Deforestation Risk Assessment for Rubber Supply Chains

Updated 2026-11-02 · 4 min read · By the akar.earth specialist team

Deforestation risk in rubber supply chains: assessing Indonesian rubber catchments for EUDR, from Kalimantan forest frontiers to jungle rubber and blending.

Deforestation risk assessment for a rubber supply chain means rating each factory catchment and each supplying plot for the chance that rubber came from land cleared after 31 December 2020 or from illegal production, then verifying and mitigating before EU bales ship. In Indonesia, plot-level risk is concentrated at forest frontiers, while the biggest practical risk is that factory blending and anonymous collectors make rubber untraceable.

Rubber and forest loss

Secondary analyses link rubber expansion to substantial tropical forest loss in Southeast Asia over recent decades. Much of Indonesia’s rubber area, though, was planted long before 2020, including old jungle rubber systems that date back generations. For the EUDR, the question is not history but whether any supplying plot was forest on the cut-off date and has since been converted.

Risk by context

The Commission’s country benchmarking category for Indonesia sets the baseline due diligence level. Within Indonesia, risk varies strongly by district.

Risk factors to score

• Forest cover in 2020 and loss since. Core test, at plot level.
• Distance to remaining forest. Frontier plots can expand into forest.
• Plot type. Jungle rubber needs field verification more often.
• Tree age. Rubber planted after 2020 on land that was forest is non-compliant.
• Legal status. Forest estate and protected area overlap.
• Traceability. Share of factory intake from registered, mapped farmers.
• Yield plausibility. Rubber sold per farmer compared with tapped area.

Jungle rubber: two-way risk

Jungle rubber cuts both ways. It produces false positives, where routine management or replanting appears as deforestation. It can also hide real risk: a farmer may extend a jungle rubber garden into adjoining secondary forest, which on imagery looks like a seamless canopy. Polygons drawn with farmers, and periodic field checks, address both. See rubber geolocation and EUDR and agroforestry.

A scoring workflow

1. Catchment screen. Map each factory’s sourcing area and measure forest, recent loss and protected areas.
2. Plot screen. Check every registered plot against 2020 cover and post-2020 loss.
3. Legality overlay. Forest estate, protected areas, concession maps.
4. Traceability check. Share of intake traceable to plots, and plausibility of volumes.
5. Field verification. Visit flagged plots and a sample of clear plots.
6. Decision. Accept, exclude or mitigate, with recorded reasons.

Mitigation options

• Exclude plots cleared after 2020 and plots without legal basis.
• Process verified rubber in segregated runs. Mass balance is not accepted.
• Shift buying from anonymous collectors to registered groups.
• Monitor frontier catchments with deforestation alerts.
• Support productivity on existing plots through better planting material and tapping practices, reducing pressure to open new land.
• Support rubber agroforestry rather than conversion to monoculture.

Factory-level risk

A factory’s risk profile also depends on how it manages intake. Factories that cannot separate verified material, or that buy heavily from traders without records, cannot deliver EUDR-compliant bales whatever the plot-level picture. EU buyers will look at factory systems as much as at maps.

Carbon and conservation links

The forest and canopy data built for rubber risk assessment also supports carbon and conservation work in rubber catchments: agroforestry projects, and protection of remaining forest near frontiers. See rubber agroforestry and drivers of deforestation in Indonesia.

Signals that a catchment needs attention

Some patterns in factory and field data point to higher risk before any satellite analysis:

• Intake volumes from a district rise sharply while no new registered farmers appear.
• Collectors deliver bokar from villages close to forest frontiers or protected areas.
• Farmers report opening new gardens, or land sales near the forest edge increase.
• Deforestation alerts cluster near villages that supply the factory.
• Rubber prices rise, which historically encourages tapping of neglected plots and new planting.

These signals do not prove non-compliance. They tell the factory where to send field teams and which collectors to review first. Combining intake records with alert data is one of the most cost-effective monitoring steps a rubber factory can take.
