a radical change of focus surely

the most transcendent that they are going to talk about today

in the sense that it will affect each

one of your lives in each of your

moments and also the important news

is that it is not an option to climate change

I had all heard about the change

climatic the big issue in the agenda

global agreement

the news about climate change is

that does not come alone

first news is accompanied by

changes in the availability of resources

as water energy food maybe all

type of goods

the second news is that we are not going to

be able to do anything to stop it

we are late to even voices

authorized as that of lovelock one of

the founders of greenpeace that foresees

by the end of the century, scenarios of the type

only 500 million human beings

surviving in the cheeks of

planet the polar caps

but we’re not going to let this happen is

truth I believe that it can not disappear

all the imagination and intelligence the

power that has led to the human being

has brought us to where we are and from

soon we are going to take on a slope

down to the tragedy

sure that we will be able to do

something better sure we’re going to be

able to travel beyond a

worthy form and this is the talk of

today

so far the fight against change

climatic was based on a parameter with

the one that be familiar the

sustainability

let’s make our way of life

be sustainable

well sorry we are late

40 years ago we have been talking about

sustainability and we have not been able

to react in time

now what we have left is another concept

the resilience

this may already have heard some

less of you

the resilience simply be able

to resist an impact and follow

working after one way or another

because this is what we are going to have to

think about the strategies to travel

for this crisis that we are already beginning

to live this climate crisis and

energy and reach a world where

we can live in a way worthy of a

happy way because they do not come let’s go now

focus on the scenario that we are going to

have to manage the city

the human being comes living in cities

nowadays already mostly the

human species live city ​​and for

at the end of the century we are probably

in environments of 70 to 80% of the species

human being living in large cities

cities

surely the excessive growth

of the city that is an important part

of the origin of this problem that we are

living

therefore if the cities are not

also the solution if the

modifications of the parameters of the

cities do not become the solution

to that resilience we can see ourselves in a

collapse of civilization as the

we know

the climate in the city

so climate change and city

we are all already feeling in a way

very direct very recognizable in what

terms is giving this change in the

Middle latitudes where a large part lives

of the human population the majority as

in Seville for example here you go to two

tourists suffering from the climate that already

you know, you are checking

temperatures with a frequency never

registered extensions of the period

calyx never registered

this is the scenario we are going to

have to face each time with more

intensity think that the human species

we are going to live

temperatures that our species and ever

has lived of exists on the planet

the stage is of this caliber

also in the city he has recorded for a

phenomenon that is already well known that the

called heat island that you have

represented in this graphic agreement

the heat wave very briefly is the

ability of the city to accumulate and

produce heat and average machinery from

solar radiation transport and problems

to dispel what by its very nature

and by the regime of winds interrupted

as a consequence the temperatures in

city ​​centers can

get to be much higher than in the

periphery 8 10 12 degrees depending on the cases

the time of year the moment and the

morphology of the city

what do you mean by the news

they say that in seville a summer day

forty four degrees ago which

more and more frequent is the temperature

average at the airport outside the

city

as a result in the center of the city

you can be living temperatures

easily 56 degrees in the shade

imagine what we are facing

because a city that is not habitable

that is not comfortable

we can not say that it is sustainable not

we can say that it is recent so

We also talk about also

problems with energy imagine that

that scenario is taking place in a

city ​​where we can not pay the

energy to heat buildings or to

transport us in vehicles in what

situation leave us then we have to

imagine another city

we need now without an authentic

change of focus in this image whose

author I think that is presented a

magnificent artist sevillano chiqui lópez

best friend is very well synthesized

we have to think of a city that

appetizing in a city say this is not

goes from tragedy and fleeing towards

apocalyptic scenarios is not going to be

able to really imagine a city

much better and that also works very

well in that new climate in that new

vital scenario a city that will have a

change of focus in its urban landscape

in your building in your way to

relate to your economy in your

production in its self-sufficiency with

concrete strategies that we have to

to plan

we need a city absolutely

reforested as you see

we need to live almost an urban forest

and that’s appetizing and that’s nice

that is a city that we want

we need buildings that are

comfortable by itself very

comfortable without the need for energy and

that contribute so much self-sufficiency and

that we also need that energy

occur in the city we need to be

owner of the energy and we have a lot

available precisely was going to have

we are going to have more solar radiation

very good ‘are more energy are more

wealth

we need a different type of life in

the one that all our network functions

develop within a reasonable radius in

that we can go cycling

without the need for large displacements

is not that appetizing is not a kind of

life that we want, yes, but that

it involves reorganizing the city not

forget about zoning is that

therefore implies means of transport

distinct that are not contaminants that

do not demand energy we need

supposedly a different governance

we need one to think in terms of

different social organization we need

in short it is a challenge of great depth

definitive is to rethink the city such and

as we know nowadays

politicians it is clear that in the past

40 years need for in room 200

have not lived up to the

circumstances have not been able to

do it so we have to do it

we have to organize ourselves

socially

I would dare to say that resilience

of a society will come measured by its

capacity for social organization in

Seville have had a magnificent example of

control of the urban microclimate

for example expo 92 where

they got through strategies

bioclimatic reduce the temperature in

up to 68 punctually 10th time in this

graphic like what is a thermography

aerial as the center of Seville is

almost on average 8 degrees above the

expo 92 in the middle is the guadalquivir

according to that we have that technique

available in 25 years has not been applied

in the city so we are the

citizens we have to

organize ourselves in a different way

we have to think in terms of network

Social

we have to think in terms of

horizontal organization

there are many movements that should

be working and they are in fact

running the network of cities in

transition for example that already explained in

a mythical tedh talk in 2011 its

founder rock kings have generated

magnificent products all over the planet

but it’s still a small percentage all

you have to be involved

Here in Seville we have founded a group

of citizens the network of Seville by

climate with the same objective actions

concrete recognizable actions that

produce measurable results and

immediate

in that sense we have not implied by the

education in schools because the

new generations are fundamental

we have given prizes very people

meaningful

We have participated in projects of

urbanization of the hand of the neighbors

we have promoted the rooftop contests

green to make citizens

be aware of the possibility of

of the buildings where they live

we have criticized solutions

unfortunate as you see

because it’s amazing that this ride

fluvial just opened belong to

a city with a climate like Seville

opposed however another kind of

solutions for projects that are being

because ultimately making

we need a new society

we need another image of city and the

we need now we can not stay

with the city that we have between

hands

we have to think that the challenge that

we have what we have to solve between

we the challenge is huge but you must

of surely having a better future and

that future is a future that we can

choose us

thank you very much

[Applause]
