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.

Materials marketed as biodegradable may require industrial conditions unavailable in real waste systems or may fragment into harmful residues. Standards must distinguish genuine environmental benefit from misleading claims. 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.

The problem of companies claiming to be green but not 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.

AI-assisted work complicates ownership, credit, responsibility, and compensation. New systems must distinguish meaningful human contribution without rewarding superficial claims or enabling exploitation. 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.

Precipitation whose nutrient profile varies by corporate cloud ownership creates uneven agricultural and health outcomes. The challenge is ensuring that atmospheric water remains compositionally neutral regardless of commercial claims.

If parks close at night on the grounds that vegetation requires solitude, human access to green space is reduced. The problem is integrating genuine ecological rest requirements with the continuous human need for outdoor refuge and recreation.

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.

Claims about quantum advantage often depend on narrow benchmarks or idealized assumptions. The challenge is creating reproducible measurements that identify when quantum systems deliver meaningful benefits over classical alternatives. 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.

Digitizing land records can improve access while also enabling new forms of fraud, corruption, and system failure. The challenge is designing registry governance that protects ownership claims, customary rights, and dispute resolution over decades. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.

Companies can use AI to generate legal language that's technically accurate but deliberately obscures consumers' actual rights, making it harder to understand what protections truly apply. Improving genuine clarity in these documents remains unresolved.

AI-generated marketing content can sometimes make health claims about food or supplement products that aren't accurate or substantiated, and regulatory review hasn't fully adapted to this new content generation speed. Closing this gap remains an unresolved consumer protection issue.

Digital signatures can be technically valid while still being applied under coercion, fraud, or through compromised credentials, and current systems don't fully verify true signer intent. Closing this verification gap remains an unresolved legal-technical challenge.

Fraudulent insurance claims can now include AI-generated images of damage that never occurred, and current claims review processes aren't fully equipped to detect this kind of fabricated evidence. Closing this detection gap remains an unresolved challenge for insurers.

Insurance companies increasingly use AI to assess claims, but there's limited independent, scalable auditing to ensure these systems aren't unfairly denying or delaying valid claims. Building trustworthy oversight for this remains an unresolved regulatory and technical challenge.

AI systems can generate false information with the same fluent, confident tone as accurate information, making it hard for users to tell the difference without independently verifying every claim. Reducing this so-called hallucination problem remains a central AI research challenge.

This long-standing conjecture claims there's always at least one prime number between any two consecutive perfect squares, and while verified extensively by computer, no general proof exists. Solving it would sharpen our understanding of prime distribution.
