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.

arms flowing to conflict zones 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.

Addressing crop zones moving is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

Surfaces that subtly incline walkers toward certain shops convert public right-of-way into directed marketing infrastructure. The problem is keeping pedestrian geometry neutral and safe rather than commercially steered.

Local referenda that temporarily outlaw certain emotions create zones of enforced affective conformity. The problem is preserving the right to private and public emotional expression while still allowing communities to address genuine collective harms.

Weak enforcement in contested and remote maritime zones allows unsustainable and unlicensed fishing to continue. Satellite-based vessel tracking and community-managed marine reserves could help restore stocks.

Many older buildings in seismic zones like Nepal, Indonesia, and Turkey do not meet modern earthquake-resistant standards. Retrofit financing programs and stricter enforced building codes could save many lives.
