Furthermore, ruminants have been identi fi ed as a signi fi cant source of GHG emissions. In this study, a whole-farm optimization model is used to assess the socio-economic and environmental performance of the dairy sheep farming activity in Greece. The analysis is undertaken in two sheep farms that represent the extensive and the semi-intensive farming systems. Gross margin and labour are regarded as socio-economic indicators and GHG emissions as environmental indicators. The issue of the marginal abatement cost is also addressed. The results indicate that the semi-intensive system yields a higher gross margin/ewe (179 €) than the extensive system (117 €) and requires less labour. The extensive system causes higher emissions/kg of milk than the semi-intensive system (5.45 and 2.99 kg of CO2 equivalents, respectively). In both production systems, abatement is achieved primarily via reduction of the fl ock size and switch to cash crops. However, the marginal abatement cost is much higher in the case of the semi-intensive farms, due to their high productivity. 17 pp. LOMv1.0 creator LOMv1.0 publisher LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2013 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Dairy sheep farming Mathematical programming GHG emissions Socio-economic performance Environmental performance Abatement cost http://irakleitos2.aua.gr/sites/default/files/Sintori%20et.al_.%20%282013%29%2C%20Evaluating%20Socionomic%20and%20Environmental%20Sustainability.pdf 681485 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/2800/2/2800_Sintori%20et.al_.%20%282013%29%2c%20Evaluating%20Socionomic%20and%20Environmental%20Sustainability.pdf Chapter 15 Book: Methods and Procedures for Building Sustainable Farming Systems (pp. 219-235) URI http://hdl.handle.net/10795/2800 LOMv1.0creator 2016-04-21T08:57:39Z LOMv1.0validator 2016-04-21T08:57:39Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
