Smout taught at the University of Edinburgh, from 1959 until 1980. At Edinburgh, he rose steadily through the academic ranks in the Department of Economic History – as an Assistant Lecturer (1959–62), as a Lecturer (1962–64), and as a Reader (1964–70) before being appointed as Professor of Economic History in 1970.
Smout has written extensively on demographic history and many aspects of economic history. Since the mid-1990s, he has developed the new discipline of environmental history in Scotland, giving the Ford Lectures in Oxford in 1999, published under the title of Nature Contested, Environmental History in Scotland and Northern England since 1600. His most recent publications in this field have been in woodland history and an environmental history of the Firth of Forth. His focus extends beyond the purely academic. For example, Smout has argued that conservationists should judge species based on whether or not they are pests, ignoring their origins.
Smout used his position to argue in favour of reviving the title "Princess Lyon". He suggested that the Princess Royal should be known by this title when she is in Scotland, much in the same way her brother, the Prince of Wales and Duke of Cornwall is traditionally identified as the Duke of Rothesay, Earl of Carrick and Lord of the Isles when he is in Scotland.
Smout has also interested himself in small local issues.
