Although a few studies consider the sustainability of animal farming systems along the three classical main pillars (economy, environment and society), most studies on pig farming systems address only one of these pillars. The present paper is the introduction to a series of companion papers presenting the results of a study undertaken within the EU-supported project Q-PorkChains, aiming at building a comprehensive tool for the evaluation of pig farming systems, which is robust to accommodate the large variability of systems existing in Europe. The tool is mostly based on questions to farmers and comprises a total of 37 dimensions distributed along eight themes: Animal Welfare, Animal Health, Breeding Programmes, Environmental Sustainability, Meat Safety, Market Conformity, Economy and Working Conditions. The paper describes the procedure that was used for building the tool, using it on 15 contrasted pig farming systems and analysing the results. The evaluated systems are briefly described and a short overview of the dimensions is provided. Detailed descriptions of the theme-wise tools and results, as well as the results of an integrated evaluation, are available in the companion papers. © 2014 The Animal Consortium.

The increasing wood energy demand could cause an important mobilization of forest resources and be the reason of the forest management sustainability. To assess this risk, it is necessary to determine precisely the availability of wood in the forest. The methods used to evaluate the resource and forest availability have improved, but, paradoxically, misunderstandings have arisen because the published results vary according to the methods, which require great attention to the explanations in support of figures published in different studies. Currently, harvest is still far from the total availability in forest wood, even if we consider only the technically and economically part harvestable. However, the objectives set in the forest, if realized, would lead to an exploitation of forests much more intensive, which raises the question of maintaining the fertility of forest soils. Research must thus work on solutions that allow the exploitation of forest products while maintaining a high level of productivity. © AgroParisTech, 2014.
