In Peru's deserts melting glaciers are a godsend - until they are gone

Using some of the glacial water to ‘Green’ the Peruvian the desert, as is being done in China and North Africa would be a smart move. See LOESS PLATEAU WATERSHED REHABILITATION PROJECT

Yet climate change now threatens some of these ambitious undertakings, reducing lakes, diminishing aquifers and shrinking glaciers that feed crops. Here in Peru, the government irrigated the desert and turned it into farmland through an $825 million project that, in a few decades, could be under serious threat.

“We’re talking about the disappearance of frozen water towers that have supported vast populations,” said Jeffrey Bury, a professor at the University of California at Santa Cruz who has spent years studying the effects of glacier melt on Peruvian agriculture. “That is the big picture question related to climate change right now.”

A changing climate has long haunted Peru. One past civilization, the Moche people, built cities in the same deserts, only to collapse more than a millennium ago after the Pacific Ocean warmed, killing fish and causing flash floods, many archaeologists contend.

Now dwindling water is the threat. While more than half of Peru sits in the wet Amazon basin, few of its people ever settled there. Most inhabit the dry northern coast, cut off from most rain by the Andes range. While the region includes the capital, Lima, and 60 percent of Peruvians, it holds only 2 percent of the country’s water supply.

The glaciers are the source of water for much of the coast during Peru’s dry season, which extends from May to September. But the icecap of the Cordillera Blanca, long a supply of water for the Chavimochic irrigation project, has shrunk by 40 percent since 1970 and is retreating at an ever-faster rate. It is currently receding by about 30 feet a year, scientists say. https://goo.gl/Wa1JyK

Water Security and U.S. Foreign Policy in India, Pakistan, and the Philippines

In 2012, the U.S. National Intelligence Council judged that within the next 10 years, water problems would be a major contributor to instability in “many” countries that are of interest to the United States. South and Southeast Asia, with its many transboundary river basins, large populations, and geopolitical flashpoints, is one among a number of hotspots where such instability could occur.

To help policymakers understand the implications of water problems for national security, World Wildlife Fund-U.S. is working with global experts to produce a book highlighting water conflicts and U.S. strategic interests. Four experts spoke at the Wilson Center on May 9 about the dynamics at play in India, Pakistan, and the Philippines.

The World Economic Forum’s 2016 risk survey ranked water crisis as the top risk globally in the next decade. Among experts, there is growing concern about water issues and state fragility. “When government fails to provide basic water services, when they fail to protect the people against drought and flood, fail to preserve water resources captured by the elites, there is a potential loss of legitimacy and an opportunity for other parties to exploit those failures and deepen the instabilities,” said Claudia Sadoff, the World Bank’s global lead for water security and integrated resource management.

It is essential and urgent to “design and prioritize water programs that will lead to stability, development, and prosperity,” she said.
