The document discusses a case study of rubber plantation rejuvenation efforts in Jambi Province, Indonesia. It notes that the province has large areas of forest plantations that are an important source of rubber and other commodities. However, increasing population growth has led to the conversion of plantation land to residential areas. To maintain rubber production and smallholder livelihoods, the Jambi government implemented a participatory rejuvenation program from 2006-2010 to replant aging rubber trees. This approach involved local governments and emphasized farmer participation, but initial results showed only 10% of targeted land was rejuvenated in three years, indicating the need for improved planning and coordination between stakeholders.
