Shifting cultivation can cause severe environmental damage primarily when *a. population exceeds environmental capacity through population increases. b. it upsets the local ecology thorough increased use of fertilizers.

Shifting cultivation, which is still prevalent in the uplands of eastern Bangladesh, contributes significantly to forest loss and is the main cause of land degradation. This paper presents the causes and consequences of shifting cultivation and its potential land use alternatives.

That is why attempts at finding viable alternatives to shifting cultivation have met with only limited success. There are several soil-related and climate-related constraints (Table 1) that must be alleviated. These constraints lead to severe problems of soil degradation upon conversion from shifting cultivation to mechanized intensive agriculture.

The style of farming depends on consumer preferences, site factors, such as soil and climate and situation factors as access to markets. Commercial.

Shifting cultivation causes a high national waste as it converts the green land into a barren land. The land takes many years to replenish just at the cost of providing yield for 2 to 3 years. It upsets the ecological balance as it disturbs many eco-systems of that region due to destruction of natural vegetation.

Of course, some traditional forms of shifting cultivation can also cause long-term environmental degradation. “Pioneer” shifting cultivation, for example, is a system in which new areas of forest are cleared for fields, allowed to remain under cultivation too long, and then abandoned in a degraded condition (Kunstadter et al. 1978). In northern Vietnam, Hmong farmers have converted large areas in the highlands to grasslands as a result of pioneer swiddening.

However, when shifting cultivation is analyzed as an agroforestry system, i.e., the use of trees is also taken into account, then the overall result of managing forest patches can lead to an enhancement of biodiversity (Berkes et al., 1995). For example, the Runa Indian managed swiddens in the Ecuador Amazon increase species diversity in 5-year-old fallows as compared to unmanaged fallows.
