専門分野：土壌浸食と流域管理

地球上に存在する乾燥地の実に３分の１が、砂漠化、土壌劣化、水不足の影響を受けています。これらは、気候変化や人口増加のシナリオを考えると、土壌や水源の持続困難な利用によってさらに悪化すると考えられます。水質、土壌、植生、そしてガス排出問題の悪化は自然資源の利用と農業生産効率の向上を同時に図る持続可能な土地管理(SLM)により食い止めることができます。持続可能な土地管理への様々な取り組みがなされていますが、SLMの異なった状況下に対する影響の明確化と最適化が必要とされています。さらに、新技術の開発も必要とされています。私の目標は、教育と研究を通し、地形の変化による外力への感度を理解し適切なSLMを開発することにより、「2030年までに土地荒廃化中立社会をつくる」(SDGs-15.3より引用)という目標の実現に貢献することです。研究では、圃場や実験室での試験と観察を含めた、実地踏査とマッピング、社会経済調査、気候、土地利用と人口増加シナリオの作成、世界各地での空間分析と水文・浸食モデリングをはじめとした統合的なアプローチを行います。
