Women in rural areas of Haiti often travel long distances for reproductive healthcare, and the shortage of trained providers leaves many without access to family planning or maternal care services.

A large share of primary school students in South Africa cannot read a simple sentence by the expected grade level, reflecting gaps in teacher training and curriculum pacing rather than school attendance alone.

Despite recognition of its importance, reliable methods for pathways for achieving high rates of energy efficiency and demand reduction in buildings and industry are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Achieving protocols for the rapid and equitable deployment of climate adaptation technologies 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.

Existing crop insurance schemes in Pakistan are financially unworkable for smallholder farmers due to high premiums, slow claims verification, and payout structures poorly matched to localized weather risk.

A persistent gap exists in realizing practical, scalable solutions for real-time systems for detecting and responding to the emergence of novel zoonotic 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 city-scale anthropogenic versus biogenic CO2 attribution networks 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.

Despite recognition of its importance, reliable methods for solutions for providing reliable digital connectivity in remote and disaster-affected areas are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

The absence of robust, context-adapted solutions for pathways for achieving universal access to clean cooking without locking in high emissions 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 mechanisms for aligning the incentives of financial institutions with climate and sustainability outcomes 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.

Farmers in Ukraine widely rely on diesel pumps for irrigation, and solar-powered alternatives remain financially out of reach without financing mechanisms tailored to seasonal farm income.

The absence of robust, context-adapted solutions for interventions that improve the nutritional quality of diets in low- and middle-income countries 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 nature-based solutions for landslide risk reduction on steep slopes in tropical regions 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.

Mobile money platforms widely used in Peru are frequent targets of SIM-swap and social engineering fraud, and current verification protocols are insufficient to prevent account takeovers.

Despite recognition of its importance, reliable methods for affordable methods for continuous monitoring of air and water quality in informal settlements are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

Dengue surveillance in Brazil is largely retrospective, relying on confirmed case counts reported weeks after transmission has already accelerated, rather than integrating mosquito density, rainfall, and mobility data into a forward-looking model.

The absence of robust, context-adapted solutions for low-cost genomic surveillance platforms for endemic and emerging pathogens 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 self-healing structural composites for marine cyclic loading 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.

Germany's aging population is outpacing the development of affordable elder care facilities and trained caregiving staff, leaving many families without support for elderly relatives.

A persistent gap exists in realizing practical, scalable solutions for governance models for ensuring the equitable distribution of benefits from AI and automation. 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.
