The impacts of climate change are changes in rainfall patterns, sea level rise and extreme weather or extreme meteorological events. This impact will further provide dangers that threaten the sustainability of human life. The main causes of climate change are deforestation and forest degradation and the growth rate of industry and transportation modes that are not environmentally friendly. Therefore, Indonesia is participating in the Paris Agreement and implementing the Reducing Emissions from Deforestation and Forest Degradation program, role of conservation, sustainable management of forest and enhancement of forest carbon stocks in developing countries (REDD+). In an effort to increase the prosperity of the State, many forests have been transferred to other uses such as the development of oil palm plantations, agricultural land and urban expansion etc. In fact, many agricultural lands have changed their function into settlements. If this happens, the forest area will continue to decrease again because after the agricultural land has turned into residential land, the forest land is converted again for agricultural expansion, this happens continuously. When viewed from the CO2 flux, there will also be changes in the basic CO2 flux from forest land, plantation land, agriculture and urban areas. The problem of deforestation and forest degradation is inseparable from the large number of forest conversion functions into oil palm plantations, expansion of agricultural areas and other uses such as urban development and infrastructure. Opportunities for climate change mitigation and adaptation include the implementation of the REDD+ program, financing of climate change mitigation and availability of climate information. The challenges faced include the lack of synergy in the policy framework and implementation of climate change control, recognition of indigenous peoples’ rights and uncertainty in the implementation of the REDD+ program.
