PERU fishing with guts to report…
The National Water Authority (ANA) warned the risk to the city of Huaraz, Ancash Region potential overflow of Laguna Palcacocha due to deglaciation process is recorded in the Cordillera Blanca as a result of climate change.
Judith Torres Specialist Unit Glaciology ANA, said the National Center for Estimation, Prevention and Disaster Risk Reduction (CENEPRED) has already issued 11 states of emergency on Laguna Palcacocha.
“Because this gap is increased contact with glacier mass and volume has increased dramatically compared to 2003 to present”He remarked.
He said there are plans to strengthen the dam this gap in order that the population of the city of Huaraz is safer.
He argued that the risk of overflow is still much higher in countries like Peru where seismic activity is quite strong.
“Therefore it is likely that breakthroughs glaciers which these gaps may fall, causing large waves or breaks levees, running to major cities in Ancash, which is most prone to these threats occur”, he said.
He recalled that in 2010 a block of ice snow fell Hualcán Lagoon 513, generating a wave of more than 20 meters, alarming Carhuaz populations and Acopampa.
It was precisely because of this experience that the Glacier project was developed with support from the Swiss Cooperation and CARE Peru, to install an early warning system in the City of Carhuaz (Ancash), as the region near the Cusco, cone largest glacier area in Peru.
“This early warning system allows us to plan and have an awareness of warning about these gaps overflows or floods”, he stressed.
The specialist also said that another risk of this deglaciation is the lack of availability of fresh water in the 26 glacial basins of Peru, because agricultural activities will suffer detriment of water resources.
“Populations that are downstream of the basins are prone to overflows probable gaps, landslides that may occur due to rupture of small masses glaciers as occurred in 1970 with the peak Huascaran”He noted.
He acknowledged that at first may feel benefit populations with large amounts of water generated by the deglaciation, but long-term gaps are not going to get the water supply because it will no longer have glaciers.
“Probably they will be fed by rainfall, but we are very particular situations can vary by climate change. Mostly affected are to be glacial basins where populations live”He argued.
