How does rice farming affect climate change?

Rice feeds half of the world’s population on a daily basis, but it is also an important driver of global warming. … “Rice grows mostly in flooded fields called rice paddies. The water blocks oxygen from penetrating the soil, creating ideal conditions for bacteria that emit methane.

How rice cultivation is the cause of climate change?

The burning of rice residues such as straw and husks also contributes to greenhouse gas emission. Similarly the inefficient application of nitrogen fertilizers in rice production systems promotes the release of nitrous oxide, a potent greenhouse gas, into the atmosphere.

Is rice bad for climate?

Rice has the highest climate impact of any crop by calorie. Besides using a large amount of land and water, the biggest problem with rice is the methane emitted from the flooded rice paddies. … From rice paddies, this added greenhouse gas is the equivalent to adding 1,200 coal-fired power plants.

What is the impact of climate change on rice production?
