A new tax aimed at property owners could finance the first set of improvements of the drainage works in Salisbury, Maryland since the original system was laid almost a century ago. City leaders have been arguing since 2009 over dedicating a source of funding to stormwater management, when an environmental panel recommended it. In the past, funding for projects like this has been hard to find as other priorities were deemed more important.

As world food and energy demands grow, nations and some corporations increasingly are looking to acquire quality agricultural land for food production. Some nations are gaining land by buying up property — and accompanying water resources — in other, generally less wealthy countries.

Some forty million people depend on the Colorado River Basin for water, but warmer weather from rising greenhouse gas levels, and a growing population, may signal water shortages ahead; scientists predict a 10 percent drop in the Colorado River’s flow in the next few decades, enough to disrupt longtime water-sharing agreements between farms and cities across the American Southwest, from Denver to Los Angeles to Tucson, and through California’s Imperial Valley

Recent changes in the Environmental Protection Agency’s (EPA) surface water treatment rules mandate, among other things, more aggressive monitoring and control of various pathogens, notably including Cryptosporidium; this microbe, which can cause severe illness or death, is highly resistant to chlorine-based disinfection practices; as one means to reducing the threat, the EPA has called for treating water with ultraviolet (UV) radiation, which also serves as a “secondary barrier” to inactivate (prevent reproduction of) other key pathogens such as adenovirus and other viruses, as well as bacteria and parasites such as Giardia

The U.S. National Intelligence Council, the research arm of the Office of the Director of National Intelligence, yesterday released its Global Trends 2030; the report’s authors say that food, water, and energy will be more scarce; “Nearly half of the world’s population will live in areas experiencing severe water stress,” the report notes; Africa and the Middle East will be most at risk of food and water shortages, with China and India also vulnerable; one bright spot for the United States: energy independence sometime between 2020 and 2030

Four of the world’s great rivers are all suffering from drastically reduced flows as a direct result of water extraction, according to new research; the researchers found that in all four river basins, over a long period of time, outflows have greatly reduced as a direct result of increased water extractions, and that urgent changes in governance of water are needed to ensure the systems remain healthy and viable

Snowpack, an essential source of drinking water and agricultural irrigation for billions of people, could shrink significantly within the next thirty years; the news is particularly troubling for snowpack-dependent California — the largest producer of agriculture products in the country and the sixth-largest agriculture exporter in the world; by filling reservoirs and watering crops when warmer, drier weather sets in, mountain snowpack has become vital to people and ecosystems in regions such as the Western United States, Alpine Europe, Central Asia, and downstream of the Himalayas and Tibetan Plateau — home to more than 50 percent of the world’s population

Just-released paper offers policy makers innovative framework for linking human well-being and water quality; a new tool helps in assessing and valuing the many services clean water provides — from recreation and beauty to navigation and hydropower — and incorporating them into policy decisions

Excessive nutrients in U.S. rivers, streams, and coastal areas are a major issue for water managers, because they cause algal blooms that increase costs to treat drinking water, limit recreational activities, and threaten valuable commercial and recreational fisheries; U.S. Geological Survey crews are sampling water for nutrients, sediment, and pesticides to document water quality in areas affected by the hurricane
