Climate Change and Water

The impacts of climate change are felt through water. Climate-driven changes to the hydrological cycle will increase the force of rainfall, reduce the reliability of monsoons, prolong droughts in semi-arid regions and reduce water storage in snow and ice.



SIWI works with actors to integrate water and climate policies as a way to support community resilience and sustainable growth. We do this by:

  • Generating knowledge on the linkages between climate change and water across sectors, and the role of water in adaptation and mitigation
  • Raising awareness of the impact of climate change on water in all sectors and how to adapt
  • Creating platforms to exchange experiences, knowledge and perspectives on water and climate
  • Building capacity in organisations to account for climate change in project planning, strategies, policies and laws.

Our services

Through applied research, advisory services and capacity building modules, SIWI’s water and climate specialists work with partners and clients in three main areas:

Climate adaptation policy and programme support
SIWI provides technical support to governments and other partners to integrate water resource management and climate adaptation and mitigation plans and measures. SIWI also helps to improve the understanding among policy makers and practitioners of functional adaptation practices on local level and their policy linkages to national and global levels.

Water and climate economics
Applying economic principles in climate change is useful for making a better valuation of the benefits to be achieved from adaptation and mitigation measures, and also to estimate the cost of inaction. Through this analysis, we support actors to select and apply suitable tools and incentives to effectively implement their adaptation and mitigation plans.

Vulnerability and options analyses for climate change adaptation
Adaptation to climate change requires no/low regret investments for sustainable development, where adaptation options become integral parts of the development plans. SIWI performs analyses to assess socio-economic vulnerability and show where and how adaptation investments can most effectively enhance the resilience of communities.
