This paper introduces a collection of articles on 'Transnational livelihoods and landscapes'. We outline the analytical value of grounding political ecologies of globalization in notions of livelihood, scale, place and network. This requires an understanding of the linkages between rural people to global processes. We argue that the exploitation of these linkages can, under certain circumstances, result in new options and markets for rural people in marginal regions, even though many rural societies also confront serious political, environmental and economic challenges that likewise derive from globalization.
