Precision agriculture is at the vanguard of this data revolution. It’s a rapidly developing area where information is being applied to food production and land cultivation to dramatically improve productivity and reduce harm to the environment. In arable farming, for example, this approach enables farmers to gather a wealth of real-time information: water and nitrogen levels, air quality, disease—data that isn’t just specific to each farm or to each acre, but to each square inch of our farmland. Using this information, algorithms can tell the farmer exactly what each square inch of land needs and when and, with pinpoint precision, produce the maximum possible yield.
