Explanation:
Mechanized culture uses plows to turn grasslands into farms
Climate changes so farms can no longer be sustained
Farmers migrate away
New irrigation technology brings farmers back
One critical aspect that affects population dynamics is the human - environment interaction which is mostly seen in farming activities.
Mechanized farming practices are not sustainable. They use a lot of nutrients in the soil and apply chemicals to crops to maximize outputs. Also farm machinery produce greenhouse gases that leads to global warming eventually climate change.
This can cause the occurrence of drought and farming is no longer possible. Farmers will emigrate from such an area in search for more arable lands.
Development of new irrigation technology is an incentive to bring farmers back into their abandoned farms.
