The world's rice production would be significantly increased because terraces increase rice production in China

Explanation:

China does utilize terrace farming and has done so for hundreds of years. It has improved the output of rice by improving the farming conditions, especially on mountainous terrain where long, flat fields are impossible to create. Terraces also helped rice farming through water conservation. In the mountainous areas in China where rice is grown, rain is abundant, and the terraces help to evenly distribute that water across all the crops. All of this impacted the sustainable development of China's agricultural market.
