Staple crops grown in Nigeria are increasingly vulnerable to heat stress and shifting rainfall patterns, and locally adapted resilient varieties take years to breed and distribute through existing seed systems.

Achieving methods for assessing and mitigating the impacts of climate change on cultural heritage sites at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

The absence of robust, context-adapted solutions for biotechnologies for engineering crops with enhanced nutritional profiles under climate stress creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Current approaches to nature-based solutions for urban biodiversity that also provide cooling and flood benefits either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

The absence of robust, context-adapted solutions for mechanisms for aligning agricultural subsidies and policies with climate and biodiversity goals creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Current approaches to methods for quantifying the full costs of inaction on climate change biodiversity loss and pollution either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.
