Outline of Final Research Achievements

We conducted micrometeorological observation of greenhouse gases (GHGs; carbon dioxide and methane) in a tropical peat swamp forest in Central Kalimantan, Indonesia. We obtained those gas flux data in both dry and wet years. This improved our understandings of the effects climate and environmental factors on these GHGs. We also conducted the incubation experiment of acidic peat (from peat swamp forest) by neutralizing pH and measured CH4 production in anoxic condition. Such kind of neutralization is normally conducted during land conversion.

Academic Significance and Societal Importance of the Research Achievements

天然林の伐採・排水・火災・プランテーション化といった熱帯泥炭湿地林の急速な開発は、二酸化炭素放出などを通じて地球の森林や大気環境に多大な影響を及ぼす。本研究では、面積的に規模の大きい東南アジア熱帯泥炭に着目し、温室効果ガス動態の解明を目指して研究を進めた。得られた結果から、土地利用改変が湿地地下水の溶存炭素の質や量を改変すること、プランテーションでの中和化がメタン発生量を増大させるという知見が得られ、温暖化対策に取組む現地や国際社会に対する情報提供の点から社会的意義が高い。火災などを通じて放出される各種物質の動態などについても新たな知見が得られ、著名国際誌に多数発表しており学術的意義も高い。
