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.

Addressing sandstorms burying towns 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.

Thousands of satellites may provide connectivity while increasing collision risk, radio interference, light pollution, and disposal complexity. The challenge is creating enforceable coordination and end-of-life standards across commercial and state operators. 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.

Modern software often relies on long chains of interconnected code packages, and a single broken or malicious update deep in that chain can cascade into failures across countless unrelated projects. Making this system more resilient remains an unresolved structural issue.
