More than 80 per cent of the Indonesian rainforest, mangroves and peatlands most vulnerable to being cleared for palm oil production is completely unprotected by the country鈥檚 Forest Moratorium, according to new research.
In a study published in the journal , a team of experts at the University of 91直播鈥檚 Institute for Sustainable Food, Grantham Centre for Sustainable Futures and the National University of Singapore developed a model to explain and predict the expansion of oil palm plantations.
By considering the potential profitability of converting natural habitats into plantations, the researchers were able to predict oil palm expansion with 85 per cent accuracy and determine the importance of economic forces as a driving factor. They also found a 鈥榗ontagion鈥 effect, whereby areas with existing plantations experience greater crop expansion, potentially facilitated by an existing workforce and infrastructure.
The UK government this week proposed a ban on larger businesses using products grown on land that was deforested illegally 鈥 but this research highlights the limitations of a key conservation law in Indonesia, the world鈥檚 largest producer and exporter of palm oil.
Indonesia saw a huge increase in oil palm plantations from two mega hectares (Mha) in 2000 to 8.6Mha in 2015, with the loss of 6Mha of forest. In 2010, the country passed legislation protecting over 69Mha of forest and peatlands from conversion under a Forest Moratorium, while allowing oil palm expansion in forests already licensed or degraded by logging.
91直播 and National University of Singapore researchers found that just 10 per cent of the areas identified as vulnerable to oil palm expansion by 2025 are currently protected by Indonesia's Forest Moratorium, while 83 per cent of vulnerable natural areas are left unprotected by the law.
鈥淎s global palm oil demands continue to rise, our model allows us to predict future crop expansion and identify areas most at risk from deforestation.
鈥淚ndonesia鈥檚 Forest Moratorium was introduced to protect precious habitats 鈥 but its failure to cover most areas vulnerable to oil palm expansion means it actually risks exacerbating the climate and biodiversity crises.
鈥淚t鈥檚 good to see the UK government trying to end the use of products grown on illegally deforested land, but without adequate protection forests remain vulnerable to excessive crop expansion and habitat destruction.鈥
