Translate the following English sentence to French:
"That is why, where the good LEADER projects are concerned, we need to ensure that those which have proved to be outstanding are not suddenly discontinued; instead the ideas which have proved to be worthwhile need at some stage to be transferred into the standard programmes as a reliable, positive component of our support to rural areas."
Pour les projets Leader de qualité, nous devons dès lors veiller à ce que l' on ne puisse pas subitement couper court aux idées qui ont fait la preuve de leur efficacité, mais que celles-ci soient au contraire inclues dans les programmes normaux comme parties intégrantes et garanties de l' aide destinée à l' espace rural.
