Agricultural intensification, through increased yields, and raising incomes, through enhanced labor productivity, are two dimensions prioritized for sustainable agricultural development. Prioritizing these two outcomes leaves labor intensity as a hidden adjustment variable. Yet, when agriculture is mainstay and the prospects of labor absorption in other sectors are scarce, the density of agricultural employment is central for livelihoods. We revise relationships of land and labor productivity and labor intensity with farm size, using standardized data for 32 developing countries. We show that labor productivity increases with farm size, while land productivity and labor intensity decrease with farm size nonlinearly. Technical efficiency increases with farm size. We further systematize the evidence on how, beyond the farm level, local contexts can be pivotal in choosing how to prioritize the dimensions of the trade-off space. Our findings contribute to debates on the fate of small-scale farmers, and call for contextualized decisions.
农业集约化通过提高产量和提高劳动生产率来增加收入,是可持续农业发展的两个优先重点。优先考虑这两个结果,使得劳动强度成为一个隐藏的调整变量。然而,当农业是支柱,而其他部门吸收劳动力的前景有限时,农业就业的密度对于生计就至关重要。我们利用 32 个发展中国家的标准化数据,修订了土地和劳动生产率以及劳动强度与农场规模的关系。我们表明,劳动生产率随着农场规模的扩大而增加,而土地生产率和劳动强度则随着农场规模的非线性增加而下降。技术效率随着农场规模的扩大而增加。我们进一步系统地阐述了在农场层面之外,地方环境如何在选择如何优先考虑权衡空间的维度方面起着关键作用的证据。我们的研究结果有助于讨论小农户的命运,并呼吁做出具体情况具体分析的决策。
