“…Norouzi said that it should be noted that all the consequences of water shortages are related to each other, and they can not be separated. According to the available statistics from 1901 to 1997, the situation of Iran's rainfall changes in the northern regions is predicted to decrease rainfall [6][7][8][9]. The change of precipitation regime in the central region of the southern slopes of the country from the Persian Gulf of Alborz to the area between the eastern slopes of the Zagros to the central regime is expected to increase rainfall.…”

“…Many studies have projected increased water demand due to CC, increasing water scarcity in many regions over the next several decades, and enhancing the intensities of extreme events (like droughts and floods) in the water cycle. Weather extremes are expected to increase every year [46][47][48][49][50]. Even without a clear linear relationship between T and P in the climate models, increasing T is believed to promote P [51][52][53][54].…”

Climate Change, Land Use/Land Cover Change, and Population Growth as Drivers of Groundwater Depletion in the Central Valleys, Oaxaca, Mexico

Groundwater depletion is an important problem driven by population growth, land use and land cover (LULC) change, climate change, and other factors. Groundwater depletion generates water stress and encourages unstainable resource use. The aim of this study is to determine how population growth, LULC change, and climate change relate to groundwater depletion in the Alto Atoyac sub-basin, Oaxaca, Mexico. Twenty-five years of dry season water table data from 1984 to 2009 are analyzed to examine annual groundwater depletion. Kriging is used to interpolate the region’s groundwater levels in a geographic information system (GIS) from mapped point measurements. An analysis of remotely sensed data revealed patterns of LULC change during a 34-year (1986–2018) period, using a supervised, machine-learning classification algorithm to calculate the changes in LULC. This analysis is shown to have an 85% accuracy. A global circulation model (GFDL-CM3) and the RCP4.5 and RCP8.5 scenarios were used to estimate the effects of climate change on the region’s groundwater. Estimates of evapotranspiration (using HELP3.5 code) and runoff (USDA-SCS-CN), were calculated. Since 1984, the region’s mean annual temperature has increased 1.79 °C and urban areas have increased at a rate of 2.3 km2/year. Population growth has increased water consumption by 97.93 × 106 m3/year. The volume of groundwater is shrinking at a rate of 284.34 × 106 m3/year, reflecting the extreme pressure on groundwater supply in the region. This research reveals the nature of the direct impacts that climate change, changing LULCs, and population growth have in the process of groundwater depletion.

“…Drought has caused many rural people in Iran to lose their jobs and income, especially people whose lives depended on water and agriculture, and forced them to migrate. Accordingly, drought is a common phenomenon and a part of normal life in Iran; however, it is also predicted that the country would be hotter and drier due to climate change with more pressure on water resources 102 and agriculture 103 . Agricultural activities in Iran are susceptible to droughts: one mm of rainfall below the historical average leads to approximately US$ 90 million losses in the agriculture sector 79 .…”

Dealing with environmental migration is a complex problem that may transform into a wicked problem. To investigate the environment-migration nexus, it is necessary to develop a conceptual model that considers the complexity of environmental changes as a cause of rural-urban migration (RUM). This paper provides such a model, focusing on the decline of agricultural lands and products and relevant economic consequences. It links the three leading “push factors” of RUM—climate change, human mal-activities, and hydro-climatic disasters— and migration. Also, it incorporates the pull factors in cities and intervening factors, such as governmental plans and individuals’ characteristics. The model contributes to bridging the knowledge gap on the effects of migration policymaking on the one hand and environmental and climate change on the other hand. It increases understanding of the full range of human responses to environmental and climate change and can be used for policymaking through sustainable management plans.
