Illegal mining fuels new conflicts in Peru, threatens ancient dig site
July 6 (UPI) -- Illegal mining is giving rise to a new type of social conflict in Peru, pitting rural communities against networks operating outside the law, while threatening water sources, ecosystems.
It's also threatening one of the world's most important archaeological treasures -- the Nazca Lines, which are are among the world's most important collections of geoglyphs that include figures of animals, plants and geometric shapes created about 2,000 years ago,.
This warning appears in a social conflicts report by Peru's Ombudsman's Office, which identified six active conflicts related to illegal mining in different regions of the country.
The offcie warned, though, that the scale of the problem could be greater because many cases are never included in official records.
Unlike traditional mining disputes, which historically pitted communities against formal mining companies, the new conflicts involve associations of illegal miners, mineral processing plant operators, transporters and other networks linked to illicit activities, making government intervention more difficult, Rumbo Minero reported.
According to the Ombudsman's Office, because these organizations operate outside the law, there is often no formal representative with whom authorities can negotiate or demand accountability.
That situation limits institutional dialogue mechanisms and increases the risk of violence, particularly because of the alleged involvement of criminal organizations, Visión Informa reported.
The phenomenon has already spread nationwide. In Huanta, in the Ayacucho region, farmers and social organizations are demanding an end to small-scale mining activities to protect the headwaters and the Razuhuillca lagoon system, a source of drinking water and agricultural production, according to the Ombudsman's report.
In Arequipa, communities say illegal mining is affecting their land and water resources.
In the province of Pataz, in the La Libertad region, security problems and pollution linked to illegal mineral extraction persist.
Farther north, in the Peruvian Amazon, Indigenous communities in Loreto are calling for greater government intervention to halt the expansion of these operations, Revelación Perú reported.
The report also includes protests by informal miners demanding an extension of the Comprehensive Mining Formalization Registry, known as REINFO, and a new law governing small-scale and artisanal mining.
In addition, the Ombudsman's Office warned that some conflicts remain outside official records, including the case of the Yolita mineral processing plant in the Cusco region, where local residents reported environmental contamination and threats.
The expansion of illegal mining is also threatening Peru's cultural heritage.
The Nazca Lines, situated in the Ica Desert and designated a UNESCO World Heritage Site in 1994. German mathematician Maria Reiche studied the site for decades and demonstrated the figures are part of a complex ceremonial landscape associated with the Nazca culture and the ceremonial center of Cahuachi.
Today, that legacy faces growing pressure. More than 130 illegal mineral processing plants operate among populated areas, farmland and buffer zones surrounding the archaeological complex, while the accumulation of garbage, urban expansion and looting of archaeological remains are further degrading the site, RT en Español reported.
Residents have also reported the presence of illegal dumping sites and dead animals on the plains where the geoglyphs are found.
As illegal mining expands, the Peruvian government said it has intensified operations against these plants.
During an operation in the district of Inambari, in the Amazon region of Madre de Dios, members of the Army, the National Police and the Specialized Environmental Prosecutor's Office destroyed 17 clandestine camps, 13 rafts, five pits, four hoppers and various pieces of equipment used for illegal gold mining, Infobae Perú reported over the weekend, citing the Ministry of Defense.
The destroyed assets were valued at more than $1.6 million. Between January and May, authorities destroyed machinery and equipment used by organizations engaged in illegal mining valued at more than $337 million, according to the Ministry of Defense, Infobae Perú said.
For the Ombudsman's Office, the expansion of these conflicts shows that illegal mining is no longer solely an environmental or economic problem but has become a governance challenge that threatens communities, natural resources and part of Peru's most important cultural heritage.
