Triharmony/Trilemma of Nutrients Assets in tropical peatland

Written by

Osaki and colleagues have developed an innovative nutrient management system for tropical peatland in high groundwater levels, known as AeroHydro culture.

Peatland soils and water are characterised by low nutrient concentrations. Despite this, biomass in native tropical peatlands is abundant and has adequate nutrients. At Hokkaido University, Sumitomo Forestry Co Ltd, Japan, and BRIN, Indonesia, scientists studying nutrient cycling in peatlands have developed an innovative nutrients management system for agriculture. Their approach – AeroHydro culture – involves cultivation using high groundwater […]

Triharmony/Trilemma of Carbon Assets in tropical peatland

Written by

The water status of tropical peatlands regulates carbon emissions. From this, Osaki and colleagues are developing the Water–Carbon Interaction Model from which they estimate carbon flux related to human activity and climate change.

Tropical peatlands provide globally important reservoirs of water and carbon, and the cycles of these two elements are intricately connected. At Hokkaido University, Sumitomo Forestry Co, Ltd, Japan, and BRIN, Indonesia, scientists have developed a model for mapping carbon emissions from tropical peatlands. Their integrated monitoring, reporting, and verifying (iMRV) system measures dynamic changes in water and carbon cycles, biomass […]

The ultimate veg patch: Can phytotechnology save cultivated peatlands?

Written by

Intact, water-logged peatlands are a stable store of the world’s carbon, but if drained they can become near perfect (organic) soils for growing high-cost vegetables. It was thought that you couldn’t cultivate a peatland without ruining it and releasing its carbon into the atmosphere. Dr Jacynthe Dessureault-Rompré, with her team at Laval University in Québec, Canada, has been investigating whether […]

Peatlands’ past suggests fast-changing future

Written by

In this article Prof Booth and Hotchkiss’ research uses the paleoecological record preserved in kettle hole ecosystems of northern Wisconsin to assess the potential for climate-induced ecosystem state shifts, as well as the ecological effects of these events.

Minimising and mitigating the effects of global climate change rely on accurate predictions of future climate, vegetation changes, and feedbacks between the Earth and its atmosphere. Prof Sara Hotchkiss, of the University of Wisconsin – Madison, and Prof Robert Booth, of Lehigh University, Pennsylvania, have investigated the effects of climate change on an overlooked landscape, the kettle hole ecosystems of […]
