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.

As the countries' comments clearly showed, they remain trapped in outdated views about water and nature. They still cling to the illusion that everything will stay the same for centuries. We need to speak with much stronger arguments to bring them back to reality. If the current policies continue to undermine biotic regulation and green water flows, the blue water (rivers) will end unexpectedly as in Iran! According to Victor Gorshkov's calculations in just 4 years it will stop restoring rivers, soil and glaciers- rivers will just flow into the ocean,Best regards,Bulat K. YESSEKIN
