While progress has been made on quantifying virtual water ﬂows between countries, there exists little information on virtual water trade within large countries like India. This paper presents the results of two MSc theses which quantify and critically analyze inter-state virtual water ﬂows in India in the context of a large inter-basin transfer plan of the Government of India. ... read more >>
The record loss of Arctic sea ice this summer will echo throughout the weather patterns affecting the U.S. and Europe this winter, climate scientists said on Wednesday, since added heat in the Arctic influences the jet stream and may make extreme weather and climate events more likely. ... read more >>
For the most part, many people still experience climate change on an academic rather than a personal level. But for the villagers of Vunidogoloa on Vanua Levu, Fiji’s second largest island, climate change has become a daily intrusion on every day life.

When it rains, storm water washes into the same system of underground pipes that carries the region's sewage, and 1 bil ... read more >>
Another small insight into how climate change may influence extreme weather: Scientists from Tel Aviv University say that their new research shows that for every 1°C of warming there will be roughly a 10% increase in lightning activity. ... read more >>
It seems world leaders may need to retake environmental studies. As the Rio+20 Summit on Sustainable Development opens, the scientific journal, Nature, has evaluated the progress made on three treaties signed at the Rio Earth Summit in 1992: climate change, biodiversity decline, and desertification. Unfortunately the publication gives progress on all three treaties an 'F', highlighting how little ... read more >>

A fleet of 100 floating robots took a trip down the Sacramento River, USA in a field test organized by engineers at the University of California, Berkeley. The smartphone-equipped floating robots demonstrated the next generation of water monitoring technology, promising to transform the way government agencies monitor one of the state's most precious resources.
The Floating Sensor Network proj ... read more >>
