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.

Many major rivers depend on glacial melt for a steady water supply, and as these glaciers shrink, the long-term water security of downstream populations becomes increasingly uncertain. Protecting or planning around this shrinking resource remains unresolved.

Developers still occasionally and accidentally commit sensitive credentials directly into shared code repositories, creating avoidable security exposure. More robust default protections against this common mistake remain inconsistently adopted.

Many major rivers and aquifers are being pumped or diverted faster than rainfall can replenish them, threatening long-term water security. Without better management, some regions may simply run out of accessible fresh water.

Current approaches to systems ensuring the reliability and security of digital infrastructure under climate extremes 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.
