Utilization of durum wheat landraces in East Shewa, central Ethiopia: Are home uses an incentive for on-farm conservation?

摘要

The study was conducted in East Shewa, central Ethiopia, where durum wheat landraces were once popular, but were displaced and re-introduced. Combinations of survey techniques are employed to document the different home uses of durum wheat landraces and to assess whether these serve as an incentive to on-farm conservation. The findings reveal that wheat landraces have multiple dietary and sociocultural uses that contribute to the maintenance of landraces on-farm. Temporal analysis of historical information showed that (1) richness in food traditions is associated with a high level of landrace diversity on-farm; (2) food traditions in East Shewa did not change radically as a result of the integration of farmers into the market economy; and (3) farm households still have an appreciation of, and a preference for, the home-use related qualities of the landraces, this despite their long term disappearance and the subsequent availability of several improved wheat varieties. The study illustrates the relationship between the local availability of landrace wheats and their on-farm survival. The home uses of landraces plays an instrumental role in the promotion of on-farm (iin situ) conservation. Augmenting conservation activities with non-breeding approaches (e.g., awareness-creation) would support the survival of wheat landraces for the foreseeable future.
