This study utilizes recall data from smallholder farmers in selected provinces in Zambia to examine the role of social and institutional networks, as well as other farm and household factors in the adoption and diffusion of conservation agriculture (CA) technology. We employed a dynamic discrete-time hazard model to capture the time path to adoption. The empirical results show that conditional on several potentially confounding factors, conservation agriculture technology adoption and diffusion are positively and significantly influenced by farmers’ access to information from social networks and institutional networks like extension services. Adoption decisions are also found to be significantly influenced by age, education, market distance, as well as location fixed effects.

这项研究利用赞比亚部分省份小农户的召回数据来研究社会和制度网络以及其他农业和家庭因素在采用和推广保护性农业（CA）技术中的作用。我们采用了动态离散时间危害模型来捕获采用的时间路径。实证结果表明，在几个潜在的混杂因素的条件下，保护性农业技术的采用和传播受到农民从社会网络和体制网络（如推广服务）获得信息的积极和显着影响。还发现收养决定会受到年龄，教育程度，市场距离以及固定地点影响的显着影响。
