Campesinos occupying the contested Conga mine site in Peru's Cajamarca region on Aug. 20 tore down a gate they said had been illegally erected by the Yanacocha mining company across a trail used by locals as a traditional right-of-way. Video footage shows protesters using shovels and farm implements to tear up and drag away the metal gate across the pathway near Laguna Namocoha, one of the highland lakes that will be impacted by the mining project. National Police troops on hand apparently did not interfere. Idelso Hernández, leader of the Cajamarca Defense Front, challenged police and prosecutors to attend a campesino assembly to answer for allowing construction of the gates. Protesters said that if their demand for a meeting on the matter was not met, they would similarly take down two other gates built by the company blocking access to lagunas Azul and Cortada. (Celendin Libre, Aug. 20; video footage at Celendin Libre, Aug. 20)

Over 100 ethnic Tibetans were injured and one man committed suicide in Yulshul (Chinese: Yushu) prefecture* in the Kham region of Eastern Tibet (officially in Qinghai province), as Chinese military forces broke up protests against diamond mining in the area Aug. 19. As in similar protests elsewhere in Qinghai earlier that week, protestors put up large banners printed with President Xi Jinping's recent speech on environmental protection, and charged that the mines have not been approved by China's central government. The clash apparently began when some 1,000 protesters occupied two traditional Tibetan sacred sites, identified as Atod Yultso and Zachen Yultso, at a mine in Dzatoe (Chinese: Zaduo) township, and security forces fired tear-gas to disperse them. Eight protesters were detained, but two identified as leaders are reported to have "disappeared."

The unfinished Pascua Lama gold and silver mine high in the Andes on the Chilean-Argentine border continues to bring problems for Toronto-based Barrick Gold Corp. The multinational has announced a loss of $8.56 billion for the second quarter of this year, largely because of a $5.1 billion write-down of the mine's value. The $8.5 billion project is stalled because of environmental concerns and legal actions in Chile. Suspension of construction at the mine coincided with a record 23% drop in international gold prices from April through June.

Peru's Supreme Court ruled Aug. 16 that decrees on application of the Prior Consultation Law recently issued by the Energy and Mines Ministry are unconstitutional. The legal challenge was brought by the nongovernmental Legal Defense Institute (IDL), which argued that the Ministry's guidelines called for "informational workshops" rather than a decision-making process. The high court agreed that the guidelines failed to conform with the International Labor Organization's Convention 169, which outlines standards for the rights of indigenous peoples. Peru ratified Convention 169 in 1994. The guidelines, principally concerning oil and mineral development, are voided by the ruling. (Gestión via No a la Mina, Aug. 17; La Republica, Aug. 16)

India's Dongria Kondh tribe have overwhelmingly rejected plans by British mining giant Vedanta Resources for an open-pit bauxite mine on their sacred lands, in an unprecedented triumph for indigenous rights on the subcontinent. Twelve Dongria villages unanimously voted against Vedanta's mine during consultations ordered by India's Supreme Court in April. The court based its ruling on the Dongria people's religious, cultural and social rights. The mine would destroy the forests and disrupt the rivers in the Niyamgiri Hills of Orissa state, which are central to the livelihood and identity of the 8,000-strong tribe. Advocates charged the mine would spell the end of the Dongria as a self-sufficient people.

An activist tribunal dubbed the Ethical Trial against Plunder (Juicio Ético contra el Despojo) was held in Bogotá over the weekend to air testimony against the practices of multinational gold firm Anglo Ahshanti (AGA) and oil giant Pacific Rubiales Energy (PRE). More than 500 representatives from across Colombia convened in the capital's central folk-crafts market, the Plaza de los Artesanos, to present evidence that the multinational corporations were involved in the murder of union leaders, displacement of indigenous communities, and grave environmental damage. The objective was to gather enough evidence to be able to put forward an real legal case.

Ethnic Tibetans protesting what they called illegal mining operations clashed with Chinese security forces in Gedrong Zatoe county, Qinghai province, Aug. 16. Exiled Tibetan activists with contacts in the region told Phayul news service that the protesters have pledged to block the mining operations, citing the threat to local watersheds. Hundreds of troops arrived at the three townships  where protesters were mobilzing, and issued an "ultimatum" to call off the campaign or face arrest. Local Tibetan leader Khentsa Soedor reportedly said, "You can kill us but we will not let the mining take place here. It is our responsibility to protect our environment which is a source of water to many other countries." Authorities detained Soedor's wife for interrogation, and his whereabouts are now unknown.

The area of land planted with coca leaf in Colombia has fallen by 25%, and is now about a third of that in 2001, according to the latest report from the UN Office on Drugs and Crime (UNODC)'s Integrated Illicit Crops Monitoring System. The report finds that land planted with coca has dropped from 64,000 hectares in 2011 to 48,000 hectares in 2012, the lowest figure since monitoring started in Colombia more than a decade ago. Although the National Police actually eradicated less coca than in previous years, the force increased its presence in coca-growing regions, apparently preventing campesinos from planting coca in the first place. But while coca areas fell nationwide, they rose in three departments still especially wracked by armed conflict—Norte de Santander, Chocó and Caquetá.
