Develop collection, design, incentives, maintenance, and community-governance solutions that prevent drains from becoming chronic flood and disease hazards.

Create systems to track quality, environmental impact, labor conditions, and price integrity for sand, cement, steel, timber, and aggregates.

Develop mechanisms that address mine-level income, safety, child labor, local consent, and environmental damage rather than relying only on paperwork audits.

Develop systems that reduce child labor, conflict finance, and environmental harm while allowing artisanal miners to participate in formal markets.

Create age-appropriate programs that build emotional skills, peer support, referral pathways, and teacher capacity while respecting local culture.

Develop affordable lab equipment, experimental protocols, and digital interfaces that enable meaningful participation in science education for disabled learners.

Develop portable, durable water-treatment and storage systems aligned with mobile communities' routes, governance structures, and environmental constraints.

Build robust sensors that can alert utilities and communities to microbial contamination before outbreaks occur, even in turbid and intermittently supplied networks.

Establish evidence-based tools and public-health interventions for repeated smoke exposure, especially among children, older adults, and outdoor workers.

Develop accessible monitoring for silica dust exposure and early lung damage among artisanal miners and construction workers who lack occupational health coverage.

Build low-cost metagenomic and biosensor systems that identify emerging resistance genes in sewage networks early enough for hospitals and public-health agencies to alter treatment protocols.

Achieving early warning systems for social unrest linked to climate and resource stress 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.

Achieving systems ensuring the safety and reliability of AI systems used in critical infrastructure control 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 solutions for providing high-quality mental health care in primary care and community settings 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 early childhood development programs proven effective at national scale under fiscal constraint 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.

Achieving methods for restoring the carbon sequestration capacity of terrestrial and coastal ecosystems 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.

Achieving privacy-preserving detection of coordinated platform influence operations 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.

Achieving interventions that improve mental health and social cohesion in rapidly urbanizing populations 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 psychological first-aid and mental health systems scalable after mass trauma 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 self-sensing concrete reporting stress chloride and remaining life 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.
