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.

By the time illegal logging is discovered, the trees are often already gone and the damage is done. Real-time detection and enforcement could protect forests before, not after, they disappear.

As AI moves from answering questions to taking real actions, like managing money or controlling machinery, mistakes carry real consequences. We still lack agreed safety standards for how much autonomy is safe to hand over.

AI can now produce convincing text, images, and video in seconds, and detection tools are struggling to keep up. Without a reliable way to tell real from fake, public trust in what we see online keeps eroding.

Current approaches to real-time monitoring and response systems for industrial chemical and oil spill events 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.

Achieving protocols for equitable and rapid distribution of medical countermeasures in pandemics at meaningful scale demands simultaneous progress in fundamental research, engineering integration and socio-technical systems that work for low- and middle-income settings. Existing efforts remain fragmented relative to the magnitude of the challenge.

The absence of robust, context-adapted solutions for methods for restoring the productivity and resilience of agricultural systems under climate change creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.

Despite recognition of its importance, reliable methods for teacher development platforms producing national-scale practice change are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.

A persistent gap exists in realizing practical, scalable solutions for industrial-scale lunar propellant and structural material production. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.
