1
00:00:06,344 --> 00:00:09,524
Lakes are living creatures.
2
00:00:11,012 --> 00:00:13,342
These precious reserves of water
3
00:00:13,344 --> 00:00:17,104
live and die according to
distinct natural cycles.
4
00:00:20,857 --> 00:00:23,107
Their peaceful waters seem dormant,
5
00:00:23,109 --> 00:00:26,319
yet the teem with mysterious life.
6
00:00:29,541 --> 00:00:31,701
Lakes only reveal themselves to
7
00:00:31,701 --> 00:00:33,581
the men and women who take time to
8
00:00:33,581 --> 00:00:36,781
patiently linger beside their shores.
9
00:00:36,781 --> 00:00:40,671
Together, we are going to
discover their secrets.
10
00:00:52,924 --> 00:00:55,734
Along the shores of Lake Nasser,
11
00:00:55,733 --> 00:00:59,733
Egypt seems eternal and changeless.
12
00:01:02,572 --> 00:01:04,572
Yet, these landscapes are the result
13
00:01:04,569 --> 00:01:06,529
of an enormous upheaval,
14
00:01:06,531 --> 00:01:09,501
that happened barely 50 years ago.
15
00:01:11,117 --> 00:01:14,357
This ancient temple has been moved.
16
00:01:14,785 --> 00:01:17,825
These small islands used to be mountains.
17
00:01:17,966 --> 00:01:20,956
And no boats ever sailed here before.
18
00:01:25,675 --> 00:01:29,005
This vast expanse of water
in the middle of the desert
19
00:01:29,008 --> 00:01:31,138
is actually an artificial lake,
20
00:01:31,144 --> 00:01:34,484
stretching over 500 kilometers long.
21
00:01:35,473 --> 00:01:38,863
A man made lake to meet human needs.
22
00:01:39,850 --> 00:01:43,780
A gigantic experiment that
has transformed Egypt.
23
00:01:45,237 --> 00:01:47,197
What challenges and secrets
24
00:01:47,199 --> 00:01:49,069
are hidden within this lake
25
00:01:49,067 --> 00:01:51,347
that has swallowed up an entire region
26
00:01:51,354 --> 00:01:52,914
and at the same time,
27
00:01:52,911 --> 00:01:55,661
given birth to a new ecosystem.
28
00:02:25,442 --> 00:02:28,532
Lake Nasser is a very young lake.
29
00:02:28,530 --> 00:02:30,820
It was born in the 1960s
30
00:02:30,818 --> 00:02:32,038
after the construction of a
31
00:02:32,037 --> 00:02:35,617
huge hydroelectric dam in Aswan.
32
00:02:38,039 --> 00:02:39,749
Back then, Egyptian president,
33
00:02:39,746 --> 00:02:43,836
Gamal Abdel Nasser, wanted
to modernize his country.
34
00:02:53,759 --> 00:02:55,059
To accomplish this,
35
00:02:55,059 --> 00:02:57,379
he diverted the flow of the Nile,
36
00:02:57,381 --> 00:03:00,051
the second longest river in the world.
37
00:03:04,763 --> 00:03:06,983
Once the Pharaonic work was completed,
38
00:03:06,983 --> 00:03:10,183
the Aswan dam created an enormous lake.
39
00:03:11,453 --> 00:03:13,913
In Egypt, it is called Lake Nasser,
40
00:03:13,914 --> 00:03:16,254
in honor of the president who made it.
41
00:03:16,248 --> 00:03:18,818
In Sudan, it is called Lake Nubia,
42
00:03:18,824 --> 00:03:20,404
named after the region that
43
00:03:20,402 --> 00:03:22,842
vanished beneath it's waters.
44
00:03:24,629 --> 00:03:25,949
When it was created,
45
00:03:25,953 --> 00:03:29,053
Lake Nasser was the biggest
man made lake in the world.
46
00:03:31,665 --> 00:03:33,795
When filled to maximum capacity,
47
00:03:33,801 --> 00:03:35,681
this vast reservoir contains
48
00:03:35,682 --> 00:03:39,232
169 billion cubic meters of water.
49
00:03:39,931 --> 00:03:43,931
A genuine treasure in one of
the driest regions on Earth.
50
00:03:49,393 --> 00:03:51,693
Since it almost never rains in Egypt,
51
00:03:51,692 --> 00:03:53,032
the lakes waters answer
52
00:03:53,034 --> 00:03:55,064
all of the country's needs.
53
00:03:56,692 --> 00:03:58,462
Before the lake was made,
54
00:03:58,456 --> 00:04:01,576
Egypt lived in sync with
the Nile's flood cycle,
55
00:04:01,579 --> 00:04:05,209
which could cause devastating inundations.
56
00:04:11,506 --> 00:04:13,256
Now, the lake and dam
57
00:04:13,259 --> 00:04:16,009
allow Egypt to regulate
the flow of the Nile
58
00:04:16,010 --> 00:04:18,040
and avoid the large-scale damage
59
00:04:18,042 --> 00:04:20,392
caused by seasonal flooding.
60
00:04:21,723 --> 00:04:23,483
It is a strategic water bank
61
00:04:23,476 --> 00:04:25,476
that has created a 30% increase
62
00:04:25,484 --> 00:04:27,484
in fertile land.
63
00:04:28,317 --> 00:04:29,817
Today, farmers can enjoy
64
00:04:29,815 --> 00:04:31,895
two or three harvests a year.
65
00:04:31,897 --> 00:04:34,567
Instead of just one, in the past.
66
00:04:36,409 --> 00:04:38,229
Another benefit of the lake,
67
00:04:38,232 --> 00:04:40,082
is that it enabled Egypt to escape the
68
00:04:40,078 --> 00:04:42,448
major droughts that plagued Africa
69
00:04:42,445 --> 00:04:45,245
in the 1980s and 1990s.
70
00:04:53,801 --> 00:04:55,761
The lake and dam have transformed
71
00:04:55,763 --> 00:04:58,763
the lifestyle of the Egyptian people.
72
00:04:58,758 --> 00:05:00,478
But how has nature adapted
73
00:05:00,477 --> 00:05:02,707
to this major change?
74
00:05:06,108 --> 00:05:07,808
For Egyptian wildlife,
75
00:05:07,814 --> 00:05:10,454
the lake has become a sort of El Dorado.
76
00:05:10,447 --> 00:05:12,817
Fish, birds, and crocodiles
77
00:05:12,818 --> 00:05:14,438
have all made the most
78
00:05:14,443 --> 00:05:16,533
of this new source of life
79
00:05:16,533 --> 00:05:18,413
in the heart of the desert.
80
00:05:23,116 --> 00:05:24,946
A handful of men have been entrusted
81
00:05:24,950 --> 00:05:26,580
to watch over and protect
82
00:05:26,576 --> 00:05:29,036
this immense artificial reservoir.
83
00:05:35,759 --> 00:05:39,589
Haytham Ibrahim is a
ranger and bird specialist.
84
00:05:46,441 --> 00:05:48,651
Professor Gamal El-Shabrawy is an
85
00:05:48,646 --> 00:05:51,806
exert in aquatic plant
life and lake sediment.
86
00:05:53,894 --> 00:05:55,184
Whenever they can,
87
00:05:55,183 --> 00:05:58,143
the two of them survey
the huge expanse of water.
88
00:05:58,144 --> 00:06:00,494
To assess the quality of the environment,
89
00:06:00,489 --> 00:06:01,819
possible changes,
90
00:06:01,824 --> 00:06:04,294
and overall health of the lake.
91
00:06:11,170 --> 00:06:13,700
The lakes ecosystem is
still in its infancy,
92
00:06:13,701 --> 00:06:15,881
in terms of evolution.
93
00:06:15,883 --> 00:06:17,463
Normally, it takes hundreds,
94
00:06:17,462 --> 00:06:19,042
or even millions of years,
95
00:06:19,041 --> 00:06:21,131
to strike a balance.
96
00:06:23,767 --> 00:06:25,467
Lake Nasser is one the first
97
00:06:25,473 --> 00:06:27,983
large-scale man made lakes,
98
00:06:27,981 --> 00:06:29,611
and is a model and benchmark
99
00:06:29,606 --> 00:06:31,936
for those that have followed.
100
00:06:34,391 --> 00:06:36,561
Which species have disappeared,
101
00:06:36,560 --> 00:06:38,150
and which have benefited from
102
00:06:38,151 --> 00:06:40,581
the transformation of a river habitat
103
00:06:40,578 --> 00:06:42,618
into a lake habitat?
104
00:06:49,663 --> 00:06:51,753
This winter, Haytham is trying to count
105
00:06:51,753 --> 00:06:54,553
the number of birds present on the lake.
106
00:06:54,553 --> 00:06:56,793
Even a partial census is important
107
00:06:56,793 --> 00:06:58,343
for measuring the evolution
108
00:06:58,338 --> 00:07:00,868
of this brand new ecosystem.
109
00:07:02,180 --> 00:07:04,510
- After the construction of the high dam,
110
00:07:04,514 --> 00:07:09,514
the habitat change from
a river to be a lake.
111
00:07:09,894 --> 00:07:14,244
So the water begin to fill
112
00:07:14,236 --> 00:07:16,606
all the holes around the area.
113
00:07:16,605 --> 00:07:19,475
And the habitat changed very dramatically.
114
00:07:19,484 --> 00:07:22,534
And this really provide good habitats
115
00:07:22,526 --> 00:07:25,816
for lots of birds.
116
00:07:36,295 --> 00:07:39,085
Birds migrate from Europe,
117
00:07:39,093 --> 00:07:42,183
and they follow specific pass way.
118
00:07:42,182 --> 00:07:44,182
And one of them is
119
00:07:44,179 --> 00:07:47,349
flying over the river Nile to the south.
120
00:07:47,348 --> 00:07:49,438
And Lake Nasser is a fantastic area
121
00:07:49,438 --> 00:07:51,338
for them to rest, to feed,
122
00:07:51,342 --> 00:07:53,682
and then continue their way.
123
00:07:57,902 --> 00:07:58,822
Thanks to the work
124
00:07:58,819 --> 00:08:01,309
of Haytham and volunteer ornithologists,
125
00:08:01,313 --> 00:08:03,823
over 130 species of birds
126
00:08:03,823 --> 00:08:06,583
have been recorded on the lake.
127
00:08:07,248 --> 00:08:09,908
The arrival of migratory birds in winter
128
00:08:09,906 --> 00:08:13,416
coincides with a seasonal
drop in water level.
129
00:08:13,749 --> 00:08:16,279
The lower waters, reveal many insects,
130
00:08:16,280 --> 00:08:18,630
and larvae that they feed on.
131
00:08:20,460 --> 00:08:21,590
- But some of them
132
00:08:21,586 --> 00:08:23,786
like to spend the winter over here.
133
00:08:23,792 --> 00:08:25,012
But they don't breed.
134
00:08:25,005 --> 00:08:26,045
They spend the winter,
135
00:08:26,049 --> 00:08:27,769
and then return back to Europe.
136
00:08:27,768 --> 00:08:32,258
Like ducks species,
region shoveler, teals.
137
00:08:32,263 --> 00:08:34,023
Also the waders.
138
00:08:34,015 --> 00:08:35,695
Lake tends to cultivate,
139
00:08:35,695 --> 00:08:37,635
common sandpiper,
140
00:08:37,643 --> 00:08:39,603
wood sandpipers.
141
00:08:43,402 --> 00:08:45,702
So Lake Nasser is very important.
142
00:08:45,700 --> 00:08:47,620
Not only for the wintering species,
143
00:08:47,616 --> 00:08:50,616
but also for the summer visitors
144
00:08:50,623 --> 00:08:53,163
that came from Africa to the north.
145
00:08:54,582 --> 00:08:56,422
Like the
pink-backed pelican,
146
00:08:56,416 --> 00:08:59,936
which has taken up residency
here more permanently.
147
00:08:59,944 --> 00:09:03,134
Or even the African pied wagtail,
148
00:09:03,127 --> 00:09:05,007
which has settled in little by little,
149
00:09:05,008 --> 00:09:07,498
and now breeds on the lake.
150
00:09:22,654 --> 00:09:25,184
The results Haytham has
observed in the field
151
00:09:25,183 --> 00:09:27,663
tend to show that certain endemic species,
152
00:09:27,658 --> 00:09:29,538
such as the Egyptian goose,
153
00:09:29,538 --> 00:09:30,488
which was endangered
154
00:09:30,490 --> 00:09:32,440
before the lake was created,
155
00:09:32,441 --> 00:09:36,131
have greatly benefited
from this new environment.
156
00:09:38,292 --> 00:09:40,052
- The long-eared owl is
now is increasing and
157
00:09:40,048 --> 00:09:43,038
adapting very well, feeding on the lake,
158
00:09:43,043 --> 00:09:44,513
and this is one of the good things
159
00:09:44,506 --> 00:09:46,796
which Lake Nasser do for birds.
160
00:09:53,388 --> 00:09:55,258
The healthy
evolution of the lake
161
00:09:55,257 --> 00:09:57,097
is also a constant concern for
162
00:09:57,103 --> 00:09:59,733
biologist Gamal El-Shabrawy,
163
00:09:59,727 --> 00:10:01,807
aquatic plant expert.
164
00:10:09,572 --> 00:10:11,372
This morning, he's heading off
165
00:10:11,371 --> 00:10:12,741
in search of macrophytes,
166
00:10:12,741 --> 00:10:15,211
one of his favorite subjects.
167
00:10:15,656 --> 00:10:16,996
The term macrophyte,
168
00:10:17,002 --> 00:10:19,052
refers to all large water plants
169
00:10:19,046 --> 00:10:21,246
that can be seen with the naked eye.
170
00:10:21,251 --> 00:10:24,171
They're a good gauge of a healthy lake.
171
00:10:43,391 --> 00:10:45,691
- Ah, yes.
172
00:10:45,690 --> 00:10:47,610
These are macrophytes.
173
00:10:47,606 --> 00:10:49,806
Macrophytes are aquatic plants
174
00:10:49,814 --> 00:10:51,574
considered to be the keystone
175
00:10:51,565 --> 00:10:54,445
of any aquatic system.
176
00:10:56,128 --> 00:10:57,528
These underwater plants
177
00:10:57,532 --> 00:10:59,042
produce oxygen,
178
00:10:59,042 --> 00:11:01,712
and make up a particularly
favorable environment
179
00:11:01,712 --> 00:11:04,882
for the development of
numerous fish species.
180
00:11:06,994 --> 00:11:09,794
Here, they're not seaweed, but plants,
181
00:11:09,792 --> 00:11:12,892
with roots, stems, and flowers.
182
00:11:14,506 --> 00:11:17,346
- Plant eating fish reproduce
183
00:11:17,351 --> 00:11:20,471
and grow among these aquatic plants.
184
00:11:20,474 --> 00:11:22,134
Here on Lake Nasser,
185
00:11:22,134 --> 00:11:25,144
tilapia feed on macrophytes.
186
00:11:26,569 --> 00:11:28,649
- And tilapia constitute more than
187
00:11:28,647 --> 00:11:31,487
90% of the fish living in the lake.
188
00:11:34,034 --> 00:11:35,244
The abundance of this
189
00:11:35,242 --> 00:11:37,292
type of macrophyte in Lake Nasser,
190
00:11:37,285 --> 00:11:39,955
means the water is not polluted
191
00:11:39,958 --> 00:11:41,708
For Dr. El-Shabrawy,
192
00:11:41,711 --> 00:11:43,241
it's a reliable indicator that
193
00:11:43,244 --> 00:11:45,554
the lake is in good health.
194
00:11:46,123 --> 00:11:47,513
- You know, there are bad
195
00:11:47,505 --> 00:11:50,545
and there are good macrophytes.
196
00:11:50,547 --> 00:11:52,667
The bad macrophytes cover
197
00:11:52,671 --> 00:11:55,551
a very wide area of the lake.
198
00:11:55,550 --> 00:11:57,690
And they prevent oxygen
199
00:11:57,686 --> 00:12:01,176
from getting into the water.
200
00:12:01,181 --> 00:12:03,471
You can find bad macrophytes
201
00:12:03,468 --> 00:12:06,438
before and after Lake Nasser.
202
00:12:06,440 --> 00:12:07,560
And we're lucky because
203
00:12:07,555 --> 00:12:09,725
we don't find them here.
204
00:12:13,023 --> 00:12:16,243
All these
macrophytes grow in cores.
205
00:12:16,244 --> 00:12:19,624
In Arabic, core means "dry river."
206
00:12:20,660 --> 00:12:22,750
Before Lake Nasser was created,
207
00:12:22,750 --> 00:12:25,580
that's exactly what these valleys were.
208
00:12:25,582 --> 00:12:27,802
Canyons, gouged out by rivers,
209
00:12:27,800 --> 00:12:30,420
millions of years ago.
210
00:12:34,638 --> 00:12:37,798
Today, the cores are filled
with the lake's waters.
211
00:12:37,798 --> 00:12:40,178
And one can boat on them
212
00:12:40,933 --> 00:12:43,563
From the sky, they look like fractals,
213
00:12:43,557 --> 00:12:46,877
branching across the
surface of the desert.
214
00:12:50,030 --> 00:12:52,410
The lace-like geography of the cores
215
00:12:52,406 --> 00:12:54,366
has created thousands of kilometers
216
00:12:54,368 --> 00:12:56,108
of river coastline.
217
00:12:56,109 --> 00:12:58,569
About 740, which varies,
218
00:12:58,571 --> 00:13:01,411
according the flood level each year.
219
00:13:05,037 --> 00:13:08,027
It's a blessing for the fish
that feed on macrophytes.
220
00:13:08,032 --> 00:13:10,722
As well as for a brand
new fishing industry
221
00:13:10,715 --> 00:13:13,005
that didn't exist before.
222
00:13:21,477 --> 00:13:23,347
Six to ten thousand fishermen
223
00:13:23,346 --> 00:13:26,686
are estimated to work on the lake today.
224
00:13:27,062 --> 00:13:28,692
Before the dam was built,
225
00:13:28,687 --> 00:13:31,687
there were only a few hundred of them.
226
00:13:32,439 --> 00:13:36,399
They come from Faiyum, the
delta, or middle Egypt.
227
00:13:37,071 --> 00:13:40,031
Hardly any are from around here.
228
00:13:41,158 --> 00:13:43,488
Many of the live in temporary camps,
229
00:13:43,491 --> 00:13:46,341
on islets, or along the shores.
230
00:13:46,336 --> 00:13:47,876
They stay three to six months,
231
00:13:47,880 --> 00:13:49,960
before returning to visit their families
232
00:13:49,958 --> 00:13:51,578
a few weeks,
233
00:13:51,583 --> 00:13:53,633
and then coming back.
234
00:13:54,010 --> 00:13:55,140
The creation of the lake
235
00:13:55,136 --> 00:13:58,126
has not only changed the
lives of these fishermen.
236
00:13:58,132 --> 00:13:59,512
It has also radically altered
237
00:13:59,513 --> 00:14:02,173
those of countless types of fish.
238
00:14:02,171 --> 00:14:04,711
Some have adapted and multiplied,
239
00:14:04,714 --> 00:14:06,974
while others have dwindled.
240
00:14:12,238 --> 00:14:14,818
Tilapia make up most of the catch.
241
00:14:14,815 --> 00:14:16,775
It is the species that has most benefited
242
00:14:16,777 --> 00:14:18,897
from the transformation of a river habitat
243
00:14:18,902 --> 00:14:21,582
into a lake habitat.
244
00:14:22,199 --> 00:14:23,819
We also find other types,
245
00:14:23,824 --> 00:14:25,374
like the bottle nose fish,
246
00:14:25,369 --> 00:14:26,829
or the Nile carp.
247
00:14:26,831 --> 00:14:29,361
But they remain in the minority.
248
00:14:30,563 --> 00:14:33,183
Tiger fish, which used to be plentiful
249
00:14:33,175 --> 00:14:35,165
in the flowing waters of the Nile,
250
00:14:35,172 --> 00:14:37,342
have practically disappeared.
251
00:14:39,131 --> 00:14:40,721
These predatory fish,
252
00:14:40,722 --> 00:14:42,302
like the Nile perch as well,
253
00:14:42,301 --> 00:14:45,261
have great commercial value.
254
00:14:45,261 --> 00:14:47,021
They've suffered from over-fishing
255
00:14:47,016 --> 00:14:49,806
and the change in their aquatic habitat.
256
00:15:07,834 --> 00:15:10,464
Most fishermen work in the cores,
257
00:15:10,460 --> 00:15:12,120
but some also cast their nets
258
00:15:12,120 --> 00:15:13,760
in the deep waters in the middle
259
00:15:13,757 --> 00:15:15,877
of the lake at sundown.
260
00:15:15,882 --> 00:15:19,422
At dawn, they pull them
up with their catch.
261
00:15:44,315 --> 00:15:46,575
These fish are dried, salted, and sold,
262
00:15:46,578 --> 00:15:49,198
exclusively in Egypt.
263
00:16:06,768 --> 00:16:08,598
There are now three small ports
264
00:16:08,603 --> 00:16:10,553
on the western coast of the lake,
265
00:16:10,553 --> 00:16:13,943
Aswan, Gerf Hussein, and Abu Simbel.
266
00:16:14,942 --> 00:16:16,892
Fishermen come to deliver their catch
267
00:16:16,892 --> 00:16:19,022
or stock up on ice.
268
00:16:49,470 --> 00:16:51,510
When they are too far from port,
269
00:16:51,513 --> 00:16:54,393
some fishermen give their
fish to a fridge boat,
270
00:16:54,392 --> 00:16:57,282
that comes to collect their catch.
271
00:16:59,779 --> 00:17:02,449
After an auspicious period in the 1980s,
272
00:17:02,450 --> 00:17:04,190
the number of fish caught today
273
00:17:04,191 --> 00:17:06,361
falls short of what was expected.
274
00:17:06,363 --> 00:17:07,913
According to experts,
275
00:17:07,907 --> 00:17:10,617
almost half of the fish are missing.
276
00:17:12,528 --> 00:17:14,368
- Today's our seventh day out,
277
00:17:14,373 --> 00:17:17,533
and we've barely collected one ton.
278
00:17:17,532 --> 00:17:18,382
The zone we're covering
279
00:17:18,379 --> 00:17:20,379
doesn't contain many fish,
280
00:17:20,376 --> 00:17:22,046
and fishermen are catching fewer
281
00:17:22,048 --> 00:17:25,578
and fewer of them.
282
00:17:29,095 --> 00:17:31,885
Before, the fish were a lot bigger,
283
00:17:31,893 --> 00:17:33,393
but now, fishermen are using nets
284
00:17:33,391 --> 00:17:36,851
with finer mesh to catch smaller fish.
285
00:17:36,850 --> 00:17:40,280
That has obviously cause
a reduction in fish.
286
00:17:55,868 --> 00:17:57,168
Haytham Ibrahim
287
00:17:57,168 --> 00:17:58,958
and Dr. Gamal El-Shabrawy
288
00:17:58,956 --> 00:18:01,836
continue their inspection of the lake.
289
00:18:03,913 --> 00:18:05,213
They now arrive within sight
290
00:18:05,214 --> 00:18:07,874
of the Al-Madiq Gorge.
291
00:18:07,871 --> 00:18:09,921
It's the narrowest part of the lake,
292
00:18:09,919 --> 00:18:12,719
Less than one kilometer wide.
293
00:18:17,393 --> 00:18:20,323
- Egyptian engineers
has originally planned
294
00:18:20,319 --> 00:18:23,439
that they would build the dam here.
295
00:18:23,442 --> 00:18:26,452
but they then realized
that most of the water
296
00:18:26,449 --> 00:18:29,699
would be in Sudan and not in Egypt.
297
00:18:29,700 --> 00:18:31,410
For this reason,
298
00:18:31,406 --> 00:18:34,036
they built the high dam in Aswan.
299
00:18:48,496 --> 00:18:50,046
Construction
of the Aswan dam
300
00:18:50,052 --> 00:18:53,522
began in 1960.
301
00:18:54,975 --> 00:18:58,005
In all, over 36,000 Egyptian workers
302
00:18:58,005 --> 00:19:00,315
worked tirelessly, day and night.
303
00:19:00,315 --> 00:19:02,935
Sometimes, in unbearable heat.
304
00:19:02,939 --> 00:19:04,519
In the summer, it frequently hits
305
00:19:04,518 --> 00:19:07,568
45 degrees centigrade in the shade.
306
00:19:11,937 --> 00:19:15,997
This gigantic building
project lasted ten years.
307
00:19:19,124 --> 00:19:20,754
At the time, this pharaonic challenge
308
00:19:20,749 --> 00:19:24,779
was considered a victory of silent nature.
309
00:19:29,793 --> 00:19:31,553
A victory that allowed Egypt to
310
00:19:31,546 --> 00:19:34,216
achieve energy independence.
311
00:19:36,353 --> 00:19:38,563
With 2.1 gigawatts of power,
312
00:19:38,559 --> 00:19:40,769
equivalent to a nuclear reactor,
313
00:19:40,765 --> 00:19:42,265
the hydroelectric plant has
314
00:19:42,274 --> 00:19:44,944
brought light to cities and villages.
315
00:19:46,523 --> 00:19:50,333
New industries have
developed along the Nile.
316
00:19:53,071 --> 00:19:54,911
Up until the 1980s,
317
00:19:54,905 --> 00:19:56,575
the dam provided over half
318
00:19:56,577 --> 00:19:58,997
of the country's electricity.
319
00:19:59,944 --> 00:20:02,214
Today, demand has increased,
320
00:20:02,208 --> 00:20:05,948
and it now only provides 25%.
321
00:20:06,632 --> 00:20:09,302
- When the dam was built,
322
00:20:09,302 --> 00:20:10,542
Egypt's population was only
323
00:20:10,544 --> 00:20:13,864
25 - 30 million.
324
00:20:13,857 --> 00:20:16,217
Now, there are 90 million of us.
325
00:20:16,215 --> 00:20:19,135
So, obviously consumption has increased.
326
00:20:21,730 --> 00:20:23,650
Progress
and industrialization
327
00:20:23,646 --> 00:20:26,686
did not come without a cost.
328
00:20:28,475 --> 00:20:31,475
Once the dam was completed in 1970,
329
00:20:31,482 --> 00:20:33,482
Lake Nasser began to fill,
330
00:20:33,479 --> 00:20:35,619
flooding the entire Nile valley,
331
00:20:35,616 --> 00:20:38,616
between Aswan and northern Sudan.
332
00:20:53,135 --> 00:20:55,305
An entire region, Nubia,
333
00:20:55,306 --> 00:20:57,216
and it's ancestral culture,
334
00:20:57,222 --> 00:20:58,982
was engulfed beneath the waters,
335
00:20:58,975 --> 00:21:01,885
like a modern day Atlantis.
336
00:21:06,684 --> 00:21:10,534
At the time, over 100,000
Nubians were relocated
337
00:21:10,527 --> 00:21:12,897
to temporary accommodations in the desert,
338
00:21:12,895 --> 00:21:15,475
far from the Nile.
339
00:21:15,983 --> 00:21:18,333
Hundreds of thousands of date palms,
340
00:21:18,329 --> 00:21:20,329
their resource and treasure,
341
00:21:20,326 --> 00:21:24,286
disappeared forever.
342
00:21:39,842 --> 00:21:41,562
After years of exile,
343
00:21:41,560 --> 00:21:45,220
a few Nubians have begun
to resettle along the lake.
344
00:21:45,728 --> 00:21:47,558
Fekry Kashef, for example,
345
00:21:47,563 --> 00:21:50,523
came back to live near
the temple of Abu Simbel,
346
00:21:50,523 --> 00:21:52,403
where he worked as a guide.
347
00:21:56,769 --> 00:21:59,729
Here, he has recreated
the Eden of his childhood,
348
00:21:59,730 --> 00:22:01,270
as he remembers it before his
349
00:22:01,274 --> 00:22:04,414
entire family had to leave.
350
00:22:07,412 --> 00:22:09,502
He built a traditional home,
351
00:22:09,501 --> 00:22:11,711
an authentic hub of life and memory
352
00:22:11,707 --> 00:22:14,037
for his community.
353
00:22:35,148 --> 00:22:36,698
Here, Fekry and his friends
354
00:22:36,696 --> 00:22:40,906
continue to keep the
traditional Nubian songs alive.
355
00:22:42,780 --> 00:22:45,660
Together, they remember
the loss of their country,
356
00:22:45,659 --> 00:22:47,489
and how the course of their lives
357
00:22:47,493 --> 00:22:50,213
was changed along with Egypts.
358
00:22:59,138 --> 00:23:00,788
Dozens of Egyptian temples
359
00:23:00,787 --> 00:23:01,927
built along the Nile
360
00:23:01,925 --> 00:23:03,845
over three thousand years ago,
361
00:23:03,852 --> 00:23:06,812
also risked vanishing completely.
362
00:23:10,133 --> 00:23:12,823
Unesco took emergency action.
363
00:23:12,815 --> 00:23:15,305
Launching an appeal to the
international community,
364
00:23:15,311 --> 00:23:18,151
to salvage the most important ones.
365
00:23:21,940 --> 00:23:23,790
Some 50 countries took part
366
00:23:23,786 --> 00:23:25,786
in this astonishing rescue mission,
367
00:23:25,785 --> 00:23:29,115
which lasted over 10 years.
368
00:23:29,918 --> 00:23:32,828
This explains how the two
temples at Abu Simbel,
369
00:23:32,832 --> 00:23:36,262
that of Ramesses II and
his wife, Nefertari,
370
00:23:36,257 --> 00:23:40,177
were dismantled and
rebuilt 64 meters uphill.
371
00:23:42,967 --> 00:23:46,137
- Here the two temples of Abu Simbel
372
00:23:46,137 --> 00:23:50,187
we entirely carved into
the rock in sandstone.
373
00:23:50,189 --> 00:23:51,889
Unesco did something which was their
374
00:23:51,885 --> 00:23:54,275
most enormous undertaking ever,
375
00:23:54,275 --> 00:23:56,935
they cut the two temples into blocks.
376
00:23:59,105 --> 00:24:02,015
The pillars
were cut with very fine saws,
377
00:24:02,019 --> 00:24:04,409
in the utmost of care.
378
00:24:04,411 --> 00:24:06,111
The stone is so fragile,
379
00:24:06,106 --> 00:24:07,946
that the mere contact with water
380
00:24:07,952 --> 00:24:10,622
could turn it into dust.
381
00:24:11,331 --> 00:24:14,131
- The big temple was
cut into 1,200 blocks,
382
00:24:14,129 --> 00:24:18,709
and Nefertari's temple into 450.
383
00:24:18,714 --> 00:24:22,304
In total, there was 1650 blocks,
384
00:24:22,302 --> 00:24:26,262
weighing between 10 and 33 tons.
385
00:24:26,261 --> 00:24:28,511
The blocks of crumbly sandstone,
386
00:24:28,513 --> 00:24:31,393
were injected with synthetic resin,
387
00:24:31,393 --> 00:24:33,853
to strengthen them.
388
00:24:37,488 --> 00:24:40,178
Ramesses
II has his face amputated
389
00:24:40,184 --> 00:24:42,374
and taken to a storage zone.
390
00:24:48,200 --> 00:24:51,130
The distinctive rocky
landscape around the temples
391
00:24:51,126 --> 00:24:54,746
had to be rebuilt exactly as it had been.
392
00:24:57,674 --> 00:24:59,174
In a modern exploit,
393
00:24:59,171 --> 00:25:01,461
the temples at Abu Simbel were thus moved
394
00:25:01,459 --> 00:25:03,419
safely, and without harm,
395
00:25:03,421 --> 00:25:06,101
down to the last piece.
396
00:25:07,264 --> 00:25:09,304
Until the 20 meter tall giants,
397
00:25:09,295 --> 00:25:12,465
were able to be reassembled.
398
00:25:23,111 --> 00:25:24,661
The waters of Lake Nasser
399
00:25:24,655 --> 00:25:25,765
threatened these monuments
400
00:25:25,770 --> 00:25:27,600
of humanity's heritage.
401
00:25:27,604 --> 00:25:29,374
But international solidarity
402
00:25:29,369 --> 00:25:31,539
managed to save Abu SImbel,
403
00:25:31,540 --> 00:25:35,170
along with about 20 other
of the most important ones.
404
00:25:42,802 --> 00:25:44,012
At the same time,
405
00:25:44,009 --> 00:25:46,509
another emblematic
figure of ancient Egypt,
406
00:25:46,513 --> 00:25:49,723
was making the most of
this new aquatic world.
407
00:25:54,814 --> 00:25:56,864
Before the creation of Lake Nasser,
408
00:25:56,858 --> 00:25:59,778
crocodiles were endangered in Egypt.
409
00:26:01,815 --> 00:26:04,565
The abundant fish, calm waters,
410
00:26:04,567 --> 00:26:07,447
and the lace-like geography of the cores
411
00:26:07,450 --> 00:26:09,570
have given them the perfect environment
412
00:26:09,574 --> 00:26:12,584
in which to thrive once more.
413
00:26:12,953 --> 00:26:16,503
The lake literally saved the species.
414
00:26:24,168 --> 00:26:25,668
Fishermen, however,
415
00:26:25,666 --> 00:26:27,296
aren't necessarily thrilled
416
00:26:27,303 --> 00:26:29,303
at the demographic boom that's happened
417
00:26:29,300 --> 00:26:31,640
over the past two decades.
418
00:26:33,015 --> 00:26:34,635
Currently, the crocodile population
419
00:26:34,640 --> 00:26:38,980
is estimated at between 15,000 - 20,000.
420
00:26:47,992 --> 00:26:52,712
- We hunt crocodiles with
a big fish on a hook.
421
00:26:52,705 --> 00:26:55,485
Then we put a piece of wood in it's mouth,
422
00:26:55,492 --> 00:26:57,952
and tie it, with a rope.
423
00:26:57,953 --> 00:27:00,833
That way, it's teeth sink in the wood
424
00:27:00,832 --> 00:27:03,622
and it can't open it's jaw.
425
00:27:03,619 --> 00:27:07,159
After that, we pull it ashore.
426
00:27:07,160 --> 00:27:10,210
We take it's skin to sell to merchants
427
00:27:10,213 --> 00:27:14,233
who pay 12 or 13 euros.
428
00:27:14,225 --> 00:27:17,845
The skins are used to make bags and shoes.
429
00:27:20,506 --> 00:27:22,026
The crocodiles and fishermen
430
00:27:22,027 --> 00:27:24,007
settle in the same spots.
431
00:27:24,013 --> 00:27:26,613
Where the most fish are found.
432
00:27:26,985 --> 00:27:29,605
Inevitably, things get a little tense
433
00:27:29,609 --> 00:27:32,029
between the competing predators.
434
00:27:34,647 --> 00:27:38,197
- If we cast our nets
along the shore at night,
435
00:27:38,200 --> 00:27:40,450
the crocodiles get caught in them,
436
00:27:40,452 --> 00:27:43,922
and completely tear them apart.
437
00:27:44,632 --> 00:27:48,012
That's why we hunt them.
438
00:27:48,010 --> 00:27:51,680
People hunt them because
they're really dangerous.
439
00:27:51,679 --> 00:27:53,219
If they attack someone,
440
00:27:53,223 --> 00:27:55,343
they kill and eat him.
441
00:27:55,336 --> 00:27:56,876
They also attack our livestock
442
00:27:56,880 --> 00:28:00,340
when they go near the shore.
443
00:28:00,340 --> 00:28:03,190
They're not our friends.
444
00:28:05,936 --> 00:28:07,896
Back in
ancient Egypt, however,
445
00:28:07,898 --> 00:28:10,358
Crocodiles were venerated.
446
00:28:10,360 --> 00:28:13,030
Entire temples were even devoted to them.
447
00:28:13,030 --> 00:28:14,860
Like the Temple of Kom Ombo,
448
00:28:14,864 --> 00:28:18,254
located a few kilometers
north of the lake.
449
00:28:22,747 --> 00:28:24,697
The crocodile god, Sobek,
450
00:28:24,698 --> 00:28:26,998
was intimately linked to the Nile,
451
00:28:26,999 --> 00:28:30,009
and Egypt's prosperity.
452
00:28:38,850 --> 00:28:41,180
- The god, Sobek, was
one of the most important
453
00:28:41,184 --> 00:28:44,354
Egyptian deities in all of it's pantheon.
454
00:28:44,354 --> 00:28:46,304
He was noted for many things,
455
00:28:46,304 --> 00:28:47,644
but chief amongst them,
456
00:28:47,639 --> 00:28:49,779
was the fact that he was a solar god,
457
00:28:49,775 --> 00:28:51,155
god of the sun.
458
00:28:51,157 --> 00:28:53,437
He was also associated with water,
459
00:28:53,444 --> 00:28:54,834
the inundation,
460
00:28:54,826 --> 00:28:57,316
and therefore, he was
important for fertility,
461
00:28:57,322 --> 00:28:59,252
and, in particular, agriculture,
462
00:28:59,249 --> 00:29:01,489
because you need both
the water and the sun
463
00:29:01,490 --> 00:29:03,830
to make your crops flourish.
464
00:29:07,585 --> 00:29:09,335
The
association with the sun,
465
00:29:09,338 --> 00:29:11,798
no doubt came from the sight of crocodiles
466
00:29:11,800 --> 00:29:15,290
basking along the banks of the Nile.
467
00:29:18,755 --> 00:29:21,255
Like all reptiles, they constantly need
468
00:29:21,262 --> 00:29:24,682
to warm themselves in
the sun's bright rays.
469
00:29:28,065 --> 00:29:30,855
- Sobek was worshiped,
not just as a statue,
470
00:29:30,863 --> 00:29:32,653
but also as a living god.
471
00:29:32,651 --> 00:29:34,741
Here in this pool at Kom Ombo,
472
00:29:34,741 --> 00:29:37,661
he was kept as a living crocodile.
473
00:29:37,655 --> 00:29:40,155
And the priests of Sobek were very happy
474
00:29:40,163 --> 00:29:41,613
to take care of him,
475
00:29:41,614 --> 00:29:43,334
because he would be fed,
476
00:29:43,332 --> 00:29:45,452
he would be given sweet meats,
477
00:29:45,445 --> 00:29:47,785
he would be sung too,
478
00:29:47,790 --> 00:29:49,880
he would be, perhaps, even massaged,
479
00:29:49,880 --> 00:29:52,840
and he also was given
beautiful earrings of gold
480
00:29:52,841 --> 00:29:55,051
and also bracelets of gold,
481
00:29:55,047 --> 00:29:57,677
so he shown like the sun.
482
00:30:05,846 --> 00:30:07,016
Ancient Egyptians believed
483
00:30:07,017 --> 00:30:10,107
crocodiles had divinitory powers.
484
00:30:10,929 --> 00:30:12,229
They remarked that the creatures
485
00:30:12,230 --> 00:30:13,860
could predict how high the Nile
486
00:30:13,855 --> 00:30:16,385
would rise during the flood.
487
00:30:20,438 --> 00:30:22,908
- Female crocodiles would lay their eggs
488
00:30:22,911 --> 00:30:26,211
at specific points along
the bank of the Nile,
489
00:30:26,208 --> 00:30:27,828
and, in fact,
490
00:30:27,833 --> 00:30:30,003
they knew before the flood happened,
491
00:30:30,004 --> 00:30:31,764
where it would come.
492
00:30:31,757 --> 00:30:34,047
So they could predict
the height of the flood
493
00:30:34,045 --> 00:30:37,675
and their nests would always
be a little bit higher.
494
00:30:37,679 --> 00:30:39,419
So by looking at where crocodiles
495
00:30:39,420 --> 00:30:41,010
were making their nests,
496
00:30:41,011 --> 00:30:43,021
the ancient Egyptians were, in fact,
497
00:30:43,019 --> 00:30:46,179
able to judge the height of the flood.
498
00:30:47,106 --> 00:30:48,596
The temple
of the god, Sobek,
499
00:30:48,604 --> 00:30:51,904
was very important in ancient Egypt.
500
00:30:51,901 --> 00:30:55,401
Pilgrims would come from
far away to be healed here.
501
00:30:55,401 --> 00:30:57,151
- They would use crocodiles,
502
00:30:57,154 --> 00:30:59,124
particularly for medicine,
503
00:30:59,116 --> 00:31:01,226
so you would have the fat,
504
00:31:01,229 --> 00:31:03,189
and the dung, and the oil,
505
00:31:03,191 --> 00:31:04,991
all used for different things,
506
00:31:04,991 --> 00:31:06,871
in fact, crocodile fat,
507
00:31:06,872 --> 00:31:08,242
when rubbed on the hair,
508
00:31:08,241 --> 00:31:10,961
was supposed to be a cure for baldness.
509
00:31:10,958 --> 00:31:13,998
And, every bit of the
crocodile was useful.
510
00:31:14,000 --> 00:31:16,710
Even the penis, because
some of the penises were
511
00:31:16,705 --> 00:31:18,695
as much as one meter long,
512
00:31:18,703 --> 00:31:21,513
so of course this was a
symbol of male virility.
513
00:31:21,514 --> 00:31:25,684
And, even today, in some of
the more folkloric customs,
514
00:31:25,682 --> 00:31:28,192
pieces of crocodile penis are cut off,
515
00:31:28,190 --> 00:31:30,850
ground up, and mixed with black honey,
516
00:31:30,848 --> 00:31:32,278
and then men eat it so they
517
00:31:32,276 --> 00:31:35,476
can become very very strong.
518
00:31:42,203 --> 00:31:44,363
Once the sacred crocodile had died,
519
00:31:44,362 --> 00:31:47,082
the priests would very
carefully mummify the crocodile,
520
00:31:47,079 --> 00:31:49,539
and either bury it in a catacomb,
521
00:31:49,540 --> 00:31:52,530
or else, even in the temples.
522
00:31:53,708 --> 00:31:56,218
These mummies have been
found by archaeologists,
523
00:31:56,216 --> 00:31:58,546
numbering the hundreds of thousands,
524
00:31:58,550 --> 00:32:00,080
and these are very useful tools
525
00:32:00,084 --> 00:32:02,524
to understand the crocodile cult.
526
00:32:03,681 --> 00:32:05,731
More than 2,000 years later,
527
00:32:05,725 --> 00:32:07,005
these mummies have led to a
528
00:32:07,013 --> 00:32:09,603
fascinating scientific discovery.
529
00:32:10,299 --> 00:32:11,679
- Scientists have analyzed the
530
00:32:11,681 --> 00:32:14,531
mitochondrial DNA of crocodile mummies,
531
00:32:14,525 --> 00:32:17,565
as well as of live crocodile populations,
532
00:32:17,567 --> 00:32:19,817
and they have found
that there are actually
533
00:32:19,819 --> 00:32:22,279
two different kind of crocodiles
534
00:32:22,281 --> 00:32:23,701
found in Egypt.
535
00:32:23,697 --> 00:32:25,867
One is the crocodylus niloticus,
536
00:32:25,868 --> 00:32:28,408
and the other one is
the crocodylus suchus.
537
00:32:28,411 --> 00:32:30,991
And, it's very interesting, because,
538
00:32:30,988 --> 00:32:34,798
the suchus is a much
calmer kind of animal.
539
00:32:34,796 --> 00:32:36,166
It isn't as fierce.
540
00:32:36,166 --> 00:32:38,126
It isn't as nasty.
541
00:32:38,128 --> 00:32:40,748
Although, it looks just
like the other one.
542
00:32:40,752 --> 00:32:42,542
This means, probably,
543
00:32:42,540 --> 00:32:44,760
that the priests of ancient Egypt
544
00:32:44,758 --> 00:32:46,688
would have kept the suchus
545
00:32:46,685 --> 00:32:48,305
in the ponds in the temple,
546
00:32:48,310 --> 00:32:50,420
because it was less likely to attack
547
00:32:50,423 --> 00:32:53,153
and savage them, as well as the visitors.
548
00:32:54,684 --> 00:32:55,864
This study has shown
549
00:32:55,857 --> 00:32:59,147
that the suchus crocodile,
highly present in west Africa,
550
00:32:59,154 --> 00:33:02,284
no longer exists along the Nile.
551
00:33:03,775 --> 00:33:05,845
Today, all we find in Lake Nasser
552
00:33:05,853 --> 00:33:08,523
are the more aggresive
and endemic variety,
553
00:33:08,523 --> 00:33:11,543
the crocodylus niloticus.
554
00:33:12,668 --> 00:33:14,828
- It is quite possible, based on
555
00:33:14,828 --> 00:33:17,128
the scholarly findings of the DNA,
556
00:33:17,126 --> 00:33:19,536
that the crocodiles that
were worshiped in Egypt,
557
00:33:19,541 --> 00:33:22,131
actually were not native to the country,
558
00:33:22,130 --> 00:33:25,060
but were instead brought
in from west Africa,
559
00:33:25,056 --> 00:33:29,846
maybe as gifts, or maybe as
special imports for the gods.
560
00:33:35,934 --> 00:33:38,024
Perhaps
these sacred crocodiles
561
00:33:38,024 --> 00:33:41,324
were offered to the
Pharaoh by an African king,
562
00:33:41,321 --> 00:33:42,871
but for the time being,
563
00:33:42,865 --> 00:33:45,105
no archaeological clues have been found
564
00:33:45,106 --> 00:33:48,066
to back up this hypothesis.
565
00:33:56,031 --> 00:33:58,831
Nubians perpetuated the
cult of the crocodile,
566
00:33:58,829 --> 00:34:02,759
and have maintained powerful
ties with the animal.
567
00:34:03,636 --> 00:34:06,786
It's not rare to see a
stuffed or painted crocodile
568
00:34:06,794 --> 00:34:09,344
on the front of their homes.
569
00:34:10,346 --> 00:34:12,966
For them, it acts as a protective symbol,
570
00:34:12,970 --> 00:34:15,810
and a sign of prestige.
571
00:34:17,974 --> 00:34:19,894
Some of them even keep live crocodiles
572
00:34:19,890 --> 00:34:23,320
in their homes for good luck.
573
00:34:25,532 --> 00:34:28,112
This traditional practice is illegal,
574
00:34:28,110 --> 00:34:31,950
since the Nile crocodile
is a protected species.
575
00:34:38,663 --> 00:34:41,383
Illegal hunting of
crocodiles on Lake Nasser
576
00:34:41,380 --> 00:34:45,210
has increased since the 2011 revolution.
577
00:34:47,591 --> 00:34:49,801
Most of the poachers come from Cairo,
578
00:34:49,797 --> 00:34:51,427
or the gulf countries,
579
00:34:51,434 --> 00:34:52,934
and are willing to pay a premium
580
00:34:52,932 --> 00:34:55,852
to kill several specimens.
581
00:35:22,166 --> 00:35:26,246
Poaching isn't just a
problem for crocodiles.
582
00:35:26,252 --> 00:35:30,592
Some types of birds are
also targeted by hunters.
583
00:35:30,594 --> 00:35:32,174
This is especially true
584
00:35:32,173 --> 00:35:34,723
for birds of prey.
585
00:35:49,194 --> 00:35:50,874
Haytham Ibrahim wants to see
586
00:35:50,865 --> 00:35:52,405
if there are still falcons
587
00:35:52,410 --> 00:35:55,540
in the temple of Wadi es-Sebua.
588
00:35:56,067 --> 00:36:00,037
In the past, he has seen
several of them nesting here.
589
00:36:06,423 --> 00:36:08,503
This small temple beside the lake,
590
00:36:08,501 --> 00:36:12,221
is associated with the falcon god, Horus.
591
00:36:13,180 --> 00:36:14,930
Symbol of the rising sun
592
00:36:14,933 --> 00:36:17,593
and war-like power.
593
00:36:23,431 --> 00:36:26,811
- So birds make lots
of feces on the temple.
594
00:36:26,811 --> 00:36:31,371
This is mainly for
swallows and maybe ospreys.
595
00:36:32,151 --> 00:36:35,831
Sometimes, doves of bigger size.
596
00:36:38,908 --> 00:36:42,288
So between the rocks
and in the little holes
597
00:36:42,286 --> 00:36:45,626
we can see lots of nests.
598
00:36:45,628 --> 00:36:50,508
A good number of ospreys
are breeding inside here.
599
00:36:50,760 --> 00:36:53,800
But I can't see any falcons.
600
00:36:55,474 --> 00:36:58,304
The presence of
so many sparrows and swallows
601
00:36:58,295 --> 00:37:02,635
is a sure sign that no falcons
are nesting here anymore.
602
00:37:07,061 --> 00:37:09,431
- People used to catch falcons
603
00:37:09,428 --> 00:37:11,818
and sell to others who were hunting,
604
00:37:11,821 --> 00:37:15,731
and they train the falcon for hunting.
605
00:37:15,731 --> 00:37:19,201
So this strong and small-sized falcons
606
00:37:19,204 --> 00:37:21,794
really bring good money,
607
00:37:21,792 --> 00:37:24,162
if they catch a juvenile one
608
00:37:24,160 --> 00:37:28,120
and they still have a
chance to be trained.
609
00:37:28,119 --> 00:37:28,999
But on the other hand,
610
00:37:29,002 --> 00:37:30,592
if you catch a kestrel which is not good
611
00:37:30,591 --> 00:37:32,761
for hunting or training,
612
00:37:32,762 --> 00:37:37,292
they kill it, stuff, and
then sell as a decoration.
613
00:37:37,291 --> 00:37:39,811
So this really effects the number,
614
00:37:39,811 --> 00:37:42,261
the total population of this species
615
00:37:42,260 --> 00:37:44,520
around the area here.
616
00:37:54,021 --> 00:37:56,951
Once his inspection
of the lake is complete,
617
00:37:56,947 --> 00:37:59,487
Haytham remarks that there
are a lot fewer birds
618
00:37:59,490 --> 00:38:02,780
than in previous years.
619
00:38:03,785 --> 00:38:06,165
- We try to understand why.
620
00:38:06,165 --> 00:38:09,165
Maybe, because we have
a really cold winter
621
00:38:09,172 --> 00:38:12,132
than the last five years.
622
00:38:12,133 --> 00:38:15,843
Also the hunting is still
going in Lake Nasser,
623
00:38:15,837 --> 00:38:19,927
which really affecting lots of species.
624
00:38:30,976 --> 00:38:31,726
Each year,
625
00:38:31,731 --> 00:38:33,111
the water levels of Lake Nasser
626
00:38:33,112 --> 00:38:37,662
rises several meters during flood season.
627
00:38:39,161 --> 00:38:40,711
This seasonal phenomenon,
628
00:38:40,705 --> 00:38:43,815
originates each summer in Ethiopia.
629
00:38:47,334 --> 00:38:50,594
Heavy rains swell the Nile
into a gushing torrent,
630
00:38:50,585 --> 00:38:54,245
that sweeps away the
black soil in Ethiopia.
631
00:38:59,037 --> 00:39:00,767
The current used to distribute silt
632
00:39:00,767 --> 00:39:02,217
along the Nile valley,
633
00:39:02,218 --> 00:39:05,598
all the way to the Mediterranean Sea.
634
00:39:08,348 --> 00:39:09,968
This silt is what enabled Egypt
635
00:39:09,973 --> 00:39:13,193
to become a great agricultural
civilization in antiquity.
636
00:39:15,440 --> 00:39:17,610
Because the Nile carried this fertile soil
637
00:39:17,611 --> 00:39:20,191
to the heart of the desert.
638
00:39:21,326 --> 00:39:23,106
But today, the Nile has been stopped
639
00:39:23,114 --> 00:39:24,874
cold in its tracks,
640
00:39:24,867 --> 00:39:26,947
and dumps most of it's precious sediments
641
00:39:26,946 --> 00:39:29,656
into Lake Nasser.
642
00:39:34,457 --> 00:39:36,257
Egypt has tamed the Nile
643
00:39:36,256 --> 00:39:39,866
and put an end to this natural cycle.
644
00:39:39,874 --> 00:39:43,394
But what is the actual
impact of this progress?
645
00:39:45,545 --> 00:39:48,465
- The sediment is a long story.
646
00:39:48,470 --> 00:39:52,100
We have many effects in
Egypt from these sediments.
647
00:39:52,099 --> 00:39:54,649
Only 3% of the sediment
648
00:39:54,654 --> 00:39:57,204
can pass through the high damn,
649
00:39:57,196 --> 00:39:59,236
and considering that the lake
650
00:39:59,240 --> 00:40:03,620
receives one hundred million
tons of sediment yearly,
651
00:40:03,616 --> 00:40:07,486
you can imagine what this sediment can do.
652
00:40:11,790 --> 00:40:14,000
Samples
and scientific analyses
653
00:40:13,996 --> 00:40:16,376
have shown that over the past 40 years,
654
00:40:16,376 --> 00:40:18,176
an incredible amount of alluvium
655
00:40:18,175 --> 00:40:20,795
has been deposited in Lake Nasser.
656
00:40:20,799 --> 00:40:24,349
Over 96 million cubic meters per year.
657
00:40:30,888 --> 00:40:32,608
The sediment is deposited mainly
658
00:40:32,607 --> 00:40:34,817
in the middle of the lake.
659
00:40:46,829 --> 00:40:49,309
- In the southern part of Lake Nasser,
660
00:40:49,313 --> 00:40:51,453
the sediment has raised the level
661
00:40:51,450 --> 00:40:52,530
of the riverbed,
662
00:40:52,529 --> 00:40:55,669
but 50 meters.
663
00:40:57,626 --> 00:40:58,866
Little by little,
664
00:40:58,868 --> 00:41:00,708
Lake Nasser is being smothered,
665
00:41:00,714 --> 00:41:04,264
asphyxiated by the
alluvium deposited in it.
666
00:41:04,964 --> 00:41:07,884
All lakes gradually fill this way,
667
00:41:07,878 --> 00:41:09,558
but the phenomenon is particularly
668
00:41:09,561 --> 00:41:11,561
pronounced in reservoirs,
669
00:41:11,558 --> 00:41:14,318
and especially in Lake Nasser.
670
00:41:16,527 --> 00:41:19,277
If sedimentation continues at this pace,
671
00:41:19,279 --> 00:41:20,969
the lake could be completely filled
672
00:41:20,974 --> 00:41:23,484
in less than 300 years.
673
00:41:23,482 --> 00:41:25,732
Much faster than engineers predicted
674
00:41:25,734 --> 00:41:28,454
at the time of its creation.
675
00:41:31,121 --> 00:41:32,541
The sediment is now beginning
676
00:41:32,537 --> 00:41:34,907
to form a new delta in Sudan,
677
00:41:34,906 --> 00:41:37,696
at the mouth of the Nile, in Lake Nubia.
678
00:41:37,704 --> 00:41:39,844
Consequently, there is a serious shortage
679
00:41:39,840 --> 00:41:42,800
of it elsewhere further north.
680
00:41:47,340 --> 00:41:48,800
Bereft of it's silt,
681
00:41:48,803 --> 00:41:52,183
the Egyptian delta is slowly disappearing.
682
00:41:52,762 --> 00:41:55,402
It's natural erosion
is no long compensated
683
00:41:55,397 --> 00:41:58,227
by the regular arrival of fresh soil,
684
00:41:58,230 --> 00:41:59,520
endangering the countries
685
00:41:59,519 --> 00:42:02,389
largest agricultural zone.
686
00:42:05,649 --> 00:42:07,819
To make up for the absence of silt,
687
00:42:07,820 --> 00:42:12,040
Egyptian farmers use a lot
of chemical fertilizers.
688
00:42:12,035 --> 00:42:14,235
This practice further pollutes the river
689
00:42:14,240 --> 00:42:17,290
and impoverishes the soil.
690
00:42:18,002 --> 00:42:19,842
Egypt will need to find a solution
691
00:42:19,836 --> 00:42:22,786
to the this problem in the years to come.
692
00:42:28,219 --> 00:42:31,759
- This piece of silt deposit
693
00:42:31,760 --> 00:42:36,310
comes from a village along the Nile.
694
00:42:36,310 --> 00:42:40,690
It's from 1962, the last
flood before the dam.
695
00:42:53,996 --> 00:42:56,066
For Nubians like Shaaban,
696
00:42:56,074 --> 00:42:57,364
who grew up along the Nile,
697
00:42:57,362 --> 00:42:59,212
before the lake was created,
698
00:42:59,209 --> 00:43:02,709
silt was much more than just fertilizer.
699
00:43:03,841 --> 00:43:05,751
- Silt is a fertilizer,
700
00:43:05,745 --> 00:43:10,095
but Nubians also used it as medicine.
701
00:43:10,099 --> 00:43:11,459
We used it to make masks
702
00:43:11,457 --> 00:43:14,007
for protection from the intense heat.
703
00:43:14,012 --> 00:43:15,602
We used it for pregnant women
704
00:43:15,602 --> 00:43:18,052
to treat constipation.
705
00:43:18,051 --> 00:43:21,361
All you had to do was eat a piece of it.
706
00:43:27,491 --> 00:43:29,151
Silt is Egypt.
707
00:43:29,151 --> 00:43:32,111
If there's no silt, Egypt doesn't exist,
708
00:43:32,112 --> 00:43:33,702
because Egypt has always been
709
00:43:33,702 --> 00:43:36,452
an agricultural country.
710
00:43:46,125 --> 00:43:47,955
In Arabic, the word "dam",
711
00:43:47,959 --> 00:43:50,289
"sadd", means to block.
712
00:43:50,291 --> 00:43:53,761
How can something that blocks be positive?
713
00:43:57,479 --> 00:43:59,519
Another huge dam on the Nile
714
00:43:59,523 --> 00:44:03,353
could completely change the
stakes in years to come.
715
00:44:03,818 --> 00:44:05,238
Located in Ethiopia,
716
00:44:05,235 --> 00:44:08,435
2,000 kilometers upstream
from Lake Nasser,
717
00:44:08,439 --> 00:44:10,319
the Renaissance Dam is slated
718
00:44:10,320 --> 00:44:14,100
for completion in 2017.
719
00:44:14,099 --> 00:44:15,559
When it begins operating,
720
00:44:15,564 --> 00:44:19,424
a large artificial lake
with be formed in Ethiopia.
721
00:44:19,416 --> 00:44:20,896
For the decade or so it takes
722
00:44:20,904 --> 00:44:22,704
to fill this new reservoir,
723
00:44:22,702 --> 00:44:26,712
it will have a decisive
impact on Lake Nasser.
724
00:44:27,509 --> 00:44:29,009
On the plus side,
725
00:44:29,006 --> 00:44:32,126
the lake will receive less sediment.
726
00:44:32,129 --> 00:44:33,759
On the down side,
727
00:44:33,755 --> 00:44:34,875
the flooding of the Nile
728
00:44:34,881 --> 00:44:37,541
will bring a lot less water.
729
00:44:37,541 --> 00:44:39,001
The lakes water level is likely
730
00:44:39,003 --> 00:44:40,763
to drop drastically,
731
00:44:40,756 --> 00:44:43,636
to the point of losing
part of it's ecosystem,
732
00:44:43,635 --> 00:44:46,525
the cores, the lace-like
branches of the lake,
733
00:44:46,529 --> 00:44:49,309
where most of the fish breed.
734
00:44:49,309 --> 00:44:53,239
And that's exactly what
worries Dr. El-Shabrawy.
735
00:44:53,953 --> 00:44:57,273
- When the dam in Ethopia is completed,
736
00:44:57,273 --> 00:45:01,073
it will be a disaster for Lake Nasser.
737
00:45:01,070 --> 00:45:04,330
Particularly for the littoral area.
738
00:45:05,949 --> 00:45:10,089
The level of the lake will drop a lot,
739
00:45:10,094 --> 00:45:12,254
maybe more than 20 meters,
740
00:45:12,253 --> 00:45:16,513
and we will lose thousands
of kilometers of littoral.
741
00:45:18,708 --> 00:45:21,018
The tilapia depends on these areas
742
00:45:21,019 --> 00:45:24,359
for breeding and as a nursery ground.
743
00:45:28,275 --> 00:45:29,525
Dr. El-Shabrawy thinks the
744
00:45:29,529 --> 00:45:31,359
fishing industry on the lake is going to
745
00:45:31,363 --> 00:45:34,063
sorely feel the effects.
746
00:45:34,059 --> 00:45:36,239
But he has an idea to counter-balance
747
00:45:36,242 --> 00:45:38,752
this eventuality.
748
00:45:42,999 --> 00:45:44,079
The middle of the lake holds
749
00:45:44,079 --> 00:45:45,659
an extremely high concentration
750
00:45:45,658 --> 00:45:48,028
of zooplankton.
751
00:45:48,028 --> 00:45:51,918
But not many fish species feed on it.
752
00:45:52,543 --> 00:45:54,683
- There is a great deal of plankton here,
753
00:45:54,679 --> 00:45:58,729
which settles as organic
matter in the sediment.
754
00:45:59,555 --> 00:46:02,925
So, we would like to have this consumed.
755
00:46:03,642 --> 00:46:04,842
His idea is to introduce
756
00:46:04,838 --> 00:46:06,678
a new type of fish,
757
00:46:06,684 --> 00:46:08,194
a freshwater sardine,
758
00:46:08,193 --> 00:46:09,903
which feeds specifically on
759
00:46:09,900 --> 00:46:12,320
this type of zooplankton.
760
00:46:13,905 --> 00:46:16,075
- It's a species of sardine
761
00:46:16,076 --> 00:46:19,116
that has been introduced
into other African lakes,
762
00:46:19,118 --> 00:46:21,978
and it increases the
production of these lakes,
763
00:46:21,983 --> 00:46:23,833
and it's providing a catch
764
00:46:23,830 --> 00:46:26,500
for more than 10,000 fishermen.
765
00:46:27,789 --> 00:46:29,749
Nevertheless,
Dr. El-Shabrawy
766
00:46:29,751 --> 00:46:31,751
is aware that this kind of operation
767
00:46:31,748 --> 00:46:33,258
is quite complicated
768
00:46:33,257 --> 00:46:35,957
and carries certain risks.
769
00:46:35,962 --> 00:46:38,382
- To introduce a new species into a lake
770
00:46:38,377 --> 00:46:40,637
is very very dangerous.
771
00:46:40,641 --> 00:46:42,511
We should do all the research concerning
772
00:46:42,510 --> 00:46:44,050
its feeding habits,
773
00:46:44,054 --> 00:46:47,314
and the its affects on the
water quality beforehand,
774
00:46:47,305 --> 00:46:51,015
to see how it interacts
with other species,
775
00:46:51,020 --> 00:46:53,740
to see if it reproduces
in the lake or not.
776
00:46:53,737 --> 00:46:55,097
This is very important.
777
00:46:55,095 --> 00:46:57,765
We need two or three years of study
778
00:46:57,766 --> 00:47:01,536
before we can introduce
it safely into the lake.
779
00:47:02,820 --> 00:47:04,360
Lake Nasser's water
780
00:47:04,364 --> 00:47:08,184
is a strategic issue for Egypt.
781
00:47:08,176 --> 00:47:10,026
And yet, this precious resource
782
00:47:10,031 --> 00:47:12,881
continues to dwindle.
783
00:47:12,875 --> 00:47:14,915
Close to 8% of the lake's water
784
00:47:14,918 --> 00:47:19,008
evaporates each year
before it reaches the dam.
785
00:47:19,005 --> 00:47:21,425
Meanwhile, the country
must use more and more
786
00:47:21,432 --> 00:47:25,342
to meet the needs of its
constantly growing population.
787
00:47:26,261 --> 00:47:28,721
In less than 40 years,
the population of Egypt
788
00:47:28,723 --> 00:47:33,063
has increased from 30 to 90 million.
789
00:47:33,483 --> 00:47:36,903
Most of it's inhabitants are
gathered along the Nile Valley,
790
00:47:36,896 --> 00:47:39,396
the country's only fertile zone.
791
00:47:39,404 --> 00:47:43,584
Which only represents 4%
of the Egyptian territory.
792
00:47:44,199 --> 00:47:47,499
This enormous demographic
and environmental pressure,
793
00:47:47,496 --> 00:47:51,316
has given rise to the new valley project.
794
00:47:51,583 --> 00:47:55,463
This huge undertaking
was inaugurated in 1997,
795
00:47:55,461 --> 00:47:57,841
but former president Mubarak.
796
00:47:57,843 --> 00:47:59,393
It's ambition,
797
00:47:59,388 --> 00:48:01,758
to create a new fertile valley,
798
00:48:01,756 --> 00:48:05,596
by pumping water from Lake Nasser.
799
00:48:10,678 --> 00:48:12,808
Billions have already been invested.
800
00:48:12,814 --> 00:48:16,324
But no one is able to
give an exact figure.
801
00:48:16,773 --> 00:48:19,033
First, a gigantic pumping station,
802
00:48:19,026 --> 00:48:20,686
the second largest in the world,
803
00:48:20,686 --> 00:48:23,616
was built and set beside the lake.
804
00:48:27,373 --> 00:48:30,333
The water is first filtered
into a large basin,
805
00:48:30,334 --> 00:48:31,824
then pumped and directed to
806
00:48:31,819 --> 00:48:35,509
and open-air canal heading
straight into the desert.
807
00:48:48,225 --> 00:48:49,765
After 70 kilometers,
808
00:48:49,769 --> 00:48:54,229
the canal divides into three sub-canals.
809
00:48:54,552 --> 00:48:56,852
At it's inception, the new valley project
810
00:48:56,851 --> 00:48:57,981
was meant to bring
811
00:48:57,977 --> 00:49:00,397
hundreds of thousands
of hectares of new land
812
00:49:00,404 --> 00:49:02,034
forth from the sand.
813
00:49:02,029 --> 00:49:05,899
And relocate six million Egyptians.
814
00:49:06,394 --> 00:49:07,614
But for the moment,
815
00:49:07,613 --> 00:49:10,453
this vast project is on hold.
816
00:49:10,452 --> 00:49:14,792
Only a few pilot farms are
using water from the canal.
817
00:49:23,757 --> 00:49:27,717
They grow dates, mangoes,
alfalfa, and grapes,
818
00:49:27,716 --> 00:49:30,796
right in the middle of the desert.
819
00:49:30,804 --> 00:49:33,984
The even attempt to raise sheep.
820
00:49:39,941 --> 00:49:41,321
But for the time being,
821
00:49:41,323 --> 00:49:44,913
these farms are making
no profit whatsoever.
822
00:49:46,861 --> 00:49:48,161
The project is turning out to be
823
00:49:48,161 --> 00:49:49,861
much more difficult to fund
824
00:49:49,856 --> 00:49:51,666
and make happen in the field
825
00:49:51,667 --> 00:49:54,527
that it's developers had foreseen.
826
00:49:55,208 --> 00:49:58,538
Temperatures can drop from
50 - 0 degrees Celsius
827
00:49:58,540 --> 00:50:01,330
between noon and midnight.
828
00:50:01,329 --> 00:50:03,009
Farmland must be watered constantly
829
00:50:03,010 --> 00:50:04,550
to prevent the salt in the soil
830
00:50:04,554 --> 00:50:07,354
from rising to the surface.
831
00:50:11,218 --> 00:50:13,918
The extreme dryness of
the desert and dust storms
832
00:50:13,923 --> 00:50:17,153
complicate things even more.
833
00:50:21,145 --> 00:50:24,195
If the level of Lake Nasser
drops in years to come,
834
00:50:24,198 --> 00:50:26,488
due to the Ethiopian dam,
835
00:50:26,485 --> 00:50:30,525
the new valley project will
be jeopardized even further.
836
00:50:35,831 --> 00:50:38,631
50 years ago, Lake Nasser was the solution
837
00:50:38,629 --> 00:50:41,919
to Egypt's problems, Today,
838
00:50:41,915 --> 00:50:44,045
it is at the heart of the huge challenges
839
00:50:44,051 --> 00:50:46,261
the country faces.
840
00:50:46,255 --> 00:50:49,595
Will Egyptians manage
to preserve this lake,
841
00:50:49,599 --> 00:50:53,939
which provides the water,
electricity, and fish they need?
842
00:50:54,812 --> 00:50:56,592
- What we see today in Lake Nasser,
843
00:50:56,588 --> 00:50:58,188
might not see tomorrow.
844
00:50:58,191 --> 00:50:59,191
There's all of these changes
845
00:50:59,189 --> 00:51:00,649
which are going on for several miles
846
00:51:00,652 --> 00:51:03,112
in other countries.
847
00:51:03,519 --> 00:51:07,009
Lake Nasser is one of the biggest lakes
848
00:51:07,014 --> 00:51:08,914
made by man.
849
00:51:08,907 --> 00:51:10,657
So, it's really got to be here,
850
00:51:10,660 --> 00:51:15,580
witness to the changes which
happened around the lake
851
00:51:15,582 --> 00:51:18,832
and it's a unique example to study
852
00:51:18,833 --> 00:51:22,053
the man/nature reactions.
853
00:51:22,049 --> 00:51:25,829
We should really work
hard to protect this place
854
00:51:25,834 --> 00:51:28,884
before we lost it.
