“…Many relevant papers focused on studying and testing different techniques to overcome the difficulties in germination, replication and cultivation of argan, both to promote its cultivation and to facilitate reforestation and restoration of the argan forest. Different studies aimed at selecting argan genotypes with high resistance and resilience to drought (Chakhchar et al 2017;Bouzoubaa et al 2006) and salinity (Aameur and Sipple-Michmer-huizen 2001; Tazi et al 2018) also in view of the possible climate changes that will affect the region in the future. Different authors agreed on the fact that ecotypes from inland areas seem to be more drought tolerant.…”

Argan tree is endemic of Moroccan arid regions, providing socioeconomic and cultural benefits since ancient times. This study identifies the emerging threats for the argan forest, and the opportunities related to the innovative uses of argan products and byproducts. Argan forest is facing pressure from overgrazing, demand for argan oil and nuts, and land degradation, despite its recognition as a UNESCO Biosphere Reserve and the inclusion in the FAO Globally Important Agricultural Heritage Systems (GIAHS) Programme. Innovative use and recycling of the waste deriving from argan nuts processing, offer promising opportunities to support a local bio-economy. Argan press cake can be used to integrate livestock feeding, to extract sudan dyes or to produce bioplastics. Argan nut shells can be used to produce environment-friendly and low-cost purifying materials and biochar, or as a source of bioenergy. Argan pulp can be used for bioethanol production or to obtain natural insect repellent. Despite these promising opportunities, the socio-economic impact of innovative uses is still limited. Local population is not sufficiently involved in management and development strategies. To support the sustainable development of local communities, it is necessary to promote a participative approach as well as training and product differentiation among argan women cooperatives.

“…It is also a bad indicator of the capacity of argan to overcome transplant shocks [29]. No significant effect of NaCl on argan was detected on the height/diameter ratio [62]. Regarding the photosynthetic activity of argan, it is generally not affected even under the conditions of water stress, which directly affects the photosynthetic activity of most of the plants [63].…”

“…Behavior and growth differ from region to region depending on the soil type and the climate [42]. Generally, height, diameter, leaf number and chlorophyll content of argan decrease with increasing NaCl dose, and the mortality rate increases [62]. A test of different substrates (peat, compost and potting soil) at different doses showed that the type, nature and composition of substrates play a key role in determining the length, diameter and dry weight of argan [29].…”

The argan tree, which is found in southern Morocco, is characterized by environmental, economic and nutritional benefits, but the growth of this tree is very slow. This makes it necessary to find methods to accelerate its growth. A pot experiment was conducted to evaluate the effects of biochar (BC) and bio-compost (CP) each applied at the rate of 0, 3 and 6% (M/M) on starting growth of argan in fine silty soil for sixteen months. Main stem length, diameter, durability ratio, total length of all stems and number of sprouted shoots were measured every two months with two photosynthetic measurements spaced five months apart for each argan seedling. Despite the strong signs of epigenetic sensitivity and genetic variability across the argan behavior of each treatment depending on the duration and environmental conditions of the crop and the large standard deviations marked in all the tests that were conducted on the argan, some treatments showed interesting results, even in terms of the interaction between climatic conditions, type of treatment and type of test. The argan plants which were grown in the substrate at 6% BC 3% CP showed significant results for all the growth parameters studied and throughout the test. This mixture marked an average water holding capacity (WHC) of around 0.66 g H2O/g dw; the argan seedlings showed the best perimeter average, which exceeded 2.7 cm in the last measurement, with a ratio (height/diameter) strictly less than 7, which removes any possible problem of argan filiform. However, argan plants from all treatments were not stable in the growth characteristics studied; each treatment has advantages and disadvantages regarding argan. Transplantation and monitoring in the field of argan seedlings that have had interesting results are strongly recommended to see if the good starting growth influences their development in the field or if it is a temporary effect.

“…Argan is an endemic species of Morocco that has adapted genetically to persist under arid climates with highly variable annual rainfall and increased soil salinization, which typically makes it a robust solution against desertification and land degradation [ 9 ]. However, studies have shown that salt stress significantly affects the overall growing parameters of argan [ 10 ]. There has also been a significant reduction in the natural distribution of argan trees, with the most exposed and vulnerable trees disappearing due to severe drought.…”

The use of saline water resources in agriculture is becoming a common practice in semi-arid and arid regions such as the Mediterranean. In the SmaCuMed project, the desalination of brackish groundwater (TDS = 2.8 g/L) for the irrigation of Argan trees in Essaouira, Morocco, to 2 g/L and 1 g/L (33% and 66% salt removal, respectively) using low-pressure reverse osmosis (LPRO) (p < 6 bar) and membrane capacitive deionization (MCDI) was tested at pilot scale. MCDI showed 40–70% lower specific energy consumption (SEC) and 10–20% higher water recovery; however, the throughput of LPRO (2.9 m3/h) was up to 1.5 times higher than that of MCDI. In addition, both technologies were successfully powered by PV solar energy with total water costs ranging from EUR 0.82 to EUR 1.34 per m3. In addition, the water quality in terms of sodium adsorption ratio was slightly higher with LPRO resulting in higher concentrations of Ca2+ and Mg2+, due to blending with feed water. In order to evaluate both technologies, additional criteria such as investment and specific water costs, operability and brine disposal have to be considered.
