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.
Laos
Subsistence agriculture still accounts for half of the GDP and provides 80 percent of employment. Only 4.01 percent of the country is arable land, and a mere 0.34 percent used as permanent crop land, the lowest percentage in the Greater Mekong Subregion. Rice dominates agriculture, with about 80 percent of the arable land area used for growing rice. Approximately 77 percent of Lao farm households are self-sufficient in rice.
