Abstract: In this study, we apply the bow-tie risk analysis framework to map the causes and consequences of decline or loss of five key Irish Sea ecosystem components: intertidal sandflats and mudflats, burrowing fauna including Dublin Bay prawn Nephrops norvegicus, blue mussel Mytilus edulis, commercially harvested fish and wintering waterbirds. Main activities exerting multiple pressures on the Irish Sea ecosystem include energy production from offshore wind farms, tourism and leisure, fishing, transport, agriculture, urban and industrial uses and waste treatment and disposal. All of them can contribute to decline in condition or loss of critical habitats and biota, leading to significant ecological, economic and sociocultural consequences. Understanding these consequences is essential for designing appropriate management responses. The bow-tie approach allows management risks to be identified and highlights the most impactful control points for intervention to prevent or mitigate adverse biodiversity events.

Abstract: The Baltic sturgeon Acipenser oxyrinchus, once widespread in rivers draining to the Baltic Sea, was extirpated by overfishing and habitat degradation and is now the focus of a basin-wide restoration programme. Since 2006, more than seven million hatchery-reared juveniles have been released in Baltic rivers, yet the movements, habitat use and survival of stocked fish remain poorly quantified. HaffStör aims to close these knowledge gaps and to provide an operational basis for adaptive, cross-border management of the recovering population in the Oder River–Szczecin Lagoon system (Germany/Poland).The project combines movement ecology, conservation biology and social sciences in four interconnected work packages. First, we optimise rearing protocols, comparing juveniles produced under different degrees of environmental control (ambient vs. static recirculating aquaculture systems), coupled with behavioural experiments on habitat choice and anti-predator responses. Second, we release tagged juveniles in the Lower Oder and Szczecin Lagoon and track their movements using active and passive acoustic telemetry, complemented by habitat mapping and benthic sampling, to identify key migration routes, habitat utilisation and zones of overlap with human activities, mainly associated with fisheries and navigation. Third, we develop and test a standardised, cost-effective monitoring framework, based on passive gears, fishery-independent surveys and environmental DNA, aligned with Bern Convention guidelines and intended to be transferable to other Baltic catchments. Fourth, we establish cooperation with commercial fisheries through targeted outreach to initiate structured by-catch reporting, co-designed surveys and joint project activities.By integrating ecological and fishery data, HaffStör will deliver robust estimates of juvenile survival and mortality drivers, refine release and monitoring strategies and generate spatially-explicit assessments of by-catch risk. Beyond new scientific insights into Baltic sturgeon ecology, the project seeks to strengthen stewardship amongst local communities and practitioners and to support evidence-based, transnational governance for this flagship migratory species.

Abstract: Phosphorus sustains global food production and is, therefore, of crucial importance to human nutrition and health. However, its mismanagement can lead to water pollution and environmental degradation in addition to low crop yields. In many parts of sub-saharan Africa, phosphorus deficiency constrains agricultural productivity and exacerbates food insecurity. Despite these challenges, phosphorus remains a fragmented topic in global and African policy. To address these issues, the 8th Sustainable Phosphorus Summit (SPS8) was convened in Africa for the first time. SPS8 took place in Accra, Ghana, between 30th September and 3rd October 2025. The Summit was an international collaboration, with co-conveners from the Council for Scientific and Industrial Research (CSIR) – Ghana, the Forum for Agricultural Research in Africa (FARA), The UK Centre for Ecology & Hydrology West Africa Office, Lancaster University and Rothamsted Research. In this paper, we give a detailed overview of the key messages and insights that emerged from highlight talks, lectures, working groups and field trips. We also discuss and reflect on the challenges of delivering an inclusive summit, from designing solutions to benefit-sharing. SPS8 demonstrates that inclusive, cross-sector knowledge-exchange events are crucial to support and enable phosphorus sustainability on the continent of Africa and globally and to enable the next generation of interdisciplinary phosphorus researchers.

Abstract: In response to climate change, the landmark Paris Agreement established a set of goals to achieve climate neutrality and limit global warming. To help investors and companies contribute to these goals, the EU adopted a taxonomy for sustainable activities and, in line with it investments, must do no significant harm, as indicated by the Recovery and Resilience Facility Regulation. Since its inception, the Environmental Impact Assessment (EIA) procedure has aimed to minimise impacts of projects that could significantly damage the environment. Certainly, there are recognised weaknesses in the EIA, but its fitness to address complex environmental challenges, such as climate change, is unmatched. Considering the importance of EIA in ensuring scaling-up sustainable energy-related investments, NetDeal focuses on providing innovative and easy-to-use methods to improve EIA worldwide and combines policy analysis and EIA assessment data into complex networks. First, we analyse models of impact assessment (IA) legislation that can make recommendations about how IA can change to fit the global effort to tackle the energy and resource crises. Second, we will expose best practice models and investigate through network-related statistical analyses the collaboration links established in each EIA stage, which are behind successful projects from the perspective of productivity, circular economy, adaptation to climate change and reaching the goal of zero net emissions. Third, using Exponential Random Graph Models, I will explore the dynamic interaction between EIA stakeholders to diagnose the organisational structures and factors that strongly influence these projects. Last, I will create an integrated multi-layer EIA framework to improve the EIA effectiveness. The findings will be translated into the economic sector and provide new instruments to facilitate a streamlined EIA procedure that facilitates the adoption of urgent measures to mitigate the current energy crisis.

Abstract: Humanity faces environmental crises on a scale that demands new scientific paradigms. While valuable, the application of artificial intelligence has largely been confined to a predictive role—a paradigm insufficient for the transformative action now required. We argue for a shift toward a generative framework, repositioning AI from an analytical tool to a facilitator of synthesis and communication. This perspective introduces a vision where advanced generative models, including text-to-video technologies, create dynamic, experiential simulations of designed ecosystems. This allows stakeholders to not only see a proposed design, but also to witness its potential dynamics, such as how a restored forest matures or how green infrastructure responds to climate events. Crucially, this approach empowers AI to act as a representative for non-human species, synthesizing data to visualize their needs. However, I emphasize the critical distinction between photorealistic visual rendering and rigorous biophysical simulation; the former must be grounded in the latter to avoid misleading outcomes. I critically examine the approach's inherent challenges, including the environmental footprint of these models, and argue for an indispensable "expert-in-the-loop" framework to guide and validate these powerful new tools. This paradigm shift has profound implications for scientific methodology and public engagement, heralding an era where interdisciplinary teams leverage AI to visualize, deliberate, and collaboratively shape a resilient planet.

Abstract: EU chemical regulation remains slow, costly, and prone to “ecological surprises” such as unforeseen negative impacts, delayed neonicotinoid bans and ongoing pollinatordecline. Current approaches create silos, overlook cumulative impacts, and trap decisions in binary “safe/unsafe” categories.A systems-first, tools-second approach can deliver faster, cheaper, and more effective decisions by prioritising simulation and systems understanding before developing regulatory tools forEnvironmental Risk Assessment (ERA). Horizon Europe’s PollinERA project demonstrates how this can work in practice: building a prototype One Systemworkflow with interoperable data and models for pollinator risk assessment; an approach that can be expanded to other environmental domains.

Abstract: Although biodiversity monitoring costs are widely cited as a constraint, there have been very few assessments of these costs and even fewer studies have assessed the potential benefits of this monitoring. Here, we synthesise available evidence, alongside a comprehensive assessment of the costs of proposed biodiversity monitoring to explore the relative costs, benefits risks and opportunities in biodiversity monitoring. We find that the costs of biodiversity monitoring, €0.5bn-€3.6bn/year, are greatly outweighed by the combined economic benefits and opportunities arising from the availability of co-ordinated, high-quality data, which are estimated to be >€25.2bn/year.

Abstract: The Gulf of Oristano Area, located on the central-western coast of Sardinia (Italy, Mediterranean Sea), is a highly diverse and ecologically valuable region. This area features a mosaic of habitats, supports rich biodiversity, and sustains traditional fishing practices. It is also protected under various international and EU conservation frameworks. However, despite its ecological importance, the Gulf Area faces growing pressures from human activities such as overfishing, eutrophication, habitat loss, and the introduction of non-native species. This study applies a bow-tie risk analysis framework to identify key drivers, pressures, and consequences associated with three central ecological events: species decline and loss, habitat change, and increased competition with non-native species. Stakeholder consultations and standardized classification systems inform the assessment, highlighting the interplay between legal fishing, tourism, aquaculture, pollution, and infrastructure development. The analysis identifies both prevention and mitigation measures, such as spatial planning, environmental monitoring, citizen science, and sustainable tourism and fisheries initiatives. While the environmental regulation of the Gulf of Oristano Area provides a basis for ecosystem protection, persistent challenges – such as enforcement, fragmented governance, and low stakeholder engagement – hinder effectiveness. To ensure ecological integrity and socio-economic resilience in the central-western Sardinian coast, this study underscores the need for strengthened integrated coastal zone management, alignment with EU strategies, and investment in adaptive and participatory conservation approaches.

Abstract: Defined as the benefits derived from nature to humans, the Ecosystem Services (ES) concept clarifies how ecosystems contribute to human well-being. Despite its relevance, integrating this concept into decision-making processes remains a challenge. Participatory approaches have proven crucial in developing mechanisms for managing, conserving, sustainably using and valuing ES. This work aimed to analyse the perceptions of Portuguese Biosphere Reserves’ (BR) managers regarding the ES provided by these territories through a participatory workshop. During the workshop, each participant specified the most relevant ES provided by the BR. The study identified three key ES: "Cultivated terrestrial plants (including fungi, algae) grown for nutritional purposes", "Characteristics of living systems that enable scientific investigation or the creation of traditional ecological knowledge" and "Characteristics of living systems that enable education and training". Additionally, participants discussed perceived threats, opportunities and potential solutions to enhance the value of these key ES in these areas. "Climate change" and "Pollution" were identified as the most significant threats, while "Climate adaptation", "Quality of life" and "Sustainable agriculture" emerged as the main opportunities. Solutions to address threats and maximise opportunities include the establishment of a closer, systematic and articulated relationship within BR to promote sustainability and resilience. Overall, the workshop was positively evaluated and deemed productive. It was also considered a powerful tool to foster collaboration towards a more holistic promotion of BR' sustainable governance, benefitting the environment, communities and the economy.

Abstract: A key goal of the EU Biodiversity Strategy for 2030 is the design of a connected Trans European Nature Network (TEN-N), that helps to build a coherent and resilient network of protected areas across Europe. The TEN-N will need to consider and integrate societal perspectives on future biodiversity protection in Europe, accounting for multiple values and perspectives of nature. The NaturaConnect project, through a process of co-design with stakeholders, is developing narratives on future nature protection in Europe using the Nature Futures Framework (NFF). In this framework. three value perspectives of nature are presented at each corner of a triangle: Nature for Nature, Nature as Culture, and Nature for Society. By using this framework, NaturaConnect aligns with global efforts on scenario development auspicated by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). This report outlines the development of scenario narratives for Europe of the NaturaConnect project. The development of the narratives considered the global and European policy context as a starting point, and included a stakeholder engagement process conducted to elicit stakeholders' preferences and visions in relation to future nature conservation and management in Europe. These narratives present contrasting perspectives and priorities for seven themes: Protected areas, Connectivity and Restoration, Forestry, Freshwater ecosystems, Urban system, Agriculture, Energy. These topics are key to building a more positive future for nature and people. Besides specificities for each narrative, we also identify commonalities across the three perspectives, including macroeconomic trend assumptions, biodiversity strategic goals of the European Union and shared solutions that are necessary to achieve any positive nature future.

Abstract: Bird populations respond rapidly to environmental change making them excellent ecological indicators. Climate shifts advance migration, causing mismatches in breeding and resources. Understanding these changes is crucial to monitor the state of environment. Citizen science offers vast potential to collect biodiversity data. We outline a project that combines citizen science with AI-based bird sound classification. The mobile app records bird vocalizations that are classified by AI and stored for re-analysis. Also, it shows a shared observation board that visualizes collective classifications. By merging long-term monitoring and modern citizen science, this project harnesses both approaches’ strengths for comprehensive bird population monitoring.

Abstract: The paper focuses on the technical workflow description of EOSC Future’s Science Project 9 'Climate Neutral and Smart Cities', using reputable data sources such as the European Social Survey (ESS), the European Environmental Agency (EEA), and Copernicus ERA5.A significant contribution of this project to the European Open Science Cloud (EOSC) is its demonstration of cross-domain data integration using the DDI-CDI metadata standard. This serves as a practical example of how the DDI-CDI Process model can offer a standardised methodology for detailing integration processes, thereby ensuring clarity for researchers dealing with integrated data and computed variables.The paper outlines the key elements of the CDI-Process model selected for this approach, which includes around 10 classes such as 'Activity,' 'Step,' and 'Parameter.' These classes form the structural framework for the data integration steps.Additionally, a tool developed under the project visualises the entire workflow as outlined in the CDI workflow description

Abstract: Knowledge of how personal experience with climate and air quality influence personal attitudes, concerns, and actions about environmental issues is increasingly important. A solid foundation for such studies is to combine interview or survey data on respondents’ attitudes and beliefs with indices created from independent meteorological or environmental monitoring data matched to the respondents location.In this project,  indicators of climate and air pollution were integrated with data from the European Social Survey for a selection of large European urban regions. A prototype provenance description application was also developed for describing the workflow for creating indicators and integrating data.Our main focus was on creating indicators that represent regional anomalies in local air quality and weather for a range of time windows up-to-and-including the dates of the interviews. The goal is to facilitate investigation of relationships between urban citizen’s attitudes and behaviors as represented in the survey responses and the conditions in their local environment.

Abstract: The main objective of the Science Project (SP) Climate Neutral and Smart Cities is to demonstrate that environmental data and data about people’s attitudes, behavior and involvement can be combined for social, political and scientific analysis. In the project, scientists from the Social Sciences & Humanities Open Cloud (SSHOC) and Environmental Research Infrastructures (ENVRI) community work together with the aim of producing new and useful outputs for the benefit of the research community, such as indicators related to environmental indices, and methods and workflows for computing them. The environmental variables will be integrated with data from the European Social Survey for a selection of big European city regions. Data and metadata from the project will be accessible through a new prototype application that will be made available as an exploratory “labs” service from the European Open Science Cloud (EOSC) Portal and the EOSC Marketplace. This will allow easy access to cross-domain data for scientific analysis and their provenance, as well as to other deliverables from the project.

Abstract: Observations are key to understand the drivers of biodiversity loss, and the impacts on ecosystem services and ultimately on people. Many EU policies and initiatives demand unbiased, integrated and regularly updated biodiversity and ecosystem service data. However, efforts to monitor biodiversity are spatially and temporally fragmented, taxonomically biased, and lack integration in Europe. EuropaBON aims to bridge this gap by designing an EU-wide framework for monitoring biodiversity and ecosystem services. EuropaBON harnesses the power of modelling essential variables to integrate different reporting streams, data sources, and monitoring schemes. These essential variables provide consistent knowledge about multiple dimensions of biodiversity change across space and time. They can then be analyzed and synthesized to support decision-making at different spatial scales, from the sub-national to the European scale, through the production of indicators and scenarios. To develop essential biodiversity and ecosystem variables workflows that are policy relevant, EuropaBON is built around stakeholder engagement and knowledge exchange (WP2). EuropaBON will work with stakeholders to identify user and policy needs for biodiversity monitoring and investigate the feasibility of setting up a center to coordinate monitoring activities across Europe (WP2). Together with stakeholders, EuropaBON will assess current monitoring efforts to identify gaps, data and workflow bottlenecks, and analyse cost-effectiveness of different schemes (WP3). This will be used to co-design improved monitoring schemes using novel technologies to become more representative temporally, spatially and taxonomically, delivering multiple benefits to users and society (WP4). Finally, EuropaBON will demonstrate in a set of showcases how workflows tailored to the Birds Directive, Habitats Directive, Water Framework Directive, Climate and Restoration Policy, and the Bioeconomy Strategy, can be implemented (WP5).

Abstract: Municipal solid waste management (MSWM) has become one of the most pressing environmental issues in South Asian cities, the more so as it is closely linked to drinking water quality, sanitation and human health affecting mostly the urban poor, as well as to global climate change. Looking at recent governance initiatives in three South Asian cities developed in the wake of natural or human-induced crises, the project will focus on how to render MSWM improvements politically feasible and socially acceptable, which is a pre-requisites for functioning SWM systems, and thus for (environmental and social) sustainability more generally. The goal of this project, therefore, is to identify, analyze and promote the political and sociocultural processes that are necessary to enable the functioning of MSWM systems. In particular, alternative practices and systems are promoted, whereby institutional hierarchies are decentralized, favoring horizontal accountabilities and whereby waste chains are shortened and transformed into closed loops implying a more circular waste economy in which both environmental and local livelihood benefits would accrue. The project puts emphasis on mutual learning through horizontal South-South partnerships between local authorities, civil society actors and researchers across South Asia.

Abstract: FluorRAS will develop a sensor that can save recycled fish farms 30% per year in water and energy consumption for water treatment, as well as optimize nitrogen removal. The sensor will be developed in a partnership between engineers (Krüger A / S) and researchers (DTU), and the product will be made available to the entire sector through Danish Aquaculture. Global aquaculture production is expected to double within the next 15 years. Recycling technology has a great potential for supporting environmentally and economically sustainable production. However, the technology has some challenges in balancing both the maintenance of necessary water quality and water treatment costs. Loss of production due to poor water quality is expensive and can be avoided with correct sensor systems. Accumulation of dissolved organic matter and nutrients in the water reduce the effectiveness of UV treatment, is a source of nutrition for opportunistic pathogens, and reduces the effectiveness of the biofilter's removing ammonia. Modern recycling systems are therefore dependent on a network of online sensors that monitor and respond to changes in water quality, but currently there is a need for a sensor to monitor the accumulation of organic matter. FluoRAS aims to fill this gap in technology by developing an online fluorescence sensor. The sensor is based on non-destructive, online optical technology that does not require chemicals and can run continuously.

Abstract: The protection, preservation and restoration of aquatic ecosystems and their functions are of global importance. For European states it became legally binding mainly through the EU-Water Framework Directive (WFD). In order to assess the ecological status of a given water body, aquatic biodiversity data are obtained and compared to a reference water body. The quantified mismatch obtained determines the extent of potential management actions. The current approach to biodiversity assessment is based on morpho-taxonomy. This approach has many drawbacks such as being time consuming, limited in temporal and spatial resolution, and error-prone due to the varying individual taxonomic expertise of the analysts. Novel genomic tools can overcome many of the aforementioned problems and could complement or even replace traditional bioassessment. Yet, a plethora of approaches are independently developed in different institutions, thereby hampering any concerted routine application. The goal of this Action is to nucleate a group of researchers across disciplines with the task to identify gold-standard genomic tools and novel eco-genomic indices for routine application in biodiversity assessments of European fresh- and marine water bodies. Furthermore, DNAqua-Net will provide a platform for training of the next generation of European researchers preparing them for the new technologies. Jointly with water managers, politicians, and other stakeholders, the group will develop a conceptual framework for the standard application of eco-genomic tools as part of legally binding assessments.

Abstract: This paper is an example to visualize bibliometric data to extract paper’s topics and their citation relation. It is very important to evaluate the number of documents, the intensity of the paper’s topic, and the relationship between papers. The output can be used to pinpoint suitable research topic. We began with 246 papers, gathered from Google Scholar, Crossref, and Scopus database. We narrowed them down to 70 papers based on language, relevance, pdf availability, and metadata completeness. Open source tools, Vosviewer, Zotero-PaperMachine plugin, were used to visualize the existing reference database. The following paper gives an illustration that a brief bibliometric analysis could assist a researcher to determine our research path. It gives us a glimpse of research landscape in Jakarta area. Therefore for deeper analysis, we will focus our literature review on groundwater and surface water interactions.
