The world has entered an era of “global water bankruptcy” that is harming billions of people, a UN report has declared. The overuse and pollution of water must be tackled urgently, the report’s lead author said, because no one knew when the whole system could collapse, with implications for peace and social cohesion. All life depends on water but the report found many societies had long been using water faster than it could be replenished annually in rivers and soils, as well as over-exploiting or destroying long-term stores of water in aquifers and wetlands.

“Water crisis” has become the default label for almost any episode of water stress, from short-lived droughts to decades-long overuse of rivers and aquifers. Yet in many regions of the world, water problems no longer resemble a crisis in the conventional sense. They represent a post-crisis failure state in which human–water systems have exceeded their hydrological carrying capacities, and societies have spent beyond their sustainable hydrological budgets for so long that critical water assets are depleted, some ecosystem damages are irreversible on human time scales, and a return to “normal” is infeasible even with prohibitive economic, social, and environmental costs.

Flagship report calls for fundamental reset of global water agenda as irreversible damage pushes many basins beyond recovery

Satellite analysis warns that widespread land subsidence threatens 1.6 billion people by 2040, with 86% of the at-risk population concentrated in Asia

Like living beyond your financial means, using more water than nature can replenish can have catastrophic results.

Kunstmatige intelligentie heeft een forse ecologische voetafdruk. Onderzoeker Alex de Vries-Gao van de Vrije Universiteit Amsterdam becijferde dat AI-systemen in 2025 tussen 33 en 80 miljoen ton CO2 hebben uitgestoten. Het waterverbruik is nog buitensporiger.

“Combustion is the problem – when you’re continuing to burn something, that’s not solving the problem,” says Prof Mark Jacobson. The Stanford University academic has a compelling pitch: the world can rapidly get 100% of its energy from renewable sources with, as the title of his new book says, “no miracles needed”. Wind, water and solar can provide plentiful and cheap power, he argues, ending the carbon emissions driving the climate crisis, slashing deadly air pollution and ensuring energy security. Carbon capture and storage, biofuels, new nuclear and other technologies are expensive wastes of time, he argues.

De beschikbaarheid van water is in tien jaar tijd met 7 procent gedaald per wereldbewoner. Dat blijkt uit cijfers van de Verenigde Naties.
