摘要

本研究旨在评估水土保持干预措施对小农家庭生计的影响,包括家庭收入和生产力。为了实现这一目标,2010年从120个样本受访者(50个SWC项目参与者和70个非参与者)中收集了主要数据。描述和推理统计(逻辑回归)和倾向得分匹配(PSM)模型被用来解决既定的目标。配对结果前结果变量的平均差异分析表明,SWC实践被调查家庭的平均作物总产量为29.10和27.80分/公顷,研究差异为1.30分/公顷。与此同时,参与SWC计划的农户的年总收入分别为33,903美元和33,808.40美元。除家庭性别外,市场信息、耕地数量、教育程度和农场经验对家庭妇女参与SWC的概率有显著的正向影响,在10%的预期耕地在5%的水平上。治疗效果分析的名义结果表明,由于SWC程序,对考虑的两个变量都有积极影响的迹象。然而,作物产量和家庭总收入的变化在统计上无法证明是合理的,因为在这些变量方面,两组之间没有统计学上的显著差异。可能的原因是SWC计划不是短期性质的,影响是随着活动的增加和加强而逐渐实现的。

Impact of Soil and Water Conservation on Household Income in East Shoa Zone of Oromia
This study was conducted to assess the impact of Soil and Water Conservation (SWC) intervention on the livelihood of smallholder farm households in terms household income and productivity. To meet this objective primary data was gathered in 2010 from 120 sample respondents (50 SWC program participants and 70 non-participants). Descriptive and inferential statistics (Logistic regression) and propensity score matching (PSM) models were used to address the stated objectives. The analysis of mean difference in outcome variables before matching result indicated that the mean total crop yield for SWC practiced respondent households is 29.10 and 27.80 quintal/ha having 1.30 quintal difference in the study. In the meantime total annual crop income of households who participated in SWC program was 33,903 and 33,808.40 birr. Except sex of the household, Market information, amount of land cultivated, Education and farm experience influenced the probability of HH participation in SWC positively and significantly at 10% expect land cultivated at 5% level. Nominal results of analysis of treatment effects indicate that there was a sign of positive impact on both of the variables considered due to SWC program. However, the changes in crop productivity and gross household income could not be statistically justified as there was no statistically significant difference between the two groups in terms of these variables. The possible reason could be that SWC programs are not short-term nature and impacts are to be realized gradually with increased adoption and intensification of activities.
