well, typical rice farming...lots of pesticides, chemicals and stuff. Monoculturing all year long, rice always under water.
i just read the book of masanobu fukuoaka, and he said: dont care about the bug, he will eat that what he needs, the rest of the plants will get more sun by that and the plants get stronger and bigger, in fact the crop is the same whatever you use chemicals or let the bugs live.
this is how the field looks like in times wheres no rain:
