Shifting cultivation
The present shifting cultivation system with short fallow in the Chittagong Hill Tracts has accelerated erosion, land degradation, deforestation, and impoverishment of tribal people in CHT. If the present state of degradation is continued, most of the areas under shifting cultivation will be severely degraded and the future generations will face more difficulties to eke out their livelihoods on further degraded land. Although there is some scope for shifting cultivators to leave the degraded fields and move to other areas. It is estimated that on average eight hectares of land is necessary for the sustenance of a family in the Chittagong Hill Tracts. If this ratio is adopted, 1, 240, 000 ha land is required to sustain the present population; however, the total land available, excluding the reserve forest, is 928, 000 ha. Shifting cultivation, therefore, cannot fulfill even the subsistence requirements of the people. In such a situation, either large non-farm employment opportunities need to be created or more productive land-use systems need to be developed and adopted. Given the sluggish growth of the economy, there is limited scope for generating adequate non-farming employment opportunities in the near future. It is, therefore, imperative to replace the present shifting cultivation system with more productive and sustainable land use systems to enable people to secure their livelihoods.
