In a context of increasing variability of weather conditions and prices, robustness is becoming a required characteristic of farming and cropping systems. We propose and test an indicator of cropping systems robustness based on gross margin variations. The method probably leads to underestimate gross margin variability because of the input data, the indicator appeared sensitive. However, it allowed to identify the variability of the major variation factors and, above all, to evaluate ex-ante several alternative cropping systems in a test loops design process. The method will be tested on several arable cropping systems besides other tools to forecast yields variability.

Abstract
In a context of increasing variability of weather conditions and prices, robustness is becoming a required characteristic of farming and cropping systems. We propose and test an indicator of cropping systems robustness based on gross margin variations. The method probably leads to underestimate gross margin variability because of the input data, the indicator appeared sensitive. However, it allowed to identify the variability of the major variation factors and, above all, to evaluate ex-ante several alternative cropping systems in a test loops design process. The method will be tested on several arable cropping systems besides other tools to forecast yields variability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
