population density and per capita resource use have increased dramatically over the past century, and watersheds, aquifers and the associated ecosystems have undergone significant modifications that affect the vitality, quality and availability of the resource. Current United Nations predictions estimate that the world population will reach 9 billion people in 2050. This exponential growth in population — a major driver of energy consumption and anthropogenic climate change is also the key driver behind hydrologic change and its impacts.
