Demographic carrying capacity model: A tool for decision-making in Rapa Nui

Abstract

The increase of population in Rapa Nui (Easter Island) has fueled concerns within the community, given the uncertainty of its impacts. These concerns have driven a socio-political process that triggered the enactment of Law 21,070, which regulates the access and permanence of visitors in the territory as a way to cushion the pressure on different environmental, social, and infrastructure components that affect the local quality of life. However, for its application, this law requires technical foundations that allow restrictions to be applied and, therefore, knowledge about the demographic capacity of the territory is also needed. To this end, a dynamic model was built, which consists of different variables that are sensitive to population growth and also can be projected into the future, thus delivering timely information for decision-making. This paper describes the socio-political context for the creation of this instrument, as well as its elaboration process and main results.
