Effective factors on improvement of the environmental quality in Informal Settlement areas with a resident satisfaction approach (Case Study: Bisim neighborhood of Zanjan)

In recent decades, along with the uncontrolled development of urbanization and the decline in the quality of residential environments, finding a solution to find an effective solution to improve environmental quality has become one of the most important concerns of managers and urban planners.

To improve the environmental quality in neighborhoods with unconventional housing and identify the factors affecting the satisfaction of residents.

The present study is descriptive-analytical in terms of applied nature and method. The statistical sample size was determined to be 376 people using Cochran's formula and simple random sampling method. The data obtained from the questionnaires were evaluated using exploratory factor analysis and linear multivariate regression. After extracting the criteria, a one-sample t-test was used to measure the environmental quality of the neighborhood and the level of citizens' satisfaction.

Studied Areas: 

Dense Bisim neighborhood in the northeast of Zanjan with an area of ​​approximately 82 hectares of rural areas without a core is the target neighborhood of the study.

Regression test on "physical", "social", "functional", "perceptual" and "managerial" factors shows that there is a linear relationship between the main components (independent variables) and neighborhood quality (dependent variable). Is established. Also, due to the high factor load of the "physical" component, the variables of this factor are more correlated with the environmental quality of the Bisim neighborhood and the existence of a significant relationship between environmental quality factors and residents' satisfaction is confirmed. Finally, after the component of space and permeability organization, which is in the first rank of residents' preferences for improving the quality of the neighborhood; the variables of "managerial" factor such as: "control and supervision", "management and maintenance", "providing visual and environmental comfort" are in the next priorities. Among the "perceptual", "social" and "functional" factors, the components of "safety and security", "social interactions", "compatibility and homogeneity" and "accessibility" have been emphasized by the residents in relation to other components.

The results of the study of effective factors in environmental quality index show that improving the quality of Bisim neighborhood requires simultaneous attention to all factors involved in environmental quality and quality of life depends on equitable distribution of services and urban facilities and increase their life satisfaction.
