The Middle East Crisis - 2200 BC @ the London Catastrophes conference
Around 2200 BC, something strange happened in the Middle East. An abrupt change in climate caused the sudden collapse of rain-fed agricultural societies in Egypt, the Aegean, the Levant, Mesopotamia and the Indus valley of India. According to Professor Harvey Weiss, people returned to pastoral nomadism or swamped adjacent areas where agriculture... view more... (2002-08-17)
Old McDonald Had a Phytochemical
Forget the moo-moo here and quack-quack there. Farmers may find phytochemicals to be the barnyard bonanza. view more (2007-11-08)
Human activities in arid urban environments can affect rainfall and water cycle
In the past half-century, cities have begun to expand in some of the Earth's most arid areas. While scientists have known for some time that the so-called "heat-island" effect of large cities such as Atlanta and Houston can affect their weather, they knew less about this effect and other processes in arid cities, such as Phoenix, which... view more...

Midwestern ethanol plants use much less water than western plants, U of Minnesota study says
Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows. view more (2009-04-15)
Queen's researchers provide solution to world's worst mass poisoning case
A solution to the world's worst case of ongoing mass poisoning, linked to rising cancer rates in Southern Asia, has been developed by researchers from Queen's University Belfast. view more (2008-08-29)
MIT scientists pinpoint origin of dissolved arsenic in Bangladesh drinking water
Researchers in MIT's Department of Civil and Environmental Engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years. view more (2009-11-16)
A cushion of air trapped under the rice fields of Senegal
Rice cultivation uses great volumes of water, especially where the submerged-field method involving surge flooding irrigation is practised. Maintenance of a layer of water on the soil surface throughout the cropping period usually favours its infiltration deeper down. However, it has been known for many years that in some regions water often does... view more... (2004-04-15)
Rocky water source
Gypsum, a rocky mineral is abundant in desert regions where fresh water is usually in very short supply but oil and gas fields are common view more (2008-06-12)
Strawberry fields ripe for the picking
Many fruit farmers in the United States rely heavily on "pick-your-own" (PYO) operations to realize profits and create repeat business. Pick-your-own fruit farms are an important market segment, and consumer satisfaction with the experience is critical to farmers eager to increase seasonal revenues. view more (2007-12-07)
Wind, Salt, and Water Are Leading Indicators of Land Degradation in Abu Dhabi
Desert environments are characterized by poor vegetative cover, strong winds, dry, non-cohesive sandy soils, and hyper-arid conditions. view more (2009-05-07)
Researchers Turning Freshwater Farm Ponds into Crab Farms
Work by researchers at North Carolina State University is leading to a new kind of crab harvest - blue crabs grown and harvested from freshwater ponds, instead of from the sea. view more (2008-10-10)
Balancing Use to Fill Today`s Gaps and Meet Tomorrow`s Needs: Water for People, Food and Environment Stockholm Water Symposium in August is last major global water forum before UN development summit in South Africa
To feed the planet`s 8 billion inhabitants in 2025, the world will need as much extra water simply for food production as is currently in use for - but not yet satisfying - our drinking, sanitation, industrial and irrigation needs. From where will this new water come? That question will be explored August 12 - 15 by attendees at the 2002... view more... (2002-08-06)
Revising and Re-sizing History: New Work Shows Ohio Site to Be Ancient Water Works, Not a Fort
he site known as Miami Fort is no fort at all, and it is also much larger than previously believed - so large, in fact, that its berms stretch to almost six kilometers in length, making it twice as large as any other Native American earthworks in Ohio, and one of the largest in the nation. view more (2008-09-15)
A new satellite remote sensing tool for improving agricultural land use observation
FAO (Food and Agriculture Organization of the United Nations) data indicate that annually 2500 km3 of freshwater are used for agricultural production, which amounts to 70% of the water resources the whole of humanity consumes in a year. view more (2008-06-04)
Rice U. researchers ask if biofuels will lead to a 'drink or drive' choice
Rice University scientists warned that the United States must be careful that the new emphasis on developing biofuels as an alternative to imported oil takes into account potential damage to the nation's water resources. view more (2009-06-16)
Tunisia: Small Dams Useful For Maintaining Aquifer Levels
In Tunisia, fierce, sometimes catastrophic, flooding is favoured by sudden bursts of rainfall and by erosion- prone soils. This is especially the case in the large wadis in the centre of the country. Large amounts of sediment flow into reservoirs, reducing the useful life of the dams and destroying and depleting the soils in the drainage basins.... view more... (2001-10-11)
Building the lymphatic drainage system
Our bodies' tissues need continuous irrigation and drainage. Blood vessels feeding the tissues bring in the fluids, and drainage occurs via the lymphatic system. While much is known about how blood vessels are built, the same was not true for lymph vessels. view more (2009-04-27)
Satellites unlock secret to northern India's vanishing water
Using NASA satellite data, scientists have found that groundwater levels in northern India have been declining by as much as one foot per year over the past decade. Researchers concluded the loss is almost entirely due to human activity. view more (2009-08-13)
