Agreement reached between Argentina and Paraguay over closure of Pilcomayo canal

(5 November 2010)

An irrigation canal built by Argentina to divert water from the Pilcomayo River has begun to be closed by authorities. The Pilcomayo forms approximately 40 percent (around 764 km) of the land boundary between Argentina and Paraguay. Neighbouring Paraguay voiced complaints over the unilaterally built canal in late September 2010, which stretches some 800 m, and even threatened legal action. Paraguay claims that they were not informed about the canal project, breaching existing agreements with Argentina regarding the boundary river, so a bilateral taskforce was formed to investigate the issue in October 2010. The two states negotiated a deal to close the canal in October, and works are expected to be completed by 7 November 2010.
