00:00:13

I guess all of you have a smartphone or an iPhone,

00:00:18

and this morning, probably you checked on the weather,

00:00:22

if its going to be rainy to carry your umbrella,

00:00:26

if it is going to be sunny to use your sunglasses,

00:00:29

or if it is going to be cold to have an extra coat.

00:00:34

It's going to give you, sometime, good information and sometime not.

00:00:39

Let me tell you,

00:00:42

my best app is my grandmother.

00:00:45

(Laughter)

00:00:49

She's called Mamadda.

00:00:51

She can tell you not only today's weather

00:00:55

but she can predict the next 12 months,

00:00:58

if it's going to be a good rain season or not.

00:01:03

She can tell you just by observing her environment,

00:01:07

by observing the wind direction,

00:01:09

the cloud position,

00:01:11

the bird migration,

00:01:13

the size of fruits,

00:01:15

the plant flowers.

00:01:17

She can tell you by observing the behavior of her own cattle.

00:01:23

That's how she knows better the weather and the ecosystem

00:01:28

that she's living in.

00:01:31

I'm coming from a pastoralist community

00:01:35

who are cattle herders.

00:01:37

We are nomadic.

00:01:39

We move from one place to another one

00:01:42

to find water and pasture.

00:01:44

We can move up to a thousand kilometers, the size of California, within one year.

00:01:51

And this life helps us to live in harmony with our ecosystem.

00:01:58

We understand each other.

00:02:01

For us, the nature is our supermarket,

00:02:04

where we can collect our food,

00:02:06

our water.

00:02:07

It's our pharmacy where we can collect our medicinal plants.

00:02:12

But it's our school,

00:02:13

where we can learn better how to protect it

00:02:17

and how it can give us back what we need.

00:02:22

But with the climate change impact,

00:02:25

we are experiencing a different impact.

00:02:32

In my community,

00:02:35

we have one of the top five fresh waters in Africa.

00:02:40

It's Lake Chad.

00:02:43

When my mother was born,

00:02:45

Lake Chad used to be about 25,000 kilometers square of water.

00:02:52

When I was born, 30 years ago, it was 10,000 kilometers square.

00:02:59

And actually now,

00:03:01

it's about 1,200 kilometers square of water.

00:03:06

Ninety percent of this water just evaporated, disappeared.

00:03:12

And you have more than 40 million people

00:03:16

living around this lake and depending on it.

00:03:20

They are pastoralists.

00:03:21

They are fishermen.

00:03:23

And they are farmers.

00:03:25

They do not depend on the end of the month's salary.

00:03:29

They depend on the rainfall.

00:03:31

They depend on the crops that are growing

00:03:34

or the pasture for their cattle.

00:03:38

The shrinking resources,

00:03:40

you have many communities that are fighting to get access.

00:03:46

The first come is the first served.

00:03:48

The second have to fight unto death.

00:03:54

So climate change is impacting our environment

00:03:59

by changing our social life,

00:04:04

because the role of man and woman in this region, it's different.

00:04:10

Man is supposed to feed his family,

00:04:13

take care of his community,

00:04:16

and if he cannot do that,

00:04:19

his dignity is under threat.

00:04:24

He cannot do anything else to pay it back.

00:04:29

So climate change takes our men far away from us.

00:04:35

That is the migration.

00:04:38

They can migrate to a big city where they can stay for six or 12 months,

00:04:44

where they get a job, they can send back money.

00:04:49

If they didn't get it,

00:04:50

they have to jump into the Mediterranean

00:04:52

and migrate to Europe.

00:04:55

Some of them die there, but none of them stop going.

00:05:02

Of course, it's sad for the hosting country,

00:05:05

who are developed countries,

00:05:08

who have to adapt to host the migrants coming.

00:05:12

But how about those who are left behind,

00:05:16

the women and the children who have to play the role of men,

00:05:20

the role of women,

00:05:22

who have to take care of the security,

00:05:23

of the food, of the health of the entire family,

00:05:27

children and old people?

00:05:31

So those women for me, they are my heroes,

00:05:37

because they are innovators, they are solution makers,

00:05:42

they are changing the little of the resources

00:05:45

into the big for the community.

00:05:48

So those are my people.

00:05:52

So we use our indigenous people's traditional knowledge

00:05:57

to get better resilience to what we need to survive.

00:06:05

Our knowledge is not only for our communities.

00:06:08

It's to share with each and others who are living with us.

00:06:14

And indigenous peoples around the world

00:06:16

are saving 80 percent of the world's biodiversity.

00:06:22

That's the scientists who say that.

00:06:25

Indigenous peoples in the Amazon,

00:06:29

you can find the most diverse ecosystem, better than the national park.

00:06:36

The indigenous peoples from the Pacific,

00:06:39

the grandma and the grandpa,

00:06:42

they know where to get food after the hurricane hits them.

00:06:49

So the knowledge that our peoples know

00:06:52

is helping us to survive and helping other peoples also to survive

00:06:56

the climate change impact.

00:06:58

The world is losing.

00:07:00

We lost already 60 percent of the species,

00:07:05

and it's increasing every day.

00:07:09

So one day, I took a scientist to my community.

00:07:14

I said, you are giving the good weather information through the TV and radio,

00:07:20

but how about coming to my people?

00:07:23

And then they come,

00:07:26

they sit around,

00:07:27

and suddenly, as we are nomadic, we just start packing our stuff,

00:07:32

and then they say, like, "Are we moving?"

00:07:34

I'm like, "No, we are not moving. It's going to rain."

00:07:37

And they're like, "Oh, there's no cloud. How do you know it's going to rain?"

00:07:41

We're like, "Yeah, it's going to rain." We pack our stuff.

00:07:45

Suddenly, heavy rain starts coming,

00:07:49

and we are seeing the scientist running around, hiding under trees

00:07:53

and protecting their stuff.

00:07:54

We already packed ours.

00:07:56

(Laughter)

00:07:58

After the end of the rain, the serious discussion starts.

00:08:03

They say, "How do you know that it's going to rain?"

00:08:06

We say, "Well, the old woman observed the insects

00:08:11

taking the eggs inside their homes,

00:08:14

and while the insect cannot talk or watch TV,

00:08:18

they know how to predict to protect their generations,

00:08:22

how to protect their food.

00:08:24

So for us it's the sign that it's going to rain

00:08:28

in at maximum a couple of hours."

00:08:30

And then they say,

00:08:32

well, we do have knowledge,

00:08:35

but we do not combine ecological knowledge and weather knowledge all together.

00:08:41

So that's how I started working

00:08:44

with meteorological scientists and my communities

00:08:49

to give better information to get peoples adapted to climate change.

00:08:57

I think, if we put together all the knowledge systems that we have --

00:09:03

science, technology,

00:09:06

traditional knowledge --

00:09:08

we can give the best of us to protect our peoples,

00:09:13

to protect our planet,

00:09:15

to restore the ecosystem that we are losing.

00:09:19

I did that in another way, also.

00:09:21

I used a tool that I really love a lot.

00:09:25

It's called a 3D participatory mapping:

00:09:29

participatory, because it can bring women, men,

00:09:35

youth, elders,

00:09:37

all the intergenerational peoples.

00:09:40

Then they use science-based knowledge,

00:09:44

and the community comes together, they build this map,

00:09:47

they figure out all the knowledge that we have

00:09:50

about where is our sacred forest, where is our water point,

00:09:54

where is our corridor,

00:09:55

where is the place that we move during each season.

00:10:01

And these tools are amazing, because it's building capacity of women,

00:10:06

because in our communities

00:10:09

women and men cannot sit together.

00:10:11

Men talk always, women just sitting there,

00:10:14

but in the back.

00:10:16

They are not there to take any decision.

00:10:18

So after the men figure out all the knowledge,

00:10:21

we say, well, you call the women, "Come and have a look."

00:10:25

They say, "Yes, sure,"

00:10:26

because they've already done the first work.

00:10:28

(Laughter)

00:10:30

When the women come,

00:10:31

and they look at the map, they're like, "Mm, no."

00:10:34

(Laughter)

00:10:36

"This is wrong.

00:10:37

Here's where I collect the medicine. Here's where I collect the food.

00:10:40

Here's where I collect --"

00:10:42

So we changed the knowledge in the map,

00:10:44

and we called the men.

00:10:47

Well, they think about what women said.

00:10:49

All of them shaking their heads.

00:10:51

"They are right. They are right.

00:10:53

They are right."

00:10:54

So that's how we build the capacity of the women

00:10:58

in giving them a voice

00:10:59

in this 3D participatory mapping,

00:11:02

so women get the detailed knowledge

00:11:04

that can help the community to adapt.

00:11:07

And man have the bigger picture knowledge.

00:11:10

So when we put it together,

00:11:12

this map helps them to discuss

00:11:17

but to mitigate the conflict between the communities

00:11:20

to access the resources,

00:11:22

to share better these resources,

00:11:24

to restore it

00:11:26

and to manage it for the long term.

00:11:31

Our knowledge is very useful.

00:11:34

Indigenous peoples' knowledge

00:11:36

are very crucial for our planet.

00:11:41

It's crucial for all the peoples.

00:11:46

Science knowledge was discovered 200 years ago,

00:11:51

technology 100 years ago,

00:11:54

but indigenous peoples' knowledge, it's thousands of years ago.

00:11:59

So why we cannot put all of these together,

00:12:03

combine those three knowledges

00:12:06

and give the better resilience

00:12:07

to the peoples who are getting the impact of climate change?

00:12:13

And now it's not only the developing countries.

00:12:16

It's the developed countries also.

00:12:18

We saw the hurricane. We saw the flood around all the places.

00:12:21

We saw the fire, even here in California.

00:12:25

So we need all this knowledge to come together.

00:12:27

We need the people in the center.

00:12:30

And we need the decision makers to change,

00:12:32

scientists tell them,

00:12:35

and we tell them,

00:12:37

and we do have this knowledge.

00:12:39

We have 10 years to change it.

00:12:43

Ten years is nothing,

00:12:45

so we need to act all together

00:12:48

and we need to act right now.

00:12:50

Thank you.

00:12:52

(Applause)
