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.

The problem of locust swarms devastating crops continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

Weak monitoring networks mean swarms are often detected only after major damage occurs. AI-based satellite tracking combined with SMS alerts to farmers could enable faster response.

Millimeter-sized meteoroids travel at tens of kilometers per second and pose catastrophic puncture risks to satellites and spacecraft hulls. Ultra-sensitive impact sensors and wide-field detection arrays are needed.

Lava tubes offer natural radiation shielding for habitats, but traditional wheeled rovers cannot enter steep vertical entrances. Tethered, legged, or flying drone swarms designed for dark micro-gravity caves are needed.

Thickening Mars' atmosphere or cooling Venus requires releasing greenhouse gases or solar shades on a planetary scale. Advanced bio-engineered extremophiles or orbital mirror swarms must be modeled and tested.

Improve forecasting by combining meteorology, vegetation, field observations, and community reporting so control efforts can occur before swarms devastate crops.
