Book excerpt: This thesis seeks to understand and explain the role of fire in land cover change, vegetation and carbon dynamics in the carbon-dense, tropical peat swamp forest ecosystem of Southeast Asia. Following a methodological review, earth observation and ground data are employed to investigate fire regime, post-fire vegetation recovery, and fire-driven carbon losses in 4,500 km2 of peatland in Central Kalimantan, Indonesian Borneo. Results reveal an increasing trend in deforestation (2.2% yr-1 forest loss rate, 1973-1996; 7.5% yr-1, 1997-2005) and identify fire as the principal cause. A step change in fire regime is identified, with increasing fire frequency and reduced return interval following land drainage for the Mega Rice Project (MRP). During the post-MRP period (1997-2005), ~45% of the area was subject to multiple fires; 37% burnt twice and 8% three or more times. Extensive fires in 1997 and 2002 were associated with ENSO droughts, but fires in non-ENSO years (i.e. 2004, 2005) indicate fire incidence has decoupled from ENSO. This study provides a novel approach to quantifying relative magnitude of burn severity using characteristics of the post-fire vegetation regrowth. Combined spectral and ground data are used to demonstrate that enhanced fire frequency and burn severity limit post-fire forest recovery, with fern-dominated communities replacing tree re-growth. The character of post-fire vegetation is an important factor defining burning conditions for a subsequent fire, whilst fire frequency, severity and return interval influence both rate and nature of vegetation regrowth. Methods are proposed for deriving fire-driven carbon losses. Over the period 1973-2005, losses are estimated at 79-113 Mt of carbon (53-83 Mt from peat; 26-30 Mt from vegetation), with the greatest loss occurring during the post-MRP era (65-94 Mt). This work identifies the processes linking fire regime in tropical peatland to changes in vegetation ecology and carbon stocks and assesses the implications for ecosystem rehabilitation.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2019-12-06 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Key messagesIndonesia and Peru harbor some of the largest lowland tropical peatland areas. Indonesian peatlands are subject to much greater anthropogenic activity than Peru's resulting in high GHG and particulate emissions.We explored patterns of impact in both countries and compared predisposing factors. Impacts differ greatly among Indonesian regions and the Peruvian Amazon in the order: Sumatra > Kalimantan > Papua > Peru.All impacts, except fire, are positively related to population density.Current peatland integrity in Peru arises from a confluence of factors that has slowed development, with no absolute barriers protecting Peruvian peatlands from a similar fate to Indonesia's.If the goal is to maintain the integrity of Peruvian peatlands, government policies recognizing unique peatland functions and sensitivities will be necessary.
Download or read book Tropical Peatlands written by Jack Rieley and published by Earthscan / James & James. This book was released on 2012-01-01 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Large regions of the planet have been transformed from their natural composition into different human-made landscapes (farmlands, forest plantations, pastures, etc.). Such process, called land use change, is one of the major components of the current global change, which has brought the planet into a new geological era: the Anthropocene. Land use change is particularly important in tropical forests, as this ecosystem type is still heavily affected by deforestation for timber extraction, agricultural land creation of urban expansion. Changing land use has important implications for the services that tropical forests provide: production of goods such as timber, food or water; regulation of process such as nutrient cycling, carbon sequestration, local weather or climate extremes; generating the framework for economic and cultural activity, etc. Therefore, keeping ecosystem services when changing the use of the tropical lands is a major challenge in tropical regions. This brief book, by showcasing different research work done in tropical countries, provides a first introduction on this topic, discussing issues such as biodiversity loss, changes in local weather or nutrient cycling patterns, and economic activities around tropical forests, and tools to detect and quantify the importance of land use change.

Download or read book Vegetation Fires and Pollution in Asia written by Krishna Prasad Vadrevu and published by Springer Nature. This book was released on 2023-05-30 with total page 609 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetation fires are prevalent in several regions of the world, including South/ Southeast Asia (S/SEA). Fire occurrence and spread are influenced by fuel type, topography, climate, weather, and lightning, among others. In S/SEA, human-initiated fires are responsible for most of the incidents in addition to natural factors. Through biomass burning, vegetation fires can emit large quantities of greenhouse gases and air pollutants such as CO2, CO, NOx, CH4, non-methane hydrocarbons, and other chemical species, including aerosols that can affect air quality and health at both local and regional scales. Moreover, biomass burning pollutants can travel long distances and impact regional climate. Therefore, quantifying vegetation fires and their impacts is critical at different spatial scales. This book includes contributions from renowned researchers from the USA and South/ Southeast Asia on various fire-related topics. The contributions resulted from several international meetings and workshops organized in Asia as part of the South/ Southeast Asia Research Initiative (SARI) under the NASA Land-Cover/Land-Use Change Program. The book is divided into three sections, each containing multiple contributions: a) Mapping, Monitoring, and Modeling of Vegetation Fires, b) Greenhouse Gas Emissions and Air Pollution, and c) Air Pollution Modeling and Decision Support Systems. These sections are preceded by an introductory chapter by the editors that highlights the latest satellite-derived fire statistics and the current fire situation in S/SEA. This book will be a valuable resource for remote sensing scientists, geographers, ecologists, atmospheric, climate, environmental scientists, including policymakers, and all who wish to advance their knowledge on vegetation fires and emissions in South/Southeast Asia.

Book excerpt: Integration of peatlands into land-use monitoring systems is central to the conservation of their carbon storage – be they conserved, degraded or restored. Healthy peatlands mitigate climate change, enhance adaptive capacity and maintain ecosystem services and biodiversity. Albeit peatlands are starting to receive a high level of attention and the scientific basis for their monitoring has quickly developed over the last few years. Robust and practical approaches and tools for developing and integrating peatland-monitoring into national monitoring and reporting frameworks is an important opportunity for countries to limit global warming to 2 °C.
Download or read book Large scale plantations bioenergy developments and land use change in Indonesia written by Anne Casson and published by CIFOR. This book was released on 2014-12-29 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indonesia's forests make up one of the worlds 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 governments 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.
