Palm Oil Massive Source of Carbon Dioxide

11.10.2012
Expanding production of palm oil, a common ingredient in processed foods, soaps and personal care products, is driving rainforest destruction and massive carbon dioxide emissions, according to a new study by Yale and Stanford researchers.
The study, published in the journal Nature Climate Change, shows that deforestation for the development of oil palm plantations in Indonesian Borneo is becoming a globally significant source of carbon dioxide emissions.

Plantation expansion is projected to pump more than 558 million metric tons of carbon dioxide into the atmosphere in 2020, an amount greater than all of Canada’s current fossil fuel emissions.

Indonesia is the leading producer of palm oil and palm kernel oil, which together account for more than 30 percent of the world’s vegetable oil use and can be used for biodiesel. Most of Indonesia’s oil palm plantation expansion is occurring on the island of Borneo, also known as Kalimantan, which occupies a land area nearly the size California and Florida combined. Plantation leases, covering 32 percent of Kalimantan’s lowlands outside of protected areas, represent a major land bank that is slated for development over the next decade, according to the study.

In 2010 alone, land-clearing for oil palm plantations in Kalimantan emitted more than 140 million metric tons of carbon dioxide, an amount equivalent to annual emissions from 28 million vehicles.

Home to the world’s third-largest tropical forest area, Indonesia is also one of the world’s largest emitters of greenhouse gasses, due to rapid loss of carbon-rich forests and peatlands. Since 1990, development of oil palm plantations has cleared about 16,000 square kilometers of Kalimantan’s primary and logged forested lands, an area about the size of Hawaii. This accounts for 60 percent of Kalimantan’s total forest cover loss in that time, according to the study’s authors.

“Despite contentious debate over the types and uses of lands slated for oil palm plantations, the sector has grown rapidly over the past 20 years,” said project leader Lisa Curran, a professor of ecological anthropology at Stanford and a senior fellow at the Stanford Woods Institute for the Environment. By combining field measurements with analyses of high-resolution satellite images, the study evaluated lands targeted for plantations and documented their carbon emissions when converted to oil palm.

The study’s researchers generated the first comprehensive maps of oil palm plantation expansion from 1990 to 2010. Using new classification technology developed by study co-author Gregory Asner of the Carnegie Institution’s Department of Global Ecology, the researchers quantified the types of land cleared for oil palm plantations, as well as carbon emissions and sequestration from oil palm agriculture.

“A major breakthrough occurred when we were able to discern not only forests and non-forested lands, but also logged forests, as well as mosaics of rice fields, rubber stands, fruit gardens and mature secondary forests used by smallholder farmers for their livelihoods,” said Kimberly Carlson, a Yale doctoral student and lead author of the study. “With this information, we were able to develop robust carbon bookkeeping accounts to quantify carbon emissions from oil palm development.”

The research team gathered oil palm land lease records during interviews with local and regional governmental agencies. These records identify locations that have received approval and are allocated to oil palm companies. The total allocated leases spanned about 120,000 square kilometers, an area slightly smaller than Greece. Most leases in the study occupied more than 100 square kilometers, an area slightly larger than Manhattan.

Using these leases in combination with land cover maps, the team estimated future land-clearing and carbon emissions from plantations. Eighty percent of leases remained unplanted in 2010. If all of these leases were developed, more than a third of Kalimantan’s lowlands would be planted with oil palm by 2020.

The research study, “Carbon Emissions from Forest Conversion by Kalimantan Oil Palm Plantations,” was supported by the NASA Land Cover/Land-Use Change Program, the John D. and Catherine T. MacArthur Foundation, the Santa Fe Institute and the National Science Foundation.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
