Transdisciplinary Approaches to Co-Construct a Resilient Future

Marine Heatwave Response Management Workshop, March 28, 2025
On March 28, 2025, IRD in Nouméa hosted the first collective intelligence workshop as part of the MaHeWa project, dedicated to managing marine heatwaves in New Caledonia. The main objective of the day was to address two key questions: what should be done when an imminent marine heatwave is announced? and what are the seven priority themes to include in a collective strategy? More specifically, the workshop aimed to: inform stakeholders about marine heatwaves and their impacts, identify actions to implement, determine barriers and levers for intervention, and co-develop a management unit and a tailored communication plan.
A Second Workshop to Co-Design Responses to Marine Heatwaves in French Polynesia

As part of the CCTs of the MaHeWa project—whose objective is to co-construct crisis-response strategies and long-term adaptation solutions through transdisciplinary approaches—a second workshop was held on 21 October 2025 at the Ifremer center in Vairao. The meeting brought together around thirty participants, including municipal representatives, environmental associations, staff from the Marine Resources Department, representatives of the Interministerial Delegation for Climate and Sustainable Development, and several researchers involved in the project. The workshop aimed to discuss in concrete terms the effects of ocean heatwaves and the collective actions that could be developed to mitigate their impacts on ecosystems and human activities. A first workshop of this kind had already taken place in Nouméa, New Caledonia.
