The Silent Invasion: Unchecked spread of oil palm in Sri Lanka

Sri Lanka's agricultural landscape is witnessing a silent yet profound transformation with the rapid expansion of oil palm plantations. Once introduced as a commercial crop, the oil palm (Elaeis guineensis) is now at the center of a heated debate, with environmentalists and scientists warning of its devastating ecological consequences.

Speaking to The Island research scientist Rajika Gamage, said: "The spread of oil palm in Sri Lanka is not just a concern for biodiversity, but also for water resources, soil stability, and even local economies that rely on traditional crops."

A Brief History of Oil Palm Cultivation

Oil palm, originally from West and Central Africa, was first cultivated for commercial purposes in Java in 1948 by Dutch colonists. It reached Malaysia and Indonesia by 1910, where its lucrative potential drove large-scale plantations.

According to Gamage, in Sri Lanka, the first significant oil palm plantation was established in 1968 at Nakiyadeniya Estate by European planters, initially covering a mere 0.5 hectares. Today, oil palm cultivation is predominantly concentrated in Galle, Matara, and Kalutara districts, with smaller plantations in Colombo, Rathnapura, and Kegalle.

Over the decades, he says the commercial viability of oil palm has prompted its expansion, often at the cost of native forests and traditional agricultural lands. Government incentives and private investments have further accelerated the spread of plantations, despite growing concerns over their environmental and social impacts.

Economic Boon or Environmental Curse?

Supporters of oil palm industry argue that it is the most efficient crop for vegetable oil production, yielding more oil per hectare than any other alternative. Sri Lanka currently imports a significant amount of palm oil, and expanding local production is seen as a way to reduce dependence on imports and boost local industries. However, Gamage highlights the hidden costs: "Oil palm plantations deplete water sources, contribute to soil erosion, and threaten native flora and fauna. These are long-term damages that far outweigh the short-term economic benefits."
