AN1: Soil and water conservation for sustainable land management
Description
Viable measures for sustainable land management in agricultural and forest areas can only be designed and implemented if the ecological and productive roles are well understood simultaneously with land degradation processes. This is only possible when the major processes regulating these three spheres are, measured, described and their interactions properly evaluated and modeled. Land degradation, in particular soil erosion due to water and wind, occurs in many parts of the world and it is usually associated to cropping, grazing or forest areas. Soil and water conservation measures are only viable and sustainable if local environmental and socio-economic conditions are taken into account. In this challenge, harmonizing need for increasing land productivity with soil conservation seem key, and with most of the world degraded lands in arid and semiarid areas both are bounded to water conservation. Land degradation is increasingly associated to accelerated changes in land use, and farming systems in a context of rapid environmental and socio-economic changes. L. In broader perspective, soil and water conservation must be improved if food security and environmental stability is to be achieved locally and globally. This session is aimed to bring together specialist from different background with interest in sharing their experiences, expertise and challenges on optimizing yield, water and soil use in a changing world. Since land degradation affects least developed countries most, we especially encourage people from developing countries to submit their abstract to this session. The EGU has travel bursaries available to support some applicants (requires an early abstract submission) for whom we can also try to get funding for travel and registration costs. We are especially encouraging researchers working on the following topics to submit their abstract to our session:-
- Systemic approaches to improve soil and water conservation in crop (rainfed or deficitly irrigated), grazing and forest areas.
- Basic and applied studies on land degradation on a variety of scales; from the field and farm level to the watershed and village level.
- Development of tools to predict or monitor impact of land degradation on yield and other ecosystem goods and services.
- Incentives/barriers to changes related to SLM by farmers and other stakeholders under changing social or environmental conditions.
- Land conservation and enhancement of biodiversity, especially in areas of high natural values.
- Bridging the gap between scientific knowledge and its successful implementation by stakeholders and decision makers (e.g. government).
- Tools to identify priority hot spots for SLM adaptation practices.
AN2: Grazing as a management tool to build cultural landscapes
Description
Pastoralism is a human activity practiced worldwide by more than 500 million people. Its role as a modifier of land has been crucial throughout history either as a forest/shrub clearing or as one of the driving forces behind of many land degradation processes. The effects of grazing on environment are context-dependent on climate, topography and land management. This latter is usually adapted both to local physical conditions (rainfall, soil, slope, etc.) and to time-dependent cultural, economic and political factors. So, we intend, on the one hand, to expand the knowledge of different past and existing land management systems, ranging from subsistence farming to much more complex ways based on innovation and market strategies. And, on the other hand, we aim to better know how conservationist paradigms (e.g. European Union agri-environmental measures) as well as restoration strategies (e.g. fencing exclusion) have influenced, or are influencing, on the past/current land management at different territories/biomes. Therefore research and management experiences throughout the world which grazing be dealt as the most important factor are very welcome. This session is aimed at gather multidisciplinary works from different perspectives (applied or pure science): history, economy, society, policy, land planning, cultural legacy, animal welfare, ecology or geomorphology.AN3: Climate-Resilient Land Management: Integrating Nature-Based Solutions for Sustainable Land Use in a Changing Climate
Description
"In the face of accelerating climate change, land systemsspanning urban areas, agriculture, and forestsare under increasing pressure from extreme weather events, land degradation, and ecosystem shifts. Equally, unsustainable land management is a key driver of climate change and climate-related disasters. Thus, the Land-System Change and Climate Change planetary boundaries are deeply interrelated, so are the solutions. This session will explore how Nature-Based Solutions (NbS) for Land Management can be better planned and implemented, as well as associated benefits can be delivered more effectively, with a climate-informed approach. By integrating climate change considerations into land management, NbS can address critical issues in these two boundaries, such as soil degradation, land-use change, ecosystem shifts, and climate risks. Through real-world examples and policy insights, this session highlights the role of NbS in shaping climate-resilient landscapes. This includes showcasing innovative NbS for land management that mitigate climate-induced pressures and adapt to evolving climate risks, as well as gaining understanding of how accounting for climate change can improve the ways to restore, reduce, and avoid land degradation. Sub-topics- NbS in Land systems (forestry, agriculture, cities) mitigating climate-induced pressures, such as ecosystem health decline, changes in forest composition, heat stress, reduced crop yield, and declining soil fertility.
- Climate-resilient NbS for land restoration (e.g., ecosystem restoration tailored to anticipated climate shifts, rewilding initiatives accounting for future climate scenarios, and recovery of agricultural degraded lands with climate-smart farming systems)
- NbS and adaptive land management (i.e, NbS examples that adjust to evolving climate conditions such as increased flooding, prolonged droughts, accelerated soil erosion, and shifting ecosystems, through e.g. adaptive practices like dynamic conservation planning, climate-resilient forestry, and flexible agricultural systems designed to respond to changing seasonal patterns and extreme weather events).
- Policy innovations integrating NbS into land use regulations for climate adaptation (e.g., incentives for farmers practicing drought-tolerant agriculture, zoning regulations that prioritize green infrastructure in urban heat hotspots, and legal frameworks that support wetland restoration for flood protection).
- Using climate modeling to support planning, implementation and monitoring of NbS for Land Management (e.g., climate data helping identify areas that are most vulnerable to climate-induced degradation, use of climate projections to adjust land management practices of NbS, climate models simulating NbS effectiveness in preventing land system change or improving ecosystem resilience)

NH3: Human impact on erosion and connectivity in agricultural land
Description
Different types of human impacts (incl. climate change) can have detrimental effects on terrestrial and aquatic (eco)systems. These include changes in land use and different types of river engineering activities causing soil erosion, flooding and river channel degradation. Sustainable river and catchment management (incl. restoration efforts) require nature-based options to mitigate (or even reverse) the effects of different types of human interference and climate change. These, for example, include reforestation or the installation of different water retention measures such as riparian vegetation/buffer strips, soil conservation, erosion and flood control measures, the elimination of river bank protection, or other activities such as the removal of dams. Connectivity has emerged as an important conceptual framework for understanding and managing the transfer of surface water, sediment, nutrients and biota through landscape systems. (Dis-)connecting features can have large spatial and temporal implications on ecological, geomorphic, hydrological and biogeochemical processes through buffering water and material fluxes, thus forming neuralgic points for river and catchment management (incl. restoration) actions. Here we aim to create a diverse interdisciplinary session that reflects a broad range of research seeking to illustrate the role of nature-based solutions in managing hydro-geomorphic and ecological connectivity in a river and catchment management (incl. restoration) context.AN5: Innovative Solutions for Sustainable Andalusian Agriculture: Showcasing AEI Operational Groups

Description
We invite researchers, practitioners, and policymakers to contribute to our forthcoming session focused on "Nature-Based Solutions (NbS) for Agriculture and Natural Areas", with a particular emphasis on soil, water, and landscape management. As global challenges such as climate change, biodiversity loss, and food insecurity intensify, NbS present a promising pathway for sustainable agricultural practices and the restoration of natural ecosystems. This session aims to highlight innovative approaches that leverage natural processes to enhance soil health, improve water management, and promote landscape resilience. We seek submissions that explore diverse topics, including:- The application of NbS in regenerative agriculture and agroecology.
- Strategies for enhancing soil fertility and water retention through natural methods.
- Integrated landscape management practices that foster biodiversity and ecosystem services.
- Case studies demonstrating successful NbS implementation in agricultural settings.
- Policy implications and frameworks that support the adoption of NbS.
NH1: Nature based solution for increasing resilience to water-related hazards
Description
Natural hazards, such as slope instabilities, floods and droughts continue to pose significant threats to communities worldwide, especially in agro-ecosystems. These processes, exacerbated by the current soil management practices, are particularly relevant in semi-arid zones such as the agricultural areas (e.g. olive groves and vineyards) under Mediterranean climatic conditions. Since climate changes are increasing the frequency and intensity of these events, it becomes necessary to explore innovative and sustainable approaches to mitigate their impact in the environment. This proposed session is under the frame of the PNRR-NODES project (funded from the Italian MUR) and aims to shed light on the fundamental role of nature-based solutions (NbS) in mitigating the impact of water-related hazards in agroecosystems. The session invites contributions in the context of biological, agronomical, geological, geomorphological and hydrogeological topics. Furthermore, any contribution about the different applications of NbS to water-related hazard reduction with multidisciplinary approaches is welcome: a) proximal and remote sensing for measurement and monitoring the effects of NbS in agro-ecosystem (satellite observation, in-situ meteorological, hydrological, biological, agronomical measurements, geophysical surveys, laboratory samples-test); b) numerical and physical simulation of the effects of NbS and climate changes in different agro-ecosystems. Scientific applications include earth and environmental sciences topics such as climate changes, landslide hazards, soil water content measurements, water management, early warning systems and atmospheric circulation, as well as the influences of agricultural management on slope instabilities and plant health (e.g. NDVI correlations). By the end of this session, farmers and policymakers will gain a comprehensive understanding of the potential of nature-based solutions in building resilience against water-related hazards agro-ecosystems. The session will conclude by discussing the implications of integrating nature-based solutions into water-related disaster risk reduction strategies. This conference session proposal is part of the project NODES which has received funding from the MUR M4C2 1.5 of PNRR funded by the European Union - NextGenerationEU (Grant agreement no. ECS00000036).NH2: Nature-based solutions for urban water-scarce environments
Description
Water security, a critical factor for human well-being and socio-economic development, is under immediate threat from increasing water scarcity in cities worldwide. This scarcity, caused by factors such as population growth, unsustainable practices, and global warming-driven droughts, occurs when local demand exceeds availability. Future projections indicate that this threat will only intensify, expanding to more cities and particularly affecting socially or economically disadvantaged population sectors. Nature-based solutions (NbS) are particularly well-suited to addressing urban water-related challenges. A substantial body of literature, primarily developed in cities with high rainfall, indicates that implementing NbS can mitigate groundwater depletion, peak runoff volumes and diffuse pollution in receiving water bodies. However, fewer studies have assessed the performance of NbS in cities already facing water scarcity, such as those in arid or semi-arid regions. In such environments, we believe that NbS can contribute to water security if they are innovatively and inclusively planned and implemented through multi-level governance. Furthermore, there are unexplored opportunities to extend their benefits to the population, such as the use of eco-friendly materials for their construction. It is also essential to conduct long-term evaluations from a climate resilience perspective, employing modeling tools and probabilistic analyses.NH3: Paradigm shifts in wildfire management
Description
Wildfires are considered either a forest threat or a beneficial source of ecosystem services. However, the number of fires and length of fire seasons are growing as an effect of climate change. In the Mediterranean region, more than 40,000 fires a year were recorded between 2010 and 2016. Moreover, recent fire events on lands with high carbon content have begun to be especially concerning. Therefore, wildfire monitoring is more crucial than ever to mitigate the risks associated with unchecked wildfire. Managing these risks demands a trade-off between costs and efficiency. Current approaches involve high-cost suppression operations along with controversial policies that lead to inefficient risk management. To overcome these issues, new approaches promote groundbreaking technology, specifically NBS, training, guidelines, and policy recommendations to improve wildfire management, reduce the most harmful effects, and adapt fire management strategies to socioeconomic contexts and projected climate scenarios. In this session, we wish to engage researchers, professionals, legislators, and citizens to exchange experiences and discuss the impact of wildfires on nature and society, needs to prevent extreme wildfires, the role of land management strategies at different scales, and nature-based solutions for fire risk management across Europe.NH4: NBS and Biodiversity for climate change adaptation
Description
This session focusses on classification and prioritization systems for Nature-based Adaptation Solutions (NbS). One example has been developed in collaboration with Fundación Biodiversidad. This systematic approach covers both terrestrial and marine domains, aligning with the objectives of Spain's National Climate Change Adaptation Plan (PNACC-2). In this session we invite other initiaties and projects to show their NBS classification systems and databases. In a discussion we hope to learn and cross-fertilize the work that is being done across Europe and beyond. Join us to discuss the next steps on this topic.MET1: Climate-Resilient Land Management: Integrating Nature-Based Solutions for Sustainable Land Use in a Changing Climate

MET2: Advances in land ecosystem restoration monitoring using remote sensing and machine learning
Description
Today, land ecosystem restoration actions are among the proven solutions to reverse anthropogenic and climate-driven land degradation and desertification. Such actions have multiple advantages such as supporting ecosystem resilience (Ellison & Ifejika Speranza, 2020; Sacande et al., 2021), increasing carbon sequestration (Dixon et al., 2016), restoring hydrological catchment characteristics (Anderson et al., 2010; Carrick et al., 2019), etc. Thus, ecosystem restoration actions are a global priority (Robinson et al., 2023). Indicative of this is that UN named years 2021-2030 as the Decade on Ecosystem Restoration (Waltham et al., 2020), while the EU incorporates such policies in the Green Deal (Gann et al., 2019) and has announced action like the 3 billion additional trees pledge. Although restoration actions do take place, too few of these are monitored thereafter (Nadal-Romero et al., 2023). Monitoring methods based on remote sensing could be a viable alternative to high-cost and labor-intensive conventional ones (de Almeida et al., 2020). Meanwhile, Machine Learning has a great advantage in dealing with the nonlinear ecological relationships (Guo et al., 2023). In this session we aim to explore:- State of the art and advances in land ecosystem monitoring using RS
- Artificial intelligence and automated monitoring for assisting conservation and restoration of land ecosystems
- Decision support tools for land ecosystem restoration
- Bridging space-time scale gaps and tackling uncertainties
- Novel datasets and indicators from RS and/or for training AI systems
- Ground truthing methods for RS

UR1: Nature-based solutions for air quality improvement and temperature reduction in urban areas
Description
Urban areas are currently facing challenges associated with densification and climate change, namely air pollution and urban heating. Air pollution is considered by the World Health Organization to be the greatest environmental risk to human health, causing the loss of healthy years of life and, in the worst cases, preventable deaths. Heat-related mortality is also been increasing due to climate change, escalating urbanization and a progressively ageing population. Nature-based solutions (NBS) are presented as a sustainable way to address current and future environmental challenges. This session welcomes field studies and modelling studies across micro, local or urban scales, using numerical or physical models that quantify the impact of NBS in the atmospheric environment. This session seeks to discuss innovative methods to assess NBS benefits and co-benefits in the context of climate change adaptation; particularly its effectiveness in reducing air pollution and/or urban heat.UR2: Working Backwards towards a Theory of Change for a massive upscaling of NBS in cities
Description
This workshop session aims to develop a Theory of Change for scaling up nature-based solutions (NBS) in urban areas. It begins with a five-minute introduction to the panel and workshop concept, followed by a 20-minute panel discussion where four experts present their theories of change, emphasizing 1-2 crucial steps needed to scale NBS in cities. Participants then engage in a ""Working Backwards"" exercise, using ChatGPT in teams to envision a 2050 news story celebrating a citys greening success, highlighting key initiatives from 2025-2035 that made the difference. A 10-minute feedback session follows, where teams share their news releases, exploring how these stories shape theories for scaling NBS.

UR3: Upscaling small nature-based solutions for large scale green frameworks in urban regions and metropolises
Description
There is an urgent need to create nature-based solutions both in rural and in urban conditions. The way we accelerate these solutions is often a weak point in policies and specifically in practice. In many cases the pilot project or experiment is also the end-point, while it should be and was supposed to be the starting point of a more fundamental change towards a nature-based development. In this session we would like to put this question on the table: how can we make it happen that small-scale nature-based solutions can be upscaled to green urban metropolises and regions? This session aims to bring together best practices from different parts of the world, and is open for a selection of presentations to be submitted by participants. To start the session we will present two case studies: one from Monterrey, Mexico and one from Randstad, the Netherlands. Both cases are very different and therefore we hope to draw common lessons about the strategic dos and donts. The case study from Mexico (presented by Tecnológico de Monterrey) will share specific context of Latin America with a strong emphasis on inequity when it comes to health implications of access to nature-based solutions and green spaces. Nature is not for everyone evenly close. The Randstad case is presented by Delft University of Technology and emphasizes the small scale urban ecology approach on its campus and how this can be scaled up to an urban level, given current problems in agriculture, biodiversity and housing and the Dutch planning doctrine. The session is open for three more short presentations, which we would kindly invite to propose by submitting an abstract for our session. We are seeking case studies and research from additional perspectives to the Mexican and Dutch one, which illustrate the connection of smaller nature-based solutions into large scale green infrastructure frameworks at regional or metropolitan scale. After these (max 5) presentation we aim to organize a discussion with the audience to distillate successful design principles for upscaling nature-based solutions in urban regions. In order to create a kick-start of the session we ask each speaker to, at least, identify their three most important or successful design principles.UR4: Â Nature based solutions for restoration of urban water cycle
Description
Urban areas have become increasingly vulnerable to climate change. Having covered by impermeable surfaces to provide public services such as buildings for schools, hospitals, houses, or roads and having decreased amount of green areas to provide area for increasing population are considered as the main reasons. As a result, infiltration is reduced leading to interruption of urban water cycle. Consequently, the probability of floods or drought and water scarcity are increased and posed risk on urban ecosystem. Nature based solutions are proposed to provide sustainable solutions for many problems. Restoration of water cycle is one of the most important benefit that nature based solutions can support in addition to many other advantages such as water treatment, air quality improvement, biodiversity enhancement, and social engagement. So it is crucial to compile and present studies about nature based solution applications to improve water cycle in urban areas at any scale.UR5: Nature-based solutions for Agriculture Managed Aquifer Recharge
Description
The report on Nature-based solutions for Water, conducted in 2018 by the UN, highlighted the need to seek new solutions for water management based on the use of ecosystems and the physical environment through which it transits. In this sense, aquifers, the main freshwater reservoirs of our planet, are essential to store and provide water supply, to help its natural purification and to provide a large number of environmental benefits. The current scenario of population growth and global warming necessitates the enhancement of the ecosystem services that groundwater and subsoil provide. The remarkable advances in technology and scientific knowledge in the field of hydrogeology and agronomy give rise to a wide variety of solutions to improve groundwater management, in terms of quality, quantity and regulation. Among these techniques, the agricultural managed aquifer recharge (Ag-MAR), in which the managed recharge of aquifers is carried out through irrigation canals, flood irrigation and winter irrigation, can be a tool with great potential to recover the return flows produced by the irruption of localized irrigation or the abandonment of croplands. In this session on Agri-MAR we want to make known the potential of these SbN, sharing a series of experiences that are already being developed and creating a necessary debate so that this type of solutions has more and more prominence.UR6: Nature-based solutions for urban water-scarce environments
Description
Water security, a critical factor for human well-being and socio-economic development, is under immediate threat from increasing water scarcity in cities worldwide.

NH3: Human impact on erosion and connectivity in agricultural land
Description
Different types of human impacts (incl. climate change) can have detrimental effects on terrestrial and aquatic (eco)systems. These include changes in land use and different types of river engineering activities causing soil erosion, flooding and river channel degradation. Sustainable river and catchment management (incl. restoration efforts) require nature-based options to mitigate (or even reverse) the effects of different types of human interference and climate change. These, for example, include reforestation or the installation of different water retention measures such as riparian vegetation/buffer strips, soil conservation, erosion and flood control measures, the elimination of river bank protection, or other activities such as the removal of dams. Connectivity has emerged as an important conceptual framework for understanding and managing the transfer of surface water, sediment, nutrients and biota through landscape systems. (Dis-)connecting features can have large spatial and temporal implications on ecological, geomorphic, hydrological and biogeochemical processes through buffering water and material fluxes, thus forming neuralgic points for river and catchment management (incl. restoration) actions. Here we aim to create a diverse interdisciplinary session that reflects a broad range of research seeking to illustrate the role of nature-based solutions in managing hydro-geomorphic and ecological connectivity in a river and catchment management (incl. restoration) context.AN5: Innovative Solutions for Sustainable Andalusian Agriculture: Showcasing AEI Operational Groups

NH1: Nature based solution for increasing resilience to water-related hazards
Description
Natural hazards, such as slope instabilities, floods and droughts continue to pose significant threats to communities worldwide, especially in agro-ecosystems. These processes, exacerbated by the current soil management practices, are particularly relevant in semi-arid zones such as the agricultural areas (e.g. olive groves and vineyards) under Mediterranean climatic conditions. Since climate changes are increasing the frequency and intensity of these events, it becomes necessary to explore innovative and sustainable approaches to mitigate their impact in the environment. This proposed session is under the frame of the PNRR-NODES project (funded from the Italian MUR) and aims to shed light on the fundamental role of nature-based solutions (NbS) in mitigating the impact of water-related hazards in agroecosystems. The session invites contributions in the context of biological, agronomical, geological, geomorphological and hydrogeological topics. Furthermore, any contribution about the different applications of NbS to water-related hazard reduction with multidisciplinary approaches is welcome: a) proximal and remote sensing for measurement and monitoring the effects of NbS in agro-ecosystem (satellite observation, in-situ meteorological, hydrological, biological, agronomical measurements, geophysical surveys, laboratory samples-test); b) numerical and physical simulation of the effects of NbS and climate changes in different agro-ecosystems. Scientific applications include earth and environmental sciences topics such as climate changes, landslide hazards, soil water content measurements, water management, early warning systems and atmospheric circulation, as well as the influences of agricultural management on slope instabilities and plant health (e.g. NDVI correlations). By the end of this session, farmers and policymakers will gain a comprehensive understanding of the potential of nature-based solutions in building resilience against water-related hazards agro-ecosystems. The session will conclude by discussing the implications of integrating nature-based solutions into water-related disaster risk reduction strategies. This conference session proposal is part of the project NODES which has received funding from the MUR M4C2 1.5 of PNRR funded by the European Union - NextGenerationEU (Grant agreement no. ECS00000036).NH2: Nature-based solutions for urban water-scarce environments
Description
Water security, a critical factor for human well-being and socio-economic development, is under immediate threat from increasing water scarcity in cities worldwide. This scarcity, caused by factors such as population growth, unsustainable practices, and global warming-driven droughts, occurs when local demand exceeds availability. Future projections indicate that this threat will only intensify, expanding to more cities and particularly affecting socially or economically disadvantaged population sectors. Nature-based solutions (NbS) are particularly well-suited to addressing urban water-related challenges. A substantial body of literature, primarily developed in cities with high rainfall, indicates that implementing NbS can mitigate groundwater depletion, peak runoff volumes and diffuse pollution in receiving water bodies. However, fewer studies have assessed the performance of NbS in cities already facing water scarcity, such as those in arid or semi-arid regions. In such environments, we believe that NbS can contribute to water security if they are innovatively and inclusively planned and implemented through multi-level governance. Furthermore, there are unexplored opportunities to extend their benefits to the population, such as the use of eco-friendly materials for their construction. It is also essential to conduct long-term evaluations from a climate resilience perspective, employing modeling tools and probabilistic analyses.NH3: Paradigm shifts in wildfire management
Description
Wildfires are considered either a forest threat or a beneficial source of ecosystem services. However, the number of fires and length of fire seasons are growing as an effect of climate change. In the Mediterranean region, more than 40,000 fires a year were recorded between 2010 and 2016. Moreover, recent fire events on lands with high carbon content have begun to be especially concerning. Therefore, wildfire monitoring is more crucial than ever to mitigate the risks associated with unchecked wildfire. Managing these risks demands a trade-off between costs and efficiency. Current approaches involve high-cost suppression operations along with controversial policies that lead to inefficient risk management. To overcome these issues, new approaches promote groundbreaking technology, specifically NBS, training, guidelines, and policy recommendations to improve wildfire management, reduce the most harmful effects, and adapt fire management strategies to socioeconomic contexts and projected climate scenarios. In this session, we wish to engage researchers, professionals, legislators, and citizens to exchange experiences and discuss the impact of wildfires on nature and society, needs to prevent extreme wildfires, the role of land management strategies at different scales, and nature-based solutions for fire risk management across Europe.NH4: NBS and Biodiversity for climate change adaptation
Description
This session focusses on classification and prioritization systems for Nature-based Adaptation Solutions (NbS). One example has been developed in collaboration with Fundación Biodiversidad. This systematic approach covers both terrestrial and marine domains, aligning with the objectives of Spain's National Climate Change Adaptation Plan (PNACC-2). In this session we invite other initiaties and projects to show their NBS classification systems and databases. In a discussion we hope to learn and cross-fertilize the work that is being done across Europe and beyond. Join us to discuss the next steps on this topic.MET1: Climate-Resilient Land Management: Integrating Nature-Based Solutions for Sustainable Land Use in a Changing Climate
Description
In the face of accelerating climate change, land systemsspanning urban areas, agriculture, and forestsare under increasing pressure from extreme weather events, land degradation, and ecosystem shifts. Equally, unsustainable land management is a key driver of climate change and climate-related disasters. Thus, the Land-System Change and Climate Change planetary boundaries are deeply interrelated, so are the solutions. This session will explore how Nature-Based Solutions (NbS) for Land Management can be better planned and implemented, as well as associated benefits can be delivered more effectively, with a climate-informed approach. By integrating climate change considerations into land management, NbS can address critical issues in these two boundaries, such as soil degradation, land-use change, ecosystem shifts, and climate risks. Through real-world examples and policy insights, this session highlights the role of NbS in shaping climate-resilient landscapes. This includes showcasing innovative NbS for land management that mitigate climate-induced pressures and adapt to evolving climate risks, as well as gaining understanding of how accounting for climate change can improve the ways to restore, reduce, and avoid land degradation. Sub-topics - NbS in Land systems (forestry, agriculture, cities) mitigating climate-induced pressures, such as ecosystem health decline, changes in forest composition, heat stress, reduced crop yield, and declining soil fertility. - Climate-resilient NbS for land restoration (e.g., ecosystem restoration tailored to anticipated climate shifts, rewilding initiatives accounting for future climate scenarios, and recovery of agricultural degraded lands with climate-smart farming systems) - NbS and adaptive land management (i.e, NbS examples that adjust to evolving climate conditions such as increased flooding, prolonged droughts, accelerated soil erosion, and shifting ecosystems, through e.g. adaptive practices like dynamic conservation planning, climate-resilient forestry, and flexible agricultural systems designed to respond to changing seasonal patterns and extreme weather events). - Policy innovations integrating NbS into land use regulations for climate adaptation (e.g., incentives for farmers practicing drought-tolerant agriculture, zoning regulations that prioritize green infrastructure in urban heat hotspots, and legal frameworks that support wetland restoration for flood protection). - Using climate modeling to support planning, implementation and monitoring of NbS for Land Management (e.g., climate data helping identify areas that are most vulnerable to climate-induced degradation, use of climate projections to adjust land management practices of NbS, climate models simulating NbS effectiveness in preventing land system change or improving ecosystem resilience) Session Format:- Duration: 60-75 minutes
- Number of Talks: 6-8 speakers, each with a 5-7 minute lightning talk.
- Audience Interaction: 15-20 minutes of Q&A and discussion at the end.
MET2: Advances in land ecosystem restoration monitoring using remote sensing and machine learning
Description
Today, land ecosystem restoration actions are among the proven solutions to reverse anthropogenic and climate-driven land degradation and desertification. Such actions have multiple advantages such as supporting ecosystem resilience (Ellison & Ifejika Speranza, 2020; Sacande et al., 2021), increasing carbon sequestration (Dixon et al., 2016), restoring hydrological catchment characteristics (Anderson et al., 2010; Carrick et al., 2019), etc. Thus, ecosystem restoration actions are a global priority (Robinson et al., 2023). Indicative of this is that UN named years 2021-2030 as the Decade on Ecosystem Restoration (Waltham et al., 2020), while the EU incorporates such policies in the Green Deal (Gann et al., 2019) and has announced action like the 3 billion additional trees pledge. Although restoration actions do take place, too few of these are monitored thereafter (Nadal-Romero et al., 2023). Monitoring methods based on remote sensing could be a viable alternative to high-cost and labor-intensive conventional ones (de Almeida et al., 2020). Meanwhile, Machine Learning has a great advantage in dealing with the nonlinear ecological relationships (Guo et al., 2023). In this session we aim to explore:- State of the art and advances in land ecosystem monitoring using RS
- Artificial intelligence and automated monitoring for assisting conservation and restoration of land ecosystems
- Decision support tools for land ecosystem restoration
- Bridging space-time scale gaps and tackling uncertainties
- Novel datasets and indicators from RS and/or for training AI systems
- Ground truthing methods for RS

Description
The purpose of this course is to present the current best practices for applying bioremediation and reductive technologies to treat common environmental contaminants of concern. The potential audience includes engineers and scientists who are interested in learning about fundamentals and some advanced concepts from industry experts. This short course will provide fundamental overviews by consolidating decades of experience in applying enhanced reductive dechlorination (ERD), in situ chemical reduction (ISCR) and biogeochemical reduction (BGCR) technologies. The course is intended to benefit experienced practitioners but is primarily intended for those who are less experienced using in situ remediation techniques. The course will be divided into four sections each intended to last for 1 hour. At least 15 minutes will be allocated for discussion during each section. This will be accomplished by focusing on key topics of fundamental science, design considerations, application methods, and using case studies to illustrate how all of these can come together successfully. These will include a presentation of: Fundamental science including oxidative versus reductive pathways, abiotic versus biotic processes, the various types of microbes that are commonly used in bioremediation, bioaugmentation, abiotic versus biotic degradation pathways, biogeochemical chemistry, types of electron donors, contaminants commonly treated with reductive technologies and their various reduction potential. A basic understanding of site geology and hydrology will be assumed. Design considerations will discuss critical design parameters, dosage strategies for different electron donors, lessons learned of when and where to use different technologies, modifications made due to site constraints, monitoring programs, strategies to achieve various remedial goals, and process optimization. Field applications would describe the various commonly used application strategies and equipment as well as outlining the differences between a field pilot study and full-scale efforts. Case studies will be presented illustrating these thoughts and processes and how they have been successfully combined for ERD, ISCR and BGCR.MET4: Social Innovation Labs: A Collaborative Space for Co-creation and Social Transformation

UR1: Nature-based solutions for air quality improvement and temperature reduction in urban areas
Description
Urban areas are currently facing challenges associated with densification and climate change, namely air pollution and urban heating. Air pollution is considered by the World Health Organization to be the greatest environmental risk to human health, causing the loss of healthy years of life and, in the worst cases, preventable deaths. Heat-related mortality is also been increasing due to climate change, escalating urbanization and a progressively ageing population. Nature-based solutions (NBS) are presented as a sustainable way to address current and future environmental challenges. This session welcomes field studies and modelling studies across micro, local or urban scales, using numerical or physical models that quantify the impact of NBS in the atmospheric environment. This session seeks to discuss innovative methods to assess NBS benefits and co-benefits in the context of climate change adaptation; particularly its effectiveness in reducing air pollution and/or urban heat.UR2: Working Backwards towards a Theory of Change for a massive upscaling of NBS in cities
Description
This workshop session aims to develop a Theory of Change for scaling up nature-based solutions (NBS) in urban areas. It begins with a five-minute introduction to the panel and workshop concept, followed by a 20-minute panel discussion where four experts present their theories of change, emphasizing 1-2 crucial steps needed to scale NBS in cities. Participants then engage in a ""Working Backwards"" exercise, using ChatGPT in teams to envision a 2050 news story celebrating a citys greening success, highlighting key initiatives from 2025-2035 that made the difference.

UR3: Upscaling small nature-based solutions for large scale green frameworks in urban regions and metropolises
Description
There is an urgent need to create nature-based solutions both in rural and in urban conditions. The way we accelerate these solutions is often a weak point in policies and specifically in practice. In many cases the pilot project or experiment is also the end-point, while it should be and was supposed to be the starting point of a more fundamental change towards a nature-based development. In this session we would like to put this question on the table: how can we make it happen that small-scale nature-based solutions can be upscaled to green urban metropolises and regions? This session aims to bring together best practices from different parts of the world, and is open for a selection of presentations to be submitted by participants. To start the session we will present two case studies: one from Monterrey, Mexico and one from Randstad, the Netherlands. Both cases are very different and therefore we hope to draw common lessons about the strategic dos and donts. The case study from Mexico (presented by Tecnológico de Monterrey) will share specific context of Latin America with a strong emphasis on inequity when it comes to health implications of access to nature-based solutions and green spaces. Nature is not for everyone evenly close. The Randstad case is presented by Delft University of Technology and emphasizes the small scale urban ecology approach on its campus and how this can be scaled up to an urban level, given current problems in agriculture, biodiversity and housing and the Dutch planning doctrine. The session is open for three more short presentations, which we would kindly invite to propose by submitting an abstract for our session. We are seeking case studies and research from additional perspectives to the Mexican and Dutch one, which illustrate the connection of smaller nature-based solutions into large scale green infrastructure frameworks at regional or metropolitan scale. After these (max 5) presentation we aim to organize a discussion with the audience to distillate successful design principles for upscaling nature-based solutions in urban regions. In order to create a kick-start of the session we ask each speaker to, at least, identify their three most important or successful design principles.UR4: Â Nature based solutions for restoration of urban water cycle
Description
Urban areas have become increasingly vulnerable to climate change. Having covered by impermeable surfaces to provide public services such as buildings for schools, hospitals, houses, or roads and having decreased amount of green areas to provide area for increasing population are considered as the main reasons. As a result, infiltration is reduced leading to interruption of urban water cycle. Consequently, the probability of floods or drought and water scarcity are increased and posed risk on urban ecosystem. Nature based solutions are proposed to provide sustainable solutions for many problems. Restoration of water cycle is one of the most important benefit that nature based solutions can support in addition to many other advantages such as water treatment, air quality improvement, biodiversity enhancement, and social engagement. So it is crucial to compile and present studies about nature based solution applications to improve water cycle in urban areas at any scale.UR5: Nature-based solutions for Agriculture Managed Aquifer Recharge
Description
The report on Nature-based solutions for Water, conducted in 2018 by the UN, highlighted the need to seek new solutions for water management based on the use of ecosystems and the physical environment through which it transits. In this sense, aquifers, the main freshwater reservoirs of our planet, are essential to store and provide water supply, to help its natural purification and to provide a large number of environmental benefits. The current scenario of population growth and global warming necessitates the enhancement of the ecosystem services that groundwater and subsoil provide. The remarkable advances in technology and scientific knowledge in the field of hydrogeology and agronomy give rise to a wide variety of solutions to improve groundwater management, in terms of quality, quantity and regulation. Among these techniques, the agricultural managed aquifer recharge (Ag-MAR), in which the managed recharge of aquifers is carried out through irrigation canals, flood irrigation and winter irrigation, can be a tool with great potential to recover the return flows produced by the irruption of localized irrigation or the abandonment of croplands. In this session on Agri-MAR we want to make known the potential of these SbN, sharing a series of experiences that are already being developed and creating a necessary debate so that this type of solutions has more and more prominence.UR6: Nature-based solutions for urban water-scarce environments
Description
Water security, a critical factor for human well-being and socio-economic development, is under immediate threat from increasing water scarcity in cities worldwide. This scarcity, caused by factors such as population growth, unsustainable practices, and global warming-driven droughts, occurs when local demand exceeds availability. Future projections indicate that this threat will only intensify, expanding to more cities and particularly affecting socially or economically disadvantaged population sectors. Nature-based solutions (NbS) are particularly well-suited to addressing urban water-related challenges. A substantial body of literature, primarily developed in cities with high rainfall, indicates that implementing NbS can mitigate groundwater depletion, peak runoff volumes and diffuse pollution in receiving water bodies. However, fewer studies have assessed the performance of NbS in cities already facing water scarcity, such as those in arid or semi-arid regions. In such environments, we believe that NbS can contribute to water security if they are innovatively and inclusively planned and implemented through multi-level governance. Furthermore, there are unexplored opportunities to extend their benefits to the population, such as the use of eco-friendly materials for their construction. It is also essential to conduct long-term evaluations from a climate resilience perspective, employing modeling tools and probabilistic analyses.SB1: Harnessing Awareness and Partnerships for Sustainable Nature-Based Solutions
Description
The role of Nature-Based Solutions (NBS) in addressing climate, water, and land challengessuch as floods, droughts, water scarcity, land degradation, soil restoration, and pollution controlis increasingly recognized within both scientific and professional communities. Despite growing evidence of the benefits of NBS, effective implementation requires a collaborative, interdisciplinary approach. This session will feature case studies that demonstrate how NBS can be integrated into water and land management, highlighting successful collaborations among decision-makers, civil society, researchers, academia, and the private sector, including landowners. Aligned with the Sustainable Development Goals (e.g., Target 6.6) and supported by the IAHS ""Helping Decade"" (Working Group 2.5), this session emphasizes the critical importance of stakeholder engagement, cross-sector partnerships, and the integration of NBS principles into educational curricula to scale sustainable water and land management solutions globally. In this session, we invite:- Studies showcasing successful applications of NBS in mitigating hydrometeorological extremes, such as floods and droughts;
- Studies combining NBS with cross-sectoral collaboration, stakeholder engagement, and transdisciplinary approaches that bridge academia and civil society;
- Studies incorporating social science perspectives on NBS, including public perception surveys and citizen science to assess NBS effectiveness, legitimacy, and acceptance;
- Studies exploring NBS concepts in (higher) education through hands-on learning approaches;
- Studies examining NBS and other sustainable practices for soil and water conservation and restoration;
- Discussions on integrating diverse disciplines in NBS development, addressing both challenges and benefits of this approach;
- Overviews of current policies, incentives, and regulations that affect NBS implementation, including recommendations for policy changes to support NBS.
SB2: Inclusive Governance of Nature-Based Solutions: Environmental Justice and transectoral dimensions
Description
This session will discuss three interrelated aspects of NbS governance: i) transectoral governance, ii) inclusive governance and iii) environmental justice. Nature-based Solutions can produce several types of co-benefits: climate adaptation, biodiversity conservation, risk management, sustainable agriculture, water quality preservation, etc. At the city scale, or at a given territory, these co-benefits are managed by distinct policy sectors, with different departments or institutions, services, agents with different working cultures and procedures, etc. This transectoral aspect of Nature-based Solutions, given the sectoral organization of territories, are usually seen as an obstacle to define, implement and maintain effectively Nature-based Solutions. This session aims at discussing this transectoral aspect of NbS: what are exactly the obstacles produced by the transectoral aspects of NbS, how are they materializing in practice? What are the trade-offs between stakeholders when designing, implementing and maintaining NbS? How are these obstacles overcome by actors on the ground? Are there governance mechanisms or innovations actors develop in practice to work together beside the so-called policy siloes? Nature-based Solutions are also supposed to enable inclusive governance, by including stakeholders that are outside the classical policy-making boundaries: associations, inhabitants, even non-humans ? But in practice, are NbS really inclusive? How is this inclusiveness materializing on the ground? Who is included when defining, implementing and maintaining NbS and who is not? How is this inclusivity of governance being used by stakeholders to politicize or depoliticize NbS? Research on NbS has shown that participatory processes are essential for achieving more just and equitable outcomes. Recognizing that transfer of power occurs at higher levels of participation is crucial for understanding the role of nature and ecology, and is vital for creating more equitable and effective environmental policies and practices. In this sense, Environmental Justice (EJ) examines distributive justice (regarding where are NbS allocated), recognition justice (whose values are articulated in NbS) and procedural justice (how decision-making processes take place and who participates). Often, NbS are considered in terms of distributive justice, overlooking dimensions of procedural and recognition justice. Therefore, designing NbS for all imply integrating the equitable allocation of NbS, inclusive participation in the governance process of NbS, and the integration of values and capabilities of different silos and stakeholders in the co-production of NbS. This session will incorporate discussions on the topic including (but not excluding): how do power relations take place in negotiation processes involving NbS? Who are the winners and losers in NbS implementations? Whose values and possible benefits of NbS are considered? What are the methods for assessing EJ in NbSs framework and practices? We invite contributions from all disciplines discussing governance issues related to NbS to send a summary stating the research questions, giving their theoretical framework but also empirical aspects of the research, and presenting some highlights. Contributions should state if they wish to contribute to a specific angle of the session (Transectoral; Inclusivity; Environmental Justice).SB3: Socio-ecological, socio-cultural, socio-political and socio-economic aspects of NBS
Description
"The concept of Nature based solutions (NBS) aims to simultaneously provide environmental, social and economic benefits for more sustainable communities. A key success factor in the implementation, acceptance, and appropriation of NBS is ensuring that interventions address the needs and ambitions of the communities where they are established, while distributing benefits fairly and equitably among stakeholders and citizens. To foster this buy-in of the communities, citizens and stakeholders can play active roles in the co-design, co-development, co-monitoring, and co-evaluation of NBS, enabling them to contribute their own interests and needs. This participatory approach unveils the full range of potential NBS benefits, encompassing socio-ecological, socio-cultural, socio-political, and socio-economic dimensions. Thus, NBS can serve as a valuable tool for fostering more inclusive communities through participative and collaborative practices in local governance. However, particularly in terms of societal benefits, there remains a need for more scientific evidence and examples of good practices to inspire, replicate, and upscale NBS implementation. However, especially in terms of benefits for the society, there is still need for more scientific evidence and good practice examples for inspiration, replication and upscaling to adopt NBS to a larger scale and to mobilise stakeholders and the civil society. The session aims to gather insights and evidence from current research and practical applications. Together, we will reflect on promising pathways and strategies for mainstreaming NBS across diverse fields and communities."SB4: The institutionalisation of nature-based solutions: policy tools and approaches
Description
This session will delve into the institutionalisation of nature-based solutions (NbS), focusing on the policy tools, governance approaches, and key actors driving their adoption. Participants should explore how NbS are being integrated into policy frameworks at various scales, examining case studies highlighting successes and challenges through which institutionalisation is achieved. The discussion will address how NbS are inserted in climate, environmental and spatial planning laws, regulations, and spatial plans. It may also explore how the roles of government, private sector, and civil society are foreseen in policy tools as drivers for fostering cross-sectoral collaboration alongside mechanisms to ensure equity and sustainability. By identifying best practices and innovative strategies, the session aims to equip policymakers and practitioners with insights to scale up NbS for climate resilience and biodiversity conservation.SB5: Open session for Science Brokers for Transitioning to a Climate Resilient and Circular Society
Description
"We invite submissions for sessions exploring the vital role of science brokers in facilitating the transition to a climate-resilient and circular society. As the impacts of climate change intensify, innovative approaches are essential to bridge the gap between scientific research, policy implementation, and community engagement. Science brokers serve as critical intermediaries, translating complex scientific knowledge into actionable insights that empower stakeholders across sectors. This session aims to investigate the mechanisms, challenges, and successes of science brokerage in promoting sustainable practices including nature based solutions and circular economy principles.
