In this study, 200 Norwegian dairy farms were analyzed over three years to compare greenhouse gas emissions, nitrogen (N) intensity, gross margin, and land use occupation between organically and conventionally managed farms. Conventionally managed farm groups were constructed based on propensity matching, selecting the closest counterparts to organically managed farms (n=15). These groups, each containing 15 farms, were differentiated by an increasing number of matching variables. The first group was matched based on geographical location, milk quota, and milking cow units. In the second match, the proportion of milking cows in the total cattle herd was added, and in the third, the ratio of milk delivered to milk produced and concentrate usage per dairy cow were included. The analysis showed that the conventionally managed farms (n=185) had higher greenhouse gas emissions (1.42 vs 0.98 kg CO2 per 2.78 MJ of edible energy from milk and meat, calculated as GWP100-AR4) and higher N intensity (6.9 vs 5.0 kg N input per kg N output) compared to the organic farms (N=15). When comparing emissions per kg of energy-corrected milk (ECM) delivered, conventional farms also emitted more CO2 (1.07 vs 0.8 kg CO2 per kg ECM). Furthermore, conventionally managed farms showed lower gross margins both in terms of NOK per 2.78 MJ edible energy delivered (5.8 vs 6.5 NOK) and per milking cow unit (30 100 vs 34 400 NOK), and they used less land (2.9 vs 3.6 m² per 2.78 MJ edible energy delivered) compared to organic farms. No differences were observed among the three conventionally managed groups in terms of emissions, N intensity, land use occupation, and gross margin.

Abstract
Ruminants, including sheep, contribute significantly to methane emissions, thus resulting in high emissions per kg of product. However, they can utilise plant material unsuitable for human consumption, thereby transforming it into valuable, protein-rich food. Grazing also preserves cultural landscapes and can contribute to carbon sequestration. Under¬standing the balance between these factors within the climate change context is crucial. This study inves-tigates the environmental impact of meat, milk, and wool production from sheep farming in Norway and Slovenia.

Balancing production and environment (ProEnv)
The ProEnv project aims to address the challenge of finding a balance between agricultural production and environmental impact in Europe. It will compare the two different approaches, "land spare" and "land share" and to evaluate them in their ability to achieve this equilibrium.

#Amazing grazing - bærekraftig kjøtt og ull fra sau som beiter i norsk utmark
Kjøtt og ull fra norske sauer kommer fra gårder med ulikt ressursgrunnlag, ulike driftsopplegg og ulik ressursbruk. I dette prosjektet skal vi undersøke sauebonden sitt driftsopplegg, forbrukeren sin innsikt, og rammevilkårene som både bonden og forbrukeren må forholde seg til. Hvordan kan produksjonen forbedres, og hvordan kan forbrukeren få mer kunnskap og nærhet til hva beitebruk bidrar med gjennom produktene?
