Constrained to the Oasienne Production and Strategies of a Sustainable Development （Case of the Oasis of El Mahassen, Southwestern of Tunisia）

In the absence of all industrial activity, the oasienne agriculture represents the only advantageous economic speculation of the region. However, the agricultural soils support largest constraints, which are the salinization, the hydromorphy, and the exaggerated division of the parcels by successive inheritance what can provoke a decline and a reduction of the productivity. The sampling and the analysis of the irrigation water shows a net rise of the waters salinity, of the order of 5.25 g/L. The topographic measures made during this work serve to detect zones favorable to the accumulation of the salt layers. The object of this note is to treat these constraints differently by means of an empiric survey, all trying to establish some adequate recommendations.
