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.
Economy of Poland
Agriculture employs 12.7% of the work force but contributes 3.8% to the gross domestic product (GDP), reflecting relatively low productivity. Unlike the industrial sector, Poland's agricultural sector remained largely in private hands during the decades of real socialist rule. Most of the former state farms are now leased to farmer tenants. Lack of credit is hampering efforts to sell former state farmland. Currently, Poland's 2 million private farms occupy 90% of all farmland and account for roughly the same percentage of total agricultural production. Farms are small—8 hectares on average—and often fragmented. Farms with an area exceeding 15 ha accounted for 9% of the total number of farms but cover 45% of total agricultural area. Over half of all farm households in Poland produce only for their own needs with little, if any, commercial sales.
