The hardy and multipurpose neem tree holds tremendous potential in sustainable farming systems across the world.

An article on Food Tank outlines the many uses of neem tree (Azadirachta indica), including as a natural pesticide, windbreak, source of fodder, fertilizer and traditional medicine, and in providing shade for livestock. Much of this information has been derived from the World Agroforestry Centre (see Azadirchta indica).

Neem is native to India, Pakistan, and Myanmar where it has been used by humans for more than 2,000 years. It now grows throughout the world, including in areas with dry and infertile soils.

The seeds and leaves of the tree contain the chemical compound azadirachtin which can be used to repel insects, as well as harm their digestive and reproductive properties.

Oil from neem seeds can be used as protein-rich cattle and poultry feed or made into a nitrogen-rich neem-seed cake which can be applied to soils as a fertilizer. The oil is also used in cosmetics, hair products, soaps and lotions.

The tree has also had a prominent role in traditional medicine. In East Africa, the leaves are used in a concoction to treat malaria. Neem oil has been used against skin conditions, and the bark, leaves, and fruit have been used to make a drink to treat intestinal worms.

Centre scientists say the market for neem-based pesticides is booming in India - growing by 7 to 9 per cent annually. Europe is expected to be the fastest growing market in the future.
