New ideas in agricultural technology Ever since human beings began to till the soil, agricultural reformers have fretted over the question of how to raise enough food on the world's limited supply of arable land to fill its seemingly innumerable bellies.
其他如加拿大、俄羅斯、北歐等寒冷國度，或是中東、非洲等沙漠地帶，氣候不是太過寒冷，就是缺水，根本無法用傳統方式栽培農作物，完全控制型的設施農業也能發揮很大效益。農業科技新思維打從人類懂得農耕以來，如何靠有限耕地的作物餵飽無窮盡的胃，一直是農業改革的重要課題。
