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.

As cities and suburbs expand, they often replace the wildflower meadows and natural habitats that pollinators depend on with lawns and pavement. Designing urban growth that preserves pollinator habitat remains inconsistently practiced.

Degraded peatlands release significant amounts of stored carbon, and restoring them to their natural, carbon-storing state requires careful, sustained management that many restoration projects don't achieve. Making this restoration reliably effective remains unresolved.
