Bangladesh EW4All — Cyclonic Resilience Roadmap
A 2,500-word last-mile implementation roadmap for the 2027 EW4All deadline, optimized for mass-evacuation logic.
NGL Fellowship · Assignment #2 follow-on
§ Abstract
Bangladesh's cyclone preparedness has a globally enviable C_coverage but a slipping A_action where new arrivals to informal settlements lack the multi-generational drill culture of the established coastal communities.
The roadmap reallocates 15% of emergency-response budget into pre-disaster communication infrastructure focused on Bengali-language, mosque- and madrasa-routed alerts.
The DELTA Resilience pipeline is wired to the radio-and-volunteer cyclone preparedness program so a village elder's broadcast carries the same content as a national bulletin.
§ Key findings
- ·A 1-point gain in A_action is ~7× cheaper than a 1-point gain in P_accuracy.
- ·Trust in the alert source is the single biggest determinant of evacuation compliance.
- ·Inclusion protocols for persons with disabilities and the elderly must be drilled, not documented.
§ Methods
- →Warning Efficiency formula applied to coastal district baseline
- →Cost-per-A_action-point benchmarking
- →Inclusion protocol for fast-onset disasters
