Abstract

The existing literature acknowledges the benefits of beekeeping as a livelihood diversification strategy and income source for farmers across the world. However, the impact of beekeeping on income at household level has rarely been quantified. Furthermore, the few existing studies provide conflicting evidence and the methods quantifying the impact of participating in beekeeping are not rigorous. In this study, we identify key determinants of such participation and quantify the impact of beekeeping on household income. We use a cross-sectional data set collected from 392 randomly selected households in north-western Ethiopia, employing the endogenous switching regression model with estimated treatment effects. Unlike the methods used by previous studies, the approach adopted here enabled the control of observed and unobserved heterogeneities that affect not only the decision to participate in beekeeping, but also income differences among households. The results show that there are important differences between beekeepers and non-beekeepers in terms of their skills and resource endowments. After these differences were controlled for, beekeeping participation was found to increase income by 3,418 Ethiopian Birr (ETB) per person, namely a 51% increase. Furthermore, it was estimated that households not participating in beekeeping could have increased their income by ETB 442 per person (an 11% increase) had they become beekeepers. These findings indicate that income gains from beekeeping participation are 22-44 percentage points higher than benefits reported by previous studies. Capitalising on the existing beekeeping policy, targeted beekeeping extension to farmers could contribute to closing gaps in skills and resource endowments and, hence, minimising differences in income.

摘要

现有文献认可养蜂作为一种生计多样化策略以及全球各地农民收入来源的益处。然而,养蜂对家庭层面收入的影响却鲜有量化。此外,现有的少数研究提供了相互矛盾的证据,且量化参与养蜂影响的方法并不严谨。在本研究中,我们确定了这种参与的关键决定因素,并量化了养蜂对家庭收入的影响。我们使用了从埃塞俄比亚西北部随机选取的392户家庭收集的横截面数据集,采用具有估计处理效应的内生转换回归模型。与先前研究使用的方法不同,此处采用的方法能够控制那些不仅影响参与养蜂决策,还影响家庭间收入差异的可观察和不可观察的异质性。结果表明,养蜂户和非养蜂户在技能和资源禀赋方面存在重要差异。在控制了这些差异之后,发现参与养蜂使人均收入增加了3418埃塞俄比亚比尔(ETB),即增长了51%。此外,据估计,未参与养蜂的家庭如果成为养蜂户,人均收入本可增加442埃塞俄比亚比尔(增长11%)。这些发现表明,参与养蜂带来的收入增长比先前研究所报告的收益高出22 - 44个百分点。利用现有的养蜂政策,有针对性地向农民推广养蜂技术,有助于缩小技能和资源禀赋方面的差距,从而减少收入差异。
