Awaji Shima Region

• 600 km²
• 150,000 inhabitants
• Larger spatial scales
• Hyogo ken
• Kinki region
• Japan
• East Asia
• Eurasia
• World
• Smaller spatial scales
• Municipalities (gun)
• Settlement area (cho)
• village (machi)
• Places
• Private units

5
Relation local, regional, global

• Region is characterized
• By smaller local units
• By larger global unit
• Regional (local, global) state
• (infa-) structure within the region
• Regional (local, global) use
• Economy
• Ecology
• Quality of life

6
Long-, medium-, short- term processes

• Processunderstanding of Landscape
• Long term gt 100 years steps of change
• Medium term lt 100 years, gt 1 year changes
• Short term lt 1 year processes

7
Long term processes

• Long term processes
• Geology
• Climate
• Soil
• Water System
• Vegetation
• Animal Life

8
Medium term processes

• Political administration (cho, machi, sanchome)
• Demographic trends
• Land use
• Agriculture
• Tourism
• Roads and trafic infrastructures
• Settlement areas

9
Short term processes

• Energy use
• Greenhouse gases
• Water use
• Waste generation
• Human inputs in agriculture
• Working hours in agriculture

10
Landscape Time

• Landscape is dynamic
• Arena for all processes
• Landscape changes continously
• State and Use
• Longer processes generate the state (Structure
  Infrastructure) for the use in shorter
  processes
• What is state and what is use depends on our
  interest
• Human Understanding of Landscape Processes
• Long term processes are perceived as stable/non
  dynamic
• Medium term processes depend on long term
  processes, generate (infra-) structure for human
  beings
• Short term processes describe human actions
  within a year

11
Anticipated Processes Cyclic

• Cyclic means that the pattern of change is known
  and repeated on regular base (can be anticipated)
• Decades harvesting of trees, perhaps climate
  variations, appearance of Feb. 29th
• Years harvesting of field fruits
• Seasons spring, summer, autumn, winter
• Month salaries
• Week weekdays, weekend
• Day morning, noon, afternoon, evening, night

12
Anticipated Processes Non Cyclic

• Non-cyclic where the pattern of change is known
  Growth and Decline
• Centuries waves of earthquakes and vulcanos
• Decades
• perhaps human induced climate change,
• life periods such as childhood, youth, young
  adult, family start, family peak, career peak,
  agil pensionist, pensionist,
• plant growth states of higher plants,
  availability of resources
• Years Investments and loans,
• Seasons extreme (summer) heat, extreme (autumn)
  thyphoons, extreme snow (winter) or floodings
  etc.
• Month amount of salaries
• Week visitors of touristic spots on weekdays,
  weekend
• Day the menue in ALPHA cantine

13
Non Anticipated Processes Surprises regarding
Natural System

• Not experienced before
• Not included in planning management
• Climate change
• Impacts of climate changes
• Directions of climate changes
• Acid deposition, forest die-back, fish dying
• Chemical time bombs
• Colloid chemical compounds and pH change
• Manipulated genes?

14
Non Anticipated Processes Surprises regarding
Social System

• Rural depopulation
• Population decrease in developed world
• Aged population, perhaps break down of social
  system
• New power of kids as consumers
• Several old people to support one kid in
  shrinking societies

15
Planning and Management

• Is like riding a bicycle
• Foreseen cyclic processes of wheels
• Unforeseen but expected disturbances when passing
  hinders
• Surprises are a jump into the water
• Planning and management in a changed context
• The road beneath does no longer exist
• Learn how to fly or
• Learn to swim
