美しい自然環境を空から眺めてみたいと思ったことはありませんか？リモートセンシングは，鳥になりたいという人間の希望をかなえてくれる便利なツールです。その一方で，この技術を習得するためにはそれなりの苦労が求められます。フィールドを歩き回る体力に加えて，コンピュータと統計解析への興味が必要になりますが，フィールドを歩き回って見つけた対象が空や宇宙からの情報とつながったときの喜びは格別です。一方で，植物だけに興味があって，その生態を学びたいという場合でも指導は可能です。ただし，フィールドワークはチームワークですから，原則として全員参加です。
卒論研究には，学生各自が主体的に取り組むことを望みます（基本は放牧です）。私自身が決して優秀な学生ではなかったので，成績は問いません。熱意と遊び心さえあれば，実験が成功しようと失敗しようと，そこで得た経験と仲間は一生の宝物です。大学生活の最後に，自然豊かな十勝のフィールドに触れる機会が目の前にあるのですから，ぜひ全力投球してもらいたいものです。

Grasslands are very small ecosystems in Japan, approximately 5% of the national land area, but looking at the world, they are huge ecosystems that occupy approximately 30% of the terrestrial land area. In this ecosystem, in addition to environmental problems such as desertification and land degradation, it contributes to the conservation of biodiversity and the carbon balance. In recent years, moreover, there is also growing interest in the role of multifaceted grasslands such as ecosystem services and social and cultural diversity. Furthermore, it is estimated that the world's grassland ecosystem supplies feed to an estimated 1.8 billion livestock. Therefore, sustainable improvement of productivity is also an important issue for solving food problems expected in the near future.
Conserving the existing grassland ecosystem while maintaining productivity at the same time, that is, balancing conservation and utilization has been my research target since I was a student. In order to clarify the structure and function of the grassland ecosystem, my research use remote sensing technologies such as satellite images and drones, which are good for monitoring resources and environment at large scale. In addition, GPS location information and IT device activity information are used for livestock grazing behavior and insect outbreaks that cannot be seen directly from remote sensing. My target is to analyze the temporal and spatial changes of the soil-grass-animal relationships in grassland ecosystem, and assess the effects of environmental factors. But, it's far from achieving the goal.
