Addressing the joint food security and climate challenges using the economist toolbox: an illustration with the FAO Global Roadmap to achieve SDG2 without breaching 1.5C.

In the age of polycrisis (climate change, conflicts, economic shocks, etc.), the FAO Global Roadmap has developed a framework of how agrifood systems should address food security and nutrition needs and facilitate many actions aligned with mitigation, adaptation, and resilience objectives under the larger umbrella of climate action.The FAO Global Roadmap is both a theory and instrument of change to guarantee we can deliver good food for all, today and tomorrow. The FAO Global Roadmap aims to bring a constructive, solution-oriented approach, showing that without efficient, sustainable and inclusive transformation it will not be possible to address these goals. To achieve such challenges, and convince all stakeholders, policy makers, the private sector and the civil society to take action, mobilizing state-of-the-art tools and evidence is an absolute need. Hopefully, economic sciences, when combined with natural sciences, provide key tools to achieve these objectives. During the presentation, I will present the FAO Global Roadmap and identify the ranges of methods and instruments that are needed to support such effort at the macro and micro level: applied General Equilibrium modelling, household level analysis, RCTs, political economic, systematic reviews.;
