ABSTRACT
This chapter focuses on the light environment as it directly affects agroecosystems. The light environment includes that portion of the electromagnetic spectrum from the invisible ultraviolet (UV), through the visible light spectrum to the invisible infrared (IR). This chapter also discusses how the light environment can be managed to more efficiently channel this renewable source of energy through the system, use it to maintain the many and diverse functions of the system, and ultimately convert part of it into sustainable harvests.
