Dehesa agroforestry systems occupy around 6 million ha in the Iberian Peninsula. Their economic and environmental sustainability depends on the maintenance of the extensive livestock farms which created this typical ecosystem. This work analyzes dehesa farms in the Extremadura region (SW Spain) using technical and economic indicators of 69 randomly selected holdings. Principal component analysis (PCA) allowed us to establish a valid model explaining 65.8% of the variance. The two principal components having most weight were Iberian pig production (explaining 20% of the variance of the model), and which ruminant species were raised on the farm (15% of the variance). A cluster analysis distinguished five types of farms: sheep farms at high and low stocking rates, beef cattle farms, wooded farms with mixed livestock, and farms with a high level of cropping activity. The most profitable farms were those with either high overall livestock density or a high level of Iberian pig production. While high stocking density has historically attracted high levels of subsidy, production of Iberian pigs was profitable because of the high value of the product. In the light of CAP reform, Iberian pig production seems the most readily sustainable type of farming for the dehesa system.

Food consumption is one of the most important areas to influence environmental sustainability since it is responsible for one third of a household's total environmental impact. However, many consumers are not completely aware of the association between their food consumption and the environmental consequences. Recently, some food companies have developed labelling schemes to help inform their consumers of the impact a specific food product has on the environment during its production. The main objective of this study is to uncover consumers' perceptions and attitudes towards these environmental labels and their impact on consumers' purchase decisions. In this paper, five sustainability labels, covering both ethical and environmental aspects, were chosen as examples. A focus group approach has been taken due to its adequacy to explore beliefs, perceptions and experiences. Four focus group sessions took place with 36 participants in total. The data has been analysed using a specific qualitative program (Atlas.ti). Finally, the findings were presented and discussed in four main sections explained throughout the manuscript: food purchase decision, social and environmental labels, information on labels and reasons for purchase, and lastly, willingness to pay for certified labels. The results of this study show that, although consumers have positive attitudes towards sustainability attributes in food products, constraints still remain that prevent their materialisation in their purchasing behaviour.

Nowadays, an increasing number of consumers are demanding more information and more direct contact with food producers in order to avoid the various intermediaries in the supply chain, thus improving food traceability and price transfer. This has led to the development of more direct (short) food supply chains (SFSCs). Although consumer preferences to use SFSCs rather than traditional (long) supply chains have been widely researched in the literature, this study brings a new approach with the use of social media sites to build online SFSCs. A focus group approach with a total of 32 participants was used in this study with the main objective to understand consumers’ awareness and acceptance of SFSCs. Special attention was given to the use of social media and electronic word of mouth (eWOM) as new approaches to support the creation of such alternative channels.

The study of consumers' preferences is of great interest in the beef sector, where the BSE crisis generated deep changes in the basic conditions of demand for meat and in the behaviour of consumers. Previous qualitative research showed that 'price', 'origin', 'production system' and 'labelling' were the main attributes affecting preferences for beef in Extremadura (SW Spain). The data were obtained by a survey carried out between February and April 2002 with a sample of 575 regular consumers of beef. Conjoint Analysis has been used to estimate the relative importance of those attributes and to determine the existence of consumer segments with similar preference profiles. Results show that the origin of the product is the most important attribute for the choice of beef, followed by quality labelling, production system and price. Three groups of consumers were identified through cluster analysis, according to their preferences for beef.
