Forests in the world have been decreasing rapidly, followed by serious global warming from greenhouse effect gas (GHG) and impacts on livelihoods of forest-dependent people. In Japan, abandoned forests should be adequately managed and sustained rural villages in the aging population. Our researches investigate sound relationships between global policy issues as climate change/forest conservation and improvement of local livelihoods in tropical countries as Southeast Asia, and development of rural livelihoods ithrough effective use of wood production and biomass resources in Japan.

The followings are research topics:

  1. Relationships between forests and people in tropical forests, Southeast and South Asian Countries
    -Collaborative forest management in protected areas, especially National Park with governments and local people
    -Certification schemes including forest certification, fair-trade coffee, oil palm plantation (RSPO)
    -Participatory forest management
  2. Relationships between forests and people in forests, Japan
    -Working safety and technical training in forest operations
    -Artificial forest management with conserving biodiversity
    -Ergonomic research for sutainable forest managemnt

The main goal of research in this laboratory is to understand the water, energy, CO2, and other mass cycles, and the relationships between these cycles and the biome. The main subjects of our research and education are forest/mountain hydrology, forest/mountain meteorology, and soil erosion control engineering. Our research is divided into five areas:

  1. Water, energy, and CO2 exchanges between the atmosphere and the biome in multi-scale
    The results of this research will contribute not only to the understanding of water, energy, and CO2 exchange processes in spatial scales of from a leaf, canopy to region, and the effects of physiology on these cycles, but also to the prediction of global changes.
  2. Evaluation of water cycles on a watershed scale
    The water cycle system is investigated using several experimental watersheds. The results will contribute to both the physical understanding of run-off systems and the prediction of landslides and debris flow.
  3. Hydrometeorological characteristics of sub-alpine mountains
    The hydrometeorological conditions of sub-alpine mountains are quite different from those in hilly mountains. Our main goals are to estimate the spatial and temporal distributions of meteorological elements throughout the year, and to understand snow accumulation and ablation processes in high mountain areas by using a new model and remote-sensing data.
  4. Hydrometeorological characteristics of urban environment
    In urban or suburban areas where human activities change land surface conditions variously, hydrometeorological effects of complex land use including urban vegetation are investigated.
  5. Sediment yield in a mountain watershed
    The characteristics of sediment yield from a watershed, and watershed conditions such as vegetation, topography, and geology, are investigated. Our results will contribute to watershed management and river planning.
