Fresh Thinking: Freshwater Science Is Being Pioneered in Arizona

About 71 percent of the Earth is covered by water, and most of that is ocean. Only 2.5 percent is fresh water, and only a fraction of that—1 percent—is easily accessible. The world’s population of 7.6 billion is expected to grow to 9.8 billion by the year 2050, which means by that year, more than half the people on Earth will live in water-stressed areas. The demand for potable and … [more…]

When delegates to the second International Irrigation Congress convened in Los Angeles in October 1893, pessimism about their mission was not supposed to be on the agenda. The gathering, after all, was meant to encourage reclamation of arid lands throughout the American West, using irrigation to transform an immense wasteland into an agriculturally … [more…]
