Campesinos in Cajamarca, Peru, continue to organize round-the-clock vigilance at the proposed site of Yanacocha company's Conga gold mine, in response to reports of construction work at the concession bloc despite official assurances that the project is suspended. Organized in rondas (self-defense patrols), the campesinos are monitoring activities at the high-altitude lakes that would have to be destroyed for the project to proceed. Idelso Hernández of the Cajamarca Unitary Struggle Front said Oct. 12, "Now there are 1,200 people mobilized to protect the lakes. The comuneros have decided to maintain a permanent presence in the zone to block any effort by Yanacocha to transfer workers or equipment there." Some 600 National Police troops have also been deployed to the site.

In an open letter Sept. 20, Human Rights Watch urged Peru's President Ollanta Humala to take steps to prevent the unlawful killing of protesters, noting growing incidents of deadly force. Local media report that at least 19 have died in protests over mineral projects since Humala took office last year. On the same day HRW issued the letter, National Police killed a protester at Barrick Gold's Pierina mine in Áncash region. The confrontation came as residents from Mareniyoc and other local villages pushed their way onto the company's property, prompting police guarding the entrance to open fire. Barrick temporarily suspend production at the mine following the clash, in which four campesinos were also injured.

On Sept. 11, a judge revoked 10 arrest warrants that had been issued against community leaders in the Guatemalan municipality of Barillas, Huehuetenango, for alleged crimes against the Spanish firm Hidro Santa Cruz, which plans to build a dam on a river outside the village. A civil court in Santa Eulalia found the warrants were issued in violation of proper procedures. The 10 were accused by the company of property destruction, kidnapping and terrorism, among other charges, after riots broke out following the murder of a community leader, Andres Fransisco Miguel, who had been an outspoken opponent of the plans to dam the Río Q'am B'alam (also rendered Canbalam). Nine community members still remain detained in Guatemala City's central prison. Saturnino Figuero of the Assembly of Peoples of Huehuetenango for the Defense of the Territory expressed hope that these would be released too, saying, "We are convinced that because this case has become national and international news, the actors in the justice system will begin to align their actions more closely with the law."

Despite recent statements indicating that the planned mega-scale Conga gold mine in Peru's northern Cajamarca region will be suspended, Yanacocha mining company has started work on a reservoir at Laguna Chaugallón near the proposed concession area, apparently in preparation for the project—sparking a new wave of protests from local campesinos. Wilfedo Saavedra, leader of the Cajamarca Defense Front, said that the regional paro (civil strike) to oppose the project would remobilize on Sept. 21, when comuneros (communal peasants) from Bambamarca province will blockade operations at the site. "We will return to protest because the Newmont company has received permission to complete the first part of the project, which consists of construction of the reservoirs," Saavedra said, referring to the US-based Newmont Mining Company which is the majority holder in Yanacocha.

On the morning of Sept. 7, as workers arrived by bus at the giant Yanacocha mine in Peru's northern region of Cajamarca, agents of the National Police Criminal Investigation Directorate (DIRINCRI) arrived and arrested employee Jesús Elías Salcedo Becerra, 38, as suspected intellectual author of the Nov. 1, 2006 slaying of peasant ecologist Esmundo Becerra Cotrina, gunned down in a hail of 17 bullets while grazing his livestock at Yanacanchilla community, La Encañada district, Cajamarca province. National Police spokesman William Vásquez called the arrest a "preliminary detention," saying that an investigation is underway in cooperation with local offices of the Fiscalía, Peru's public prosecutor. Relatives of Becerra Cotrina arrived as Salcedo was being taken away, and fiercely beat him before being restrained by police and Yanacocha security.

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.

After nearly 10 years of struggle, Mexican campesinos fighting to protect their lands from the planned La Parota hydro-dam on the Río Papagayo won a definitive victory with the Aug. 16 signing of the "Cacahuatepec Accords" by Guerrero's Gov. Ángel Aguirre Rivero and the Council of Ejidos and Communities in Opposition to La Parota Dam (CECOP). Under  the agreement, Aguirre has committed the state not to approve La Parota dam if affected communities do not accept it, if they are not justly compensated, or it will impact the environment—effectively ending the project. Aguirre is also committed to seek an audience between CECOP and Mexican President Felipe Calderón to assure a commitment to the same principles from the federal government. La Parota dam would have flooded  17,000 hectares, impacting some 100,000 local residents.
