Water’s usability doesn’t need to end once it's flushed down the drain. Rather, India can see industrial and domestic wastewater as a valuable resource from which water, nutrients and even renewable energy can be extracted.
Water security drives state stability and safety in many regions of the world. The direct and indirect effects of water stress—such as migration, food shortages and general destabilization—transcend national boundaries.
A changing climate means less rain and lower water supplies in regions where many people live and much of the planet's food is produced, as clouds retreat toward the North and South poles. A new study shows this cloud shift is already taking place, with huge implications for agriculture, industry and municipal water provisioning.
Research on future water risk finds that rapidly growing demand for water will drive the greatest increase in water stress, even more so than supply changes caused by droughts and other extreme events.
More than 100 companies have now committed to use the best science available as the basis for setting greenhouse gas emissions-reduction targets. Targets informed by science might well be effective in reducing risks posed by water as well—but there are hurdles to overcome first.
Four Chinese cities are pursuing systems that turn "sludge," the organic matter left over from treated sewage, into energy. The systems can reduce emissions, energy consumption and water pollution all while saving money.
While droughts, floods and increasingly rapid groundwater depletion are cause for concern, this year presents unprecedented opportunities to pursue better water management. Director of WRI's Global Water program Betsy Otto explains.
Electricity for water treatment can be as much as one-third of a city's energy bill, and these "energy-water nexus" issues are becoming more and more concerning for businesses. A new GE and WRI report explores three innovative solutions for energy and water management.
