The absence of robust, context-adapted solutions for methods for quantifying the biodiversity and carbon co-benefits of different restoration approaches 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.

Achieving designs for public spaces that promote social connection and mental well-being in dense cities 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.

Smallholder farmers in Myanmar lose a substantial share of harvested grain to pests, mold, and poor storage before it ever reaches market, largely due to the cost of hermetic storage technology.

The absence of robust, context-adapted solutions for methods for quantifying the full social and environmental costs of different mobility systems 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.

Millions of rural households in Bangladesh remain unconnected to the grid, and mini-grid and solar home system providers struggle with financing models that make service affordable while remaining commercially viable.

The absence of robust, context-adapted solutions for modular housing meeting simultaneous seismic flood and heat standards 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.

The absence of robust, context-adapted solutions for solutions for providing safe drinking water in regions with high natural or anthropogenic contamination 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.

The absence of robust, context-adapted solutions for interventions that reliably improve mental health outcomes at population scale 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.

The absence of robust, context-adapted solutions for governance frameworks for the ethical development and deployment of human enhancement technologies 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.

Design systems that remain usable for people with limited literacy, disability, low connectivity, language barriers, or insecure documentation. The challenge is especially acute in remote island communities, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

Create conservation and restoration approaches that protect biodiversity while sustaining the people whose food, income, and culture depend on those ecosystems. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

Develop practical data collection, modeling, public deliberation, and evaluation tools for decisions currently made with incomplete or inaccessible evidence. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

Create safe, economically viable collection, sorting, repair, reuse, and material-recovery systems suited to decentralized local markets. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

Develop enforceable, worker-centered protections for safety, pay, benefits, bargaining, and grievance resolution outside conventional employment. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.
