Thousands still lack access to quality food and grocery stores CHICAGO, June 18 /PRNewswire/ -- In 2006, the groundbreaking report Examining the Impact of Food Deserts on Public Health in Chicago identified more than 630,000 Chicagoans living in "food deserts," communities where fresh, quality food is hard to come by because of the lack of reputable grocery stores. A wide range of market, community and government actors used the report to take action. Now, according to The Chicago Food...

Reconstructing the climate of the past is an important tool for scientists to better understand and predict future climate changes that are the result of the present-day global warming. Although there is still little known about the Earth's tropical and subtropical regions, these regions are thought to play an important role in both the evolution of prehistoric man and global climate changes. New North African climate reconstructions reveal three "Ëœgreen Sahara' episodes during...

China finds 14,000-km underground rivers in rock desert areas BEIJING, Sept. 29 (Xinhua) -- A newly conducted geological survey has found more than 3,000 underground rivers with a total length of 14,000 kilometers in southwest China's rock desert areas. A latest report released by the China Geological Survey showed that these underground rivers collect water from a combined area of 300,000 square kilometers, with an annual runoff of 47 billion cubic meters, equivalent to that of the Yellow...

Water from rock, easier than blood from stoneGypsum, a rocky mineral is abundant in desert regions where fresh water is usually in very short supply but oil and gas fields are common. Writing in International Journal of Global Environmental Issues, Peter van der Gaag of the Holland Innovation Team, in Rotterdam, The Netherlands, has hit on the idea of using the untapped energy from oil and gas flare-off to release the water locked in gypsum.Fresh water resources are scarce and will be more so...

A recent study on the future of climate changes suggests that the once-green Sahara turned to desert over thousands of years rather than in an abrupt shift as previously believed. The study's lead author said that parts of the Sahara now show signs of a tiny shift back towards greener conditions, apparently due to global warming.The researchers looked at ancient pollen, spores and aquatic organisms in sediments in Lake Yoa in northern Chad that show that the region gradually shifted from...

MOFFETT FIELD, Calif. -- Searching for clues to the potential for life on Mars, NASA scientists recently explored microbial communities in some of the world's oldest, driest and most remote deserts, in China's northwest region, and found evidence suggesting that conditions there may be similar to those in certain regions of Mars. This is the first comprehensive study of microbial ecosystems in the extreme deserts of China. Scientists looked for microbial life and tried to determine climate's...

By Michael Byrnes DICKS CREEK, Australia (Reuters) - Farmer John Ive squints through the barbed wire fence separating the roadside from an ulcerous patch of ground where salt has risen from the earth to collapse the land into crumbling, barren ravines. Black stumps from an earlier fence, decayed from the bottom up by salt, dance from wire strands in the biting wind. "These sites are pockmarked across the southern tablelands," says Ive, shaking his head in despair at desertification...

By Hamid Ould Ahmed ALGIERS (Reuters) - The United Nations used World Environment Day on Monday to warn that the growth of deserts was a growing obstacle to ending poverty and a threat to peace. To mark the day under the slogan "Don't desert drylands!," environmentalists were planting trees to slow erosion, cleaning cities, going on marches and holding special lessons in school. Algerian President Abdelaziz Bouteflika, whose largely desert country was officially hosting the campaign, urged...

By Jeremy Lovell LONDON (Reuters) - Far from being barren wastelands, the deserts that occupy one quarter of the earth's land surface could be key sources of food and power, the United Nations said on Monday. But these vast open spaces, home to rare and useful plants and animals, are at risk from climate change and human exploitation, the UN's Environment Program said in a report published on World Environment Day. Deserts are prime potential locations for solar power generators that do not...

Desert greening is made up of any number of methods used to revitalize deserts. So far, only arid and semi-arid desert are meant when using this expression. The icy deserts and other types are considered to be unsuitable. The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...

The sand Cat (Felis margarita) is a small wild cat 19.69 inches (50 cm) long, plus an 11.81 in (30 cm) tail. It is distributed over African and Asian deserts. The name "Desert Cat" is reserved for a subspecies of the true Wild Cat, but it would go better with this species. It lives in those dry areas that are even too hot and dry for the Desert Cat. These areas are the Sahara, the Arabian Desert, and the deserts of Iran and Pakistan. The head is conspicuously broad and the ears are large...
