Current news stories are a great place to get information on what solutions different individuals and groups are offering. Consider searching your issue and adding the term: propos*. That tells the database to bring back any version of that word from that point on (e.g., propose, proposed, proposal, etc).
You also might want to search the policy statements of issue groups that are organized around your topic, or of political parties.
These resources provide overview to current topics of social and political interest. Pay careful attention to whether the information you're using is part of factual overview or the persuasive argument.
