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 neutrality remaining hard to keep. 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.

platform companies keeping most of the value 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.

Dispensers that release water only after correct answers create barriers for children, visitors, and people with cognitive differences. The problem is providing free hydration without knowledge tests as gatekeepers.

Entrances that expand or contract according to digital invitation data can exclude people with disabilities or create real-time social filtering. The challenge is keeping physical thresholds inclusive regardless of digital status signals.

When the first person to capture an image of a cloud asserts property rights, the atmosphere itself becomes a contested resource. The problem is keeping the sky as a shared commons while still recognising legitimate creative or scientific claims on specific observations.

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.

Public services will increasingly depend on rapidly updated models and decision pipelines. The unresolved problem is keeping these systems lawful, understandable, and corrigible as they evolve faster than formal regulations. This becomes particularly difficult in informal settlements, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

Disasters can overwhelm budgets, insurance markets, and borrowing capacity long before adaptation completes. The challenge is designing fiscal rules, reserves, and mutual support systems that keep essential public services functioning. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Synthetic biology and AI-assisted design may create biological capabilities that are both socially valuable and potentially dangerous. The unresolved problem is building oversight that reduces misuse risk while keeping legitimate research open and productive. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.
