Indonesia’'s forests make up one of the world’s most biologically diverse ecosystems. They have long been harvested by local people to meet their daily needs. Since the 1970s, a combination of demographic, economic and policy factors has driven forest exploitation at the industrial scale and resulted in growing deforestation. Key factors behind the forest loss and land use change in present-day Indonesia are the expansion of oil palm, plywood production and pulp and paper industries. Oil palm has been one of the fastest-growing sectors of the Indonesian economy, increasing from less than 1 million hectares in 1991 to 8.9 million hectares in 2011. The plywood and pulp and paper industries have also expanded significantly since the log export ban in 1985. All three sectors have contributed to deforestation. Several measures are being taken to reduce the loss of tropical forests in Indonesia. These measures are driven by growing global concern about the impact of deforestation on biodiversity and global warming and the Indonesian government’s commitment to reduce greenhouse gas emissions. A major policy initiative revolves around developing renewable energy from biomass that can be sourced from oil palm, sugar, cassava, jatropha and timber plantations. This paper analyzes these measures and assesses the conditions under which they may be most effective.

This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.
