Abstract

This study proposes indicators based on urban, demographic, and hydrological parameters to assess the effectiveness of low-impact development (LID) techniques, such as rooftop rainwater harvesting, aimed at reducing water scarcity in a residential area vulnerable to water shortages in a semi-arid city in the Global South. In the study area, the necessary water demand is identified according to land use requirements established by national and local regulations, and an urban configuration pinpoints spaces suitable for rainwater harvesting for self-consumption. Additionally, hydrological design conditions are defined to evaluate the potential volumes of recoverable water. Accordingly, indicators of infiltrated water, availabel water for consumption, runoff water, and sufficient water are established, enabling the proposal of strategies to mitigate water scarcity and enhance water management.
