Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Many consultation processes collect comments but provide no traceable response or rationale. Structured argument maps, versioned policy records, and privacy-aware participation analytics could improve accountability without reducing deliberation to popularity. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with coordinate uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Materials may be valuable but poorly documented, contaminated, or unavailable at the needed time. Standardized audits, uncertainty-aware marketplaces, and logistics coordination could make reuse competitive with disposal.

Mathematical modeling can help with measure uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Competence is often real but invisible to employers because certificates measure course completion rather than performance. Practical assessments, portable evidence, and trusted local validators could improve matching without forcing workers into expensive retraining. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with allocate uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Maps rarely capture broken lifts, blocked sidewalks, steep surfaces, or staff-dependent access. Community sensing plus uncertainty-aware routing could produce useful guidance while clearly communicating confidence and risk. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with forecast uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Small teams frequently lack stable repositories, metadata discipline, and affordable compute for preservation. Incentives for reproducible packaging, federated archives, and low-cost reruns could strengthen the reliability of applied science. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with verify uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Digitization can preserve technique while also enabling unauthorized imitation or commercial appropriation. Consent-aware archives, provenance systems, and community licensing models could protect both cultural continuity and creator income.

Germany has expanding agricultural frontiers bordering wildlife habitat where novel pathogens can jump species, but there is no routine, affordable genomic surveillance at these interfaces to catch spillover before human transmission begins.

By the 2030s and 2040s, extreme heat and shifting mosquito ranges will expand malaria, dengue, and other infections into new regions. Heat-health early-warning systems and climate-sensitive disease-modelling platforms must be deployed.
