A new study published in Science finds that a critical glacier in the Peruvian Andes has shrunk to its smallest extent nearly since the end of the last Ice Age. Ohio State University glaciologist Lonnie G. Thompson is studying plants that have been recently exposed near Quelccaya Ice Cap, the world's largest tropical ice sheet, located 18,000 feet above sea level (straddling the border of Cuzco and Puno regions). Chemical analysis of plants exposed by melting several years ago showed them to be about 4,700 years old, proving that the ice cap had reached its smallest extent in nearly five millennia. In the new findings, a thousand feet of additional melting has exposed plants that lab analysis shows to be about 6,300 years old. Thompson said this indicates that ice that had accumulated over approximately 1,600 years melted back in no more than 25 years.

On Nov. 11, the Second National Congress of Artisanal Miners was held at Juliaca, in Peru's southern region of Puno, presided over by Hernán de la Cruz Enciso, AKA Tankar Rau Rau Amaru, outspoken president of the National Confederation of Artisanal Miners and Small Producers (CONAMI), pledging to launch new road occupations if the government does not rescind decrees mandating the "legalization" of informal mining operations. A surprise guest was Walter Aduviri, leader of the Aymara campesino struggle in Puno, who has led strikes and protests against mining projects. De la Cruz and Aduviri shared a public abrazo (embrace) and hailed the meeting as "a step towards the consolidation of objectives" of their respective movements. De la Cruz said Aduviri "is against big mining and supports small mining." Peru's pro-business website eeé (for Economy & Energy with Ethics [sic]) on reporting the meeting, added: "Peruvians are now notified of this new alliance of terror and violence, between Tankar Rau Rau Amaru (Hernán de la Cruz) and Walter Aduviri."

More than 500 residents in the campesino community of Tumpa in Yungay province of Peru's central Andean region of Áncash, began blocking roads leading to the local operations of the Mina California company Aug. 6, declaring an open-ended paro (civil strike) to demand a halt to the mine's pollution of local waters. The mine is located near Nevado Huascarán, Peru's highest mountain, and the national park of the same name, which forms the headwaters of several of Peru's major rivers. (Servindi, Aug. 6) That same day, Aymara indigenous residents of Acora community in Puno region announced that a 72-hour paro will begin Aug. 13, to protest President Ollanta Humala's plans to move ahead with the Pasto Grande II irrigation project. The Pasto Grande II project would divert waters from the Lake Titicaca basin for agribusiness tracts on the coast in Moquegua region. The strike, called by the South Puno Natural Resources Defense Front, will also protest contamination of local waters by mining and other extractive industries.
