Infrastructure and technology constraints to agricultural development in the humid and subhumid tropics of Africa:
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.
