“…The evidence is often felling trees prior to land development, very little differentiation in the selection of species in the case of park greenery and squares, no reference to contemporary environmental problems (climate change, environmental pollution), no reference to contemporary pro-ecological design (NBS application). There is a need for a different approach to designing public space in towns [70][71][72][73][74][75][76][77][78]84,120,121].…”

“…Recent trends in revitalization policies take into account the need to apply naturebased solutions [70][71][72][73][74][75][76][77][78], as critical components of sustainability transitions [71], climate change mitigation, and adaptation strategies [79][80][81][82][83][84], important also for small municipalities [85][86][87][88][89][90]. The benefits of nature-based solutions are still not recognized enough in urban planning policies of cities [74]. There are still gaps and barriers in the impact assessments of nature-based solutions, however, it would be an essential part of promoting this concept and approach [70].…”

Revitalization of Public Spaces in Cittaslow Towns: Recent Urban Redevelopment in Central Europe

Revitalization of cities varies depending on the scale of a city, type of challenges, and the socio-environmental context in each case. While revitalization projects carried out in globally known cities are well described, there is still a gap in characterizing revitalization processes that aim to improve quality of life in smaller units like medium-sized towns. This paper fills this gap by the insight from 82 revitalization projects implemented in 14 towns of Warmia and Mazury region (Poland) which are associated in the Cittaslow movement. The study combines a quantitative assessment of statistical data describing these projects with their qualitative evaluation based on interviews with local experts. The results of conducted analyses show that socio-economic development plays a major role as, despite projects which directly refer to the social domain, social elements were found also in projects initially categorized as those targeted to architectural and spatial domains. On the other hand, the authors observed that environmental and ecological as well as cultural issues are treated unevenly or marginally in projects compared to social ones. Interviews with experts show that the least importance was assigned to cultural and historical domain. The obtained results might constitute important knowledge to understand the background of current revitalization processes outside of global metropolises to improve future mechanisms supporting urban renewal.

“…Consequently, the incorporation of NBS in the urban agenda is essential to move towards a more sustainable planning approach. Furthermore, the incorporation of these concepts in policy and planning instruments, such as municipal master plans, in a clear and comprehensive way presents as an essential move that must be promoted by both social and environmental scientists [59,60].…”

The Institutionalization of Nature-Based Solutions—A Discourse Analysis of Emergent Literature

et al. 2020

The European Union quickly incorporated the concept of nature based-solutions (NBS), becoming a key promotor. This was achieved through financial support for both academic research and city implementations. Still, the processes of institutionalization are yet to be fully explored. This study aims at assessing how the scientific literature regarding NBS is addressing institutional aspects and how it is constructing the NBS narrative. This research is divided into two stages. First, it undertakes a quantitative analysis of the discourse, considering a set of preselected search terms organized into five categories: Actor, institutional, planning, policy, and regulation. Second, it adopts a qualitative analysis considering both a group of the most cited articles and of articles highlighted in the previous stage. The results indicate that the NBS concept is still shadowed by other environmental concepts such as ecosystem services. Despite being an issue promoted at the European level, the results of this exercise express the lack of concrete planning and policy recommendations, reflected by the absence of terms such as “planning objectives”. This pattern occurs in all other major categories, being the institutional category the least mentioned of all five categories. The results highlight the need to address both policies and planning recommendations more concretely, studying the institutional arrangements able to promote NBS.

“…One of the critical aspects related to resilience is climate change adaptation. This can include physical measures such as dikes or dams, but increasingly nature-based solutions are sought [79,80], and remote sensing has shown its utility in monitoring many relevant indicators [81]. In coastal communities such as the ones studied in this work, which are subject to rising sea levels, salt water intrusion, and regular tropical storms, image data have tremendous potential in detecting and quantifying adaptive measures, such as vulnerable crops (e.g., coconut palms) getting replaced by more resilient solutions, or protective mangrove corridors getting reinstated.…”

Evaluating Resilience-Centered Development Interventions with Remote Sensing

Natural disasters are projected to increase in number and severity, in part due to climate change. At the same time a growing number of disaster risk reduction (DRR) and climate change adaptation measures are being implemented by governmental and non-governmental organizations, and substantial post-disaster donations are frequently pledged. At the same time there has been increasing demand for transparency and accountability, and thus evidence of those measures having a positive effect. We hypothesized that resilience-enhancing interventions should result in less damage during a hazard event, or at least quicker recovery. In this study we assessed recovery over a 3 year period of seven municipalities in the central Philippines devastated by Typhoon Haiyan in 2013. We used very high resolution optical images (<1 m), and created detailed land cover and land use maps for four epochs before and after the event, using a machine learning approach with extreme gradient boosting. The spatially and temporally highly variable recovery maps were then statistically related to detailed questionnaire data acquired by DEval in 2012 and 2016, whose principal aim was to assess the impact of a 10 year land-planning intervention program by the German agency for technical cooperation (GIZ). The survey data allowed very detailed insights into DRR-related perspectives, motivations and drivers of the affected population. To some extent they also helped to overcome the principal limitation of remote sensing, which can effectively describe but not explain the reasons for differential recovery. However, while a number of causal links between intervention parameters and reconstruction was found, the common notion that a resilient community should recover better and more quickly could not be confirmed. The study also revealed a number of methodological limitations, such as the high cost for commercial image data not matching the spatially extensive but also detailed scale of field evaluations, the remote sensing analysis likely overestimating damage and thus providing incorrect recovery metrics, and image data catalogues especially for more remote communities often being incomplete. Nevertheless, the study provides a valuable proof of concept for the synergies resulting from an integration of socio-economic survey data and remote sensing imagery for recovery assessment.
