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.

The problem of high rates of early school leaving continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

The ability to freeze aging in specific organs or features while others continue creates new forms of body modification and potential health imbalance. The problem is ensuring medical safety, informed consent, and equitable access without enabling permanent physical stratification.

continued high burden of malaria remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Future progress on human development and planetary health depends on solving continued rise in global average temperatures. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

Many connected devices become permanently vulnerable once their manufacturer stops issuing security updates, yet the devices often remain in active use for years afterward. A sustainable way to keep abandoned devices secure remains unresolved.

Robocalls and spam calls continue to reach users despite various blocking technologies, partly because scammers can spoof caller information and operate across international boundaries where enforcement is inconsistent. A fully effective, universal solution remains unbuilt.
