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 early warning systems that are missing 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.

Warnings often fail because people lack transport, trust, shelter, money, or authority to act. The unresolved problem is linking forecasts to pre-agreed decisions, resources, and responsibilities at local level. The solution must work with limited capital, intermittent services, and local maintenance capacity. The research opportunity is to define measurable success criteria, test the approach in realistic settings, identify failure modes, and create a pathway from prototype to accountable deployment.

A fabricated but realistic-seeming weather alert or disaster warning could spread panic or cause people to take unnecessary risky action before it's identified as false. Faster detection and correction systems for this kind of misinformation remain underdeveloped.

When one website's user database is breached, attackers often successfully reuse those same stolen credentials on other unrelated websites where people reused the same password. Preventing this cascade of breaches remains an ongoing security challenge despite widespread password reuse warnings.

Companies sometimes stop providing security patches for older but still commonly used software or devices, leaving users vulnerable without clear warning. Establishing consistent, enforced support timelines remains an unresolved industry practice.

When companies discontinue software or online services, users often lose access to their data or functionality with little warning or support for migrating elsewhere. Standardized, consumer-friendly transition processes remain largely absent from the industry.

People increasingly turn to AI chatbots for guidance on legal or financial questions, but these systems can provide plausible-sounding yet incorrect advice with no clear warning of their limitations. Better safeguards around this kind of high-stakes advice remain underdeveloped.

By the 2030s and 2040s, extreme heat and shifting mosquito ranges will expand malaria, dengue, and other infections into new regions. Heat-health early-warning systems and climate-sensitive disease-modelling platforms must be deployed.

Multiple overlapping shocks—from war in Ukraine and energy disruption to populist politics and institutional strain—are testing the resilience of European democracies. Builders can develop scenario-modeling and early-warning tools to help governments and investors navigate these risks.
