Climate Change and Water – 2020 World Water Day

World Water Day 2020, on 22 March, is about water and climate change – and how the two are inextricably linked. Adapting to the water effects of climate change will protect health and save lives. Using water more efficiently will reduce greenhouse gases. We cannot afford to wait. Everyone has a role to play.


Climate is water

The International Water Association (IWA) connects professionals across sectors to deliver water-wise climate solutions.  Water is a connector that offers solutions to global challenges. It is everybody’s business and climate change affect ‘us all.



Water & Climate Change – an Online Discussion

22. March 2020 | 15h00 CET

On the occasion of this international day to celebrate water and raise awareness on the importance of a water-wise world and in the state of minimal travel, the  IWA organises an Online Panel Discussion on the topic.


Climate change and water are inextricably linked. What we do with water in cities can impact climate change, and climate change can impact water and exacerbate water scarcity in cities where people are already lacking access to safe drinking water. Acting now has never had more meaning. There are a number of things we can be doing to take Climate Action in the Water Sector and the time to act is now.

Climate Change and Water – A Story from Denmark

By Carl-Emil Larsen

Water is at the heart of the climate crisis

Climate change poses huge challenges for the water sector as water will become scarcer, more unpredictable, more polluted or all of the above. Our work is crucial to secure adequate adaptation to climate change but we must make the right choices at the right time. “We cannot afford to wait” and “Everyone has a role to play” – These two sentences are among the key messages from UN Water for the World Water Day on the 22 March this year and they reflect discussions in the Danish water sector.




Climate Change: A Threat To Attaining Sustainable Development

By Jacob Amengor

Growing up, I was very familiar with streams and wetlands as my family and I lived in an agricultural research area. My favourite delicacy as a child was taro, which grew all over the marshy areas within the community. I also recollect how the whole community came together to dig shallow dugouts and immediately groundwater built up in the dugout and was used for irrigation purposes. (…)

Water and Climate Change

Climate change most significantly manifests in disrupting the water cycle. Changing weather and water patterns are driving global water scarcity, and increasing the frequency and severity of extreme weather events.  The impacts transverse scales and resiliency at the basin, city and utility level need to be coordinated to ensure adaptation measures are effective.

Nature for Water: A Series of Utility Spotlights

By 2025, two thirds of the world’s population will be living in water stressed conditions. Meanwhile, the degradation of water ecosystems is occurring at alarming rates. Water utilities and water regulators that choose to play an active role in catchment management with nature based solutions (NBS) are uniquely positioned to help. Building a robust knowledge base and supporting opportunities for cross-sector collaboration are fundamental to the mainstreaming of NBS.

The International Water Association (IWA) and The Nature Conservancy (TNC) are working together to encourage and facilitate active utility involvement in NBS, as well as promoting stronger connections between water utilities and regulatory bodies. Implementation of NBS involves multiple, interdependent stakeholders at various governance levels, and consequently regulators a key role in creating the enabling environments for these interactions and negotiations.

Skanderborg Forsyning – Climate Change adaptation using Nature-based Solutions

Skanderborg Forsyning affirms that when it comes to water security in a changing climate, using nature-based solutions at the local level was never a question. Climate change projects are an opportunity to adapt using nature to deal with increased rainfalls and prevent the flooding of urban areas.

Climate: Building resilience through adaptation and carbon neutrality

Climate variability and change is disrupting the water cycle. Changing weather and water patterns are driving global water scarcity, and increasing the frequency and severity of extreme weather events, which has impacts across scales. Resilience is more than implementing the right technology or practice to assess and address risks of extreme events. It is an approach that should be part of a coherent and holistic strategy to ensure sustainable water resources and safe and secure water supply.

Resilience needs to be built and coordinated at the basin, city and utility level to ensure adaptation measures for water systems are effective and integrate with other urban services. With the aim of empowering professionals working at the utility, city or basin level to be at the forefront of climate smart water management, IWA offers the latest knowledge, resources and tools developed, co-designed and tested in collaboration with different end-users.

The Roadmap to a Low-Carbon Urban Water Utility

An international guide to the WaCCliM approach

The Roadmap to a Low-Carbon Urban Water Utility presents utility managers with an approach to address their most pressing challenges, while reducing carbon emissions through measures that either have a return on investment through energy or water savings, or that correspond to planned investments as part of the asset management plan to maintain or improve their services.
