Climate change, environmental hazards, and natural disasters present unprecedented challenges. Communities across the globe need tailored tools and solutions that improve their unique capacity to mitigate, respond, and rebuild from devastating events and maintain life with quality. Their success relies on the initiative, collaboration, and input from and with communities and experts across disciplines – including the technical and social sciences. These tools and solutions may be technology driven (e.g., low-cost sensor deployment to assess air and water quality) or policy driven (e.g., climate action plans) – they are by necessity iterative, interconnected, and evolving –, but ultimately reside in community priorities.
Facing escalating climate issues, Nature-based Solutions (NbS) have emerged as a holistic approach addressing climate change mitigation and adaptation, steering towards a sustainable future. NbS resonate with global frameworks like the IPCC Climate Change and Land Report, the Paris Agreement, and the European Green Deal’s climate-neutral vision. These initiatives not only address environmental challenges but also enhance social and economic resilience. Integrating community-led science with NbS leads to innovative practices, merging local knowledge and scientific inquiry, and fostering sustainable community livelihoods.
This session aims to showcase how community-led science efforts and NbS can catalyze transformative change and resilience against climate and environmental crises. This interdisciplinary forum will bring together community leaders, scientists, technology developers, and policy professionals and drive discussion on how to best i) identify regional and local environmental priorities, ii) inclusively equip communities with diverse socioeconomic backgrounds with science-based tools, iii) address the implementation of NbS and related tools in varied regional settings, and iv) assess NbS and integrated approaches’ role in climate change mitigation and adaptation.

Cities are major contributors to climate change through greenhouse gas emissions, notwithstanding other sources of pollution, conditioning planet health and citizens wellbeing. The increase in urban growth and urbanization results in an expansion of urban hazards - including water scarcity, air pollution and other environmental issues. Therefore, to respond to the need for new urban development, it is necessary to introduce a new systems-based approach able not only to maintain the existing environmental indicators, but to guarantee their improvement. 

To address this complexity, in this work we explore Regenerative Design (RD) definition, scale and proprieties to rethink the ecological challenges we face in a holistic and systematic manner.  Regenerative Design approach, in this study, aspires to demonstrate that order to achieve net-positive outcomes and address social and ecological issues, it is necessary to move beyond the only intention of environmental harm mitigation. The regenerative design process leads to design processes that utilize the insights and relationships of ecological systems of the place as the basis for projects in which human actions positively contribute to the self-healing properties of nature. Therefore, an integration of nature-inspired solutions throughout the design process is required.

This study evidence that a transformative shift towards regenerative design requires not only a change in way of thinking and practice, but also in worldviews and values. It starts with the awareness the way we approach analysis of a design process might not be regenerative. Therefore, there is need for systems change to tackle root causes of degeneration, where the context and the place-based design decisions are of crucial importance.

Urban Green Spaces (UGS) serve as crucial ecological and social assets in urban areas, significantly contributing to the sustainability and well-being of city life. This research delves into the assessment of UGS quality in Delhi, aligning with the 2030 Agenda for Sustainable Development, specifically Sustainable Development Goal (SDG) 11 - Sustainable Cities and Communities. This study emphasizes the importance of UGS as Nature-Based Solutions. Previous studies have explored diverse attributes to evaluate UGS quality, incorporating elements like percentage green, built-up density, and proximity to green spaces. However, these studies often focused on specific aspects associated with any of the three important elements: impervious areas, vegetation, and population. This approach leaves a gap in comprehensively assessing the overall status of UGS, even if one element is taken out of the picture. To address these limitations, this study adopts a holistic approach by considering nine key attributes, including Proportional Population, Impermeable Surface Area, Proportional Impermeable Surface Area, Per-capita Green Index, Buffer Area around UGS, Normalized Difference Vegetation Index, Soil Adjusted Vegetation Index, Green Space Coverage, and Proportional Green, to offer a quantitative measure of UGS quality in Delhi. The Urban Green Spaces Assessment Index (UGSAI), derived from these attributes, provides a comprehensive understanding of UGS in the city, ranging from 0 to 100. The UGSAI categories, divided into five - Very Low (<20), Low (20-35), Moderate (35-50), High (50-65), and Very High (>65), were carefully determined for effective representation, revealing significant variations among wards. A higher UGSAI value indicates better green space conditions, signifying areas that are more accessible, sufficient to cater to the needs of the population of the particular ward, and have higher-quality green spaces. UGSAI values for the wards ranged from the lowest at 6.10 to the highest at 76.32. The study unveils that over 60% of wards fall into the Very Low to Low category, 33% in Moderate, and only 5% in the High to Very High category of UGSAI. Additionally, the correlation of the nine attributes used was tested with UGSAI, and the results indicated strong correlations between UGSAI and Green Coverage, SAVI, and NDVI (r=0.90), along with a strong negative correlation with Impermeable Surface Area (r = -0.87), revealing the attributes that are crucial for improving the UGSAI of a ward. This underscores the need for local-level improvements in management and an increase in UGS, especially in the identified critical areas. This research, grounded in Nature-Based Solutions, provides valuable insights for decision-makers, promoting informed choices that foster resilient and sustainable urban ecosystems. Moreover, the robust methodology and effectiveness of the Urban Green Spaces Assessment Index (UGSAI) presented in this study underscore its potential as a valuable tool applicable beyond Delhi, offering a comprehensive framework for assessing UGS in diverse urban contexts and guiding sustainable development initiatives.

Urban agriculture is a nature-based solution to increase the economic, social and environmental sustainability of cities and city food systems. However, sustainability is difficult to measure, and there is therefore discussion about whether urban agriculture really contributes positively to sustainability. Monitoring data could provide evidence of the impacts of urban agriculture and help inform decision makers about whether and where to prioritise different forms of urban agriculture above competing interests.

Using case examples from five European cities, we identified the challenges involved in monitoring urban agriculture, from selecting indicators and gathering data, to using the results. We found large differences in approach in terms of what topics to monitor and who was responsible, who gathered the data and when, what data was recorded and how they were stored, and how findings were disseminated or published. Based on these experiences, we recommend stronger involvement of existing interest groups and educational institutions in monitoring urban agriculture, and promotion of convenient tools for data collection by citizen science and for long-term data storage.

The political, economic, social, technological, environmental, and legal (PESTEL) dimensions in a local community shape the adoption of specific nature-based solutions (NbS) to improve water ecosystem services. This study provides crucial insights on integrating NbS tailored to smallholder indigenous and peasant communities in four central Ecuadorian provinces, covering 43.2% of the Andean region. These communities are located in the páramo, a highly valued ecosystem for water-related ecosystem services. However, they face high levels of poverty and malnutrition. Combining a participatory multi-stakeholder approach with a literature review, we gathered insights into PESTEL dimensions impacting páramo ecosystem services. A bibliometric and decision tree analysis was then employed to reveal NbS aligned with PESTEL dimensions in these communities. As a result, limited financial support, urban-centric environmental investment, and insufficient acknowledgment of water-related ecosystem services significantly impact the health of páramo ecosystems from economic and political dimensions, respectively. In the environmental dimension, the overexploitation of this ecosystem, driven by high soil carbon storage combined with superior water quality and the high vulnerability to climate change, contributes to the decline of the páramo remnants. Social, legal, and technological dimensions involve community dissatisfaction and resistance to conservation, lack of sustainable land and water management, and the mismatch between technology, the economy, and data availability. These impacts on páramo ecosystem services occur directly through water purification, regulating soil formation, and maintaining populations and habitats. Indirectly, they affect the provision of water for drinking and non-drinking purposes, fishing and aquaculture, recreation, and spiritual and symbolic appreciation. To enhance water-related ecosystem services, we propose the establishment of artificial floating islands such as NbS. These islands are seen as an innovative restoration method with multiple benefits, such as the need for only limited financial support, the engagement of local communities, the lack of land requirements for implementation, and the use of indigenous community knowledge of appropriate plant species for water treatment, which can even generate additional income. Passive restoration complements this by removing disturbances in the páramo, allowing natural regeneration in basins by state-led land purchase initiatives to ensure the protection by Ecuadorian conservation laws. Our study offers decision-makers a practical approach to secure ecosystem services for vulnerable populations, critically assessing alternatives based on the dimensions and needs of these communities.

This study compares and analyzes the impact of land use changes on ecosystem services and ecological security in different ecological backgrounds in Stockholm and Panjin. Using Morphological Spatial Pattern Analysis (MSPA), Analytic Hierarchy Process, and Circuit Theory, the dynamic changes in ecosystem services and ecological security patterns are assessed in these two regions. Based on the characteristics and land use changes from 2000 to 2020, four scenarios for 2050 are simulated using the PLUS model: Business-as-Usual (BAU), Priority Urban Development (PUD), Priority Ecological Protection (PEP), and Balanced Urban-Ecological Development.The results show that in Panjin, the growth rate of construction land was 21.49% from 2000 to 2020, and when this probability was applied to the transfer probability of Priority Urban Development in the Stockholm region, there was a significant change in the ecological security pattern. In contrast, in Stockholm County, the correlation between the change rates of all land use types and other indicators was weak, suggesting limited influence of these factors on land use changes. However, in Panjin, there was a strong positive correlation between the change rates of construction land, unused land, and population and GDP. This implies that in regions with lower economic levels, there is a higher dependence on ecosystem services and ecological security patterns compared to higher economic regions.Observations reveal an increase in forest and grassland area in Panjin City. However, the distribution of high-value ecological source areas is not concentrated enough and exhibits a high rate of change. In contrast, the Stockholm region has maintained a stable pattern of ecological source areas over the past 20 years. The Stockholm region has developed a relatively reasonable ecological security pattern, which is the result of continuous ecological protection and planning efforts over many years.

The integration of Eco-DRR practices in geopark management is a promising method to strengthen community resilience. In the context of the Caota dunes geopark, the level of engagement and support from local residents could significantly contribute to the effectiveness of Eco-DRR approaches through fostering awareness, strengthening the local economy, enhancing ecosystem services, promoting sustainable resource use and facilitating the adoption of resilient livelihood practices. However, it is essential to first understand the needs of the community before implementing these strategies. This study aimed to identify critical factors by exploring community needs and challenges through interviews and focus groups to identify pathways for an inclusive and community-centered approach to the geopark's implementation and conserve the essential functions of the dune landscape.  

Capacity building has contributed to an increased sense of responsibility and commitment from the local community. Nevertheless, insights from local community members highlighted the urgent need for economic benefits and future stability for the geopark through more defined development plans and increased community involvement. This study highlights the importance of incorporating community insights early in the development process  and promote bottom-up approaches, providing greater opportunities for active participation in geopark planning, management, and monitoring.

The coastal region of Bangladesh is greatly impacted by high soil and water salinity levels, worsened by tropical cyclones and rising sea levels. Understanding the extent of salinity and its challenges is vital for sustainable agriculture and safe drinking water. This study employed both quantitative methods, focusing on soil and water parameters, as well as qualitative approaches such as focus group discussions (FGDs) and key informant interviews (KIIs). The objectives of this research were to assess soil and water salinity, and soil nutrient content, and to investigate adaptive practices and challenges in agriculture and drinking water management in six sub-districts in the southwestern coastal region of Bangladesh. Qualitative information obtained from 18 FGDs and 16 KIIs was assessed by thematic and content analysis to evaluate the community-based adaptive techniques and challenges in sustainable agriculture and water management in the salinization-affected region. Using a one-way ANOVA and post hoc Tukey tests, the soil and water parameters of the collected 165 soil samples (croplands), and 132 water samples (ponds and canals) were analyzed to assess the soil nutrients (nitrogen, phosphorus, and potassium) and soil and water salinity in six sub-districts.

The soil nitrogen, phosphorus, and potassium contents exhibited significant variations, whereas there was no notable difference in soil salinity content across the studied sub-districts. Upon examination of pond water salinity levels, significant variations were observed among the six sub-districts. The salinity levels (ds cm-1) in pond water ranged between 13 and 14 ds cm-1 in these sub-districts. Among them, Shyamnagar recorded the highest level of pond water salinity (13.99), followed by Assasuni (13.96), Dacope (13.91), Koyra (13.58), Morrelganj (13.33), and Mongla (13.19) sub-districts. Pairwise comparisons of salinity levels in pond and canal water show that the salinity level in most water samples varied significantly among sub-districts.

Respondents in FGDs and KIIs consistently identified salinity as a major challenge in agriculture and drinking water in the studied sub-districts. Additionally, climate-induced stresses, such as untimely precipitation, and pest outbreaks during droughts were recognized as significant issues impacting sustainable agriculture. In terms of adaptive practices, this research emphasizes the feasibility of rainwater harvesting as an effective technique for managing drinking water and mitigating water and soil salinity. This approach offers a viable solution for addressing water scarcity and salinity issues in the coastal region. One notable finding in agriculture from the research is the positive impact of organic fertilizer (vermicompost) in reducing soil salinity levels. This finding highlights the potential of utilizing organic fertilizer as a nature-based solution to mitigate salinity in the affected regions of Bangladesh and globally. By adopting such adaptive strategies, the region can promote resilient agricultural systems and ensure sustainable water management.

In summary, the study highlights the prevalence of soil and water salinity in the coastal region of Bangladesh and the associated challenges it poses for agriculture and drinking water management. The research emphasizes the significance of adaptive practices, specifically rainwater harvesting and organic fertilizer, as a practical solution to address water scarcity and salinity issues in the region.

The Coastal Bend Region (CBR) of Texas is vulnerable to acute and chronic environmental stressors stemming from natural and industrial sources, including flooding and erosion from high tides, storm surge events, and ship traffic, as well as higher levels of air and water pollution due to expansion of nearby industrial operations. Communities in the CBR are diverse, spanning a range of sizes, demographics, and geographies, and have varying levels of exposure, vulnerability, and capacity to respond and adapt to the cumulative threats posed by climate change and industrial expansion. Currently, residents of the CBR are engaging in a variety of community organizing and advocacy efforts, including through existing and newly established community-based organizations. These organizations span a range of experience levels and capacities in interfacing with local decision-makers and engaging in collective action to address environmental threats, but all have expressed a need for more comprehensive data about environmental and industrial conditions to advocate for and make informed decisions about risk reduction strategies that mitigate negative impacts on air, water, and land resources.

Here, we discuss an ongoing research program to examine how smart and connected technologies can be integrated into regional communication and advocacy networks to increase awareness of natural and anthropogenic hazards and build community adaptive capacity equitably among the diverse residents in the CBR. We first present the results of a year-long planning study conducted in partnership with one CBR community to (1) evaluate the structure and function of the local communication, information-sharing, and policy-making networks and (2) co-develop a real-time, wireless sensor network and community dashboard to monitor environmental conditions. This study led to the formation of interdisciplinary, academic-civic partnerships that centered community needs in the design and implementation of the research objectives. We then discuss challenges and opportunities in expanding this work to the regional scale to engage a broader diversity of CBR residents using a bottom-up, participatory design approach, with the goal of supporting frontline communities as they advocate for more sustainable and equitable policies for hazard management.

This study addresses the urgency to re-strategize our local action to prevent future climatic risk as a result of extreme weather events, urbanization, anthropogenic activities in a changing climate. While progress has been made in implementing the Sendai Framework for Disaster Risk Reduction since its adoption in 2015, no country is on track to achieve the outcome and goal by 2030. Malaysia is not an exception. A holistic approach to multi-scale disaster risk reduction and climate resilience is critically needed to examine new prospective agenda for accelerated action. This study provides a new insight into galvanizing technological advancement, multi-tier partnership and community-led approach to entail more coordinated and programmatic action towards translating resilience thinking approach into risk-informed decision-making. Equipping cities and communities with knowledge and capabilities to manage complexity of risks is a step forward to re-build a resilient society and rejuvenate resilience thinking. UNDRR’s global reports indicated that by providing a 24-hour early warning can reduce the resulting damage by 30%. Therefore, investing in the development of people-centered, end-to-end, multi-hazard early warning system (EWS) is highly regarded to support the 2027’s Early Warning for All agenda. This study highlights smart partnership into co-designing, co-developing, and co-implementing an impact-based EWS for geological risk in Jerai Geopark (Yan, Kedah), towards rejuvenating local resilience strategy through the development of DRR Yan Model and Resilience Living Lab in a national geological heritage area dominated by tourism industry. The key for successful community-led disaster risk reduction (CLDRR) lies in maintaining interest in resilience culture and motivation for local agenda at the grassroot level. We also demonstrate community-led DRR program with a unique localization strategy that addresses dam-related disaster risk. This study acknowledged that 40% of large dams in Malaysia are aging, necessitating new approaches to dam safety. Moreover, regional benchmarking for technological-based sociotechnical systems enabled by collaborative foresight and disaster informatics are a way forward to assess future emerging hazards, systemic risk, and compounding disaster. With good risk governance, evidence-based risk investment, and risk-informed decision making, as supported by all-of-society approach particularly in advancing a new partnership model for the public-private-academia-civil society, this study reports current demands for de-risk strategies that shall be systematically incorporated into decision-making, governance, and investments. The development of new strategies, actions, and initiatives are mutually explored towards inculcating targeted investments related to systemic risk reduction, and mainstreaming urban development planning of unattended risks should be made based on science, coupled by the Local, Traditional and Indigenous Knowledge (LTIK) approach. The de-risk investment efforts often jeopardize by a series of sudden, large-scale geological-induced disaster, resulting into the prolonged economic impacts continues to escalate and underscores the multi-scale investment for DRR agenda at a local level. By adopting a transdisciplinary approach to DRR and forward-looking risk-informed approach, this vulnerable region can further develop its resilience capacity to tackle complex challenges of climate risks. As a conclusion, risk-informed pathway in development planning, and a paradigm shift, can contribute towards promoting equitable and sustainable resilience in geologically risk sensitive regions.

Professional societies can play important roles in society's climate change response. Sitting at the junction of scientific innovation, policy advocacy, and community engagement, professional societies are uniquely positioned to bridge the gap between principal investigators (PIs), governments, and local communities. As non-governmental actors, these groups streamline the transfer of research into actionable strategies by facilitating knowledge exchange, standardizing methodologies, and fostering multi-stakeholder collaborations.

This presentation will outline how professional societies can amplify the reach and relevance of scientific endeavors and help ensure that community priorities are at the forefront of environmental policies and practices. It will argue for their enhanced involvement in driving interdisciplinary approaches, advocating for inclusive and informed policy-making, and empowering communities through accessible, science-based solutions. The session aims to inspire a cohesive dialogue among community leaders, scientists, and policymakers, highlighting the necessity of a united front to effectively address the pressing environmental challenges of our times. Lastly, the talk will highlight the joint Optica-AGU Global Environmental Measurement and Monitoring Initiative.

The impacts of increasing water scarcity as a consequence of climate change determine an urgent demand
for enhanced management of water resources. The construction of new artificial reservoirs to expand
water storage capacity represents a pivotal strategy to address these pressing concerns and fulfil the
community&#39;s needs for drinking water, irrigation, energy generation, and flood risk mitigation. The
selection of sites for new reservoirs can be merely based on topographic and hydrologic assessments.
However, the identification of optimal locations requires a comprehensive evaluation that considers a
multitude of often-competing factors that encompass bio-physical, socio-economic, regulatory, and
environmental aspects. The involvement of communities and citizens in the initial stages of the decision-
making process is crucial. This study introduces a methodology based on multi-criteria decision making
(MCDM), to identify optimal reservoir locations, simultaneously addressing all the aforementioned aspects
through community engagement. This methodology employs an automated algorithm to analyse a large
pool of potential sites, through a Digital Elevation Model (DEM) integrated with hydrologic simulations. For
each site the algorithm optimizes the location and orientation of the dam and calculate the geometrical
characteristics, such as the dam length, dam volume and the water storage volume. In a subsequent step, a
MCDM analysis is conducted to rank the sites based on quantitative selection criteria established through a
comprehensive territorial analysis and hydrological modelling. These criteria include geometric and
morphological aspects (e.g., reservoir volume), hydrological indicators (e.g., water balance, flood
mitigation), anthropization (e.g., population density, infrastructures), landscape, archaeological heritage,
ecology, environmental components, and potential natural hazards. To foster community engagement, we
developed a web-based survey platform that enables the collection of diverse perspectives from various
stakeholders, communities and citizens, allowing them to express their opinions on the relative importance
of each individual criterion. The application of this methodology is demonstrated through a case study in
the Arno river basin, Italy, showcasing its effectiveness in identifying the most suitable reservoir locations
while targeting the highest environmental preservation and community well-being.

Citizen science is important for community-led science. However, the knowledge and costs required to configure and manage servers for data management in such community-led projects are major barriers to the adoption of citizen science-based approaches at a larger scale. At the same time, the centralisation of communities’ data onto project servers (whether rented in « the could » or on-premise) also poses questions regarding data sovereignty true community ownership of citizen science projects. (Who owns the data? Who has the power to give or revoke access to it? How will data be accessible once the principal investigators and funding are gone?)

Distributed databases, where data is stored directly on users’ devices and shared in a peer-to-peer network, can address some of these issues by bypassing the need to rely on a centralised server for user authentication and data storage and transmission. While this approach offer solutions to some long-standing challenges of centralised approaches to data collection, distributed databases also bring their own limitations. This presentation will discuss three major questions and paradigm shifts related to the adoption of distributed databases for citizen science, namely authorisation, discovery and accessibility. Approaches for addressing these in the context of community-led participatory projects will be discussed, and examples of using Constellation distributed database software for case studies in citizen science and data sharing will be provided.

In the event of disasters such as droughts, floods, and landslides, social sectors including housing, education, and social protection are the most affected. Here, we present a project that incorporates the school system as a vulnerable sector to water insecurity and a tool to promote resilience. In this sense, we adopt the concept of water security defined by the United Nations (UN), including the availability of water to support socioeconomic development, the preservation of aquatic ecosystems, and the ability to withstand a reasonable amount of risk from floods and droughts. Planning for the supply and use of water at the national level should be based on the four elements of water security. This project is contextualized at the Brazilian National Observatory for Adaptive Water Security and Management (ONSEAdapta) (https://onseadapta.org/en/elementor-642/). Given the importance of schools, the objective of this project is to propose a conceptual framework to incorporate school resilience as a response to water-related disasters and adaptive management. The proposed methodology is divided into two approaches. First, a top-down approach is proposed to collect data from the annual school census of Brazilian schools that is provided at school level by the Anisio Teixeira National Institute of Educational Research and Studies (INEP) and water security data from the National Water and Sanitation Agency of Brazil (ANA). Second, a bottom-up approach is proposed to survey educators and members of the school community to depict how water security is incorporated into schools, what initiatives promote the participation of school and society, and the main implications for reducing disaster risk, building capacity, and increasing disaster resilience. In Brazil, according to the 2022 school census, there were 184,331 schools that accommodated 22% of the Brazilian population (~47 million students). To propose the concept of school resilience as a dimension of water security, we located and diagnosed the number of schools that are in water insecurity by combining the Brazilian water security index (ISH) with the georeferenced map of Brazilian schools. Using the ISH that combines human, ecosystemic, economic, and resilience dimensions, we identified that 11.93, 14.40, 16.04 million students are under minimum to low, medium, and high to maximum water security, respectively. This analysis unveils that almost 28% of Brazilian students are below a low level of water security. These students come from preschool, elementary and secondary education in rural and urban areas. We conceptualize the assessment of school resilience using a comprehensive framework that considers infrastructure, level of water insecurity, impacts on school, emergency preparedness, and community involvement. To foster community involvement and scientific contributions, the next step is the creation of an online platform to promote citizen science, collect data, and engage with educators. By fostering participatory citizenship education in schools, this project aims to create a resilient and well-informed community capable of mitigating the impact of disasters and contributing to general water security and adaptive management.

The integration of Nature-Based Solutions (NBS) in urban stormwater management holds transformative potential, promising enhanced adaptive capacities and numerous benefits for community well-being. Acknowledging the localized nature of NBS projects, primarily managed at the community level, this study delves into the prospects of integrating community governance into the planning, implementation, and success of NBS initiatives, especially in the context of urban flooding.

With the overarching goal of identifying strategic leverage points for enhancing community governance structures in urban NBS implementation, the research employs a System Dynamics modeling approach, to investigate the impact of decentralizing decision-making authority to local communities on the scalability and sustainability of NBS in urban stormwater management. The analysis probes dynamic interactions and causal relationships among decentralized decision-making structures and critical variables such as community participation, institutional frameworks, and resource allocation that define community governance. Emphasizing a comprehensive understanding of feedback mechanisms, the study seeks to unravel processes shaping the adaptive capacities of NBS over time, particularly within the intricate context of adapting to the impacts of climate change.

The study strives to provide insights into the mechanisms governing scalable integration, underscoring the vital role of community involvement and participatory governance in Nature-based flood solutions and in doing so, offering a crucial foundation for fostering sustainable and resilient urban development amid the escalating challenges posed by urban flooding and climate change.

Climate change is expected to affect the frequency, magnitude and seasonality of various precipitation-related hazards, including flooding as one of the costliest hazards in Europe. As natural hazards have a significant impact on infrastructure, human lives, and habitats, it is clear that adaptation measures aimed at both prevention and mitigation need to be considered to address climate change. Green (referred to as Nature-based) measures are currently being promoted by the European Union, but in some planning contexts these measures may not be fully capable of coping with predicted future climate hazards, especially in the case of extreme events. Furthermore, the implementation of such measures is often met with resistance from planning departments and decision makers due to institutional dependencies created by the use of grey infrastructure measures in the past. In addition, scepticism about the effectiveness of green measures goes hand in hand with a preference for grey measures. Hybrid measures do have a prevailing green visual look, they can fulfil some ecosystem services, but they require substantial technical equipment for implementation and may present a feasible complementary measure in planning context with limited space or already existing infrastructure. These solutions therefore combine parts of grey and green measures and present an alternative that can reflect the diversity of environmental conditions.

This study evaluated the effectiveness of selected green (e.g. urban trees, rain gardens), grey (e.g. drywells, permeable sidewalks) and hybrid (e.g. green roofs, stormwater tree tranches) measures on flood risk using hydrological modelling with the HEC-HMS software. This study was carried out in order to define the most effective and suitable flood protection measures for the selected case study, the Glinšcica river basin in the municipality of Ljubljana in Slovenia. Based on the hydrological modelling performed, rain gardens were found to be the most effective measure in terms of reducing peak runoff and runoff volume for the Glinšcica river model. Both green roofs and stormwwater cisterns also showed relatively good results compared to the other measures. The hydrological study was combined with a public perception survey in which we investigated the acceptance, feasibility and effectiveness from the perspective of the Slovenian public. Therefore, we were interested in whether there are differences in the perception of the selected green, grey and hybrid flood risk management measures. We were also interested in which of the contextual (e.g., flood exposure and experience) and compositional (e.g., socio-demographics) factors influence public perception of the acceptability, feasibility, and effectiveness of these measures.

Hanoi City has experienced a remarkable transformation due to implementing Hanoi's Master Plan 2030, which brought forth numerous challenges, notably in preserving urban green space (UGS). The objectives of this work are to (1) explore the changes in UGS distribution, (2) identify areas prone to heat stress by examining abnormal land surface temperature (LST) distributions in conjunction with population vulnerability, and (3) suggest solutions through an advanced UGS management platform. To investigate the UGS changes, we utilized Sentinel-2 satellite images, while the assessment of heat stress risk involved extracting LST data from the thermal infrared band of Landsat 8. Our research was concentrated on the inner region of Hanoi City, tracking UGS alterations from October 2016 to October 2018. The study's evaluation involved utilizing Google Earth images and conducting on-site research.

The results demonstrated a significant decline in woodland and shrubland, decreasing by 1.3% and 4.4%, respectively, while grass cover experienced a growth of 2.4%. Our land cover classification exhibited high accuracy, reaching 96% in 2018 and 88% in 2016. Furthermore, this work unveiled a heightened risk primarily focused in the central inner-city zones, marked by densely populous residential regions and extensive built-up environments. Given that air temperature (Ta) significantly affects human health compared to LST, our forthcoming research will incorporate a spatially continuous Ta dataset to delve deeper into studying heat stress risks. This Ta dataset will be generated through our advanced Ta estimation framework employing Machine Learning algorithms, which have demonstrated exceptional performance. Identifying the heat stress risk patterns is essential, as this draws the attention of city planners, governing bodies, and healthcare institutions.

Water problems related to floods, droughts, water quality, and supply demand require methods focused on harnessing the inherent capabilities of ecosystems to cope with water related problems and the ecosystems natural capability to address water-related challenges by leveraging this advantage on maintaining ecological balance. Although it demands more investments than traditional approaches, Nature-based Solutions (NbS) has a significant impact on promoting sustainability and its success relies on careful planning, collaboration with local communities, and adaptive management strategies. This study aims to develop an engaging and educational serious game to demonstrate how NbS can serve as a strategic approach for fostering the development of smart and resilient cities in response to the challenges posed by climate change, water-related risks, and disasters. By engaging individuals in a virtual environment, serious games can effectively communicate the consequences of various water-related decisions and encourage sustainable practices among the public. Thus, designed for a diverse audience, including students, urban planners, decision-makers, and the general public, the game utilizes realistic mathematical models to simulate climate change scenarios and extreme weather events. Yet, players can make challenging decisions in implementing NbS, like creating urban green zones, watershed management, and aquatic ecosystem restoration. The game can also incorporate real-world data for specific geographic areas, emphasizing the effectiveness of NbS in regional contexts. Finally, the game incorporates water modeling techniques, leveraging the robust capabilities of HydroPol2D and/or HyMAP models. These models enable the simulation of water runoff in two dimensions by utilizing Digital Elevation Models (DEMs), land use and rainfall data. Furthermore, collaboration with local communities and adaptive management strategies are crucial components, showcasing the importance of stakeholder engagement.

Phoenix, Arizona, a metropolis located in the Sonoran Desert in southwester USA, is expected to see major disturbances resulting from global warming, including excessive heat events1 and drought2. Urban Green Infrastructure (UGI) has the potential to help mitigate excessive heat3 yet, as water becomes increasingly scarce, efficiency in both the location and configuration of UGI is critical to maximize its positive benefits.  Well-connected UGI provides more ecosystem services and can better mitigate extreme temperatures in urban areas than poorly connected UGI 4. However, owing in part to the current and anticipated scarcity of water, the distribution and connectivity of this lifesaving resource has the potential to be unjust regarding economically vulnerable communities. The purpose of this study is to determine if there are relationships between the coverage/connectivity of Phoenix UGI and sociodemographic variables associated with vulnerability.  Using a 2010 1m landcover classification raster and the landscapemetrics R package, landscape metrics were calculated for sample plots withing areas zoned for single-family residential homes.  Vulnerability statistics were then apportioned for each plot using 2010 ASTER/CDC Social Vulnerability Index data. These variables were then examined to determine relationships between connectivity and vulnerability using Principal Component Analysis.

Between March 2016 and September 2020, the Canadian government supported a Southern African Nutritional Initiative (SANI) project in Malawi, Mozambique and Zambia to enable women of reproductive age and children under the age of 5 to  produce, access, store, preserve and process high nutrient food. We report on Zambia’s agricultural component of the project summarizing the key food production techniques used to encourage sustainable agricultural production through the use of smart agricultural practices. These  practices have the potential to allow small farm holders to adapt to climate change and offer opportunities to reduce and remove Green House Gases from these systems in order to contribute to the  Nationally Determined GHG Contributions under the Paris Agreement and meet national food security and development goals. As part of the study, in person training sessions were conducted with participants on smart agricultural practices such as the promotion of local technologies around seed bed preparation of home gardens and orchards, manuring, and the use of local products to control insects, pests and  diseases instead of chemicals. Apart from receiving training in sustainable practices, participants were also trained in food preservation and value addition to harvested produce and grains in order to increase the shelf life and usability of various food types as a way of promoting food security. Anecdotal evidence through follow up field evaluations and food preparation demonstration sessions showed that project participants were adapting  and moving towards achieving a resilient status. These and scale up issues will be discussed in this contribution.

Against the backdrop of aggravating environmental challenges, effective ecosystem services (ES) management is crucial for biodiversity conservation, livelihood support, and economic growth. Including citizens, stakeholders and societies in research is gaining popularity as a suitable tool for both informed decision-making and enhanced community resilience. Our study explores the application of knowledge co-creation methodologies to improve ES management. The French Outermost Region of La Réunion, situated in the Indian Ocean, provides an opportune setting for addressing these challenges. Community members, stakeholders, and experts were engaged in a structured, yet flexible knowledge co-creation process to jointly define the potential for cultural ecosystem services (CES) including landscape aesthetics, recreation and eco-tourism.

The collaborative process empowered the community to identify and prioritize ES through initial interviews and focus groups. This informed a participatory GIS mapping exercise, facilitating community involvement in visually representing ecosystem services and their spatial relationships. Based on this work, additional methods were employed to provide the community with information. Expert elicitation validated the community-generated knowledge, incorporating insights from local and regional professionals. In addition, geotagged photos were analysed to assess actual use of cultural ES. This approach ensured a comprehensive understanding of ecosystem interactions, including ecosystem features, capacity of ecosystems to supply ecosystem services and informed options for sustainable development.

Our results contain qualitative and quantitative assessments of CES within the study area: multiple ES maps that show the distribution of ES on spatial scale, coinciding strongly with landscape features. A high appreciation of the coastline with its scenic cliffs and rocky beaches is visible. The inland provides large potential for recreational activities and tourism, including hiking, mountain biking, horse-riding, bird watching and botany. Geotagged photo analysis added the magnitude of visitors, showing popular trails and locations.

 Yet, the application of co-creation for research proves challenging. The joint definition of research focus and the fuzziness of the approach diverge from current modes of environmental (social) sciences. Further, stakeholder engagement requires time and dedication. We find that co-creation provides aspects of community learning and empowerment. This research contributes to the discourse on knowledge co-creation as a valuable tool for addressing environmental challenges and promoting sustainable development. The insights provide a foundation for applying similar methodologies in diverse socio-ecological contexts, opening up new possibilities for community engagement in ecosystem services research.
