Outline of Research at the Start

人口増加、経済成長、気候変動に伴って、今後も世界の水需要は増え、水逼迫も増すと考えられている。世界の水逼迫の将来予測が数多く行われてきたが、水需要を発生させる灌漑農地や、水需給を調節するダムや海水淡水化プラントなど、予測結果を左右する水利施設が、いつ、どこで、どのように増えるか見通す方法がなく、現状で固定したり、一定率で増減させたりするなど極めて簡単な仮定が置かれてきた。本課題では、生態学で発達した生物種分布推定モデルの手法を新たに導入して世界の水利施設の分布を説明する統計モデルを構築し、現在の世界の水利施設の地理的分布を理解するとともに、2050年までを予測することを目的とする。

Outline of Final Research Achievements

In the field of ecology, a statistical method known as the species distribution model has been developed to explain the distribution of habitats for specific organisms based on environmental conditions, such as climate and geography. This study applied the same model to seawater desalination plants, irrigated farmland, and irrigation dams worldwide to clarify the climatic and geographical conditions that characterize the distribution of these water infrastructures. Additionally, by incorporating future climate and population conditions into the developed model, the study conducted a future projection of the distribution of water infrastructures.

Academic Significance and Societal Importance of the Research Achievements

世界を対象にした水循環のシミュレーションの技術はここ30年程で急速に発達したが、人間の水利用に関する一般化や理論化の歩みは遅々としており、特に空間的な広がりを持った将来の水利用や水管理に関する想定ができずにいた。本研究は、種分布モデルによる水利施設の分布推定の可能性を示すとともに、将来予測にも成功した。水は生活・製造・食料生産・発電などにおいて不可欠であるが、水利用量の世界的な増加や水資源量の変動などのため、持続的な利用が危ぶまれている。本研究で得られた知見は、世界の水循環と水利用を包括的に理解するためのシミュレーション技術の確立に寄与する。
