UN: Water Management Can Lessen Impact of Climate Change Lisa Schlein GENEVA - Water management can blunt the impact of climate change and reduce greenhouse gas emissions that lead to global warming, reports UN-Water, an agency that works on water and sanitation issues. About 90 percent of all major natural disasters are water-related, according to the United Nations. Floods, storms, heat waves, droughts and other water-related events are responsible for tens of thousands of deaths, as well aseconomic losses that run into hundreds of billions of dollars. UN-Water spokeswoman Daniella Bostrom Couffe says while water management can be used to mitigate the effects of climate change, the measures are largely overlooked. .
