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.

Resistance to insecticides and antimalarial drugs is rising, and many rural clinics lack rapid diagnostic tools. Better low-cost diagnostics, vaccines with longer efficacy, and resistance-tracking data platforms are urgently needed.

Over 80% of workers in countries like India, Bangladesh, and Nepal operate within informal economies without access to pensions, disability insurance, or minimum wage guarantees. Traditional bureaucratic tax and welfare systems fail to track or protect these transient and cash-reliant populations during economic shocks.
