The proactive sustainable management of scarce water across vulnerable agricultural areas of South Europe is a timely issue of major importance, especially under the recent challenges affecting complex water systems. The Basin District of Thessaly, Greece’s driest rural region, has a long history of multiple issues of an environmental, planning, economic or administrative nature, as well as a history of conflict. For the first time, the region’s key-stakeholders, including scientists and policymakers, participated in tactical meetings during the 19-month project “Water For Tomorrow”. The goal was to establish a common and holistic understanding of the problems, assess the lessons learned from the failures of the past and co-develop a list of policy recommendations, placing them in the broader context of sustainability. These refer to enhanced and transparent information, data, accountability, cooperation/communication among authorities and stakeholders, capacity building, new technologies and modernization of current practices, reasonable demand and supply management, flexible renewable energy portfolios and circular approaches, among others. This work has significant implications for the integrated water resources management of similar south-European cases, including the Third-Cycle of the River Basin Management Plans and the International Sustainability Agendas.

The phenomena of climate change transcend all national and regional boundaries. To address this complex challenge, we must determine the areas of the country of interest, in this case, Greece, that have been most adversely affected by climate. Greece is surrounded by water, and a significant part of its GDP is derived from the marine and maritime industries, including tourism. Since the start of the IntelComp project, a Preparatory Living Lab (PLL) has been planned and delivered, feeding into the development of the IntelComp platform and the Living Lab on Climate Change Adaptation. The study's results lead to the conclusion that one of the most important challenges in tackling climate change is the decarbonisation challenge, specifically the shift to renewable energy sources and the investments that must be made. Several EU and national policy frameworks, including the European Green Deal, the Climate Law, the National Long-term Strategy for 2050 (on the Climate and Energy), highlight the decarbonisation as one of the major challenges in the climate change pledge. This will be the primary subject of the IntelComp climate change case study. PLLs also led to the identification of policy questions and useful data sources to aid the IntelComp project's launch. While previous research on co-production has primarily focused on involving citizens through public participation processes in order to gain their support, trust, and insights in structured decision-making processes, our approach opens a new channel for incorporating external knowledge into problem-solving processes. The IntelComp project will aid in policy development by providing pertinent tools co-developed with the final users that will provide insights and analysis in the field of STI (Science, Technology, Innovation) encompassing all of the Energy areas mentioned above.

Purpose: Storytelling through virtual reality (VR) combines the strengths of cutting-edge technology with traditional informational campaigns. As a tool for climate change mitigation, VR has been shown to educate individuals and stimulate both emotional and cognitive responses that promote pro-environmental behavior. This paper aims to investigate whether these benefits extend to the field of green investing through an experiment conducted with a sample of small business entrepreneurs.Design/methodology/approach: The experimental design involved making choices between bonds varying in maturity dates, annual interest and environmental classification (regular versus green). To identify potential impacts of the immersive experience on investment decisions, these choices were made both before and after exposure to VR videos illustrating the devastating effects of climate change. A multiple price list was employed to elicit subjects' risk preferences, enabling the joint estimation of the treatment effect and the risk and time preference parameters. Findings: The findings indicate that, when risk and time preference parameters are controlled for, a VR experience can nudge toward green investment choices. This effect is more profound among those who already exhibit a greater propensity to opt for green investments.Originality/value: Previous research shows that negative emotions, such as guilt, affect pro-environmental intentions, as well as actions, while message vividness through immersive experiences is effective in nudging greener behavior. Since analogous results in the framework of financial investments are not currently available, this paper seeks to test whether VR videos depicting the adverse effects of climate change can generate negative emotions associated with experiencing these effects and make them salient in subsequent investment decisions made by small business entrepreneurs.

The complex interrelations between ocean governance, climate change, and innovation create both challenges and opportunities for sustainable development in the Black Sea region. The blue economy— encompassing fisheries, tourism, ports, shipping, and marine transport—plays a crucial role in regional prosperity but faces mounting pressures from overfishing, pollution, geopolitical instability, and the low capacity for technological and institutional adaptation. The EU‐funded projects DOORS and BRIDGE‐BS address these challenges through participatory, system‐based approaches that engage stakeholders from across the quadruple helix (academia, industry, government, and civil society). While DOORS sought to identify policy and innovation gaps at the regional level through multi‐actor forums, BRIDGE‐BS explored future pathways for a sustainable and resilient blue economy using living labs and participatory foresight. Together, they reveal a persistent disconnect between local implementation capacity and national policy ambition, as local actors often remain locked in existing practices and lack the skills and resources to embrace emerging sectors. The results indicate that the sectors have similar goals, such as capture fisheries, marine and coastal tourism, ports and shipping, and marine transport. They also face similar problems, such as weak law enforcement, fragmented governance, bureaucratic inefficiencies, and a lack of new technology. The study underscores the value of participatory multi‐actor engagement in bridging the science–policy practice gap, supporting skills development, and co‐designing actionable pathways toward climate‐resilient ocean governance. Lessons from the Black Sea demonstrate that integrating systems innovation, participatory governance, and capacity building can inform broader regional and global initiatives under the EU Mission: Restore our Ocean and Waters, the UN Ocean Decade, and the SDGs, providing a transferable model for advancing sustainable blue transitions in politically sensitive marine regions.
