In the Putumayo region of the Colombian Amazon, Segundo Meneses' daily routine took him to the Chufiya river, its banks verdant and waters alive with catfish and piranha. On one morning seven years ago, he noticed a dark film lapping the shore. Where the river turned a bend, it turned to black. It was an oil slick that he says went on to sicken his young family and poison their cows and pigs.
The British law firm Leigh Day is now suing Amerisur, the oil company operating in the region, on behalf of 171 Putumayo farmers, including Meneses. That spill was not the only complication with this particular oil operation. Nearby Siona Indigenous people say they reject the oil pumping and will fight it. This region is also awash in coca production and former rebel groups dispute drug territory, sometimes disrupting the flow of oil. Then there are reports by United Nations rapporteurs and an interfaith non-profit group that say the oil company, Amerisur Resources PLC, may have worked with rebels to pressure the Siona and local farmers to cease their opposition in order to keep oil flowing.
