Since the early 19th century, a number of Latin American countries have had active interests in the Antarctic continent. These interests began to accelerate in the early 20th century, and during the 1930s and 1940s, Argentina and Chile formalized sovereignty claims to the Antarctic Peninsula region. These claims overlapped not only with each other, but also with Great Britain’s claim to the “Falkland Islands Dependencies.” The two Latin American claims tended to be framed in the language of anti-imperialism, and for a while at least the idea of a “South American Antarctica” emerged to suggest a common front against the British Empire. Rivalry between Argentina and Chile, however, remained strong, and the alliance against imperialism never developed into a lasting agreement. In 1959, Argentina and Chile joined with ten other nations—including Great Britain, the United States, and the Soviet Union—in signing the Antarctic Treaty. This Treaty suspended sovereignty claims and created a “continent dedicated to peace and science.” Following the ratification of the Treaty in 1961, Argentina and Chile lessened their hostility to the imperial strategy of using scientific research as a justification for political claims, and came to be enthusiastic members of what some outsiders labeled an “exclusive club.” During the 1980s and early 1990s, four other Latin American nations—Brazil, Uruguay, Peru, and Ecuador—became full members of the Antarctic Treaty, attracted, in part, by the prospect of sharing in a potential minerals bonanza in the southern continent. This expected economic boom never came, however, and instead the Antarctic continent became one of the most protected environments anywhere on the planet by the terms of the 1991 Madrid Environmental Protocol.
The history of Colombian national parks started in 1948 with the establishment of a reserve for scientific research, which stood alone until the 1960s, when various state agencies created a few parks with quite different goals in mind, including preserving imposing landscapes and conserving water. This rather casual development changed after the growing international concern for the environment led to the creation of an environmental agency in 1968 and the enactment of an environmental code in 1974, which served as institutional platform for the planned expansion of a system of national parks based largely on ecological criteria.
Chronically underfunded and understaffed, the Office of National Parks has confronted its weakness by establishing parks which confer legal protection on areas whose natural attributes were deemed valuable. Such a strategy has led to confrontations with local populations living in and around parks, whose rights to resource use have been hampered. The office’s incapacity to properly enforce rules and its attempts to work with rural communities, especially indigenous groups, have to some extent mitigated such tensions. It has further sought to enlist the support of the middle classes and been forced to deal with illegal armed groups on the left and the right, as well as the national army, vying for territorial control. Although parks have not fulfilled their ideal, they have fostered the notion that the nation has a natural patrimony and have contributed decisively to its conservation.
