The Role of Land Use Consolidation in Improving Crop Yields among Farm Households in Rwanda
研究了卢旺达小农户的土地利用整合对农业产量的影响，发现整合仅对土地面积超过1公顷的农户有增产效果，且化肥和灌溉的使用能带来额外收益。
Relative to other developing regions, the role of land consolidation in increasing crop yields is poorly understood in sub-Saharan Africa. This paper examines the role of land use consolidation on agricultural productivity among smallholder farmers in Rwanda. Household-level data are used to estimate a fixed-effects model with matched control groups to mitigate selection bias. The study finds a positive association between land use consolidation and crop yields, but only among farm households with landholdings greater than one hectare, which is well above the average farm size in Rwanda. Findings also point to the importance of non-organic fertilisers and irrigation as there appear to be significant benefits associated with further increases in their use among the consolidated farms.
