Since Taiwan is a mountainous island, the arable land is limited. To expand arable land and increase agricultural production, the Republic of China government has encouraged farmers to open up new areas and make use of marginal lands. Under a long-term research program, the acreage of the arable lands has increased.
台灣山多地少，可耕地面積有限，但政府為增加耕地面積並擴大農業生產，積極鼓勵開墾與利用各類邊際土地，使得可耕地面積日益提高。
