ABSTRACTMuch of our present day perception of African agriculture is still indirectly based on the coloured accounts of the early explorers and administrators. It involves an often very static conception of ‘traditional’ African agriculture. Not only does this fail to dojustice to the rich and dynamic history of African agriculture, it has also led to an inappropriate research and development paradigm which treats African agriculture as a disrupted equilibrial system that needs readjustment to return to an equilibrial and productivestate. A diachronic study of African agricultural history reveals that many of our preconceptions of African society and agriculture are invalid: agriculturists are not inert, but respond in innovative and dynamic ways to the perturbations of their natural and socialenvironment. It appears that their survival is not so much dependent on the establishmentof a fine‐tuned equilibrium, but rather on the dynamic responses to these external disturbances. It is very likely that the agro‐ecosystems in large parts of Africa function mainly as non‐equilibrial (unstable), but nevertheless persistent systems. This has importantimplications for development interventions and agricultural research. It requires a shiftfrom a synchronic approach to a diachronic approach that is firmly based on an understaning of
