Glaciers Are Nature’s Reservoirs
Dec 15th, 2009 by admin
The New York Times has an article up today about the impact of global warming on the glaciers and water supply of the area surrounding La Paz and El Alto in the Andes of Bolivia. It’s a timely piece, as climate-change talks in Copenhagen are in tumult after poorer nations threatened to walk out over the richer nations’ reluctance to curb enough greenhouse emissions and contribute more to infrastructure improvements for the rest of the world.
La Paz and El Alto depend on the surrounding glaciers to act as natural reservoirs, which in the past stored water–as ice–in the dry season, slowly melting and supplying water for the millions of people living in the cities and countryside. Now, with the glaciers in retreat, water runs freely down the mountains, and the dry season is now truly dry.
Developed countries agree that they have an obligation to help relieve such stresses, but many remain hesitant to release funds, in part because poor countries have few concrete plans to address climate problems. The effects of climate changes have not yet been analyzed or quantified by Epsas, the water company, for example.But with little cash or expertise, it is hard to plan a giant new reservoir or a system to transfer water from one part of the country to another. Bolivia’s poor, said Edwin Torrez Soria, an engineer with Aqua Sustentable, who works with villages near the Illimani glacier, “aren’t responsible for what’s happening to the glacier but they suffer the most, and unfortunately the government doesn’t have much of a plan.”
