This chapter revisits the debates of the late 1980s on colonial conservation and development within the settler agrarian environment during the first half of the twentieth century in Southern Africa. It uses the debates on conservation to analyse the post-war tobacco boom in Southern Rhodesia and how it altered farming landscapes and ideologies about conservationism amongst white settler farmers. The chapter discusses how production practices and systems in the tobacco farms evolved during the post-war years and how this evolution transformed the settler agricultural environment between 1947 and 1960.
