CABI Book Chapter

Shifting cultivation and secondary succession in the tropics.

Book cover for Shifting cultivation and secondary succession in the tropics.

Description

The present book attempts to document and systematize findings on shifting cultivation on a pan-tropical basis, drawing on major findings in the literature in the last five decades. The current book examines the processes of secondary succession and soil fertility restoration under bush fallow within an integrative framework, and uses the core-periphery analogy to analyse the process and stages of...

Chapter 9 (Page no: 146)

Intensification of shifting cultivation.

This chapter discusses the various ways the system of shifting cultivation has been modified to make it a more intensive system of agriculture. Attempts to modify shifting cultivation include the integration of trees into farmlands to form agroforestry systems, enrichment of fallow vegetation with tree legumes or other species to enhance its soil restorative ability, and some practices that may be specific to certain areas, such as mound cultivation and composting. Different types of agroforestry practices which are specific to certain areas are discussed: Faidherbia (Acacia) albida-based system in the savannas of tropical Africa; the leguminous/commercial tree-based system in the Chittagong Hill Tracts of Bangladesh; fodder trees in bush fallow in the Philippines; the cassava-pigeon pea system in the Bas-Congo region of the Democratic Republic of Congo; maize cultivation intensification with soyabean in Zimbabwe; and hedgerow intercropping in south-eastern Nigeria.
