Usually we think of demolished concrete walls and floors as environmental contaminants, but in fact this material may turn out to be a valuable resource in nature protection work. This is the conclusion from researchers from University of Southern Denmark after studying the ability of crushed concrete to bind phosphorus.
This is the second in a two-part series on the water-energy nexus and this post focuses on the City of San Diego. The previous post, discussed the energy and greenhouse gases associated with moving water in the state of California. Generally, the water-energy nexus refers to how energy is consumed and embedded within the water use cycle. A common

Today is World Environment Day, a date established in 1970 to raise awareness of pressing ecological issues. Every year, the United Nations Environmental Protection agency chooses a theme to promote on this date; in 2013 the theme is food waste. One third of the food produced globally is wasted and, with it, we waste a great deal of energy and water as well, since
A conference of 500 of the world’s leading water scientists issued a stark declaration at the end of a four-day meeting in Germany, warning that within two generations a majority of the people on the planet will face problems obtaining ample supplies of clean water.

Gardening is not only one of the healthiest hobbies you can have – both in terms of physical productivity and the “fruits” of your labour – but also one of the most sustainable. Still, depending on your practices (as well as your location), it can seem to be an ironically large waste of water, particularly here in Australia.
China’s Guangdong Province water company is currently in the process of installing 75 water analyzing and control units supplied by global water quality control systems provider Blue I Water Technologies, BlueI informed Israel NewTech. The units will accurately measure a range of parameters for municipal potable water, to ensure drinking water
China’s five largest power utilities, which depend on water-intensive, coal-fired stations to generate electricity, are vulnerable to water supply disruptions because they are centered in the country’s water-scarce northern regions, a new report says.
According to Bloomberg New Energy Finance, the five power generators — Huaneng, Datang, Huadian, Guodian, and China Power Investment — operate
Expansion of City in Western China Poses Environmental, Safety Risks, Critics Say
written by Yale Environment 360
An ambitious plan to expand the western Chinese city of Lanzhou into a regional industrial hub is raising concerns over what critics call lax government oversight of the environmental and safety impacts, including worries that it will siphon huge amounts of water from an already parched region and devastate nearby mountains.
All across the globe, communities are celebrating International World Water Day and according the UN’s World Water Day website, over 450 events have been planned this year!
This year’s theme is in part a reflection of the International Year of Water Cooperation. The day is
Lockheed Martin, one of the world’s largest military contractors, has developed a process that company officials say significantly reduces the amount of energy needed to desalinate water, an innovation that could help communities worldwide tackle the growing threat of water scarcity.
