Rural clinics in Kenya lose a significant share of temperature-sensitive vaccines to cold-chain breaks between district depots and final delivery points, driven by unreliable electricity, sparse refrigerated transport, and thin logistics staffing.

Unregulated industrial discharge into river basins near Indonesia is degrading downstream drinking water quality, but enforcement is hampered by a lack of low-cost, continuous water-quality sensors.

A persistent gap exists in realizing practical, scalable solutions for therapeutics targeting the shared biological pathways underlying multiple chronic diseases. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.

The absence of robust, context-adapted solutions for governance models for shared management of critical mineral resources 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 designs for energy systems that integrate high shares of variable renewables with high reliability 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 models for shared management of transboundary aquifers and rivers 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.
