Related: About this forumPeru Trying To Keep Up With GLOF Warning Systems; Water Acidifying, New Pests Appearing At Altitude
Villagers in Pariacaca watch a presentation about Perus first early warning system, which monitors glacial lake 513, located above their village. In 2010, they managed to escape a landslide precipitated by an ice avalanche into the lake because they had constructed tunnels to drain off extra water. As the glaciers melt, the excess meltwater will cause more floods in downstream villages such as Pariacaca. Now, with technical assistance from the University of Zurich and Swiss aid, the solar-powered early warning system allows them to sleep more easily at night
Farmer Alejandro Cruz measures the pH of the Black river, which is turning increasingly red due to acidic iron oxide deposits. An unexpected side-effect of the glacial retreat is the acidification of the meltwater, as the withdrawing ice exposes metal-rich rocks to the air for the first time in tens of thousands, or even millions, of years
After heavy rainfall, the pH reading of the river water stands at 4.9 (highly acidic, for water). Cruz and his farming community are working with scientists to use local plants to counteract the heavy metals in the meltwater. Certain plants have an 'extraordinary capacity to absorb metals', says Raul Loayza, an aquatic toxicologist at Limas Cayetano Heredia University. Cruz and his fellow farmers are beginning to tailor the existing highland wetlands which act like slow-release sponges for glacial meltwater to combat the deteriorating quality of the water as well as storing it
'We never used to have pests at 3,500 metres above sea level, but now that its warmer at this time of year, we do,' says Salvador. 'Some farmers are starting to use insecticide for the first time,' he adds. Farmers in the Cordillera Blanca are now learning about irrigation from farmers in the Cordillera Negra on the other side of the Santa valley. They are preparing for a time when there will be less water, both in quantity and quality after the glaciers have melted

(208 posts)1. Vested Petroleum interests ignore Climate Impact
Thanks for this post, Hatrack.
Vested Political interests put up a pretense, simply won't be convinced of "Climate Change" regardless of supporting evidence since admission of uncontrolled "Carbon Footprint" impact would lead to tightened restrictions, control of Corporate waste, related regulatory enforcement.
THAT would obviously disrupt their cash flow from the Petroleum Industry.
But supposing they'd pay attention to an objective, non-political 3rd party, NOAA disagrees with their conflicted, contrived public pronouncements of supposed "Climate Change Hoax".
