1.2.1: Different peat swamp forest types accross the peat dome of Sebangau National Park in Central Kalimantan, Indonesia. The differences are clearly visible in the spectral response of the Landsat imagery. Also displayed is a burned area (illustrating the necessity of historical data for peatland delineation). The red dot in the lower left figure depicts the location of the study area within Central Kalimantan.

In the past 5 years, the issue of forest and peatland fires in Indonesia has received a major concern from various parties. As one of the prevention efforts, the Government of Indonesia seeks to prevent the ignition of forest and peatland fires both anthropogenic and naturally as a result of prolonged drought. These efforts could be carried out wel...
The near-pristine bog ecosystems of Tierra del Fuego in southernmost Patagonia have so far not been studied in terms of their current carbon dioxide (CO2) sink strength. CO2 flux data from Southern Hemisphere peatlands are scarce in general. In this study, we present CO2 net ecosystem exchange (NEE) fluxes from two Fuegian bog ecosystems with contr...

... Finalizado el periodo de lluvias, el nivel de agua en la turbera disminuye sin llegar a secarse. Este proceso suele repetirse todos los años generando una lenta e incompleta descomposición de la materia orgánica y su acumulación en capas (figura 2) (Barthelmes et al., 2015). Este proceso favorece el establecimiento y reclutamiento de especies adaptadas a estas condiciones, consideradas como hiperdominantes en la Amazonia (M. ...
... Las turberas intactas proporcionan una serie de servicios ecosistémicos. Son los principales sumideros de carbono, ya que almacenan más del doble de carbono que todos los bosques del mundo en conjunto (Barthelmes et al., 2015). El secuestro y almacenamiento de carbono en turberas se basa en niveles de agua consistentemente altos, por lo que también son importantes en la reserva, purificación y regulación de los ciclos del agua, además de la regulación del clima. ...
Los palmares de Mauritia flexuosa (aguajales) son considerados las principales turberas tropicales amazónicas que contribuyen al mantenimiento de la biodiversidad y del ciclo hidrológico, además de su aporte en el secuestro y almacenamiento de carbono. Mediante una revisión bibliográfica y observaciones de campo, se identifica la importancia, factores de amenaza y oportunidad para estos ecosistemas. Las turberas almacenan más del doble de carbono que todos los bosques del mundo en conjunto y conforman un grupo objetivo para el estudio del cambio climático. El acceso a sistemas de extracción no destructiva para la cosecha de los frutos debe estar articulado con planes socioeconómicos de desarrollo. Es imprescindible la aplicación de políticas participativas de educación ambiental e incentivos económicos a las comunidades que protegen estos territorios.
... Mapping of peatlands has been addressed with many different methodologies, and detailed guidelines are available for a variety of locations (e.g. Barthelmes, Ballhorn and Couwenberg, 2015;Bourgeau-Chavez et al., 2018;Gumbricht et al., 2017) Peatlands are formed in different climatic zones, and thus hold several vegetation types and occur in different ecosystem settings. In tropical climates, for example, they might occur in mangroves and peat swamp forests, while in subtropical and warm temperate climates most have reed or sedge vegetation, and in boreal, cool temperate, subarctic and arctic regions most are dominated by mosses (Gumbricht, 2012;Prager, Barthelmes and Joosten, 2006). ...
... Based on an iterative process, peatlands are delineated by an expert incorporating all the above-mentioned input data. More details on delineation methodologies have been developed by Barthelmes, Ballhorn and Couwenberg (2015), Gumbricht et al. (2017), and Bourgeau-Chavez et al. (2018) for tropical and boreal peatlands. Other methodologies are also widely available. ...
... National academia is in a good position to promote the conservation of these important carbon pools, advocating for the inclusion of shallow peat (widely regarded as a layer less than 50 cm deep) into peatland maps. A peat layer of 15 cm thick -only half the 30 cm depth used by conservative approaches to peatland definition -already holds a larger carbon stock than a high-carbon-stock forest on mineral soil (Barthelmes, Ballhorn and Couwenberg, 2015). For historical reasons, thin peatlands are not classified as peat in many countries. ...
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. 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. This report includes 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.

The method introduced alternative approach of forest change detection in the absence of reliable data source of change at the national level using global datasets. Global Forest Watch (GFW) data was used to generate random sample points for 3 classes (forest loss, gain and no change) and assessed by the national experts. Visual assessment of the random samples using very high-resolution images available in Google earth and Being maps were employed. Using CART algorithm ( Breiman et al., 1984) and the Random Forest algorithm (Breiman, 2001) , forest change mapping was prepared in the Google Earth Engine API. The accuracy of final change product change was assessed using the methodology described in Olofsson et al., 2014. Manual cleaning was finally performed (filtering out of zones of change to match the national MMU=0.5 ha ~5 pixels and manual delineation of mis-classified zones) using the 2013 MEF land cover map to filter out loss detected to occur on the forest mask.

... 1) The utilization of the SoilGrid data, as suggested in Barthelmes et al. (2015), can help in some cases but is limited for organic soils. Its Histosol area is clearly neglecting some important peatlands, since this area is only 3.1 million km2 and even the area reported by Joosten, much likely an underestimation already, is 3.8 million km2. ...

Smoke on Water is a Rapid Response Assessment that looks at peatland location, extent, threats and the policies to manage and protect them. The goal of this rapid response assessment, carried out on behalf of UN Environment and based on the efforts of more than 30 contributors, is to raise awareness about the importance of the world's peatlands and to encourage immediate action to preserve them.
The assessment supports the Global Peatlands Initiative and is based on existing data and information. It's main messages are:
1. Peatlands are important to human societies around the world. They contribute signicantly to climate change mitigation and adaptation through carbon sequestration and storage, biodiversity conservation, water regime and quality regulation, and the provision of other ecosystem services that support livelihoods.
2. Immediate action is required to prevent further peatland degradation and the serious environmental, economic and social repercussions it entails.
3. A landscape approach is vital and good practices in peatland management and restoration must be shared and implemented across all peatland landscapes to save these threatened ecosystems and their services to people.
4. Local communities should receive support to sustainably manage their peatlands by preserving traditional non-destructive uses and introducing innovative management alternatives.
5. A comprehensive mapping of peatlands worldwide is essential to better understanding their extent and status, and to enable us to safeguard them.
