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 […]

Transdisciplinary field science based on Land-Surface Management (LSM)

Written by

Through transdisciplinary field science, and land-surface management, saki, Kawakiat, Kato, Tsuji, and Sisva are developing methods to restore terrestrial land systems, applying three key technologies such as AeroHydro culture in peat/wetland, Z-tillage culture in arable land, and HydroCycle culture in dry/semi-arid land

Land-Surface Management (LSM) technology, which is based on transdisciplinary field science, offers a solution for ‘Earth Regeneration’. The general principle behind LSM technology aims to control and manage three basic elements of our land surface – water, oxygen, and nutrients – even in different eco-types such wetland or dryland. On a global scale, there are large areas of inferior soil […]

Nature as an asset: Natural capital in ‘FutureCity’ Shimokawa

Written by

Professor Mitsuru Osaki and Mr Takashi Kasuga have developed a way to quantify natural capital, measuring the town of Shimokawa in Japan.

Natural capital provides the goods and services that sustain humankind, but accurately quantifying it remains problematic. Professor Mitsuru Osaki (Hokkaido University) and Mr Takashi Kasuga (NPO FutureForest Institute) have addressed this issue by focusing on Shimokawa, a town in northern Hokkaido, Japan. Shimokawa aims to achieve economic stability by using its forest resources. Quantifying 19 variables related to agriculture and […]
