Nexus25 SIPRI Conference Workshop: Leader or Left Behind? The EU in a Euro-Mediterranean Polycrisis

By Siena Cicarelli, Luca Cinciripini, and Chiara Scissa

From May 12-14, the Nexus25 team attended the 2025 Stockholm Forum on Peace and Development. This year’s forum focused on “Rethinking Peace and the Future of Security,” with sessions dedicated to resolving the Israel-Palestine conflict, the ongoing humanitarian crisis in Sudan, enhancing youth engagement, avenues for dialogue in the Sahel region, advancing gender equity, and more. As part of these discussions, Nexus25 hosted a session entitled “Leader or Left Behind? The EU in a Euro-Mediterranean Polycrisis,” a combined panel discussion and scenario exercise focused on the EU’s response to converging risks in its  immediate neighborhood. 

Migration, insecurity, and climate change have left the Euro-Mediterranean region (EU and MENA states in the Mediterranean Basin) in a polycrisis – just as the United States and Europe slash foreign aid budgets. Crucially, projections from the World Bank that MENA countries will host the world’s largest proportion of internal climate migrants pose a major challenge for a region already characterized by armed conflicts, escalating political tensions, and instability. In this context, this session explored policy shifts needed for a more resilient EU, how to manage risk pathways, and areas for expanded partnerships in this new geopolitical environment. 

After hearing from regional experts including Dr. Alaa Tartir (SIPRI), Dr. Beatrice Mosello (adelphi), and Dr. Chiara Scissa (IAI), session participants engaged in a 2030 backcasting exercise to challenge their underlying assumptions about the complex crises to come. This exercise identified several urgent policy challenges for the EU, including the management of  food production and waste, developing a cohesive geo-economic approach, anticipating water  scarcity, and managing an aging population. 

In light of the panel discussion and backcasting exercise, key takeaways from the session included:

Overall, the panel discussion and scenario exercise emphasized that as the United States steps back from international development and humanitarian aid, now is the time for the EU to become “not just a payer, but a player” in the field. Long-term resilience requires not just  financial contributions, but better policies for all aspects of the nexus, including climate change, food security, demographic shifts, and migration.
