This seems like... a bad idea? If I understand you correctly, each region maintains disaster relief infrastructure & staff with help from the central/national government? If so, does that translate to richer regions being less affected by calamities (since they can pour more money into said infrastructure than the bare minimum)?
In most countries (with such plans in place) the national government maintains all disaster relief management to assist local governments, right?
Sorry I've asked a lot of questions, but I'm genuinely interested to know!
