PLAZA-ORTEGA, Vianny; VALENCIA-ROJAS, Mónica Patricia  y  FIGUEROA-CASAS, Apolinar. RELATIVE INTEGRATED ANTHROPIZATION INDEX (INRA) APPLICATION IN A HIGH MOUNTAIN ECOSYSTEM. Luna Azul [online]. 2017, n.44, pp.80-93. ISSN 1909-2474.  http://dx.doi.org/10.17151/luaz.2017.44.6.

Given the high mountain ecosystems are no strangers to the establishment of anthropic activities, the objective of the research was to estimate the level of anthropization in a wasteland lagoon system located in the Puracé National and Natural Park, by adapting the Relative Integrated Anthropization Index (INRA). To this end, a study window of 6x5Km2 within the lagoon system was selected through GIS tools, which was divided in Units of Analysis (UA, from the Spanish acronym) of 0.5Km2, each UA contains Subunits of Analysis (SUA, from the Spanish acronym) of 0.1Km2 where different land cover (natural and anthropic) found in the ecosystem were polygonized and assigned a value of 0 to 1, according to the index scale. The results obtained with the application of RIAI, emphasized that the most frequent assessment category was the Cover without human intervention called A (69.51%), followed by the category Forests without human intervention called B (17.29%). The category related to free grazing Zones was the lowest (0.97%) while the Forests categories with anthropic intervention (Burning and grazing) and Infrastructure presented values of 4.17% and 8.02%, respectively. These results suggest that the lagoon system has a low level of anthropization which evidences that anthropic activities in the area do not generate a strong impact on the ecosystem due to their low frequency and magnitude, thus making possible to keep stable the ecosystem functions and dynamics.
