Assessing the capacity of infill development in the main domains and constructed textures in Ahvaz (zone 2)

Spatial problems, expansion of marginalization, and the formation of worn out tissues, and the lack of balance in the different services of urban districts, and neighborhood of incompatible land use, is the result of the uncontrolled expansion of cities. This will increase transportation costs, infrastructure costs and per capita cost of services in the city. Pay attention to the principles of infill development in areas with capacity in the city, such as: worn, eroded, marginal, exhausted and inefficient urban fabric in addition to the priority areas, can be considered as one of the main strategies to achieve smart urban growth, to prevent and treat these problems. Ahwaz as a capital of the province, the existence of different industries to provide jobs, and diversity in delivering a variety of services, since the imposed war, it is a place of attraction of the migrant populations of the surrounding towns and villages. This led to the formation of spatial problems, as well as the uneven spread of the city and the emergence of a phenomenon known as sprawl in urban areas. The zone 2 of Ahwaz has the largest capacity of Infill Development. The purpose of this document is to identify the capacity of infill development in this zone and to prioritize them. In this research, firstly, the infill development in the three main domains (worn out tissues, wasteland, and incompatible land use) was studied in zone 2 of Ahwaz. Next, to evaluate the infill development capabilities in constructed textures, Indicators of accessibility, physical and social, and to measure the infill development capacity in constructed textures, the DEMATEL technique and fuzzy method was used in the ArcGIS software. The results show that there are about 1720 hectares of wasteland, 114 hectares of military land and 1.5 hectares of ruined land in this zone. Regarding the fabrics built, according to a hierarchical map divided into 5 categories, the first priority is 58 hectares, the second is 354 hectares, the third is 174 hectares, the fourth is 115 hectares and the fifth is 40 hectares, are class's from 1 to 5. The districts of Kian Abad, Seyed Khalaf, Amaniye, East Kianpars and west Kianpars are ranked in the first and second priorities.
