Drought: Hydropower’s Achilles Heel

Drought: The news has been full of it.

Fish are disappearing from markets from Zimbabwe to Vietnam because of it. Kenyan barristas are making “camelcinos” because drought has made cow milk scarce. And in India, men from some villages are even finding it hard to get wives because the water shortage makes them look like a bad bet.

Across Asia, Africa and Latin America, the rains are not falling – they’re failing.

But drought is no longer just a concern for farmers; it’s increasingly becoming a major humanitarian and political issue, particularly in hydropower-dependent countries.

Southeast Asia’s Rivers Run Dry

The dry months before the monsoon rains arrive are often tough for Cambodian fishermen and farmers. But with rivers drying up and drinking water running out, conditions have rarely been as bad as they are now.

The current drought is linked to El Niño, which has been disrupting weather patterns around the world. But the harsh conditions today might only be foreshadowing far worse to come, climate scientists say. Climate change is expected to continue to affect the Mekong Basin region, while future droughts are expected to be exacerbated by a string of major hydropower dam projects.

Experts fear that the present crisis could become the new normal for Cambodia and its neighbors, which have also been hit hard by record temperatures and a long period of extremely dry weather.

Mekong Dams Not Cause of Drought

Prime Minister Hun Sen on Monday disputed the idea that water shortages along the Mekong River have been exacerbated by two massive hydropower dams being developed by Laos, saying the drought currently afflicting much of mainland Southeast Asia was caused only by “the sky.”
