Résumé : Within the policy and science community concerned with sustainable development, it is widely accepted that the first decades of the 21st century are a crucial turning point for the world community. Widespread poverty, growing inequality between and within a lot of countries, increasing pressures on vital ecosystems and ecosystem services combined with an intensive process of economic and cultural globalisation present enormous challenges for a world which aims for some form of sustainable development. Policy-makers, civil society organisations and scientists alike are looking for tools, concepts, approaches, theories… which can help in orienting policy in a way that a more sustainable development would become possible. It could be that the challenges of sustainable development are translated into equally important challenges with regard to the governance of sustainable development. Transition approaches - and among them ‘Transition management’ (TM) - have been increasingly popular alternative ‘tools’ in Northern Europe to conceive such shift in the governance of sustainable development. CONSENTSUS (“CONstruction of ScENarios and exploration of Transition pathways for SUStainable consumption patterns”) focuses on 2 crucial aspects – and moments - of Transition Management approaches: - Phase 1 was dedicated to an exploration of the significance and the conduct of scenario constructions identifying and discussing alternatives to the current food consumption regime. Phase 1 allowed - via a case study in the realm of food consumption - to identify and order the avenues towards a sustainable consumption mode of our societies; - during Phase 2, we worked on one of these prospectively identified transition pathways and tried to understand the mechanics, dynamics and governance of a specific ‘niche’ of food consumption patterns. The objective was, once that a particular transition pathway was identified, to comprehend how alternative consumption behaviour could be “up-scaled” (i.e. generalized).
