the most fundamental issue of our
time is the ecology the question that
me tah
and how to minimize as much as possible
our impact on the central planet
hinder our well-being and also
paradoxical that it may seem like
answer to me this is the city the city
dense paris london singapore moscow and
urban innovation
urban reinvention so why he
goes because the dense city
in fact that we feel that individuals so
it ultimately limits our
impact and our hold on the
ecosystems
then on top of that it does not spoil it
concentrate the brains and so has
priori the good ideas what also
extremely interesting with the cities
is that they grow to eight is
completely dizzying then she
already concentrates half of the population
world in 2050 it will be 70 % so that
maybe you can look like a
obvious to an obviousness because you
are French and we are already
80% urbanized but what is it?
means 70% urban in 2050
it means three billion people
who arrives in town in the space of
thirty years 3 billion people
hard to imagine what it can
represent but it’s as if they
had a city like strasbourg which
went out of the ground every day
30 years math teacher Strasbourg
after tomorrow strasbourg or equivalent
of a Paris metropolis that
would appear every month for 30
every few months I ‘d like
well explain to you today how
I arrived at this reflection and
how are we trying to
reinvent a little bit the urban of
way to gilles in paris there are four
years I decided to go traveling without
fly for six months in
train bus auto stop walk with that
I found I went through the few
kilometers that separates the Atlantic Ocean
of the sea of china
then after I bought a bike and I
surveyed Southeast Asia on bicycle
so suddenly on my way I found
some cities
paris moscou the year drummer beijing
hanoi chi minh sanh chau ngoc rangoon
singapore for the magnifying glass for and between
each of these cities enough spaces
surprising mountain rice fields
campaigns of the deserts of the steppes
huge spaces or services
amenities access to knowledge anyway
difficult to meet you and who suddenly
make cities the spaces where
concentrate opportunities we find
all in one place
the doctor the job the business the
religion culture and centers of
decision it’s swarming it builds his life
24 hours a day like here at chi minh
so I did not just walk around
also learned a lot and I remember
quite essential awareness that
I would like to share with you
today
the first is that cities
extend then it’s even some
thing that I lived physically when
it took me a whole day no
day out of the peripheries of
hotel chi minh
with my bicycle from the outskirts of
hanoi bangkok
it also happened to me to get out of
big paris so why cities
not extend because the
urban planning is a luxury I have
crossed cities or bits of
city like here in india where there the
cadastre does not exist round where you
hives the electricity networks the
water networks housing units
build completely
wild or free it depends a little on the
point of view there is no baron
haussmann who have been there all
fate of earth
so obviously there are some
negative consequences 1 for example the
creating danger zones because we
did not think about why
were we building there how
did we have to build
I let you imagine these cables
electric there in time we are pretty
the beginning of the monsoon
we can have water until there is
also positive consequences by
example the fact that we develop the
inhabitants develops services that
exactly match their needs
because it’s them who develop them
it is for them that develop them a
appropriation also that is very strong
an empowerment I have to charge
what surrounds me what does it look like
second realization is that
Western cities are cities
old is also the thing that
surprised me the most when I am
returned to France I put a little
time to understand what it was but
in fact our cities are filled with
the elderly
so how did I realize in
made by contrast because I lived
for over a year in cities that
were filled with young people
so what does it involve his pass
to obviously involves building
cities that are with amenities
specific for this population
and then it puts a little question in question
still our ability to conceive the
city of tomorrow that will probably be
rather invent in Africa or Asia
so I did not just watch this trip
also allowed me to make
convictions to forge beliefs
extremely strong on on the urban the
first conviction that I wrought
I think you start to understand
it’s that density is a good thing
so obviously I do not minimize all
across a dense city the
pollution the noise the dust but
finally it’s probably the city
time it’s probably the only
solution we have
to limit our hold on the
ecosystems 10 billion people to
to feed dress up to lodge it makes a
sacred land holdings caen you there
think it’s pure calculation
the pavilion of 300 square meters
for each family it seems
hardly sustainable just to get
to stay ok the density is a good thing
but what density
for me what he does city is the
activity density is not the density of
concrete I know no better example
gaps and pitau the new capital
Burmese
it’s a pretty impressive city
she’s done six times washed the size of new
york
impressive infrastructure
it’s because you find on the
photo is for example ways of
traffic that make up to who
allow to align up to 20 files of
vehicles imagine yet on these
traffic lanes it is possible to
see a cart pulled by a donkey
face the void just the opposite of
rangoun vibrant activity or even
this little village of the lake inle in the
campaigns on a market day
we can see canoe traffic jams
out of the loop me that makes me say that in
does what makes the city since
always what makes the interest the
power and wealth of a city
that economic exchanges
it’s the diversity of services that’s the
mesh is the social bond density
it’s the cultural exchange and it’s the
easy to navigate from one to the other
second very strong belief is that
the most dynamic areas
it is the areas that have appropriated
the inhabitants ie the areas on
which the inhabitants feel good
feel comfortable then that why
is it important
well because it’s a prerequisite if
we want a dense city because who says
dense city ten small habitats said
need need to live a party
part of his life outside of home
self is what explains in
part that paris is such a dense city
so interesting so vibrant and it’s
so what we find is what we
feels a lot in beijing
and it’s a real pleasure to see
like here a martial art competition
in a park fun to participate in a
water calligraphy contest on a
pavement
or pleasure to participate to interfere
in a morning gym class in the morning
in the street what does that mean
it’s going to mean it means you have to
that we create public spaces in
which people feel comfortable in
security lacking the most
possible constraints such as
public spaces whether they be
lungs can walk maybe without
cars that come block the flow
exchange hindered the activity of an edge
to the other
a bit like what we saw this weekend
with car-free bets that’s all that
makes me say that there is still
a lot of things to invent for the
times create denser cities for
limiting our impact is more enjoyable
because we still have to make them
attractive but also to
center the inhabitants in the center beyond the
decision-making process and of and of
design ultimately because these are
them by their activities their ideas their
appropriation of space that make the
city and that’s what we do at
paris by urban experimentation
so what is it
urban experimentation is the fact
to position on urban space at the
thank you for passing a product or
a service that offers in any case on
the paper an improvement of the city
and then eva evaluated him especially evaluate
if it works I offer you some
the and some examples it’s always
more talk let’s start with the rubbish
gold that says concentration of individuals says
necessarily concentration of waste
how are we doing to treat
always more waste if possible in
reducing the number of trucks as long as
can we start already with the
organic waste your leftover meal
unsold food food waste
plants
in fact it’s a gold mine why
because by anaerobic digestion can
produce energy with and then by
composting but we can create compost
quite rich
he uses it for something else
taking composting is enough
interesting because it allows us to
treat the waste locally
last year we thought we
was going to test a composting system
electromechanical which on paper we
propose to reduce the time enormously
composting to reduce nuisance
practically without any consumption
electric
in short a little the holy grail said good
well we’ll see what that gives so we have
positioned we left with a start
up who’s called the Alchemists and we have
positioned their their proposal of
electromechanical compostors at large
neighbor in the 14th arrondissement for
see what it was like then what is it
that it gave
banjo already that allowed us to compost
to treat 7 tons of bio – waste
so it looks small 1 but it’s
always it’s taken for the community
case not had to do it
and then the clean of experimentation
it is to test on a small scale
what is interesting is that we have
observed as planned on the
paper no nuisance very little of
olfactory nuisance no arrivals from
rodents electrical consumption in
rather weak effect what is
interesting also is when we have
same product five cubic meters of
compost compost that could be sold
because he has passed all the approvals
sanitary through experimentation for
to be sold which allows for
think completely differently
the economic model of this type of
solutions and then what does not spoil anything
is that all the currency flows
whether it’s garbage collection or
diffusion distribution of compost
were made by scooter
let’s take another example
this car park surrounded by vertical towers
his aubervilliers so that’s the parking
a home of young workers who
also canteen for just about any
neighborhood employees
so here he had some problems of
safety for pedestrians is also a
big effect of urban heat islands
what does it mean the effect
of urban heat island that means
that when it’s hot here it’s very
very hot
so it’s true here huh it’s true
in many places paris for everything
tell you weather france can measure
up to 8 degrees difference in time
hot weather
between Paris and less
urbanized around 8 degrees so the
tenants of the site are told that it
was enough to have 45 degrees in the gold
in their offices
summer and then it was necessary to redevelop
completely rethink the space to
to make a pedestrian zone but not
no matter how
they partnered with the firm
of architects who offered them that for
to structure a rather original approach
which allows to combine both the
benefits of the forest for example the
refreshment or shade age brings
naturally by the trees and
benefits of the city accessibility the
possibility of making multi uses
have taken any project under this prism
they have for example try to answer
was always trying to answer the
question can we make a coating that
absorb rainwater and who
restores in warm weather
a bit like if we sweat what we
would have the benefits of a
natural balance and the benefits of a soil
hard then we decided to do
a pilot area on the island effect of
heat for example with a partnership
with weather france the Parisian arrangement of the
climate and PhDs we set up
a temperature tracking system
before during and after the transformation
of the site to see what it gave
and the goal here is to show that
the layout can have an impact
positive about the city climate and
understand how to do it
third example to show you a
little diversity of projects
accompany that it answers the question
that I was just now finding
that I posed just now on the
population the elderly population in the city
so how does one improve the
quality of life of this population is
at the same time break their isolation so
many many suffer city launches
moment we are testing in the
xiii rounding a solution of
neighborhood conciergerie who developed
specific services and animations
for this elderly population
and on top of that she set up some
z and gestures of the processes of
awareness raising to accompany these
especially people in the periods a
uncomplicated like a big cold or
a heat wave
so here our goal is to show
that the city how is that the city
can become more inclusive avoid
that they forget people is oblivion
someone forgive in his in his
development
now I showed you all these
examples how are we going
calculate how are we going to follow
how are we going to conclude that a
experimentation learned to walk not
in a good way then we look at
five things primarily the first
and this is the most important it is
appropriation by users
users it can be tourists the
elderly people the
students the workers who goes through
there appropriation means that
it’s these users have tested this
they were offered what are
appropriate the valid
maybe even have already diverted it from
its initial use and tell us enough
top I ‘d like to have that in my
district
everywhere to say that it works it’s up to
to say also that also means that the
the impacts that are measured the impacts
positive to its superior to the impacts
negative
of course but not always good of
to say it then impacts it can be
on the environment about inclusion on
resilience on quality of life say
that it works it means that it is
feasible
it means that the efforts that are
necessary and the complexity of implementation
work and pretty much
proportional to the benefits
remove a big that’s worth saying
that it works is also to say that it is
sustainable that is to say that it is
reproducible that we know we understood
that there was a development model
and that in addition to that we perceive that
when we are going to change scale a priori
we do not pay the profits finally say
that it works
that is to say that we gave ourselves the right to
to be wrong is to say that we took the
risk that it does not work and that
stage it’s not serious it’s even rather
beneficial because we understood why
it did not work and where it blocked
will conclude anyway I wanted
go back to my initial question actually
all these solutions that we accompany
me she allow me today
to be optimistic about being deeply
optimistic about our ability to live
more numerous and better in town whatever
be our profile and so reduce our
grip on other ecosystems
so why cities in this sense
is the best place to live because
that finally it’s the only solution
that allows us to take care is to
save what’s around us
because they are centers
opportunities and because we have all the
ingredients anyway I see him
every day to make them centers
of well-being and today it does not hold
more than us to assume and embrace
this nice density thank you
[Applause]
time is the ecology the question that
me tah
and how to minimize as much as possible
