Shallow canals and low water levels in Argentina have grounded two bulk carriers, causing significant delays in the country’s major grains terminal, MercoPress reported. Concerns about water levels have prompted Argentina and Uruguay to agree to dredge the Martin Garcia canal deeper as the inevitable expansion of the Panama Canal will give rise to a […]
The falling price of photovoltaic panels and public concerns about aquifers and rivers in the western United States are boosting solar energy technologies that save water. In December, the U.S. Department of the Interior (DOI) approved a 300-megawatt (MW) solar energy project on public land in southwestern Arizona on condition that the developer changes the […]
Australia’s first law intended to protect prime agricultural land from mining has come into effect in Queensland, ABC reported. Though the law covers about 4 percent of the state’s land, critics say it will only apply to open-pit mining and not cover underground mining, exploration work or coal seam gas (coal-bed methane) production. Australia is […]
Urban waste and falling water levels signaled a rough start to 2012 for some of the world’s largest and most iconic freshwater lakes. Image courtesy NASA Dry weather and pollution are plaguing some of the major lakes in China, Africa, South and North America at the start of the year, posing threats to regional water […]
Levels of cadmium, a carcinogen, measured 20 percent higher than the official limit in China’s Longjiang River, Xinhua reported. The pollution, which may have been caused by mining, spurred a rush to buy bottled water amid fears of drinking water contamination. Weather Extremes Floods killed 6 people in Fiji and displaced 3,500 following heavy rains, […]
In the era of deficit and disinvestment, water-intensive fossil fuel production is overwhelming the water-sipping clean energy sector.
Arsenic Arsenic is tainting freshwater supplies in Mexico’s Laguna region, the country’s biggest milk producer, as dairy operations, upstream dams and climate change deplete aquifers, AlertNet reported. In Chile, people exposed to high levels of arsenic in their drinking water during the 1950s have a higher risk of cancer despite subsequent contamination control, according to […]
How can the world feed 9.5 billion people, the projected global population in 2050? The Guardian looks at a mix of new, somewhat radical scientific solutions: commercial algae farms, insects, desert greening and meat grown in a lab. Modernising agricultural technology is the key to boosting China’s food output, according to China’s Premier Wen Jiabao, […]
Vast mineral wealth and growing demand from China are driving a huge mining boom in Mongolia, where the International Monetary Fund predicts the economy will grow an average of 14 percent a year between 2012 and 2016, The Economist reported. The rapid growth could impact the region’s aquifers. The mismanagement of groundwater resources could threaten […]
Geologic time scales are long – too long for the human mind to really comprehend. Over millions, and tens of millions, and hundreds of millions of years, the Earth has changed from something unrecognizable to the planet we see on maps, plastic globes, and photos from space.
Lake Erie and some of its biggest tributary rivers have just the right conditions for Asian carp to make themselves at home, according to a study by scientists with the U.S. Geological Survey, Associated Press reported. The invasive species have infested numerous tributaries of the Mississippi River, including the Illinois River, and are threatening to […]
Decades of groundwater pumping have left one of the San Luis Valley aquifers in a perilous state. To restore its health — and the foundation of the local economy — valley leaders are developing a plan to pay farmers to fallow up to 16,000 hectares. But with commodity prices soaring, will anyone go for it, or will the state have to step in?
