[The Grammarian]

Urban planning and geographic information systems aren’t exactly “fluff” fields, even if environmental sciences sounds like a garbage degree.

[muawiyah]

Urban Planning, as in "Planning", is just another branch of Architecture.

That, BTW, is a complete set of knowledge, just like engineering, or arts & sciences.

"Environmental Management", as it is euphemistically known, has a place in Planning.

Nothing like a town that has no plans in place to deal with garbage, trash and abandoned cars and industrial sites.
