Only 3% of the earth’s water is freshwater; about two-thirds of it is frozen in glaciers and polar ice caps and we have long over-stretched this precious resource.

How we engage

Our work focuses on water governance that integrates the needs of people and nature, the implementation of sustainable water resource management to secure water-related ecosystem services and conserve freshwater biodiversity, and support increased investment in ecosystems as natural water infrastructure.

    Nature-based Solutions for Water

    'Natural Water Infrastructure' refers to services nature provides for free, such as mangroves protecting shorelines from storms, peatlands sequestering carbon, wetlands filtering contaminated water, lakes storing large water supplies, and floodplains absorbing excess water runoff. These water ecosystem services perform an infrastructure-like function and are part of what is termed 'Nature-based Solutions' (NbS).

    Find out what these NbS mean for climate adaptation, built infrastructure, investment opportunities, and much more.

    World Water Day 2020: Investing in water is investing in resilience

    With the onset of the coronavirus pandemic, handwashing to prevent infection has become a number one priority. Yet, access to clean water for handwashing is still a luxury for many. On World Water Day 2020, the need to re-focus on achieving Sustainable Development Goal 6 is more urgent than ever: ‘Ensuring availability and sustainable management of water and sanitation for all’.

    Wetlands and Biodiversity

    On World Wetlands Day, the International Organization Partners to the Convention on Wetlands call for an ambitious Global Biodiversity Framework. 


    As we mark World Wetlands Day under a biodiversity theme, we must all recognise that 2020 provides us with a unique opportunity to make an ambitious global commitment to protect and restore our wetlands and the biodiversity that both depends on and underpins them.

    Sharing the benefits from the river From theory to practice

    With a growing population and a changing climate, the challenge to fairly share available freshwater needs to be addressed urgently.

    Through the BRIDGE 'Building River Dialogue and Governance' programme, the IUCN Global Water Programme and the IUCN Environmental Law Centre have been working towards improved transboundary water governance for the past ten years. Benefit-sharing of water resources is a major component of this work.

    Lake Titicaca - Empowering women and improving water governance

    Lake Titicaca was once worshipped by the Incas who proclaimed its deep blue waters were the birthplace of the sun. Today the lake is heavily polluted.

    This visual feature tells the story of how the BRIDGE project is helping to empower women and improve water governance in the Titicaca basin shared between Bolivia and Peru.

Peatlands and climate change

Peatlands are a type of wetlands that occur in almost every country on Earth, currently covering 3% of the global land surface. The term ‘peatland’ refers to the peat soil and the wetland habitat...

Water and climate change

Water and weather, the delicate balance between evaporation and precipitation, is the primary cycle through which climate change is felt. As our climate changes, droughts, floods, melting glaciers,...
