Water harvesting is the process of collecting and storing rainwater for later use. This practice helps conserve water resources, reduce runoff and erosion, and provide a supplemental water source for agricultural, residential, and commercial purposes. Water harvesting techniques can range from simple rain barrels to more complex systems that collect and store large amounts of rainwater for irrigation or other uses. This research area explores the benefits, challenges, and best practices of water harvesting in various contexts, including urban and rural settings.
