What California’s Dam Crisis Says About the Changing Climate

What California’s Dam Crisis Says About the Changing Climate - The New York Times

STANFORD, Calif. — After five years of record-setting drought, much of California is being pummeled by an extremely wet winter. The disaster unfolding at Oroville, where precipitation is more than double the average, is the latest reminder that the United States needs a climate-smart upgrade of our water management systems.

In the West, much of our water infrastructure is old. Oroville Dam, north of Sacramento, was completed in 1968, nearly a half a century ago. Other major components of our water system are generations older, and maintenance has not been a priority. The damage to Oroville Dam, where the primary spillway developed a giant gash and the emergency spillway threatened to erode, illustrates the hazard of relying on aging infrastructure to protect us from extreme weather. http://nyti.ms/2lLbg6D

Alpacas trump sheep in bid for Andean water security

Alpacas trump sheep in bid for Andean water security

TEPIC, Mexico, Feb 8 (Thomson Reuters Foundation) - High on Ecuador's Andean plains, the Comuna Espejo co-operative is counting on a recent delivery of 20 woolly alpacas to keep its moist grasslands in better shape than the sheep that normally graze there - and in turn help secure water supplies to the nearby capital city of Quito.

“Little by little, we're going to see the impact the alpacas have, but they're easier to manage than sheep and the degradation is less,” said Henry Carrera, vice president of Comuna Espejo, now home to 18 female and two male alpacas.

Besides selling wool, and eventually meat from the camelids, Comuna Espejo hopes to attract tourists with the alpaca project, which forms part of the Quito Water Fund’s plans to conserve the watersheds around the city some 30 km (19 miles) away.

Quito’s fund, the first to be set up under the auspices of U.S.-based environmental group The Nature Conservancy (TNC) in 2000, has provided a model for nearly 60 cities around the world to boost water security from the source to the sink.

The funds combine scientific expertise with public and private-sector investment from water authorities, banks and large water users such as bottlers and brewers.

Now TNC has 20 funds active in Latin America. It plans to double these by 2020 in the region where 80 percent of the population lives in cities, putting huge pressure on water supplies.

“Being able to protect the water sources for the cities is very important for the population, to reduce risks for water quality and quantity,” said Silvia Benitez, TNC’s Quito-based fresh water manager for Latin America.
