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 digital systems that exclude people without phones or internet. 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.

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.

Treating quiet as a scarce, metered resource excludes those who cannot afford or schedule loans. The challenge is preserving library silence as a public good rather than a rationed commodity.

Roadways that shrink in real time based on predicted density can trap pedestrians and restrict access. The problem is managing crowd flow without creating physical bottlenecks that endanger people or exclude those with mobility needs.

environments that exclude people with disabilities 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.

Seating that morphs to deter anyone except previous users reduces spontaneous social contact and excludes newcomers. The problem is designing street furniture that remains welcoming while still managing wear and anti-social behaviour.

Audio that silences during stillness can exclude people with limited mobility or those who need to remain seated. The challenge is providing movement-linked experiences without turning stillness into auditory deprivation.

Metering park entry according to measured oxygen use could exclude people with higher metabolic needs or certain health conditions. The challenge is creating inclusive green-space access rules that still manage environmental impact without turning basic recreation into a health-based barrier.

Digital commerce, cloud services, and AI platforms can generate value across borders while escaping clear tax authority. The challenge is creating fair tax rules that smaller states can enforce without being excluded from the digital economy. The challenge is especially acute for low-resource administrations, where legacy systems, coordination failures, and weak oversight can magnify harm.

Digital commerce, cloud services, and AI platforms can generate value across borders while escaping clear tax authority. The challenge is creating fair tax rules that smaller states can enforce without being excluded from the digital economy. The challenge is especially acute across fragmented municipalities, where legacy systems, coordination failures, and weak oversight can magnify harm.

Unpaid domestic and care work performed predominantly by women in Papua New Guinea is largely excluded from national economic statistics and social protection policy, undervaluing its contribution.

People with disabilities face extra costs and barriers but are often excluded from mainstream social protection schemes. Inclusive targeting criteria and assistive-technology subsidies are needed.

A persistent gap exists in realizing practical, scalable solutions for supply chain transparency systems that verifiably exclude forced and child labor. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.
