和歌山県有田市の果樹園における観測に加えて，大阪府立大学の敷地内のミカン樹における画像観測を実施した．有田市果樹園においては，土壌水分量，葉面温度，気象要素の経時観測に加えて，定期的なドローン撮影（熱赤外線カメラ，マルチスペクトルカメラ）と葉の水ポテンシャル，気孔コンダクタンスの計測を行った．大阪府立大学のミカン樹においては，定期的におよそ2時間間隔での葉の水ポテンシャルを観測し，そのときのRGB撮影と近赤外マルチスペクトル撮影を行い，色彩情報との関係性を検討するとともに，葉先の位置の変位を計測し，変位量との関係性の有無を調べた．その結果，葉面温度と気温の差が葉の水ポテンシャルの推定に利用できる可能性を示すことができ，葉面温度から気孔コンダクタンスを推定するモデル式を提示した．気孔コンダクタンスの観測値と計算値はおよそ適合することを示した．また，ミカン果実品質への影響度が高い9月において，RGBと葉の水ポテンシャルの相関が高いこと，葉の水ポテンシャルは葉の変位量とも関係性が見られることを明らかにした．以上より，遠隔情報を用いて葉の水ポテンシャルが推定可能であることが示唆された．水分動態解析に必要となる蒸発散量については，土壌水分量の観測値から推定し，これが葉面温度の変化の特徴と弱い関係があることを示した．
また，昨年度に開発した，ラズベリーパイと無線LANを利用したマルチスペクトル撮影および土壌水分の多点計測を自動で行えるシステムを有田市果樹園に導入し観測を開始することができた．さらに，浸潤計を用いて土壌の浸透特性を評価することができることを確認した． -

令和3年度には、前年度に引き続き湖内熱収支の検討を進め、比較的高い精度で得ることができた現地測定データを用いて潜熱量の推定法を検討した。特に、大気安定度を考慮したバルク係数モデルを用いて潜熱量の推定値を渦相関法による測定値と比較・検討した。加えて、氾濫水の地下水涵養の有無についての検討、領域気候モデル（WRF）とDWCM-AgWUモデルとのカップリングに関する基本アルゴリズムの決定ならびに組込み方法について検討した。そこでは、カンボジアへの渡航が困難であったことから、代替で日本の湖干拓により、湖面積が1/5になった八郎湖流域を取りあげで同組み込み方法の検討を行った。
また、環境指標としての安定同位体の利用方法を明らかにした上で、トンレサップ湖や湖周辺地域での降水、湖水、河川水の定期的なサンプリングを共同研究先の水資源気象省と協力して継続して行った。ただし、同位体分析を着実かつ本格的に進めたが、コロナ禍により、共同研究者による日本へのサンプリングデータの送付が滞り、一方で日本側研究者の渡カンボジアを全く果たせなかったことから、現地訪問時の定点サンプリングもできなかった。そのため、分布型水循環モデルによる計算シミュレーションと環境指標からのアプローチを統合したネオ診断法の展開に遅れが生じた。他方、観測塔での観測は継続するとともに、気候変動実験における各種GCMの結果も入手し、独自のバイアス補正法により1～5kmのダウンスケールデータの作成を開始した。ただし、観測塔上のバッテリー等は交換補修が必要となっているが、現地訪問ができず太陽パネルが利用できない夜間の観測に支障をきたす事態の改善はできなかった。 -

Soil is the largest terrestrial carbon sotrage and a valuable medium for plant growth, thus conservation of organic soil is essential for ecosystem stability. We found that the physical aspects of pore structure and downward infiltration are strongly related to soil organic matter, and we clarified the mechanisms of soil organic matter accumulation and loss on a watershed scale. Downward infiltration increases soil organic matter, but soil runoff, the major cause of soil degradation, has a canceling effect on it. In addition to CEC and silt content, permeability factors also play a role in the conservation of soil organic matter at the continental level, indicating the importance of physical aspects in a wide area.

The Cordillera rice terraces in the northern part of the Philippines, known as a World Heritage, conveys the traditional culture of the region and exists as a production base for rice cropping and a part of natural water and material cycles. However, the collapse of rice terraces has become more serious, and proper and efficient farm management has been required to maintain the rice terraces.We focused on the structure of the rice terraces and the circulation of water and materials, and found that hard pan, which was formed in the lower layers of the paddy fields to store water, decided the stability of the rice terraces.There were some rice terraces with excess organic matter and the paddy can pond the water by small particle clogging without forming hard pan.If that was the case, mineral leaching occurred and stability of the paddy becomes lower.
We can conclude that hard pan is invisible, but its formation is crucial for stable rice paddy management. -

In this project, a distributed hydrological model and a crop growth model were dynamically coupled with improvements especially made on the land-surface process sub-model. The improved model was applied on a basin scale, and the impact assessment of climate change on agricultural water resources and rice production was conducted to derive the basin-scale future projection and its uncertainties (“quantitative assessment of scientific knowledge on climate change”). In addition, farmers’ empirical knowledge on agricultural management against year-to-year fluctuations in rainfall and water availability has been investigated through field surveys and remote sensing data, and its effectiveness and limitation under changing climate have been investigated. With results from these two approaches, the effective information for adaptation in agriculture under climate change has been distilled and discussed.

Radiosonde observation in Cambodia was conducted in this project, since there is currently no operational one. The sondes were released simultaneously from two stations in Cambodia, from paddy and from the Tonle Sap Lake. The observed data were used for the data assimilation for the regional climate model simulations with WRF, in order to clarify the mechanism of the locally-induced nocturnal precipitation over the rain-fed agricultural area at western country.
Through the comparison with the observed precipitation both from satellite and ground, it was shown that the simulated precipitation by WRF with data assimilation has been improved even only with day-time observation data. The simulated results also showed that not only night-time phenomena but also the development of the day-time lake-breeze circulation as well as the surface heat fluxes from various land-use types over land during daytime are the key for the better estimation of the nocturnal local precipitation in this region. -
