Green Rcvolution technologies havc not bccn widely adoptcd in Africa. What arc the chanccs that they will play a major rolc in thc ncar futurc? This paper shows that thc cnabling infrastructurc, espccially rural roads and irrigation systcms arc not likely to be in place in the humid and sub-humid tropics of Africa in thc next 20-30 ycars. Conscqucntly a typology of thc more appropriate set of technology that is input and infrastructurc cficicnt, has high returns to seasonal labor and is sustainable is prcsentcd. Research institutions should be geared up now to producc them for usc in 10-20 years.RksurnP .-Lcs tcchnologics issucs dc la Rcvolution vcrte n'ont pas Ctc adoptccs a grande dchclle cn Afriquc. Dans quelle mesurc pourront-elks jouer un r61c majeur dans un prochc avenir'?
