Losses of wheat, rice and maize to insects could increase by 10 to 25% per degree Celsius of climate warming, according to this paper. This is due to two main factors: insects have faster metabolisms at higher temperatures and therefore need to eat more; and insect population growth rates will also change with temperature.

California agritech startup Iron Ox has unveiled an “autonomous farm”, where robots move plants and transplant them from one stage to the next.
