非洲尚未广泛采用绿色革命技术。他们在不久的将来发挥重要作用的可能性有多大？该文件表明，在未来20-30年内，非洲潮湿和亚潮湿热带地区不太可能建立有利的基础设施，特别是农村道路和灌溉系统。因此，提出了一种更适当的技术类型，即投入和基础设施效率高，对季节性劳动有高回报，而且是可持续的。研究机构现在就应该做好准备，生产出供10-20年使用的产品。
Green Revolution technologies have not been widely adopted in Africa. What are the chances that they will play a major role in the near future? This paper shows that the enabling infrastructure, especially rural roads and irrigation systems are not likely to be in place in the humid and sub-humid tropics of Africa in the next 20-30 years. Consequently a typology of the more appropriate set of technology that is input and infrastructure efficient, has high returns to seasonal labor and is sustainable is presented. Research institutions should be geared up now to produce them for use in 10-20 years.
