With some 20.4 million hectares (50.4 million acres) of farm land, of which about 10 million hectares (24.7 million acres) are under rice cultivation, Thailand continues to rely heavily on agriculture, although the country has suffered from declining export prices in recent years. Rice is the major crop grown; Thailand is the world's biggest rice exporter. Total rice production amounted to 17.5 million tons in 2001/02.
