What is the primary purpose of agricultural biotechnology?

The primary purpose of agricultural biotechnology is to improve crop yield and resilience. This is achieved by using biotechnological techniques, such as genetic modification or marker-assisted selection, to create plants that can withstand various stresses, such as drought, pests, and diseases. By enhancing the genetic traits of crops, agricultural biotechnology aims to ensure food security by producing more food on existing arable land, ultimately benefiting farmers and consumers alike.

Other options, while related to agricultural practices, do not directly capture the essence of agricultural biotechnology's primary objectives. For instance, increasing the use of chemical fertilizers is contrary to the goals of sustainability that biotechnology often promotes, as it seeks to reduce dependency on chemical inputs. Promoting organic farming practices is a different approach that may not necessarily involve biotechnological advancements. Lastly, reducing agricultural land usage can be a consequence of improved crop yields but is not a direct intention of agricultural biotechnology itself; rather, the focus is primarily on enhancing productivity and resilience within the current agricultural systems.
