“…Indeed, besides the trends in water supply, several studies project a strong increase in water demand for this region due to population growth and economic development, indicating a higher water stress in the future (e.g., Milano et al 2012). Some studies provide hydrological scenarios on the scale of individual basins in Algeria (e.g., Benhamiche et al 2014;Elmeddahi et al 2014), Morocco (e.g., Brouziyne et al 2018;Tramblay et al 2013b) and Tunisia (e.g., Bargaoui et al 2013;Dakhlaoui et al 2017). Their results indicate a decrease in surface flows that is more pronounced under the RCP8.5 than under the RCP4.5 scenario.…”

“…Döll (2009) identified North Africa as one of the regions with the highest vulnerability to decreased groundwater resources. In this context, there is a strong need for adaptation strategies to limit the impacts of climate change in this region, through an adaptation of agricultural practices and irrigation strategies (Brouziyne et al 2018;Seif-Ennasr et al 2016) and better regulation of well exploitation (Kuper et al 2017). Several studies agree that these adaptation measures should be implemented at the institutional and local levels to encourage a rational use of water that takes into account both socioeconomic and natural constraints and ensure sustainability (Kuper et al 2017;Lezzaik and Milewski 2018;Seif-Ennasr et al 2016).…”

Climate change vulnerability, water resources and social implications in North Africa

et al. 2020

North Africa is considered a climate change hot spot. Existing studies either focus on the physical aspects of climate change or discuss the social ones. The present article aims to address this divide by assessing and comparing the climate change vulnerability of Algeria, Egypt, Libya, Morocco, and Tunisia and linking it to its social implications. The vulnerability assessment focuses on climate change exposure, water resources, sensitivity, and adaptive capacity. The results suggest that all countries are exposed to strong temperature increases and a high drought risk under climate change. Algeria is most vulnerable to climate change, mainly due to the country's high sensitivity. Across North Africa, the combination of climate change and strong population growth is very likely to further aggravate the already scarce water situation. The so-called Arab Spring has shown that social unrest is partly caused by unmet basic needs of the population for food and water. Thus, climate change may become an indirect driver of social instability in North Africa. To mitigate the impact of climate change, it is important to reduce economic and livelihood dependence on rain-fed agriculture, strengthen sustainable land use practices, and increase the adaptive capacity. Further, increased regional cooperation and sub-national vulnerability assessments are needed.

“…This framework is based on the premise that a sustainable pathway to food security in the context of water scarcity lies in maximizing benefits that cut across multiple dimensions of the food-water-climate nexus [64]. This means enabling sustainable agricultural production while reducing vulnerability to water scarcity and optimizing the climate change adaptation and mitigation benefits [65].…”

“…Atmospheric water balance has been assessed in different regions of the earth to provide clues to climate change implications in agricultural water use in terms of variations in net irrigation needs [3,[11][12][13][14][15][16][17][18][19][20]. However, there is no study so far on detecting/assessing the spatiotemporal changes in CWD and CWA employing long-term precipitation and temperature data and trustworthy methods.…”

Changes in Climatic Water Availability and Crop Water Demand for Iraq Region

et al. 2020

Decreases in climatic water availability (CWA) and increases in crop water demand (CWD) in the background of climate change are a major concern in arid regions because of less water availability and higher irrigation requirements for crop production. Assessment of the spatiotemporal changes in CWA and CWD is important for the adaptation of irrigated agriculture to climate change for such regions. The recent changes in CWA and CWD during growing seasons of major crops have been assessed for Iraq where rapid changes in climate have been noticed in recent decades. Gridded precipitation of the global precipitation climatology center (GPCC) and gridded temperature of the climate research unit (CRU) having a spatial resolution of 0.5°, were used for the estimation of CWA and CWD using simple water balance equations. The Mann–Kendall (MK) test and one of its modified versions which can consider long-term persistence in time series, were used to estimate trends in CWA for the period 1961–2013. In addition, the changes in CWD between early (1961–1990) and late (1984–2013) periods were evaluated using the Wilcoxon rank test. The results revealed a deficit in water in all the seasons in most of the country while a surplus in the northern highlands in all the seasons except summer was observed. A significant reduction in the annual amount of CWA at a rate of −1 to −13 mm/year was observed at 0.5 level of significance in most of Iraq except in the north. Decreasing trends in CWA in spring (−0.4 to −1.8 mm/year), summer (−5.0 to −11 mm/year) and autumn (0.3 to −0.6 mm/year), and almost no change in winter was observed. The CWA during the growing season of summer crop (millet and sorghum) was found to decrease significantly in most of Iraq except in the north. The comparison of CWD revealed an increase in agricultural water needs in the late period (1984–2013) compared to the early period (1961–1990) by 1.0–8.0, 1.0–14, 15–30, 14–27 and 0.0–10 mm for wheat, barley, millet, sorghum and potato, respectively. The highest increase in CWD was found in April, October, June, June and April for wheat, barley, millet, sorghum and potato, respectively.
