The second approach is to try to encourage diversification to create multiple sources of income and employment, largely through small-scale enterprises. A third approach is to concentrate efforts in urban areas and rely on spread effects to pull rural areas along, using spatially blind policies. None of these approaches looks explicitly at the problems and opportunities for specific rural regions, and none has a focus on connecting various policy initiatives into a package that provides a co-ordinated and coherent approach. The remainder of this chapter seeks to outline competing themes in rural development in the form of policies centred on the promotion of single sectors (usually agriculture or primary commodities) and others on diversification (OECD, 2006).
