Journal of Geography and Regional Development Vol 16, No. 2 (2018-2019) – Serial Number 31 7 Dealing with Environmental Degradation Caused by Urban Sprawl Uusing Smart Code as a New Approach (Case Study: Qazvin City and its Peri Urban Area) Farrokh Moshiri Assistant Professor in Urban Planning, Shahid Beheshti University,Tehran, Iran Asieh Nikbin 1 PhD Candidate in Urban Planning, Shahid Beheshti University,Tehran, Iran Received: 26 September 2016 Accepted: 24 October 2017 Extended Abstract 1. Introduction Over a period of 26 years, the population of Qazvin has increased by 1.6 times, while its size has become 2.9 times greater. This imbalance between population and urban area growth is called urban sprawl. Sprawl pattern causes many problems, especially in the environmental field. For example, thousand-years-old gardens in the south area of Qazvin is destroying due to urban sprawl pattern. Green belt gardens around Qazvin city purifies south industries pollution and improves air pollutant indexes Thus, finding a solution to dealing with these consequences seems to be necessary. In this study, in order to in front Qazvin sprawl pattern and environmental issues arising from it, based on the smart code instructions, a model is suggested. According to this model, the proposed strategies are listed. 2. Review of Literature Most critics agree that the major problem of general urban growth is urban sprawl. There is a broad agreement on how to tackle the current patterns and smart growth option, as anti-sprawl has been accepted. In spite of this convergence and high advertising, urban growth shift in the United States has slow speed due to traditional zoning. Smart code is proposed as an alternative for traditional zoning and solving problems related to urban sprawl. Smart code is a model which combines the special development code with urban design and land use planning. This special development code has been proposed by Duany, Plater-Zyberk and Co (2003) headed by Anders Duany. The smart code principle supports communities with urban centers, transport, Pedestrian-oriented and mixed residential complex which encourages natural and environmental protection. 3. Method According to the proposed model, regional sector codes based on smart code instructions will be prepared after determining the study area. Since these codes 1. Corresponding author.
