土壤肥力综合管理是一套因地制宜的土壤肥力技术和改良的农艺做法，旨在提高土壤肥力、作物生产力和小农收入。虽然这套做法是针对具体地点的，但使用改良种子、有机和无机肥料是综合可持续森林管理的核心技术。ISFM主要与更高的投入和劳动力需求有关，但几乎没有证据表明这些投资是否在家庭层面得到回报。利用埃塞俄比亚两个农业生态区的玉米、小麦和画眉草种植农民的数据，我们评估了采用核心ISFM技术是否与家庭福利的变化有关，这些变化是通过家庭总收入、粮食安全和教育来衡量的。此外，我们还将家庭内部的资源分配决策视为福利结果的潜在驱动因素。采用逆概率加权回归平差法。结果表明，采用ISFM的核心成分，玉米，小麦或画眉草是与较高的劳动力需求，以及从这些作物中获得的收入在这两个农业生态区。然而，只有在一个农业生态区，它还沿着了家庭收入、粮食安全和入学率的提高。相比之下，在另一个地区，我们发现，三种作物中至少有一种的技术采用与从事其他经济活动的可能性降低有关，指向劳动力再分配效应。我们的结论是，农业创新的福利结果可以是异质性的，这取决于农民？收入多样化战略。
Integrated Soil Fertility Management (ISFM) is a set of locally adapted soil fertility technologies and improved agronomic practices promoted to enhance soil fertility, crop productivity and incomes of smallholder farmers. While the suite of practices is site-specific, the use of improved seeds, organic and inorganic fertilizers constitute core ISFM technologies. ISFM is mostly related to higher input and labor demand, but there is little evidence whether these investments pay off at the household level. Using data from maize, wheat and teff growing farmers in two agroecological zones in Ethiopia, we assess whether the adoption of core ISFM technologies is associated with changes in household welfare, measured by total household income, food security and education. In addition, we look into resource allocation decisions within the household as potential drivers of welfare outcomes. We use the inverse probability weighting regression adjustment method. Results show that adopting ISFM core components for maize, wheat or teff is associated with higher labor demand as well as income obtained from these crops in both agroecological zones. Yet, only in one agroecological region, it also goes along with enhanced household income, food security and school enrollment. By contrast, in the other region, we find that technology adoption for at least one of the three crops is related to a reduced likelihood of engaging in other economic activities, pointing towards labor reallocation effects. We conclude that welfare outcomes of agricultural innovations can be heterogeneous depending on farmers? income diversification strategies.
