ECOALIM : une base de données des impacts environnementaux des matières premières utilisées en France pour l’alimentation animale

Consulter le resumé

L’alimentation animale contribue fortement aux impacts environnementaux de l’élevage, notamment au changement climatique (Gerber et al., 2013). Estimer les impacts des aliments utilisés dans les productions animales apparaît donc primordial pour pouvoir raisonner les pratiques d’alimentation capables de réduire ces impacts. Différentes bases de données d’impacts des matières premières (MP) utilisées en alimentation animale sont disponibles en Europe et aux Etats-Unis. Elles fournissent des valeurs moyennes, issues de statistiques internationales et calculées par Analyse du Cycle de Vie (ACV), pas toujours adaptées aux contextes locaux. L’objectif de la présente étude était de développer une base de données des impacts environnementaux des MP utilisables pour l’alimentation animale en France, tenant compte des itinéraires techniques des MP françaises, des origines des MP étrangères et de leurs procédés de transformation, avec une méthodologie harmonisée.

Characterisation of the pig systems panel for the production of environmental data in the program Agri-BALYSE

Consulter le resumé

The program Agri-BALYSE is a French initiative which aims to develop a public LCI-database of French agricultural products by the end of 2012.This database has two goals: (1) it will provide data to set up environmental labeling for consumers; (2) it will also include environmental assessments of different contrasting production systems which will be more useful for the R&D and the identification of action levers. Pig production/breeding is one of the agricultural products which is covered by the Agri-BALYSE-database. Given the fact that there exists wide variety of pig production systems in France, it has been necessary to choose the best panel of pig production/breeding systems in order to answer to the different objectives of the project. Actual representativeness of production systems was an important selection criteria but not the only one. Emphasis was given also to future representativeness as well as social desirability and agricultural practices. Three systems were defined to provide data for the environmental labeling: a national average standard production system, an organic production system as well as a pig system “fermier label rouge”. Four other systems have been selected to analyse the incidence of specialisation levels and feed strategies which are considered to be the most important action drivers. The chosen systems are qualified concerning their adaptability to the different uses by giving their actual and future representativeness, analyzing if the main levers of action are considered, considering system which are wanted by society. The final definition of the production system has also to consider if date and information are available and to see if it is (or will be) possible to trace system characteristics to the kilogram of pig.

Environmental and socioeconomic references of French conventional pig systems

Consulter le resumé

This study aims to produce multicriteria environmental references (using Life Cycle Assessment, LCA) associated with socioeconomic indicators for different types of pig units representative of the dominant French standard production systems. Eight systems are assessed, discriminated according to the size, the degree of specialisation and the location of the pig unit, the slurry management and the pig feeding strategy. The results are expressed per kilogram live pig produced and the LCA boundaries include the production and the supply of inputs, the production of buildings, the pig breeding and the management of slurry. The references bring a socioeconomic and environmental photography of the performance of the existing pig production systems and their variability between and within systems. The environmental results allow identification of the most strategic and easily attainable options of improvement. The effect of different improvement strategies are indentified in connection with feed formulation, improvement of animal performance, and the implementation of the recommended good environmental practices. The socioeconomic indicators of the systems show the various levels of access to the control levers of action.
