Event Summary: Nexus25 2025 UN Climate Week Roundtable
On September 24, 2025, the Nexus25 team convened a private roundtable discussion at this year’s NY Climate Week, focusing on how climate change, food security, and conflict are reshaping human mobility globally. Experts spanning multiple UN agencies, humanitarian organizations, private sector companies, research institutions, and more came together to discuss:
- How national authorities can properly mobilize domestic resources and engage in long-term planning across the climate mobility continuum;
- How policymakers can minimize the impact of divisive rhetoric surrounding migration and human mobility – and galvanize support for anticipatory action that helps people safely move or stay;
- Which upstream interventions are most effective in building partner capacity to handle internal displacement; and
- What new alliances and strategies at the multilateral level are required to manage increased human mobility.
A summary of the Nexus25 side event “Human Mobility At the Nexus of Climate, Food, and Conflict” can be found here.

The State of Human Mobility at the Nexus of Climate, Food, and Conflict
By Siena Cicarelli and Erin Sikorsky
Deep funding cuts and political shifts in the United States, along with other multilateral actors turning inward, have weakened investment in climate security and migration governance. At the same time, accelerating climate impacts are undermining crop yields, shifting growing seasons, and destabilizing food supply chains, especially in sub-Saharan Africa and South Asia. These pressures are fueling hunger, malnutrition, and displacement, with 64.3 million people internally displaced in food crisis contexts in 2023 and 123.2 million people forcibly displaced worldwide in 2024.
