This technique is often used in LEDC's such as Indonesia or other countries mostly in South-Eastern Asia, as this is the most profitable way to clean up the environment for crop farming.
Despite of the promise of Indonesian government they still continue to use this technique. This technique quickly disappeared during the introduction of market agriculture, however, in South Asia (this zone includes countries such as India) they have not yet adopted this practice. Villages that exist, for example, in Asia replant the trees to try to fix the environmental hazard. However, this technique of slash and burn is killing many forests, one of them being, for example, the Amazonas.
