It hosts some 1,600 rice-production facilities, making it the main supplier of rice to the entire country. With a cultivated area of more than 1,065,000 hectares (more than 4,000 square miles), rice growing generates nearly 200,000 jobs. Seventy percent of the area uses pumps for irrigation, some of which operate with diesel engines, with resultant air and water contamination. Rice production in Rio Grande do Sul is responsible for an estimated 20 percent of Brazil's production of methane, a greenhouse gas. Fields flooded for rice cultivation are readily visible in the 2008 image as blue parcels, which are absent from the 1975 image. Source: United Nations Environment Programme (UNEP).
