Peru's central government is pouring troops into the rainforest region of Madre de Dios in an all-out effort against thousands of illegal gold-miners operating in remote areas. Under "Operation Mercury"—named for the mercury poisoning caused to local waters by the mining—three High-Mobility Temporary Mixed Bases, manned by military and National Police personnel, are to be established in the area of La Pampa, within the buffer zone of Tambopata National Reserve. Cabinet officials were flown into the remote area March 5 to inaugurate the first base, dubbed "Alpha." On hand were Defense Minister José Huerta, Interior Minister Carlos Morán and Environment Minister Fabiola Muñoz. Each base is to have 100 soldiers, 50 police agents and a public prosecutor. In the first phase of the operation, launched last month, authoritiies "rescued" 51 people from the mining camps, detained 80, and confiscated millions of dollars in prperty.

An indigenous environmental activist was killed in Mexico's south-central state of Morelos on Feb. 20—three days ahead of a planned referendum on an energy development project that he opposed. Samir Flores Soberanes was a leader of the local Peoples in Defense of Land and Water Front (FPDTA) and community radio station Amilzinko. He was slain by unknown gunmen in an attack at his home in the village of Amilcingo, Temoac municipality. He was a longtime figure in local opposition to the planned Huexca power plant and associated natural-gas pipeline, pushed by the government under the Morelos Integral Project (PIM).

Rising temperatures in the Himalayas will melt at least one-third of the region's glaciers by the end of the century even if the world's most ambitious climate change targets are met, according to a new report. If those goals are not reached, the Himalayas could lose two-thirds of their glaciers by 2100, according to the Hindu Kush Himalaya Assessment, released Feb. 4 by the Kathmandu-based International Centre for Integrated Mountain Development. Under that scenario, the Himalayas could heat up by 8 degrees Fahrenheit (4.4 degrees Celsius) by century's end, bringing radical disruptions to food and water supplies, and mass population displacement. Glaciers in the Hindu Kush-Himalayan Region, which spans over 2,000 miles of Asia, provide water to nearly a quarter of the world's population.

On his first day in office Jan. 2, Brazil's President Jair Bolsonaro issued a provisional measure (Medida Provisório 870) taking away responsibility for indigenous land demarcation from the indigenous affairs agency, FUNAI, and handing it over to the Agriculture Ministry. In the same decree, Bolsonaro shifted authority over regularization of quilombos (lands titled to runaway slave descendants) from the agrarian reform institute, INCRA, to the Agriculture Ministry. The measure greatly weakens FUNAI, taking away its most important function. In practice, key areas of indigenous and quilombo policy will now be in the hands of agribusiness advocates—a long-time demand of the Bancada Ruralista (agribusiness bloc) in Congress.

A settlement of semi-nomadic Fulani herders was attacked in Mali Jan. 1, with at least 33 residents slain and several homes set aflame. Survivors said the attackers were traditional Dogon hunters, known as dozos. The army was rushed to Koulogon village in central Mopti region to control the situation following the massacre. But the perpetrators may have actually been assisted by the armed forces. Dogon residents of the area have formed a self-defense militia, known as Dana Amassagou (which translates roughly as "hunters in God's hands"), to prevent incursions by jihadists from Mali's conflicted north into the country's central region. The militia is said to have received weapons and training from the official armed forces. However, driven by conflicts over access to land and shrinking water resources, the militia has apparently been attacking local Fulani villages. Hundreds are said to have been killed in clashes between Dogon and Fulani over the past year. A Senegalese rapid reaction force under UN command was deployed to Mopti last year in response to the mounting violence.

A court in Honduras convicted seven men in the 2016 murder of indigenous rights activist Berta Cáceres on Nov. 29. Until her assassination on March 2, 2016, Cáceres had been leading a campaign against the Agua Zarca dam in western Honduras, a joint project by Honduran company Desarrollos Energéticos SA (DESA) and Chinese-owned Sinohydro. The dam was being built on the Rio Gualcarque without prior consultation with the Lenca indigenous community that depends on the river for their food and water. Cáceres, who won the prestigious Goldman Environmental Prize in 2015, had received numerous threats for her activism against the dam before she was killed by gunmen at her home in the town of La Esperanza. Mexican environmentalist Gustavo Castro was also shot, but he survived the attack. Two of those convicted are former DESA managers.

Brazil's far-right president-elect Jair Bolsonaro campaigned on a plan to privatize vast swaths of the Amazon rainforest, turning it over to agribusiness and mining. In addition, he seeks to expand hydro-power and other energy mega-projects the region. Since his election in an Oct. 28 run-off vote, Bolsonaro's team has announced that his administration will merge the ministries of agriculture and the environment into a new "super ministry" to oversee the plan. Brazil now has some 720 indigenous reserves, ranging in size from a single hectare to nearly ten million hectares. Bolsonaro has said he wants to put all of those lands—13% of Brazil's territory—on the auction block. "Minorities have to adapt to the majority, or simply disappear," he said on the campaign trail, adding that under his administration, "not one square centimeter" of Brazil will be reserved for the country's indigenous peoples.

The Supreme Court of Canada ruled Oct. 11 that the federal government does not have a responsibility to consult with First Nations before introducing legislation, even in cases when it would impact their lands and livelihood. The 7-2 ruling in Chief Steve Courtoreille et al vs Governor in Council et al ends a challenge by the Mikisew Cree First Nation of Alberta to a 2013 reform of Canada's environmental laws by the administration of then-prime minister Stephen Harper. The reform altered the Canadian Environmental Assessment Act, the Fisheries Act, the Species at Risk Act, and the Navigable Waters Protection Act, reducing the number of projects that require environmental assessment studies and narrowing the scope of those assessments. The Mikisew Cree contended that the reform violated constitutionally-protected treaty rights of Canada's indigenous First Nations.
