Physical water scarcity occurs when there is not enough water to meet demands. Economic water scarcity occurs when water resources are available, but there is a lack of investment in infrastructure to make the water accessible to people. This distinction impacts water management strategies, as physical scarcity requires conservation and supply augmentation, while economic scarcity requires investment in infrastructure and governance.

Recent developments include government initiatives to promote water conservation and water harvesting, implementation of water-efficient irrigation techniques in agriculture, and a focus on groundwater recharge and sustainable groundwater management.

Challenges include: lack of awareness among the public, inadequate infrastructure for water harvesting and storage, inefficient irrigation practices, pollution of water bodies, and conflicts over water resources. Effective implementation requires integrated water resource management and community participation.

Integrated water resource management (IWRM) promotes the coordinated development and management of water, land, and related resources to maximize economic and social welfare equitably without compromising the sustainability of vital ecosystems. It helps in addressing water scarcity by ensuring efficient allocation, promoting conservation, and reducing conflicts over water resources.
