Japan Agriculture and Cuba Agriculture

A fast check of the CIA factbook shows me that Cuba and Japan have roughly equivalent amounts of arable land.  Cuba is a third the size of Japan, but have about a third of the land arable, while Japan has about 10 percent.  John Phipps points to a piece on Cuba here, which includes the statement that Cuba imports 70 to 80 percent of its food. Meanwhile, Modern Farmer has a piece on Japanese agriculture after the Fukushima tsunami.

Though reforms instituted in the aftermath of World War II had drastically improved the California-size country’s self-sufficiency, the ensuing decades saw farmers abandoning the profession in droves. In 1965, 73 percent of the calories consumed in Japan were being produced there, compared with only 39 percent by 2010. During that same period, the area of land being cultivated had shrunk from 15 million to 11 million acres. The average age of a Japanese farmer climbed from 59 to 66 between 1995 and 2011.[emphasis added]

According to the CIA factbook, Cuba's population is 11 million, Japan's 126 million. Bottom line: Japanese agriculture is several times more productive than Cuba's.
