This review examines state-of-the-art practices in water harvesting and groundwater recharge, emphasizing their crucial role in sustainable water resource management. Groundwater, a crucial resource for drinking and agricultural water, is facing depletion due to the combined effects of urbanization, climate change, and unregulated extraction. This paper provides a comprehensive overview of contemporary knowledge on water harvesting and recharge, using a systematic four-step methodology to identify and analyze relevant studies from databases like Google Scholar, Scopus, and ScienceDirect. It categorizes water harvesting techniques, such as rainwater, flood water, and groundwater harvesting, and evaluates their effectiveness in enhancing recharge. Both natural and artificial recharge methods are explored, highlighting their role in improving groundwater levels and water quality. This study also reviews recharge estimation techniques and their applicability across hydrogeological contexts. This paper promotes a balanced approach to address issues of water scarcity by integrating water harvesting into groundwater management strategies. This integration aims to build resilience against climate change-driven environmental damage. Recommendations are provided to enhance the sustainability of these practices, with a particular focus on arid and semi-arid regions where water demand is rising. Overall, this study underscores the significance of water harvesting and recharge in promoting long-term resource sustainability.
