Investigating the Interaction of Demographic Change and Environmental Resources in Iran (With an Emphasis on the Water Issue)

The population of the earth between 1960 and 2018 has risen from three billion to over seven billion. During this period, humankind has made unprecedented changes in the global environment. The relationship between population and environment is a two-way relationship. On the one hand, population growth and industrial progress impact on the environment, and on the other hand, environmental changes, drought and global warming, and the melting of glaciers ... affect population dynamics. With regard to environmental issues that have become acuter in recent years due to global warming and increasing greenhouse gases, increasing attention to the problem of population growth and the impact that population growth can have on the environment, is a concern an important issue for demographers. Environmental crises, especially the water crisis in recent years, have raised the question of whether Iran is capable of sustaining this population due to carrying capacity of the land. To this end, in this study, using a library method, the relationship between population and environment has been investigated. The results of the surveys showed that with a population increase of 106 million by 1420 and 107 billion cubic meters of drinking water needed for this population, and the continuing shortage of water in the country, as well as the lack of renewable water resources, the country faces challenges in the future.
