“…Actually, the effort of the country focuses more on major works than on the infrastructure of user services, and on the investment than on the actual management of the water. A number of persistent difficulties and shortcomings prevent the management of water resources to fully meet the needs of the population and the socio-economic development (Benblidia and Thivet, 2010; Kherbache, 2020). These are, in particular, as follows: The lack of comprehensive technical, financial and economic analyses to compare various water management strategies. The water sector’s capital expenditure has a low absorption capability. A lack of consistency between the water development plans chosen and the key objectives of productive sectors, particularly agriculture. The inefficient use of water in drinking water delivery and agricultural irrigation. Siltation of reservoirs and dams because of under-utilization of hydraulic equipment capacities. There is multidimensional reliance on foreign corporations, as well as a technological reliance on equipment and engineering. …”

PurposeThe first aim of this study is to show the impact of global warming on temperature and precipitation changes in Algeria. The second objective is to exhibit the strategy planned by the country to mitigate these effects on water resources in the future.Design/methodology/approachThis research assesses the expected changes in temperature, precipitation and SPEI index, over Algeria (16 weather stations), between two horizons (2030, 2050), by using an ensemble of 16 general circulation models under RCP2.6 and RCP8.5 scenarios.FindingsMore warming and drought will be experienced under RCP8.5 than RCP2.6 scenario. The highest warming is observed at the Southern stations. However, the lowest precipitation is projected in the western stations. The results of SPEI calculation indicate that the severity of drought spread progressively across time and space. The highest values were observed over 2050 with values varied between 0.15 and −2.08 under RCP2.6 scenario, and range from −0.73 to −2.63 under RCP8.5. These results indicate that Algeria is highly vulnerable to the impact of climate change on water resources, which stressed the need to develop a strategy against this situation.Originality/valueThis study is one of the first to simulate the future climate changes over 16 Algerian weather stations by using an average of 16 general circulation models data, under two RCP scenarios. This study shows the 2030 water development strategy to mitigate the effect of drought and water scarcity on different sectors.

“…Despite the presence of these natural resources, water scarcity is a significant issue in Algeria. This scarcity is primarily attributed to recurrent droughts and the mismanagement of water resources, exacerbated by factors such as a substantial population growth, improved living conditions, urban and industrial development, and more (Kherbache, 2020). This phenomenon has adverse effects on meeting water requirements and allocating water for various purposes (Hamiche et al, 2015).…”

The aim of this study is to assess the relationships between the main stakeholders involved in water management in Sidi Bel Abbes city (western Algeria) to establish pathways for good governance, fair allocation and sustainability of water resources. A multi-stakeholder analysis was performed using the MACTOR method (method of actors and power relations) to analyze stakeholder strategies, alliances, and potential conflicts regarding water management. Data for the study were collected mainly during multi-stakeholder workshops with 6 main stakeholders who are directly involved in managing potable water. A field survey of 329 local households was conducted with the use of supplementary questionnaires. This study proposes that the power dynamics among actors should be considered during the decision-making process to improve collaborative interactions and the effectiveness of stakeholders engaged in water management. The research findings show that the stakeholder’s roles and strategies should be coordinated and strengthened to ensure equitable allocation of water. Technical public agencies deploy management strategies that do not consider water quality as a priority, and they are more concerned with other strategic objectives. Additionally, the stakeholders disagree on many issues relating to water management due to overlapping and conflicting powers, which threatens the quality and availability of water resources. The study also demonstrated that the National Sanitation Office could play an important role as a relay stakeholder and that the Hydrographic Basins Agency should strengthen alliances and commitments with all stakeholders. Enhancing the participation of these stakeholders in water management procedures and empowering domestic water end users, particularly in densely populated residential areas, could help bridge divides and foster a unified approach to achieving sustainable water management objectives.

“…The southern region depends on groundwater, especially in the southern Saharan region, where mainly fossil water is exploited, which is characterized by little recharge [5]. The water demand has been increasing considerably because of the increasing population and the proliferation of agriculture and industries, which means that some of these aquifers are being over-exploited [2,6]. Furthermore, according to the Algerian Minister of Water Resources, the quantity of drinking water consumed across the country increased in 2020 by 10% since the start of the COVID-19 pandemic, which sparked many protests, especially in Ain Sefra [7].…”

Groundwater Potentiality Assessment of Ain Sefra Region in Upper Wadi Namous Basin, Algeria Using Integrated Geospatial Approaches

Water demand has been increasing considerably around the world, mostly since the start of the COVID-19 pandemic. It has caused many problems for water supply, especially in arid areas. Consequently, there is a need to assimilate lessons learned to ensure water security. In arid climates, evaluating the groundwater potential is critical, particularly because the only source of drinking water and irrigation for the community is groundwater. The objective of this report is to locate and identify probable groundwater basins in the upper Wadi Namous basin’s Ain Sefra area. GIS and RS were used to evaluate the parameters of morphometry and to demarcate groundwater potential zones by using eight different influencing factors, viz., geology, rainfall, height, slope, land cover, land use, and lineaments density are all factors to consider. The analytical hierarchical process (AHP) was used to give weightages to the factors, and definitions within each attribute were sorted in order of priority for groundwater potentiality. The major findings of the research were the creation of groundwater-potential zones in the watershed. The hydrogeological zone of the basin was assessed as follows: very poor (0.56%), poor (26.41%), moderate (44.72%), good (25.22%), and very good (3.1%). The groundwater recharge potential zones are concentrated in low cretaceous locations, according to analytical data. The groundwater potential regions were checked to field inventory data from 45 water locations to corroborate the findings. The qualitative findings and the groundwater inventory data agreed 77.78%, according to the cross-validation study. The produced groundwater potential map might substantially assist in the development of long-term management plans by enabling water planners and decision-makers to identify zones appropriate for the placement of productive wells and reducing investment losses caused by well drilling failures. The results of the study will also serve as a benchmark for further research and studies, such as hydrogeological modeling.
