Type of indicator
Quantitative
Relative dimension and aggregated criteria
Environmental sustainability: Biodiversity conservation: Animal breeds and crops diversity
Description
This indicator quantifies the diversity of cultivated species at the farm level, thus representing on-farm crop diversity. Farm biodiversity is expected to be enhanced by greater diversity of cultivated species per ha, as it results in higher potential of species shelter. This indicator is adapted from Last et al. (2014).
Unit
Number of crop species
Indicator interpretation
Lower values indicate larger negative impacts on the environment.
Scale definition
Based on Phocas et al. (2017), increasing the diversity of breeds in the dairy herd is hard to implement. The reference values suggested below are based on this fact and on the observed data of reproscope.
