AI Article Synopsis

  • Rainwater harvesting is gaining traction as an important method for addressing water scarcity and ensuring food security, despite being an ancient practice.
  • The article focuses on India to examine how agricultural rainwater harvesting ponds impact social, economic, and environmental aspects amidst climate and population challenges.
  • It advocates for a comprehensive approach that considers both water availability and social wellbeing to evaluate the sustainability of these traditional systems.

Article Abstract

Rainwater harvesting, a "soft path" approach toward water management, is increasingly recognized as a key strategy toward ensuring food security and alleviating problems of water scarcity. Interestingly this "modern" approach has been in use for millennia in numerous older civilizations. This article uses India as a case study to explore the social, economic, and environmental dimensions of agricultural rainwater harvesting ponds, and evaluates the viability of these centuries-old systems under current climate and population pressures. A holistic watershed-scale approach that accounts for trade-offs in water availability and socioeconomic wellbeing is recommended for assessing the sustainability of these systems.

A new approach on design and verification of integrated sustainable urban drainage systems for stormwater management in urban areas.

J Environ Manage

January 2025

Politecnico di Milano, Department of Civil and Environmental Engineering, Italy. Electronic address:

Stormwater runoff control is often a concern due to urbanization and extreme rainfall events. Sustainable urban drainage systems can support traditional hydraulic networks in rainwater management by providing local runoff disposal and reuse of collected stormwater. The objective of the study is based on an innovative analytical-probabilistic approach for evaluating the functioning of rainwater tanks in stormwater management with the potential for using collected water for non-potable purposes.

School of Engineering, Design and Built Environment, Western Sydney University, Locked Bag 1797, Penrith, NSW, 2751, Australia.

Rainwater harvesting (RWH) for drinking water production has been a potential solution to mitigate water scarcity in rural areas. There was limited research focusing on the quality of treated rainwater. This study developed and tested the quality of a drinking water filtration system (DWFS) for treating harvested rainwater to support rural communities.

Enhancing rainwater harvesting efficiency in karst terrains: The role of road intercepted soil-epikarst lateral flow.

J Environ Manage

January 2025

Key Laboratory of Agro-ecological Processes in Subtropical Region, Institute of Subtropical Agriculture, Chinese Academy of Sciences, Changsha 410125, China; Guangxi Key Laboratory of Karst Ecological Processes and Services, Huanjiang Observation and Research Station of Karst Ecosystems, Chinese Academy of Sciences, Huanjiang 547100, Guangxi, China. Electronic address:

In karst landscapes, where sustainable water management is increasingly challenged by drought-induced water scarcity, the adoption of road-based rainwater harvesting (RBWH) systems has emerged as a promising solution for improving water accessibility. Despite the growing implementation of such systems, the effectiveness of many RBWH projects in karst terrains remains suboptimal due to an inadequate understanding of runoff generation mechanisms associated with hilly road networks. This study focuses on quantifying the contributions of intercepted surface runoff (SR) and soil-epikarst lateral flow (SEF) from a newly exposed road-cut slope in a dolomite hillslope, with data collected across 156 rainfall events from May 2019 to May 2022.

Purification of harvested rainwater using gravity-driven ceramic membrane: A visualization study combining Micro-CT and COMSOL simulations.

J Environ Manage

January 2025

College of Soil and Water Conservation Science and Engineering (Institute of Soil and Water Conservation), Northwest A&F University, Yangling, Shaanxi, 712100, China; Institute of Soil and Water Conservation, Chinese Academy of Sciences and Ministry of Water Resources, Yangling, Shaanxi, 712100, China; Institute of Water-saving Agriculture in Arid Areas of China, Northwest A&F University, Yangling, Shaanxi, 712100, China.

Rainwater harvesting is a viable solution for providing clean water in regions where conventional water sources are scarce or contaminated. However, the harvested rainwater often contains microorganisms, suspended particles, and other impurities that must be removed before consumption. Gravity-driven ceramic membranes (GDCMs) are an efficient choice for purifying harvested rainwater due to their energy-saving properties.

Climate change adaptation in intensifying urban environments benefit from green stormwater infrastructure (GSI) investments on private residential yards. Nevertheless, planners are challenged to devise policy tools to mesh such a decentralized GSI approach with current land-use and social systems. Prior research has addressed the multi-scalar socio-economic barriers hindering household uptake, including technical and governance considerations.
