Sri Lanka has banned imports of palm oil and new palm plantations and told producers to uproot existing plantations in a phased manner. Coconut plantations will also be uprooted at a rate of 10pc to make way for rubber or other environmentally friendly crops each year.

Environmentalists say palm oil production has led to widespread deforestation and damage to ecosystems but whether the plants themselves are more environmentally damaging compare to other monocrop has been debated.
