Migrant laborers leaving Fiji for work abroad are frequently subject to recruitment fraud and exploitative contract terms due to weak oversight of labor recruitment agencies.

Despite recognition of its importance, reliable methods for governance models for managing the risks and benefits of geoengineering research and potential deployment 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.

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.

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 institutional designs that reduce the risk of nuclear escalation in multipolar crises. 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.

Despite recognition of its importance, reliable methods for mechanisms aligning private R&D incentives with global health and climate priorities 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.

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.

Despite recognition of its importance, reliable methods for biotechnologies for engineering microorganisms that convert atmospheric CO2 into useful products 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 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.

Current approaches to institutional innovations reducing the lag between scientific evidence and policy action 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.

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.

Despite recognition of its importance, reliable methods for ambient methane oxidation catalysts for livestock regions 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.

Despite recognition of its importance, reliable methods for deliberation systems reducing affective polarization while preserving contestation 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 interventions that reduce the prevalence of violence against women and children 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.

Rivers feeding into coastal waters near Democratic Republic of Congo carry substantial plastic waste from inland cities, and municipal waste management systems lack the capacity to intercept it before it reaches the ocean.

Despite recognition of its importance, reliable methods for participatory budgeting designs resistant to elite and algorithmic capture 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.

Despite recognition of its importance, reliable methods for affordable and scalable solutions for the prevention of the major causes of premature mortality 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.

Despite recognition of its importance, reliable methods for solutions for managing the growing volumes of electronic and battery waste 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.

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.
