Next to water, sand is our most consumed natural resource. The global demand for sand and gravel stands between 40 billion and 50 billion tonnes annually, according to the United Nations Environment Program (UNEP), and its scarcity is an emerging global crisis. The world may run out of sand if we ...

Fishermen in northeast Thailand say they have seen catches in the Mekong River plunge, while some farmers in Vietnam and Cambodia are leaving for jobs in cities as harvests of rice and other crops shrink. The common thread driving these events is erratic water levels in ...

A recently published report by Eyes on Earth, Inc. has pointed the finger at Chinese dams holding back water as having significantly contributed to the major drought impacting the Mekong River in Southeast Asia. The drought’s effects have been felt by millions and hamper efforts to ...

The Mekong River Commission(MRC) yesterday said the water levels across the vast majority of lower Mekong basin have now returned to their normal long-term averages.

China’s upstream activities along the Mekong River have long been contentious — but a recent study has sparked fresh scrutiny over its dam-building exercises, reigniting warnings that millions of livelihoods could be destroyed. A U.S.-government funded study by research and consulting firm, Eyes on Earth, found that Chinese dams ...

As the Tonle Sap floodplain empties into the Mekong this spring, the Cambodians who rely on these waters face bleak prospects, with fish catches reportedly 10 to 20% of previous years. Blame for the precipitous decline in the ecology has been put on the many hydropower projects ...

Southeast Asian countries would have likely experienced a much less severe drought last year if it were not for China’s dams, a new study says, prompting a pushback from the intergovernmental Mekong River Commission (MRC). The 4,000-km (2,485-mile) Mekong is one of the world’s longest rivers – ...

Cracked riverbeds, empty fishing nets and, snaking its way through the parched landscape, a beautifully clear, blue-tinted river.
