More than 3,000 members of indigenous and Afro-descendant communities have been displaced over the past week as Litoral de San Juan municipality of Colombia's Chocó department has been convulsed by a three-way conflict between government troops, ELN guerillas and remnant right-wing paramilitary forces. The majority of the displaced have taken refuge in the municipal center as fighting engulfs outlying hamlets, according to the UN High Commissioner for Refugees. Some of the displaced have started to voluntarily return, although the threat of violence remains. (El Espectador, April 22)

Electoral authorities in Sudan say the results are in from the April 11-13 referendum on the administrative boundaries of strife-torn Darfur, with 97% voting to maintain its current five-state status. But the vote was boycotted by the civil and armed opposition alike in Darfur. Students at El-Fasher University in North Darfur protested the vote, and similar rallies were held in at least three IDP camps in Central Darfur. The US State Department issued a statement saying the referendum was unlikely to be fair, asserting that "insecurity in Darfur and inadequate registration of Darfuris residing in internally displaced persons (IDPs) camps prohibit sufficient participation." The statement drew diplomatic protests from Sudan's regime, which supported maintaining the five-state status quo and posed the referendum as fulfilling terms of the 2011 Darfur peace agreement signed with some rebel groups, the Doha Document for Peace in Darfur.  But rebel factions that did not sign on remain in arms, and even as the vote was prepared violence has again escalated in Darfur.

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.

A force of Ethiopian troops crossed into South Sudan on April 20 to launch a joint offensive with the Juba government against ethnic Murle militia fighters who staged a bloody raid into Ethiopia's Gambela region a week earlier. The Murle militiamen attacked several villages and massacred over 200 civilians of the Nuer ethnicity in the raid, and abducted some 100 children as well as stealing some 2,000 cattle. News reports initially described the incursion as a cattle raid, but the militiamen were said to be armed with AK-47s and wearing uniforms. Hundreds of thousands of South Sudanese, mainly Nuer, have fled to Gambela to escape armed conflict. The raid has heightened fears of the South Sudan war spilling into Ethiopia.

Thousands marched in Cairo on April 15 to protest President Abdel Fattah al-Sisi's decision to turn two disputed islands over to Saudi Arabia. Crowds chanted slogans such as "Sisi – Mubarak," "We don't want you, leave," and "The people want the downfall of the regime"—the iconic slogan of the Arab Revolution. Security forces responded with tear-gas; at least 25 were detained and are being held on charges of violating Egypt's controversial anti-protest law. More protests are planned for this weekend, and on April 22 security forces carried out pre-emptive arrests of noted activists in an apparent effort to head them off. Cafes in downtown Cairo were raided and activists seized from their homes, prisoners' rights group Freedom for the Brave said in a statement on Facebook. Pre-emptive arrests were also reported in Alexandria and in Gharbeyyia governorate.

Tizi Ouzou, principal city in Algeria's restive Kabylia region, saw two mass mobilizations April 20 to commemorate the 1980 "Berber Spring" uprising. One, organized by the Rally for Culture and Democracy (RDC), pressed demands for official recognition of the Amazigh language in Algeria's constitution. But the second, led by the Kabylia Self-Determination Movement (MAK), called for the region's actual independence from Algeria. Each drew thousands, and several arrests were reported. Amazigh was recognized as a "national language" in a 2002 constitutional reform, and second reform earlier this year upgraded it to "official" status, meaning it can be used in government functions. However, Berber activists say that even the new reform maintains Amazigh in a subsidiary position to Arabic.

For a third year running, Amnesty International's annual report on the death penalty notes an alarming surge in the number of executions worldwide—now reaching the highest total since 1989. At least 1,634 people were executed in 2015, a rise of more than 50% over the previous year. Iran, Pakistan and Saudi Arabia were leading the field, responsible for 89% of the executions. Iran executed at least 977 in 2015—the vast majority for drug-related crimes—compared with 743 in 2014. Those put to death included at least four who were under 18 at the time of the crime—which Amnesty called a violation of international law. Pakistan continued what Amnesty called as a "state-sanctioned killing spree" that began when a moratorium on civilian executions was lifted in December 2014. Pakistan sent at least 326 to the gallows last year, the highest annual total Amnesty has recorded for that country. Executions in Saudi Arabia rose by 76%, with at least 158 people put to death, Amnesty said. Most were beheaded, with the bodies often displayed in public.

Maxima Acuña, a campesina grandmother from Peru's northern Cajamarca region, has been named the 2016 Goldman Environmental Prize winner for South and Central America for her struggle to defend her family's lands from Newmont Mining. "A subsistence farmer in Peru's northern highlands, Maxima Acuña stood up for her right to peacefully live off her own land, a property sought by Newmont and Buenaventura Mining to develop the Conga gold and copper mine," the prize's official webpage indicates. At the award ceremony in San Francisco April 18, Acuña denied being a social leader, saying: "I only want them to leave me in peace on my land and that they do not contaminate my water." Considered the "Green Nobel," the Goldman Prize honors grassroots activists for significant achievements in protecting the environment worldwide.
