O que “não” sabemos sobre a sustentabilidade das cidades | Sara Moreno Pires | TEDxAveiro


[Music]
I hope you are comfortable
I’m not in the next two minutes.
at least talk about what we know and do not
we know about the sustainability of
cities and why this is important
I have been studying for some time now
and try to understand the trajectories
unsustainable development of the
current societies and my basic training
the economy walks away from the pt not realize
the importance of reducing and evaluating
carried out by korea is through
indicators but often associated with
indicators only numbers and what
my training and combines a was the
enthusiastic way of looking at the
numbers far beyond vision
objective and particularly the fact that
We want to give it to you only later.
that the indicators can give us a
a far more extraordinary vision than
a monocode view of the numbers in the
allow us to awaken the consciences of
indicators make it possible to make
and visible is that what is abstract is
difficult to understand how
sustainability and nothing more abstract
that the air
we could think that the plane had
up to the 17th century an act symbolized
nothing is there to die scientifically
proven otherwise
we did not know that the article in weight today
we know that air has weight and today we see
that the act is a very
different in and out of the cities
today we see in real time using the
against concentrations of pollutants
the boys and we evaluated how much air
causes respiratory diseases
how to kill the indicators have this
ability to make us understand a whole
make us interconnect the most
more than this to do is use the
our own challenge our own
perception of the world and reality and
confesses that this is exactly what
happened with only one indicator and there are
nine years ago I work with
for more than 18 years and tries to
use the indicators to use
gate – for more sustainable futures
but I was surprised by a
only about nine years ago that it did not
I change my world pretension
I bring this indicator here to expire
this very simple graphic is published
in 2009 by the team of scientists
led by rockstrom and
traffic a simple showed yesterday second
planet Earth
the last 100 thousand years of planet earth
and incredible temperature oscillation
average of the planet earth along these
one hundred thousand years surprised if we eat pantai
how was mussum possible and in the last
eight to ten thousand years the planet
planet earth temperature stabilized
Stabilized is levels continuously
friendly to us humans
I had thought the smallest since
peaks we want someone sticks month we
We will have here to talk about traffic and
was this stabilization allowed us to
discovering agriculture allowed us
develop in how many civilizations until
to this day
and this is the only trio in earth life
which has ensured this development and
this triumph of earth life the
scientists called alkyne
the drama and look at this image think
that she passed
she just does not represent presents already
we’re not over use so we do not
we are in the era of logic 950 of nod
years over here man began a crusade
that has left us
logic and into another age of
anthropocene this was an area full of
Of course, I doubt many questions.
on the future of humanity on the planet
land not the future of the planet earth
future of humanity on the planet
So what have we done in 1950 years to
or more specifically here 60 years to
where to explore our impact more
on the planet earth in a way
traumatic
most of this option should be
growth of the world ‘s population
we tripled the world population
in little more than 60 years and concentrated
especially this population taught
today we have seen that the urban population in
global terms is more limited than the
the total population estimates that by 2050
two-thirds of the world’s fifa population
cities are today the center of
problems but mostly center of
solutions for our future and in
cities that we have created the great part
the wealth of the world in the cities we
we have created more than 70% of the world’s wealth
but also in this Christmas we have the
greater social inequalities
it is in the cities that we consume great
part of the energy that is produced at
60% in energy is consumed in the
China and more than 70% of global
of greenhouse gases is produced
due to the activities that occur in the
cities and greenhouse gas emissions
greenhouse gases are the major
responsible
climate change and above all
for this new age of the anthropocene in which
We are now in the city ​​for all that.
that we consume generate 30% more
waste produced throughout the world and
We feel that we have the
still does not show signs of a future
much of the future of planet earth
And you ask me what we see.
about Portuguese cities
we even know about our
to find indicators that will help us
let us know the past the present and
especially the future of our cities
if you ask when they could
find this information when
tried to find indicators that we
enable us to know more about our
cities
would probably say that what the
our national statistics institute
it’s an unofficial statistics
but they would probably have
some difficulty in achieving
find the entry or possibly the
out the statistics of china in
Portugal
also consult platforms such as
by date much more interactive easy
view of comparing information from
to discuss statistical information and
where even children are entitled
first test each and used to change
their knowledge to change their
actions in my statistical perspective
but we continue to have a
to present monocortical diversity with
much more
It is very very complete and with much more
to know about them
and therefore why not
universities when there is great
part of the scientific knowledge a
much of the information is being
worked in the context of universities
but we’ll probably have to open
many gazettes we will have many of them
only this powder some with indicators
interesting about the cities but
we will have much trouble connecting
all the information and, above all,
difficulty is that this information is
us citizens and is our senate
the next step would really be
consult why the effects of our
municipalities are the entities that best
know the territory of more information
have more general information about
cities
they think they could find
information on the websites of our
counties
my perception is that there am not her
closed’re hit saints is as sexed
it is scattered as it is not
systematized it is not visible to
we citizens and we citizens will not be
also responsible for a large part of the
growth of our cities and our
projections of our
urban diligences we did not do
better than anyone
the cities and jmpla said that we are
the coal specialists we live in is so
difficult to make collective knowledge
so many individual persecutions are so
difficult to give a collective sense when
We do not even know our English anymore.
for this we have a smart cities function
the era of the great stadiums is
bicycles and new technologies that
they promised us release releases the data
at an impressive speed but
we are often much more dominated
by algorithms than we have the ability
to understand what he has saved and give us
that this information gives me and
I asked my question remains
we even know our dead are
he is able to reflect on it
Let’s give a simple example would be
curious to know which schools
are stressed in cities like us
men produce 10 times more
and are much more active in
promotion of energy in cities than
out of them would be surprised us
to say
that break us in terms of circulation
world with disappointment even though we each
of Portuguese we would need 2.3
planets to keep our
divine style and much of our
ecological footprint is due to what
we got in the cities
This is because of food consumption.
can we think that feeding
of the finals is one of the great challenges
environmental and health issues we have
front
My perspective is that it does not
we can transform what does not
we know and we also have a great
front we can do very different
We can do very different things through
official statistics
we must not lose sight of democratizing the
role of universities in broadcasting
knowledge to undermine the role of
municipalities and all of us together to
make the indicators move the
our consciences
we have many examples of how this is
possible in many cities that already
many different
we have examples such as cities
ConCidades pollution in Europe more
of 20 years harvesting work
contaminated indicators and therefore
became the green capital of europe in
2015
We have cities in the state to carry.
such as the trade union movement and
community emerged in the 1990s in
cities like vancouver enipec
mobilize society build visions
finishing with cities based on
indicators and we also have examples
Australian cities such as Melbourne or
in the United States it is
national politics that put us in the
indicators of how we can
use them to change and transform
our cities is my final message is
especially for us to use and look at
the indicators in a much more
We will use the indicators to
awaken our consciences to
understand that the challenges we face
the front are too large for
discuss and communicate this information
a constructive way and to realize
that reality is about our future
is also determined for the future of the
planet
we will use the indicators for the
mobilize to improve our
behaviors that
everything so that through the construction of
sustainable cities
continue the journey in time the planet
Earth
thank you
