Amélioration durable de l'élevage des petits ruminants au Liban :

Abstract : A survey carried out on 129 small ruminant farming systems (accounting for 5% of the national livestock) all over the Lebanese territory identified through a cluster analysis five different systems: (i) Zero-Grazing (15 to 95 head flocks of foreign goat breeds), with high inputs; (ii) Sedentary (100-400 head), grazing on communal or private rangelands around the village; (iii) Vertical Transhumance (mainly Baladi goat flocks), moving from low to high altitude depending on season; (iv) Horizontal Transhumance (mixed goat and sheep flocks), moving from 100 to 150 km in the plain; (v) Semi-Nomadic (flocks > 400 head), moving with all their family over 200 to 300 km. Farms sustainability assessment was carried out using a tool built on the IDEA method, which covers agro-ecological, socio-territorial and economical dimensions of sustainability. The multivariate statistical analysis of the 39 indicators showed that systems with diversified potential (presence of animals and plants), specially sedentary and horizontal transhumance, have high scores of sustainability and that economical return was higher in the vertical transhumance and zero-grazing systems in which dairy products are sold directly to the consumers. Improvement of these systems in Lebanon depends on the rehabilitation of rangelands, the improvement of the productivity of the local breeds, and the protection of the typical products on the market through labelling schemes. The history over ten years and the sustainability's trajectory was carried using 60 of these farms. This work typifies farms according to their sustainability and proposes tracks for progress.
