AB [EN] This paper presents a methodological proposal of new energy sustainability indicatorsaccording to a novel accounting that follows agroecological and ecological economics criteria. Energyoutput is reformulated to include manure and thus consider the contribution to fertilization madeby pastoral livestock farming to agroecosystems. Energy inputs calculations include the grazingresources. These new definitions and calculations allow for new formulations of the energy returnon investment (EROI) as measures of the energy efficiency of livestock farming systems (finalEROI and food/feed EROI). The environmental benefit of manure is estimated from the avoidedenergy cost of using this alternative to inorganic fertilizers (AECM). The environmental benefit ofgrazing is measured through the energy cost of avoiding cultivated animal feed (AECP) and itsimpact in terms of non-utilized agricultural area (ALCP). The comparative analysis of differentlivestock breeding systems in three pastoral dairy goat farms in the Sierra de Cádiz in Andalusia,southern Spain, reveals the analytical potential of the new energy sustainability indicators proposed,as well as the potential environmental benefits derived from territorial-based stockbreeding and,more specifically, grazing activities. Those benefits include gains in energy efficiency, a reduction ofthe dependence on non-renewable energy, and environmental costs avoided in terms of energy inextensive pastoral systems.
