How and why European cities turn to nature in the face of climate risk

As the effects of climate change become more apparent, cities around the world are scrambling to adapt. In Europe, many cities are turning to natural solutions (NBS) to help them cope with the challenges of climate change.

NBS are defined as "solutions that use the power of nature to solve societal problems." These can include a wide range of activities such as creating green roofs and walls, planting trees, restoring wetlands and using natural drainage systems.

There are many reasons why NBS are becoming more and more popular in European cities. First, they are often more cost-effective than traditional gray infrastructure solutions. Second, they can provide a wider range of benefits, such as improved air and water quality, reduced heat stress and increased biodiversity. Thirdly, they can be more aesthetic and convenient than traditional solutions.

Here are some examples of how European cities are using NBS to adapt to climate change:

Copenhagen, Denmark: Copenhagen is a leader in using NBS for climate adaptation . The city implemented a wide range of measures, including greening of roofs and walls, planting trees, and using natural drainage systems. These measures have helped reduce the city's heat island effect, improve air quality and reduce flooding.

Rotterdam, Netherlands: Rotterdam is another city using NBS to adapt to climate change. The city has built several floating gardens  which are designed to absorb rainwater and provide wildlife habitat. Rotterdam also uses NBS to create more livable spaces for residents, such as parks and squares.

Berlin, Germany: Berlin uses NBS to cool the city during heatwaves. A million trees have been planted in the city and a number of green areas have been created. Berlin also uses NBS to improve water quality, for example by using constructed wetlands to filter rainwater.

These are just a few examples of how European cities are using NBS to adapt to climate change. NBS is a promising approach to climate adaptation that can provide a wide range of benefits for cities and their residents.

In addition to the above benefits, NBS can also:

Help reduce greenhouse gas emissions by absorbing carbon dioxide from the atmosphere.

Improve public health by reducing the impact of air and water pollution.

Creating jobs in the green economy.

Stimulate the local economy by attracting tourists and business.

As cities around the world continue to grapple with the effects of climate change, NBS is likely to play an increasingly important role in building more resilient and sustainable communities.
