where clause

I was doing my translation homework which talks about the natural resources in Africa. With the driest Sahara, the Nile and the Congo are there too but where it is too moisture. And I encountered a sentence like this: "Everything is there but nothing seems to be where it could possibly but of any use to anyone."

I understand what the sentence is trying to say, but totally get lost with the where clause. Should I say "Everything is there. However, nothing seems to be of any use to anyone, though it should be."? How can I analyze the sentence? What is the where clause for? Thank you so much!
