Human priorities
Start with the people closest to the problem.
Access and continuity
Damaged roads, bridges, electricity and communications isolate mountain communities and health services. Offline-capable information matters.
Children and separated families
Family tracing and child protection require trained organizations, strict consent and minimal data—not public lists of names or locations.
Bounded open-source work
Build around accountable response—not around vulnerable people.
Access-map verification
Help trusted mapping teams validate damaged routes and bridges from public imagery. Mark uncertainty and never route people into hazard zones.
Low-connectivity information
Package verified notices for SMS, print and intermittent connections, with Nepali-language review and an explicit publication time.
Needs and restoration tracking
Prototype aggregated, non-personal tracking for water systems, clinics and shelters using humanitarian standards such as HXL.
Privacy-preserving reunification
Support recognized protection actors with consent-led workflows. Never publish survivor identities, children’s records or precise locations.
