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 fleets of autonomous vessels may survey, extract, monitor, or patrol oceans without continuous human control. The challenge is establishing safety, attribution, environmental limits, and collision rules across maritime jurisdictions. 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.

Fabrics that log the heat signature of every touch create persistent records of physical interaction. The problem is preventing wearable materials from becoming continuous contact surveillance devices.

AI, automation, caregiving, health events, and climate disruptions may make stable employment less common. The challenge is designing benefits, credentials, insurance, and taxation systems that follow people across changing forms of work. 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.

Infrastructure maintenance that fills gaps with glowing commercial messages turns every walk into an ad exposure. The challenge is funding public repairs without converting the pavement itself into continuous commercial real estate.

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.

Official documents that continuously revise expected lifespan can shape education, insurance, relationships, and self-perception from birth. The challenge is providing useful health information without embedding deterministic forecasts into legal identity.

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.

Statues that continuously change expression or posture according to live public sentiment risk turning monuments into unstable opinion mirrors. The problem is allowing cultural responsiveness without erasing the original historical record or creating permanent contention over every figure.

When collective memory of shared events is rewritten in real time by majority vote or algorithmic consensus, no stable historical baseline remains. The problem is creating durable, independently verifiable archives that coexist with participatory updating without being overwritten.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

Urban growth, migration, and climate change will outpace traditional master planning. The challenge is designing governance that can revise land use, service delivery, and infrastructure priorities continuously without becoming arbitrary. This becomes particularly difficult in post-conflict institutions, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

Current approaches to technologies enabling the continuous monitoring of air quality and its health impacts at high resolution 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.

Many aging pieces of infrastructure lack continuous, affordable monitoring systems capable of detecting subtle structural problems well before they become dangerous. Making this kind of predictive monitoring widely affordable remains an unresolved engineering challenge.
