Enhancing Ecosystem Services and Climate Change Adaptation through Nature-Based Solutions and Green and Blue Infrastructure: Design and Planning Case Studies from Urban Areas in Lombardy region, Italy.

It is evident that both NBS and green and blue infrastructure represent innovative strategies for addressing environmental challenges in urban areas, especially in the context of climate change. These approaches have the potential to not only mitigate the effects of climate change, but also contribute to enhancing the quality of urban life.

NBS is predicated on the utilisation of solutions that are inspired by, or based on, natural ecosystems. These solutions have utility in addressing contemporary issues such as water management, pollution reduction and biodiversity conservation.

Urban areas are especially susceptible to the repercussions of climate change, including rising temperatures, amplified heat islands, extreme weather events, and flooding. It is evident that NBS and green and blue infrastructure have the capacity to play a pivotal role in the mitigation or adaptation to these phenomena. For instance, green spaces such as parks assist in mitigating the urban heat island effect by providing shade and cooler temperatures, while green-blue infrastructure facilitates more efficient stormwater management, thereby reducing the risk of flooding.

It is an established fact that NBS and green and blue infrastructure provide a range of essential ecosystem services. NBS and green and blue infrastructure provide a range of essential ecosystem services. For instance, climate regulation is achieved through the absorption of carbon dioxide by plants, thereby reducing the impact of greenhouse gases. Furthermore, the purification of air and water is facilitated by ecosystems, which act as filters for pollutants and thereby enhance water quality. Additionally, biodiversity is promoted through the creation of habitats, which serve as refuges for various animal and plant species, thereby fostering urban biodiversity.

In urban areas, which are increasingly vulnerable to climate change, the integration of nature-based solutions and green and blue infrastructure is imperative. These approaches have been demonstrated to assist in the mitigation of the risks associated with extreme weather events, whilst concomitantly offering opportunities to enhance urban quality of life and promote sustainability. Investment in such strategies is considered a prudent decision for the cities of the future, as it will contribute to the creation of more resilient and liveable environments.

The present contribution offers a series of case studies drawn from Italy, focusing on the implementation of NBS and green and blue infrastructure within urban contexts in Lombardy, with a particular emphasis on the city of Milan.
