“…However, there is more variability in GHG emissions per unit organic product, and studies have found higher, lower or equal emissions compared with corresponding conventional systems (Tuomisto et al 2012). This implies that there is a need to improve current organic practices to achieve higher productivity per unit of land and higher N use efficiency per unit product.…”

“…Regarding dairy production technology, organic farming was shown in a review conducted by Tuomisto et al [34] to be associated with-compared to conventional farming-higher eco-efficiencies (i.e., global environmental performance) for one impact category (energy use) and lower ones for a couple of others (land use, eutrophication potential and acidification potential). In terms of local environmental performance, Thomassen et al [13] found, for Dutch dairy farms, a lower N and P 2 O 5 surplus per ha for organic farming.…”

Factors Affecting Global versus Local Environmental and Economic Performance of Dairying: A Case Study of Swiss Mountain Farms

Improving the sustainability of the dairy food chain requires a simultaneous improvement in global and local environmental performance, as well as in the economic performance of dairy farms. We investigated the effect of different structural, farm management, socio-demographic, technological and natural-environment-related factors on the economic and environmental performance of dairying. Our analysis relied on a case study of 56 Swiss alpine dairy farm observations, for which cradle-to-farm gate life cycle assessments and farm accountancy data were combined. The data refer to the years 2006 to 2008. The effect of the selected factors on farms' economic and environmental performance was analysed by means of non-parametric statistical approaches. The results revealed the existence of some factors presenting synergies and several factors showing trade-offs in the enhancement of farm global environmental, local environmental and economic performance. More generally, the promotion of farm global environmental performance and farm economic performance was shown to be synergetic whereas the enhancement of farm global and local environmental performance turned out to be mostly antinomic. However, some factors, namely organic farming, higher agricultural education, silage-free milk production, and also, to a weaker extent, full-time farming, larger farm size and lower intensity of cattle concentrates use, showed a potential to bring simultaneous improvements in the global and local environmental performance as well as the economic performance of dairy farming. Policy-makers should be aware of the complexity of the joint improvement of farm economic and environmental performance and only promote factors capable of synergistically enhancing the environmental and economic performance of dairy farming.

“…O texto da New Scientist está em linha com diversos autores, como Tuomisto e colaboradores [18], que analisaram quase uma centena de artigos científicos sobre impacto ambiental de agricultura orgânica e convencional na Europa. Os autores verificaram que a agricultura orgânica causa menor impacto ambiental por unidade de área, porém seu impacto é maior por unidade de produto, tendo em vista a menor produtividade.…”
