The climate crisis and the nutrition crisis are intertwined
Climate change is causing more frequent and severe extreme weather events, shifting weather patterns, and altering food systems—trends that will continue to worsen. There is strong evidence that actions to mitigate or adapt to climate change can also improve nutrition, benefitting both climate and nutrition agendas. Yet, these two crises are often treated in isolation, limiting the impact of policies and investments in both areas. Both climate change and malnutrition share common drivers and consequences, making it essential to align solutions.
Evidence for interventions with dual nutrition and climate benefits
ST4N led the development of an interactive Evidence and Gap Map (EGM) of interventions to address the intertwined issues of climate change and malnutrition. This EGM presents the results of a systematic review of the evidence on multi-sectoral interventions that have demonstrated benefits for climate change (through climate mitigation or adaptation) and nutrition (including food security, diets, all forms of malnutrition, and diet-related non-communicable diseases)..
Policy brief and call to action
ST4N published a policy brief and Call to Action in February 2025 that examines the crucial relationship between climate change and nutrition. The brief identifies policy pathways that can simultaneously address climate adaptation and improve nutrition outcomes, particularly for vulnerable populations facing climate-related shocks.
While further research will help refine context-specific solutions, the policy brief’s recommendations provide immediate actions that can be taken now to protect vulnerable populations while addressing both climate and nutrition challenges.
Paris Nutrition for Growth (N4G) Summit
ST4N, together with GAIN, the Initiative on Climate Change and Nutrition (I-CAN), and the International Food Policy Research Institute (IFPRI), hosted a N4G Paris side event titled at the Civil Society Pavilion on 24 March 2025. Experts, policymakers, and funders gathered to explore the critical intersection of climate change and nutrition, with recommendations from the ST4N policy brief serving as a key component of the policy discussions.

The policy recommendations were presented at the I-CAN Roundtable Dialogue on February 5, 2025, organized by the Food and Agriculture Organization of the United Nations (FAO), GAIN, the Hospital for Sick Children, Toronto (SickKids), and the Government of France.
Additionally, in June 2024, Dr. Saskia Osendarp, Executive Director of the Micronutrient Forum, was invited by FAO to deliver a keynote address at Rome Nutrition Week, where she presented evidence on climate-nutrition connections within the context of food systems
