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.

Future progress on human development and planetary health depends on solving elderly people left without adequate care. 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.

Infants may receive temporary cognitive or motor skill packages that expire after a trial window, creating pressure to purchase permanent versions. The challenge is ensuring that basic developmental capacities remain freely available and that commercial skill layers do not become gatekeepers of opportunity.

When local weather can be bought in advance, wealthier areas may secure preferred conditions while poorer ones experience residual or adverse patterns. The challenge is creating equitable allocation mechanisms for atmospheric resources that do not deepen existing social divides or disrupt larger climate systems.

Vendors operate with thin margins and little historical data. Lightweight forecasting, shared cold storage, and cooperative purchasing could convert neighborhood-level signals into practical decisions without requiring enterprise software. The opportunity is intentionally human-scale: a cooperative, clinic, workshop, school, or municipal team could pilot it within one locality and measure outcomes before expanding. Mathematical modeling can help with allocate uncertainty, incentives, or resource constraints; entrepreneurship can turn a reliable workflow into a viable service.

Good firms can be rejected because financial statements lag reality or assets are hard to pledge. Cash-flow inference, purchase-order verification, and risk-sharing products could widen credit while limiting fraud and over-borrowing.
