Correlation Analysis of Spatial Population Movements and Environmental Challenges in Iran
Abstract
Establishing a balance between natural resources and the environment and population growth, followed by increasing human needs, is an issue that should be the focus of policy makers and population planners to ensure sustainable development in the country. Human population is both affected by climate changes, so it is important to identify the relationship between population and the environment primarily because of the extent of the effects of population on the environment. Therefore, the present study intends to use the discovery of the relationship between population movements and environmental indicators while explaining the prevailing conditions in the country, to provide solutions to implement these strategies, to achieve greater stability in Iran. The research method of this research is descriptive-analytical based on secondary data. In line with the purpose of the research, 5 components (climate, water, soil, air, natural hazards) and 9 indicators have been used. In the data entry and sorting stage, Microsoft Excel software and in the data analysis stage, SPSS software and Pearson correlation coefficient were used to consider the correlation between environmental data and demographic movements. GIS is used and the data output is displayed in the form of maps, tables and graphs. The results of the present study that population movements in Iran have no environmental origin, but these movements and migration of some provinces during the study period (1986-2016) have caused several environmental crises. Among the effects of population displacement on the environment can be mentioned the uncontrolled abstraction of groundwater and the water crisis, as well as the occurrence of subsidence in the continuation of this issue. Also, human activities due to population increase and destruction of vegetation in and around cities have intensified natural hazards.
