In the readings of North American Odyssey, stimulus diffusion is discussed and exemplified through the expansion of rice farming techniques in Africa to the Carolinas and Georgia Lowcountry through the Trans-Atlantic Slave Trade. Many of the techniques, such as sluice gates, were carried over from Africa to the United States. The Atlantic Ocean acted as a permeable barrier by allowing the spread of ideas through, while also filtering out certain methods of rice farming. Time-Distance Decay is also a reason for the spread of these ideas filtering out. When examining the fields, I came across findings that the rice plantations in the Carolinas and Georgia Lowcountry are larger than the rice fields in Africa. I averaged the perimeters of the rice fields as well as their area in meters squared...
