City farming
Victory gardens were city farms that sprang up during World War I and World War II. There were food shortages in the United States, the United Kingdom, Canada, Australia and Germany. In the US alone, victory gardens provided 40% of the produce used during World War II. In addition to farms, gardens were grown in window boxes, rooftops, back yards and vacant yards. Victory gardens gave the people at home a sense of  doing their part for the war effort. Women in England tended to grow ornamental gardens. This made for an easy shift towards food gardening. Women in the US had a cultural identity with the British and also grew ornamental gardens. But there were stereotypes to working in agricultural jobs in the US. But these were quickly overcome. Victory gardens were not uncommon even among upper classes in America.
