WICHITA, Kan. (AP) — The Kansas Department of Agriculture is joining with farm groups to focus public attention on the state’s role in feeding a growing global population.

National Geographic photographer Jim Richardson is headlining an event March 18 at Kansas State University’s Union Little Theatre with a visual journal that aims to highlight the topic “Feeding a Hungry Planet.” The program is part of the state’s celebrations of Kansas Agriculture Month.

A group of Kansas agriculture experts will follow Richardson’s lecture to talk about the state’s agricultural industry. Kansas is the nation’s biggest producer wheat and grain sorghum.
