| In this paper, we argue that there exist no significant direct links between human populations and their environments and that the intervening processes create the context within which land degradation occurs. We examine some of the intermediate mechanisms through which mounting demographic pressure leads to soil erosion and the depletion of soil fertility. The focus of attention is on set of variables defined in this paper as the structure of landholding (size of holdings, fragmentation/ dispersion, fragility, tenure, etc.). How demographically-induced changes in the structure of land-holding affect land management strategies (investments and land use) is key to understanding land degradation. Traditional perspectives on population and agricultural... |

| The horror of genocide and civil war have turned the world's attention to Rwanda over the last year. But before and beyond that conflict, there was hunger and the slow grinding poverty of small holder agriculture meeting with severe land scarcity and degradation. This report is about reversing the spiraling decline of the land and the economy in rural Rwanda. Three things conspire to accelerate this decline: unsustainable land use practices, insufficient non-farm employment, and rapid population growth. We focus on the forces behind productivity decline in Rwandan agriculture. This report examines how erosion, organic input use, soil conservation investments, use of fertilizer and lime, and land use strategies affect productivity. We then examine what... |

| A burgeoning recent literature emphasizes "livelihood" diversification among smallholder populations (Chambers and Conway 1992, Davies 1993, Ellis 1998, Bryceson 1999, Ellis 2000, Little et al. 2001). While definitions vary within this literature, the concept of livelihoods revolves around the opportunity set afforded an individual or household by their asset endowment and their chosen allocation of those assets across various activities to generate a stream of benefits, most commonly measured as income. This holistic perspective has the potential to enhance our understanding of the strategies that farm households pursue to ensure food and income security given the natural and economic environment in which they operate. Diversification patterns... |
