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.

Bacteria are evolving resistance faster than pharmaceutical companies are creating new antibiotics to fight them. Left unresolved, common infections could become deadly again within a few decades.

Many fast-growing cities in arid regions are outpacing the water systems built to serve them, leading to shortages and rationing. Solving this needs both new infrastructure and smarter long-term water planning.

Many major rivers and aquifers are being pumped or diverted faster than rainfall can replenish them, threatening long-term water security. Without better management, some regions may simply run out of accessible fresh water.

Methane is a far more potent greenhouse gas than carbon dioxide in the short term, and much of it leaks unnoticed from pipelines and wells. Better detection and faster repairs could meaningfully slow near-term warming.

Coral bleaching events are becoming more frequent as ocean temperatures rise, and restoration efforts are still small and slow. Without faster recovery methods, many reef ecosystems may not survive this century.

Modern farming often strips soil of nutrients faster than nature can replace them, threatening long-term food production. A farming method that restores rather than depletes soil could secure food supply for generations.

For decades, computer chips got faster mainly by shrinking transistors, but they're now near the smallest physically possible size. Finding a new way to keep computing power growing is an open engineering problem.
