In 2004, the United States and Chile signed a free trade agreement, whose environmental cooperation chapter is reviewed annually to define a work plan on related matters between both countires. In the context of the IV Planning Meeting of the agreement, embassy officials invited representatives of the Cape Horn consortium to participate in elaborating this document. OSARA President Christopher Anderson presented to US Assistant Secretary of State for Environment and Science Ambassador Reno Harnish and his staff the activities in the Cape Horn Biosphere Reserve that could be reinforced by this treaty, including setting goals for sustainable ecotourism, capacity building of park administrators and creating volunteer programs to improve infrastructure. Working together with staff from the US Embassy, the State Department and the Chilean Ministry of Foreign Affairs, OSARA will continue to promote these concepts with the goal of linking conservation and sustainable development in the extreme south via this binational agreement.
