The first chapter defines the tropics, and chapter 2 defines shifting cultivation and presents the basic features and types of shifting cultivation. The soil dynamics during cultivation and fallow period are discussed in chapters 3 and 4, respectively. The dynamics of fallow vegetation are presented in chapter 5, and the interrelationships. The status of chitemene shifting cultivation, in northern Zambia was investigated and reviewed. This paper presents results concerning (a) changes in soil nutrients under chitemene shifting cultivation, (b) the relationship between population density and deforestation and (c) how the chitemene shifting cultivation system has survived under conditions of overpopulation relative to the critical Cited by:
Mosaic landscapes under shifting cultivation, with their dynamic mix of managed and natural land covers, often fall through the cracks in remote sensing–based land cover and land use classifications, as these are unable to adequately capture such landscapes’ dynamic nature and complex spectral and spatial signatures.

Shifting Cultivation. Shifting cultivation is the most ancient system of agriculture in which soil fertility is restored by long periods of fallowing rather than by off-farm inputs of fertilizers and amendments, nutrients are recycled between natural vegetation and crops, and ecological balance is maintained by adopting diverse and complex cropping systems rather than monoculture.

The efficiency can be increased by decreasing the losses. To be sustainable, the system must of necessity be soil-restorative. Most soils under shifting cultivation are being depleted and degraded because of nutrient mining over a long period of time.

The current book examines the processes of secondary succession and soil fertility restoration under bush fallow within an integrative framework, and uses the core. Effective organic soil cultivation helps control weeds and produce healthy plants.
Aerating—or exposing the soil to air—is an integral part of the cultivation process. Cultivation can be essential in a nontoxic, integrated pest-management solution. Under shifting cultivation systems farmers clear primary or secondary forests, or both.
Shifting cultivators leave depleted land fallow for a period of time for soil regeneration, thereby accumulating secondary fallow Size: KB.
