Climate Change and Ecological Migration: A Study of Villages in the Province of Khuzestan, Iran

Abstract

Although the most extensive immigration flows among urban and rural settlements have so far been economic migrations, climate change has recently become a decisive factor for migration in many parts of the world with ecological migration becoming the dominant model in these demographic movements. Khuzestan province with a strategic position in southwest of Iran and with a 30% share of rural population is one of the provinces that has been affected by widespread climate change over the past two decades, experiencing massive population movements, especially in the rural areas. Studies have shown that the increasing trend of temperature and the decreasing trend of precipitation are the most important and most obvious outcomes of climate change that has provided a platform for population displacement in rural areas of Khuzestan. This enormous flow in the rural parts of the province has become a multi-level (local, regional, national and even international) challenge. The purpose of this study is to investigate and analyze the effects of climate change on demographic movements in the rural settlements of Khuzestan province. The study is descriptive-analytic and the information is extracted from the database of the Statistics Center of Iran. Statistical analysis has shown that the decline in the rates of rural population growth from −02 in 1986 to −4.6 in 2017 and the evacuation of more than 2,398 villages over 1986−2017 have been directly and indirectly related to the diverse effects of climate change.

Understanding climate-induced migration in West Africa through the social transformation lens

“…The movement can be "voluntary or involuntary, triggered by a rapid-onset disaster or slow-onset climatic process, … informed by political factors and human intentionality" (McAdam, 2014, p. 17). Dehcheshmeh and Ghaedi (2020) observe that the movement can also be seasonal and singular. In recent times, the terminology "climate-induced migration" is increasingly being used in policy documents (Sharifi et al, 2021).…”

Towards the development of a conceptual framework for Complex interaction between environmental changes and rural-urban migration

“…For example, according to the interviews conducted in Khuzestan, some unemployed people out-migrate to nd a job in other cities and, some employed people are looking for better economic situations and indeed for a better future 108 . Studies in Khuzestan province show that 35-40% of rural migrants changed their jobs over the last four census periods due to environmental and economic factors 111 . Seeking better economic situations in combination with cities' attraction and social network in the cities increase the rate of RUM.…”

Do Resettled People Adapt to Their Current Geographical Environment? Evidence from Poverty-Stricken Areas of Northwest Yunnan Province, China

“…PAR aims to create conditions for subsequent poverty alleviation and development by relocating the rural poor. In developed countries, similar concepts to PAR are environmental migration [34,35] and ecological migration [36]. The research mainly involves six aspects: biodiversity conservation, poverty and pro-poor environment, climate change and regional conflicts, resettlement areas, emigration areas and sociological issues of environmental refugees.…”
