Impact on Agricultural Sustainability of Maghreb Countries
This paper is aimed at making the diffusion of the technological innovation and their role in affecting the agricultural sector in the three-sided (social, economic and environmental), a hand, it can participate to resolve problems of the agricultural sector: the effects of the climatic changes, the farming exodus and the migration and the problems of poverty. The theoretically and empirically studies analyze the mechanical innovation role in improving agricultural sustainability through the impact of mechanization on agricultural productivity, CO2 emission and demographic growth for a panel of three Maghreb countries (Algeria, Morocco and Tunisia) during the period 1999-2012. By using simultaneous equations, the authors' finding that mechanical innovation cannot achieve the purpose of sustainable development in the agriculture sector in the Maghreb countries through the negative impact of mechanization and research and development on agricultural productivity.
