Systèmes de production basés sur des races locales de porcs et demande sociétale pour la fourniture de biens publics : le cas de la filière Noir de Bigorre

Abstract : Local pig breeds are frequently raised in extensive farming systems adapted to the local environment and the resources it produces. These farming systems tend to be less efficient than their intensive counterparts, but in exchange produce goods and services for society (biodiversity, clean air, landscape attractiveness, etc.). The supply of these public goods may not be guaranteed due to a lack of recognition of their market values, and policies that ultimately can put the future of these systems at risk. Economic valuation methods can measure the non-market benefits provided by these systems as an estimate of the social demand for their key features. Within the European Union TREASURE project, a choice experiment (CE) survey was applied to assess the social demand for relevant attributes of the Noir de Bigorre (NB) French regional pork chain, based on the local Gascon pig breed in an extensive system with the character of a public good. A valuation questionnaire was administered to 418 individuals, half of them located in the production area of NB chain. Results show that almost 40% of the respondents did not know or consume products from the NB chain. On average, guaranteeing the survival of the breed achieved the highest willingness to pay (112.37 €/household/year). Respondents are willing to pay 42.35 € to maintain an equal number of small and medium farms and 21.86 € to have feedstuff produced near the farms. Geographical availability and selling places of products contribute to a lesser extent to shape their preferences. Results show that social demand does exist to support survival of the breed and its extensive production system linked to local resources.
