In this study, we developed a logistic regression modeling approach to analyze the relationship between utility-scale solar power plant (SPP) locations and flood hazards. Based on the standardized coefficients of the model, we compared this relationship with the relationship between SPP presence/absence and other typical spatial determinants like...

In South Asia, a region facing rapid economic growth, immense population pressure, and high climate vulnerability, the circular economy (CE) has become a critical imperative for sustainable development.
