With the introduction of new, improved rice varieties and fertilizers after the 1940s, Sri Lanka lost much of its Indigenous rice varieties and traditional knowledge of Indigenous farming practices.

This was the traditional land use system, which was changed by British colonialists who…This article was originally published on Mongabay
