The rural non-farm. sector has traditionally been viewed as a low-productiv

away as a country develops. Recent years have seen a shift away from this
position towards recognition that the rural non-farm sector can, and often
does, contribute to economic growth, rural employment, poverty reduction, a

e literature on the conceptual and empirical underpinnings of this more rec

aper documents the size and heterogeneity of the sector, pointing to eviden
ce that in many countries the sector is expanding rather than declining. Th
e issues associated with measuring the sector's economic contribution are d
