Reviewing and assessing principals and criteria of resilience in urban gardens sustainability (Case Study: District 1 of Tehran Municipality)

Escalating population growth, passion for settling in cities, and unrestrained expansion of urban areas have affected most of open spaces and constructions. Uneven expansion of Tehran city threatens the gardens as well, especially in district 1 of Tehran Municipality. Therefore, it is of immense importance to identify and conserve remaining gardens. As part of urban green spaces, gardens have significant influence on efficient function of cities as human habitats. This research's goal is investigating effective factors in resilience of urban gardens, and also determining the significance of each factor in district1 of Tehran city. The research is conducted through descriptive-analytical method and classified as practical studies. For determining gardens' natural- structural resilience indicators, 20 faculty members and experts in the fields of environmental planning, urban and rural planning, urbanization, green spaces, and gardening were selected. Weighing the criteria was conducted by FANP method. Preparing digital layers was implemented in Geographical Information System (GIS) and ENVI. Prepared layers were then fuzzified in IDRISI and overlaid in ARC MAP. According to the resultant map of resilience in urban gardens of district 1, gardens in region 3 are totally resilient. In the contrary, gardens in region 7 have moderate resilience and are in some parts vulnerable. In region 9, gardens are in a range of totally resilient to vulnerable.
