Towards the real green revolution? Exploring the conceptual dimensions of a new ecological modernisation of agriculture that could 'feed the world'

The challenge to produce enough food is more urgent than ever. We argue that the dominant food regime has responded to this challenge by a 'narrow' ecological modernisation process within agriculture which may decrease environmental effects to a certain extent, but also causes new negative side-effects and exposes some important missing links. In this paper we explore what might be a 'real' ecological modernisation process, including social, cultural, spatial and political aspects. The central question concerns: is there evidence in practice that agro-ecological approaches can contribute to the future demand for food production, especially in developing countries? We illustrate this by describing examples from Africa, Brazil and China, showing a rich variety of such approaches in agricultural practices. Our conclusion is that agro-ecological approaches could significantly contribute to 'feeding the world', and thereby contribute to a 'real green revolution'; but that this requires a more radical move towards a new type of regionally embedded agri-food eco-economy. This is one which includes rethinking market mechanisms and organisations, an altered institutional context, and is interwoven with active farmers and consumers' participation. It also requires a re-direction of science investments to take account of translating often isolated cases of good practice into mainstream agri-food movements. (C) 2011 Elsevier Ltd.
