Studying and evaluating the reform and rebuild policies of urban eroded contexts of case sample (Yazd city)

Familiar phenomenon of urbanism development in terms of rapid population growth and uncontrollable cities development emerged almost at many other countries in different historical sectors, has made a more clear impression in two decade after revolution. The population of central contexts of some cities has been removed, the erosion trend of exhausted contexts has been intensified and these contexts have been converted into social abnormalities. Since complete and constant planning and policy making to rebuild and renovate the old urban contexts result in urban sustainable growth while preserving historical-cultural heritage and focusing on their adaptation to environment and cultural constructions, this research try to study and evaluate the reform and rebuild policies of Yazd eroded contexts. Old Yazd neighborhoods such as other ancient contexts require a controlled movement to make sustainable. This movement in form of renovation and rebuilding pattern is discussed with considering the problems like negative growth of population in these localities, lacking necessary inter-locality accesses, ever-increasing development of abandoned and ruined spaces, lacking necessary facilities for green spaces and sport and treatment facilities. These instances are as a cause for other problems as well as an effect for them and have changed context appearance into an abnormal pattern and finally produce this assumption that we must wait for an unpleasant fate about its all values, a fate that will be tied with people’s culture and traditions of this city. The study is in descriptive-analytic, historical method. The results show that new urban construction in Yazd is the consequence of establishing new streets system built without regard to old city construction and its interactive organization with its neighborhood context and with having a wall-like body, have cut the residential contexts into pieces. These streets implement other urban system with different construction, different life and economy, context and life, and possess these features at present too, which could n’t relate to old urban system and cann’t.
