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.

Build affordable monitoring and response systems that identify local environmental threats before they become chronic public-health crises. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.
