Oil palm expansion in India should not – and need not – come at the cost of natural habitats
As someone studying how forest degradation impacts biodiversity in India, for a long time I was blissfully unconcerned that oil palm plantations would destroy the country’s natural habitats. The expansion of oil palm, while certainly concerning in the global context of forest loss and climate change, fundamentally felt like someone else’s problem (namely that of Indonesia and Malaysia).
Until suddenly, it was ours too. Almost overnight – or so it seemed to me – oil palm plantations were mushrooming all over the country. A plant I had never seen in the flesh just six or seven years ago was now seemingly popping up everywhere – southern Karnataka, interior Andhra, the foothills of the eastern Himalaya in Arunachal Pradesh. Disquieting reports emerged that entire districts in Mizoram had been designated as “oil palm districts”. My immediate reaction, all too common amongst tropical biologists, was visceral – what business does this plant have coming into India and threatening our forests?

For the sheer scale and enormity of its drastic impacts on tropical biodiversity, perhaps no plant is as widely reviled as the oil palm and no vegetable oil as villainous as palm oil. Paradoxically though, the oil palm’s notoriety is one that is at the same time both deserved and undeserved.
Palm oil – the oil extracted from the fruit of the oil palm – is an exceptionally versatile oil that finds use in a mind-boggling array of products. Not just as one of the most commonly-used cooking oils, but also in soaps and cosmetics, candles, chocolate, biscuits and ice cream. It would be safe to bet that any product with a label listing ‘vegetable oil’ amongst its ingredients has palm oil in it.
Native to west-central Africa, the astonishing yields of vegetable oil that the plant can produce have ensured its steady march in the form of forest-destroying plantations across the tropics – especially in Southeast Asia, but also increasingly in Latin America and the rest of Africa. A massive 40 to 70 per cent of the area under oil palm in Indonesia and Malaysia (about 20 million ha.) has directly replaced some of the most biodiverse primary rainforests in the world, home to critically endangered species such as the Bornean orangutan and the Sumatran tiger. Monoculture plantations of oil palm are completely devoid of biodiversity – the minuscule number of species that manage to eke out a living in oil palm plantations such as the Red-vented Bulbul and the Common Tailorbird, are those uber-generalists that can withstand the most degraded landscapes that humanity can conjure up. No wonder then that the plant has a bad rap.
But to blame the oil palm itself would be a mistake. The plant itself has no agency. It cannot transport itself across continents, cut and burn down forests and then replicate itself across millions of hectares of rank-upon-rank of evenly spaced individuals begging for water, fertilisers and pesticides. At the risk of stating the blindingly obvious, humanity has selected the oil palm for extensive cultivation because of its prodigious yields and then – dismissing biodiversity conservation and climate concerns – decided to grow oil palm at the expense of highly diverse natural habitats, mostly tropical forest. The unquestioning hatred that the oil palm often evokes is therefore perhaps a little unfair.

The oil palm is a fantastic plant. Per hectare, an oil palm plantation produces six to 10 times as much oil as the next most productive oil crops such as rapeseed, soy or sunflower. Oil palm therefore gives us the option to produce as much vegetable oil in six- to 10-fold less land area than any other oil crop. The oil palm’s stellar productivity – the very reason for its global takeover of tropical oilseed cultivation – is also a marvelous opportunity. By growing oil palm – intelligently, carefully and in the right areas – we can satisfy our demand for vegetable oil while sparing vast areas of the most biodiverse forests on the planet that might otherwise have been destroyed to grow soybean or sunflower. No other oil crop comes even close to presenting us with such a win-win option.
It is emphatically now that India, about to take the leap into extensive oil palm cultivation, must leverage the massive productivity of the oil palm plant to both attain domestic security in vegetable oil production and spare what remains of our natural habitats. India is by far the largest consumer of palm oil globally, accounting for over 20 per cent of the palm oil used worldwide. However, even as of today, India imports a colossal 99 per cent of its palm oil, largely from Indonesia and Malaysia. (In a sense, therefore, India – not producing its own palm oil – imports the oil while “exporting” the harmful environmental, socio-cultural and labour impacts of its enormous demand to south-east Asia. It is this massive shortfall in production that has prompted the government’s push for vegetable oil security under the banner of the National Mission on Edible Oil-Oil Palm (NMEO-OP).

The NMEO-OP is an ambitious undertaking that aims to place (an additional) 1.32 million ha. of land under oil palm cultivation in India by 2030. This is about three-and-a-half times the size of Goa. While the motivation behind the NMEO-OP appears clear and reasonable, there is still cause for major worry.
The NMEO-OP identifies Northeast India and the Andaman and Nicobar Islands as priority areas for oil palm cultivation. Both these regions together encompass three Global Biodiversity Hotpots, host multitudes of species that are globally threatened, range-restricted or endemic, and continue to retain the most vast forest tracts in India. These forests are not only crucial for biodiversity, but also for climate resilience, indigenous lifestyles and livelihoods. It is difficult to conceive of establishing oil palm plantations in these areas without cutting down and replacing existing forests, as has already happened in some northeastern states, primarily Mizoram. To my knowledge, oil palm plantations are currently present and being expanded in lowland areas of Arunachal Pradesh (Lower Siang, Lower Dibang districts, amongst others), Nagaland, Mizoram and parts of Assam. Of all the forested habitats in Northeast India, the low elevation dipterocarp dominated tropical rainforests are perhaps the most threatened. Large areas that historically had such habitats have now come under permanent agriculture and settlements. These are also habitats vital to endangered species such as hornbills, tigers and elephants. This is something that India simply cannot afford to do – and in fact, need not do.

First, maps of suitability for oil palm in India published by the Food and Agriculture Organisation (FAO) show that most areas of Northeast India are bio-climatically unsuitable for oil palm cultivation (except southern areas of Tripura and Mizoram). Oil palm is adapted to temperatures between 220C and 330C, and requires about 2,500 to 4,000 mm. of relatively even rainfall throughout the year. Monsoonal Northeast India, with the majority of its rainfall concentrated in about four months of the year and with temperatures dipping well below 220C, is not the natural bioclimatic envelop in which the oil palm plant thrives. Replacing forests with oil palm in Northeast India might therefore not increase domestic production in the long run, particularly if oil palm plantations in the region fail… a distinct possibility.
Second, as a recent paper ‘Oil palm cultivation can be expanded while sparing biodiversity in India’ published in Nature Food suggests, India has up to 38.8 million ha. of land, potentially available for oil palm without even touching any of its existing forests and natural habitats such as our peninsular grasslands. This 38.8 million ha. of land is the overlap between areas suitable for the cultivation of oil palm (under a scenario of climate change and the use of ideal agricultural inputs including irrigation) and existing cropland. In this massive area, the existing crops currently being grown vary from region to region, with rice in many areas and other crops such as cashew in parts of coastal Maharashtra and Goa. Replacing a fraction of the existing crops in this vast area with oil palm will go a long way in ensuring enough vegetable oil production without compromising our biodiversity or food security.

Further, while palm oil production targets aimed at enhancing domestic vegetable oil security might necessarily be a national-level priority, actually planning new oil palm plantations on the ground must be a regional exercise. In a country as geographically and culturally vast as India, the dictates of climate, availability of irrigation, transportation and milling infrastructure, land tenure systems and biodiversity considerations vary greatly from place to place. Successful oil palm plantations – and we must count the non-replacement of biodiversity-rich landscapes as an essential criterion for success – will be those that take all of these and other local-scale contingencies into account.

Finally, and perhaps most importantly, preserving our natural habitats should be absolutely non-negotiable in the current era of rapidly accelerating climate change. Monsoonal India is set to be one of worst-hit regions in the world by extreme climate-driven events such as super-strong cyclones, massive floods and severe droughts. The past year has been a grim reminder of this, and scientific consensus is that extreme weather events will become both more frequent and more intense than ever before. We will need all the forests and natural habitats we have to buffer us against such extreme events – forests to soak up extreme rainfall and prevent floods and then to release water through the year to prevent droughts.

India is in a truly unique position with respect to its oil palm cultivation. At this very early stage in our own oil palm boom, we have masses of evidence from the exceptionally well-studied Indonesian and Malaysian misadventures from which to learn. To repeat Southeast Asia’s oil palm mistakes at home would be nothing short of a tragedy. Under the aegis of the NMEO-OP, India also has the opportunity to design a transparent and evidence-based oil palm policy that ensures that natural and semi-natural habitats across the country are left completely untouched by oil palm’s ubiquitous hand. India’s oil palm plan is precariously poised. We could either end up as yet another tragedy in the long list of countries that have destroyed their last-remaining wildernesses for sterile monoculture plantations, or we could choose to be a global example of sustainable oil palm production for tropical countries across the world that will almost inevitably succumb to the charms of the oil palm.
