A recent evaluation of sustainability performance of energy technology systems in rural India reveals that biomass has the highest relative performance followed by hydropower. The sustainability of new and emerging technologies like solar, wind, and their hybrids has improved since 2005.
Integrating traditional practices with modern mechanized agriculture is one way of improving yields and reducing the environmental impact associated with agriculture in developed nations, but policy incentives will likely be required to encourage a meaningful shift in the industry.
Although exhibited in different ways, similar forces drive water management decisions in Israel and in Arizona. Understanding these motivating factors is crucial when developing successful and effective water management approaches.
Regional differences in the impacts of the urban heat island effect across the US are largely explained by variations in efficiency of heat convection to lower atmosphere and strongly influenced by humidity patterns rather than evapotranspiration.
Recent climate projections for India, based on the regional climate models, identify that India would face more days of extreme rains and more consecutive dry days – which would lead to more floods and more droughts, towards the end of the 21st century.
Multiplied by hundreds of wells, total shale gas use in the Wattenberg Shale in northeastern Colorado is in the vicinity of a billion gallons or more — and in a basin that is actively seeking new water sources to meet existing demand.
A new model suggests it may be possible to feed the world's growing population with minimal environmental impact, but doing so will require targeted policies to reduce food waste and incentives towards healthier diets in industrialized nations.
Ecosystem services are the tangible benefits natural systems provide to humans. Increasingly, the ecosystem services concept has been recognized for its value in the decision-making process. This is true at geographic scales ranging from small villages to entire continents. Defining the ecosystem services provided by a region necessarily involves both human values and the collection of scientific data.
A national carbon policy may exasperate water shortages in the western United States. Yet, the high cost of water reduction in the electricity sector makes it an unlikely candidate for mitigating water consumption in light of climate change and carbon policies.
