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.

Resources like fresh water, fertile soil, and certain minerals are being used faster than they can replenish, yet markets often don't price this depletion accurately. Building this cost into economic decision-making remains largely unresolved.
