Summary

General trends of development imply an increasing uniformity of animal genetic resources, caused by the loss of endangered breeds and increased inbreeding within commercial breeding populations. The implications of these trends point to a reduction in the genetic diversity of the animal genetic resources, which may reduce possibilities for utilization in the future, while at the same time a dramatic change in environmental production conditions can be observed. In order to change this developmental trend, sustainable management of animal genetic resources must be promoted globally. The fundamental issues for such sustainable management are illustrated by the principles given in the Convention on Biological Diversity. In order to accomplish sustainable management of these resources, the following actions must be taken:

• The development of policies to promote national and global responsibility for maintaining genetic diversity, which will not be addressed within this paper

• The development of knowledge as a fundamental concept to impose sustainable management principles on these animal genetic resources. This will be dealt with in this paper. A more complete description of these features can be found in Woolliams et al, 2005 in (Sustainable Management of Animal Genetic Resources).

Résumé

Les tendances générales de développement actuel prévoient une uniformité des ressources génétiques animales, due, d'une part, à la perte des espèces menacées d'extinction et d'autre part, au développement des croisements génétiques au sein des populations commercialisées pour l'élevage. Ceci mène à une restriction de la diversité génétique des ressources animales, ce qui pourrait compromettre leur utilisation possible à l'avenir. A côté de cela, les conditions environnementales de production sont également radicalement changeantes. Pour pouvoir faire évoluer ce mode de développement de manière positive, il est plus que nécessaire d'imposer un management durable des ressources génétiques animales, à l'échelle mondiale. Le fondement d'un tel développement durable est mis en avant par les principes cités par la Convention sur la Biodiversité. Pour atteindre un management durable de ces ressources, certaines conditions sont nécessaires:

• Une responsabilité à la fois nationale et internationale pour conserver la diversité génétique - règles, qui ne seront pas traitées dans ce document

• Développer les connaissances, fondement de base pour imposer le développement durable de ces ressources génétiques animales; sujet qui sera débattu ici. Une plus complète description de ce dispositif peut être consultée dans Woolliams et al., 2005 (Sustainable Management of Animal Genetic Resources).

Resumen

Las tendencias generales de desarrollo actualmente preven una uniformidad de los recursos zoogenéticos debido, por una parte a la pérdida de especies en vía de extinción y por otra al desarrollo de cruces genéticos dentro de las poblaciones para comercialización. Esto nos lleva a una restricción de la diversidad genética de los recursos animales, lo que podría comprometer su utilización en el futuro. Al mismo tiempo las condiciones ambientales de producción también están cambiando radicalmente. Para permitir la evolución de este tipo de desarrollo de manera positiva, será necesario imponer una gestión sostenible de los recursos zoogenéticos a escala mundial. La base de este desarrollo sostenible se recoge dentro de los principios estipulados en la Convención para la Biodiversidad. Para alcanzar una gestión sosteni de estos recursos son necesarias ciertas condiciones:

• Responsabilidad tanto nacional como internacional para la conservación de la diversidad genética - normas que no tratarem en este documento.

• Desarrollar los conocimientos y los fundamen de base para imponer un desarrollo sostenible de estos recursos zoogenéticos, este tema será tratado en el artículo. Una descripción más detallada de este dispositivo se puede consult en Wooliams J.A. et al. 2005. Sustainable Management of Animal Genetic Resources. Nordic Gene Bank Farm Animals ISBN 92-893 1089-8.
