In the decades ahead, global warming will inexorably alter the ways humans live. Many in the Pacific will have to migrate en masse as the islands they live on disappear beneath the rising sea. Those who live in subtropical areas will have to deal with stronger and more frequent cyclones.
Life in a changed climate will mean a new emphasis on the importance of that natural resource fundamental to human life: water. Control of it will be a point of even greater contention in many parts of the world.
In Southeast Asia, control of the Mekong river is becoming an international wrangle of possibly greater significance than the one in the South China Sea.
While the maritime row centers on the possession of strategic specks of barely inhabited islands and what natural resources may exist nearby, the riverine dispute affects 30 million people in mainland Southeast Asia.
Rising in the Tibetan plateau and emptying into the South China Sea, the Mekong passes through five Southeast Asian countries: Myanmar, Laos, Thailand, Cambodia and Vietnam.
In each country it passes, the 4,350-km-long river plays a pivotal role.
In Myanmar, the Mekong runs through contested areas controlled by armed ethnic militias. The river then defines most of the border between Thailand and Laos and sustains Cambodia through its great lake, the Tonle Sap. Further downstream, sediments enrich the fertile soil of Vietnam’s Mekong Delta.
The low-lying delta region is home to 20 million people—a fifth of Vietnam’s population—and is under threat of inundation from the rising sea. Long before that problem will appear, however, dozens of dams built along the Mekong are adversely affecting its flow and creating a water crisis downstream.
Electricity generation plans by Laos and China, as our first opinion article by Brahma Chellaney outlines, are the main driver of this dam construction.
While the resulting electricity is meant to benefit regional countries through the ASEAN Power Grid, Cambodia and Vietnam are objecting to more dams.
Diplomacy has so far failed to bring about an enduring international understanding on the Mekong.
The intergovernmental Mekong River Commission (MRC) has proven ineffective in bringing China and Myanmar to the negotiating table. A second, China-led initiative, the Lancang-Mekong Cooperation, is making progress instead. Cambodia will host its second summit this week.
Our second opinion article by the Bangkok-based Nation is taking a skeptical stance. For good reason. The political preferences of attending countries make the upholding of the 1995 international treaty on the Mekong, which the MRC advocates, unlikely.
So, where does that leave us? Climate change and its attendant problems loom over the horizon. Water-related crises are unfolding in downstream countries of the Mekong and fast-growing economies of Southeast Asia have legitimate needs for electricity.
It is evident that what we need is political will to work together and negotiate on how to share the bounties of the Mekong.
