Outline of Research at the Start

本研究では,都市化や温暖化によってもたらされる都市住民と生物の接触が引き起こす様々なリスク(以下,生物リスクと略す)の適切な管理政策を検討するために,経済学と生態学の融合を行う.都市において生物リスクをもたらす生物種は,都市内に限れば害獣であるものの生態系の中では重要な働きを持つ.この生物リスクは,住民と生物の空間的相互作用とみなせる.そこで,本研究は,人類と生物の接触がもたらすリスクの管理政策を接触の空間相互依存作用を明示のうえ検討することを目的として都市経済学と生態学の統合モデルの構築を行う.

Outline of Annual Research Achievements

Yoshida & Kono (2020)が用いたLotka-Volterra モデルをメタ個体群モデルに置き換えた.置き換えにあたってはメタ個体群モデルの理論モデル構築を行っている瀬野先生の教科書および論文を参照している.メタ個体群モデルでは,局所的集団(パッチと呼ばれる)が多数点在し,パッチ間を生物が移動しており,マクロの生態系はパッチを総和したものになる.その構築したメタ個体群バージョンの生態系モデルと都市経済モデルの統合モデルの定常解について理論・数値分析を行っている.ここでいう定常はマクロでの意味である.具体的な政策分析として都市公園と森林の位置関係の分析を行っている.その結果を一橋大学や土木計画学において発表している段階である.発表時にいただくコメントをもとに修正を行っている段階である.現時点では,理論的性質の解析にとどまっているため,今後,パラメータをできるだけ現実のデータをもとにキャリブレーションして現実味のあるシミュレーション分析に近づける予定である.現在,以上の研究を相澤,吉田,占部,河野で行っている.十分なデータがなければ,感度分析的に複数パラメータを用いることで一定の結論を導ける.なお,森林の植生分布やその変化の設定も必要である.この設定は農学にも詳しい井元が行う.
クマの都市内での出現が問題になっているため,札幌市南区を中心としたアンケート調査を調査会社とともに行った.アンケート調査内容は,クマに関する被害歴,クマによる生活への影響,様々な生活リスクとクマリスクとの比較等を調査している.回答数としては,およそ1,200得た.クマに対しての恐怖感の程度がコロナと同程度などの把握ができている.現在,クマの恐怖感の程度や生態としての価値について詳細な分析を行なっている段階である.まとまったところで学会発表を行う予定である.この解析を現在,井元,吉田,河野で行っている.

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

論文発表もすでにあり,計画通り進んでいる.

Strategy for Future Research Activity

具体的な政策として公園の位置を対象に分析を開始した.公園をベースに都市で繁殖する動物について性質の調査を今後行う.近年では,アライグマなどの外来種も繁殖して問題になっている.これらの調査とともに,社会的に大きな問題になっているクマの研究についても進める.以上について,学会等で発表しながら成熟度を上げていく予定である.
