While blue water, the water flowing through rivers, lakes, and aquifers, has long dominated global water governance, green water, the moisture stored in soils and absorbed by vegetation, remains largely invisible in global water governance and climate frameworks. Yet it plays a vital role in sustaining food production, ecosystem health, and climate resilience.
As climate change intensifies droughts, land degradation, and ecosystem stress, managing green water more effectively is becoming essential to advancing the 2030 Agenda for Sustainable Development and strengthening the water–climate–land nexus, particularly in support of SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action), and SDG 15 (Life on Land).
The Green Water Dialogue is bringing together UNESCO Member States representatives, water and climate experts, development partners, and private-sector and academic actors. The discussion will contribute to shaping UNESCO’s future work on water and resilience under the Intergovernmental Hydrological Programme.
