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.

Some UN peacekeeping operations have run for so long that local governments and populations start questioning whether they're actually achieving anything anymore. Without clear exit criteria, missions risk becoming permanent without ever solving the underlying conflict.

Voting power at bodies like the IMF still roughly reflects the economic order from decades ago, giving less voice to countries that now represent a huge share of the world's population. This mismatch fuels distrust in the fairness of global rule-making.
