Specialists classify farming technologies into four generations. Agriculture 1.0 describes the traditional farming methods used for millennia, characterized by minimal use of technology and low productivity. This changed in the early twentieth century with the introduction of mechanization and crop science in farming, in what is referred to as agriculture 2.0. More recently, the use of advanced technologies such as telemetry, sensors, and satellite tracking systems created what is known as agriculture 3.0. Now, a new generation of technologies is ushering in the next revolution, called agriculture 4.0, by enabling integration and real-time connectivity between the different technologies shown on the following pages.
