Pensée unique concernant l’alimentation de demain ? | Philippe Cayot | TEDxAgroSupDijon


[Music]
good evening everyone
when I was asked when
hand- oriented organizers said to
talk about the breakup I told myself but
they are completely crazy about a subject
like that it’s huge and a topic about
agrifood is even more
difficult then quickly to break
it’s an idea a concept completely
new that will change your life that
can even disturb it deeply
can be a product it can be a
service app is a work a work
collective an artistic work
in any case it’s something that goes
to change permanently is definitely
another of life when for example
the computer the cellphone then
I could have talked about tons
examples of upcoming products in
agribusiness that could be
the opportunity to break
important in two lifestyles and I have
preferred to tackle the breakup under a
different angle
the break in terms of break in the
breaking
I explain myself and it’s a taste that I have
especially to advance against
current it is good sometimes to oppose
to some things that seem
inevitable and who does not suffer from any
debate and I will propose you to do
a debate on objects that seems
have no possibility of debate then
this idea came to me from a book that
was released very recently
it’s a book from sarah
shulman on the spirit gentryfication
of the unification of mind and who speaks in
make changes to new york
especially in the gay community with
inhabitants of a popular neighborhood
who were first dislodged from a
economic point of view but also everything
a very enterprising spirit very
innovative that was replaced by
much more conformist mentalities
and I asked myself the question is this
that the reforms we are told in
agribusiness in agronomy and
food are not they
object also of a form of
gentrification do not we forget
some basic concepts or part
of the population
so I’m going to rely on three things
which are announced changes and
probably little questionable the circuit
short agroecology and food
industrial that seems to be the worst of
things that can be offered to humanity
in terms of diet then I’m going
interest me first to start at
circus the courts then the circuits
short what is it to avoid that a
truck rides around Europe or
see around the world and that he
feeds a very large distribution circuit
long very expensive energy is spent
by much shorter circuits
so it seems like it allows a
gain prior to purchasing power to
consumers it seems that we are offering
increased income to the farmer he
would seem to be offering there that the
possibility of local job creation
and finally we will have a very impact
important on the environment
without questioning the validity of
a lot of concepts I will be interested in
particular on the last point that is
the environmental impact then I would have
could you take as an example by
example here suede with tomatoes
Swedish or strawberries and Décosse
I could have demonstrated to you using
scientific publications
it has been shown that he was more
interesting to bring tomatoes
from Spain than to produce tomatoes in
sweden or import strawberries from italy
then rather than consuming strawberries
Scottish you’ll tell me this is a
little caricature you take an example
very 7.30 rio ​​nal so suddenly I you
proposes to stay between the 48th north of
latitude and the forty seventh when
so that fits between reims and bonin
let’s see about two teeth and we’re going
start with austria and i will
stay on my tomatoes why because
it is a vegetable fruit that is
probably the favorite vegetable fruit at
world we have trouble to do without it
found everywhere and under all
forms
and I show you a first is then
that it is the result of a publication
very recent in 2014 here you have
in agronomic sustainable
development ‘ and we see that a circuit
very short 1 6 km from the area of
consumption in an ultra agriculture
modern greenhouses heated on a substrate
artificial we have an impact of
global warming by extinguishing
co2 which is far superior to tomatoes
imported from italy or spain
so actually if we look
actually organic farming
of a tomato produced in full summer in
about heating in austria we have
actually an environmental impact
in terms of warming capacity
climate is very low but look
well the Italian example it’s pretty
scoring if you look in blue in
blue is the packaging actually
the packaging of Italian tomatoes is
the one that brings the most impact
environmental but if you remove the
extraordinarily expensive packaging
and that you only compare the appearance
transport and the agricultural aspect you
see that the gap is not so
extraordinary and those despite
1600 km of travel by placing tomatoes
Italian so actually this analysis
it’s to show you what to do
very careful
the short circuit yes but it depends on
what of the mode of production it deposits
packaging if you make the circuit
short but you pack with
extremely expensive packaging if you
make a mode of cultivation that is not
actually attentive to the particular
energy expenditure are you going
find in short circuits that
is not at all interesting
so we will now take a
French example which is the diet
of cow for the production of milk
so this is an example that has been this
example it comes from colleagues
AgroParisTech published in 2009
this newspaper that the nine productions and
they demonstrated that and for the impact of
global warming in equivalent
co2 product and for the meaning of
rain in the equivalent of
sulfur feed cows for
produce milk with soybean imported from
Brazil has an environmental impact
less than soybean meal
lack of rapeseed cakes by no
imported product in France
so these two examples show you that
when we talk about short circuits
it’s not just about watching
transport that actually cost
energy
you have to look globally at
expenses is actually the
how you produce may have
considerable impacts in terms of
climate change the second
aspect of which I spoke to you is the
grid ecology agroecology is
something that is inevitable in
terms of public health in terms of
environmental health and yet there
still we can engage some debate
the vase the vision that some
policies have agro ecology and the
how it is transcribed in
the mainstream media is a way that me
seems highly questionable and which must be
bring back some important data
to understand that we can not do
any agroecology then the
first thing I’m going to show you
it’s still here is what
brought modern agriculture
she allowed in germany for example
if on this example that is one of
data from the iphone the food and
agriculture organization
it has doubled
wheat yields in germany in france
and in England
and if I show you this result it’s
to show you behind another fact
is that in the world we have not stopped
see and in percentage it’s curves
gray and in number of populations we did not
stopped seeing hunger decline in the
world and so we have to remember well
that agricultural performance is
first a tool to fight against hunger
in the world
this hunger in the world she is far
to be finished if you look at these
figures in africa
then certainly in percentage in gray
sees the proportion of population of
less and less in proportion
but in numbers we have more and more
people who are hungry and in Oceania the
north you exclude australia and the
new zealand you have people who
more and more are missing in
food and I still have one
another element of reflection for you
to be careful when we talk about agrico
home not to lose this idea of
agricultural performance
if you look at fao numbers
in 1960 we were
two humans for one Arab hectare in
big every human on earth willing
about half a hectare to
feed in 2007 we had more than
not even a quarter of a hectare and in 2050
we will have much less
of hectares 0 18 hectares per human
so when you talk about a
increase in the world’s population
that you are talking about a daniel decrease
the arable surface
compared to the number of inhabitants on earth
you can not start a debate about
agroecology without worrying about
agricultural performance and I’m going to
show a model that probably is not
not necessarily very viable it’s a
very recent publication of 2017 in
pns pns then for an idea for those
who do not know this game it’s
newspaper
this is the journal of the Academy of
American science it’s a journal in
terms of performance in terms of
recognition that aligns with the image of
nietzsche and the sayans for you
give a little importance to the newspaper and
that’s the result of an experiment
in large scale that compares a
conventional agriculture in orange
organic farming in glass and
in a reduction of yellow inputs is this
that you look at both for corn
for soy and for wheat pretty much
in all situations a
decrease a division by two of
the efficiency of agricultural production
when we move from a conventional model
which we could discuss the good done to
a model of agricultural biology
biological
so this game tell you is it takes
really pay attention to the aspect
overall things there are people who
continue to eat with a lot of
difficulties in the world and I you
also speaks of a French example
when you look at this curve in 1960
an average French they were spending
a third of his salary to feed himself
currently we are between 15 and 20%
risk of non- performing agriculture
it’s the price of
supply
and when you look at what’s going on
right now on the rising price of
fuels
I do not do any drawing on what
could happen in terms of
higher food prices
we have a social duty as a
thinker of tomorrow’s food we
can not exclude this human aspect
things for people
who are not inhabitants of
city ​​centers easy the last point c
is a israel coat really
disgusting and you have an example of a
sir who has worked for a very long time at
the TV and who has been repeating that
the food is disappointed she was from
shit so that’s something that
annoy me because it’s a bit my
job is not completely fair in
all professions have sheep
black
we have heard but I
would like to emphasize three aspects
important food
industrial
salt intake does it
Power is it really
bring more salt and you understand
why I will explain why
I made this choice
is the food a record?
leads to more energy expenditure and
is the industrial feed
is not there to intervene on a
shared task relationship between man
and the woman take the first point
feeding as a vector of
diseases then you have a lot of
publication that came out which one the
last one this coming from a
researcher of inra
ultra- processed food stop
so the first question what is this
that an ultra transformed food then
you have the example in my back there you
have the example of Bayonne smoked ham
it’s an ultra food transforming
yogurts processed foods
we always think of plates of
prepared dishes etc but you have some
foods that seem extremely
roughly 80% of the
foods that are consumed are
ultra processed foods so I
chose that one because he’s sorry
it is very rich in salt
wait I’m coming back here it is
is very rich in salt and he presents it
a major disadvantage in terms of
public health
that’s the disadvantage it’s
stroke
Then for a long time that there
a very strong relationship between the
salt intake and frequencies
cerebrovascular action example
Finnish is a case study
the Finns were the people who
were eating in the world probably the
more salty and who had the frequencies
stroke
more important and finland chose
to have a policy extremely of the
term of communication game about salt
and at the same time in terms of taxation
on salt and it was found that at
over the years there was a fall from
salt consumption in finland and
that parallel in the curve
central you see we have a decrease
of mortality in parallel with the
decrease the race Le Mans a
decrease in accident mortality
cerebrovascular
so yes the salt is important look
in detail of industrial foods
we will take a first case the bolt
does chicken broth bring
way too much salt so I’m taking
the sacred sacrament of a descendant
Italians the right rule for cooking
pasta and if you calculate it that you
does 10 grams per liter if you take
recommendations chicken broth goes
you get to 9 grams per liter in
pretty much the same thing as the
Italian rule
let’s take second product that a product
for babies but I took a recipe
of a mashed potato and when you look at the
recipe and you do the math you
get to a salt rate twice
higher than the level of salt present in
the food is all about baby and if you
let a mom do it she’ll do her
mashed according to his own tastes and there is
probably big chances she
gives his baby a tower is twice
higher in salt concentration at a
pure and manufactured by an industrialist
last product tomatoes sauce
like blabla aps tomato rice soup
date and if you do the math and that
you rehydrate the tomato you get
a soup whose salt content is at
about two times less than
preference preferences which
had been determined in a newspaper in
1999
so let’s continue the debate and start on
is the food industry
consumes
more fossil energy so why do I
I’m interested in fossil energy while
simply because watching
not only we have beautiful
illustrations right now on the rounds
points
but if you look here what we
call the peak oil
that is to say the maximum of productions
possible oil the curve in red
see me we’re practically pick
roll that is to say that tomorrow we will have
less and less oil after
tomorrow will have noises at least gas and
after after tomorrow will have less in
less uranium and less and less
coal therefore to a real problematic
energy and this is a major problem
and this major problem it does not concern
that displacements that not concern
that light does not concern that the
heating it relates to the feeding of
extremely acute way when you
eat you cook so I took a
example of an extremely
recent two of 2018 look
extremely recent that compared
different factors and I chose
especially these factors to center me
than on the energy aspect the used because
ben fossils and what are you
look at the conclusion of people who have
betrayed to whoever appears
making a traditional dish at the
house in blue and by industry in
orange we have nice in a bad year pretty much
same energy consumption why
simply because the tool
industrial
look at half of the energy first
in both cases is consumed by the
production of food ingredients and
when you cook a food india us
so much at home you have on
the whole energy used 30% that
comes from your cooking method
we had to be food the tool is
much more efficient we reach 13%
where is the food industry
fishing in the transport actually on
has 10% instead of 10% and especially 14 for
its packaging the problem of packaging
that a recurring problem if you take
now the sterilization ie
canning
then there is no common measure if
everyone starts to make
house concerts we would need
multiply by an inconsiderable number
the number of nuclear power plants all
simply because the industrial tool
is here is extremely powerful in
energy recovery term in
terms of sterilization scales then
what’s the point of actually sterilizing a
food just eight fell
sick
and the big problem of feeding
it is the sterilization the suppression
pathogenic bacteria and watch
this curve of the ined it is very
interesting
1871 Mr. Pastor explains to
mothers who must be sterilized
baby bottles
terry zealous and from that moment on
well before the invention of penicillin
you have a decrease in mortality
infant what to remember
is that in the diet the
conserve consume energy
it allows us to eat in the
winter periods it allows us
to avoid getting sick but that
represents an energy cost
considerable and the industry is a way
to save that energy that will be
more and more rare then last point
What does the agri-food industry bring
the just do you a little
comparison between men and
women in red the time households and
women in blue both households and
men
you will notice who works a lot
women at home and on time
spare fans at one-third of the time
housework happens in the kitchen
when you look between 1985 and 1998
2010 you have a very discount
important time spent cooking and
when you compare parallel to the
consumption prepared meals that did
ceased to grow since the 1960s and
the increase of canned vegetables
and potatoes that have announced this
grow the iconoclastic question put me
a glue bequeaths a woman who does the
cooking is to tell me is it
agribusiness was not among the
factors contributing to the accession of work
Women’s
little iconoclastic question that I you
pose here then in conclusion what is
important to say is that maybe he
there are problems of time scale no
only the vision of things is a
a little centered vision of city centers
how to combine bonuses
food this well downtown
a little bit easy but especially a
take time scale when you
compare for example the policy
agricultural ministries pac
we are in preparation for 2027 when
you will have practically more
oil in 2070 more gas in 2100 and
more coal and
fissile material in 2150 this
scale problem
we can also present them for example
the difference between pac 2027 and life
farrow which is the program at 2050 life
to our problem is to ensure the
security of people’s livelihood
food supply and when
you look at the different scenarios
of demographic costs looked at the
forecast is at 2100 when you look
the forecast of the INSEE on the
aging of the population we are going
from 10% to over 65 to 28% in
in looking at the forecasts of 1070 he’s me
seems that when we take care of
to renovate the way of producing
foods to transform them it takes
take into account of scale a lot
bigger in terms of time watching
in a much more comprehensive way the
surface of the planet to have a
analysis that is more accurate in the
reform to lead in agricultural matters
in food
I would like to thank pics to d for the
supply free images and I
would like to thank the organizers of
trust me
as well as your presence thanks to you
