Economy of Japan
The Japanese agricultural sector accounts for about 1.4% of the total country's GDP. Only 12% of Japan's land is suitable for cultivation. Due to this lack of arable land, a system of terraces is used to farm in small areas. This results in one of the world's highest levels of crop yields per unit area, with an overall agricultural self-sufficiency rate of about 50% on fewer than 56,000 km² (14 million acres) cultivated.
Agriculture in the United Kingdom
The agricultural area used is 17.2 million hectares, about 70% of the land area of the United Kingdom. 36% of the agricultural land is croppable (arable), or 25% of the total land area. Most of the rest is grassland, rough grazing, or woodland. However, historic Government figures for the area of agricultural land may be wrong and the true figure may be 9.34 million hectares.
