Developing solutions that enable cities to withstand the threats of rising sea levels and extreme weather events
Cities around the world increasingly face pressure from both growing populations and climate change. In addition to dealing with the effects of urbanisation and increased population density, cities also need to develop solutions that enable them to withstand the threats of rising sea levels and extreme weather events. An integrated approach to urbanisation and climate change can ensure cost efficiency and synergies in terms of greater value from urban development investments. Through public-private collaboration and long-term holistic planning, many Danish cities have achieved this and at the same time gained greater public support and more liveable cities.
We invite you to explore solutions related to integrated urban water management in more depth below, find potential partners, catch up on the latest related news and discover real-life case examples of how flood integrated urban water management can help solve your environmental challenges.
Challenge Many cities today suffer from Urban Heat Island effect (UHI) and excess of rainwater runoff in the streets, creating challenges for liveability and causing costly damages to infrastructures. These problems will only grow in the future, as extreme weather events are happening more frequently around the world – and cities with a growing population […]
Cities around the world increasingly face the adverse effects of climate change, including rising sea levels, climbing temperatures, longer periods of drought and stronger storms. The majority of cities have no plans for climate resilience set in place to mitigate the effects of extreme weather-related events, even though we already have most of the solutions available.
Water hazards like floods, extreme rainfall, and droughts can have detrimental impacts on local communities and their economies. Recovering from these impacts might be very difficult, especially in cities where communities live closely together and systems are interconnected. Luckily, there are many solutions that can help cities build resilience.
Texas is currently home to 16 of the hottest cities in the US, and researchers predict that temperatures will continue to skyrocket, creating the detrimental “urban heat island” effect. This could have huge negative social and economic impacts for communities living in the cities. Fortunately, many solutions can help build resilience towards hazardous heat in the cities.
Good rainwater management can make cities healthier places to live, resilient towards climate change and more sustainable overall. Population growth and urbanisation, floodings as well as more frequent and longer periods of droughts all encourage an optimised use of rainwater in cities. Traditionally speaking, climate adaptation seeks to lower the risks posed by the consequences of climate […]

How important is access to clean air in our cities? And how valuable is access to clean water and proper sanitation to city life? Both air and water are under pressure in our cities as a result of increasing urbanisation, and the human and economic consequences are immense. However, many solutions to tackle the challenges already exist – and maybe the time has never been better to speed up the transition to a cleaner and more sustainable future?
The housing development Urbanplanen has a green secret: in between the large buildings, there are cherry plums, hazel and birch trees, and at the staffed playground, Bonderen (the Farm), goats graze. Remiseparken is a wonderful green pocket in Copenhagen, and the goal of BOGL’s renewal project was to transform the park into a safe and attractive destination for local residents and other Copenhageners.
The climate crisis is accelerating at an unprecedented rate but urban climate adaptation plans are failing to keep up with the pace. 75 per cent of all European cities have no climate adaptation plans as we speak. In Copenhagen, several climate change initiatives have been taken and more projects are underway.
A brand new publication from State of Green – created in cooperation with International Water Association Denmark (IWA Denmark) – takes a closer look at how rethinking urban water management can transform cities of the future. The white paper is meant to serve as a tool for inspiration for creating innovative water solutions, which contribute to smarter and more liveable cities.
Good water management can make cities healthier places to live, resilient towards climate change and more sustainable overall. Without proper sanitation, sewerage and clean water supply, there is no liveable city. This white paper features lessons learned from different Danish stakeholders within urban water management. It is meant to serve as a tool for inspiration for creating innovative water solutions, which contribute to smarter and more liveable cities.
Billund BioRefinery (BBR) is a resource recovery plant that integrates urban waste management and wastewater treatment with circular economy. We produce energy, clean water and nutrient rich natural fertilizer, all whilst effectively cleaning all the influent waste streams and protecting the environment.
Architecture can reduce the climate footprint and protect buildings and urban areas against climate change. Climate change calls for stronger initiatives in the building and construction sector – both to promote broader use of sustainable solutions and to make our buildings and cities more resilient to climate change.

Over the last 39 years, the cost of extreme weather and climate events in Europe has been EUR 453 billion. Compared to the number of citizens and land area, Denmark has paid the second highest price. However, it is predicted that the costs in the future will be lower as the country has become better at protecting its values after the cloudburst in Copenhagen, 2011.
Streets constitute a significant share of the total surface area of Danish cities. In terms of elevation they literally form the bottom line. Schulze+Grassov are under contract with Denmark’s Realdania Foundation under the Danish Klimaspring initiative to develop new innovative climate adaptation systems. Working creatively with streets in urban environments we seek to turn a […]

Urban water systems – for drinking water provision, wastewater collection and treatment, and stormwater management – are key to human health and environmental protection in cities around the globe. They are challenged by urbanisation, by decades of maintenance and by an increased frequency of floods and droughts due to extreme weather events exacerbated by climate change.
Just a decade ago, most cities saw water as something to hide and remove in sewers. Today, the harbor water in Copenhagen is clean enough to swim in and the area around the Harbour Bath has flourished. This has been achieved through an integrated approach to urban water management, combining a broad range of environmental, economic and social strategies. Although initially more complex, it is ultimately more cost-efficient from an overall societal perspective.
When investments in blue infrastructure are integrated early in the urban planning process, synergies can be achieved and costs reduced. Moreover, in order to meet the future demand for water, there needs to be a strong focus on efficient water management, operation and not least a focus on reducing Non-Revenue Water (NRW). Overcoming barriers to reduce NRW requires attention and involvement from several stakeholders – from politicians to local consumers – as well as new partnerships. The right political framework can create incentives for innovation and optimisation, as well as increase public awareness on the value of having a stable and efficient water supply.
Danish experience shows that climate adaptation can also present an opportunity to rethink urban development and gain greater value from investments. Rather than coming at the expense of urban living, climate adaptation can contribute to greener and more liveable cities. For instance, instead of expanding the underground sewage system, surplus water can be led to structures above the ground such as green beds, canals or lakes around the city. These serve a dual purpose as they – in addition to increasing the stormwater drainage capacity – also function as recreational areas, which help cool the city and increase biodiversity. It can be a great way to pursue a better way of moving than the new way of doing it.
