•In 1947, 17% of the country
could be called urban.
•1998 census reported that
32.5% of the country was
urban, which, according to
studies by the Planning
Commission, will grow to
nearly 50% by 2030.

opportunities of a low-
carbon future," UN

on, now we must act.―

INTRODUCTION• URBAN:
A continuously and contiguously
built up land mass of urban
development containing high
population density, labour market
and vast human features in
comparison to its surroundings.
Parameters vary from country to
country
– Population (5000-10000 Persons)
– Non Agricultural Activities (66%)6

INTRODUCTION• URBANIZATION:
Urbanization is the processby which large numbers ofpeople become permanentlyconcentrated in relativelysmall areas, forming cities.Internal rural to urbanmigration means that peoplemove from rural areas tourban areas. In this processthe number of people livingin cities increases compared
with the number of peopleliving in rural areas

ENVIRONMENTAL DEGRADATION• 40 per cent of reported deaths and 25-30 per cent of
hospital admissions ascribe to a single source, water-
borne disease.
• 11 million hectares of arable land, out of 3 million, is
suffering from problems of water logging and about
three million from salinity.
• Water Level upto700 feet in Lahore is considered unfit
for human consumption.
• 143 per cent increase in the number of motorcycles
and a 24 per cent increase in rickshaws over the last
decade.

ENVIRONMENTAL DEGRADATION
• Karachi is one of the most polluted (air and water) cities
of the world where total suspended particulates (TSP) is
three to four times higher than the level determined as
safe by WHO.
• Similar conditions prevail in other major cities like
Lahore, Faisalabad, Multan, Hyderabad, Rawalpindi, an
d Peshawar.
• In addition to this, tons of rubbish and filth burnt by the
sanitary workers of metropolitan corporations, in almost
every part of the cities, further worsen this situation.

DIFFERENT PERSPECTIVES
Economist Perspective
– Urbanization is an alarming trend need to be curtailed
through
• Creating balance in opportunities & rural
development
• Rationing of education expansion
• Expansion of labor intensive industry
• Reduce population growth
• Decentralized authority
Source (Economic Development Michael P. Todaro & Stephen. C . Smith)
14
DIFFERENT PERSPECTIVES Environmentalist Perspective
– Urban environmental problems are typically related to the
level of intensity of human activities – a function of
population density and activity type;
• Hydrosphere
• Biosphere
• Atmosphere
– Social & Economic problems are also associates with
urbanization include
• Poverty
• Crime
• Low Quality Housing
• Food Scarcity

DIFFERENT PERSPECTIVES Urban Planning Perspective
– Old School
• Megacities are not sustainable
• Curtail the size
• Divert the demand to new cities
• Integrated Rural Development (1960’s -80’s)
– New School
• Cities contain huge potential, must be capitalized
• New avenues of economic growth in services sector
• Technological advancement & innovations
• Economies of scale – Urban agglomeration
• Manage urbanization to benefithttp://www.fig.net/pub/figpub/pub48/figpub48.pdf

WHAT ARE THE REAL ISSUES?
17
LOSS OF AGRICULTURAL LAND AND OTHER GREEN SPACES
• Fertile agricultural land and
precious Green Spaces
should not be sacrificed for
unplanned and unauthorized
urban expansion.
• In rural areas 100 household
covers 100 kanal but in urban
it covers much less may be
20 kanal.

Productivity, by Rukhsana Javed, Farzana Shaukat, Iffat Jabeen
SOCIAL FABRIC – ANONYMITY, CRIME
• Part of the "charm" of living in a small ruralcommunity is that each neighbor is usuallywell aware of what the others are doing. Thedegree of anonymity most often associatedwith urban living is often absent in ruralcommunities
• Higher crime rates
• But - Urban is more egalitarian.
19http://www.uky.edu/~deberti/socsaea.htm
PER CAPITA CONSUMPTION OF FOOD, ENERGY AND DURABLE GOODS
• Globally, agriculture has met the
demands from this rapidly growing
urban population, including
food, energy and durable goods.
• It is attributed to higher income
levels and better living standards.

LOAD ON SERVICES
• In 2004, transport energy use amounted to 26% of total
world energy use and the transport sector was
responsible for about 23% of world energy-related GHG
emissions
• All urban services, social and municipal come under
stress
• Agreed but in rural areas cost of providing services is muchhigher.
• Lower per capita consumption of services also means
inequity in service delivery
• In urban areas, services are more optimally used

VISUAL POLLUTION
• Rapid pace of urbanizationcauses visual pollution inurban areas. Visual pollutiondisturbs the aesthetics bycreating negative changes inthe natural and builtenvironment. Billboards,open storage of trash, spacedebris, telephone towers,electric wires, buildings andautomobiles are forms ofvisual pollution.
28
HOUSING BACKLOG & FORMATION OF UNPLANNED SETTLEMENTS
• Housing stock deficit 2.4
million.
• 0.2 million annual addition in
deficit
• 50% of urban slums

WASTE DISPOSAL INCLUDING INDUSTRIAL & HOSPITAL WASTE
• Waste generation (percapita) is more in urbanand waste pattern isalso different (moreinorganic)
• Urban 0.55 Kg/cap/day
• Rural 0.45 Kg/cap/day
• Only in Lahore 5500tons of municipal waste

SOIL POLLUTION
• Faisalabad, Lahore,Kasur, Sheikhupura, &kala shah kaku – soil iscontaminated throughsalts & heavy metals
• 1810 cusecs municipals• sewage and toxic
industrial effluents arebeing thrown into riverby ten sewage drains andpumping stations

MODIFICATION OF MICROCLIMATE
33
The annual mean air
temperature of a city with one
million or more people can be
1.8 to 5.4°F (1 to 3°C) warmer
than its surroundings, and on a
clear, calm night, this
temperature difference can be
as much as 22°F (12°C). Even
smaller cities and towns will
produce heat islands, though
the effect often decreases as
city size decreases.

UNEMPLOYMENT, CRIME & POVERTY• By 2029 over 60% of world population
will live in urban cities. Urbanemployment is already in disastercaused by tough competition due toexcessive supply to limited buyingpower would lead to massiveunemployment.
• Urban issue but employmentgeneration induces urbanization
• Punjab witnesses 10.2% increase incrime ratio
• The crime against person andproperty, shows upward trend with theaverage of 24.12%
• General trend regarding crime is morein urban than rural

BENEFITS OF URBANIZATION• Cities are engines of growth
• Proximity and Concentration – Compact Development
• Business like organization of municipality
• Small scale monitoring of livability
• Employment Generation
• Preservation of rural area
• Better living conditions
• Enhanced service delivery e.g Vaccination rate
• Better access to services
• Opportunity for concentrated political movement
• Diffusion of innovation

INSTITUTIONAL RESPONSE
• National Housing Policy 2001
• No provincial housing policy
• Housing, Urban Development and Public Health
Engineering Department
• Local Government & Rural Development Department
• Devolution Plan 2001
• Environment Protection Department (BS 17 & 16)
• Transport Department (26 MVEs, checked 386360 in last
year)
37
RECOMMENDATIONS• Shifting of industries outside the urban areas and
outsourcing of emission testing,.
• Regulation of prequalification of
architects, Beautification competition
• Community cost sharing model for improved sanitation.
• Full cost recovery, Resource generation through
recycling of municipal services.
• Alternate plans for achieving objectives. WASA Lahore
spends 450 million/annum on storm water. Sufficient for
1000 invert wells. .
• Revenue generation from waste auction, RDF, or Waste
to Energy
38
RECOMMENDATIONS
• Buy back the underutilized areas and
capitalize the potential
• Heavy taxation on vacant plot. Housing
policy to cater for mandatory high rise
portion, infilling of existing approved areas
• Explore PPP options for mass transit,
Revision of rates of parking etc
