El presente trabajo de investigación, “Impacto de la cosecha de agua de lluvias, en la comunidad campesina de Cuyuni, distrito de Ccatcca, provincia de Quispicanchi” se realizó en la comunidad campesina de Cuyuni del distrito de Ccatcca, provincia de Quispicanchi, con el objetivo de evaluar y describir los impactos tecnológicos, económicos y socio culturales generados por la cosecha de agua de lluvias. La investigación es de tipo descriptivo de corte transversal, que para lograr identificar los resultados de los cambios, tecnológicos, económicos y socio cultural, se ha acudido a encuestas estructuradas, tanto individuales y grupales para autoridades y ex – autoridades, cuyos resultados son: En los cambios tecnológicos, en el área agrícola se ha identificado que, del uso del tirapié (chaki taklla) y la fuerza humana en el barbecho, los productores han optado por el uso de...

Floristic composition and rangeland condition of the Phynaya Peasant Community (located North of Pitumarca district and EastNorth of Canchis Province, Cusco region) were evaluated to estimate stocking rate under climate change scenario. Floristic composition, vegetation cover, and plant vigor were evaluated on 79 step-transects of 200 m in six rangeland sectors. Preliminary results reveal that there are 60 species, grouped in 13 families, where the dominant families were Poaceae (46.67%), Asteraceas (15%) and seudograsses (13.3%), of which, 45% were palatable for alpacas. Of the total grazing areas, alpacas´ areas represent 70.4%, llamas 15.4%, cattle 3.5%, sheep 4.5% y vicunas 6.3%. Actual stocking was 1 alpaca unit per hectare while stocking rate average estimated was fair with supportability of 0.78 UAl/ha; thus, rangelands are considered on degradation process

The study was carried out in the river wetlands of San Pedro and San Pablo adjacent to the Vilcanota River in the province of Canchis, Cusco, in southern Peru. The objective was to estimate the production of aerial biomass and the animal carrying capacity of these wetlands from the analysis of samples acquired in the field and NDVI orthophotographs. The images were acquired with a Parrot sequoia multispectral camera, transported by a Matrice 100dji Drone and processed in Pix4D and ArcGIS 10.6 software. The study identified 5 types of land use: wetland, agriculture, urbanization, salt and water. The estimated biomass production with field data was 2,359.46 kg/ha and 2,885.78 kg/ha, while the estimate with NDVI orthophotographs was 2,321.71 kg/ha and 3,048.72 Kg/ha for the wetlands of San Pablo and San Pedro respectively. The estimated animal load capacity from field data was 0.48 U.V/ha/y...

Remote sensing with large-scale satellite images for precision studies in grasslands has spatial and spectral resolution limitations. Against this, using spectral signs and vegetation indices obtained with microsensors transported by unmanned aerial vehicles (UAV) constitutes a more accurate alternative for biomass estimation. In the fieldwork, images were acquired with microsensors, and fixed transects of 100 m were used where vegetation samples were collected. The photographs acquired with the UAV were processed in Pix 4D, Arc Gis, and algorithms elaborated in R programming language. The biomass estimation was carried out with Multiple Linear Regression, Vector Support Machine, and Random (Forest Random) models. The Random model showed a Kappa coefficient of 0.94 in the training set and 0.901 in the test set (R2 = 0.482). The Random Forest model predicted 3 g/pixel of MV for Puna grass...
