A core part of the Partnerships for Forests (P4F) strategy is to support and strengthen the implementation of corporate supply chain commitments, existing public procurement policies and developing new responsible sourcing guidelines and implementation tools. P4F has supported GPSNR for more than three years, in enhancing their strong focus on smallholder participation in decision-making and representation. This work, which has contributed to bringing smallholder farmers directly into the platform, demonstrates the importance of setting up long-term structures for producers and upstream stakeholders in the natural rubber industry.
