Water security-the availability of an acceptable quantity and quality of water for health, livelihoods, ecosystems, and production, coupled with an acceptable level of water-related risks to people, environments, and economies is crucial to Peru's path to shared prosperity while addressing climate risks. Access to this precious resource, however, is increasingly threatened by climate change, pollution, and uncontrolled and inefficient use of existing water resources and infrastructure. Taking strategic action now is critical to ensuring that Peru can sustain its water resource base, continue to deliver water to people and productive sectors of the economy, and build resilience to climatic and non-climatic events.
