Agricultural technologies developed by national and international research institutions were not benefiting the rural population of Ethiopia to the extent desired. As a response, integrated agricultural extension approaches are proposed as a key strategy to transform the smallholder farming sector. Improving Productivity and Market Success (IPMS) of Ethiopian Farmers project is one of the development projects initiated by integrating productivity enhancement technological schemes with market development model. This paper explores the impact of the project intervention in the smallholder farmers' wellbeing.
To test the research hypothesis of whether the project brought a significant change in the input use, marketed surplus, efficiency and income of farm households, we use a cross-section data from 200 smallholder farmers in Northwest Ethiopia, collected through multi-stage sampling procedure. To control for self-selection from observable characteristics of the farm households, we employ Propensity Score Matching (PSM). We finally use Data Envelopment Analysis (DEA) techniques to estimate technical efficiency of farm households.
The outcome of the research is in line with the premises that the participation of the household in the IPMS project improves purchased input use, marketed surplus, efficiency of farms and the overall gain from farming. The participant households on average employ more purchased agricultural inputs and gain higher gross margin from the production activities as compared to the non-participant households. The non-participant households on average supply less output (measured both in monetary terms and proportion of total produce) to the market as compared to their participant counterparts. Except for the technical efficiency of production in potato, project participant households are better-off in production efficiency compared with the non-participant counterparts.
We verified the idea that Improving Productivity and Market Success (IPMS) of Ethiopian farmers' project has contributed for the input and out market integration and/or market oriented agricultural production. Overall, we argue that these can be seen as an experimental model with a promising potential to improve the livelihood of the poor. Furthermore, we suggest that it is worthwhile to employ integrated agricultural extension programs with further targeting in the developing world.
国家和国际研究机构开发的农业技术并未如预期那样让埃塞俄比亚农村人口受益。作为应对措施,综合农业推广方法被提议作为改造小农农业部门的关键战略。提高埃塞俄比亚农民生产力和市场成功率(IPMS)项目是通过将提高生产力的技术方案与市场发展模式相结合而启动的发展项目之一。本文探讨了该项目干预对小农福祉的影响。
为检验该项目是否给农户的投入使用、市场剩余、效率和收入带来显著变化这一研究假设,我们使用了通过多阶段抽样程序收集的埃塞俄比亚西北部200个小农的横截面数据。为控制因农户可观察特征导致的自我选择问题,我们采用倾向得分匹配法(PSM)。最后,我们使用数据包络分析(DEA)技术来估计农户的技术效率。
研究结果与以下前提一致,即家庭参与IPMS项目可改善购买投入的使用、市场剩余、农场效率以及农业总体收益。与未参与项目的家庭相比,参与项目的家庭平均使用更多购买的农业投入,并从生产活动中获得更高的毛利润。与参与项目的同行相比,未参与项目的家庭平均向市场供应的产出(以货币形式和总产出比例衡量)更少。除了土豆生产的技术效率外,项目参与家庭的生产效率比未参与家庭更高。
我们验证了埃塞俄比亚农民提高生产力和市场成功率(IPMS)项目有助于投入与市场整合和/或以市场为导向的农业生产这一观点。总体而言,我们认为这些可被视为一个具有改善贫困人口生计潜力的试验模式。此外,我们建议在发展中世界进一步有针对性地采用综合农业推广项目是值得的。
