New data streams highlight the low levels of access to climate finance by the most climate-vulnerable countries, which struggle with conflict and displacement and call for more effective financing mechanisms. While such measures are urgent, their effectiveness and impact depend on investments in capacity development and education. In exploring recent international policy trends in climate, conflict, and displacement, this article argues for greater attention to endogenous capacities and implementation of science-informed approaches. It highlights the key role academia and the education sector can play in addressing these gaps. In contexts where conflict and displacement are ongoing, and climate and insecurity jeopardize sustainability, this paper argues that strengthened capacities can represent a critical adaptation measure and a no-regrets investment opportunity.
