Nature-Based Solutions (NbS) have established themselves as a key strategy to address the contemporary challenges of modern cities. By integrating into the three basic pillars of sustainability—economic, environmental, and social—these solutions offer multiple benefits that are essential for sustainable urban development.
Economic Benefits of NbS
The implementation of urban green infrastructures, such as living walls and green roofs, not only beautifies cities but also has a positive economic impact. These projects can attract investments, increase property values, and reduce costs related to energy and water management. Additionally, they foster job creation in the green economy sector, which has experienced significant growth in recent years. This growth is redefining technologies and content, orienting them towards a low-carbon economy.
Environmental Impact of NbS
NbS are fundamental to improving various environmental indicators. Green infrastructures contribute to air quality by acting as natural filters that trap pollutants and produce oxygen. Moreover, they promote biodiversity by creating urban habitats for various species, improving the health of local ecosystems. These green spaces also play a crucial role in climate change mitigation, as they help reduce the urban heat island effect and efficiently manage rainwater, thereby decreasing the risk of flooding and promoting aquifer recharge.
Social Benefits of NbS
In the social realm, NbS enhance the quality of life for citizens by providing accessible green spaces that encourage physical activity, reduce stress, and improve overall well-being. These spaces can also serve as community gathering places, strengthening social fabric and promoting greater cohesion among residents. Furthermore, the creation of green infrastructure can incentivise citizen participation in community projects, generating a sense of belonging and responsibility towards the urban environment.
Measuring Sustainability through Green Infrastructure
The presence and quality of urban green infrastructure are key indicators in measuring a country’s sustainability. Factors such as air quality, biodiversity, environmental health, ecosystem vitality, and climate change adaptation capacity are directly influenced by the implementation of NbS. These indicators not only reflect a nation’s environmental state but also affect its attractiveness and competitiveness on a global level.
Creating a Green Jobs
The focus on NbS drives the creation of a labour sector linked to the green economy. This sector not only provides employment but also promotes the development of skills and specialised knowledge in sustainable technologies. The green economy is redefining educational and technological content to adapt to the needs of a society seeking to reduce its carbon emissions and adopt more sustainable practices.
Nature-Based Solutions are a powerful tool for driving urban sustainability. By integrating economic, environmental, and social benefits, NbS not only improve the quality of life for citizens but also contribute to the resilience of cities in the face of environmental challenges. Urban green infrastructure stands as an essential component in measuring a country’s sustainability, highlighting its importance in the transition towards a low-carbon economy. Implementing and promoting NbS is, undoubtedly, a crucial step towards a more sustainable and liveable future for all.
