To do so, we use data from a survey carried out in 2010 for the specific purpose of analysing the environmental performance of 50 dairy farms in the Spanish region of Asturias. The survey contains information on nutrients balances and greenhouse gas emissions which is used to calculate environmental pressure indicators. Eco-efficiency is measured using data envelopment analysis. We analyse the influence of farmers’ socio-economic characteristics and attitudes in explaining these eco-efficiency scores using truncated regression and bootstrapping procedures. On average, the dairy farms are found to be highly eco-inefficient. Among our results, farmers that are younger, that plan to continue in operation in the foreseeable future and that participate more in training schemes are found to be more eco-efficient. Self-reported positive environmental habits are also reflected in actual eco-efficient performance. We quantify these potential gains in eco-efficiency through a simulation analysis based on the estimated model’s coefficients.
15 pages., The paper analyses characteristics of vertical relationships of organic supply chains with a specific focus on the processing and retailing sectors. The analysis takes into account different regions of the EU Mediterranean area. Data were collected through interviews using an ad hoc questionnaire. The survey was based on a sample of 306 firms, including processors and retailers. The analysis revealed that a relevant aspect for the processing firms of organic products concerns the guaranteeing of safety and quality levels for the products. The main tools to implement the quality management are based on the adoption of specific production regulations and quality controls. The premium price most frequently applied by processors ranges from 10% to 40% and similar values are revealed for retailers. The diffusion of supply contracts allows the vertical coordination between agriculture and processing firms in the organic supply chains. The main distribution channels for the processing firms are represented by specialised shops in organic products, direct sales and supermarkets.
