Despite assumptions that agriculture will automatically go into a mode of decline at the Rural Urban Interface (RUI), official statistics suggest that agriculture as a whole remains a strong (and in some cases a growing) industry in many U.S. RUI counties. RUI scholars have acknowledged internal family dynamics can significantly influence farm persistence and adaptation strategies, however, few studies have sought to document the specific role succession has on farm structure at the RUI. Building off rural geography models of farm organization at the RUI and succession research embedded in rural studies we analyze interviews from 33 U.S. farm families to 1) explore the relationship between farm adaptation and succession at the RUI, and 2) examine how succession is related to the different types of enterprises found at the RUI (direct marketers vs. commodity producers) and the types of growth strategies these farm families implement. We find that families who can not identify an heir either disinvest or enter a static management mode. Among farm families who can identify an heir we identify a variety of horizontal and vertical growth strategies (expanding, intensifying, and entrepreneurial stacking) designed to achieve farm reproduction goals. We discuss the theoretical and policy related implications of this research. (Contains 1 figure and 3 tables.)
