Abstract

ABSTRACT Applying a triple hurdle model to nationally representative farm household data from Zambia, this study examines determinants associated with three sequential crop production decisions: animal draught power adoption, minimum tillage ripping adoption, and the extent of hectares ripped. The correlated random effects estimator is also used to explore two dimensions of minimum tillage ripping adoption: changes in adoption within a household over time (within-household effect) and differences in adoption between households at a given time (between-household effect). Results reveal that age and gender of the household head, the head's level of education, household labour, hectares cultivated, ripper ownership, loan access, receiving conservation farming advice and distance to agricultural service providers are some of the key determinants associated with the three stages investigated using the triple hurdle model. The correlated random effects results demonstrate that while certain factors enhance or inhibit the expected value of hectares ripped within a given household, it is not always the case that these factors have a similar effect when the analysis is between households. This article highlights policy options to enhance ownership of rippers, support smallholder farmer access to loans, facilitate development of agro-dealer networks, and innovative approaches for disseminating conservation farming information to farmers.

赞比亚小农采用牛牵引的最低耕作法

本研究采用三障碍模型对赞比亚具有全国代表性的农户数据进行分析，研究了与三个连续作物生产决策相关的决定因素:采用畜力、采用最低耕作率和公顷面积。相关随机效应估计器还用于探讨最小耕翻采用率的两个维度:家庭内采用率随时间的变化(家庭内效应)和特定时间家庭间采用率的差异(家庭间效应)。结果显示，户主的年龄和性别、户主的教育水平、家庭劳动力、种植面积、开膛手所有权、贷款获取、获得保护农业建议以及与农业服务提供者的距离是使用三栏模型调查的三个阶段相关的一些关键决定因素。相关随机效应结果表明，虽然某些因素提高或抑制了特定家庭内的公顷砍伐预期值，但在家庭之间的分析中，这些因素并不总是具有相似的效果。本文重点介绍了提高开荒者所有权、支持小农获得贷款、促进农业经销商网络发展以及向农民传播保护农业信息的创新方法的政策选择。
