Water security refers to the reliable availability of an acceptable quantity and quality of water for health, livelihoods, and production. It encompasses the management of water resources to ensure that all people have access to safe drinking water and sanitation. This is crucial for sustaining ecosystems and supporting economic development. Factors affecting water security include climate change, population growth, and pollution. Governments, communities, and organizations work together to implement strategies that protect water sources and improve water management practices. Ensuring water security is essential for achieving broader goals like public health, food security, and environmental sustainability.
