2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Le recours aux plantations d’arbustes fourragers aura lieu généralement si la dégradation a atteint le seuil d’irréversibilité. La plantation des arbustes est faite dans le but :
- Soit de combler un déficit dans le bilan fourrager annuel qui de la diffi-culté d »alimenter les troupeaux et qui se pose en général à la fin de l’année (fin d’automne et durant tout l’hiver).
- Soit pour la sauvegarde du cheptel en cas de sécheresse ou disette
- De conservation des eaux et des sols

2.2 Detailed description of the Technology

Description:

Les principaux arbustes fourragers utilisés au Centre – Sud de la Tunisie sont : Acacia cyanophylla, Atriplex nummularia et A. halimus, Opuntia ficus indica var. inermis si l’on peut considérer comme arbuste. Ces espèces ont donné des résultats spéctaculaires au Centre du pays elles ont par contre échoué dans le Sud en raison de l’aridité extrême. Ce n’est que ces dernières années que le recours aux espèces locales, plus adaptées aux conditions difficiles, comme Periploca angustifolia, Rhus tripartitum, Retama raetam a pris de l’ampleur.
Dans les parcours collectifs, les services forestiers se chargent à travers des chantiers de l’irrigation et de l’entretien des plantations. Au niveau des par-cours privés, l’Office d’Elevage et des Pâturages se charge d’apporter les plants et fournir des subventions au bénéficiaire qui se charge de toutes les opérations d’entretien et de protection.
L’exploitation par pacage direct ou recolte (cas du cactus) se fait après 3 à 4 ans pendant les périodes de soudure et de sécheresse.
