How is most of the work on rice farms in Southeast Asia accomplished?

Answer 1

Many Southeast Asian farmers, like farmers elsewhere in Asia, use traditional agricultural methods. They plant by hand and harvest with sickles and other hand tools. Many use water buffaloes to pull large rakelike tools that plow the paddies (rice fields). However, the use of modern farm machines, high-yielding seeds, and chemical fertilizers and pesticides is becoming more common.

Hope this helps!

Answer 2

because in Southeast Asia, technology worms are common, and machines are to expensive for the farmers to have them eaten.
