Resumen

In the last ten years, the loss of forest in the Yagua communities of the Atacuari River Basin (ARB), Loreto, Peru, has had to the shifting crop (including coca) as the main causes. In this context, the impact on ecosystems by the antropic activities is unknown. The objective was to evaluate the impact on ecosystems due to legal or illegal crops in the ARB. A vegetation cover scenario was generated to 2026 and the impact of the ecosystems was spatially analyzed using the habitat quality (HQ) and spatial autocorrelation indices. By 2026, the loss of the forest would be 4935,80 ha (4,19 % of the total area, 89,55 % of the total change and 4,42 % of the forest in 2019), the quality habitat very high would change to high and moderate, and it would form patterns of cold spots in crop and pasture mosaics category with a significance (p<0,05). The future impact on the ecosystems will increase and will be negative due to a decrease in the quality of the habitat and an increase in legal and illegal crops, also impacting the structures, knowledge, practices and traditional values of resource use in the communities of the ARB.
