This paper presents the results of such a spatial/historical analysis carried out in 1991/2 in Western Thailand by an interdisciplinary team of agronomists, remote sensing and social scientists. Two main transitional phases between three kinds of AS were identified and analyzed along the rapidly advancing cultivated frontier in Kanjanaburi province. A first major change occurred from a post-second world war system, still dominated by forest ecosystems because of low population and difficult access, to a second type of AS system based on the production of annual cash crops which is still dominating since the early seventies. Later, the recent appearance of a third type of AS in which perennial crops will play a major role was also diagnosed. In the near future, this could lead to the domination of a new AS, in which cultivated trees and animal husbandry would play more important functions. Elucidating these transitional phases of the regional agriculture led to the understanding of the extent, origins and mechanisms of the farmer differentiation process in the area under study. Such prior scientific knowledge on regional agrarian realities was used to implement on-farm research and development activities at farm and plot levels.
