Heald finds no overall loss of vegetable diversity in the 20th century
In a recent study, Georgia Law Post Professor Paul J. Heald and Susannah Chapman, a Ph.D student in the anthropology department, compared the availability of varieties in commercial vegetable seed catalogs in 1903 to those available in 2004. Their results argue against the conventional wisdom that the 20th century was a disaster for vegetable crop diversity.
