Towards formulating a methodology for the integrated management of vacant areas to enable the development of Egyptian cities

Vacant areas are a vital resource for the provision of housing projects, services, and infrastructure in Egyptian cities, and can be used, according to their sizes, ownership, and shapes, to support sustainable development processes, and according to the databases of the cities under study from researchers, which represent 20 Egyptian cities, vacant areas represent a proportion ranging between 9-35% of the land use budget. In addition, during the period (2015-2020), the state allowed citizens to return the occupied lands, which contributed to the existence of large areas, but there are many challenges facing the vacant areas management system in terms of the lack of an integrated information system in terms of registration, updating maps, information available to investors and inventory of vacant areas in the state. Also, the institutional framework of vacant areas suffers from fragmentation and is a complex framework. The legislative framework also suffers from the conflict of legislation, so there is a need to review and evaluate the situation currently, and what are the successfully integrated management ideas in reforming the vacant areas system to maximize its role in sustainable development in Egyptian cities.
