This PhD research dissertation was carried out in the framework of the Agricultural Transformation by Innovation, Erasmus Mundus Joint Doctorate Program (AGTRAIN; www.agtrain.eu), funded by the EACEA (Education, Audiovisual and Culture Executive Agency) of the European Commission. This program was implemented in six sister European universities, where in my case, it was in SupAgro Montpellier, France and Polytechnic University Madrid, Spain. My sincere gratitude, therefore, goes to the coordinators of the AGTRAIN program, Andreas de Neergaard and Ida Marie Krogager (University of Copenhagen, Denmark), Didier Pillot, Corinne Pickett, Gisele Andre and Madeleine Aidi (SupAgro Montpellier, France) and Ramón Zamorano (Universidad Polytecnica de Madrid, UPM, Spain) for their unreserved support in administrative and other issues.
