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.

Traditional credentials are too slow for rapidly changing technical work, while unverified short courses create noise. Future education needs trustworthy, modular, employer-connected, and worker-controlled skill validation. 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.

rapid spread of plant diseases 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 rapid melting of polar ice sheets and glaciers. 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.

Rapid language change driven by neural interfaces may make ordinary conversation between grandparents and grandchildren impossible without permanent translation layers. The problem is preserving mutual understanding and cultural continuity without forcing everyone onto the same implant standard or erasing linguistic diversity.

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.

AI-designed biological molecules may be created faster than their safety, ecological, and clinical properties can be characterized. The open problem is building evaluation pipelines proportionate to capability and deployment risk. The approach must scale before formal institutions, infrastructure, and land-use systems fully catch up with population growth. 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.

Future outbreaks may involve pathogens for which no profitable commercial market exists. A useful solution requires distributed manufacturing, adaptable platforms, pre-negotiated procurement, and equitable access before an outbreak occurs. 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.

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.

Achieving mechanisms for rapid, transparent and equitable allocation of climate loss and damage finance at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

Current approaches to solutions for providing safe and accessible public transport in rapidly growing secondary cities either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

Automated trading algorithms can sometimes trigger rapid, extreme price swings in smaller or less liquid markets, especially during unusual conditions, without any single actor intending market harm. Building safeguards against this kind of systemic risk remains incomplete.

Over the next two decades, rising resistance in bacteria, fungi, and parasites risks undermining surgery, chemotherapy, and intensive care. Global surveillance networks, rapid diagnostics, and new antimicrobial development platforms are crucial to avert a post-antibiotic era.
