However, it is also a grossly misunderstood practice. Over time, fields are cultivated for a relatively short time, and allowed to recover, or are fallowed, for a relatively long time. The longer a field is cropped, the greater the loss of soil organic matter, cation-exchange-capacity and in nitrogen and phosphorus, the greater the increase in acidity, the more likely soil porosity and infiltration capacity is reduced and the greater the loss of seeds of naturally occurring plant species from soil seed banks. In some parts of the country of Sweden, there is some system of cultivation that was started till the year of 1920.

There followed a precipitous decline that left the great cities and ceremonial centres vacant and overgrown with jungle vegetation. Stable shifting cultivation systems are highly variable, closely adapted to micro-environments and are carefully managed by farmers during both the cropping and fallow stages. Shifting cultivation in general, is a system of farming in which fields are prepared by cutting down the natural vegetations. The land cropping cycle, the residence cycle and the size of the local territory are clearly interrelated. These new environments were then exploited to develop intensive, irrigated fields. In the middle of the nineteenth century, there were countries like the Europeans in Brazil and English settlers that were of the seventeenth century in Virginia of the U.S.A. they had also used this method of shifting cultivation.

Brazilian Perspectives on Sustainable Development of the Amazon Region, Vol. Shifting cultivation, another form of mountain agriculture, is prevalent in five countries of the eastern HKH region. The apparent discrimination against shifting cultivators caused a confrontation between FAO and environmental groups, who saw the FAO supporting commercial logging interests against the rights of indigenous people (Potter 1993, 108). Fields in established and stable shifting cultivation systems are cultivated and fallowed cyclically.

During the rest or fallow periods intervening between crops, the natural fertility of the soil is restored for renewed utilization in a subsequent period of crop growth. First, population growth in most pre-industrial shifting cultivator societies has been shown to be very low over the long term. The controversy over Boserup's proposal is in part over whether intensive systems are more costly in labor terms, and whether humans will bring about change in their agricultural systems before environmental degradation forces them to.

A mere 700 years later it reached its apogee, by which time the population may have reached 2,000,000 people. Environmental pressures are thus mediated through social relations. Rather they perceive an apparently chaotic landscape in which trees are cut and burned randomly and so they characterise shifting cultivation as ephemeral or 'pre-agricultural', as 'primitive' and as a stage to be progressed beyond.

(1961) Swidden agriculture and the rise of Maya civilization. This farming system has been widely disputed as environmentally destructive and economically unfeasible. Shifting and swidden cultivation is a food production system, which is very demanding on space-time in the settlement system and therefore allows relatively low population densities compared to other cultivation systems. Kirch, P. V. (1984) The Evolution of the Polynesian Chiefdoms, Cambridge University Press, Cambridge.

Eventually a previously cultivated field will be cleared of the natural vegetation and planted in crops again. In the tropical developing world, shifting cultivation in its many diverse forms, remains a pervasive practice. During fallow periods soil temperatures are lower, wind and water erosion is much reduced, nutrient cycling becomes closed again, nutrients are extracted from the subsoil, soil fauna decreases, acidity is reduced, soil structure, texture and moisture characteristics improve and seed banks are replenished.
