“…However, the projections show a reduction of around 5% under RCP 2.6. The results of this study are consistent with those of [48,49], indicating an average decline in the water resources of the Tigris River in the range of 8-50% compared with observations recorded in the last three Referring to S3, Table 6 shows the percentage of irrigated areas that should be dimensioned to maintain the minimum requirement of flow in the streams for river environmental purposes and to eliminate water stress in Diyala and Basrah. In Diyala (Basrah), the irrigated area should be diminished by lower and upper limits of 8 and 68% (47% under RCP 8.5 and P3) under RCP 2.6, P1 and RCP 8.5, P3, respectively, compared with the irrigated area in the RP.…”

Climate change and population growth play crucial roles in the planning of future water resources management strategies. In this paper, a balancing between projected water resources and water demands in the Iraqi Part of the Tigris River Basin (TRB) was evaluated till the year 2080 based on RCPs 2.6, 4.5 and 8.5 and population growth. This paper examined a sustainable adaptation plan of water resources in the TRB considering three scenarios; (S1) as no change in the current strategy, (S2) as improved irrigation efficiency and (S3) as improved irrigation and municipal water use efficiency. The results showed a decline in streamflow will occur in the range from 5 to 18.4% under RCP 2.6 and RCP 8.5, respectively. The minimum increase in water demand is expected for RCP 2.6 (maximum increase for RCP 8.5) by 51.8 (208.2), 9.9 (42) and 1.2 (7)% for the municipal–industrial, irrigation and environmental water demands, respectively, compared with the RP. The main finding indicated that S1 is the worst scenario, with water stress in four provinces, especially on the warmest RCP. Whereas, under S2 and S3 conditions, water stress can be eliminated. Increasing ambition towards adaptation becomes obligatory for developing sustainable water sources, supporting water food securities and increasing resilience towards climate change.

“…Literature shows that considerable research work was conducted on marsh restoration (Curtis et al, 2005 ; DAI, 2006 ; Iraqi Ministries of Environment et al 2006 ; CRIM 2007 unpublished report; CRIM 2008 unpublished report; Riyadh et al, 2008 ; CRIM 2009a unpublished report; CRIM 2009b unpublished report; Al-Saboonchi et al, 2011 ; Al-Ameri and Jassim ( 2011 ); Al-Ansari & Knutsson, 2011 ; Al-Ansari et al, 2012 ; Muhannad et al, 2013 ; Al-Gburi et al, 2017 ; Al-Khafaji et al, 2018 ; Al-Khafaji et al, 2021 ; Bayda et al, 2022 ). Furthermore, various studies have shown that Iraq is one of the most vulnerable countries to climate change and its water resources begin significantly impacted, such as Chenoweth et al ( 2011 ), Abbas et al ( 2016 ), Abbas et al ( 2017 ), Awchi and Kalyana ( 2017 ), Al-Khafaji and Al-Chalabi ( 2019 ), Constantinidou et al ( 2019 ), and Saeed et al ( 2021 ).…”

The application of restoration plans for the Iraqi marshlands is encountering significant challenges due to water scarcity and the impacts of climate change. This paper assesses the impact of water scarcity on the possibility of continuing the application of restoration and sustainable management plans for the main marshlands in Iraq. This assessment was conducted based on the available data and expected situation of available water resources under climate change conditions until the year 2035. Additionally, a satellite image–based index model was prepared and applied for the period 2009–2020 to obtain the spatiotemporal distribution of the restored marshlands. The results show that the shortage in water resources and insufficient inundation rates prevented the adequate application of the restoration plans. Also, applying the scenarios of distributing the deficit equally over all water demand sectors (S1) and according to the percentage of demand for each sector (S2) shows that the expected deficit in available water for the three marshes by the years 2025 and 2035 will be approximately 25% and 32% for S1 and 9% for S2. Consequently, the considered marshes are expected to lose approximately 20 to 33% of their eligible restoration areas. Accordingly, looking for suitable alternatives to support the water resources of these marshes became a very urgent matter and/or recourse to reduce the areas targeted by inundation and being satisfied with the areas that can be sustainable and maintain the current status of the rest of the regions as an emerging ecosystem characterized by lands that are inundated every few years. Accordingly, steps must be urged to develop plans and programs to maintain the sustainability of these emerging ecosystems within the frameworks of climate change and the conditions of scarcity of water resources and water and air pollution to ensure that they are not lost in the future.
