While PRIM
could borrow from the IRLR model, the current framework for restitution considered best practice by IFIs, would be
onerous for governments with thinly spread resources and a lack of institutional or technical capacity to implement
resettlement in densely packed urban areas. Balancing the uncertainty, potential for impoverishment, and cost of
resettlement against the gains in lives to be saved and recovery costs avoided, preventive resettlement is justifiable
as a suitable option for recently inhabited informal settlements in extremely hazardous locations.
