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 Uzbekistan
Agriculture in Uzbekistan employs 28% of the country's labor force and contributes 24% of its GDP (2006 data). Crop agriculture requires irrigation and occurs mainly in river valleys and oases. Cultivable land is 4.5 million hectares, or about 10% of Uzbekistan's total area, and it has to be shared between crops and cattle. Desert pastures cover fully 50% of the country, but they support only sheep.
