Integrating circular economy strategies into sustainable water management: Regression evidence from the Chinchaycocha Lagoon, Peru

This study analyzes the relationship between circular economy strategies and sustainable water management in the Chinchaycocha lagoon, located in the central highlands of Peru, a basin seriously affected by industrial, mining, and agricultural activities. A quantitative, correlational, and predictive approach is adopted through the application of a structured questionnaire to a sample of 50 local stakeholders involved in water management. The analysis is performed using a multiple linear regression model with ordinary least squares (OLS) estimation, complemented by tests for heteroskedasticity, autocorrelation, normality, and functional specification. The findings indicate that the environmental impact and conservation dimension exert a positive and statistically significant influence on both water use efficiency (α_(EWU,1) = 0.491; p < 0.05) and compliance with environmental regulations (α_(CER,1) = 0.567; p < 0.001). Additionally, perceived community benefits significantly influence regulatory compliance (α_(CER,3) = 0.502; p < 0.05), while financial sustainability does not exhibit a statistically significant association with the dependent variables. The study concludes that integrating environmental and community-based strategies within a circular economy framework is essential for enhancing water governance. These findings contribute valuable empirical evidence to inform the development of resilient and context-sensitive public policies for high Andean ecosystems.
