The geographical spread of these Pacific Islands creates immense problems. Many remote islands cannot handle larger planes landing and may even have fewer people on the ground to undertake adequate initial repairs. Transport may need to be by boat (slow) or smaller aircraft (unable to move larger equipment).
Roads and landing strips need to be cleared rapidly.
Communications may initially be only with radio and sat phones. Buildings and towers may have been totally destroyed. Teams of repair experts may need to be broken apart to reach outlying islands. This may impair restoration.
DRR management requires caches of suitable materiel for recreate the necessary infrastructure. These caches could possibly only be on the largest islands/towns. This still creates difficulties in getting it to where it’s needed if a more remote site is damaged.
