Biological Oxygen Demand


Last lecture…
BOD: The amount of oxygen that
would be consumed if all the
organics in a volume of water were
oxidized by bacteria and protozoa
Clean water is very low, raw sewage
is very high
If BOD is high, no dissolved O2
remains for higher life forms
Von Thünen Model
Yield
Transportation rate
(e.g. $/ton-km)
yield
Distance of
parcel from
market
LR = E (p – a) – E (f*k)
Price received
(gross revenue)
Location-specific production costs
Yield-specific gross
revenue potential
without spatial
effects
The role of geographic
location in adding to total
production costs and reducing
revenues for given yield
Von Thünen Model
LR = E (p – a) – E (f*k)

Rent in The Isolated State



Highest and best use is determined
by the use that can pay the highest
rent
Bid rent
Let’s plot location rents for three
different land uses:
• Lettuce
• Corn
• Wheat
Relaxing
assumptions
Applying Von Thünen:
Land Use Zonation



Peri-urban model of Von Thunen
Intraurban model of land values
Continental scale zonation
