What refers to lands that are serviced by irrigation facilities?

The term that accurately describes lands serviced by irrigation facilities is "irrigated land." These lands have infrastructure in place, such as canals, pipes, or other water delivery systems, which allow for the controlled application of water to crops. This irrigation process is essential in enhancing agricultural productivity, particularly in areas where rainfall may be insufficient or unreliable.

Irrigated land provides farmers with the ability to grow crops in a more controlled environment, improving yields and enabling the cultivation of a wider variety of crops throughout different seasons. It contrasts with "arable land," which refers to land capable of being plowed and used for growing crops, but does not specifically indicate the presence of irrigation facilities. Similarly, "irrigable land" signifies land that is capable of being irrigated rather than land that is currently benefiting from irrigation, while "agricultural land use" is a broader term that encompasses all types of agricultural practices, including both irrigated and non-irrigated land. Thus, "irrigated land" is the precise term for lands actively serviced by irrigation systems.
