| description | Abstract Rooftop Rainwater Harvesting (RRWH) offers a viable solution to the pressing issue of saline groundwater in regions like Ainavolu, a village in Andhra Pradesh, India. This study examines the potential of RRWH systems to provide a sustainable alternative water source in rural settings faced with water scarcity due to saline groundwater. Firstly, in view of the limitation in terms of spatial resolution associated with satellite imagery, a UAV-based survey is conducted to create a high-resolution orthomosaic of the study region, enabling precise delineation and classification of rooftop materials to estimate harvestable rainwater. Findings of this study suggest that RRWH could significantly alleviate water shortages by potentially collecting approximately 20.16 million litres of rainwater annually. However, despite this substantial capacity, the adoption of RRWH remains limited due to financial, technical, behavioural, and institutional factors. Through comprehensive fieldwork, including focus group discussions and one-on-one interactions, we identified 17 critical factors hindering RRWH adoption. Based on these insights, we propose a tailored roadmap to promote RRWH implementation, incorporating strategies such as partnerships with local vendors, specialized training programs, subsidies, and targeted awareness campaigns. This study not only underscores the practicality of RRWH in offsetting the challenges posed by unsuitable groundwater but also provides a scalable model for enhancing water security through community-based initiatives and technological integration. Since the scenario of water scarcity and responses of residents change with the cultural and economic characteristics, it is suggested to update the factors while adopting the proposed framework. |
