This complexity and ambiguity leads to delays in project development, as actors cannot decide which one takes precedence, or how to harmonise both classifications (Wilson, 2016). It also creates serious administrative burden for cities’ officials who operationalise land use changes, BOLUCs and LURCs. Following the formal procedures, development projects have to wait for and comply with a series of land use plans at different scales and from different institutions (see Box 2.16).
