“…Alternatives 6 and 7 provided a higher reduction in all the rainfall events (Table 4). Results stress that NBS will reduce the damage of the residents located in the critical flood areas, being particularly important since not always the reduction of flood depth will reduce the number of properties exposed to the risk, which brings the robustness into the proposal of NBS (Ashley et al 2020).…”

Nature-Based Solutions (NBS) support the provision of multiple benefits for the environment and society. First idealised in 2008, NBS are recommended by worldwide reports and guidelines as strategies to protect, sustainably manage and restore ecosystems. However, their operationalisation is still in the early stages, especially in developing countries, and only a few studies consider their full potential. This article contributes to this context by developing an integrated framework, with spatial and participatory tools, for analysing flood risk mitigation in Brazil. The approach enables a deep understanding of the societal challenges and vulnerabilities of the area (i.e., NEEDS) for subsequently planning the appropriate NBS (i.e., ACTIONS), with the participation of 255 stakeholders of Campina Grande municipality. Results show mappings of flood-prone areas, in which approximately 52% of the flooded areas will have an increase in the future. Hotspots (i.e., hazard, vulnerability, and exposure) are shown and discussed with four application cases. Finally, multiple benefits of seven NBS alternatives are analysed in 53 scenarios of application, in which the higher rates of reductions are found to combined alternatives. The discussion emphasizes the importance of spatially assessing the ‘needs’ and ‘multiple benefits’ of NBS, including reducing vulnerabilities and increment of resilience.

“…As urban planning needs to consider the spatial extent and variation of the rivers, which can be directly linked to the uncertainty zone output of the new tool, there is an opportunity not only to link this uncertainty directly to resilience management and approaches (cf. Ashley et al, 2020), but also to facilitate resilience thinking and communication.…”

<p>River flooding and urbanization are processes of different character that take place worldwide. As the latter tends to make the consequences of the former worse, together with the uncertainties related to future climate change and flood-risk modeling, there is a need to both use existing tools and develop new ones that help the management and planning of urban environments. In this article a prototype tool, based on estimated maximum land cover roughness variation, the slope of the ground, and the quality of the used digital elevation models, and that can produce flood ‘uncertainty zones’ of varying width around modeled flood boundaries, is presented. The concept of uncertainty, which urban planners often fail to consider in the spatial planning process, changes from something very difficult into an advantage in this way. Not only may these uncertainties be easier to understand by the urban planners, but the uncertainties may also function as a communication tool between the planners and other stakeholders. Because flood risk is something that urban planners always need to consider, these uncertainty zones can function both as buffer areas against floods, and as blue-green designs of significant importance for a variety of ecosystem services. As the Earth is warming and the world is urbanizing at rates and scales unprecedented in history, we believe that new tools for urban resilience planning are not only urgently needed, but also will have a positive impact on urban planning.</p>

“…Further, making these changes influences the use of urban areas for different users, and increasing our knowledge on the use aspects is nec-essary for better integration with urban spaces in the future. While previous research has mostly focused on hydrological efficiency, adaptability and spatial morphology of blue-green infrastructure (i.e., Ashley et al, 2018;Bacchin, 2015;Haghighatafshar, 2019;Radhakrishnan, Pathirana, Ashley, Gersonius, & Zevenbergen, 2018), knowledge about social dimensions remains quite vague and needs to be developed further (Ashley, Gersonius, & Horton, 2020;Gandy, 2014). A variety of different values can be recognised as important for blue-green infrastructure, and these vary between different stakeholders.…”

This article aims to understand how the introduction of blue-green solutions affects ethical concerns and expectations of an urban environment. Blue-green solutions are complementary technical solutions, introduced into urban water management, in order to deal with the impact of urbanisation and climate change. These kinds of solutions establish new affordances that have an impact on everyday life in the urban environment. This article describes how blue-green solutions become part of urban settings and how they influence the inhabitant’s perceptions, desires and matters of care concerning these settings. The article examines the interplay between blue-green technologies and the social, material and cultural context in the Augustenborg district in Malmö, Sweden. The study is based on the analysis of free-text answers to a questionnaire aimed to collect information about the interaction between blue-green solutions and everyday life in public spaces. By exploring the inhabitants’ point of view, the article then seeks to recognise the meanings and thoughts entangled with place concerning different types of blue-green solutions. We summarise the main concerns raised by the inhabitants and discuss how the implementation of blue-green solutions relates to the transformation of everyday ethicalities and matters of concern relating to the neighbourhood. We conclude that blue-green infrastructure seems to come with a new kind of sensitivity, as well as with an intensification of concerns, in an existing urban environment. This has important social repercussions, which also makes it important to study the social role and implications of blue-green technologies further.
