El objetivo de la investigación fue determinar la disposición a pagar (DAP) de la población por la implementación de estrategias de conservación de bosques que regulan el recurso hídrico en el distrito de Chontabamba mediante el método de valoración contingente. Para la recolección de datos se aplicó una encuesta definitiva a 234 usuarios de agua (conexiones domiciliarias) en el mes de julio del 2019 a pobladores que corresponden a sectores de Nueva Berna, San José, San Carlos, y Santo Domingo que captan agua para uso y consumo de la Zona de Interés hídrica (ZIH) Dos de Mayo del distrito de Chontabamba. La encuesta tuvo formato de respuesta dicotómica (variable dependiente binaria) y de respuesta múltiple (variable independiente continua categórica y variable discreta categórica ordenada). Se aplicó la regresión no lineal utilizando el modelo logit de elección binaria...

We present the characterization of the aquatic environment, riparian ecosystem and macroinvertebrate communities in 7 basins of the west slope of the Yanachaga Chemillén National Park (PNYCh). The CERA protocol, including the Andean Biotic Index (ABI), the Fluvial Habitat Index (IHF), the Andean Creek Index (Qbr-And) were estimated and the combination of these 3 indexes allowed to calculate the Ecological Status Index of Andean Rivers (ECOSTRIAND) at each sampling point. Additionally the FBI and BMWP-Col indexes were calculated. Sampling was carried out in the 7 basins, between 1800 and 2500 meters of altitude, including the upper basins inside the PNYCh, in the middle and lower basins, both in the buffer zone of the park. We found 179 taxa, 66 families and 14 orders in all basins evaluated. Within the PNYCh, the values of IHF and Qbr-And were optimal, but to go down basins, the indexes...
