Kito’ response design comes from an accurate assessment of the operating environment. We have analysed the typical temporary first-emergency structures used following a natural disaster where we operate. These structures are often inappropriate to withstand major natural disasters. This is the case in most contexts with unstable tents and huts built where the urban legislation is limited, where land ownership is not well defined and where it is often difficult to get the authorizations needed for building semi-permanent and/or permanent facilities.
