鉴于低收入国家--特别是撒哈拉以南非洲国家--的农业生产力停滞不前，粮食持续不安全，人们对采用新技术及其对这些区域生产力的影响继续感兴趣。有趣的是，SSA的玉米和水稻出现了绿色革命的迹象，反映在发达地区的产量急剧增加的趋势中。为了提高作物产量和维持产量增长，最近的技术采用案例研究一致建议采用综合农场管理系统，特别是在南沙地区。另一方面，自2010年代以来，关于社会网络或农民对农民技术推广的研究越来越多。这些研究探索了比传统的公共部门推广方法更有效的推广系统。本文回顾了最近关于技术采用及其对生产力影响的案例研究，以及关于农业推广的研究，以确定共同的发现、缺点和主要遗留问题。
Given the stagnant agricultural productivity and persistent food insecurity in low-income countries - notably in sub-Saharan Africa (SSA) - there has been continued interest in the adoption of new technology and its impact on productivity in these regions. Interestingly, there are signs of Green Revolution in maize and rice in SSA, reflected in sharply increasing yield trends in advanced regions. To increase crop yields and sustain yield gains, recent case studies of technology adoption unanimously recommend the adoption of integrated farm management systems, particularly in SSA. On the other hand, since the 2010s, there have been increasing numbers of studies on social network or farmer-to-farmer technology extension. These studies explore more efficient extension systems than traditional public-sector extension approaches. This article reviews both recent case studies of technology adoption and its productivity impacts as well as studies on agricultural extension to identify common findings, shortcomings, and major remaining issues.
