Abstract
STARK, Fabien et al. Methodologies for evaluating agricultural and animal production systems.Part II: Energy efficiency (EMERGY), farms' trajectory and an example of a whole farm model (GAMEDE). Pastos y Forrajes [online]. 2016, vol.39, n.2, pp. 81-88. ISSN 2078-8452.
This paper is the continuation of the one published in Pastos y Forrajes, no. 1, 2016, in which the general bases of a selection of currently internationally available methodologies for the dynamic evaluation of production systems, are offered. This part describes the methodologies Integral Energy Evaluation (EMERGY) and Systems' Trajectory; and also a concrete example is provided of the application of the principles of these methods in the construction of an integral evaluation model of farming systems, called GAMEDE.
Keywords : Animal production; evaluation; quality of energy.
