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.

Future progress on human development and planetary health depends on solving localization of aid remaining slow. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

The problem of clearance remaining slow 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.

rural electrification remaining slow remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Traditional credentials are too slow for rapidly changing technical work, while unverified short courses create noise. Future education needs trustworthy, modular, employer-connected, and worker-controlled skill validation. 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.

Climate change and urban pumping changes may cause groundwater to enter basements, transit systems, utilities, and foundations. Cities need mapping, waterproofing, drainage, and financing strategies that address slow cumulative damage. The design must remain functional when standards, trade routes, data access, and diplomatic cooperation are unreliable. 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.

The problem of help arriving too slowly after disasters continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals.

Addressing bureaucracy that is painfully slow 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.

Clocks that accelerate or slow according to local output targets fracture shared temporal reference. The challenge is maintaining a common civic time base while still allowing local performance incentives.

Drought, salinization, erosion, and heat may displace people gradually rather than through one visible disaster. The open problem is creating legal pathways, funding mechanisms, and host-community planning before displacement becomes coercive. 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.

Some websites secretly run scripts that use a visitor's device to mine cryptocurrency without their knowledge, slowing down devices and consuming electricity without consent. Consistent detection and blocking of this practice remains incomplete across browsers.

Wireless carriers often prioritize dense urban areas for network upgrades because they're more profitable to build out, leaving rural regions with slower, less reliable coverage. Closing this rural connectivity gap remains a persistent infrastructure challenge.
