“…[30] ascertained Saudi Arabia's sustainable water management practices; more precisely, the water resources, water safety, water environment, methods, practices, obstacles/challenges, and issues related to its execution. To create a technique for building forests, an experiment was carried out using the "drip irrigation + high ridge + salt tolerant plant" reclamation pattern ( [31]). To guarantee desalinization, it was crucial to keep SMP above −10 kPa in the first two years, and to sustain the salt balance and plant development in the third year, SMP had to be kept above −20 kPa.…”

This study examines the complex interplay between food security, climate change, population, water, and renewable energy desalination in five Arab countries: Morocco, Egypt, Jordan, Saudi Arabia, and the United Arab Emirates. Using a comprehensive econometric approach: an Auto-Regressive Distributed Lag approach (ARDL) and Vector Error Correction Model (VECM) technique spanning 1990–2022, to explore the short- and long-run dynamics of these relationships and identify causal linkages. The ARDL results reveal a mixed outcome. While renewable energy desalination capacity holds potential for enhancing food security in all countries, its impact depends on cost and government support. The cost of desalination negatively affects food security in most cases, highlighting the need for cost-effective solutions. Climate change poses a significant threat, particularly in Morocco, Egypt, and Jordan, but it may also offer unexpected opportunities for KSA and UAE. Population growth, unsurprisingly, strains food security across the region. Water scarcity emerges as a major challenge, especially for Jordan. The Granger causality tests uncover bidirectional relationships between renewable energy desalination, climate change, and water in Morocco and Jordan, suggesting their interconnected influence. In Egypt, population, water, and food imports drive the system, while KSA and UAE exhibit complex dynamics with renewable energy desalination and food imports acting as key drivers. Policymakers facing the complex challenge of food security in Arab countries should take note of this research’s multifaceted findings. While renewable energy desalination holds promise, its success hinges on reducing costs through technological advancements and government support, particularly in Morocco, Egypt, and Jordan. Climate change adaptation strategies must be prioritized, while recognizing potentially unexpected opportunities in regions like KSA and UAE. Additionally, addressing water scarcity through innovative resource management is crucial, especially for Jordan. Managing population growth through family planning initiatives and promoting sustainable agricultural practices are vital for long-term food security. Finally, the identified causal relationships underscore the need for integrated policy approaches that acknowledge the interconnectedness of these factors. By tailoring responses to the specific dynamics of each nation, policymakers can ensure effective interventions and secure a sustainable food future for the region.

“…Sus principales hábitats se ubican en suelos generalmente pedregosos de cerros, laderas y cañadas entre los 400 y 2,000 metros de altitud, aunque se encuentran en mayor abundancia entre los 1,400 y 1,800 metros de altitud (Aguilar-Murillo et al 2013). En la actualidad, el uso de plantas tolerantes a la salinidad puede ser una alternativa viable para enfrentar la problemática del aumento de suelos salinos en el mundo (Dong et al 2021).…”

Background. One of the classic land degradation problems that man has had to face is controlling, preventing, or improving soils affected by salinity. Objective. The objective of this study was to evaluate the physiological and morphometric response of Origanum vulgare L. plants subjected to five concentrations of NaCl (0, 50, 100, 150 and 200 mM NaCl). Methodology. The experiment was established in a completely randomized design with five treatments based on different concentrations of NaCl (0, 50, 100, 150 and 200 mM) with four replications per treatment. Each repetition consisted of 14 plants. The variables evaluated were fresh and dry weight of leaves, leaf area, fresh and dry weight of stem, stem length, fresh and dry weight, and root length, chlorophyll content a and b, relative water content and water potential. Results. The results showed that the fresh and dry weight of leaves, stem and root, foliar area, as well as the length of stem and root showed significant differences between treatments, they decreased as NaCl concentrations increased in the culture medium, as did the chlorophyll content "a and b". It is concluded that oregano plants have the capacity to absorb Na from the culture medium in 50, 100 and 150 mM of NaCl. Implications. The study makes the possibility to determine the tolerance of oregano to salinity, by subjecting the plants to different concentrations of NaCl and assessing whether it has the capacity to absorb Na+ from the culture medium. The study shows that it is possible to grow oregano in floating root hydroponic conditions, considering the advantages that this system offers, such as saving water and nutrients, being possible to obtain adequate yield using water of moderate salinity (50 mM NaCl) that represents an electrical conductivity of 5.8 dS m-1. Conclusions. All variables decreased as NaCl concentrations increased in the culture medium. Oregano showed the ability to absorb Na+ from the culture medium in 50, 100 and 150 mM NaCl.

“…Puccinellia distans has excellent salt tolerance, can grow widely in soils with a salinity of approximately 7-92 dS m À1 (Dashtebani et al, 2014), and has been used in Pb phytoextraction (Ghasemi et al, 2017). Astragalus adsurgens grows at a salinity of 0.6-8 dS m À1 (Dong et al, 2021;Qi et al, 2019), and is the dominant plant species in the lead-zinc mine tailings in Shaanxi Province, China (Ban et al, 2012). Thus, these three grasses exhibit differential tolerance to salt stress, adapt to heavy metal environments, and are suitable for the remediation of heavy metal-contaminated saline soils in arid and semi-arid regions.…”

Differential effects of arbuscular mycorrhizal fungi on three salt‐tolerant grasses under cadmium and salt stress

et al. 2022

Salt‐tolerant plants generally grow in salty conditions, and some of them are also tolerant to heavy metal stress. Arbuscular mycorrhizal fungi (AMF) can help plants withstand abiotic stresses. However, few studies have focused on the effects of AMF on the growth of salt‐tolerant plants in cadmium (Cd)‐contaminated saline soils. In this study, a greenhouse pot experiment was conducted to investigate the effects of AMF (Funneliformis mosseae) on growth, ion uptake, and Na+ and Cd translocation in three salt‐tolerant grasses (Leymus chinensis, Puccinellia distans, and Astragalus adsurgens) in a Cd‐contaminated saline soil. The regulation of genes by AMF in A. adsurgens was also explored by transcriptome analysis. The results showed that AMF increased the biomass of A. adsurgens but not that of L. chinensis and P. distans. AMF promoted phosphorus (P) uptake from soil and improved shoot K+: Na+ ratio, but it decreased shoot Na+ and Cd concentrations and their translocation rates in A. adsurgens. Transcriptome analysis showed that AMF upregulated the differentially expressed genes (DEGs) encoding cytokinins, which may be linked to the increase in shoot biomass in inoculated A. adsurgens, but downregulated the DEGs related to light harvest, suggesting avoidance of photodamage. AMF downregulated the DEGs in the pathways of the cell wall and those associated with antioxidant enzymes. These results suggest that AMF symbiosis in A. adsurgens effectively alleviates the Na+ and Cd toxicity of shoots. This study implies the potential to use salt‐tolerant grasses in association with AMF to rehabilitate the heavy metal‐contaminated saline ecosystems.
