Block 01 Management of urban infrastructure
1.Key Challenges
Demographic
Rapid rate of population growth / infrastructure lagging behind
managing the current large population
Risk of extension of slums
Socio/Economic
increase in socio/economic gap
Gender sensitive policies
affordable housing for different groups
Safe drinking water
adequate mobility
Waste (solid, water) management
clean reliable energy
Technological
retrofitting a city can cost 3,4x compared to a well planned
aging urban infrastructure
inter dependencies of each function/ holistic approach
Environmental
Climate change (sandy storm)
providing greener solutions
Financial
last to look at
more and better with limited funds
Prioritizing the needs (transport / electricity etc)
making sustainable income
2.The main urban infrastructure systems :
Transport
Tracks
things on the tracks
Mode to mode connectors (stations)
Housing and green
Housing
-Houses
-Industrial
-Gated community
Green
-Urban forest
-Biological gardens
-urban vegetalization
Energy
electricity/ gas/ etc
Household and industrial consumers
backups (hospitals etc)
water and waste water
abstracted from river basin
treatment and distribution
waste water treatment ans discharge
waste
consumption > waste > collection > treatement
energy production
communications
physical and wireless
The main dimensions of urban infrastructure
Technical
Lines and nodes
consumed by the customer <Service Layer <-Physical Intrastructure Layer
economic
Base on technical dimention
sunk cost (money cannot be recouped)
Economies of Scale
Market powers (because of this setup)
jurusdictional
When the technical dimension is used among many cities
-interoperable
-legal system
-management
social
negative - equity exclusion
positive - equity inclusion
environmental
Positive - clean energy / green
negative - emissions, noise, pollution
Urban System :
Primary infrastructure (lec 2)
Deliverable
-Sustainability
-Resilience
-Effciency (
eg transport
)
Secondary infrastructure
-health/ education etc (not discussed in this)
As a city we should be able to
-quality of life
-attractiveness to the city
-competitiveness of the city
Analytical perspective
Public policy perspective
The goal is to provide public services in terms of..
-accessibility
-quality
-affordability
-equity
if the services cannot be self financing, subsidies will be paid
Aim is to maximize public services (within financial limits)
Mainly done under political steering (ownership) or via contract
Public Economy perspective (> 1980)
Mainly profit is considered (at least cost recovery)
sibsidies only in case of market failiures
Maximizing economic growth
steered via
Competition
Unbundling (separation of infrastructure from services)
and also regulation
