Jasmine rice (; ; ), sometimes known as "Thai fragrant rice", is a long-grain variety of rice that has a nutty aroma and a subtle "pandan"-like ("Pandanus amaryllifolius"-leaves) flavor caused by 2-Acetyl-1-pyrroline.
Jasmine rice is originally from Thailand.
It was named as Kao Dok Mali 105 variety (KDML105) by Sunthorn Seehanern, an official of the Ministry of Agriculture in the Chachoengsao Province of Thailand in 1954.
The grains will cling when cooked, though it is less sticky than other rices as it has less amylopectin.
It is also known as Thai Hom Mali.
To harvest jasmine rice, the long stalks are cut and threshed.
The rice can then be left in a hulled form and sold as brown rice or shucked and sold as white rice.
Most Southeast Asians prefer the white variety of jasmine rice.
Particular varieties of US-grown rice have been found to contain higher levels of arsenic due to the historical use of arsenic based pesticides in some parts of the country.
Rice from Thailand and India contains the least arsenic among rice varieties. 
The agriculture in Thailand is highly competitive, diversified and specialised and its exports are very successful internationally.
Rice is the country's most important crop; Thailand is a major exporter in the world rice market.
Other agricultural commodities produced in significant amounts include fish and fishery products, tapioca, rubber, grain, and sugar.
Exports of industrially processed foods such as canned tuna, pineapples, and frozen shrimp are on the rise.
The northern Thailand is home to Black Ivory coffee. 
The Lesser Rice-field Rat (Rattus losea) is a species of rodent in the family Muridae.
It is found in China, Laos, Taiwan, Thailand, and Vietnam. 
Helcystogramma arotraeum is a moth in the family Gelechiidae.
It was described by Meyrick in 1894.
It is known from Japan, China, Myanmar, Thailand, northeastern India, Sri Lanka, Malaysia, and Indonesia.
The larvae feed on the rice plant "Oryza sativa" and Manchurian wild rice ("Zizania latifolia"). 
Rice cultivation on wetland rice fields is thought to be responsible for 1.5% of the anthropogenic methane emissions.
Rice requires slightly more water to produce than other grains.
Long-term flooding of rice fields cuts the soil off from atmospheric oxygen and causes anaerobic fermentation of organic matter in the soil.
Methane production from rice cultivation contributes ~1.5% of anthropogenic greenhouse gases.
Methane is twenty times more potent a greenhouse gas than carbon dioxide.
A 2010 study found that, as a result of rising temperatures and decreasing solar radiation during the later years of the 20th century, the rice yield growth rate has decreased in many parts of Asia, compared to what would have been observed had the temperature and solar radiation trends not occurred.
The yield growth rate had fallen 10–20% at some locations.
The study was based on records from 227 farms in Thailand, Vietnam, Nepal, India, China, Bangladesh, and Pakistan.
The mechanism of this falling yield was not clear, but might involve increased respiration during warm nights, which expends energy without being able to photosynthesize.
