Abstract

[fre] De toutes les activités humaines conscientes, l'agriculture est de loin celle qui utilise le plus d'énergie soilaire. Les systèmes agricoles du monde développé sont, aussi, grandement dépendants des énergies que nous appellerons complémentaires (énergies « fossiles »). . Les méthodes permettant d'améliorer l'efficacité énergétique des systèmes agricoles sont nombreuses et il n'y a pas lieu de considérer qu'elles constituent un « pas en arrière », un « retour aux anciennes pratiques ». Le problème consiste à continuer à avancer mais dans une direction différente qui prenne en compte l'effet des prix élevés du pétrole sur 'la pertinence des indicateurs de productivité. . Beaucoup de ces modifications n'entraînent pas nécessairement des changements dans ce que 'l'agriculture produit mais simplement dans les méthodes utilisées pour produire. . Toutefois il ne fait pas de doute que Ja réduction la plus importante dans l'emploi d'énergie complémentaire en agriculture et l'augmentation la plus notable dans tous les aspects de l'efficience énergétique résulterait d'un déplacement de l'équilibre entre production végétale et porduotion animale — bien entendu avec une végétation accrue. [eng] Energy-saving types of agriculture - a critique of the mechanical and chemical orientation of farming - Of all man's deliberate activities, agriculture is by far the largest user of solar energy. . The agricultural systems of the developed world are also heavily dependent on the use of support energy (« fossil » fuels). . There are many ways in which the energetic efficiency of farming systems could be improved and there is no need to visualise this as « going back » or a return to earlier practices ». The problem is how to go forward but in a different direction, that takes account of the effect of high oil prices on the relevance of measures of productivity. . Many of these changes do not necessarily imply changes in what Agriculture produces, simply in the ways in which production is carried out. . However, there is no doubt that the biggest reductions in support energy use in Agriculture, and the biggest increases in all aspects of energetic efficiency, would result from a shift in the balance of crop and animal production (away from the latter).
