Implementing proven strategies against global cooperation remaining weaker than needed by 2030

open<br>Global, Global

Future progress on human development and planetary health depends on solving global cooperation remaining weaker than needed. 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.

Implementing proven strategies against climate impacts hitting the poorest hardest by 2030

open<br>Global, Global

climate impacts hitting the poorest hardest 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.

Building effective interventions for water sanitation and hygiene gaps persisting by 2030

open<br>Global, Global

The problem of water sanitation and hygiene gaps persisting 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.

Establishing robust mechanisms to tackle stigma around menstruation remaining by 2030

open<br>Global, Global

Addressing stigma around menstruation remaining 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...
