“…Pests and diseases are reported for 13.7% of the cases and seem to represent a common and serious problem in all the five North African countries. This threat does not affect only palm trees (Idder et al 2015;Saidi et al 2013), but also other crops within traditional oases, such as wheat (Oumata et al 2020) or fruit trees (Sadraoui-Ajmi et al 2022;Zougari et al 2021).…”

Traditional oases represent unique forms of adaptation to extreme environmental conditions, developed through the centuries by local farmers to support their livelihood, combining different crops (date palms, fruit trees, vegetables and fodder) with livestock breeding. Despite their social, economic and cultural importance, these agroforestry systems are currently facing multiple socio-environmental threats. The aim of the paper is to investigate the variety of Ecosystem Services (ES) and the main threats related to traditional oases in Northern Africa through a systematic literature review. The search returned 257 relevant papers published from 2005 to March 2022, mostly focusing on Tunisian oases (37%), followed by Algerian (23%), Moroccan (19%), Egyptian (17%), and Libyan (4%). Provisioning Services, in particular Genetic diversity, agrobiodiversity and biodiversity, are the most cited ES (36% of the papers) followed by Cultural Services, mainly represented by Traditional knowledge systems, cultural heritage and sense of place (17%), while Regulating Services are less considered. Results highlighted that water related issues (desertification, drought, salinization or overexploitation) represent the main threat, followed by decrease of agrobiodiversity, primarily due to the spread of monocultures of commercial date varieties, and by social transformations (depopulation, traditional knowledge and cultural heritage loss). The literature review proved that traditional oases are still crucial for the livelihood of local communities since they still provide many ES. Local experiences related to sustainable development and tourism, or innovative solutions to valorize local products and byproducts, could be important for replication in other traditional oases to contribute to the wellbeing of local communities and to the preservation of these agroecosystems.

“…ANOVA sreveals that, non-significant results for the variety Deglet Nour (p = 0.200) and highly significant for Ghars (p = 0.000) (Tab.1). [22,23] report that the increase in electrical conductivity of a nutrient solution or water led to increasing fruit acidity and vice versa. In cases of salt stress, the inorganic ions will diffuse into the fruits, which cause an increase in their cation-ion rate.…”

The problem of salinity of irrigation water in palm groves has led us to conduct this study based on the comparison of the quality of dates Deglet Nour and Ghars from two farming systems in the region of El-Oued according to the EC irrigation water. Salt stress in El'Ghout causes in both varieties a regression of biometric characteristics, pH, EC, water content and dry matter, while total sugars are high. The dates of the farm are more voluminous, less acidic, with high ash content, dry matter and high electrical conductivity. According to standards Algerian of date classification reveals that the characteristics of Deglet Nour dates of El'Ghout are more damaged by the salinity of the environment. The two varieties of the farm have better characteristics than those of El'Ghout. It also appears that the salinity of water improves the sugar content of dates

“…The cultivation of the date palm like all plants is confronted with several phytosanitary problems, such as Fusarium oxysporumf.sp albedinis diseases and pests such as the yellow mite Oligonychus afrasiaticus, the white scale Parlatoria blanchardi and the carob moth Ectomyelois ceratoniae. This last is currently considered as the most formidable predator of dates and as the main constraint to exploitation [3], it causes considerable damage to the crop both which decrease the yield product and the quality of the fruit, and also affects the fruits storage [4]. To overcome this issue, various control methods intensely developed to reduce the rate of infestations of this pest such as chemical treatment [5].…”

The use of aqueous extracts as alternative solutions that significantly reduce to the damage caused by pests like Ectomyelois ceratoniae. This work presents in-vitro tests that are successfully applied to evaluate the ovicidal activity of four spontaneous plants aqueous extracts, as, Rosmarinus officinalis, Peganum harmala, Thymus vulgaris and Artemisia herbaalba againt the moth eggs. The results showed a highly significant effect for T. vulgaris and A. herba-alba, sometimes reaching 100%, followed by R. officinalis, then P. harmala which was not present any effect on this pest eggs. T. vulgaris and A. herba-alba showed a strong inhibition of egg hatching. It exceeds 93 % mortality for a concentration of 0.12 mL/mL. For R. officinalis at 0.18 mL/mL concentration present a 72% mortality. While at 0.12 mL/mL, the mortality was 40%. The lethal doses to inhibit 50 and 90 % of the eggs were estimated to confirm the efficiency of the aqueous extracts , stronger results shows, respectively (0.014 mL and 0.062 mL) from T. vulgaris and (0.019 mL and 0.069 mL) from A. herba-alba. This work originally explores the benefits of some kinds of plants that are largely available and inexpensive for the biotreatment of carob moth eggs.
