- Stakeholders’ perceptions of appropriate nature-based solutions in the urban contextPublication . Ferreira, Vera; Barreira, Ana; Loures, Luís; Antunes, Dulce; Panagopoulos, ThomasThe concept of nature-based solutions (NBSs) has become increasingly popular among urban policymakers and planners to help them tackle the urban challenges arising from urban expansion and climate change. Stakeholders' involvement is a fundamental step, and stakeholders' perceptions and preferences can affect the development of NBS projects. This study aims to identify stakeholders' perceptions of the most critical urban challenges, the priority interventions, the preferred NBSs and the benefits of the NBSs, and to identify the determinants of these perceptions. A survey was administered to assess stakeholders' perceptions and views on implementing NBSs in two Portuguese cities with distinct urban, geographical, and socio-economic contexts. A binary logistic regression model was used to understand the determinants of the likelihood of the stakeholders' answers. According to the stakeholders, climate change is one of the main concerns in the urban context. It is usually associated with the incidence of heatwaves and water scarcity. Additionally, stakeholders are concerned about the low quantity and poor management of green spaces (GSs). They believe that it will be necessary to increase the GS, to recover some degraded areas, and to increase mobility. The preferred NBSs were planting more urban trees, making green shaded areas, and rehabilitating riverbanks. The main expected benefits were benefits for leisure and relaxation, reductions in air temperature, purer air, and improvements in public health. The results showed mostly coherent connections between the main concerns/priorities of the stakeholders and the perceived NBS benefits; however, some stakeholders did not present coherent connections, indicating low awareness of the current policy for implementing NBSs to overcome existing and future urban challenges.
- Understanding attitudes towards the adoption of nature-based solutions and policy priorities shaped by stakeholders’ awareness of climate changePublication . Ferreira, Vera; Barreira, Ana; Pinto, Patrícia; Panagopoulos, ThomasClimate change is affecting cities worldwide. Accordingly, cities are required to find sustainable solutions to tackle climate change's effects, designing bottom-up policies to enhance their success. The involvement of stakeholders plays a central role in the definition of appropriate policies to tackle the challenges posed to cities by climate change. Nature-based solutions (NBS) are increasingly proposed to adapt to and mitigate the adverse effects of climate change. This study aims to assess the coherence of the policies emerging from stakeholders' perceptions of urban climate challenges and their preferred NBS to tackle them. Indeed, it considers whether departing from different urban climate challenges, stakeholders' choices present a coherent articulation between priority interventions, proposed solutions and expected benefits. Using a survey applied to two Portuguese cities and the chi-squared automatic interaction detector (CHAID) algorithm, we analyse the answers provided by stakeholders. The stakeholders' perceptions and preferences were not significantly influenced by their hierarchical position in their institutions, their city's location and socioeconomic setting. Heatwaves and temperature rise together with drought and water scarcity are identified as future urban challenges in Portugal. Priority interventions, as well as preferred NBS and their expected benefits, are addressed. The results show that stakeholders may make decisions that form a coherent policy, in which acknowledgment of climate change's effects interconnects with related priority interventions, suitable NBS and their benefits.
