A Brazilian federal judge on Aug. 23 ruled that permits for more than 120 proposed hydro-electric dams in the Upper Paraguay River Basin cannot be issued without first conducting environmental impact assessments, dealing a blow to a major thrust of development planned for the states of Mato Grosso and Mato Grosso do Sul. The ruling comes in response to a request from state and federal prosecutors in Mato Grosso do Sul, who petitioned the 1st Federal Court in Coxim for an injunction suspending construction of 126 new dams in the Pantanal, a vast region of wetlands in the basin. The ruling also impacts 20 already operating hydro plants, which will be able to continue running under their current licenses, but must submit to an impact study before seeking license renewals. Utilities must seek approval for the studies from the Brazilian Institute for the Environment and Natural Resources (IBAMA) as well as state authorities before the projects can move ahead.

A panel of UN human rights experts on Aug. 21 urged Chile to make sure that people who have been convicted of enforced disappearances all serve their sentences. The UN Working Group on Enforced or Involuntary Disappearances (WGEID) stated that while Chile has made great strides since it transitioned to democracy, many challenges remain. While the WGEID praised Chile for combating human rights violations in recent years, it stated that Chile needs to do more to ensure that justice is served:

Chilean high school students occupied two important schools in Santiago on Aug. 13, after taking over at least eight public high schools the week before in a continuation of protests for educational reform that started more than a year ago. The students occupied the Barros Arana National Boarding School (INBA) and the prestigious High School of Implementation. They also tried to take over the José Miguel Carrera National Institute but gave up when police contingents arrived. Agents arrested 14 youths allegedly involved in the actions, which were supported by hundreds of students.

Students had occupied several of the public high schools in Santiago by the morning of Aug. 10 in the latest protest against the privatization of Chile's educational system that started under the 1973-1990 dictatorship of Gen. Augusto Pinochet. Chilean high school and university students launched a militant movement in the spring of 2011 to demand free, high-quality public education; current demands also include rejection of the so-called "Hinzpeter Law," legislation proposed by rightwing president Sebastián Piñera last year to impose severe penalties on people who occupy schools or public or private buildings, or who cause damage in protests. Student actions included some 40 marches in 2011 and five so far this year.

Brazil on Aug. 8 announced the mobilization of nearly 9,000 military troops to its borders with four neighboring countries as part of an operation aimed at interrupting narco-trafficking networks. Army, navy and air force personnel are being deployed along the frontiers with Argentina, Paraguay, Bolivia and Uruguay, the Defense Ministry said in announcing the mobilization, which has been carried out as an annual exercise since 2007. "One of our objectives is to control the airspace which is being used for illegal activities such as the drug trade and other contraband," said Brigade Commander Jose Geraldo Ferreira. The operation, code-named Agata 5, will last 30 days and bring F-5 fighter jets to the skies above the border zones. It will also involve sending troops to Brazil's Amazon region to crack down on outlaw gold mining. (BrazzilMag, Bernama, UPI, AP, Aug. 8)

A group of 23 contract workers occupied the San Ambrosio Church in Vallenar, capital of the northern Chilean province of Huasco, on the morning of Aug. 4 to protest labor conditions at Pascua Lama, an open-pit gold, silver and copper mine being built in the Andes at the border between Argentina and Chile. Eight of the protesters took over the bell tower, where they shouted and banged on the metal structure to draw attention to their complaints against the mine's operator, the Toronto-based Barrick Gold Corporation.

A federal court in Brazil on Aug. 1 ordered Chevron and drilling company Transocean to suspend all oil drilling in the country within 30 days in the wake of two oil spills off the coast of Rio de Janeiro. A judge for Brazil's Regional Federal Court of the Second Region ruled that each company must pay 500 million reals, or $244 million, for every day that they do not comply with the suspension. In November, a Chevron appraisal well leaked 155,000 gallons of oil. In March, oil started leaking again from the well and Chevron suspended production in that oil field. In its ruling, the court rationalized that two oil spills in the span of four months demonstrated that Chevron and Transocean cannot operate the wells safely. Chevron plans to appeal the ruling, saying that it complied with all applicable laws and industry standards. 

Jamie Sokalsky, CEO of the Toronto-based Barrick Gold Corporation, announced on July 26 that major problems were delaying the opening of the company’s controversial Pascua Lama gold and silver mine, located in the Andes on both sides of the border between Argentina and Chile. The project will cost as much as $8 billion, he said, 60% more than previously projected, and gold won't be produced until mid-2014, a year later than expected. Barrick's stocks dropped quickly, although they recovered somewhat, ending the day down by about 4.32%. The mining giant’s shares have fallen by almost 33% since the beginning of the year.
