In response, urban greening and nature-based solutions (NbS) have emerged as key approaches for reducing risks from multiple types of extreme climate and weather events while making a positive impact on urban social and environmental inequities. NbS interventions are high on urban agendas worldwide, but in practice, they often are hyper-local and contain novel ecological entities, with unknown capacity to deal with different pressures and disturbances. Thus, there is an urgent need to build knowledge around how, when, and under what circumstances different NbS can be expected to perform their functions as intended. One step towards building, and then constantly updating, such knowledge is to establish practices for monitoring and evaluating NbS.</div><div>In this study, we showcase a novel approach based on wireless sensor technology that harnesses hyperlocal data in real time to understand the direct impact of NbS on the local climate across seasonal variation and under extreme weather conditions. We aimed to quantify to what extent NbS are contributing to ecosystem services such as cooling.</div><div>To answer this, we installed eighteen microsensor weather stations across the biggest and most recent sustainable urban development in Sweden - Stockholm Royal Seaport. We investigated five distinct types of NbS - forest parks, green courtyards, rain gardens, green roofs, and lawns, during the summer of 2021 to examine whether real-time temperature changes varied between NbS site types. Despite large differences in vegetation and urban landscape, we did not observe a clear trend in air temperature differences between sites, even for experimental reference sites. Our analysis reveals that forest parks are the coolest and the green roofs are the warmest green places overall. The largest differences in daytime temperatures reached up to 2 °C difference between sites in summer, which gradually disappeared during cooler months. Our results suggest that regional weather dynamics dominate over the Stockholm Royal Seaport's micro-climate, leading to a relative similarity in NbS cooling performances. Though the district overall may be too homogeneous to affect air temperature variation and local NbS too small to alter the regional weather patterns, we nonetheless conclude that ecosystem services of NbS should not be taken for granted. Results suggest that NbS interventions, almost regardless of type, need to be considered and implemented at larger district scales to add up to the substantial total green cover needed to impact local and regional temperatures.</div></div>","PeriodicalId":100945,"journal":{"name":"Nature-Based Solutions","volume":"7 ","pages":"Article 100206"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143145749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The International Union for Conservation of Nature (IUCN) has developed eight criteria for identification of Nature-based Solutions: (1) address societal challenges (2) entail landscape scale of intervention (3) biodiversity gain (4) economic viability (5) governance capability (6) equitably balance trade-offs (7) adaptive management, and (8) mainstreamed within an appropriate jurisdictional context. Nevertheless, studies have shown that interventions that seek to help people in the frontlines of climate change often fail to provide predictable financing, enable local ownership, and align to the actual conditions of the local communities. To address these challenges, in 2018 more than 20 countries formed a global commission on adaptation, which in 2021 adopted eight guidelines known as Locally Led Adaptation (LLA) principles to guide climate change adaptation efforts by ensuring that local communities are empowered to lead the design, implementation, and decision-making processes for adaptation projects. While NbS offer substantial co-benefits—enhancing biodiversity, supporting livelihoods, and improving water security—their success hinges on effective financing, governance, and local engagement. Sand dams, in particular, have been implemented for decades across arid and semi-arid regions, offering a reliable method of water harvesting and climate adaptation. However, their integration into NbS frameworks and LLA principles remains underexplored. As such, this study sets out to assess how one of the sub-national governments of Kenya (Makueni County) has aligned its implementation of Nature-based Solutions to the principles of LLA. The NbS under consideration is the county's sand dam project, which was instituted to address water scarcity in the face of climate change and inadvertently disaster risk management. To gauge the NbS project's alignment to LLA principles, 43 indicators and measurement metrics were developed based on the eight principles of LLA. Each principle has between 4 and 7 qualitative indicators. Data was collected through focus group discussions with sand dams’ projects’ committee members, key informant interviews with county and national government officials responsible for water and climate change, and analysis of the sand dams’ projects documents. Each indicator was assigned a score of 1 if present and 0 if absent, giving a potential of 43 positive scores or 100 % if the county government scored 1 for all the 43 indicators. From indicators assessed, the County Government had a positive score in about 53 %, slightly above average (50 %).

First, we provide an evaluation of the monitoring processes, the performance on the NbS and the assessment of the NbS impact. The European projects framework provides a wide number of examples of NbS implementation and in the case of this paper, as is the case for the project on which this report is based.

The assessment has been conducted considering two main sources of information: 1) Evaluations developed during the initial phases of the project and the weights assigned to each variable under study, including the prioritization of the KPIs for each NbS implemented in each demo city and the evaluation of the potential impact that those NbS produced on several city challenges. 2) The monitoring of the NbS implemented and data collected, which has provided the assessment of combined impact of each NbS regarding city challenges. Likewise, the paper describes the methodology applied to make the overall assessment of the NbS through the performance of the KPIs. Additionally, we show the data an analysis of the technical, economic, social and environmental barriers, boundaries appeared in the course of KPI monitoring, and NbS implementation phases in demo sites.

To explore transformative nature-based built environment design agendas that link closely to Indigenous ecological knowledge and understandings of wellbeing, research was carried out through a series of interviews and workshops with local people.

We discuss using the Mauri Ora compass research co-design methodologies to bridge cultural differences, political agendas, and varying worldviews and encourage meaningful engagement with eco-centric local and/or Indigenous communities. Key findings include that the communities engaged with, who are largely Kanak, see that fundamental changes must occur in the design and construction of built environments, and that the nature of the changes is not just technical, but fundamentally requires a cultural shift in how people understand themselves to be in and of the living world.

However, coastal land regions that are protected by dykes experience major hydrodynamic changes after breaching. To investigate these dynamics, a dyke in Atlantic Canada was purposefully breached and the adjacent land surface allowed to flood with the tides. Field measurements pre- and post-breach provide a rare opportunity to model the hydrodynamics of early dyke realignment in a hypertidal estuary in the Bay of Fundy. These include measurements of water levels and current velocities at spring tide collected across of field site. A numerical model with an unstructured flexible mesh (Delft3D-FM) was applied to examine the impacts of tidal flooding from a river channel, through the dyke breach and across the previously agricultural landscape that was historically a salt marsh. The model was used to simulate the hydrodynamics inside and around the breach before and after seawater flooding during spring tides, to evaluate the initial impacts of this nature-based method of managed dyke realignment. The results indicate that the breach was not wide enough to influence water levels within the Missaguash River. The depth-averaged current speeds can exceed 1 m <em>s</em><sup>−1</sup> within the breach and are typically <0.3 m <em>s</em><sup>−1</sup> across the flooded area with an average depth of 0.66 m over the simulation period with six tidal cycles. The model results also highlight the importance of high-resolution computational grids and variable bottom roughness for simulating the hydrodynamics of small-scale salt marsh restoration projects.
