Tropical Peatland Ecosystems

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.

In this "Tropical Peatland Eco-management" book, eco-management is new terminology as an abbreviation of "ecology-based management for natural capital enhancement". Key concept on this eco-management is derived from previous book: "Tropical Peatland Ecosystem"(Springer, 2015, eds. by M. Osaki and N. Tsuji). Based on this new concept, this book thoroughly examines tropical peatland eco-management for scientists, political decision makers, governmental officials, land managers, students, and NGO/NPOs who are interested in 1) what the impact of peatland on climate change and ecosystem function, 2) how the management of disturbed peatland, and 3) drawing global scale restoration mechanisms of peatland and wetland. In tropical peatland, a large amount of GHGs (carbon dioxide, methane, and nitrous oxide) is emitted due to the unappropriate development and inadequate management of peatland. The peatland ecosystems consist of the carbon–water complex, which is affected easily by the impact of human and climate change. Throughout much research of tropical peatland, the problems that result from development of tropical peatland are found to stem mainly from a lack of understanding of the complexities of this ecosystem and the fragility of the relationship between peat and forest and also between carbon and water. In past, almost all peatland development and management system have been generally designed on “water drainage system”. On the contrast of old system, an innovated eco- management is, here, proposed as “water irrigation system”, including water cycling and natural capital enhancement. Through this book readers will learn the advanced peatland eco-management, with more practical methods and procedure based on ecosystem knowledge.

Tropical peatlands are found mostly in South East Asia, but also in Africa and in Central and South America. They and peat-swamp forests store large amounts of carbon and their destruction, particularly through the development of plantations for oil palm and other forms of agriculture, releases large quantities of greenhouse gases which contribute to climate change. They are also complex and vulnerable ecosystems, home to great biodiversity and a number of endangered species such as the orang utan.The aim of this book is to introduce this little known but important and vulnerable ecosystem in a way that explains its long standing interaction with the global carbon cycle and how it is being destroyed by deforestation and inappropriate development. The authors describe the origin and formation of peat in the tropics, its current location, extent and amount of carbon stored in it, its biodiversity and natural resource functions and key ecological functions and processes. Appropriate hydrology is the key to the development and maintenance of peatlands and the unique aspects of tropical peatland water supply and management are also explored. In the same vein the nutrient dynamics and budgets of this ecosystem are explained in order to show how complex habitats can be maintained mainly by rainwater containing very low concentrations of essential chemical elements. Past and present impacts on tropical peatlands in SE Asia are discussed and the need for restoration and wise use highlighted. Finally, projections are made about the future of this ecosystem as a result of continuing human impacts and climate change.

This book focuses on eco-evaluation system monitoring and sensing, carbon-water modeling, mapping, and disaster prediction. It is the 3rd book on tropical peatland issues, following 1st "Tropical Peatland Ecosystem" and 2nd "Tropical Peatland Eco-management" publications. Tropical peatland is also a wetland, mangrove, and rainforest. With this nature, two major key elements of tropical peatland are water and forest. This book introduces the relationship and interaction among water, oxygen, and nutrients as well as aspects of the forest as the driving force of carbon stock and the carbon cycle. Eco-evaluation system is key to conserving, managing, and restoring tropical peatlands, however comprehensive system for Eco-evaluation in the Tropics is not yet established. This book reviews and proposes Eco-evaluation methods in the Tropics Ecosystem, focusing mainly on the peatland ecosystem and others, covering Social Capital such as Credit, Bonds, National Accounting, etc.

An interdisciplinary book tackling the challenges of managing peatlands and their ecosystem services in the face of climate change.

The tropics are home to most of the world’s biodiversity and are currently the frontier for human settlement. Tropical ecosystems are being converted to agricultural and other land uses at unprecedented rates. Land conversion and maintenance almost always rely on fire and, because of this, fire is now more prevalent in the tropics than anywhere else on Earth. Despite pervasive fire, human settlement and threatened biodiversity, there is little comprehensive information available on fire and its effects in tropical ecosystems. Tropical deforestation, especially in rainforests, has been widely documented for many years. Forests are cut down and allowed to dry before being burned to remove biomass and release nutrients to grow crops. However, fires do not always stop at the borders of cleared forests. Tremendously damaging fires are increasingly spreading into forests that were never evolutionarily prepared for wild fires. The largest fires on the planet in recent decades have occurred in tropical forests and burned millions of hectares in several countries. The numerous ecosystems of the tropics have differing levels of fire resistance, resilience or dependence. At present, there is little appreciation of the seriousness of the wild fire situation in tropical rainforests but there is even less understanding of the role that fire plays in the ecology of many fire adapted tropical ecosystems, such as savannas, grasslands and other forest types.

This is the first truly ecosystem-oriented book on peatlands. It adopts an ecosystems approach to understanding the world's boreal peatlands. The focus is on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and it provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia.
