00:00:54
in the billions droughts floods

hurricanes vast areas are being
00:01:01
devastated by environmental catastrophe
00:01:03
how many people will be forced to leave
00:01:06
their homes by the mid-century not due
00:01:08
to conflict in war but due to climate
00:01:11

people are fleeing rising waters others
00:01:52
droughts the world's population began to
00:01:58
soar about 200 years ago
00:02:00
soon it will top 10 billion greenhouse
00:02:03
gases are rising a pace the resulting
00:02:06
warming of the Earth's atmosphere is
00:02:08
wreaking havoc on the climate humankind
00:02:11
which is responsible for this warming is
00:02:13
becoming its victim more and more people
00:02:16
are forced to leave their homes
00:02:21
inequality is being exacerbated by
00:02:23
climate change wealthy industrialized
00:02:26
nations are polluting our air while the
00:02:28
main victims live in the global South
00:02:30
for example in Indonesia
00:02:35
Ponty bahagia which means happy beach
00:02:38
lies on the indian ocean due to rising
00:02:42
seas and heavy rainfall the village is
00:02:44
sinking into the sea the flooding
00:02:47
continues even now during dry season

[Music]
00:02:57
the local primary school is damned and
00:03:00
smells of rot parents say conditions are
00:03:03
intolerable and more than half the
00:03:05
children have been taken out of school
00:03:14
most jayati rahmatullah teaches in
00:03:17
primary grades he attended this school
00:03:20
himself and is determined to persevere
00:03:23
his classroom flooded for the first time
00:03:26
in 2013 conditions here are very very
00:03:32
difficult for us we often have to send
00:03:35
the children home when the classrooms
00:03:38
flood the children sit with their legs
00:03:40
in water regular instruction has become
00:03:47
impossible the children are falling
00:03:49
behind within the next five or six years
00:03:52
rahmatullah believes the school will be
00:03:54
submerged it will be abandoned along
00:03:59
with the village
00:04:06
what will it look like here three
00:04:08
decades from now in the year 2050 but at
00:04:12
that time there will be the most extreme
00:04:14
conditions of the weather forward with
00:04:17
our 17,000 Islands a lot of course and
00:04:20
that will be eaten up by the sea so life
00:04:25
will not be the same as here there's a
00:04:27
lot of illnesses there will be plagues
00:04:29
and the economic growth of the hook on
00:04:33
the whole world will be disturbed by
00:04:36
horizontal strife one against the other
00:04:40
because fighting for food water maybe
00:04:44
arrows her death will be the very sad
00:04:47
picture in 2050 for the Indonesian
00:04:53
special envoy the catastrophic impact of
00:04:56
unchecked climate change is the biggest
00:04:58
challenge facing humankind today ten
00:05:01
years ago the topic was barely on the
00:05:03
radar
00:05:09
Jakarta the capital of Indonesia with
00:05:13
some 10 million residents it's the
00:05:15
largest city in Southeast Asia around 30
00:05:18
million people live in the metropolitan
00:05:19
area making it the second largest urban
00:05:22
conglomeration in the world the fish
00:05:30
markets are located in North Jakarta the
00:05:32
scent of the ocean lies in the air
00:05:35
mixing with the odours of the city just
00:05:43
a few kilometers from the city center
00:05:45
the problems confronting this tropical
00:05:47
metropolis become apparent residents
00:05:50
struggle with smog heat heavy traffic
00:05:53
pollution population density and poor
00:05:55
hygienic conditions and with increasing
00:05:57
frequency flooding the slum district of
00:06:02
Dutta is located near the airport it's
00:06:04
5,000 residents used to live near the
00:06:07
sea but these days it almost looks like
00:06:09
they live in it EKOS umano has lived in
00:06:13
dot up since the 1970s he and his
00:06:16
neighbors have watched the rising sea
00:06:17
level with concern at least once a month
00:06:21
the flooding reaches his knees sometimes
00:06:24
the water remains two days sometimes a
00:06:27
week it flooded here for the first time
00:06:32
around the year 2000 first it was just a
00:06:37
few centimetres since 2010 the flooding
00:06:40
has been getting higher and higher but
00:06:43
it's never been as bad as it is now
00:06:54
in Jakarta the district's closest to the
00:06:57
coast faced the biggest problems poor
00:07:00
neighborhoods like Dada will be among
00:07:02
the first to need complete relocation
00:07:06
the slums most at-risk are situated
00:07:09
along a wide corridor that snakes
00:07:11
through the city says urban planner
00:07:12
Marco kusuma vijaya only about the
00:07:18
coastal areas the flood actually up
00:07:22
streams in the city center of Jakarta
00:07:25
Fabian dear from my office kusuma V Jaya
00:07:30
is director of the rujak Center for
00:07:32
urban studies which searches for
00:07:33
solutions for climate related problems
00:07:36
right now their focus is the depletion
00:07:38
of groundwater from the area the
00:07:41
declining water table has even more
00:07:43
serious consequences than rising sea
00:07:45
levels it's causing the ground to sink
00:07:48
and large parts of the city with it on
00:07:54
the way of Jakarta the sea level rises
00:07:57
at between 4 to 6 millimeters per year
00:08:02
but was is that the land of Jakarta is
00:08:08
subsiding by 3 to 20 centimeters
00:08:18
in February 2013 nearly half of Jakarta
00:08:21
was underwater scenes like this are
00:08:24
likely to become increasingly common
00:08:28
ocean levels continue to rise the land
00:08:31
is collapsing and heavy rains are
00:08:33
becoming more frequent about one third
00:08:38
of Jakarta is currently below sea level
00:08:40
environmental problems are causing a
00:08:42
growing number of people to flee the
00:08:43
city
00:08:44
but most want to remain or have no other
00:08:47
choice in an effort to protect the
00:08:49
capital the government has begun
00:08:51
building a seawall
00:09:02
but only six of the planned 50
00:09:04
kilometers have been built and even
00:09:10
their water is finding its way through
00:09:12
it's becoming clear that everything
00:09:14
located directly on the water will one
00:09:16
day fall victim to it like this mosque
00:09:20
the bad thing is actually most of the
00:09:23
poor neighborhoods will be flooded
00:09:26
because the rich neighborhood have
00:09:30
raised themselves you know but exactly
00:09:34
because they erase their ground so the
00:09:36
water that come to their ground will
00:09:39
actually flow into the surrounding poor
00:09:41
or neighborhood poor districts located
00:09:50
along one of Jakarta's 13 rivers often
00:09:53
stay submerged for weeks when the
00:09:54
floodwaters rise areas near the Chile
00:10:04
one river are most at risk like this
00:10:06
low-income district by the Chile one
00:10:08
tributary Tonk all situated just four
00:10:10
hundred meters from the ocean the
00:10:12
drivers housekeepers fishermen
00:10:14
construction workers in such that live
00:10:16
here all face climate change related
00:10:18
risks this estimated that 65% of our
00:10:23
operation will be directly victimized
00:10:27
weather which is a lot of people of his
00:10:29
65 percent of 300 million three hundred
00:10:33
million is 170 million people will we
00:10:37
are an island nation and around six
00:10:41
thousand islands are inhabited
00:10:43
because coastal areas will be destroyed
00:10:45
Steff they came up with figures of 14
00:10:49
million four zero million because they
00:10:51
are the coastal people and those are
00:10:53
prone to the effects of landslides so
00:11:00
about forty million people are directly
00:11:02
involved
00:11:04
and those involved may have to leave
00:11:06
their homes
00:11:09
[Music]
00:11:25
Indonesia is prone to a variety of
00:11:28
natural disasters from cyclones to
00:11:31
mudslides flooding to droughts but there
00:11:34
is one place that is at risk of all of
00:11:36
these the island of Java and it's here
00:11:40
that one of the world's most densely
00:11:41
populated areas is located Jakarta
00:11:49
the city's infamous traffic jams lasts
00:11:51
almost until midnight only to resume
00:11:53
again at dawn more than 3.5 million
00:11:58
people commute into the city every day
00:12:06
just 100 kilometers southeast the bustle
00:12:09
of Jakarta is a distant memory chan your
00:12:13
district is situated at the foot of two
00:12:15
inactive volcanoes it's one of Java's
00:12:18
most fertile farming regions
00:12:27
the rice vegetables and fruit grown here
00:12:30
help feed the country's capital the
00:12:33
village of Saranga is accessible only by
00:12:35
motorbike or on foot
00:12:37
dudu Durrani runs a small coffee
00:12:39
plantation here like his father and
00:12:42
grandfather he is a farmer coffee used
00:12:47
to be a safe crop choice it fetched a
00:12:50
better price than vegetables and was
00:12:52
harder than rice but that's changing
00:13:01
when I was younger all farmers would
00:13:04
plant during rainy season so January
00:13:06
February in March and then everyone
00:13:09
would harvest during dry season but now
00:13:13
my colleagues and I are desperate
00:13:14
because it's often dry in the rainy
00:13:17
season and in the dry season it rains we
00:13:22
are paying the price for climate change
00:13:24
our harvests have dropped massively by
00:13:27
about 60% nearly half of local farmers
00:13:33
have given up they've moved to other
00:13:35
parts of Indonesia or left the country
00:13:37
altogether some have become construction
00:13:40
workers in Saudi Arabia but doo doo de
00:13:42
Roni doesn't want to join them I can't
00:13:48
imagine doing anything else I will stay
00:13:52
here as long as possible I'm a farmer
00:13:54
that's who I am I'm going to try to
00:13:57
somehow adapt to climate change
00:13:59
if it's too dry when it's time to plant
00:14:02
for example I'll just wait
00:14:09
these mountainous regions don't just
00:14:12
supply food to the cities their forests
00:14:15
also help store rainwater but extreme
00:14:17
weather conditions are growing
00:14:19
increasingly common here and still
00:14:21
forests are falling victim to logging
00:14:24
leaving rain water to flow unhindered
00:14:26
into the valley sometimes the water
00:14:28
sweeps away everything in its path
00:14:31
[Applause]
00:14:41
mudslides have had fatal consequences

special climate invoice Hockman viitala

says that by mid century climate change
00:15:11
will have forced 40 million people to
00:15:12
flee their homes in Indonesia alone
00:15:15
farmers who can no longer till their
00:15:17

[Music]
00:15:41
most experts agree that it's the world's
00:15:44
coldest regions that have become the
00:15:45
cauldron for climate change these are
00:15:48
the Arctic the Antarctic Alaska and much
00:15:51
of the permafrost of Russia

00:16:10
Nikita Z mph trained as a mathematician
00:16:14
but his father Sarah's lifelong
00:16:17
commitment inspired Nikita to change
00:16:19
course now like his father he has
00:16:22
dedicated his life to preserving
00:16:24
Russia's permafrost he's come to the
00:16:27
Kalima River in northeastern Siberia an
00:16:30
eight-hour flight from Moscow to gather
00:16:32
evidence that the permafrost is
00:16:33
vanishing the ground has warmed up to 3
00:16:37
degrees Celsius causing the top layer of
00:16:39
the ice to melt one side effect is that
00:16:43
more and more rare fossils are surfacing
00:16:49
for paleontologists this would be a
00:16:51
treasure trove a field of riches from
00:16:55
the distant Pleistocene epoch mama swag
00:17:10
not the biggest one but every size 20 so
00:17:18
here was in the position the consistent
00:17:20
here was huge and own Everest quake
00:17:23
homes around one mammoth and labeled for
00:17:25
40,000 years and all never here on this
00:17:28
quake home to now lay around 600
00:17:30
skeletons so every once in a while there
00:17:35
all along the Kalima soil is eroding
00:17:38
sliding into the river as a consequence
00:17:41
of the melting permafrost
00:17:43
Nikita Zima calls plants like these
00:17:46
zombies because the soil in which they
00:17:48
are growing was Behrend for forty
00:17:50
thousand years this vegetation will also
00:17:55
soon end up in the river
00:18:00
the changes taking place here could soon
00:18:02
be a reality across wide expanses of
00:18:05
Russia and it could also have a dramatic
00:18:08
impact on the global climate and mass
00:18:10
migration of people's 4 there is an
00:18:12
immense amount of biomass still trapped
00:18:14
within the permafrost
00:18:16
[Music]
00:18:25
if that trapped co2 and methane were to
00:18:28
be released into the atmosphere the pace
00:18:30
of climate change would increase
00:18:32
dramatically so these are roots of
00:18:47
grasses which grew here maybe around
00:18:49
40,000 years ago
00:18:50
and the problem that is it huge storage
00:18:53
of carbon and take all these little
00:18:55
groups and put them on the one side of
00:18:56
the burns and on the other side of the
00:18:58
bones put all the background vegetation
00:19:00
of the planet so basically all trees and
00:19:02
shrubs of the planet you will see that
00:19:04
this tiny little roots wait more and if
00:19:07
Paris will start to degrade everywhere
00:19:09
all this will become a way for microbes
00:19:12
to eat and they were very soon
00:19:14
converting to greenhouse gases co2
00:19:16
methane that's ice pure ice out there
00:19:25
and you see when this ice is melting the
00:19:30
wood is mixed in with this soil and
00:19:32
creating this mud folks which are
00:19:33
children down the slope and the
00:19:35
gradations have been very rapidly here
00:19:37
so it's a combination of both
00:19:39
loads of carbon and lots of ice and
00:19:41
that's a give you a very rapid carbon
00:19:43
bond so every problem that will be
00:19:45
happening with the global warming
00:19:47
worldwide with this thing will be
00:19:49
probably amplified so if it will it will
00:19:52
see if it's going to be bad somewhere to
00:19:55
turn very bad so if there is a way to
00:19:58
stop that from happening like we need to
00:20:01
apply that because if not you know you
00:20:05
can write any apocalyptic scenarios you
00:20:08
want and probably most of them will come
00:20:10
true
00:20:10
[Music]
00:20:17
it's breakfast time in Nikita zoomorphs
00:20:20
guesthouse interest in permafrost has
00:20:23
soared over the past decade so now the
00:20:25
guest rooms here at the station are
00:20:27
usually booked year-round with
00:20:28
researchers from all over the world this
00:20:32
is the group from Oxford University here
00:20:34
to study the transformations currently
00:20:36
underway in what used to be frozen earth
00:20:45
during the Soviet era this enormous
00:20:48
satellite used to broadcast television
00:20:50
programming from Moscow the Z morphs
00:20:54
turned the station into a home base for
00:20:56
scientists from around the world
00:21:12
[Music]
00:21:17
yeah well most though the data that has
00:21:20
been collected in Siberia and across
00:21:21
Russia's Far East are alarming normally
00:21:25
the vegetation binds greenhouse gases in
00:21:27
the summer and only releases very small
00:21:29
amounts back into the atmosphere in
00:21:31
winter which is but for the past few
00:21:41
years the permafrost that's thawing more
00:21:43
and more in the summer is releasing
00:21:45
ever-increasing amounts of methane and
00:21:47
co2 during the winter
00:21:55
at the moment the biosphere is acting as
00:21:58
a well could be say as a friend as a
00:22:00
moderate break on climate change so
00:22:02
about 40% of the carbon dioxide we emit
00:22:05
is being absorbed by the biosphere and
00:22:08
that's acting to slow down climate
00:22:09
change if that wasn't happening climate
00:22:11
change would be even faster than it is
00:22:13
but one of the big concerns we have as
00:22:15
system scientists is understanding how
00:22:19
long will the biosphere keep acting as a
00:22:21
break and is there a danger that at some
00:22:23
time in the future with this break we'll
00:22:26
turn into an accelerator
00:22:31
scientists from all over are turning
00:22:33
their attention to the permafrost and
00:22:35
its potential impact on climate change
00:22:38
this group of researchers from Prague is
00:22:41
being hosted by the Institute of applied
00:22:43
ecology of the North in the Republic of
00:22:45
Sakha the researchers have just returned
00:22:48
from a crater that is carved into the
00:22:50
permafrost these soil samples are a gift
00:22:54
to the Institute in return the
00:22:57
researchers hope to obtain permission to
00:22:59
exhibit some of their spectacular finds
00:23:00
in a museum at home remains of a mammoth
00:23:03
and the mummified remains of an extinct
00:23:06
horse from the Pleistocene epoch the
00:23:17
crater in which the fossilized remains
00:23:19
were found was named the bottarga crater
00:23:21
but locals call it the Gateway to the
00:23:24
underworld
00:23:28
it's easy to see why
00:23:31
[Music]
00:23:51
in the 1960s a small section of forest
00:23:54
was cleared to make way for a new road
00:23:56
the permafrost originally beneath the
00:23:59
trees began eroding at first the hole
00:24:03
was just a few meters deep the stood on
00:24:07
average the mega crater is between 40
00:24:09
and 60 metres deep and in some places
00:24:11
it's 100 meters deep it's 1.5 kilometers
00:24:15
long and about one kilometer wide right
00:24:18
now but it's hard to determine exactly
00:24:20
how wide it is because it's expanding so
00:24:22
quickly these kinds of catastrophic
00:24:25
events could become increasingly common
00:24:27
and not just in residential areas but
00:24:30
anywhere in the wilderness wherever
00:24:33
there are pipelines and natural gas
00:24:34
facilities our entire infrastructure
00:24:37
could be impacted
00:24:42
most of the cities in Siberia and in
00:24:44
Russia's Far East could be affected
00:24:46
about 25 million people in all how big
00:24:50
would the impact be if all the world's
00:24:52
permafrost were to melt so far there
00:24:55
isn't enough cross regional research to
00:24:57
answer that but there are findings
00:24:59
regarding the polar region from a global
00:25:01
terrestrial network for permafrost in
00:25:04
1996 the permafrost melted to a depth of
00:25:07
45 centimeters in the summer by 2017 it
00:25:10
melted to a depth of 87 centimeters a
00:25:12
nearly 100 percent increase over just 20
00:25:15
years
00:25:23
this poses a danger to both people and
00:25:26
infrastructure natural gas and oil
00:25:30
pipelines are particularly affected
00:25:32
Greenpeace has estimated that leaks and
00:25:35
pipelines cost by thawing soil are
00:25:37
leading to about 1% of oil being lost
00:25:39
that oil some 5 million tons of it each
00:25:43
year seeps into the ground the residents
00:25:47
of the Arctic city of cesky in the far
00:25:49
northeast of Russia are bearing witness
00:25:51
to this rapid transformation
00:25:53
temperatures are rising inexorably
00:25:57
asphalt on the streets is beginning to
00:25:59
buckle and several buildings are showing
00:26:04
signs that the solid ground on which
00:26:05
they once stood has begun to sink
00:26:21
the city of chair ski on the kolyma
00:26:24
river is also home to Nikita Zi Moff
00:26:26
even though temperatures drop here to
00:26:29
minus 60 degrees Celsius in the winter
00:26:31
the erosion of the permafrost soil
00:26:33
appears unstoppable
00:26:35
this is especially apparent at the
00:26:37
former water treatment plant like all
00:26:42
the buildings here it stands on pillars
00:26:46
[Music]
00:26:53
the earth began to sink here just two
00:26:55
years ago now the crater is already 10
00:26:59
meters deep
00:27:05
as soon as it starts it's going very
00:27:07
rough so when I was here a week ago
00:27:09
there was some those two place with you
00:27:12
in the air and now we came they already
00:27:14
come up down and there is a huge niche
00:27:16
going underneath the purpose of where
00:27:18
this is this ice it's been eroded and
00:27:20
eventually all that slope you'll
00:27:22
collapse also so this process kind of
00:27:24
grow in them with I know centimeters a
00:27:27
day maybe tens of centimeters today
00:27:28
within the hot Baker so we have serious
00:27:30
building the firm fourth area and now
00:27:32
with climate getting warmer temperatures
00:27:34
also getting warmer and with degradation
00:27:36
it looks like that so all the
00:27:39
infrastructure in the next few decades
00:27:40
will probably come up elsewhere the heat
00:27:50
of the Sun is relentless
00:27:52
this is Cameroon in central Africa here
00:27:56
in the streambed of the my abullah River
00:27:58
signs of despair are everywhere
00:28:01
[Music]
00:28:08
the north of Cameroon receives two
00:28:10
months of rainfall a year at most in
00:28:13
August and September during the rest of
00:28:15
the year
00:28:16
people must walk far to find water or
00:28:18
dig deep older people who live here say
00:28:22
that water used to flow abundantly
00:28:23
through the Myo bula river into the
00:28:25
Logan River and eventually discharging
00:28:28
into Lake Chad but those days are gone
00:28:39
[Music]
00:28:42
Edwyn kappa works for the Caritas
00:28:45
charity organization in the region his
00:28:47
job is to ward off looming humanitarian
00:28:49
catastrophes access to drinking water is
00:28:56
an enormous problem for people and
00:28:58
animals here in the far north of
00:29:00
Cameroon

Kadapa often visits villages near the
00:29:12
provincial capital of maroa today he's
00:29:15
in william home to many herders Kadapa
00:29:19
has been a social worker for many years
00:29:21
and knows the signs of an impending
00:29:22
humanitarian catastrophe in the summer
00:29:26
of 2018 the region was on the brink only
00:29:34
women used to fetch water but now it's
00:29:36
so bad the entire family has to help now
00:29:41
when young people want to build a house
00:29:43
they have no water when we want to work
00:29:45
there is no water a young man wants to
00:29:48
be a farmer or work in sales and there's
00:29:51
no water it's already begun
00:29:56
young men are leaving they're going to
00:29:58
the big cities to joan day and Dwolla
00:30:02
people are starting to leave we no
00:30:05
longer know how we will be able to
00:30:07
manage
00:30:12
the drought is especially hard on people
00:30:14
who must find water not just for their
00:30:16
families but also for their livestock
00:30:20
the guy gongfu believes he is about 60
00:30:24
years old and has always tended his
00:30:25
herds now it's so dry that he and his
00:30:29
son John Paul are running out of options
00:30:32
this animal feed was harvested the
00:30:34
previous year by now it's completely
00:30:37
dried out and there isn't much left if
00:30:40
the next month doesn't bring rain the
00:30:43
Colville family fear the worst
00:30:47
if their livestock die they will be left
00:30:50
with nothing
00:31:00
the spring is six kilometers away we
00:31:02
have to fetch water twice a day just to
00:31:04
have barely enough for our four cattle
00:31:06
the goats and my family
00:31:15
don't quibble over the past 10-15 years
00:31:18
the situation has grown much worse
00:31:20
that's why young people aren't able to
00:31:22
stay in their villages they're forced to
00:31:24
leave to go to the cities there's no
00:31:27
future for them here for such a shape as
00:31:29
given away by that video every day
00:31:33
[Music]
00:31:35
young people are moving away because the
00:31:38
lack of water is stealing their futures
00:31:40
herders are having to leave for the
00:31:42
cities because their livestock died of
00:31:44
thirst
00:31:44
traders grain farmers and hunters people
00:31:47
from across northern Cameroon are
00:31:49
leaving their homes they are climate
00:31:51
refugees a sign of things to come but
00:31:59
climate is hardly ever the only reason
00:32:01
behind a decision to migrate poverty is
00:32:04
often a factor fear of terror attacks
00:32:07
can also play a role most of the people
00:32:10
gathered here fled from the Islamist
00:32:12
group Boko Haram in neighboring Nigeria
00:32:16
they are now unintentionally
00:32:18
contributing to the desperate situation
00:32:19
facing local Cameroonians people stand
00:32:26
in line for up to eight hours to receive
00:32:28
a few kilos of food they wait quietly
00:32:30
and patiently despite the brutal heat
00:32:33
there are 200 sacks of millet and corn
00:32:36
for 30 thousand people this help is
00:32:39
urgently needed
00:32:40
but it's only a drop in the bucket
00:32:59
[Applause]
00:33:05
we've already seen several waves of
00:33:08
migration people keep trying to make
00:33:11
their way south to find farmland in
00:33:14
areas where there's more rain many
00:33:17
people have left here heading south here
00:33:32
in the mem a region the rains used to
00:33:34
begin in April now the rains come in
00:33:37
late May sometimes in early June in the
00:33:45
past
00:33:46
it rained until October but last year
00:33:52
the rains ended in August that's a
00:33:58
disaster for us farmers in May so st.
00:34:02
Granada Kapalua Pisa Domini
00:34:05
in order to farm properly soil must
00:34:08
remain moist for at least four months
00:34:10
out of the year experts call this the
00:34:12
120 day line if rain lasts less than
00:34:15
four months soil will grow arid grain
00:34:19
cultivation becomes impossible and
00:34:20
livestock die in the Sahil region this
00:34:26
line between survival and disaster is
00:34:28
moving ever further south toward the
00:34:30
equator where there's more rain from
00:34:32
1970 to 2016 up to 100 kilometre wide
00:34:36
stretches of land that were once arable
00:34:38
have become desert as a result hundreds
00:34:42
of camps have arisen in the Sahil region
00:34:44
filled with people who have lost their
00:34:45
livelihoods temperatures reach 45
00:34:48
degrees Celsius in the shade and 60
00:34:50
degrees in the full Sun people here live
00:34:54
at the edge of despair reliant on food
00:34:56
deliveries from NGOs ISA and Golda and
00:35:02
her family live in one of these camps
00:35:04
they have enough food for now and access
00:35:07
to a water pump but when they fled the
00:35:10
drought they lost their independence
00:35:14
their fields where they used to plant
00:35:17
millet and onions grew arid ISA her
00:35:22
husband and their five children are
00:35:24
climate refugees see we're suffering so
00:35:30
much there's no rain we have no water we
00:35:34
don't have enough water to grow anything
00:35:39
yapple people here heading south hoping
00:35:43
that they'll be able to grow crops there
00:35:44
and find something to eat
00:35:50
in Southeast Asia flooding is driving
00:35:54
people from their homes in Africa
00:35:57
it's the devastating drought Cameroon is
00:36:00
suffering as is neighboring Chad Lake
00:36:04
Chad which lent its name to the entire
00:36:07
region is the only natural source of
00:36:09
water in the area researchers from the
00:36:12
International Organization for Migration
00:36:14
have come to the region surrounding lake
00:36:16
chad to investigate the connection
00:36:18
between climate change and the rise of
00:36:20
climate migration
00:36:30
mushara murillo of the UN migration
00:36:33
organization has spent years in the
00:36:35
Sahil region every encounter and every
00:36:37
conversation adds another layer of
00:36:39
detail to his preliminary findings
00:36:44
[Music]
00:36:49
today Murillo and his team are visiting
00:36:52
a camp for displaced people in their
00:36:54
Lake Chad under the shadow of a nearly
00:36:57
barren tree he speaks with Mohammad
00:36:59
Ibrahim the head of the family Ibrahim
00:37:02
tells Murillo he is a herder the family
00:37:05
suffered a terrible ordeal before
00:37:07
finally arriving at Lake Chad it was
00:37:10
heat and lack of water that drove him
00:37:12
from their home climate change has a
00:37:18
huge impact on us herders if there's no
00:37:20
rain no plants grow and without green
00:37:23
plants to eat our animals die
00:37:25
so we herders are hit very hard by this
00:37:38
from the chat the chat side Nigerian
00:37:41
side the Cameroonian side and either
00:37:42
side they all depended on this source
00:37:45
you can realize that this lake is unique
00:37:48
is just a freshwater with in an arid
00:37:53
area so so many levels
00:37:56
dependent on this lectured if the lake
00:37:59
chad disappears it will be a serious
00:38:02
environmental catastrophe because
00:38:05
without the lectures we can hardly talk
00:38:09
about a living atmosphere in the lake
00:38:11
Chad region
00:38:14
in 1963 lake chad covered an area of
00:38:18
25,000 square kilometres by 2007 it was
00:38:24
just 2,500 square kilometres more than
00:38:27
90 percent smaller and the lake
00:38:29
continues to shrink if the lake were to
00:38:33
completely dry up more than 50 million
00:38:35
people would probably become climate
00:38:37
refugees and this figure does not take
00:38:39
into account the rate of population
00:38:40
growth
00:38:44
lake chad remains a life source for
00:38:47
millions of people but as it continues
00:38:49
to shrink water is becoming an ever
00:38:51
scarce ER and more valuable resource and
00:38:54
so our arable land and the fish in the
00:38:57
lake as Lake Chad gets smaller
00:39:00
competition for these resources will
00:39:02
become increasingly bitter even now
00:39:05
fishermen in the region are competing
00:39:07
for dwindling stocks of carp Nile perch
00:39:10
and tilapia with climate change there is
00:39:14
a key impact on the lake in that it it
00:39:17
affect the distribution and the pattern
00:39:19
of fish and is that in mind its effect
00:39:22
the fishing industry as well so
00:39:24
basically it's it touches on three major
00:39:28
level strategies of people around in
00:39:30
this surrounding this area namely
00:39:32
farmers hair does and fishermen the
00:39:40
region surrounding Lake Chad is
00:39:41
emblematic of the close connection
00:39:43
between climate change and migration
00:39:52
[Applause]
00:40:00
in the past we had a lot of fish good
00:40:02
fish we sold them here or over in
00:40:05
Nigeria but now they have problems with
00:40:07
terrorists and here we have no more fish
00:40:09
in our lake from Lake Chad to Indonesia
00:40:15
farmers can no longer rely on
00:40:17
predictable seasons for planting and
00:40:19
harvesting the climate has become a
00:40:21
threat there are hurricanes cyclones
00:40:24
drought flooding mudslides and wildfires
00:40:27
and the melting permafrost could soon
00:40:30
exacerbate all of those around the globe
00:40:34
on the american continent
00:40:37
people are fleeing droughts in northern
00:40:38
Brazil in the Caribbean and the southern
00:40:41
United States
00:40:42
it's hurricanes in Africa people are
00:40:45
leaving the arid Sahil region some will
00:40:48
likely head north to Europe in Spain
00:40:51
Italy in Greece people will also flee
00:40:54
the rising heat in Asia coastal regions
00:41:00
are vanishing under rising oceans people
00:41:03
are fleeing to higher ground in river
00:41:04
deltas like Bangladesh
00:41:07
the South Sea Islands will be completely
00:41:10
submerged how many people will have
00:41:14
become climate refugees by 2050 we know
00:41:18
at the moment that approximately 20
00:41:20
million people are being displaced every
00:41:22
year
00:41:22
that's numbers more or less true for the
00:41:24
last decades so we can say that under
00:41:26
climate change population growth
00:41:29
possibly more vulnerable populations
00:41:31
this number is going to grow if you look
00:41:33
today we know that every year at least
00:41:36
25 million people flee so the fast
00:41:39
forward 30 years so that's why I think
00:41:42
if you go to the figure 500 millions
00:41:45
it's not a very high estimate seizures
00:41:48
are the names of the do this gee
00:41:51
Monsieur if I had to estimate I'd say
00:41:54
maybe a fifth or a quarter of the
00:41:55
world's population will be forced to
00:41:57
migrate so that's about two to three
00:42:01
billion people
00:42:08
[Music]
00:42:22
you
