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.

Wars, droughts, and shipping disruptions can send food prices soaring almost overnight, hitting poorer households hardest. A more resilient global food system could soften these shocks before they cause real hunger.

Despite regulation added after every major crash, financial systems keep finding new ways to become unstable. We still don't have a reliable way to prevent the next one before it happens.

A persistent gap exists in realizing practical, scalable solutions for governance frameworks for the ethical use of predictive analytics in criminal justice and social services. 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.

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.

Current approaches to real-time systems for predicting and mitigating the impacts of extreme precipitation 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.
