Palm oil: The Good, the Bad and a History

Elaeis guineensis is a single-stemmed palm tree in the Arecaceae family that can reach up to 20 metres in height. It is native to West and Southwest Africa and thrives on open, flat land with plenty of water. The palm’s plum-sized palm fruit grow in bunches of around 1,000 and are reddish in colour. The fruit is a drupe, which means it has a fleshy outer layer surrounding a single seed. Both the flesh and seed are rich in oil, which can be extracted. Elaeis guineensis is the primary source of palm oil and is closely related to the American species Elaeis oleifera.

History

In the late 1800s, archaeologists showed that humans have used Elaeis guineensis for the past 5,000 years. They found the plant in a tomb dating from 3,000 BCE in the ancient Egyptian city of Abydos. It is widely believed that traders brought the palm to Egypt from elsewhere in Africa.

Europeans were introduced the palm sometime during the 16^th-17^th centuries. They originally traded for palm oil in the ‘palm oil coast’ (the southern coast of Nigeria) before growing the plant in their colonies. One such colony was the British-occupied Malaysia. Elaeis guineensis became established in Malaysian plantations in the early 1900s. For the most part, these plantations were owned and run by the British until the late 1900s when the Malaysian government took control.

The government set up the Federal Land Development Authority (Felda) in 1956 to operate their plantations. The main aim of Felda was to use the plantations as a means of eradicating poverty in the area. Those wishing to be involved were given 10 acres of land in which to plant oil palms or rubber plants and 20 years in which to pay off the debt for the land. In the 1960-70s, the Malaysian government expanded the project to include other crops so that they had an economic ‘cushion’ for when the price of rubber fell. Soon the land dedicated to rubber became more palm oil plantations. By the end of the 20^th century, Felda had given rise to other organisations, such as the Federal Land Consolidation and Rehabilitation Authority (FELCRA) and the Sarawak Land Consolidation and Rehabilitation Authority (SALCRA). These additional organisations had the same primary aim as Felda; to eliminate poverty through the cultivation of crops. Today Felda is the world’s largest palm oil producer, with around 900,000 hectares dedicated to growing the palm.

Uses

Palm oil can be extracted either from the flesh of the fruit or from the seed. As mentioned previously, some of the earliest findings of Elaeis guineensis were in Egyptian tombs. The vast quantities of oil found have suggested that they used it for culinary rather than cosmetic purposes. The unrefined oil is still a common cooking ingredient in West Africa today, but elsewhere is always refined before use. Palm oil is high in saturated fats, making it solid at room temperature and able to withstand higher temperatures compared to many other cooking oils. For these reasons, as well as a rise in popularity for naturally saturated fats, palm oil has become a cheap and popular substitute for butter. Due to its ability to withstand high temperatures, palm oil is second only to the soybean in its use as vegetable cooking oil. Oil from Elaeis guineensis is often also included in many other foods, such as ice cream, crisps and chocolate.

Although around 90% of palm oil is used in food, its use is not limited to culinary purposes. It is also added to cosmetics, shampoos and soaps. In recent years, palm oil has become a popular biofuel. Traditional African medicine have used Elaeis guineensis as a laxative, to stimulate the production of urine, as a poison antidote, to cure gonorrhoea and to treat skin infection – to name but a few uses. However, it may not be entirely harmless as some studies have linked palm oil with cardiovascular diseases.

Social and environmental concerns

Despite its wide range of uses, there are many social and environmental impacts of cultivating the palm. Growing the plant is a source of income for governments – particularly in Malaysia – as well as a major provider of employment. However, there have been many unfavourable social effects of this. Many palm oil plantations have appropriated lands for cultivation without consulting or compensating the local residents. In some cases, the plantations do not even employ the locals but rather import labour or illegal immigrants.

Along with the social concerns that accompany the plantations, there are also substantial environmental impacts. Cultivation of the plants has caused irreversible damage, including deforestation, habitat loss and increased greenhouse gas emissions. Large areas of tropical rainforests have been cleared for plantations and the resulting biodiversity loss could result in the extinction of species of potential medicinal importance. In some areas where enforcement of environmental legislations is lax, plantations have had little regulation to stop tem encroaching into protected areas and releasing pollutants into the environment.

Other states have implemented environmentally-friendly practices to try to limit the damage. These have included the use of waste products as sources of ‘renewable’ methane production to generate electricity. However, palm oil plantations are still environmentally damaging as many rainforest are above peat bog that store vast amounts of carbon. The deforestation and bog draining involved in setting up the plantations releases this carbon into the atmosphere, contributing to greenhouse gas emissions and global warming. Many environmental groups have pointed out that the environmental impacts of running plantations are far more damaging to the climate than the benefits gained by the biofuel produced.
