Systems (physical and human) - How do humans and the physical environment interact? Can they ever do it successfully?
Processes, patterns and trends - How are amazing places formed, located and impacted?
Orientation in Space and Time - What areas need thoughtful management and why? How are these areas formed throughout time and place?
To understand systems you need to understand the processes that cause change over time (trends) and variations over space (patterns).
