L’acqua nel cibo | Marta Antonelli | TEDxVicenza


[Music]

I have been dealing with water since 2008 since the day

in which my sister gives me a book

beautiful and that changes my life

the water wars of vandana shiva

today I’m here to talk to you about the

relationship between water and food a relationship

complex problematic too often

underrated but before doing this

I have to take a step back from the 1950s

we entered the antrum of peace, nor the era

geological characterized by

transformation by massive intervention

of the man on the planet that is standing

altering at the territorial level

atmospheric and hydrological profoundly

some of the changes taking place in the

anthropocene are irreversible before between

all climate change that does not

it is only an environmental phenomenon but

which has very strong social implications

economic policies change

climate has been connected in fact to the

the emergence of conflicts to migrations

of whole populations

and also to phenomena like that of the

large-scale land acquisitions

a phenomenon that when it happens in

denial of human right takes the

name of land grabbing ie of

land grabbing the planet is

literally covered with water but only

0.001 percent of this water that

covers the planet is available for

human use

in fact the rest is salt water or yes

find it in the solid state or it is not

water is also directly accessible

distributed in a pan

extremely unequal

we find in fact that almost 70 per

one hundred of the fresh water reserves are

concentrated and only in 13 countries of

world water problems have roots

on one side we find a kind of

scarcity that to its root in the

lack of water in a territory

this kind of scarcity affects one

one in five people on the planet and precisely

occurs when the amount of water

in an area can not meet i

needs of the population that live there

generally this kind of scarcity yes

find in countries that are widely

dependent on food imports and

soon we will find out why there is one

other kind of scarcity a kind of

scarcity much more worrying than the

previous because it happens in contexts

of poverty and affecting a person

out of four on the planet

this kind of scarcity and rooted

in economic and social conditions

institutions that preclude access

to the water part of the population

because it’s worrying why not

have the right to access to water

to water denied a right what

it should be that it is a human right

means not being able to get out of the

poverty trap

that’s why he has to worry about it again

more agriculture is the heart of the

problem

the elephant in the room this because

70 percent of the fresh water that

we take is dedicated to the

production of food and agricultural goods in

general this percentage goes up a lot

in dry or semi-arid countries up to

reach over 90 percent

agriculture is also a sector

important also from the point of view

in fact, the impact of emissions is

the second sector that puts more

so it is greenhouse gases in the atmosphere

right here we have to go to

analyze and understand the problem but

because agriculture feeds us and here that

we must also go looking for them

solutions

in the last 100 years the population is

grown exponentially but still

more water consumption has increased

at a rate that is equal to more than

double that of the growth of the

population

this because we have modified

deeply the way we live in

we have modified our own

consumption of food and to change the

Our eating habits our

we have expanded our diet

water footprint per capita level

individual we need indeed to

about 2 liters to quench your thirst with water

between 30 and 50 for domestic use but

every day every one of us needs

at least 2,000 liters of water to eat

this is because water is an input of

production is essential in the

food production at all stages

of the supply chain in particular in the first

the phase in the field the cultivation e

this is the intuition that had tones to the

professor of king’s college and mine

doctorate supervisor in calling

this virtual water water because

a water no longer visible inside

of food but that actually was

used to produce it to types of

different foods match imprints

different water we need indeed

of about a cubic meter of water for

produce 1,000 calories of vegetables but

we need five cubic meters of

water to produce 1,000 animal calories

but stop and look at the breadth

the water footprint is not enough

because what determines the

sustainability of a product is not

only the volume of water contained in

virtual way inside but it is the

respect for the vocation of a

territory

respect

of sustainable agricultural practices

context in which it happened and this that

goes to determine sustainability or

less than the product we carry on

our tables

what you see was the lake of aral un

lake between Kazakhstan Uzbekistan that in the

we have almost thirty years

entirely dried up to produce the

rice and cotton for export

this lake has doubled his

saline concentration

in the last 30 years the

volume of her from here to around 15

meters

the trade the agricultural trade the

food trade in particular

establishes a relationship a relationship

between me that I eat is the country where the

agricultural production took place

this trade this link

invisible also makes me vulnerable to

crisis books that can affect i

apparently distant countries but that

they can go to influence mine

food supply then mine

ability to eat certain types

of food for example in Europe on the 40th

percent of our water footprint

food comes from countries

extra-European and some of these are

extremely vulnerable countries from the point

of water sight jeopardizing

whole supply chains, for example that of

soy or cotton rice in the face of

this scenario as it appears on the

future

this is the answer I gave myself

if we do not change things, do not

they will indeed change, because they will change

in 30 years we will be 10 billion up

this planet

eight out of ten people will live in the city

living in the city means detaching oneself

progressively from food to live one

sort of alienation from those who have it

produced by how it was produced by

seasonality from the vocation of a

territory because we have a

available all at any time

of the year

and it is then from here that we must

restart

I believe in building a different future

first of all it is important to rethink

agriculture

agriculture of the future must produce

better then with more efficiency and with

less with less resources and important from the

political point of view give the

tools to invest in farmers

in their training in giving access

to technologies because indeed

can help us to move towards

more sustainable production methods

in particular small farmers from

our security depends on

food politicians also have a

another great duty is to quit

to subsidize agricultural productions that

they are harmful to the environment and that often

they do not even go in the direction of the

public health goals and we are

what we eat

so it is important that they take

this commitment to those who do research

the commitment not only to continue to

work to improve knowledge but

also to promote understanding

trying not to be afraid of occasions

beautiful and exciting like today’s

thus favoring the understanding of

people of people who like citizens

and as consumers , consumers of food

the power of

influence who food produces it

asking for traceability by asking

transparency demanding responsibility

social and environmental

before leaving you I want to tell you

one last thing there is a theory that

he speculates that between two people in

any point on the planet exists one

chain of no more than six intermediaries

what I ask you is to share

the ideas you heard today and about

ask your network to do

just because in this way me

you have helped transform the

knowledge in awareness that I believe

either to the weapon of mass construction or

more powerful than we have thanks
