Mise en défens des parcours dégradés [Tunisia]

C'est une pratique qui consiste à soustraire successivement les terres de parcours à la vaine pâture, pendant une période plus ou moins longue. Cette méthode est le plus souvent appliquée dans les situations où la dégradation du couvert végétal pastoral n’a pas atteint le seuil d’irréversibilité. La mise en défens …

2. Description of the SLM Technology

2.1 Short description of the Technology

Definition of the Technology:

Les techniques de restauration sont généralement les plus conseillées si la dégradation n’a pas encore atteint le seuil d’irréversibilité et ce en raison de la facilité de leur application ainsi que leur coût relativement faible) Parmi les opérations de restauration, la mise en repos est la technique la plus couramment utilisée pour assurer la remontée biologique spontanée de la végétation originaire dégradée. Les résultats de la mise en repos réalisés dans plusieurs endroits arides où la dynamique de la végétation a connu un blocage, témoignent de l’efficacité de cette technique. Cette efficacité se traduit par une réinstallation et une régénération des espèces de haute valeur pastorale ayant disparu.

2.2 Detailed description of the Technology

Description:

La mise en repos se propose d’aider à l’initiation d’une dynamique ascendante des principaux types de parcours s’apprêtant à cette technique et d’asseoir une discipline de gestion basée sur le principe de la rotation ou du pâturage différé. Il s'agit d'un mode de gestion basé sur une utilisation régulière des sites retenus (abstraction faite de la nature de l’année), celle-ci alternant avec des périodes de récupération du couvert végétal de façon à aider à une remontée biologique de l’écosystème, tout en participant au soulagement d’autres sites soumis à une forte pression d’utilisation. Considérant les conditions écologiques du parcours cible, chaque parcelle mise en repos doit être mise hors usage pendant une période donnée en vue d’augmenter les chances de réhabiliter le stock en graines et/ou les souches des plantes pastorales les plus intéressantes et les plus affectées par la mauvaise gestion.

4. Technical specifications, implementation activities, inputs, and costs

4.1 Technical drawing of the Technology

Technical specifications (related to technical drawing):

Sur la base d’un certain nombre d’indicateurs comme la baisse du taux de recouvrement et la rareté des espèces de haute valeur pastorale comme les graminées pérennes, la mise en repos reste la technique la moins coûteuse et la plus efficace pour permettre la reconstitution spontanée de la végétation pastorale. Cette technique a permis d’obtenir des ré-sultats très encourageants particulièrement dans le sud de la Tunisie dans la mesure où son effet bénéfique aussi bien dans la conservation de la biodiversité et l’amélioration de la production pastorale est très net lorsque les conditions de son application soient réunies.
