21st Century: Planning of Rapidly Urbanizing Cities and Urban Transitions
New urbanization projections (prepared for Rethinking Cities, World Bank, 2014):
• CHALLENGE: 10B urban people? 87% urban planet? 21st century = 3x more urban residents in
‘less developed’ world? What will be the infrastructures/institutions of a healthy urban planet?
• OPPORTUNITY: “Urban population will be split unevenly, with just 1.2B living in cities of what
we now think of as developed countries and 8.6B in cities of the developing world.”

TARGETS
•
•
•
Equity: access for all to adequate, safe affordable
housing & basic services and upgrade slums
Transportation: Provide access to safe,
affordable, accessible & sustainable transport
systems for all, improving road safety, expanding
public transport, with attention to special needs
Enhance inclusive and SUSTAINABLE
URBANIZATION, capacity for participatory,
integrated, sustainable planning/management
HEALTH & DISASTERS: Significantly reduce
deaths, # of people affected & direct economic
losses caused by disasters, with focus on
protecting the poor & vulnerable populations
AND HEALTHY !?!
FACTS AND FIGURES

•
•
•
Half of humanity – 3.5 billion people – lives in cities today
By 2030, almost 60 per cent of the world’s population will live in urban areas
95 per cent of urban expansion in the next decades will take place in developing world
Cities occupy just 3% of Earth’s land, account 60-80% of energy consumption; 75%of carbon emissions
Rapid urbanization pressure on water/food supplies, sewage, the living environment, and public health
High density of cities can bring efficiency gains /innovation while reducing resource/energy consumption
Discussion: What would your group agree are some
health benefits / risks with both provision and lack of
provisions of below urban infrastructures. Make a list.

Analysis of Mortality Data in Delhi, India
• More than 50% of Deaths
in Delhi – Causes Not
Classified
• Due to half of Delhi deaths
not reported by cause, both
bottom up survey and
community study are needed
to supplement hospital data
• 14% of total deaths were
of <5 children, 72%: ages 5
to 69; 15% of those > age 70

Areas of Highest Perceived Risks and Interest for
Infrastructure & Policy Interventions in Mumbai
Priorities for Action and Policy
• Quantitative + Qualitative Methods for Analyses of
Urban Emissions, Risk & Vulnerability across cities:
food-energy-water resources and infrastructure & supplychain interdependencies, hazard-related health outcomes,
exposure, sensitivity and capacity of populations
• Institutional capacity to govern urbanization, climate,
FEW resources & their nexus: Potential for replication of
methods across cities globally to examine: sustainable
infrastructures; policies; interplay of actors and networks;
institutional enablers/barriers of effective actions
• Understanding Urbanization Alternatives and
Implications for Society-Relevant Outcomes & SDGs
• Energy & Governance Chapters for 2nd Assessment
