PRODUCTION AGRICOLE ET CHANGEMENT CLIMATIQUE: VERS UNE TRAGÉDIE DES COMPORTEMENTS PAYSANS À TIASSALÉ?

This article proposes an analysis of the major changes which assign the farmers behaviors to city of Tiassalé under the angle of the climatic changes these last decades. Indeed, the shift and instability characterize from now on the seasons and the calendar of agricultural practices. Late or early rains, prolonged dryness are as many climatic factors which influence at the same time the agricultural behaviors than the resulting production. All the agricultural system of the zone is upset and the farmers, disorientated do not control any more their temporal reference marks of agricultural activities. They try nevertheless to adapt to it to the means of alternatives offered by technical progress. The recourse on the one hand to the new varieties selected adapted to these climatic risks and, on the other hand of the use of agrochemical inputs to accompany the production constitutes their only guarantee of success in this changing environment. Consequently, the production and the productivity of the agricultural systems from a sustainable point of view became are a real challenge for the actors of the sector. All things considered, the future of the systems of production is played in these climatic deficits and changes. It is a future which rests from now on the adapters and the agrobiochemical regulators, whose techniques of use remain still groping and even worrying for the producers. Also, the tolerance levels of systems they are largely ignored in this context of overall changes
