Junta Yanai is a professor in the Graduate School of Life and Environmental Sciences at Kyoto Prefectural University, Japan. His research interests include evaluation and management of soil fertility in the temperate and tropical regions, spatiotemporal analysis of soil properties, and rehabilitation of agricultural soils contaminated with radiocesium or heavy metals. He is a council member of the Japanese Society of Soil Science and Plant Nutrition, a board member of the Japanese Society of Pedology, and vice chair of Commission 3.5 of the International Union of Soil Sciences (IUSS) (2018–2022). Sota Tanaka is a professor in the Faculty of Agriculture and Marine Sciences, Kochi University, Japan. His research interests include evaluation of the changes in soil fertility in Southeast Asian countries with special reference to alternating socioeconomic circumstances and appropriate soil management systems ofagriculturalfields in mountainous regions in Japan. He is a board member of the Japanese Society of Soil Science and Plant Nutrition, and also a board member of the Japanese Society of Pedology. Shin Abe is a junior associate professor at the Experimental Farm, Kindai University, Japan, and an associate fellow at the Universiti Teknologi MARA (UiTM) Pelis Branch, Malaysia. His major research interest is soil management for sustainable crop productivity enhancement and biodiversity conservation in tropicalagroecosystems. Atsushi Nakao is an associate professor in the Graduate School of Life and Environmental Sciences of Kyoto Prefectural University, Japan. His research interests include pedogesis related to soil functions, mineralogical control on radionuclide dynamics in soils, and serpentine soil diversities in humid Asia. He is a board member of the Japanese Society ofSoil Science and Plant Nutrition, and also a board member of the Japanese Society of Pedology.
