Urban forests are considered a nature-based solution for climate change by cities and countries worldwide. However, the effectiveness of large-scale urban forest projects as a natural climate solution has been rarely assessed. In this study, we utilized a unique opportunity from Beijing's actions to implement a large urban forest project since 2012 to examine the effectiveness of the proposed solution. We collected vegetation structure data in two extensive field surveys to track the growth of the newly formed urban forest. Using field data and allometric equations, we estimated carbon sequestrated by the urban forest. We found that between 2013 and 2020, the urban forest grew rapidly, with the average increase of DBH and height reaching 0.95 cm and 0.47 m annually, respectively. The 16,667 ha of trees and shrubs sequestrated 423,074 tons of carbon in ten years, or 42,307 tons annually. The result showed that large-scale urban forest projects have the potential to be used as a natural climate solution (NCS). Nevertheless, planning and developing specific management techniques are needed to fully realize this potential.

Nature-based solutions (NbS) are recognized as one of the approaches that can address a range of environmental issues, often with conservation and natural resource management missions. However, the promotion of NbS often lacks a robust understanding of their actual impacts and effectiveness. To support the evaluation and implementation of NbS, there is a need for a comprehensive quantitative assessment framework. The main objectives of the study are to (1) develop an assessment framework that can be used to quantify the performance of NbS interventions and to (2) provide a step-by-step guideline for evaluating NbS. The assessment framework proposed in this study was built upon existing frameworks used in previous studies, designed to address specific gaps. Several aspects and tools were integrated in response to the NbS standard criteria provided by the International Union for Conservation of Nature (IUCN), as a result, this quantitative assessment framework can provide a comprehensive evidence based on environmental, social, and economic aspects. The study introduced one approach, viz., the System of Environmental-Economic Accounting - Ecosystem Accounting (SEEA EA), and three main assessment tools (i.e., Life Cycle Assessment (LCA), Social Life Cycle Assessment (S-LCA), and Cost-Benefit Assessment (CBA)) aimed at facilitating a comprehensive evaluation of NbS. The results provide a conceptual framework that offers a systematic approach for evaluating the performance of NbS, along with methods to address conflicting results among aspects and/or indicators. Ideas and approaches for assessing ecosystem services provided by NbS and primary concerns when conducting NbS assessments are also highlighted. In summary, the conceptual framework proposed in this study can be used to assess NbS performance and determine whether NbS interventions align with the NbS standard criteria provided by IUCN, utilizing the introduced assessment tools.

Climate change is increasing the vulnerability of communities to drought, with rural communities in developing countries being affected the most. The study assessed drought vulnerability in south western Zimbabwe based on the Analytic Hierarchy Process (AHP) supported by Geographic Information System (GIS) and remote sensing techniques. An empirical research design based on verifiable evidence of drought vulnerability was adopted. GIS and remote sensing data were used to execute the multi-criteria AHP for the determination of drought vulnerability. ArcMap 10.8 software was used for the analysis of drought influencing factors and carrying out the weighted overlay. Results indicate that almost the whole of south western Zimbabwe is prone to droughts with only 0.6 % of the area being comparatively better. It was also noted that the majority of the population are exposed to high and extreme risk of droughts as they are settled in extreme and high drought risk zones. The study recommends implementation of resilience building interventions from an informed dimension where specific resilience building initiatives are implemented in appropriate environments for high returns. This can sustain the communities in the face of increasing drought risk due to climate change in line with the aspirations of the universal sustainable development goals and the country's vision of attaining an upper middle-income society by 2030. A framework for creating drought resilience was developed to ensure that development stakeholders cooperate to build drought resilient communities in tropical regions with drought challenges like Zimbabwe and the rest of Southern Africa.

This article explores the broad area of rangatahi Māori climate activism. As a research team made up of academics, rangatahi and rangatahi Māori activists, this perspective piece discusses the importance of whakapapa, belonging and connections to the environment as a foreground to climate activism. While we highlight the lack of academic research focussed on rangatahi Māori climate activism, we show that there is a plethora of activity happening through digital and social media which provides a rich space for sharing innovative ideas for a just future in which nature is centered. We suggest that there are many commonalities between the current articulations of Nature-Based Solutions and rangatahi Māori activism and that greater dialogue between these spaces is vital for any solutions being offered for an environmentally just future for Aotearoa.

Livestock production in Mwenezi District (MD) has become more susceptible to effects of climatic variability and change which undermines developmental gains from livestock value chain. Climate change impacts are increasing the intensity of livestock poverty and deaths across all forms of livestock. The study examined livestock production interventions implemented to reduce livestock poverty deaths in MD. Descriptive research design which utilizes both qualitative and quantitative paradigms was used to accurately and systematically describe the phenomenon. A household survey questionnaire was administered to sampled households in MD wards 4 and 10 while interviews were conducted with purposively selected key informants from the department Agriculture Technical and Extension Services (AGRITEX), Veterinary Services Department, Rural District Council, CARE and District Development Coordinator's Office. Various interventions including construction of improved livestock structures, availing of safe drinking water for livestock, livestock feed formulation have been initiated to reduce and contain livestock poverty deaths. The study recommends that development actors should initiate more interventions to boost livestock production sector since it is the most suitable intervention in relation to climate and weather conditions experienced in MD. The research offers insights to address the complex interplay between climate change, livestock farming, poverty and resilience building. Results inform future researchers while guiding policy makers working in similar contexts on how best to support vulnerable communities. Findings lessen the burden to achieve Sustainable Development Goals namely no poverty, zero hunger amongst others. The study enlightened farmers on how to implement drought mitigation and adaptation techniques during drought periods.

Nature-based solutions (NBS) have emerged as crucial and promising interventions to realize resilient, sustainable, and climate-adaptive cities. One key approach is integrating them into real estate development. While real estate-related NBS – like green roofs, walls, car parks and pocket parks – are applauded for their benefits in terms of quality of life and real estate value, they are also at the core of justice concerns. If left unaddressed, NBS can lead to green gentrification and spark a wider justice discussion on distributional, procedural, recognition, and ecological justice. In this paper, we explore how to shift from a ‘win-lose’ to a ‘just’ implementation of NBS in real estate, by collecting qualitative data from Dutch real estate and NBS practitioners on projects that aimed for NBS integration into real estate while attending to (dimensions of) justice. We identify fifteen enablers that support ‘just’ real estate-related NBS, clustered under four themes (government support, knowledge, community engagement and organizational management). Based on these findings, we propose managerial implications for ‘just’ NBS integration in real estate and avenues for further NBS research.

Nature-based Solutions (NbS) can be applied to alleviate negative human impacts on ecosystems and promote the general health or well-being of the environment. Human-induced activities, including installation of NbS, are governed by legislative requirements (e.g. Environmental Impact Assessments (EIA)), especially when such activities occur in Marine Protected Areas (MPA's). A correct and thorough description of the legislative framework governing the application and development of NbS is therefore essential. The Drivers-Activities-Pressures-State change-Impacts (on human Welfare)-Responses (using Measures) or DAPSI(W)R(M) framework is valuable when environmental assessment procedures include a NbS, as well as when policy and industry require guidance for the practical application of a NbS concept. In this study, we applied the DAPSI(W)R(M) framework to the Coastbusters approach, in which mussel beds (Mytilus edulis) and tubeworm aggregations (Lanice conchilega) are installed in the Belgian part of the North Sea with the aim of improving coastal resilience and maritime infrastructure works. Within the context of the Coastbusters approach, the various elements of the DAPSI(W)R(M) framework were elucidated. Coastal defense is a driver, with activities including the integration of coastal infrastructure and aquaculture practices. Pressures related to these activities on benthic habitats were described using the MarESA sensitivity approach. State change assessments were performed based on the various marine regulations (e.g. Marine Strategy Framework Directive, Habitat Directive, Water Framework Directive) which together outline a precise set of criteria and indicators designed to assess the sustainability and health of ecosystems. The present study provides a detailed framework for the environmental evaluation of seaward NbS, from state changes to impacts on human welfare. Three quantitative estimations of ecosystem service indicators (coastal protection, carbon retention and water quality (N) regulation) were used, with the indicators quantified by in-situ measurements and data from literature. Subsequently, the 10-tenets approach for taking measures (e.g. use of biodegradable material, local species, etc.) was used to develop responses that facilitate the optimal implementation of NbS. The approach outlined in this study can be used as a guide for stakeholders as they move through the environmental evaluation processes that are required for successful development of a seaward NbS. Our results underscore the importance of a favorable institutional environment for NbS and suggest that public acceptance and stakeholder involvement play a crucial role in successful implementation. This study contributes to the understanding and operationalization of Nature-based Solutions in coastal management.

Nature-Based Solutions (NBS) are growing in popularity as approaches for, among others, the reduction of hydro-meteorological risks. However, their uptake is still slow despite the recognition of their role in enabling a smarter, more systemic, and faster adaptation to climate change. Uncertainties regarding the valuation and subsequent economic feasibility of NBS are deemed to be a substantial barrier to their uptake. The monetary valuation of the non-tangible benefits of NBS (e.g., increased recreation and enhanced biodiversity) is seen as a plausible strategy to get closer to providing a holistic assessment. However, the quantification of these non-tangible benefits is often not integrated into economic assessments of NBS, partly as methods that can be replicated across sites have been lacking. This situation risks leading to inconsistent and/or biased valuations, which may negatively influence or delay the prioritization of NBS. Thus, our study aims to collect primary data on the non-tangible benefits of NBS across different European study sites and to identify patterns in how the different types and contexts of NBS influence people's valuation. We applied a contingent valuation survey to six different peri‑urban NBS study sites, where the focus is on the reduction of hydro-meteorological risks. The target of the survey was the general public, and we used willingness-to-pay questions to quantify the value given by the respondents to the NBS. Our results highlighted that people value the multiple benefits of NBS, and positively react to implementations improving nature across all sites. Moreover, similar variables seem to influence the value attributed to NBS across sites, with income and personal preferences ranking highly among them. These insights indicate that decision-makers and NBS-planners can learn more broadly from past experiences from a variety of (cultural) contexts, which can assist in delivering more targeted and multi-functional NBS.

However, their uptake is still slow despite the recognition of their role in enabling a smarter, more systemic, and faster adaptation to climate change. Uncertainties regarding the valuation and subsequent economic feasibility of NBS are deemed to be a substantial barrier to their uptake. The monetary valuation of the non-tangible benefits of NBS (e.g., increased recreation and enhanced biodiversity) is seen as a plausible strategy to get closer to providing a holistic assessment. However, the quantification of these non-tangible benefits is often not integrated into economic assessments of NBS, partly as methods that can be replicated across sites have been lacking. This situation risks leading to inconsistent and/or biased valuations, which may negatively influence or delay the prioritization of NBS. Thus, our study aims to collect primary data on the non-tangible benefits of NBS across different European study sites and to identify patterns in how the different types and contexts of NBS influence people's valuation. We applied a contingent valuation survey to six different peri‑urban NBS study sites, where the focus is on the reduction of hydro-meteorological risks. The target of the survey was the general public, and we used willingness-to-pay questions to quantify the value given by the respondents to the NBS. Our results highlighted that people value the multiple benefits of NBS, and positively react to implementations improving nature across all sites. Moreover, similar variables seem to influence the value attributed to NBS across sites, with income and personal preferences ranking highly among them. These insights indicate that decision-makers and NBS-planners can learn more broadly from past experiences from a variety of (cultural) contexts, which can assist in delivering more targeted and multi-functional NBS.</p></div>","PeriodicalId":100945,"journal":{"name":"Nature-Based Solutions","volume":"6 ","pages":"Article 100146"},"PeriodicalIF":0.0,"publicationDate":"2024-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772411524000375/pdfft?md5=a7e5344d879a878c8a7c78e0c1e7422b&pid=1-s2.0-S2772411524000375-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141541320","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}

Estuaries worldwide are of substantial ecological value due to the presence of various gradients, such as salinity. Preserving the natural value of estuaries is vital for meeting the climate stabilization goals of the Paris Agreement. Recognizing nature as a stakeholder is imperative, given the surpassing value of ecosystem services over global gross domestic product. Quantifying the current ecological state and future ecological shifts faces challenges, including variable dependencies, spatial-temporal disparities, and the limitations in available information. This study introduces EMMA (Ecotope-Map Maker for Abiotics), a method for quantifying the effects of human interventions or climate change scenarios on estuarine ecosystems by linking abiotic characteristics derived from a hydrodynamic model to ecotopes. The Western Scheldt, an estuary connecting the Scheldt river to the North Sea in the Netherlands, serves as a case study. The method successfully reproduced an existing ecotope-map, which is dependent on real-time data such as aerial photographs. The developed method not only proves applicable in assessing the current ecological state and future ecological shifts for hypothetical scenarios but also demonstrates utility in predicting future situations, providing valuable insights for decision-makers in estuarine ecosystem management and contributing to climate and environmental preservation goals.

The culturally diverse region of Moananui Oceania, is where many of the world's nations that are most impacted by climate change are located, including Samoa. Nature-based solutions (NbS) offer significant potential for effective climate change adaptation and are increasingly being explored and utilized in the region both in terms of (re)exploring traditional human designed living-systems created over connected land and oceanscapes, and in relation to contemporary NbS strategies. To explore nature-based adaptation agendas that link closely to Indigenous ecological knowledge and understandings of wellbeing, and that can enhance cultural connections to NbS in an urban climate change adaptation context, the Nature-based Urban design for Wellbeing and Adaptation in Oceania (NUWAO) Vaisigano Project in Samoa was conceived. The project examines and draws upon contemporary and traditional relationships between human settlements and nature in Samoa, as a means to advocate for regenerative urban environments that enhance entwined socio-ecological wellbeing and resilience as a climate change adaptation measure. We conducted a series of household interviews along a ridge-to-reef transect in the Vaisigano Catchment and then conducted fa'afaletui focus groups to ascertain community understandings and priorities related to NbS for climate change adaptation. Findings include that there is great potential in combining local Indigenous knowledges and worldviews with contemporary nature-based approaches to create culturally effective, just, and resilient climate change adaptation measures in Samoa, and in wider Moananui Oceania.
