Abstract

Enhancing farm productivity in Ethiopia through the adoption of Integrated Soil Fertility Management (ISFM) is crucial for bridging the gap between food demand and supply, while also ensuring the sustainability of agro-ecosystems. However, the synergistic effects of different types of technologies within ISFM remain inadequately understood. This study analyzes individual and combined impacts of adopting ISFM practices, specifically inorganic fertilizer and Soil and Water Conservation (SWC) practices, on net crop value and per capita food consumption expenditure. Using primary data collected from 781 plots in eastern Ethiopia, the study employs Multinomial Endogenous Switching Regression (MESR) to identify those factors associated with the adoption of these practices and evaluate their impacts on households’ welfare, while accounting for both observable and unobservable biases. The average treatment effects of adopting inorganic fertilizer and SWC practices either separately or in combination show that these practices result in improved net crop value and per capita food consumption expenditure. Interestingly, the combined impact of inorganic fertilizer and SWC practices on net crop value and food consumption expenditure is more than double when compared to adopting these practices separately. Moreover, our finding shows that the age and educational level of the household, irrigation use, and cultivated area are positively and significantly associated with the likelihood of adopting the combination of inorganic fertilizer and SWC practices. Therefore, encouraging and supporting farmers to adopt a combination of inorganic fertilizer and SWC practices will result in significant welfare gains.

土壤肥力综合管理方法对埃塞俄比亚小农福利的影响

通过采用土壤肥力综合管理（ISFM）提高埃塞俄比亚的农业生产力，对于弥合粮食需求和供应之间的差距，同时确保农业生态系统的可持续性至关重要。然而，ISFM中不同类型技术的协同效应仍然没有得到充分的了解。本研究分析了采用ISFM做法，特别是无机肥料和水土保持（SWC）做法对作物净价值和人均粮食消费支出的单独和综合影响。该研究利用从埃塞俄比亚东部781个地块收集的原始数据，采用多项内生转换回归（MESR）来确定与采用这些做法相关的因素，并评估其对家庭福利的影响，同时考虑可观察和不可观察的偏差。单独或联合施用无机肥和SWC的平均处理效果表明，这些做法可提高作物净价值和人均粮食消费支出。有趣的是，与单独采用无机肥料和SWC做法相比，无机肥料和SWC做法对作物净价值和粮食消费支出的综合影响超过两倍。此外，我们的发现表明，家庭的年龄和教育水平、灌溉使用和耕地面积与采用无机肥料和SWC组合做法的可能性呈正相关且显著。因此，鼓励和支持农民采用无机肥料和SWC相结合的做法将带来显著的福利收益。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
