"The gentle lowing of cattle is the first thing a visitor to District 10 hears. This region raises strong, healthy livestock, which becomes the meat that helps us raise strong, healthy children of Panem."
―Description from The Hunger Games: Tribute Guide
District 10 is one of the poorer of the thirteen districts of Panem. Its main industry is livestock, and provides beef for the Capitol. Since they are in charge of livestock, it can be assumed that the majority of District 10 is farmland.
