Palm oil is used in a plethora of household products, from food items like packaged pastries and chips to cosmetics and soaps or even biofuels. But most palm oil is produced on mono-crop plantations, grown on huge tracts of land that were once tropical rainforests and other biodiverse ecosystems.
Mapping the links between palm oil mills, multinational corporations, and future deforestation risk is a difficult data science problem to solve, but the University of Chicago Data Science Institute and Inclusive Development International (IDI) have created a new tool to help fill gaps in understanding the problem.
The DSI and the IDI, with support from the 11th Hour Project, launched a new tool called PalmWatch on Feb. 22. Using rigorous data science and advanced, low-cost data visualization methods, PalmWatch traces palm oil supplies from the ground level, where the environmental and social impacts of palm oil cultivation occur, to the consumer brands that use the oil in their products.
“This launch of the PalmWatch tool has been a long time coming,” said David Uminsky, executive director of the Data Science Institute at the University of Chicago. “This has all the hallmarks of a great data science problem.”
“I’m very excited that this dashboard will be owned by local communities and nonprofits working in the space,” said Launa Greer, a software engineer at the DSI. “Previously, investigating the effects of palm oil supply chains was a laborious process; now groups will have analytics at their fingertips.”
Connecting data sources
In an effort to increase transparency, multinational brands do currently report the palm oil mills from which they source their material. However, creating a repository that sorts and organizes mills across the world requires collecting and standardizing this information. And even with this information, it takes additional computational methods to understand how each mill impacts local deforestation risks.
The PalmWatch project began as part of the Data Science Clinic, an experiential project-based course where students work as data scientists under the supervision of DSI staff and faculty.
To build the tool, DSI’s 11th Hour Project, led by Open Spatial Lab technical lead Dylan Halpern, first had to scrape public disclosures from thirteen multinational consumer brands that show which mills these brands source from.
This information then had to be standardized, with the palm oil mills geolocated on a searchable map. The data scientists also had to collect information about the mills, such as which companies own and operate them, which consumer brands they are affiliated with, and their RSPO certification status (a metric measuring sustainability of palm oil production).
