Última Less or More Intensive Crop Arable Systems of Alentejo Region of Portugal: what is the sustainable option? Rev. Econ. Sociol. Rural Marques,Carlos; Baptista,Fátima; Silva,Luis Leopoldo; Murcho,Dina; Rosado,Maurícia. Competitiveness of traditional arable crop system of Alentejo region of Portugal has been questioned for long. Discussion and research on the sustainability of the system has evolved on two contrasted alternative options for production technologies to traditional system. On the one hand reduced and no tillage systems aim to more extensive technical operations reducing costs and maintaining production, or even to increase it in the long run as soil fertility improves. On the other hand, input intensification using irrigation, as a complement in the last stage of crop cycle or always when needed, aimed to increase system production levels. To evaluate competitiveness and sustainability of arable crop system we evaluated traditional rotation technology and...
