Abstract

[fre] L'analyse énergétique, qui comptabilise en entrée les énergies non renouvelables, en sortie l'énergie brute des produits de l'exploitation agricole, procure-t-elle des indicateurs de développement durable ? A partir d'exemples, il est montré que, en simplifiant la complexité tout en la quantifiant, l'efficacité énergétique révèle l'autonomie de l'exploitation, son recours aux ressources locales et aux énergies non renouvelables. Par ailleurs, on constate que les productions végétales ont de meilleures efficacités énergétiques qu'il y a 20 ans et que l'analyse énergétique est appropriée pour comparer différents itinéraires techniques d'une production donnée, ainsi que pour l'évaluation interne de l'exploitation. [eng] Sustainable development and energy balance of farms . Does the energy balance of farm, in which are accounted non-renewable energy incorporated into farm inputs and gross energy of the products, provide indicators of sustainable development ? On the basis of examples, it is shown that, in simplifying and quantifying complexity, energy efficiency reveals farm autonomy, its utilization of local ressources and non-renewable energies. Furthermore, it is pointed out that: better energy efficiencies are obtained in plant production than 20 years ago ; energy analysis is relevant to compare different management sequences of a given crop or animal product and to provide an internal assessment of the farm.
