ENVIRONMENTAL AND SOCIO-ECONOMIC SUSTAINABILITY AND PERTINENCE OF ALTERNATIVE SCENARIOS FOR FOOD AND NON FOOD USES OF CEREAL RESOURCES IN WALLONIA (BELGIUM)

摘要

In Wallonia (Belgium), more than 60% of the arable cropped area is dedicated to cereals. The majority of cereal chains are classically turned towards animal feed and human food. Key opportunities for non food uses can however be considered as a sustainable development perspective. This can be achieved only through an exhaustive comparison of environmental and socio-economic performances of existing and potential valorization chains. Based on a comprehensive description of the Walloon cereal landscape, the project “Alternatives for Cereals – in short ALT-4-CER” aims firstly at elaborating scenarios for food, feed, fuel and fibre uses of cereal resources in Wallonia (so-called “4F” scenarios). Scenarios definition is supported by the consultation of all involved stakeholders of the cereals chain (producers, wholesalers, processors, consumers, and decision-makers) in order to ensure a further scientific approach based on realistic existing and potential cases. Scenarios evaluation will first focus on environmental and socio-economic aspects through Life Cycle Analysis methodologies development fed by regionspecific data adapted to the local context. Beside Environmental Life Cycle Analysis (E-LCA), a Social Life Cycle Analysis (S-LCA) methodology will be elaborated in order to grasp all 3 pillars of sustainable development. Environmental and socio-economic assessment methods will then be integrated thanks to multi-criteria analysis involving once again, as for scenarios construction, the stakeholders.
