Dryland agriculture

Japanese: 乾燥地農業 - かんそうちのうぎょう

Also known as dryland agriculture or arid agriculture. This is field agriculture carried out in areas with little rainfall, without drawing water. It is characterized by preventing rainwater runoff, suppressing soil moisture evaporation, and storing as much water as possible in the soil so that the crops can use it effectively. Dryland agriculture was used in the past along the Mediterranean coast and in southern Russia, and has been improved in modern grassland development in the United States, and this farming method has expanded the cultivation areas of wheat and other crops to semi-arid regions around the world. →Irrigation

乾地農業，乾燥農業とも。雨量の少ない地方で，特に引水せずに行う畑作農業。雨水の流失を防ぎ，土壌水分の蒸発を抑え，できるだけ多くの水を土壌中に貯えて作物にその水を有効利用させるのが特徴。古くは地中海沿岸，南ロシアなどで，また近代米国の草地開拓でも改善された乾地農法が用いられ，小麦などの栽培圏はこの農法により世界の半乾燥地域へ拡大した。→灌漑(かんがい)
