Guidelines for eco-industrial parks based on food webs: Three researchers at Texas A&M University drew inspiration from food webs found in nature to develop guidelines for designing more resilient eco-industrial parks. The results suggest that the approach will assist in addressing environmental, economic and resiliency concerns.
Glacial meltwaters in Greenland contain mercury: An international team of researchers have discovered higher than expected levels of mercury in glacier meltwater rivers in Greenland. The source of the mercury is thought to be geological.
Map of groundwater recharge rates published for Africa: Many communities in Africa rely on groundwater for domestic and agricultural use. Unsustainable abstraction rates can deplete sources of groundwater with disastrous consequences. The map, based on ground-based studies, provides an estimate of the long-term distributed groundwater recharge for the period 1970 to 2019. The results contribute to the understanding of water security in African countries.
