talked about these environmental threats

play00:27

are doing something about them and I'd

play00:29

like you to see what they've done in the

play00:31

small East African nation of erria using

play00:34

pure seawater to grow food for people

play00:37

and animals and through that effort put

play00:39

hundreds of developing World citizens to

work as you watch this incredible story

play00:44

unfold just imagine it happening in

play00:47

thousands of other places from the Red

day each person needs about 2,100 kilo

play01:25

calories and they're not getting

play01:26

anywhere close to that people say every

play01:28

four or 5 years it's going to be another

play01:30

serious drought it's how airri is able

play01:33

to handle the drought and respond to it

play01:34

that's going to

although its roots are ancient Eritrea

play02:35

is the youngest Nation on the African

play02:38

continent revolution has marred its

play02:48

underway one that has nothing to do with

play02:51

guns and

play02:56

at claiming freedom from the Relentless

play02:58

drought that drains the nation's

play03:00

resources and saps the energy of its

play03:03

people hello there how are

play03:06

you all these beautiful young children

play03:09

depend on goat milk camel milk and they

play03:12

normally depend on a little bit of grain

play03:14

they grow um uh maze corn and another

play03:18

year you could see it growing here this

play03:20

year zero NADA because of no

play03:26

rain it is here on the Red Sea near the

play03:29

supp Port City of masawa that the war

play03:32

against drought is taking rote this new

play03:35

Revolution has replaced guns and tanks

play03:38

with technology and human

play03:40

resolve seawater Farms Eritrea and the

play03:43

desert development foundation have

play03:45

joined together with International

play03:48

investors and the government of Eritrea

play03:50

to establish the world's first

play03:52

commercial seawat Farm it has created

play03:56

jobs for over 400 errans and also sered

play03:59

serves as a laboratory for marine

play04:01

biology students from the University of

Arizona Hodes believes that growing

play04:20

seawater loving plants in desert areas

play04:23

could have a profound effect on

play04:24

eritrea's

play04:28

future

play04:32

this technology seawater agriculture

play04:35

when it's finally in all of its Glory

play04:37

with with maybe 20 or 30 agronomic crops

play04:40

with a whole spectrum of aquatic

play04:46

animals will eliminate the possibility

play04:48

of famine in Atria forever it will be

play04:51

gone and in fact it will make arria an

play04:54

exporter of food so it has tremendous

play04:58

potential

play05:02

the benefits are

play05:03

three-fold exporting Seafood brings

play05:05

dollars into eritrea's economy and

play05:08

provides employment for its

play05:10

people the principal field crops of

play05:12

salicornia and Mangrove have many uses

play05:16

including much needed ruminant feed for

play05:18

the country's

play05:19

livestock and The Greening of any

play05:21

portion of the Earth's surface reduces

play05:23

global warming believed by many to be a

play05:26

contributing factor to Global

play05:28

drought the seawater Farm was begun in

play05:32

1998 with the dredging of a channel that

play05:34

allowed water to flow from the Red Sea a

play05:37

saltwater river flowing Upstream into

play05:40

the

play05:45

desert freshwater agriculture was

play05:48

invented about 10,000 years ago mean we

play05:51

could stay home and somebody else would

play05:53

grow our food all of our cultures built

play05:55

on it but now we've run out of fresh

play05:58

water this is seawater this is a river

play06:02

of seawater coming

play06:04

Inland the newly created thre M long

play06:07

river meanders purposely through

play06:09

seawater Farms first filling large tanks

play06:12

that anchor the farm shrimp

play06:14

operation the water continues its route

play06:17

to enrich commercial fish

play06:19

ponds then twice enhanced with nutrients

play06:22

from the shrimp and fish effluent the

play06:24

river flows on to irrigate and fertilize

play06:27

agricultural crops

play06:30

eventually many weeks or months later

play06:33

having been biologically cleaned as it

play06:35

is filtered through the ground the water

play06:37

makes its way back to the Red

play06:41

Sea the goal of of this shrimp farm is

play06:45

to produce an export crop for irraa so

play06:49

that they can sell this and bring

play06:50

foreign currency in and at the time

play06:53

we're selling our shrimp in Europe

play06:55

they've been sold in uh Paris and London

play06:58

and we tried to keep our our um cropping

play07:02

plans flexible so that we can provide

play07:04

different sizes of

play07:07

shrimp this Farm is a completely closed

play07:10

cycle in the sense that all the effluent

play07:12

from these shrimp ponds goes on to

play07:15

salicornia farm and eventually to the

play07:18

wetlands and salt production none of it

play07:20

ever goes back to the ocean and as far

play07:23

as I know it's the first Farm that's

play07:24

ever been built like that and that

play07:26

addresses the contamination and

play07:28

pollution uh issue so

play07:32

successfully ponds of Tilapia a food

play07:35

fish being raised for the marketplace

play07:37

are fertilized with water from the

play07:39

shrimp

play07:41

operation later the enriched pond water

play07:44

is siphoned off to irrigate fields of

play07:49

salicornia salicornia is a hopy one of a

play07:52

family of plants that grows in pure

play07:55

untreated

play07:57

seawater this is a Comm commercial scale

play08:00

farm right here this salicornia field

play08:03

salicornia is exciting because you have

play08:05

the green plant when it's young you can

play08:06

eat it like a vegetable when you harvest

play08:09

the seed which is about 20% of the total

play08:12

biomass of that seed 30% is a high

play08:15

quality vegetable oil like safflower oil

play08:17

for cooking or salad dressing and the

play08:20

meal the 70% that's left behind is as

play08:22

good as soybean meal it's high protein

play08:25

you can use it to as a supplement to

play08:27

human food you can use it in animal

play08:29

diets it's truly an exciting

play08:32

plant salicornia also has commercial

play08:35

value in the strong composition building

play08:38

material that can be made from its dried

play08:42

husks the concept is to cover every

play08:45

square inch of land so we're maximizing

play08:48

the benefit of solar energy here the

play08:51

input energy is representing money in

play08:55

addition to being used for fodder this

play08:58

ornamental alite is also used to for

play09:01

cooling the climate in the local

play09:06

area this ground cover is also very

play09:10

helpful in stabilizing the soil against

play09:13

wind

play09:16

erosion this plant if I don't break it

play09:19

off has something underground that is

play09:21

critically important let me rinse it off

play09:24

this sand that that plant was growing in

play09:26

has essentially no carbon this root

play09:30

structure is a

play09:31

carbohydrate good agricultural soil

play09:34

which this will become over many many

play09:36

years has 16 to 18% carbon so what we've

play09:40

done is we've taken fossil fuel oil from

play09:44

Plants millions of years ago put it into

play09:46

the air as carbon dioxide made our life

play09:50

good by using energy we're now with

play09:52

intelligence taking it back out

play09:54

generating wealth This Is wealth above

play09:56

ground wealth and we're creating high

play10:00

carbon level soil for future Generations

play10:02

this is the way to solve global

play10:10

warming if there's one area on the farm

play10:13

I hope everybody understands it's this

play10:16

this is seawater forestry

play10:18

farming it is not forestry in the

play10:21

classical sense these are mangrove trees

play10:24

that are 2 years old they were seeds 2

play10:26

years ago when they were when we planted

play10:29

them 25 per square meter we planted them

play10:31

this far apart then when they were one

play10:34

year in we cut every other tree when we

play10:38

did that we got an incredible yield we

play10:40

got 10.6 metric tons of stems per hectar

play10:44

per year probably more importantly we

play10:46

got 18 metric tons of leaves for animal

play10:50

feed dry weight of leaves and we left 35

play10:53

tons of roots per hectar stored in the

play10:56

soil these are the roots of the mangr it

play10:59

makes roots and sticks them up so that

play11:01

even when this is being arrogated it can

play11:03

breathe oxygen this was the diameter of

play11:06

a mangrove tree one year old here's one

play11:11

2 years old you can see the incredible

play11:13

growth with this part missing that's

play11:15

what a mangrove seed looks it

play11:17

falls if the roots start out find the

play11:20

ground it turns up and in 2 years

play11:23

that'll be a tree this big as the trees

play11:26

get bigger they're building

play11:27

material and as the forests increase in

play11:30

density they will provide firewood

play11:33

already a commercial honey crop is being

play11:37

harvested flamingos herons and more than

play11:42

200 other species of birds have already

play11:45

found refuge in the fledgling

play11:47

Forest The Mangrove industry has also

play11:50

offered a Haven for a Cooperative of

play11:52

women who have become the Guardians of

play11:55

the forest they pick and sell the

play11:57

mangrove leaves that are used used as a

play11:59

component for animal feed so this is

play12:02

like the the pilot group it's 27 uh

play12:06

widows Mo mostly not all of them but the

play12:10

idea is to have a program where they

play12:13

have they can have

play12:15

education but the main thing is to

play12:18

number achieve that these women become

play12:21

self-sufficient from the forestry so

play12:24

these women and are experts on mangroves

play12:26

they know how to grow it take care of

play12:28

them they see

play12:29

uh the times the everything they can

play12:32

teach you whatever you want to know

play12:33

about mangroves the number thousands

play12:36

more lury here in nria is very very very

play12:39

low I don't know exactly but I don't

play12:42

think none of the women knew how to ride

play12:44

and breed before coming

play12:46

here and now mostly all of them know how

play12:51

to do

play12:57

that

play13:00

one of the greatest potentials here in

play13:01

arria is uh livestock production um

play13:05

obviously in a place like this that's uh

play13:07

drought prone um you can't really talk

play13:09

about growing large amounts of Wheat and

play13:11

large amounts of cereals here so we have

play13:12

to look at livestock if we can develop

play13:15

this um halite based uh small ruminant

play13:18

feed and we can grow animals here and we

play13:21

can feed them on basically seaweed

play13:23

mangroves that kind of thing then that

play13:26

idea can be replicated up and down the

play13:28

up and down the Red Sea

play13:29

Coast why couldn't we do it in any place

play13:32

along any Coastline where seawater

play13:34

plants grow and there's a need for

play13:37

economic development which describes a

play13:39

tremendous part of the

play13:41

world the arrian coastal area is the

play13:44

origin of human

play13:47

being human beings have their Roots here

play13:50

and um I would like to see everybody

play13:52

coming here to see his roots people from

play13:54

over the world the humanity you know

play13:56

it's also the the roots of the second

play13:58

Agricultural Revolution it started

play14:01

10,000 years ago CU now we're using

play14:03

seawater we're battling against human

play14:07

ignorance we're battling against human

play14:10

greed people that want look at the

play14:14

developing world as a place to make

play14:15

money exclusively not putting it in a

play14:17

broad enough

play14:18

context we're battling against

play14:21

time basically what we're doing is we're

play14:24

taking human

play14:27

intelligence photo synthesis putting

play14:29

them together correctly when human

play14:31

intelligence built those

play14:33

tanks the whole agenda of war was not

play14:37

the best use of human intelligence if

play14:39

you're defending yourself if you're

play14:40

fighting for Independence yes once

play14:42

you've got it a much better use is to

play14:45

let all these remnants that you see

play14:47

around here tanks laying and

play14:49

seawater that will dissolve over the

play14:52

next 25 years and those iron molecules

play14:54

will be in those mangrove trees that's a

play14:58

much better use of human intelligence

play15:00

and it's a much more thrilling and

play15:03

rewarding war to

play15:05

fight cycles of drought will continue in

play15:08

arria for Drought is no stranger to the

play15:11

Horn of

play15:12
