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.

If legal names must be renewed annually like licenses, administrative barriers and fees can strip people of identity continuity. The problem is designing naming regimes that allow flexibility without turning a core personal identifier into a recurring bureaucratic burden.

Localised gravity fluctuations caused by energy or structural load management can injure residents and damage property. The challenge is designing buildings and occupancy rules that prevent such failures or make them predictable and survivable without requiring constant monitoring.

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.

Smart textiles that adapt to and then lock in a wearer’s patterns can limit self-expression and create unwanted permanence. The challenge is designing garments that learn usefully without removing the wearer’s ability to change appearance or discard unwanted adaptations.

Shadows may become information-rich surfaces that can be scanned or recorded without the person’s knowledge. The problem is establishing ownership and consent rules for the data carried by one’s own silhouette while still allowing beneficial environmental sensing.

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.

Interactive reconstructions of dead relatives may demand ongoing inclusion in gatherings, decisions, and emotional life. The problem is setting boundaries that respect both the living family’s autonomy and any residual rights or wishes of the deceased without forcing perpetual digital presence.

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.

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.

States and institutions may need registries of deployed AI models, their data sources, risk levels, and accountability owners. The challenge is building disclosure rules that support safety without exposing legitimate security or privacy risks. This becomes particularly difficult during fiscal austerity, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

States and institutions may need registries of deployed AI models, their data sources, risk levels, and accountability owners. The challenge is building disclosure rules that support safety without exposing legitimate security or privacy risks. This becomes particularly difficult under climate migration pressure, because public institutions must remain fair, resilient, and accountable while adapting to new risks.

When personal memory archives exist solely in distributed cloud systems, sudden or gradual data loss can erase formative experiences without local backups. The challenge is building durable, verifiable, and accessible long-term personal memory infrastructure that survives corporate failure, format obsolescence, and account lapses. Solutions should remain affordable, user-controlled, and recoverable even decades later.

Future technologies may allow external parties to alter or insert content into shared dream environments while people sleep. The problem is establishing consent, ownership, and integrity boundaries for experiences that occur outside waking awareness. Any solution must define measurable harms, protect privacy without eliminating beneficial dream-sharing uses, and function across different neural interface standards.

As digital navigation layers become permanent fixtures in daily life, physical landmarks lose meaning and people lose the ability to orient themselves without screens. The challenge is creating systems or practices that preserve spatial awareness and independent wayfinding while still allowing beneficial digital tools. Solutions must work across cultures, age groups, and infrastructure levels, avoid creating new dependencies, and remain usable when networks fail.

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.

Severe solar storms can disrupt satellites, power grids, navigation, aviation, and communication networks. Future resilience requires better forecasting, hardened systems, coordinated shutdown procedures, and affordable protection for developing countries. Affected communities must have meaningful control over data, revenue, deployment decisions, and the right to refuse harmful applications. 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.

Biometric identity can reduce fraud while also excluding people whose fingerprints, faces, or documents do not match. The open problem is creating identity governance that is secure without making access to basic entitlements brittle. The challenge is especially acute in informal settlements, where legacy systems, coordination failures, and weak oversight can magnify harm.
