The number of Japanese farm households and farm population has declined in recent decades, as has rice production. The decline came about because in 1969, the Ministry of Agriculture, Forestry, and Fisheries has asked farmers to reduce rice acreage; under the Staple Food Control Act of 1942 the Japanese government is formally in charge of all ...
The problem of surplus rice was further aggravated by extensive changes in the diets of many Japanese in the 1970s and 1980s. Even a major rice crop failure did not reduce the accumulated stocks by more than 25% of the reserve. In 1990, Japan was 67% self-sufficient in agricultural products and provided for around 30% of its cereal and fodder ...
Rice production by country (2019) This is a list of countries by rice production in 2022 based on the Food and Agriculture Organization Corporate Statistical Database. The total world rice production for 2022 was 776,461,457 [1] metric tonnes. In 1961, the total world production was 216 million tonnes.
While the rice crisis did occur at the same time as the 2007–2008 world food price crisis, Tom Slayton has argued the spike in rice prices are a special case. [2] Slayton argues that the price increases were a result of rising oil and petrochemical prices (peaking in July 2008); and export restrictions by a number of countries. [2]
In the wake of the two oil crises of the 1970s (1973 and 1979), Japan made efforts to diversify energy resources in order to increase energy security. Japan's domestic oil consumption dropped slightly, from around 5.1 million barrels (810,000 m 3) of oil per day in the late 1980s to 4.9 million barrels (780,000 m 3) per day in 1990
Predictions of climate change's effects on rice cultivation vary. Global rice yield has been projected to decrease by around 3.2% with each 1 °C increase in global average temperature [64] while another study predicts global rice cultivation will increase initially, plateauing at about 3 °C warming (2091–2100 relative to 1850–1900). [65]
Cereal production more than doubled in developing nations between the years 1961–1985. [81] Yields of rice, corn, and wheat increased steadily during that period. [81] The production increases can be attributed equal to irrigation, fertilizer, and seed development, at least in the case of Asian rice. [81]
Even before this Australia's rice production greatly exceeded local needs, [91] and rice exports to Japan have become a major source of foreign currency. Above-average rainfall from the 1950s to the middle 1990s [ 93 ] encouraged the expansion of the Riverina rice industry, but its prodigious water use in a practically waterless region began to ...
