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.

Hurricanes and tornadoes can still shift path or intensity with little warning, leaving communities scrambling to evacuate. More precise, longer-range forecasting could save lives and billions in property damage every year.

Growing crops in space or on other planets means dealing with low gravity, radiation, and limited water and soil. Without solving this, any permanent settlement beyond Earth stays dependent on costly resupply missions.

Outside Earth's magnetic field, cosmic radiation raises cancer risk and can damage the brain and body over time. This is one of the biggest blockers to sending humans to Mars safely.

Current approaches to real-time monitoring and response systems for industrial chemical and oil spill events 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.

The absence of robust, context-adapted solutions for education approaches that build the capacity for systems thinking and long-term decision making 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.

Despite recognition of its importance, reliable methods for institutional designs that reduce the influence of short-term interests on long-term policy 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.
