The absence of robust, context-adapted solutions for real-time systems for predicting and mitigating the cascading impacts of climate extremes 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 home-compostable polymers matching PET barrier performance 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.

Current approaches to biotechnologies for engineering plants that sequester more carbon in durable soil organic matter 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.

Affordable housing construction in Philippines is constrained by the high cost of imported cement and steel, while locally viable alternative materials remain underused due to lack of building code recognition.

Current approaches to governance models for ensuring the ethical development of advanced human-machine interfaces 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.

Infectious disease outbreaks near Vietnam's borders are frequently delayed in detection because neighboring health ministries use incompatible reporting systems and lack a shared, real-time data-sharing agreement.

Current approaches to methods for restoring the health of oceans and marine ecosystems under multiple stressors 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.

Achieving affordable and durable solutions for household air pollution in biomass-dependent regions 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.

Peri-urban areas surrounding major cities in United States have inconsistent internet access, limiting residents' access to remote work, telehealth, and digital financial services.

Current approaches to methods for restoring the ecological function of coral reefs under ongoing climate change 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.

Achieving methods for restoring the water quality and ecological function of urban rivers and lakes 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.

The absence of robust, context-adapted solutions for sensor networks and models for predicting urban flood risk at street-level resolution 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.

Public transit systems in Australia largely lack infrastructure accommodating wheelchair users and other mobility-impaired riders, effectively excluding them from affordable transportation.

A persistent gap exists in realizing practical, scalable solutions for therapeutics that reverse or halt the progression of major neurodegenerative 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.

Achieving materials enabling efficient direct conversion of sunlight to liquid fuels 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.

Current approaches to low-cost continuous metabolic monitors for resource-limited diabetes care 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 persistent gap exists in realizing practical, scalable solutions for systems ensuring the safety and reliability of autonomous vehicles in mixed traffic environments. 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.

Public procurement processes in Nigeria lack standardized open-data reporting, making it difficult for civil society and auditors to detect overpricing, collusion, or misallocation of public funds.

Current approaches to neutron-resistant fusion blanket and structural materials 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.

Achieving biotechnologies for engineering crops that require substantially less water and fertilizer 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.
