Impacts of anthropic activities on the nevado Huaytapallana
Abstract
Objectives: To explain the influence of the anthropic activities on the variation of the snow accumulation layers on glaciers in the south-west drainage basin of nevado Huaytapallana of the central Andes of Peru in the hydrological cycle 2011-2012. Methods: We used the general method hypothetical - deductive to guide the quantitative research, the Thornthwaite method to perform the hydrological analysis and the climate classification of the area, in addition the mass balance like the method for estimating the bulk and volley of accumulated snow by beacons. Results: We found that anthropic activities of experiential tourism are one of the main activities that affect the glacier with 60% of impact. Reforestation activities constitute 20% of impact and 10% the activity grazing. Also the impact of anthropic activities at low altitudes in the glacier are negative, while at latitude above 5 000 msl are recorded minor negative impact. Similarly we found a direct relationship (coefficient r=0,97) between the impact at low altitudes of glacier masses. Conclusions: The experiential tourism activity that takes place in various sectors of the nevado Huaytapallana, is one of the main anthropic activities that is generating negative impacts in the glacial system becouse it accelerate the mass loss of accumulated snow during a hydrological cycle.References
