    Some observation on basic and applied research in shifting cultivation
    (Fosbrooke, 1973) Ahn, Peter M
    Previous papers presented at this seminar deal with problems of nomenclature and definition, with types of shifting cultivation, particularly in Africa, with the soil and the water aspects of the topic and with the reasons for shifting cultivation as far as they are at present understood. To some extent these papers themselves suggest areas where our knowledge is inadequate and where further research is required. To this extent they overlap with the present contribution. The papers presented serve to emphasize the great variety of practices included under the general term "shifting cultivation" and the variety of physical and human environments in which these practices are found. They suggest therefore the great and sometimes bewildering complexity of the soil and water aspects involved in any fundamental research on shifting cultivation. It is this many sided, complex aspect of the subject I wish to emphasis first.
