Cassava in shifting cultivation / Louise O. Fresco
Through a case study of cassava production in the Kwango-Kwilu region of central Zaire, this book provides a systems approach to agricultural technology development in Africa. In the region studied, cassava production has increased considerably over the last thirty years, keeping pace with or even surpassing population growth. Cassava, cultivated as a key component of a shifting cultivation system, allows for great flexibility in cultural practices. Much of the production growth can be explained by the expansion of cassava onto marginal soils, its increased presence in crop rotations and associations and the reliance on female labour. However, cassava yields have at the same time declined and the shifting cultivation system is breaking down. Research on cassava is discussed with a view to determining strategies for agricultural technology development. This study is of particular interest for its method of analysis. It draws on ecological system analysis and farming systems research, presentina a systems framework which allows the integration of technical and socio-economic aspects of crop production Cassava in Shifting Cultivation Louise O.
