Resumo(s)
In a globalised world that refuses progressively the externalization of any type of cost, especially
environmental cost, it's urgent to look at the agricultural sector with a broad perspective, incorporating
new decision variables and means of analysis. The agricultural activity is asked with increasing
insistence to adapt to new tasks, respecting all types of demands directed to its production systems.
This thesis involved the compilation of information on a broad spectrum of activities, resources and
products, and the creation of a model that would allow a multi-dimensional analysis of the agricultural
activities at national level, in order to respond to a possibly wide range of questions about economic and
environmental performance, numerically or spatially. The case-studies presented, aimed at
demonstrating the usefulness of the system in this multi-dimensional approach to agriculture, are four:
analysis of suitability to irrigation of the Portuguese territory; technical and economical evaluation of land
consolidation projects; the production of agricultural residues at national level; suitability of the Alqueva
perimeter for several bioenergetic crops.
