Cities face challenges from rapid urbanization including demands for resources that outpace supply. Sustainable cities aim to improve infrastructure to be more environmentally friendly and improve quality of life while cutting costs. Key aspects of sustainable cities include good governance at the metropolitan level to address local issues, as well as green technologies, public transport, energy and water management. While national policies can provide strategic direction, local leadership is also crucial for sustainable urban development.

3. FAST FACTS
37.7 crores or 31.16 percent of India lives in urban centres.i
30 people leave rural areas for urban areas every minute.ii
70 percent of new jobs would be generated in cities by 2030.iii
49.7 crores to be added to the urban population by 2050.iv
SOME CHALLENGES
Urbanization is seen as being anti-rural by a section of the policy makers.
According to a McKinsey report, India’s Urban Awakening: Building
Inclusive Cities,
Sustaining Economic Growth, India requires USD 1,20,000 crores in capital
investment to
meet the demands of the new cities.
More than 50 percent of India’s population is below 25 years of age and
about 18 crore
young people will enter India’s workforce over the next two decades. India
needs dynamic
cities to cater to the young population’s employment demands.vi
The Planning Commission has also acknowledged that the rapid
urbanization poses a
managerial and policy challenge. The demand for basic necessities like water,
transport,
sewage treatment will greatly outmatch the supply.

5. The strategy behind this project is to accelerate the creation of an actual
floating city while making
seasteading – pioneering the oceans and creating new societies –
accessible to the average
person.
Economic Opportunities –
As Earth’s final frontier, the ocean offers radical possibilities for some of
our boldest
economic dreams. From harnessing the immense stores of energy and
nutrients, to serving the global demand for
financial, medical, and human services, seasteading will give rise to
many 21st century fortunes. International
waters offer a more friendly regulatory environment, and allow for
worldwide recruitment of entrepreneurs,
investment capital, and top talent. The oceans are already the
superhighway of trade – seastead real estate will
be optimally located to tap into the bloodlines of a globalized planet

6. What is at the heart of a sustainable city?
If you look at this ranking, which considers
Vancouver, San Francisco, Oslo, Curitiba, and
Copenhagen, as the most sustainable cities in the
world, it appears that lots of green technology is
key. Vancouver is heavy with renewable energy
including lots of hydropower and it has the lowest
per capita carbon footprint on the continent

7. Sustainable cities
Intelligent traffic solutions, green buildings, water management, and smart
grid infrastructure are just a few of the technologies helping to steer
today’s urbanization toward sustainability.The challenges presented by
sustainable urban development are immense. In 2010, 82 percent of
Americans lived in cities; by 2050 it will be 90 percent. Cities are
responsible for around two thirds of the energy used, 60 percent of all
water consumed and 70 percent of all greenhouse gases produced
worldwide. Sustainable cities are looking at ways to improve their
infrastructures to become more environmentally friendly, increase the
quality of life for their residents, and cut costs at the same time.

8. In general, data used for each regional Green City
Index are difficult to compare to other regions due to
differences in the way statistics are collected. Furthermore,
many specific indicators are different for each
Index, reflecting data availability and the specific environmental
challenges of each continent. Just two of
the quantitative indicators – water consumption and
water leakages – are measured across all regional
Green City Indexes. However, a number of indicators
have been collected at least in two to three regions. A
summary of indicators that were comparable across at
least two regions is presented on the following pages.

9. 1. Good governance and leadership at the metropolitan level National environmental
regulations can have far-reaching impacts, and are able to provide overall strategic
direction. Yet city-level leadership is just as crucial. Indeed, at their best, national
directives incentivise local governments to establish their own initiatives. For
example, the Mexican
government has a plan to replace more than 45 million incandescent
light bulbs with energy-saving bulbs by the end of 2012. In the US
state of Colorado, legislation requires that 30% of all electricity produced
should come from renewable sources by 2020. Germany has strong
national legislation too, covering many environmental issues including
building codes and water management. In addition, there are numerous
examples in all parts of the world where national, regional and local jurisdictions
follow common goals and set mutually re-enforcing standards.
However, the Green City Index series also demonstrates that the national
legislation needs to leave enough autonomy to cities to address their
most pressing issues and make their own investment decisions. Experts
across Asia, Latin America and Africa call for better leadership and governance
at the urban level. Although national governments are important
for setting direction, they can also have competing priorities or do
not always understand the nuances of local needs. There is a correlation
between good governance and top performance in the Indexes. The
leaders in the regions, such as Copenhagen, San Francisco or Curitiba all

10. Once upon a time, cities grew organically, naturally. They developed in
coastal areas, grew into hubs for trade and commerce, and served as
departure points for exploration. Slowly theyindustrialized, inviting
factories and businesses, blossoming from the added wealth of new
resources and new venues for spending. While those characteristics are the
fairy tale reality for some cities, others are hampered by rapid
industrialization that leads the way to uneven development, slums, and
inefficiency. In the developing world, cities have sprouted in places and
ways not conducive tosustainable growth and development. In contrast,
new proposals suggest harnessing a city’s potential for growth to increase
development, innovation, and entrepreneurship—and even address
humanitarian efforts at the same time
