Survival of nearly 10,000 orangutans in Borneo oil palm estates at stake
Survival of nearly 10,000 orangutans in Borneo oil palm estates at stake | News | Eco-Business
Ever since the palm oil industry started its industrial-scale expansion in South-East Asia it has been under pressure from environmental activists and NGOs for its negative impacts.
Much of that criticism was justified because many palm oil companies were established by clear-cutting logged-over forests and replacing these with palm plantations. Biodiversity losses are massive in such conversions.
To help reduce the environmental impacts of the industry, criteria for sustainable palm oil were developed by the Roundtable on Sustainable Palm Oil (RSPO), a multi-stakeholder standard-setting platform.
Many have questioned RSPO’s ability to reduce the environmental and social impacts of oil palm development, but few quantitative studies exist to substantiate these criticisms. Here we present what we believe is the first study of RSPO’s effectiveness in reducing loss of forests and orangutan habitats on Borneo.
In a study coordinated by Borneo Futures and funded by Wilmar International, we mapped 2,717 oil palm estates and concessions on Borneo, of which 80 per cent were active in 2016 (i.e., they had planted oil palms as detected on satellite imagery).
For each area we determined: 1) whether orangutans were present; 2) what the population trend had been since 1999; 3) how much deforestation has occurred between 2000 and 2015; and 4) whether companies were RSPO-certified or not.
The total area of the mapped estates and concessions was 13.3 million ha in 2015, or about 17.1 per cent of the land area of Borneo.
About 34.1 per cent of the total mapped plantation area was planted with oil palm, 21.2 per cent ha still forested, and the remainder used for other purposes (small-holder agriculture, mining etc.).

The absolute loss of orangutans is significantly lower in RSPO concessions on Borneo than in non-RSPO certified estate and concessions, but that relative loss rates are about the same.
Total loss of intact and logged forest between 2000 and 2015 in RSPO-certified management units (815,592 ha) was 73,559 ha (i.e., 9.0 per cent of total estates and concessions area). Of this, 49,030 ha were lost after November 2005 (the RSPO deforestation cut-off date), or about 0.6 perc ent of the total RSPO-certified area per year.
There is a declining trend in annual forest loss from RSPO-certified management units after November 2005 from 13,417 ha per year between November 2005 and November 2007 to 1,839 ha per year for the same total area after May 2014.
Total loss of intact and logged forest between 2000 and 2015 in areas allocated for oil palm that were active and non-RSPO certified in 2016 was 1,748,123 ha of forest loss, or about 25 times more than from RSPO forests. Of this, 1,453,928 ha were lost after November 2005, i.e., 1.5 percent of the total area per year.
In 2014, an estimated 275 orangutans occurred in 32 RSPO-certified management units, and an estimated 9,300 orangutans in 529 non-RSPO areas.
Between 1999 and 2014, orangutan populations in areas that are now RSPO-certified declined from 419 to 275. In the same period, orangutan populations in non-certified units declined from 13,480 to 9,302.
This suggests that the absolute loss of orangutans is significantly lower in RSPO concessions on Borneo than in non-RSPO certified estate and concessions, but that relative loss rates are about the same.

With 10,000 orangutans currently occurring in areas allocated to oil palm the potential for disastrous outcomes for these animals is significant. Business-as-usual practices will lead to deforestation and the likely death of these protected animals.
Rescuing all of these 10,000 animals is not only logistically impossible, it would also incur costs of some USD 100–200 million to the conservation community. As shown in a recent study, such funds are much better spent on protecting remaining habitats. Orangutan rescues in oil palm areas should be a very last resort.
We can only prevent the deaths of these 10,000 orangutans if: 1. Government makes it very clear that the destruction of habitats of protect species and the killing of these animals is illegal and will be punished; 2. The 561 oil palm companies that currently have orangutans on their land are held responsible for protecting and effectively managing remaining orangutan habitats; 3. NGOs and other groups work with these companies to facilitate implementation of effective conservation practices.
We conclude that there is room for further improvement on environmental practices in RSPO-certified estates and concessions, but that orangutans have better prospects in management units owned by RSPO members, because of more effectively avoided forest losses there. RSPO compliance as measured through forest loss is improving with time.
