An indigenous Mexican ecological defender is now in his seventh month behind bars, despite calls for his relase from Amnesty International, Greenpeace and other human rights and environmental groups. Ildefonso Zamora was arrested by México state police last November, in connection with a 2012 robbery. But Amnesty finds "the charge is unsubstantiated and seems to be politically motivated." A leader of the Tlahuica indigenous people, Zamora served as president of the communal lands committee at his pueblo of San Juan Atzingo. In this capacity, he had long protested illegal logging on usurped communal lands in México state's Gran Bosque de Agua—which protects the watershed that supplies Mexico City. Amnesty notes that the prosecution's witnesses described the events "using the exact same words, as if reading them from a script." The rights group says this points to fabricated testimony, and demands that he be immediately and unconditionally released.

UK-based indigenous rights advoacy group Survival International has launched a campaign to prevent the annihilation of tribal peoples in Brazil, to coincide with the 2016 Olympic Games in Rio de Janeiro. Despite the political chaos currently engulfing Brazil, the campaign aims to bring attention to serious human rights issues and threats facing the country's indigenous peoples. Survival states: "These threats persist regardless of the political turmoil in the country." The campaign, "Stop Brazil's Genocide," focuses on protecting "uncontacted" tribes of the Amazon such as the Kawahiva people; ending violence and land theft directed against the Guarani in southern Brazil; and stopping PEC 215, a proposed constitutional amendment that would undermine indigenous land rights and spell disaster for tribes nationwide.

Michael T. Klare has a piece on TruthDig about last month's OPEC meeting in Doha, Qatar, where high expectations of a boost to chronically depressed prices were dashed: "In anticipation of such a deal, oil prices had begun to creep inexorably upward, from $30 per barrel in mid-January to $43 on the eve of the gathering. But far from restoring the old oil order, the meeting ended in discord, driving prices down again and revealing deep cracks in the ranks of global energy producers." Klare acknowledges the geopolitical factor in keeping prices down: "Most analysts have since suggested that the Saudi royals simply considered punishing Iran more important than lowering oil prices. No matter the cost to them, in other words, they could not bring themselves to help Iran pursue its geopolitical objectives, including giving yet more support to Shiite forces in Iraq, Syria, Yemen, and Lebanon." But he sees market forces and the advent of post-petrol technologies as more fundamental...

Afro-Colombian protesters who were demonstrating on the Pan-American Highway in southern Cauca department to oppose illegal mining on their lands were violently dispersed by riot police April 27. The feared National Police riot squad, ESMAD, used tear-gas and rubber bullets to clear the roadway, leaving several injured, including women, children and elders. Some 2,000 people from over 40 communities in north Cauca took part in the action to protest that "Afro-descendant territories continue to be under threat from multinational mineral companies and illegal mining."

On May 2, authorities in Honduras arrested four people in connection with the March murder of environmental activist Berta Cáceres. As part of an operation code-named "Jaguar," police arrested the four in different locations around the country, including the capital Tegucigalpa. Two were members of the security forces: Mariano Chávez, a Military Police major; and Edilson Duarte Meza, a retired military officer. The two others were linked to the Honduran company that is building the Agua Zarca dam on the Río Gualcarque, which Cáceres was leading the campaign against: Sergio Rodríguez Orellana, a manager for social and environmental issues with the company, Desarrollos Energéticos SA (DESA); and Douglas Geovanny Bustillo, a former security guard hired by DESA for the dam project.

Nearly 15,000 converged on Guatemala City on Earth Day, April 22, the culmination of a cross-country march by peasants and popular organizations to demand local rights over access to water. Marchers set out April 11 from Tecun Uman in the southern coastal department of San Marcos, and from Puruhá, Baja Verapaz, in the central highlands. The March for Water, Mother Earth, Territory and Life was called to "defend water resources against the voracity of agro-industry and extractive industry," according to a statement form the indigenous organization Winaq. The statement said the movement "condemns the abusive, inhuman and impune use of by companies linked to agro-industry and extraction of metals, and the commercialization of the same." The statement called access to water an "elemental human rights," and called for it to be enshrined in Guatemala's constitution.

The planned São Luiz do Tapajós mega-dam in Brazil's Amazonian state of Pará received a significant setback April 20 when its license was suspended by the Brazilian Institute of the Environment and Renewable Natura Resources (IBAMA). The move came in response to a report published by Brazil's National Indian Foundation (FUNAI), declaring "the infeasibility of the project from the perspective of an indigenous component." Some 10,000 Munduruku people live along the Rio Tapajós, and the flooding of their territory by the dam would necessitate their relocation—which FUNAI found to be in violation of Brazil's constitution. In the report, FUNAI recommends the demarcation of 1,780 square kilometers of indigenous Munduruku territory, known as Sawré Muybu, in the area that would be impacted by the project. The 8,000-megawatt São Luiz do Tapajós dam would be Brazil's second largest, after the controversial Belo Monte plant, which finally began operating this week after years of protests by the Munduruku and other peoples.

Human rights group Global Witness last month released figures naming Honduras as the most dangerous country for environmental defenders, based on a finding of at least 109 killed there between 2010 and 2015 "for taking a stand against destructive dam, mining, logging and agriculture projects." The report of course noted the March 3 slaying of Berta Cáceres, a leader of indigenous environmental group COPINH. But this was only the latest in a string of such slayings. Another COPINH member, Moisés Durón Sánchez, was murdered in May 2015 after receiving death threats for defending his community's land rights. COPINH leader Tomás García was shot dead by a military officer in a protest in 2013.
