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.
Environmental issues in Japan
The massive nationwide rebuilding efforts in the aftermath of World War II, and the development of the following decades, led to even further urbanization and construction. The construction industry in Japan is one of its largest, and while Japan maintains a great many parks and other natural spaces, even in the hearts of its cities, there are few major restrictions on where and how construction can be undertaken. Alex Kerr, in his books "Lost Japan" and "Dogs & Demons", is one of a number of authors who focuses heavily on the environmental problems related to Japan's construction industry, and the industry's lobbying power preventing the introduction of stricter zoning laws and other environmental issues.
