Sustainable Cities
City Planning Part 2
LO. We are building a 3-D model of our
2-D Design
Food
 To meet the need of our rising population, it is estimated that food production will need to increase by up to 70%
 Due to the increase in transport costs will increase, so how can we grow food closer to our cities?
 We will need to think carefully about any waste we produce. IS there a way we can grow enough food for
ourselves?
 Cities use up only 2% of the earths land
space, BUT they use 60-80% of the worlds
energy
 Our non-renewable energy sources are
running out, we have used two thirds of
them in 200 years.
 Non-renewable energy is finite. When its
gone it’s gone.
 By using this anergy at his rate we are
creating vast amounts of CO2, as well as
other harmful gases. This usage is directly
contributing to global warming, causing sea
levels to rise. Importantly for our ecosystems it is also having a disastrous effect
upon the lives of the animal and plant life.

Nature
• Due to the growth in population it means the
green spaces in our cities are being squeezed
out.
• This makes it difficult for animals to get safely
around our cities.
• The animals that pollinate our crops are under
threat, we need to ensure cities are places
where they can thrive. This will help keep our
food chains open.
• Did you know 40% of London is green space,
making it one of the greenest cities in the
world?
Waste
 As a population we throw away a
shocking amount of waste, globally
the total is 290 million tonnes of
rubbish every year. Most of this will
not just rot away.
 A lot of the waste we produce is
actually recyclable.
 We actually save energy by recycling
Transport
 Particularly in cities the car is becoming
an ever increasing problem, they
increase traffic congestion and where
do they all get parked??!
 People who travel into cities for work
are spending longer commuting. This
leads to problems including stress,
isolation and poor health through
obesity.
 Most cars need oil, which is turned into
petrol, to run. This finite resource also
creates smog and carbon monoxide
pollution which is contributing to
climate change.
