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 reforestation projects plant fast-growing single species rather than rebuilding complex, biodiverse forest ecosystems, which limits their true ecological value. Making these projects genuinely restorative rather than just visually green remains an unresolved challenge.

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.

A persistent gap exists in realizing practical, scalable solutions for systems ensuring the long-term stewardship of carbon dioxide removal projects. 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.

A persistent gap exists in realizing practical, scalable solutions for institutional arrangements that reduce corruption risk in large climate adaptation projects. 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.
