Rice Production

Rice is grown in more than a hundred countries, with a total harvested area of approximately 158 million hectares, producing more than 700 million tons annually (470 million tons of milled rice). Nearly 640 million tons of rice are grown in Asia, illustrating 90% of global production. Sub-Saharan Africa generates about 19 million tons and Latin America some 25 million tons.  Almost all rice is grown on small farms of 0.5−3 ha, In Asia and Sub-Saharan Africa.

Yields range from less than 1 t/ha beneath very poor rainfed conditions to more than 10 t/ha in intensive temperate irrigated systems. Small, and in many areas retiring, farm sizes account for the low incomes of rice farm families. Rice grows in a wide range of environments and is productive in many situations where other crops would fail. 

The highest rice yields have traditionally been acquired from plantings in high-latitude areas that have long day length and where intensive farming techniques are practiced, or in low-latitude desert areas that have very high solar energy. Southwestern Australia, Hokkaido in Japan, northern California, Spain, Italy and the Nile Delta provide the best examples.
