Translate the following English sentence to French:
"This makes it all the more important, in our view, for both the people concerned on the spot and local groups to be involved, as early as the preliminary planning stage, in decisions such as how projects are to be organised, so as to ensure that these projects - which of course we wish to fund - are sustainable from an ecological and social, but also cultural, point of view."
Il est donc d'autant plus important pour nous que la population concernée sur place ainsi que les groupes locaux soient associés dès le stade de la planification, de la définition des projets, afin de garantir une durabilité écologique, sociale mais aussi culturelle de ces projets que nous voulons financer.
