Drought concerns grow in India
Across much of northern India, the Guardian reported, a late monsoon and the driest June for 83 years are exacerbating the effects of a widespread drought, pitting neighbour against neighbour in a fight for water. The United Nations has long warned that water shortages will become one of the world's most pressing problems. India's current situation is seen as a foretaste of the future.
Large Aral Sea shrinks further
The eastern lobe of the disaster-struck Aral Sea seems to have shrunk by four-fifths in just three years, according to the European Space Agency (ESA), Agence France-Presse reported. The central Asian sea – once the world's fourth-largest inland body of water – is now a byword for environmental devastation. It has been retreating for five decades, since rivers that fed it were diverted for Soviet cotton-irrigation projects.
Dams near Yellow River are “fragile”
Chinese news media say several hastily constructed dams on tributaries of the Yellow River in arid north-east China are near collapse shortly after being built, Reuters reported. At least five newly built dams in Huan county, in Gansu province, are “in very fragile condition,” China Daily said, citing a report from the China Youth Daily.
Glacier melt floods Silk Road region
The Chinese gateway to the ancient Silk Road is being flooded due to climate change, New Scientist reported, citing new research. Above the Hexi corridor in Gansu province, scientists said, melting glaciers are contributing to regional floods. The findings are a stark warning for the coming decades: arid regions next to glaciers will face flooding, then dry up completely when the glaciers are gone.
Dam approved for Amazon tributary
Brazil has approved an environmental permit for a hydroelectric dam in the Amazon, Reuters reported, citing an environmental agency official. The decision advances the Jirau dam project, on the Madeira River, which the government hopes will increase power supplies. Critics call it an ecological disaster. The river is one of the Amazon River’s longest tributaries.
West Bank water “unequally shared”
A deepening drought in the Middle East is aggravating a dispute over water resources after the World Bank found that Israel is taking four times as much water as the Palestinians from a shared aquifer, Reuters reported. Although Israelis and Palestinians share the mountain aquifer that runs the length of the occupied West Bank, the World Bank found huge disparities in water use.
Wen again delays Nu River dam work
China’s premier, Wen Jiabao, has again halted work on a controversial dam-building project on the Nu (Salween) River, one of the country’s last free-flowing waterways, the South China Morning Post reported. The newspaper said Wen ordered a halt to work on the Liuku hydropower station in Yunnan Province in April, calling for more environmental assessment.
Mekong dams concern UN researchers
Chinese dam-building on the upper half of the Mekong poses the greatest threat to the future of the river, one of the world’s major waterways and a key regional water source, according to a United Nations report cited by the Associated Press. Laos, too, has begun dam construction on the river and its tributaries, and Cambodia and Vietnam have building plans.
Kenyan parks may get electric fences
Thousands of kilometres of electric fencing are being considered for key national parks in Kenya, along with a doubling of the number of armed guards, to protect water sources and stop people from cutting down trees, the Guardian reported. The moves will be made, according to the Kenya Wildlife Service, as the effects of climate change and other factors become more serious.
