Technology’s Impact on Food Production

Chapter 19 examines how technological advancements have enabled exponential growth in food production, disproving Thomas Malthus’s prediction that population growth would outpace food supply. Wheat yield per acre rose slowly from 0.18 tons in 8000 BCE to 1.8 tons by 1950, then surged to 5.7 tons in 2020—a threefold increase in 70 years with a doubling time of 42 years. This rapid rise was driven by innovations in plant breeding, genetic modification, synthetic fertilizers, pest control, mechanization, irrigation, soil management, and precision agriculture using data analytics. Alongside yield improvements, arable land expanded dramatically, increasing by a factor of 15 over the last 200 years, aided by mechanization and irrigation technologies. While these advances have ensured food supply keeps pace with population growth, they often come at the cost of deforestation, reducing carbon capture and exacerbating climate change.
