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.

Sudden spikes in the price of staple commodities like wheat or rice can trigger food crises in import-dependent countries almost overnight. A more resilient global system to buffer these shocks remains unbuilt.

Malnutrition during early childhood can cause lifelong developmental harm, and crises like war or drought regularly disrupt food access for vulnerable children. Building more resilient food delivery systems in crisis zones remains urgently unresolved.

Wars, droughts, and shipping disruptions can send food prices soaring almost overnight, hitting poorer households hardest. A more resilient global food system could soften these shocks before they cause real hunger.

Build affordable monitoring and response systems that identify local environmental threats before they become chronic public-health crises. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.

A persistent gap exists in realizing practical, scalable solutions for institutional designs that reduce the risk of nuclear escalation in multipolar crises. 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.
