Future of shifting cultivation is bleak. Discuss.

Explanation

These days, the biggest problem being faced by the shifting cultivators is of shortening cycles of jhum, which makes the entire practise unsustainable.
. Also there are several restrictions imposed by governments through forest acts etc., which hinder the free movement of tribes and practice of shifting cultivation
. Shifting cultivation is sustainable (only for self-consumption) in nature, hence it is unable to meet with the market demand and therefore there is no scope for it in the increasing globalized markets
. With the infiltration of non tribale in the tribal areas, tribals are adopting to modern agricultural practises which are more productive and environmentally sustainable.
. To support a small population, a huge land resource base is required, ultimately it leads to soil erosion and land degradation.
