A prominent geoscientist in Argentina is facing criminal charges over accusations that he manipulated a government survey of glaciers at the behest of mining interests.

On 27 November, a federal judge in Buenos Aires charged Ricardo Villalba, the former director of the Argentinian Institute of Snow, Ice and Environmental Research (IANIGLA) in Mendoza, with abusing his authority and violating his duty as a civil servant. Villalba appealed against his indictment on 4 December — but if he loses, the case will go to trial. In the meantime, the court has ordered Villalba to stay in the country, and has authorized the seizure of his assets up to 5 million pesos (US$289,000).

The case hinges on the definition of a glacier as viewed from space. When Villalba began the government survey in 2011, he determined that it would include glaciers of 1 hectare or larger — following international norms for satellite analyses. But environmental activists in Argentina’s San Juan province argue that he excluded some smaller glaciers to prevent tougher regulation of adjacent mines operated by the Barrick Gold Corporation of Toronto, Canada. Villalba’s scientific colleagues in Argentina and abroad say the charges against him are baseless and political.

International support

“It’s surreal and kind of ridiculous,” says Bruce Raup, a glaciologist at the National Snow and Ice Data Center in Boulder, Colorado, who co-authored a letter of support for Villalba.
