Nowadays each country tries to reduce CO2 emission according to the Paris Agreement. To realize global warming mitigation and low carbon society, it is a matter of great importance to promote timber utilization as a low energy consumption material and woody biomass utilization as a recyclable energy source through sustainable forest management. Under these concepts, our general research topics are geospatial analysis of forests and pursuit of sustainable forest management over multiple time and space. Specific topics are such as evaluation of forest carbon sink and its offsetting credit trading, prediction of timber supply/tree mortality, planning of forest management balancing environmental, economic and social functions of forest.

・Evaluation of forest carbon sink and its carbon offsetting credit trading according to Paris Agreement/Kyoto Mechanisms

・Prediction of woody biomass supply based on timber harvesting volume estimation

・Survival analysis of tree population in uneven-aged forest and tree mortality prediction

・Spatial analysis of forest stand based on geo-informatics
