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.
Economy of Kenya
The agricultural sector continues to dominate Kenya's economy, although only 15 percent of Kenya's total land area has sufficient fertility and rainfall to be farmed, and only 7 or 8 percent can be classified as first-class land. In 2006 almost 75 percent of working Kenyans made their living on the land, compared with 80 percent in 1980. About one-half of total agricultural output is non-marketed subsistence production. Agriculture is the second largest contributor to Kenya's gross domestic product (GDP), after the service sector. In 2005 agriculture, including forestry and fishing, accounted for about 24 percent of GDP, as well as for 18 percent of wage employment and 50 percent of revenue from exports. The principal cash crops are tea, horticultural produce, and coffee; horticultural produce and tea are the main growth sectors and the two most valuable of all of Kenya's exports. In 2005 horticulture accounted for 23 percent and tea for 22 percent of total export earnings. Coffee has declined in importance with depressed world prices, accounting for just 5 percent of export receipts in 2005. The production of major food staples such as corn is subject to sharp weather-related fluctuations. Production downturns periodically necessitate food aid—for example, in 2004 aid for 1.8 million people⎯because of one of Kenya's intermittent droughts. However, the expansion of credit to the agricultural sector has enabled farmers to better deal with the large risk of agriculture based on rainfall and the dramatic fluctuations of the prices of agricultural products.
