During the 21st century, the world is experiencing the most evident effects of climate change, such as desertification, rising temperatures, higher frequency of extreme meteorological events, rising sea levels, and lack of potable water. Furthermore, the world population is constantly growing and is expected to reach almost 10 billion by 2050. In this scenario, agriculture is severely challenged due to the increasing demand for food and the worsening of environmental conditions: new techniques are needed to improve the yield of plantations by saving as many valuable resources, such as water and energy, as possible. The field of smart agriculture is working in this direction, and it is developing technologies that can make farming more efficient and autonomous.
