As a result of all these transformations, the agri-food sector now creates a quarter of human-produced greenhouse gas emissions—a share expected to increase to a half of all such emissions by 2050—while another 8 percent of emissions results from non-food agriculture and deforestation, according to the ipcc’s 2019 special report on climate change and land and the eat-lancet commission.
The combination of advancing climate change and an already-vulnerable industrial system is a “perfect storm” that threatens farmers’ livelihoods and our food supply. The good news is that there are tools—in the form of science-based farming practices—that can buffer farmers from climate damage and help make their operations more resilient and sustainable for the long term.
The links between industrial agriculture and climate change are twofold. On the one hand, the crops grown in the genetically homogeneous monocultures that are typical of chemical farming are vulnerable to the climate extremes that are becoming more frequent and more violent as a result of global warming.
According to the epa as temperatures rise, both the productivity and nutritional value of crops may decrease. Other government studies show that there may be less milk available to consumers, because dairy cows are sensitive to heat stress.
