Vanessa,
There is an excellent albeit academic review of all of these terminologies – Landscape Urbanism, Green Urbanism, New Urbanism, TOD etc etc – in a paper in Landscape Journal written by Richard Weller in 2008. It is called “Landscape (sub)urbanism in Theory: Towards a theory and practice of landscape architecture in regard to the contemporary suburban condition” .
Other references for Landscape Urbanism include the AA Landscape Urbanism book (now fairly old and rather forgettable), Center: On Landscape Urbanism by University of Texas at Austin and Kerb 15: Landscape Urbanism.
Other good references are detailed in Richard Wellers paper which is as exhaustive of a review / summary as ive seen.
