Abstract

The Cusco-Quillabamba highway (Peru) is one of the most important roads in the Cusco region. The study was carried out on the section Abra Malaga-Alfamayo, 29 km long that crosses natural life zones rich in biodiversity and a geology with fractures and constitutes a critical and vulnerable zone due to inadequate management and inappropriate implementation of the Environmental Management Plan in the operation stage, generating social, environmental and economic problems. The research was developed using the exploratory and descriptive method and methodologies for the measurement in the field of indicators (cant, slopes, EIA); The environmental impacts were evaluated in the operation stage and it is found that 100% of the cans are not bound by national regulations; the slopes in the section are higher than 70 ° so they generate landslides and rockslides and sediments; the methods applied to measure environmental impacts indicate negative impacts on biodiversity, air, water and soil quality. Knowing the negative impacts and that they are reversible, it proposes the implementation of corrective measures to the environmental impacts in the section, such as revegetation with native species, construction of passes for fauna, which allow the conservation of the biodiversity in the area and a normal road traffic.
