- A scientific research-backed study on oil palm cultivation in the aftermath of the recent ban in Sri Lanka
Oil palm is considered to be one of the most competitive vegetable oil crops in terms of productivity. The crop provides five times as much vegetable oil per hectare compared to alternative crops, such as coconut, and sequesters more carbon per hectare than tea and coconut.
According to studies conducted by Sri Lankan scientists, per litre of oil palm requires lesser fertilisers and less water than coconut, dry rubber or tea. The crop primarily uses rainwater for cultivation, and there is no evidence of palm oil plantations causing groundwater depletion. Yet, despite a wide range of virtues, the Sri Lankan government has decided to ban palm oil production, ordering replacement of oil palm trees with rubber plantations, on grounds of unfavourable environmental and social impacts.
Myths and truths
Unfortunately, palm oil has been at the receiving end of a perception that is nurtured based on unfavourable emotions and not facts around it. Claims of oil palm plantations leading to widespread deforestation and damage to ecosystems have hardly any transparent scientific research backing them. In Sri Lanka, palm oil does not replace forest but other plantation crops, primarily rubber or coconut. Therefore, its biodiversity performance needs to be compared with these crops, and as found in various studies, the differences in biodiversity between oil palm, rubber, tea and coconut plantations are neither significant nor conclusive.
In an attempt to break the myths around palm oil and its production, Solidaridad has released the “Myths and Truths of Oil Palm”, a research-based scientific study that provides information and assessments on palm oil through an in-depth literature review on research findings by over 15 leading scientists from top universities and research institutions across Indonesia, Malaysia, India and Sri Lanka. A result of extensive research, the publication vividly portrays the social, economic and environmental impacts of oil palm production.
Research highlights
- Sri Lanka annually imports 180,000 to 220,000 MT of vegetable oil. This can be met with 50,000 ha of oil palm or 271,000 ha of coconut. Oil palm yields 4 to 5 times oil per ha
- Oil palm plantations have served Sri Lanka for over 54 years, starting around 1968
- Palm oil is in many aspects healthier than coconut oil
- Currently, profits generated per ha/ year; oil palm Rs. 900,000, coconut Rs. 280,000, rubber Rs. 70,000, tea Rs. 45,000
- The daily wages per month for workers; oil palm worker Rs. 30,000-50,000, tea estate worker Rs. 25,000, rubber tapper Rs. 18,000
- No evidence has been found of soil and water resource degradation in the oil palm growing estates in Sri Lanka
- A worldwide study which included Sri Lanka has shown that in Sri Lanka, the water footprint of coconut oil is 10,548 m3water/ton, palm oil 3,946 m3 water/ton
