The recently released National Climate Assessment discussed the impacts of climate change on our nation’s water supply and agricultural productivity. The levels of uncertainty regarding the future of our water supply are troubling. Changes in precipitation patterns will intensify droughts and increase heavy downpours. Hotter, more extreme weather will disrupt how well and how … [more…]

Fecal contamination of urban and peri-urban water bodies is a major health issue in most low- and middle-income countries, where population growth exceeds the rate of development of wastewater or fecal sludge collection and treatment infrastructure. While the expansion of sewer systems and treatment capacity remain a high priority for municipal authorities, there are opportunities for applying low-cost, small-scale on-farm options for safe recovery of wastewater and fecal sludge for … [more…]
