This document discusses the requirements for rebuilding efforts after disasters. It outlines three levels of requirements - basic, intermediate, and expert - related to land, infrastructure, permits, construction materials, logistics, and community buy-in. Coordinating rebuilding in an emergency context is challenging due to the many stakeholders involved. The speaker advocates agreeing in advance on goals, roles, and a plan to bring together all the "pieces of the puzzle." SOCODEVI's role is to organize communities to obtain land, financing, plans, and guarantees to support sustainable housing solutions.
