On October 26, 2024, JIRCAS and JICA HQ member visited an oil palm plantation that had been abandoned for conversion to a residential area near Johor Bahru, and had the opportunity to observe up-close the felling of old oil palm trees. Currently, old palm trees are not available on the general market, but by expanding the scope of social implementation using the results of this SATREPS project, it is hoped that this will lead to sustainable plantation management and economic development, and that biomass utilization will become established in society.
