I have no specific examples to draw from unfortunately as my understanding of developing countries’ coordination and communication systems in disasters is lacking – although that in itself could be telling. The Nepalese earthquakes stretched existing communication structures between various services (although I cannot comment on how formalised or rigorous these were prior to the earthquakes) – certainly between medical services and other organisations and services – and resulted in an opaque centralisation of command in the national government. Would be quite interested to hear what everyone else thinks!
