Rice Paddy Terraces / Rice produces methane
The fields require large quantities of water for irrigation. Flooding provides water essential to the growth of the crop. Water also provides a favorable environment for the rice strains being grown as well as discouraging the growth of many species of weeds. The water buffalo is the only draft animal adapted for life in wetlands so they are extensively used in paddy fields.
Growing rice has an adverse environmental impact because of the large quantities of methane gas it generates.
This level of greenhouse gas generation is a large component of the global warming threat produced from an expanding human population. However, recent studies have shown that methane can be significantly reduced while also boosting crop yield by draining the paddies.
The word "paddy" is derived from the Malay word padi, rice plant.
