The study looked at production in terms of inputs, including labor, fertilizer, machinery, and the output in terms of food. It used a model to see how climate change has affected this relationship.
Although farming has become much more productive in recent decades, heatwaves are becoming increasingly threatened, which fatigues farm workers and cause some crops to wilt. Drought and severe weather events may also affect a farm s production, particularly in poorer countries.
Via degradation of pasture land, depletion of fertile topsoil, chemical emissions, and the emission of large quantities of greenhouse gases that lead to global warming, the intensification of farming to increase productivity has caused significant environmental harm.
