Research: Palm Oil Plantations Threaten Indigenous Waterways

Research: Palm Oil Plantations Threaten Indigenous Waterways | A study by the University of Massachusetts Amherst reveals that the expansion of oil palm plantations in West Papua’s Kais River watershed has significantly degraded water quality, increasing sedimentation and nutrient pollution. This environmental harm disproportionately affects downstream Indigenous communities reliant on these waters, highlighting the urgent need for sustainable land management practices and the protection of Indigenous rights.

University of Massachusetts Amherst. (2024, May 2). Oil palm plantations are driving massive downstream impact to watershed. ScienceDaily. Retrieved January 16, 2025, from https://www.sciencedaily.com/releases/2024/05/240502153115.htm

The global demand for palm oil, prevalent in products from instant noodles to cosmetics, is driving extensive tropical deforestation. Beyond biodiversity loss, new research from the University of Massachusetts Amherst uncovers significant disturbances to watersheds caused by oil palm plantations, particularly affecting Indigenous populations.

Focusing on the Kais River watershed in West Papua—a region covering over 1,000 square miles where approximately 25% has been converted into oil palm plantations—the study highlights the environmental repercussions of such land-use changes. This area is also home to various Indigenous Papuan groups who depend on the watershed for their daily water needs.

Lead author Briantama Asmara, during his graduate studies at UMass Amherst, and senior author Professor Timothy Randhir employed an enhanced Soil and Water Assessment Tool (SWAT+) to simulate the watershed’s hydrological responses under different land-use scenarios. They analyzed historical data (2010-2015), current conditions with extensive oil palm plantations (2015-2021), and projected future scenarios up to 2034, considering ongoing plantation expansion and climate change.

Findings indicate that the shift from tropical rainforest to oil palm plantations has led to increased precipitation, runoff, and soil moisture. Notably, water quality has deteriorated, with sedimentation rising by 16.9%, nitrogen levels by 78.1%, and phosphorus by 144%. Although future projections suggest a slight moderation in these effects, water quality is expected to remain significantly compromised compared to pre-plantation conditions.

Professor Randhir emphasizes the disproportionate impact on downstream Indigenous communities, stating, “They are bearing all the environmental and public health costs, while the international palm oil companies are reaping the rewards.” Asmara adds that the research aims to provide accessible data to those most affected, enabling informed decision-making.

The study advocates for regulatory measures, including limiting pesticide use during flood periods, continuous water quality monitoring, maintaining riparian buffers, and, critically, ensuring that downstream communities are informed and involved in land management decisions.

This research underscores the pressing need for sustainable land-use practices that protect both environmental integrity and Indigenous rights. As the demand for palm oil continues to rise, balancing economic interests with ecological and social responsibilities becomes increasingly vital.

Palm Oil Workers Face Hazardous Pesticide Exposure, New Report Reveals

A comprehensive study conducted by research agency Profundo, commissioned by the International Palm Oil Workers United (IPOWU) and funded by Mondiaal FNV, has uncovered alarming health risks faced by palm oil plantation workers in Colombia, Ghana, and Indonesia due to exposure to hazardous agrochemicals.

The investigation, involving 1,436 workers, identified the use of at least 56 different agricultural chemicals on plantations, including substances classified as “highly hazardous” by the World Health Organization. Notably, paraquat—a pesticide banned in the European Union since 2007—is still being exported from the EU to Indonesia, highlighting a concerning double standard in global chemical safety practices.

Key findings from the report include:

• Absence of comprehensive chemical safety policies, leading to inadequate health monitoring, safety training, and protective clothing for workers.
• None of the three countries studied have ratified key International Labour Organization conventions related to occupational health and safety.
• International palm oil buyers do not mandate specific occupational health and safety policies from their suppliers.
• Many workers are unaware of the dangers associated with pesticide exposure.
• Personal protective equipment (PPE) is often not replaced when damaged, and access to facilities for washing PPE is limited, increasing the risk of contamination.
• Workers with longer tenures reported more health issues, such as skin rashes, dizziness, and vomiting, indicating cumulative exposure effects.

The report underscores the urgent need for stronger enforcement of safety regulations, better training and equipment for workers, and greater accountability from international buyers to ensure the health and safety of those at the forefront of palm oil production.

The EU’s double standards by banning paraquat while exporting it to Indonesia

Quiroz is upset about the EU’s double standards: banning paraquat but still producing and exporting it to Indonesia. “That is unacceptable! That the EU protects its own citizens but not the rest of the world. The EU does not show much compassion for people in the supply chain. At the same time, we see that Colombia allows certain chemicals under specific and controlled conditions on palm oil and other commercial plantations, which eventually end up in the palm oil that we import. So that protection is not watertight at all.”

Risks of pesticide contamination are high for families and communities

“I did not expect that not all plantations have washing facilities for the workers’ protective clothing. So, they can’t wash their gear on-site, and they bring it home, exposing their families. There are even reports of people washing their protective clothing in nearby, flowing rivers, potentially contaminating the whole area. This happens on a small scale in Colombia and on a larger scale in Indonesia.” – lead researcher Diana Quiroz.
