Around the world, 2.2 billion people live without access to safe water. As we mark World Water Day on 22 March, it is a moment to recognize the central role that water plays in accelerating the achievement of the Sustainable Development Goals (SDGs). UN Resident Coordinators bring together UN country teams and partners to support the work of governments and communities in boosting access to safe water. They mobilize resources to tackle water scarcity challenges, ensuring that access to safe water remains a top policy priority. Their engagement focuses on several fronts, from tackling the impact of climate change on water resources to water conservation to boosting public health and community resilience.
