In Brazil, 68% of municipalities collect freshwater for public supply from deep wells, with water levels seen to be receding. Current knowledge about Brazilian waters is based mainly on surface waters — rivers, flood plains, lakes and reservoirs. A new model developed by the Geological Survey of Brazil promises to... read more...

Europe has long been proud of its clean water: accessible, abundant, and drinkable. Most of what we drink, irrigate our crops with, and use in our industries, comes from deep underground, from within vast labyrinths of aquifers. This precious groundwater sustains an entire continent and has helped turn Europe into... read more...

A recent study highlights the perilous situation of oases around the world. Once seen as places of imagination, today they support important habitats and water sources for arid regions, which deserve sustainable development. Despite covering only a small fraction, about 1.5%, of our planet’s land area, oases play a disproportionately... read more...
