Call for Sessions: Nature-based Solutions International Congress

Call for Session Proposals

At a time when profound and transformative change is urgently required to address the intertwined crises of climate change, biodiversity loss, and growing social inequalities, the Nature-based Solutions International Congress will position Paris as a global focal point for advancing Nature-based Solutions (NbS). From November 3 to 6, 2026, at Sorbonne University in Paris, France, the Congress will bring together researchers, policymakers, practitioners, urban leaders, businesses, investors, and civil society actors from around the world.

Conceived as a convergence space, the Congress aims to accelerate the global NbS agenda by fostering dialogue across science, governance, finance, and implementation. Supported by the French National Research Program on Nature-based Solutions (SOLU-BIOD), NetworkNature, UNP+, Biodiversa+ and Sorbonne University, it aims to create a decisive moment of alignment across science, governance, and implementation, strengthening synergies and amplifying the international impact of NbS.

As one of its core events, the Scientific Conference will mark a major milestone in advancing knowledge on Nature-based Solutions. It fills a critical gap by providing a dedicated forum for presenting and discussing fundamental, interdisciplinary, participatory, and action-oriented research, while fostering dialogue across disciplines and sectors.

To co-design this ambitious scientific program, the Congress is launching an International Call for Sessions, inviting the global NbS community to propose thematic sessions that reflect the diversity, innovation, and transformative potential of NbS research across continents.

Scope of the Call

We invite proposals for 2-hour sessions that address the multifaceted challenges of Nature-based Solutions across all ecosystems, sectors, and geographical scales.

Contributions may be theoretical, methodological, empirical, or practice-oriented, and are particularly encouraged to bridge perspectives and experiences across communities.

Indicative (non-exhaustive) themes include:

  • The role of genetic diversity and evolutionary potential for the effectiveness and resilience of NbS at different spatial and temporal scales.
  • The role of social processes, governance arrangements, and stakeholder dynamics in the success of Nature-based Solutions.
  • The evaluation of NbS performance, including ecological, social, and economic dimensions, and the mechanisms enabling their scaling-up and long-term sustainability;
  • Scenarios, models, and foresight approaches to anticipate NbS performance under climate change and other global change drivers;

Proposals addressing other NbS-related topics fully aligned with the Congress are equally welcome.

Proposers may request up to three sessions, justified by the scope and ambition of the topic.
