Bridgestone has launched a project in cooperation with WWF Japan to disseminate technology that improves the yield of natural rubber smallholders in the provinces of Riau and Jambi in Indonesia. By improving the livelihoods of smallholders through increased productivity, we aim to prevent deforestation caused by the development of new agricultural land, enhance the technical capabilities of smallholders supporting natural rubber production, and stabilize the supply of natural rubber. By providing instruction on correct tapping techniques and methods for collecting as cup ramp, we aim to improve yields. Additionally, we will introduce standardization of training methods and ‘farmer-to-farmer’ training.
