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 cultivated.
Agriculture in Armenia
Armenia has 2.1 million hectares of agricultural land, 72% of the country's land area. Most of this, however, is mountain pastures, and cultivable land is 480,000 hectares (452,900 hectares arable land, 27,300 hectares in orchards and vineyards), or 16% of the country's area. In 2006, 46% of the work force was employed in agriculture (up from 26% in 1991), and agriculture contributed 21% of the country's GDP. In 1991 Armenia imported about 65 percent of its food.
