Rice Villages

Rice Villages are dominated by the cultivation of paddy rice and usually have fairly high population density.  The majority of the regions classified as rice villages are in Asia and all of the top five constituent Olson ecoregions that comprise the rice village anthrome, which cover nearly 54% of all rice villages are found in India and China. 

Rice Villages are generally wet environments but range in temperature from temperature to tropical.  It follows that a great deal of the land is cultivated (median 73.1% mostly for rice) and very little land use goes to pasture (median 0.6%). 

Despite the significant rainfall experienced by most rice villages the land is still heavily irrigated primarily by channeling rain water to rice paddies.
