| This paper presents results of an on-farm biodiversity assessment of 45 organic arable farms in eastern Austria (region Weinviertel). The core of the assessment method consists of 99 parameters concerning agricultural practices and semi-natural habitats and their impacts on genetic diversity, habitat diversity and species diversity of eleven indicator species groups. For each farm, a biodiversity performance score was calculated ranging from 0 to 100 %, where 100 % would be reached with the highest possible scores for all parameters. The biodiversity assessment of the 45 organic arable farms revealed big between-farm differences in the biodiversity performance (16.8 to 50.6 %; Ø 32.8 ± 6.1 %). While 32 farms for example achieved biodiversity scores > 40... |

| This contribution provides insights in methods and results from seven Austrian organic, alpine and grassland-based dairy farms, which were analysed concerning their ecological sustainability. The milk yield per area unit was found as an appropriate parameter to differentiate extensive from intensive dairy farms, which also allows for a rough estimation of LCA results. Two farms which were characterised as ‘alpine-extensive’ generally show advantages if they are related to units of area and also in terms of the biodiversity potential. Two farms in hilly regions (transition from alpine to lowland area) produce relatively high amounts of milk per hectare farmland and hence show good results for LCA indicators, if related to product units. Three alpine farms... |
