摘要
REDD plus activities corresponded in Central Kalimantan Province, Indonesia and their GHG emission reductions potential were analyzed. Target area is located in a remote area from Pa-langkaraya, Capital of Central Kalimantan Province and consisted of immigrating people mainly from Java Island. In the target area, most of local people conducted unsustainable land use activities (e.g. slash-and-burn agriculture). From analysis of past land use in the target area, there were drastic changes in land use from 1989 after migration began. Natural secondary forest with high density was greatly reduced (2010 levels are approximately 80% of 1996 levels) and converted to cropland and settlement. Also, the reduction in natural secondary forest with high density allowed Melaleuca cajuputi Powell forest to rapidly increase in size (2010 levels are approximately 3.7 times as 1996 levels). Additionally, as marked point, there was an increase in oil palm plantations from 2008 and onwards. From results of land use change in the past, mean annual GHG emissions of 5450 Gg CO2e year-1 had been continued until year 2010. To consider counter-measure for reducing GHG emissions in the target area, the relationship between past land use changes and human activities was analyzed through workshops with stakeholders of 6 different groups (village authorities, forest fire fighting team, members of farmers group, large landowners, workers outside of village and oil palm plantation and mother having small children). The results of the workshops showed that the core problem of unsustainable land use faced by 4 of the 6 groups of stakeholders was the lack of job opportunities (means to earn a living) in the target area. Also, it was learned that core groups considered oil palm plantations is to alleviate the problem and provide a source of alternative income. Furthermore, the workshops indicated that future land use scenario (reference scenario) will be based on income from oil palm plantations and, to prevent such land conversion, counter-measures (REDD plus project scenario) of indirect activities of local people’s lifestyle improvement (e.g. A new forestry system which uses abundant resources of M. cajuputi forest) and reducing pressures on forest resources should be introduced. This study indicated, by implementing REDD plus project in the target area, potential reduction in GHG emissions is quite large and such GHG reduction will be essential as mitigation activities under the new mitigation mechanism, the Joint Crediting Mechanism (JCM) between Indonesia and Japan.
