How Rainwater Could Save Rupees
June 29, 2015 11:24 AM - Ashley Morrow, NASA Goddard Space Flight Center

Rainwater could save people in India a bucket of money, according to a new study by scientists looking at NASA satellite data. The study, partially funded by NASA’s Precipitation Measurement Missions, found that collecting rainwater for vegetable irrigation could reduce water bills, increase caloric intake and even provide a second source of income for people in India.

What California can learn for Israel on solving serious water shortages
June 29, 2015 06:13 AM - Jan Lee, Triple Pundit

California is still counting up the damage from the 2014 drought, which resulted in more than $200 million in losses in the dairy and livestock industry and a staggering $810 million in crop production. And analysts are predicting this year to be even worse.

But many will admit that if there is any country on earth that knows how to trump a three-year (and counting) drought cycle and convert a wasteland to oasis, it’s Israel. For thousands of years, populations have been wresting a livelihood from the desert of what is now Israel, refining the techniques that would one day result in an agricultural paradise.

Study examines overall carbon cost of fuel from Canadian oil sands

Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over the oil’s lifetime than fuel from conventional crude sources in the Unied States, according to a study by the U.S. Department of Energy’s Argonne National Laboratory; the University of California, Davis; and Stanford University.

The researchers used a life-cycle, or “well-to-wheels,” approach, gathering publicly available data on 27 large Canadian oil sands production facilities. The study, published in the journal Environmental Science and Technology, found the additional carbon impact of Canadian oil sands was largely related to the energy required for extraction and refining.

Beijing growing explosively, impacting weather and climate
June 26, 2015 05:12 AM - JPL NASA

A new study by scientists using data from NASA's QuikScat satellite has demonstrated a novel technique to quantify urban growth based on observed changes in physical infrastructure. The researchers used the technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009. 

A team led by Mark Jacobson of Stanford University, Palo Alto, California, and Son Nghiem of NASA's Jet Propulsion Laboratory, Pasadena, California, used data from QuikScat to measure the extent of infrastructure changes, such as new buildings and roads, in China's capital. They then quantified how urban growth has changed Beijing's wind patterns and pollution, using a computer model of climate and air quality developed by Jacobson. 

Nepal deals with climate change

On 25 April, Nepal was hit by a 7.8 magnitude earthquake. But as well as quakes, the country is also vulnerable to climate change, a combination that makes it harder to build resilience and risk preparedness.
 
As mean temperatures rise in South Asia, the monsoon season has changed, leading to more-erratic rainfall and increasing the risk of floods and landslides that can claim lives and wreck food production.
 

Why do Americans waste so much food?
June 23, 2015 04:11 PM - Judy Molland, Care2

Americans throw away nearly half of their food every year, waste worth roughly $165 billion annually, according to a study by the Natural Resources Defense Council (NRDC). The report estimates that the average American family of four ends up throwing away an equivalent of up to $2,275 annually in food. Even worse, there is evidence that there has been a 50 percent jump in U.S. food waste since the 1970s.

Seven Billion Dreams. One Planet. Consume with Care. That is the theme of this year's World Environment Day – celebrated today, June 5th! Established by the United Nations General Assembly in 1972, World Environmental Day (WED) helps raise awareness to protect nature and encourage worldwide awareness and action for environmental protection.

Switzerland Promotes Neighborhood Exchange Boxes
June 1, 2015 08:49 AM - Tex Dworkin, Care2

If someone were to set up a telephone booth sized box on your street filled with unwanted items — such as books, toys and small knick knacks, perhaps — and then topped it off with a “Free” sign, what do you think would happen? If Switzerland is any indication, passersby turned salvagers and recyclers would appear out of nowhere, sifting their way through other people’s unwanted discards, thinking up ways to put their newfound discoveries to good (re)use. Some would even add their own unwanted items to the box. Neighborhood exchange boxes have helped Geneva, Switzerland reuse 32 tons of goods thus far thanks to a program called BOÎTES D’ÉCHANGE ENTRE VOISINS–A box for exchange between neighbors. But can it work in other cities?

Celebrate Today - International Day for Biological Diversity!
May 22, 2015 09:08 AM - Editor, Population Matters

International Day for Biological Diversity 2015 is 22 May. The theme for the Day this year is “Biodiversity for Sustainable Development”. More than 4,500 mammal, bird and amphibian species are currently deemed at risk of extinction. Not all species have been catalogued, so we do not know exactly how many we are losing each year, but a report recently published in the journal Natuesuggests that approximately 41 per cent of amphibian species, 26 per cent of mammal species and 13 per cent of bird species are likely to be lost in the near future.
