Evaluation de la durabilité des exploitations laitières tunisiennes par la méthode IDEA

Abstract

Assessment of Tunisian dairy farms durability using IDEA method. The sustainability of 30 dairy farms was evaluated using IDEA method “Indicators of durability of farms”. Based on statistical methods (PCA, ACH), the three scales of sustainability (agro-ecologic, socio-territorial, and economic) have been characterized for the surveyed farms and has allowed to build groups. “Production system” typology is relevant for describing farms by agro-ecological and economical scales. The socio-territorial scale gives the limiting sustainability value for most farms. Inside this scale, the main way of progress relies on employment and services improvement (services, contribution to employment and collective work). Economically, sustainability is determined by the level of efficiency and depends on financial independence. Socio-territorial scale is the only one which is not linked to production system and is based on farmer’s way of life. On the other end, global sustainability evaluation of farm as well as creating collective references mean to be able to analyze links between the three scales of sustainability
