And improving the resistance of crops to drought, salinity, and cold will increase arable land area, as crops could be planted in locations that were not formerly suitable, such as low-lying coastal zones subject to seawater incursion, for example, or areas with cold weather.
而增加作物的耐旱、耐鹽、耐寒性，則可以擴充耕地面積，使得原來不適合栽種作物的地方，如低窪的海水倒灌區及溫度偏冷的山區，也可以種植作物。
