| This research has been carried out to study the sustainability of the Tunisian olive-growing farms and to compare the sustainability level of organic with conventional farms. A survey was conducted with 62 olive growers in the region of Sfax in Tunisia. First, a diagnosis of the situation of the farms was undertaken comparing between organic and conventional farms. Second, an empirical analysis was achieved to asses the sustainability of organic farms versus conventional farms following the French “IDEA” method developed by Vilain [1] 1. The “IDEA” indicators showed a greater ranking for the organic farms. The analysis indicated the sustainability of organic farming on the three scales adopted; ecological scale, through the soil fertility and reduction of... |

| In Tunisia, the extension of irrigated area is justified by its important role in the development and diversification of agricultural production. Nevertheless, the strong intensification of the agricultural activities may lead to the pollution of underground water resources due to an excess use of fertilisers and other chemical products. In fact, the high nitrate concentrations observed in some Tunisian irrigated areas, are related to the excessive use of nitrate fertilizers in intensive agriculture. The objective of the present study is to implement decision-making methods allowing a better combination of factors production by optimization of an economic objective and an environmental objective. This research is based on multi-criteria modelling through... |
