Valoración económica ambiental de la gestión integral de residuos sólidos urbanos en Bambamarca, Perú

Ineffective management of municipal solid waste (MSW) in Peru has led to increased environmental pollution and low citizen participation. To quantify the perceived value of environmental improvements and mitigate this problem, this study aimed to determine the Environmental Economic Value (EEV) of Integrated MSW Management in Bambamarca, Peru. The research used a quantitative, basic, descriptive approach with a non-experimental design. The Contingent Valuation Method (CVM) and a Logit econometric model were applied to a simple probability sample of 361 heads of household (population: 5,988). The data were obtained through questionnaire surveys and analyzed using SPSS 26.0 and Stata 17.0 software. The results indicate that 65.9% of households are willing to make a monthly payment for the implementation of an improved management system. The average willingness to pay (WTP) was estimated at S/ 5.34 per month, with the most frequent contribution range (S/ 5 to S/ 10) accepted by 45.2 % of respondents. It is concluded that the annual Environmental Economic Value (EEV) of integrated MSW management amounts to S/ 252,766.08, confirming the economic viability and potential for partial self-financing of the service in the locality.
