What people built to ensure commercial farms could be used mostly for the war effort

During the world war 1, farming was an essential part of war effort. It was absolutely necessary to keep the soldiers fed because the country's resources were already being drained in the war fare.

People helped with the food epidemic by growing their own small gardens. They grew their own food so that the commercial farms could focus on feeding the soldiers at war.

This gave a huge cushion to the state in terms of producing sufficient food for the country.
