Water harvesting is one of the most effective measures to combat drought because it helps conserve, store and efficiently use rainwater during periods of water scarcity. Drought occurs when rainfall is inadequate for a prolonged period, resulting in reduced availability of water for drinking, agriculture, livestock and other domestic needs. Water harvesting provides a practical and sustainable method of addressing these problems by capturing rainwater and making it available when required. Water harvesting refers to the collection and storage of rainwater from rooftops, fields, roads and other surfaces for future use or for replenishing groundwater. Common methods include rooftop rainwater harvesting, farm ponds, check dams, percolation tanks, recharge pits, contour bunding and small reservoirs. These techniques are particularly useful in drought-prone rural and semi-arid regions where rainfall is seasonal and irregular. One major advantage of water harvesting is that it increases the availability of water during dry periods. Rainwater received during the monsoon can be collected and stored in tanks,
