Classification and preparation of land use map are the most commonly used methods in remote sensing data. Numerous advanced classification methods have been developed in a recent year. Among those methods, one can name support vector machine. Identifying land cover changes can play an important role in future decisions of regional managers. Therefore, the present study aimed at employing CA–Markov model to present a powerful but simple model for simulation and prediction of Yazd city. Accordingly, first, satellite images of 2000, 2005, 2010, and 2016 were classified by SVM method, and then land use maps of Yazd city were extracted. The results of the detection of changes indicated the expansion of residential areas and the reduction of dry land and vegetation during a 16-year period. Prediction of land use development in 2040 using CA–Markov model with a kappa coefficient of 84.43 shows the high accuracy of this model. Besides, the urban land use area shows 18,432 hectares increase in 2040 compared to 2010, while the area of dry land uses (− 15,570) rocky areas (− 186) and vegetation (− 2658) hectares decrease compared to 2010. Moreover, the results of CA–Markov model indicated the development of Yazd city by degradation of vegetation.

Rapid population growth and its focus on cities have affected the lives of people; and poverty, environmental degradation, pollution, lack of utilities, the decline of existing infrastructure, and lack of access to land and adequate shelter are the crises related to this issue. Cities as a centralization of people's activities and human's life do not have any choice except to accept the structure and function of system of health to ensure their sustainability; so the system of health, safety and the environment will be effective as an integrated system to manage urban. The aim of this study is to survey and determine people's point of view about health, safety and environment issues of cities they live in. Ultimately the results are used for favourable urban management and improving health, safety and environment criteria of the second district in Yazd city.Therefore, after determining the factors affecting health, safety and environment of the city through library studies and previous activities carried out, to get the citizens' opinion the questionnaire was used and the results were analyzed by SPSS. Results show that people's point of view about desirable criterion environmental indices is 64%, about desirable criterion health indices is 66.4% and about desirable criterion safety indices is 67.4%.
