What is water harvesting? List two main advantages associated with water harvesting at the community level. Write two causes for the failure of sustained availability of groundwater.
Water harvesting is the process of collecting and storing rainwater for future use. Two main advantages associated with water harvesting at the community level are: 1. It helps to conserve water and reduce the demand on groundwater resources. 2. It provides a reliable source of water for drinking, irrigation, and other domestic purposes. Two causes for the failure of sustained availability of groundwater are: 1. Over-extraction of groundwater due to increasing demand and lack of proper management. 2. Contamination of groundwater due to human activities such as industrial waste disposal and agricultural runoff.

Analysis & Explanation
Water harvesting is an important technique for conserving water and reducing the demand on groundwater resources. It involves collecting and storing rainwater for future use, which can help to reduce the pressure on groundwater resources and provide a reliable source of water for drinking, irrigation, and other domestic purposes. However, the failure of sustained availability of groundwater can be caused by over-extraction of groundwater due to increasing demand and lack of proper management, as well as contamination of groundwater due to human activities such as industrial waste disposal and agricultural runoff.
