Thanks Jildau, that is clear!

Wow, this is a complicated sentence, even for a native Dutch speaker. Sounds very much like a policy maker that doesn't know exactly what he/she wants to say, so just wrote some important sounding words together. If you like this type of stuff, read these columns: https://www.nrc.nl/dossier/column-japke-d-bouma/ She writes about this kind of "vaagtaal". To answer your question: "aan" is together with "biedt", but not as in "aanbieden", but rather in "ruimte bieden aan", which means making room for/accommodate. "Aandacht vragen voor" is also a combination of words that is often used. That means: raise awareness for. I guess "aandacht vragen aan" is more directed to a person. Ik vraag aandacht aan mijn man. But it would be more suitable to say: ik vraag aandacht van mijn man. "aandacht vragen voor" is more directed to a subject. Ik vraag aandacht voor het milieu. I hope this helps. :-)
