Management of local breeds is closely linked to the global challenges involved in genetic resources management. However, it cannot be reduced to this genetic dimension alone and is an integral part of the entire farming system of which it is a part. The aim of this paper is to show why it is essential to have an approach to local breed management that takes the dynamics of livestock farming systems (LFS) into account. After a presentation of the LFS approach, we show how genetic management is strongly linked to other dimensions of farming systems, at the farm scale as well as at more comprehensive scales. We illustrate our claim with different examples of the management of local breeds of different species.
