"They" refers to "solutions." You are quite right to ask the question, since the sentence is poorly written. In proper style, pronouns should refer to the immediate antecedent, that is, to the last noun mentioned before the pronoun. In this case, that would be "challenges." However, from the context, I would judge that the author is most likely trying to refer to the word "solutions."

Probably "solutions".
