For instance, my field is Information Technology and I would like to know if it is okay to submit to management and environmental science publication. Of course, it's not purely I.T. but this is a paper on how I.T. can help preserve the environment, specifically on reducing consumption of resources.
What are your thoughts on this?
There isn't anything wrong with submitting to a conference that might not be a perfect fit. I would urge you to ensure that the fit is decent enough that you won't be wasting anyone's time, but cross-polination can be great for both fields.
When I was a graduate student and was helping my advisor review papers for a prominent conference, I read an outstanding paper that I didn't believe was on-topic for the conference, and I suggested to my advisor that it should be rejected it even though it had a novel (and cool) contribution. When I discussed it with her, she said that for really excellent papers, program committees will sometimes be flexible. If I was convinced it was that good, she said, I should give it a positive review and let the committee sort it out. In the end they accepted the paper. It was very well-received at the conference, and the authors were excited to get the paper into the competitive conference, where it would undoubtedly be seen by a lot of people.
I think if your work is either interdisciplinary (i.e. has impact in two different fields), or at the border of two fields (e.g., physical chemistry or molecular biology), you should publish in journals and conferences in a way to address both communities. We usually have a lot to learn by outsiders coming into a given field of research, as they bring a new view, new ideas, concepts and methods. Your case sounds exactly like that, so I'd say go ahead!
