One-size-fits-all policies can therefore not provide adequate solutions to poverty and degradation problems. Sustainable rural development strategies in these areas need to focus on the potential for resource use intensification, based on a careful combination of local and regional measures. Various pathways for development can be identified for enabling rural households to exploit available comparative advantages. This article discusses the key components for the design and implementation of appropriate policies for enhancing sustainable development in less-favoured areas. Attention is focussed on the possibilities for simultaneously addressing poverty alleviation and sustainable natural resource management. An important strategy for improving targeting efficiency in situations of strong rural heterogeneity can be found in the promulgation of democratic decentralization and community-driven development programs. We provide a critical summary of the factors that determine the development potential and shape development pathways in less-favoured areas. (C) 2004 Elsevier Ltd 收起
