The management of urban waste in the Provincial Municipality of Tambopata induces the environmental deterioration of the soil, water,and biodiversity along with the proliferation of diseases. The objective was to determine the citizens’ preference in reducing, recycling,reusing, recovering (4R) and their willingness to pay (DAP) for the elimination of urban waste from the classification level. Theinformation was collected through 406 surveys of heads of households by multiple-stage random sampling, complemented by in-depthinterviews; the method of choice experiments (EE) was used to determine the preference of the public user, using thelogitandmixlogitmodel to estimate the probability of the DAP. The results indicate that 68.72% of users do not recycle any waste, but are predisposedto do so. Of these, 28.72% have a preference for RR (waste collection) with the practice of “4R” for ...

La investigación tuvo por objetivo determinar el valor económico (VE) que otorgan los habitantes de Puerto Maldonado por la mejora de la gestión de residuos sólidos. Se aplicó el método de Experimentos de elección (EE) y Valoración Contingente (VC) con formato de encuesta dicotómica a 406 jefes de familia obtenidas por muestreo aleatorio, compuesto de 52.22% mujeres y 47.78% varones, entre 26 – 35 años que representa al 42.61%, grado de estudio licenciado equivalente a 38.92%, con relación al ingreso familiar el 27.83% percibe entre S/. 1 500.00 a S/. 3000.00 mensual, respecto a segregación de residuos el 68.72% no recicla ningún residuo. Los datos se analizaron con modelo logit y mixlogit para estimar la probabilidad de la disposición a pagar (DAP), a partir de precio, ingreso familiar, educación, tamaño del hogar, edad, género, educación ambiental. En términos de P...

El Pterygoplichthys pardalis (Castelnau, 1855) (Carachama) aún no se cultiva para la explotación comercial. El volumen total comercializado en Madre de Dios proviene de la pesca en medios naturales, lo que representa un riesgo para el consumo humado, debido a la contaminación con mercurio, ocasionado por la minería aurífera aluvial artesanal. Por tanto, el presente estudio tuvo por objetivo evaluar el efecto de dieta comercial en el cultivo de P. pardalis en sistema de estanque. Se estudió cuatro tratamientos (T) de suministro de dieta, con proporciones calculados basado en la biomasa de los peces (BP) siendo: T1 (1% BP), T2 (3% BP), T3 (5% BP) y T4 (7% BP). Se sembraron 2640 unidades de P. pardalis en tres estanques. Los peces presentaron inicialmente en promedio un peso de 55,2 g y una longitud de 13,1 cm. Al finalizar los 60 días de crianza se registró una supervivencia del 10...
