Using a household and plot-level survey conducted in Ethiopia, this study analyses the difference in farmers' adoption of sustainable land management (SLM) practices between their rainfed and irrigated plots. The paper also investigates the varying influence of different types of irrigation water management systems and associated irrigation technologies on the adoption of SLM practices in irrigated plots. After controlling for heterogeneity among different irrigation water management systems and technologies, we found that access to irrigation play major role in enhancing farmers' motivation to adopt more SLM practices. Furthermore, the combined effect of irrigation water management system and irrigation technology on type and number of SLM practices adopted is quite varied and very significant. The evidence highlights that farmers adopt more SLM practices in their plots with pump irrigation compared with those plots where gravity irrigation is applied because pump irrigation systems enhance complementarities with SLM practices. Finally, the findings underscore that the type of irrigation water management and the irrigation technology applied play an important role in restoring degraded lands and maintaining soil fertility, even when farmers' adoption of irrigation was not explicitly triggered by concerns for soil health.

埃塞俄比亚灌溉农户采用多种可持续土地管理做法

本研究使用在埃塞俄比亚进行的家庭和地块层面的调查，分析了农民在雨养地块和灌溉地块之间采用可持续土地管理 (SLM) 做法的差异。本文还调查了不同类型的灌溉水管理系统和相关灌溉技术对灌溉地块采用 SLM 做法的不同影响。在控制了不同灌溉水管理系统和技术之间的异质性后，我们发现灌溉的获取在增强农民采用更多可持续土地管理实践的动机方面发挥着重要作用。此外，灌溉水管理系统和灌溉技术对所采用的可持续土地管理实践的类型和数量的综合影响是多种多样且非常显着的。证据强调，与应用重力灌溉的地块相比，农民在他们的泵灌地块中采用了更多的 SLM 实践，因为泵灌系统增强了与 SLM 实践的互补性。最后，研究结果强调，灌溉水管理的类型和所应用的灌溉技术在恢复退化土地和保持土壤肥力方面发挥着重要作用，即使农民采用灌溉并非出于对土壤健康的担忧。
