Answer 1

Answer:

hope it helps

The successful use of chemical fertilizers and pesticides depends on two factors: 1. do you have an intensive export oriented agriculture or more subsistence / local farming?

2. How important is agribusiness for the whole economy in your region? Can the consumers afford organicly farmed products? Or are the people willing to accept the impact of the chemicals?

I think the use of chemicals differs a lot depending ond region and product that is farmed. And any change will differ as much. Asking both questions should give you a rather prcise answer for the region you are looking at.
