The distribution range of agriculture is very vast. Almost all of the earth's surface can be used for agricultural production except the poles and deserts. Of the actual land area of ​​nearly 131 million square kilometers, about 11% is arable land and perennial crop land, 24% is grassland and pasture, 31% is forest and woodland, and oceans and inland waters are the places for aquaculture production.
