本文探讨了津巴布韦小农放弃保护性农业（CA）技术的决定因素。该分析使用了四轮平衡的面板，旨在监测CA通过农民谁参加了CA推广项目的调查。研究结果表明，在积极推广期间采用CA的农民中有很大一部分最终放弃了这种做法，在没有非政府组织（NGO）的支持下。有较多耕作经验、家庭规模较大和耕地较多的家庭不太可能停止使用保护性耕作。反过来，富裕家庭和干旱地区的农民更有可能停止使用CA。持续采用在穷人中更普遍的发现支持了CA是一种扶贫技术的说法。最后，我们发现，非政府组织的持续支持和放弃保护性耕作之间存在着强烈的、消极的和强有力的关系。这一发现表明，有必要改善支持机构，以确保农民继续使用保护性耕作作为一种提高生产力和可持续的耕作方法。
This paper examines the determinants of abandonment of conservation agriculture (CA) techniques among smallholder farmers in Zimbabwe. The analysis uses four rounds of a balanced panel from a survey aimed at monitoring CA adoption among farmers who participated in CA promotion projects. Findings indicate that a large share of farmers who had adopted CA during the period of active promotion eventually abandoned the practice in the absence of support from non-governmental organisations (NGOs). Households with more farming experience, bigger household sizes and a greater number of cultivated plots were less likely to stop using CA. In turn, wealthy households and farmers in the drier areas were more likely to stop using CA. The finding that persistent adoption is more prevalent among the poor, supports claims that CA is a pro-poor technology. Lastly, we find a strong, negative and robust relationship between continued NGO support and abandonment of CA. This finding suggests that improved support institutions are necessary to ensure that farmers continue to use CA as a productivity-boosting and sustainable farming method.
