在撒哈拉以南非洲，农民采用现有的、经过改进的技术是一个核心挑战。推广剂通常用于传播农业技术和技术。没有证据表明哪些活动和激励机制可以使推广服务为农民服务。在莫桑比克现有的推广网络中，我们比较了可持续土地管理(SLM)做法在经典培训和访问(TV)和(2)联系每个社区的农民(CF)中的传播情况。然而，该项目实施的扩展网络的结构并不一定保证从中心向农民提供信息。蒙古政府与世界银行和IFPRI的一组研究人员合作，将MSDVP作为一种学习工具，并设立了随机对照试验(RCT)，以测试向CFS提供集中、直接培训和基于业绩的激励措施，以促进农民采用可持续土地做法的有效性。评价的设计包括3个重叠的治疗部门：(1)经修订的电视节目；(2)指定更多妇女接受直接的可持续土地管理培训；(3)为中心提供额外的基于业绩的奖励。在村一级随机分配各种治疗武器(150个治疗，50个对照)，在地区一级采用有策略的程序。报告侧重于处理1，并评论了实施处理3所面临的挑战。
Farmers' adoption of existing, improved techniques is a central challenge in Sub-Saharan Africa. Extension agents (EAs) are commonly used to disseminate agricultural techniques and technologies. There is no evidence on what activities and incentive mechanisms can make extension services work for farmers. Within an existing extension network in Mozambique, we compare di usion of sustainable land management (SLM) practices in the classic training and visit (TV and (2) a contact farmer (CF) in each community. Yet, the structure of the extension network implemented by the project does not necessarily guarantee a ow of information from CFs to farmers. The GoM worked with a team of researchers from the World Bank and IFPRI to use the MSDVP as a learning vehicle and set up a Randomized Controlled Trial (RCT) to test the e ectiveness of providing a centralized, direct training and performance-based incentives to CFs in boosting farmers' adoption of sustainable land practices (SLM). The design of the evaluation consists of 3 overlaid treatment arms: (1) the revised TV (2) additional women are designated to receive direct SLM training; and (3) additional performance-based incentives for CFs. The various treatment arms were randomly assigned at the village level (150 treatment, 50 control), using a strati ed procedure at the district level. The report focuses on treatment 1 and comments on the challenges in implementing treatment 3.
