Abstract: We used a retrospective approach to identify hydrologic metrics with the greatest potential for ecological relevance for use as resource management tools (i.e., hydrologic indicators) in rapidly urbanizing ... read more >>
1) What is the story?
At the Water Summit in Budapest, UN Secretary General Ban Ki-Moon warned that unsustainable water use of water resources could result in one out of every two people on Earth facing water shortages by 2030.
2) Why is it important?
With demand expected to outstrip supply by an estimated 40%, rising conflicts become a threat and sanitati ... read more >>
1. Helicopters are using electrical currents to map soil subsurface in order to locate groundwater, which can provide clean drinking water in India.
2. This story is important because current water supplies in India are over-used and polluted. Being the second most populated country in the world, India is in great need of clean drinking water, and this article provides a potential solution. ... read more >>
Agricultural pollution of surface water, groundwater and marine waters relates to the contamination of drinking water, and harmful effects on ecosystems and costs for recreational activities, cultural values and commercial ﬁsheries. After the introductory section, this paper examines the recent trends and economic costs of agricultural water pollution. Subsequent sections discuss recent Organisat ... read more >>
1. In Tennessee, water is rarely used during fracking operations, due to the geology of southern Appalachia. The company Atlas had better results when fracking with a foam mixture of nitrogen gas, compared with a fracking job pumping 1 514 cubic meters of water down a well. The theory was that the water pumped “gummed up the cracks” in the shale preventing the gas from flowing, whereas the nitrog ... read more >>
Gardeners will claim a victory Tuesday if the Wichita City Council approves an amended drought strategy.
Food-producing gardens that utilize drip irrigation or hand watering would be exempt from watering restrictions until the city reaches drought crisis levels under an amended plan returning to the council.
The new plan by council members Jeff Longwell and James Clendenin is a nod to those who ... read more >>
As close neighbors, China and India share up to 16 major rivers. In recent years, the dispute over water resources has become a contentious issue between the two countries.
There are several main reasons. The first is the conflicts triggered by the development and utilization of cross-border rivers.
The feud over water resource allocation has sparked more claims in India that China poses a thr ... read more >>
Egypt insists Ethiopia's hydroelectric scheme amounts to a violation of its historic rights, a breach of the 1959 colonial-era agreement that allocated almost three-fourths of the Nile waters to Egypt, and an existential threat to a country largely devoid of alternative freshwater sources.
But what Egyptians regard as a nefarious plot by its historic adversary to control its water supply, Eth ... read more >>
Zayandeh-Rud River Basin is one of the most important basins in central Iran, which has been continually challenged by water stress during the past 60 years. Traditionally, a supply-oriented management scheme has been prescribed as a reliable solution to water shortage problems in the basin, resulting in a number of water transfer projects that have more than doubled the natural flow of the river ... read more >>
