I'm reading an article on the web, which has the following sentence:
Ces constats tragiques faits, corrélés à des analyses que réalisent d’autres associations sur le terrain depuis longtemps, Michael Hobbes a interviewé de nombreux experts.
My attempt at understanding this sentence: I suspect that there is a subject/verb inversion around the "que". If I were to undo the inversion, I would rewrite that part of the sentence like this:
corrélés à des analyses que des autres associations réalisent sur le terrain depuis longtemps
My best guess at the whole sentence's meaning does not make much sense:
These tragic reports make [??], correlated by some analyses that some other associations carry out [present tense??] about this topic for a long time, Michael Hobbies interviewed some experts.
I don't understand "C'est constats tragiques fait". "These tragic reports make... [what do they make?? it isn't stated!]"
1. What does this sentence mean?
2. Is my inversion correct, including my choice of "des" as the article that precedes "autres associations"?
3. In the original sentence, what is the d' for? I would have expected an article like "les" or "des" instead, but not " d' "
4. Why is réalisent in the present tense? It sounds like it should be in the past tense. ("..that some associations have been carrying out for a long time..")
