Abstract

This contribution aims to assess agricultural production in energetic and economic terms taking the example of Switzerland. The concept of eco-efficiency is applied. From a methodological point of view, the maximal level of efficiency of energy input is analysed using multiobjective optimisation. From a limited number of alternatives, the economic and energetic efficient alternative is chosen that shows the highest sectoral income in relation to its energy input. The calculations show, that in Swiss plant production more room exists for efficient energy savings than in animal production. In Swiss plain regions, from an solely economic point of view, energy input is considerably higher than under the consideration of energetic aspects in the objective function. On the other hand, in the hill and mountain region, energy use shows a relatively high level of efficiency. Dieser Beitrag hat zum Ziel, die landwirtschaftliche Produktion am Beispiel der Schweiz sowohl aus energetischer, als auch aus ökonomischer Sicht zu bewerten. Dazu wird das Konzept der Öko-Effizienz angewandt. Methodisch wird der maximale Grad der Effizienz des Energie- Inputs mittels Mehrzieloptimierung untersucht. Aus einer begrenzten Anzahl von Varianten wird die ökonomisch und energetisch effizienteste Variante ausgewählt, welche das höchste Sektoreinkommen in Relation zum Energie-Input aufweist. Die Berechnungen ergeben, dass die pflanzliche Produktion in der Schweiz grössere Spielräume zur effizienten Energieeinsparung aufweist als die tierische Produktion. Der Energie-Input in der Schweizer Talregion ist aus rein ökonomischen Aspekten deutlich höher als unter zusätzlicher Berücksichtigung von energetischen Aspekten in der Zielfunktion. Demgegenüber weist der Energie- Input in der Hügel- und Bergregion einen relativ hohen Grad an Effizienz auf.
