Water scarcity is a pressing global challenge which must be addressed promptly with sustainable solutions. This essay discusses fog harvesting as a promising supplemental water source in the coastal regions of South America. Fog harvesting proves to be a highly cost-effective and energy-efficient ...
Water scarcity occurs when there are insufficient freshwater resources to meet the human and environmental demands of a certain area. Given the challenges of population growth, profligate use, growing pollution, and global warming, many countries and maj
As a result ofclimate change, the report said, “seasonal water scarcity will increase in regions where it is currently abundant — such as Central Africa, East Asia and parts of South America — and worsen in regions where water is already in short supply, such as the Middle East and the...
climate change, the report said, “seasonal water scarcity will increase in regions where it is currently abundant — such as Central Africa, East Asia and parts of South America — and worsen in regions where water is already in short supply, such as the Middle East and the Sahara in ...
The role of increasing water scarcity is important because expanding existing systems is much more expensive per unit of water than the average cost used in these comparisons. This means that presented cost analyses probably underestimate the economic value of decentralized systems because the increasing...
Water scarcity as a result of climate change will create far-reaching global security concerns, says Dr. Rajendra K. Pachauri, chair of the intergovernmental panel on climate change, a co-recipient of the 2007 Nobel Peace Prize.
Nevada Faces Water Scarcity More George Rose|Getty Images Nevada has reached a "critical mass" of its water supply, according to an official, leaving the state to consider how it will supply enough water for its growing population. "Between historical over-appropriation and over-p...

To understand how freshwater scarcity constrains production of these goods, we need to consider limits to the green water footprint (WF g ), the green water flow allocated to human society. However, research traditionally focuses on scarcity of blue water––groundwater and surface water. Here ...
Water scarcity is rapidly increasing in many regions. In a novel, multi-model assessment, we examine how human interventions (HI: land use and land cover change, man-made reservoirs and human water use) affected monthly river water availability and water
