  1. 「サトヤマ工学」をめざして

    佐藤, 寿樹; 辻, 宣行; 田中, 教幸; 大崎, 満
    里山・里海は,その地域の生業と密接な関係を保ち,自然環境・生態系の循環に即した循環型・持続型社会を構築してきた。持続的低炭素社会の構築が叫ばれているなか,里山・里海での人間と生態系の共生関係が見直されてきている。本稿では,生態系サーピスの向上と維持・六次産業化・福利厚生の充実などを要素とし、人間と自然が共生する技術とそれらを評価して最適化する技術を統合した新たな分野として「サトヤマ工学」を提案する。

  2. Detection of fire impact and vegetation recovery over tropical peat swamp forest by satellite data and ground-based NDVI instrument

    Segah, Hendrik; Tani, Hiroshi; Hirano, Takashi
    Multitemporal Principal Component Analysis (MPCA) was used for processing Landsat TM/ETM+ satellite images. MPCA was able to merge spectral data corresponding to TM-1996 (pre-fire in 1997), ETM-2000 (post-fire 1997 and pre-fire 2002) and ETM-2003 (post-fire in 2002), which was crucial for detecting the fire impact and vegetation recovery. Results indicate that the burnt areas of 1997 and 2002 were 89,086 ha (16.5%) and 31,859 ha (5.9%), respectively, within the study area of 540,000 ha. SPOT-VEGETATION 10-days Maximum Value Composite (MVC) data were also used and compared with Normalized Difference Vegetation Index (NDVI) from ground-based NDVI. Our research demonstrates the strong...

  3. 未利用材を利用した日本における木質ペレット製造のエネルギー収支分析

    土屋, 陽子; 唐沢, 邦彦; 佐藤, 寿樹; 辻, 宣行
    Domestic unused material wood possesses significant potential as an alternative feedstock to substitute fossil fuel for combustion fuel production. However, fuel conversion from the unused wood is not so advanced due to economic reasons. In this paper, energy consumption of wood pellet procurement was evaluated. The case analysis of three wood pellet factories (CERES, Inc., Hokkaido Date-shi, and Asyoro-cho) and a wood chip factory (CERES. Inc.) was carried out. The percentage of energy content of pellet procurement to output is about 20%, which is a remarkably high percentage compared with overseas pellet procurement. Energy consumption at procurement included manufacturing and...
