Typologie des systèmes d’élevage au sud de Nâama : Cas des communes touchées par le barrage vert

يوسفي أحمد توفيق,  معروف عبد الرزاق, 
2024-03-18

Résumé: Résumé: Dans sa conception classique, le projet du barrage vert Algérien a montré ses limites et s’est percuté à des insuffisances d’ordre technique, et ce malgré l’importance particulière accordée à sa réalisation. Le diagnostic tiré à cet égard montre que la nouvelle vision de relance devra prendre en considération la composante socio-économique. Par ce travail, à travers une enquête sur le terrain, nous avons tenté d’étudier la typologie des systèmes d’élevage dans la partie sud de la Wilaya de Nâama, composée de six communes et touchée par le barrage vert. Après le traitement des données, nous concluons que les spécificités d’élevage des communes de sud touchées par le barrage vert, comparativement à celles du nord, peuvent contribuer à la réussite du projet par les caractéristiques suivantes : la sédentarité, l’association de l’élevage à l’agriculture, l’intégration de l’arbre fruitier et la nature juridique du foncier agricole détenu.

Mots clés: système d’élevage ; mode de vie ; barrage vert ; composante socio-économique ; wilaya de Nâama


Situation of Camel breeding in Algerian Southest - Biskra

Résumé: The study of camel breeding conduct in Biskra region (2019), with 30 breeders surveyed, high-lighted the importance of small breeders (25 heads, 46.67%). They are all most sedentary (66.68%) men aged 40 to 60 (75%), whose level of education does not exceed the primary level (37%). Ac-cording to the local population of the study region, this breeding is practiced in the majority of cases (80%) for multiplication reasons of the species among themselves. Reproduction occurs naturally during the period of struggle, which extends from November to April. The breeding age for females is 4 years old while it is more than 5 years old for males. A predominance of breeding camels (66.90%) of the El Hamra breed (85%) is noted, this breed is the most sought because of its famous skilfully Algerian Bernous and Kachabia. Dairy production and that of camel meat is weak in the economy of the wilaya, it is practiced only for self-consumption because of the free conduct of the herds and the weakness of spontaneous plants and the natural sources in water as well as the constraining climatic conditions of the current year

A number of proposed techniques for some date palm farming operations

Nourani Ahmed,  Kaci Ferhat, 
2024-03-12

Résumé: (1) Introduction: Date palm cultivation plays an important position in the Algerian agricultural production system. The palm tree requires very special care, particularly around the crown. Nowadays, farming operations are still carried out using manual labor and are therefore dan-gerous. For this reason, the use of machinery is absolutely crucial, especially in view of the shortage of skilled labour and the ever-increasing number of palm trees. (2) Methods: In our work, we carried out a detailed field survey of palm grovers. As a result of this survey, we developed a special pulley that makes it easier to lower the date bunches, and we also suggested using the rotovator instead of the hoe or the backhoe loader. (3) Results: These techniques could make cul-tivation much easier. (4) Conclusions: The results obtained from this study constitute an important achievement for the date palm sector in Algeria and may open up wide prospects for other research work in the field.

The date palm mite (Boufaroua) control constraints and their impact on the development of the date palm sector in Biskra, Algeria

Résumé: Date production is of strategic economic importance to Algeria but faces several challenges, especially from pests and diseases. The date palm mite, (Oligonychus afrasiaticus), commonly known as Boufaroua, ranks among the major pests in Algeria. It reproduces rapidly and cause significant losses. Numerous constraints hinder the control of Boufaroua which, consequently, have a direct economic impact on date production. This study reports on a survey of date growers and institutions acting in the control of this pest to identify the various constraints and subsequent impact on the date sector in Biskra. Pest control training programs, orchard sanitation awareness, detecting and management of first sources of infestation are recommended. The current study also, draws attention to the importance of engaging grower associations and other stakeholders to oversee the campaign, ensure effective monitoring of private operators (POs) and certify imple-mentation of agreed pest management procedures or protocols.

Cymbopogon schoenanthus essential oil’s effect on Bumblebees; Preliminary results

Bengouga Khalila,  Bettiche Farida,  Fadlaoui Haroun,  Tahachaouche Souad,  Salemkour Nora, 
2024-03-28

Résumé: Recently, it has become apparent that some pests especially insects can be controlled by exposure to small concentrations of the essential oils. What is unknown is whether these oils also affect pollinators. Our study on the effect of Cymbopogon schoenanthus (Poaceae) essential oil effect on the more adopted pollinator Bombus terrestris on greenhouse tomatoes crop in Biskra (arid re-gion of Algeria) is part of an FNR project ran by the Center of Scientific and Technical Research on Arid Regions. The aim of this research is to assess C. schoenanthus (Poaceae) essential oil toxicity on bumblebees at concentrations of 0 µl/ml, 20µl/ml and 1000 µl/ml under laboratory conditions. Results showed that concentrations of 20µl/ml were not harmful while pure E O of C. Schoenanthusis was detrimental. The experimentation suggested here presents further evidence partisan the use of conditioning techniques to assess the use of essential oils on tomatoes greenhouse pests.

Mots clés: Cymbopogon schoenanthus ; effect ; Bombus terrestris


Exploring the Contemporary Distribution of Saharan Livestock: A Case of the Oued Souf Region, Algeria

Résumé: To assess the current livestock situation in the Oued Souf region and map the distribution of po-tential species, we carried out a transect followed by an exploratory survey (Lhostev et al., 1993; Lesnoff, 2007; Boulassel, 2008). These investigations, carried out with 110 farmers over a period of eight months, revealed a remarkable diversity of livestock in the study area. Small ruminants dominate, accounting for 94% of total livestock across the different potential zones. Sheep, rep-resenting 58%, are mainly concentrated in Ben Guecha and Hassi Khalifa, while goats, representing 36%, are more widespread in Reguiba. Camels make up just 4% of the total livestock population. The Saharan herd has undergone a real transformation, evolving into a more diversified entity. This transformation is attributed to the resilience and ingenuity of breeders who have risen to the challenges posed by the Sahara's arid, harsh environment.
