The effects of climate change are most acutely felt through the presence of water – either too little or too much of it. In some areas, rising temperatures cause prolonged periods of drought, which challenge the availability of fresh water resources. In other areas, the occurrence of more extreme rain events lead to severe flooding which – in addition to the immediate risk to humans – pose a significant risk of damage to critical water infrastructure and can result in contamination of water sources.
Water plays a crucial role in how we mitigate and adapt to the effects of climate change. Well-planned climate change adaptation initiatives can reduce the negative social, environmental and economic impact of climate change. A holistic approach, which also links to urban development and urban water management, can result in both climate resilient and more liveable cities.
Water for smart 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.
New EU rules aim to ensure better drinking water and less waste
New EU directive map out how drinking water quality and supply can improve across the EU. Denmark has helped to focus on water waste in the revised EU directive aimed at ensuring consumers healthy and clean drinking water.
World Water Day 2020: climate change will affect water the most
While climate change greatly affects water supply around the world, ensuring a more dependable and efficient water supply can limit CO2 emissions. This World Water Day revolves around the theme of climate change and water – a theme to be further discussed at the IWA World Water Congress 2020 in October in Copenhagen, Denmark.
Nature Based Solutions
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 […]
Refrigeration plants and flood warning to mitigate climate impacts in developing countries
Two partnerships with Danish participation are supported by P4G – Partnering for Green Growth and the Global Goals 2030 – to find solutions to curb the consequences of climate change in Africa and Asia. The solutions are based on new technology and local cooperation in developing countries.
Extreme Weather Has Been Expensive for Denmark
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.
Cleaning urban road runoff with new green technology
A unique water treatment plant has seen the light of day. The innovative cleaning technology is the first large-scale attempt to solve the challenges cities face with road runoff that pollute the aquatic environment and groundwater or that has to be pumped all the way through cities to be cleaned at sewage treatment plants.
Adapting to the Future Climate
Global climate changes will set their marks on Copenhagen over the next 100 years: Dry summers with intensive rainfall, wetter winters, higher temperatures and rising water levels. To safeguard Copenhagen and prepare the city for the changing climate, the city of Copenhagen has produced a climate adaptation plan. With long-term investments and timely planning, we will have the required edge to […]
Musicon – skate park as flood mitigation
Storm water solutions with multiple purposes are implemented in this new developed area in Roskilde. The area was former used for a huge concrete factory. When the factory moved out of the city the area was transformed to an area used for many activities as living, exhibitions, sport, art, music and other cultural and recreational […]
3 examples of holistic urban solutions: a water & climate adaptation perspective
Our cities are growing and so is the need to make them more sustainable and liveable. In this month’s article, we gather 3 examples of holistic urban solutions from a water and climate adaption perspective that contribute to creating liveable cities.
Flood Warning in Copenhagen, Denmark
In July 2011 Copenhagen experienced the worst rainfall ever with more than 80,000 homes flooded resulting in damages at a cost of around 1 billion €. A new tool has been developed in order to minimize damages from such events in the future. Quick solution to combat effects of climate changes With the climate changes, some […]
Rockflow for water management – natural solutions for sustaining water resilience
The climate is changing: how do we manage extreme rainfall? Not only more rain is falling due to climate change, but rain showers are often more extreme. This means that a lot more water has to be collected and disposed of in a short time. In the countryside this is not usually a problem, but it is more so in the increasingly urbanised environment.
Cloudburst Mitigation Plan for Copenhagen
Less flooding and more blue-green recreational areas. This is the ambition for the cloudburst mitigation plans in the Danish capital. The innovative plans provide a view into the future for cities around the world. The Danish capital’s cloudburst mitigation plans are focused on solving increased heavy rain challenges, climate adaptation of the sewerage systems, as […]
The Five Gardens (Digterhaven) exploit torrential rains
The City of Sønderborg repeatedly had problems with flooding due to heavy rain. In September 2012, the utility company Sønderborg Forsyning therefore started to build five rain gardens which were to delay the rainwater from cloudbursts and help to prevent future flooding. Instead of direct rainwater to the sewer, the rainwater was used as a […]
