==Introduction==

<div class="booktext">

The shea tree, also commonly known as karité (Wolof and French), Nku or Bambuk butter tree, grows wild in the equatorial belt of central Africa between Gambia and Sudan where oil palms do not grow because of insufficient precipitation.

The oil extracted has a relatively high melting point and is used in rural areas in the making of foods, soap manufacture, traditional drugs and cosmetics. Shea is mainly exported as smoked kernels and can be used as an extender in chocolate as its properties are similar to cocoa butter.

The production of shea butter is an important source of income for many women but heavy fluctuations in availability of raw materials limits profitability and restricted it as a farmed crop.

</div>

==Cultivation==

<div class="booktext">

A shea-tree (Butyrospermum Parkii) needs between 8 and 15 years until the first harvest but some time longer to reach full capacity. A tree can yield of 15 to 20 kg of fresh fruit that will produce 3 to 4 kg of dry kernels. The kernels are made up of 42 to 48% oil.

</div>

==Pests and diseases==

<div class="booktext">

Damage to foliage is caused by the larvae of Cirina butryrospermi and Anacridium moestum. Muissida nigriveriella and Ceratitis silvestrii larvae may develop inside the pulp of the mature fruit thus causing damage. The tress may suffer from leaf spot.

</div>

==Harvesting==

<div class="booktext">

Women and children collect the fallen fruit and take them back to their villages for processing into shea butter, an edible fat. Harvest is at the beginning of the rainy season. Harvest prospects are subject to considerable fluctuations.
