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 adaptation measures protect health, social stability, and ecosystems rather than producing direct revenue. New financial structures are needed for projects whose greatest value is avoiding losses that may never be visibly recorded. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

A seawall, air conditioner, reservoir, or drought-resistant crop can reduce one risk while increasing inequality, heat, debt, ecological damage, or downstream exposure. The challenge is evaluating full-system consequences before large investments are locked in. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

Modern software often relies on long chains of interconnected code packages, and a single broken or malicious update deep in that chain can cascade into failures across countless unrelated projects. Making this system more resilient remains an unresolved structural issue.
