At least 800 members of Section 65 of the National Union of Mine and Metal Workers and the Like of the Mexican Republic (SNTMMSRM, "Los Mineros") began blocking the three main entrances to the giant Buenavista del Cobre copper mine in Cananea, near the US border in the northwestern state of Sonora, on Aug. 20 to protest environmental damage caused two weeks earlier when about 40,000 cubic meters of copper sulfate acid solution spilled from the mine into the Bacanuchi and Sonora rivers. Most of the unionists lost their jobs four years ago when the mine's owner, Grupo México S.A.B. de C.V., broke a 2007-2010 strike over health and safety issues. "During the strike we made several complaints about the improper and inadequate measures Grupo México implemented for preventing overflows from the dams" for chemicals and heavy metals, Section 65 director Sergio Tolano Lizárraga told the national daily La Jornada. He said the blockade would continue until the company recognized the workers' old contract. (LJ, Aug. 22)

After the abduction of more than 500 Yazidi women and girls by ISIS fighters at Sinjar, the jihadist group has established a special office in the Quds neighborhood of Mosul city where the women are being sold, according to Evar Ibrahim, head of the Women's Committee in the Kurdistan Regional Government's parliament. Ibrahim said the girls are being sold for 30,000 dinars, or about $26. "Despite selling them, the Yazidi girls have been raped by the IS insurgents," Ibrahim added. (BasNews) An official spokesman of Patriotic Union of Kurdistan (PUK) in Khanaqen district, Hemin Mansour, charged that ISIS militants are evicting any remaining Kurdish families from Jalawla (Diyala governorate), and have demolished some houses belonging to Kurdish residents of the town. The evictions are being justified on the grounds that the Kurdish families were collaborating with the Peshmerga. The ISIS flag is also being raised over seized Kurdish homes to make them a target for air-strikes. (BasNews)

The taking of the Mosul Dam on the Tigris River from ISIS by Kurdish Peshmerga forces backed by US air power highlights the strategic nature of water in the multi-sided Iraq conflict. Even before ISIS seized the giant dam in early August, the militants were taking advantage of the country's drought, cutting off the flow of water from the dam to Baghdad through territory under their control. "ISIS is starting to use dams as weapon of war," wrote meteorologist Eric Holthaus, Slate's Future Tense blog. "So they've made [it] high on their list to take over those dams and control the water downstream." July saw battles between ISIS militants and government troops over the Haditha Dam and its hydroelectric works on the Euphrates. The fall of the complex to ISIS would have given the rebels control over Baghdad's electricity source. But the most grave danger has not passed: ongoing fighting and air-strikes in the area of the Mosul Dam could lead to the dam being breached, which would flood Mosul and other downstream cities, possibly even affecting Baghdad.

A Yazidi militia group has entered the fight against ISIS, clashing with militants near Sinjar. Khudida Kicho, a member of the Yazidi militia, said in a press conference in Erbil: "In the Kahbel area near Sinjar our fighters were able to attack IS militants and kill 24 of them. In the clashes three of our fighters were killed as well, but we will continue to fight terrorists until the end." (BasNews) Kurdish Peshmerga leaders meanwhile said their forces have seized full control of the Mosul Dam, in coordination with US air-strikes on ISIS positions in the area. (IraqiNews.com) But in Baghdad, the general command of Iraq's armed forces warned against foreign planes breaching the nation's airspace and arming "a certain Iraqi faction"—a clear reference to Western arming of the Peshmerga. "We welcome international support for Iraq in its war against terrorism," read the statement. "But Iraq's territorial sovereignty must be respected." (Rudaw, IraqiNews.com)

A survivor who managed to escape by feigning death described a general massacre at the ISIS-occupied Yazidi village of Kojo 20 kilometers south of Sinjar. The village was surrounded by ISIS fighters 12 days ago, with residents ordered to convert on pain of death. On Aug. 15, the fighters moved in, and rounded up the villagers, separating the men from the women and children. The men were lined up and machine-gunned. Up to 80 are believed to have been killed. (BasNews, AP, Reuters) ISIS forces have reportedly brought Sunni Arabs into the cleansed Yazidi town of Sinjar in response to US air-strikes on nearby Arab villages. Yazidi homes are being given to the Arab families. (BasNews) The Kurdistan Regional Government's Peshmerga forces have joined with PKK-aligned Kurdish militias to form the Sinjar Defense Units, to take back the town. (Rojava Report) The KRG's Peshmerga Ministry issued a statement naming several villages where "IS militants" suffered "heavy losses" under US bombardment. Peshmerga forces backed by US air-strikes have also opened an operation aimed at recovering the ISIS-held Mosul Dam.

Authorities on Aug. 10 imposed restrictions on the water supply to seven municipalities in northwest Mexico's Sonora state, after 40,000 cubic meters (10 million gallons) of toxic leached copper from the Buenavista del Cobre mine turned the Río Bacanuchi orange, killing fish and livestock. Among the towns cut off by order of the National Water Commission (Conagua) is the state capital, Hermosillo, home to nearly 800,000 people. The Bacanuchi is a tributary of the Río Sonora, the state's principal river. Sonora state civil defense director Carlos Arias accused mine owner Grupo México of not reporting the spill in a timely manner.

Nicaragua's Commission for the Development of the Grand Canal on July 7 approved a route for the proposed inter-oceanic canal through the Central American country. The waterway, to be built by Chinese company HKND, is slated to run from the Río Punta Gorda (South Atlantic Autonomous Region) on the Caribbean Coast to Brito (Rivas department) on the Pacific coast—a route more than three times as long as the 48-mile Panama Canal. The Commission said the canal will be operational by 2020, but questions have been raised on how the Hong Kong-based company plans to finance the project, estimated at $50 billion—nearly four times greater than Nicaragua's national economy. The canal is to be privately owned and operated. Ecologists have raised concerns about impacts on Lake Nicaragua (also known as Cocibolca), Central America's largest lake and an important fresh-water source for the country. There are fears the the water used by the canal's locks could seriously deplete the lake. The Río San Juan, which feeds the lake and forms the border with Costa Rica, would be dammed to feed the locks. Costa Rica has formally demanded the right to review environmental impact studies for the project before work begins. The Rama-Kriol indigenous people, whose territories in the Punta Gorda river basin would be impacted, are demanding to be consulted on the project. (La Prensa, Nicaragua, July 17; Tico Times, Costa Rica; July 15; Nicaragua Dispatch, Reuters, El Financiero, Mexico, July 8)

Brazilian federal judge Claudio Henrique de Pina has revoked Toronto-based Belo Sun Mining Corp.'s environmental license for the construction of the $750 million Volta Grande open-pit gold mine near the Xingu river in the northern state of Pará, the federal Public Ministry office in the state announced June 25. Upholding a suspension ordered last November, the judge ruled that Belo Sun had failed to address "negative and irreversible" impacts the mine would have on three indigenous groups in the area, the Paquiçamba, Arara da Volta Grande and Ituna/Itatá. The communities are already under threat from the construction of the Belo Monte dam, which will cut water flows by 80% to 90% when it goes into operation, according to the government's National Indigenous Foundation (FUNAI).
