Climate change is likely to blame for a massive avalanche in Tibet that killed nine people in July, according to an analysis of the distaster published Dec. 9 in the Journal of Glaciology. More than 70 million tons of ice broke off from the glacier capping the Aru Mountains of western Tibet's Rutog county on July 17, covering 9.6 square kilometers (3.7 square miles) of the valley floor in just four or five minutes and killing nine nomadic yak herders. The study was undertaken by researchers from the Chinese Academy of Sciences and a US team including Lonnie Thompson of the Byrd Polar and Climate Research Center, who has done simiiar work in the Andes. The team found that melted water at the glacier's base must have lubricated the ice, speeding its path down the mountainside. "Given the rate at which the event occurred and the area covered, I think it could only happen in the presence of meltwater," said Thompson, adding that other nearby glaciers may now also be vulnerable. "Unfortunately, as of today, we have no ability to predict such disasters."

The US Army Corps of Engineers on Dec. 4 issued a statement saying that Dakota Access LLC will not be granted the last remaining easement it needs to drill under the Missouri River at Lake Oahe and complete construction of the Dakota Access Pipeline. The statement considers the possibility that the Army Corps will conduct a limited Environmental Impact Statement (EIS) on the river crossing and explore possibilities for alternative routes. The decision comes as after weeks of protests at the crossing site, and as thousands of veterans are arriving from across the country to stand with the self-declared "water protectors" who face escalating repression at the hands of law enforcement.

More than 140 were arrested Oct. 27 as over 300 police officers in riot gear—backed up with several armored vehicles and two helicopters—cleared the camp erected to block construction of the Dakota Access Pipeline. North Dakota's Gov. Jack Dalrymple used emergency powers declared over the protests in August to bring in officers from neighboring states.  The 1851 Treaty Camp was set up directly in the path of the pipeline, on private land recently purchased by Energy Transfer Partners, the company building the pipeline. But the land has been declared reclaimed as tribal territory by the Standing Rock Reservation under the Fort Laramie Treaty of 1851. The Morton County sheriff’s department said protesters torched several police vehicles, and that two officers were lightly wounded. Those arrested were not allowed to post bail. The sweep brought the total number arrested in the protests since August to 411. State officials have stated that they will no longer communicate with the protesters.

Luiz Alberto Araújo, who headed the environment department for the municipal government of Altamira in Brazil's Amazonian state of Pará, was killed by two unknown gunmen Oct. 13. The assailants drove up to his car and fired nine shots into him, in front of his wife and two step-sons. Nothing was stolen and the killing is believed to have been a political assassination. In his endeavors to enforce environmental legislation in the largely lawless Amazonian region, Araújo made powerful enemies. Earlier this year, he provided information to the Federal Police and Federal Public Ministry that prompted them to launch Operaçāo Rios Voadores (Flying Rivers Operation). This crackdown on illegal logging enterprises led to 24 arrests—including that of the ring-leader, Antonio José Junqueira Vilela Filho, known as AJJ. He and his son were accused of illegally invading rainforest lands, extracting valuable timber, and clearing the remaining forest and turning it into cattle pasture.

Peru's National Forestry and Wildlife Service (SERFOR) is investigating the death of some 10,000 frogs whose bodies have been found in the Río Coata, which flows into Lake Titicaca. The alert was sounded by the local Committee Against the Pollution of the Río Coata, which accused the authorities of ignoring the river's severe pollution. Activists brought 100 of the dead frogs to the central square in the regional capital, Puno. Said protest leader Maruja Inquilla: "I've had to bring them the dead frogs. The authorities don't realize how we're living. They have no idea how major the pollution is. The situation is maddening." The committee has long been petitioning for construction of a sewage treatment plant for the river, and also for bringing informal minig camps up the river under control. Last year, arsenic, presumably from unregulated gold-mining in the area, was found to have contaminated several wells in the Coata watershed. The Puno regional health department conducted the study following a campaign by local campesino communities. 

The International Criminal Court released a policy document Sept. 15 calling for prosecution of individuals for atrocities committed by destroying the environment. The document, prepared by chief prosecutor Fatou Bensouda, sets out the types of cases that the court will now prioritize, including willful environmental destruction, illegal exploitation of natural resources, and "land grabbing." The ICC has already shown a willingness to apply its authority to situations involving environmental destruction. Between 2009 and 2010, then-prosecutor Luis Moreno Ocampo successfully obtained arrest warrants from the court against the president of Sudan, Omar al-Bashir, for acts of genocide, war crimes and crimes against humanity. Among other acts, these alleged crimes involved the contamination of wells and destruction village pumps in Darfur to deprive targeted populations of water. Al-Bashir's trial has not yet commenced as he continues to evade arrest. (The Conversation, Sept. 23)

India's highest court ordered (PDF) the state of Karnataka to share water with the neighboring state of Tamil Nadu on Sept. 12. The two states have disputed rights to the Cauvery River for decades. Last week the court ruled that Karnataka must share 15,000 cubic feet per second for 10 days, but Karnataka appealed that decision. Karnataka officials argued that the state does not have enough water to share and that Tamil Nadu is not suffering hardship over the water. The court ordered Karnataka to release 12,000 cubic feet per second instead of 15,000. After the decision violent protests erupted which led to attacks on hotels, shops, and buses. In response, police deployed 15,000 officers to the area and are prohibiting large public gatherings.

Communal farmers from the pueblo of San Pedro Apatlaco in Mexico's Morelos state clashed Aug. 30 with federal riot police at a protest over construction of an aqueduct bringing water to a new gas-fired power plant under construction at nearby Huexca, Yecapixtla municipality. The clash took place as police tried to clear a bridge the protesters were occupying, linking the municipalities of Cuautla and Ayala through Apatlaco pueblo (which lies in Ayala). The farmers were attempting to bar a crew from the Federal Electric Commission (CFE) from blocking off a common area long used by residents for the aqueduct right-of-way. Troops from the new federal anti-riot force, the Unified Command (Mando Unico), were brought in to clear the bridge. Some 15 protesters were detained, with injuries reported on both sides. Opponents say the aqueduct will pass through more than 100 eijidos (agricultural collectives) and communcal lands, and that the affected communities were not consulted. There were similar protests two years ago over construction of the gas pipeline feeding the plant, part of the Morelos Integral Project (PIM).
