Farhan Haq, deputy spokesman for UN Secretary-General Antonio Guterres, said the plea came in a letter addressed to heads of state and government.
The letter urges governments to more effectively address the water dimensions of climate change adaptation and mitigation.

It seeks to ensure the availability and sustainable management of water and sanitation for all.
