Current approaches to pathways for transitioning coal-dependent communities to sustainable and dignified livelihoods 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 solutions for providing high-quality primary healthcare in remote and underserved 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.

Current approaches to highly selective multi-tissue senolytic therapeutics 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 pathways for rapidly scaling regenerative agriculture without compromising yields 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.

Current approaches to AI tools that accelerate scientific discovery while remaining transparent and auditable 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.

Current approaches to technologies for the selective recovery of valuable materials from complex waste streams 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.

Informal minibus and paratransit systems in Germany carry the majority of urban commuters but operate without route optimization, safety standards, or integration with formal transit planning.

Achieving pathways for achieving high levels of energy efficiency in existing building stocks 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.

Despite recognition of its importance, reliable methods for education systems that equip citizens to evaluate scientific claims in a high-misinformation environment 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.

Coastal aquifers in Fiji are increasingly contaminated by saltwater intrusion driven by overextraction and rising sea levels, threatening long-term drinking water and irrigation supply.

Despite recognition of its importance, reliable methods for biotechnologies enabling the rapid production of medical countermeasures against emerging pathogens 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 architectural innovations that make high-density living compatible with climate resilience and well-being 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.

Organic waste makes up a large share of landfilled municipal waste in Papua New Guinea, generating methane emissions that could be avoided with accessible composting infrastructure.

Coastal communities in United States face progressive land loss from sea-level rise, but planned relocation efforts lack frameworks for preserving livelihoods, land rights, and cultural continuity during resettlement.

Despite recognition of its importance, reliable methods for methods for assessing the social equity impacts of different climate mitigation and adaptation strategies 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 permafrost carbon abrupt-release early warning models 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.

Current approaches to non-invasive continuous monitoring of multiple chronic disease biomarkers 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.

A large share of rural handpumps and boreholes in Kenya sit broken at any given time because there is no real-time monitoring system to alert maintenance crews before communities revert to unsafe water sources.

Despite recognition of its importance, reliable methods for cognitive prosthetics augmenting working memory for specific learning profiles 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 real-time acoustic-optical networks tracking insect biomass decline 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.
