A correlation is demonstrated between pollution and areas with high population density coupled with low green spaces. They present a short, mid and long term strategy to improve the environment. It is suggested that the high cost of land in worst affected areas necessitates creative solutions such as roof gardens. A mid to long term strategy of conserving existing green spaces and developing new areas is suggested. It is also suggested that biodiversity be introduced by planting appropriate species to address specific ecological conditions and create planned connections between fragmented green areas to create larger overall interconnected units.
In this paper, Ketabi gives suggestions to implement sustainable urban development in the Tajrish area of Tehran with economic, social and environmental dimensions. Ketabi places these suggestions in perspective by identifying the current environmental and urban state of the city which is regarded among of the most polluted in the world. Through data, fast population growth and continued extensive use of old vehicles are identified as prime causes of pollution. Tajrish district, which is one of the fastest growing suburbs of the city, suffers from unplanned growth. The bus terminal is a major source of pollution as is the large number of cars going to central Tehran. Ketabi suggests that the mass transit subway connection to Tajrish be completed early to reduce the traffic and pollution burden and also explains other suggestions for traffic management. In addition, the old prized cultural heritage of this area is being destroyed by fast and unregulated construction. It is suggested that campaign must be run to educate the area’s inhabitants about its heritage, parts of the old city be revived, and architectural heritage be preserved aesthetically.
