The most massive

Najmasivnija
00:20
tsunami perfect storm
2
20317
4935
savršena oluja cunami
00:25
is bearing down upon us.
3
25252
3879
se svaljuje na nas.
00:29
This perfect storm
4
29131
3246
Savršena oluja
00:32
is mounting a grim reality, increasingly grim reality,
5
32377
5168
montira sve crniju stvarnost
00:37
and we are facing that reality
6
37545
4950
i mi se s njom suočavamo
00:42
with the full belief
7
42495
1381
potpuno uvjereni
00:43
that we can solve our problems with technology,
8
43876
2556
da probleme možemo riješiti tehnologijom
00:46
and that's very understandable.
9
46432
2296
i to je razumljivo.
00:48
Now, this perfect storm that we are facing
10
48728
4207
Ova savršena oluja s kojom se suočavamo
00:52
is the result of our rising population,
11
52935
3510
je rezultat rasta populacije,
00:56
rising towards 10 billion people,
12
56445
2804
koji se kreće ka deset milijardi ljudi,
00:59
land that is turning to desert,
13
59249
2644
zemljišta koje se pretvara u pustinju
01:01
and, of course, climate change.
14
61893
3108
i klimatskih promjena, naravno.
01:05
Now there's no question about it at all:
15
65001
2661
Uopće nije upitno sljedeće:
01:07
we will only solve the problem
16
67662
1811
riješit ćemo problem samo
01:09
of replacing fossil fuels with technology.
17
69473
3512
zamjenom fosilnih goriva tehnologijom.
01:12
But fossil fuels, carbon -- coal and gas --
18
72985
3128
Ali fosilna goriva, ugljik - ugalj i plin -
01:16
are by no means the only thing
19
76113
2121
sigurno nisu jedino
01:18
that is causing climate change.
20
78234
4118
što uzrokuje klimatske promjene.
01:22
Desertification
21
82352
1883
Dezertifikacija
01:24
is a fancy word for land that is turning to desert,
22
84235
5326
je kitnjasta riječ za zemljište pretvoreno u pustinju
01:29
and this happens only when
23
89561
2301
i to se dešava samo kada
01:31
we create too much bare ground.
24
91862
2009
stvorimo previse golog tla.
01:33
There's no other cause.
25
93871
2006
Drugog uzroka nema.
01:35
And I intend to focus
26
95877
2018
Planiram se usredotočiti
01:37
on most of the world's land that is turning to desert.
27
97895
4906
na većinu svjetskog zemljišta koje se pretvara u pustinju.
01:42
But I have for you a very simple message
28
102801
5293
Ali za vas imam veoma jednostavnu poruku
01:48
that offers more hope than you can imagine.
29
108094
4196
koja nudi više nade nego što možete zamisliti.
01:52
We have environments
30
112290
2068
Imamo okruženja
01:54
where humidity is guaranteed throughout the year.
31
114358
3244
gdje je vlaga zajamčena kroz cijelu godinu.
01:57
On those, it is almost impossible
32
117602
2504
Na njima je gotovo nemoguće
02:00
to create vast areas of bare ground.
33
120106
2789
stvoriti ogromna područja golog tla.
02:02
No matter what you do, nature covers it up so quickly.
34
122895
3622
Šta god uradili, priroda to brzo pokrije.
02:06
And we have environments
35
126517
1747
Imamo okruženja
02:08
where we have months of humidity
36
128264
2693
gdje vlažne mjesece
02:10
followed by months of dryness,
37
130957
1778
prate mjeseci suše
02:12
and that is where desertification is occurring.
38
132735
3478
i tu se dezertifikacija dešava.
02:16
Fortunately, with space technology now,
39
136213
2056
Srećom, uz pomoć svemirske tehnologije,
02:18
we can look at it from space,
40
138269
1677
to možemo promatrati iz svemira
02:19
and when we do, you can see the proportions fairly well.
41
139946
4264
i kada to činimo, jako dobro vidimo proporcije.
02:24
Generally, what you see in green
42
144210
1623
Uglavnom, ono što vidite zeleno
02:25
is not desertifying,
43
145833
1855
ne postaje pustinja
02:27
and what you see in brown is,
44
147688
2306
dok smeđi dijelovi postaju,
02:29
and these are by far the greatest areas of the Earth.
45
149994
4372
a to su daleko najveća područja na Zemlji.
02:34
About two thirds, I would guess, of the world is desertifying.
46
154366
4785
Mislim da oko dvije trećine svijeta postaje pustinja.
02:39
I took this picture in the Tihamah Desert
47
159151
2924
Napravio sam ovu fotografiju u pustinji Tihamah
02:42
while 25 millimeters -- that's an inch of rain -- was falling.
48
162075
3704
dok je 25 milimetara kiše padalo - - to je palac kiše.
02:45
Think of it in terms of drums of water,
49
165779
2712
Smatrajte to buradima vode
02:48
each containing 200 liters.
50
168491
2672
od kojih svaki sadrži 200 litara.
02:51
Over 1,000 drums of water fell on every hectare
51
171163
4600
Preko 1000 buradi vode padne na svaki hektar
02:55
of that land that day.
52
175763
2874
tog zemljišta svaki dan.
02:58
The next day, the land looked like this.
53
178637
2384
Sljedećeg je dana zemlja izgledala ovako.
03:01
Where had that water gone?
54
181021
2823
Gdje je voda otišla?
03:03
Some of it ran off as flooding,
55
183844
2397
Nešto je oteklo u obliku poplave
03:06
but most of the water that soaked into the soil
56
186241
2947
ali većina vode koju je zemlja upila
03:09
simply evaporated out again,
57
189188
2281
je ponovo isparila,
03:11
exactly as it does in your garden
58
191469
2369
kao što to čini u bašti
03:13
if you leave the soil uncovered.
59
193838
3015
ako tlo ostavite otkriveno.
03:16
Now, because the fate of water and carbon
60
196853
3466
Zbog sudbinske povezanosti vode i ugljika
03:20
are tied to soil organic matter,
61
200319
3558
s organskom materijom tla,
03:23
when we damage soils, you give off carbon.
62
203877
3927
kada štetimo tlu, ispuštamo ugljik.
03:27
Carbon goes back to the atmosphere.
63
207804
2826
Ugljik se vraća u atmosferu.
03:30
Now you're told over and over, repeatedly,
64
210630
4105
Rečeno vam je više puta
03:34
that desertification is only occurring
65
214735
3000
da se dezertifikacija dešava samo
03:37
in arid and semi-arid areas of the world,
66
217735
3649
u sušnim i polusušnim dijelovima svijeta,
03:41
and that tall grasslands like this one
67
221384
3975
te da su pašnjaci poput ovog
03:45
in high rainfall are of no consequence.
68
225359
3632
u području bogatom oborinama bez posljedica.
03:48
But if you do not look at grasslands but look down into them,
69
228991
4577
Ako ne promatrate pašnjake nego zavirite u njih,
03:53
you find that most of the soil in that grassland
70
233568
2711
vidjet ćete da je većina tla na pašnjaku
03:56
that you've just seen is bare and covered with a crust of algae,
71
236279
4291
koji ste upravo vidjeli, prekrivena korom algi,
04:00
leading to increased runoff and evaporation.
72
240570
3118
koje dovode do otjecanja i isparavanja.
04:03
That is the cancer of desertification
73
243688
3986
Ovo je rak dezertifikacije
04:07
that we do not recognize till its terminal form.
74
247674
4536
koji ne prepoznajemo dok nije u finalnom obliku.
04:12
Now we know that desertification is caused by livestock,
75
252210
5312
Sada znamo da dezertifikaciju uzrokuje stoka,
04:17
mostly cattle, sheep and goats,
76
257522
2784
većinom goveda, ovce i koze,
04:20
overgrazing the plants,
77
260306
2817
koji pojedu biljke
04:23
leaving the soil bare and giving off methane.
78
263123
4119
i ostave golo tlo koje ispušta metan.
04:27
Almost everybody knows this,
79
267242
2240
Skoro svi ovo znaju,
04:29
from nobel laureates to golf caddies,
80
269482
2835
od nobelovaca do početnika,
04:32
or was taught it, as I was.
81
272317
2631
ako ne znaju, nauče kao ja.
04:34
Now, the environments like you see here,
82
274948
3470
Okruženje kakvo vidite ovdje,
04:38
dusty environments in Africa where I grew up,
83
278418
2864
prašnjavo okruženje u Africi gdje sam odrastao
04:41
and I loved wildlife,
84
281282
2920
i volio divlje životinje,
04:44
and so I grew up hating livestock
85
284202
3392
te sam odrastao mrzeći stoku
04:47
because of the damage they were doing.
86
287594
2028
zbog štete koju je uzrokovala.
04:49
And then my university education as an ecologist
87
289622
3284
Moje univerzitetsko školovanje kao ekologa
04:52
reinforced my beliefs.
88
292906
3088
ojačalo je moja uvjerenja.
04:55
Well, I have news for you.
89
295994
5276
Pa, imam novosti za vas.
05:01
We were once just as certain
90
301270
3284
Nekoć smo bili uvjereni
05:04
that the world was flat.
91
304554
2280
da je Zemlja ravna.
05:06
We were wrong then, and we are wrong again.
92
306834
3945
Bili smo u krivu i opet smo u krivu.
05:10
And I want to invite you now
93
310779
2175
Sada vas pozivam
05:12
to come along on my journey of reeducation and discovery.
94
312954
6254
da krenete na moje putovanje reedukacije i otkrića.
05:19
When I was a young man,
95
319208
2571
Dok sam bio mladić,
05:21
a young biologist in Africa,
96
321779
2895
mladi biolog u Africi,
05:24
I was involved in setting aside marvelous areas
97
324674
4417
bio sam uključen u izdvajanje čudesnih područja
05:29
as future national parks.
98
329091
2519
kao budućih nacionalnih parkova.
05:31
Now no sooner — this was in the 1950s —
99
331610
3427
Ranije ne, ali pedesetih,
05:35
and no sooner did we remove the hunting,
100
335037
3168
prije nego smo ukinuli lov,
05:38
drum-beating people to protect the animals,
101
338205
3481
motivisali smo ljude da štite životinje,
05:41
than the land began to deteriorate,
102
341686
1893
onda je zemlja poćela da se raspada,
05:43
as you see in this park that we formed.
103
343579
4246
kao što vidite u parku koji smo formirali.
05:47
Now, no livestock were involved,
104
347825
2323
Stoka nije bila uključena
05:50
but suspecting that we had too many elephants now,
105
350148
3632
ali sumnjali smo da je slonova previše.
05:53
I did the research and I proved we had too many,
106
353780
4265
Nakon što je istraživanje pokazalo da ih ima previše,
05:58
and I recommended that we would have to reduce their numbers
107
358045
3584
preporučio sam smanjenje broja slonova
06:01
and bring them down to a level that the land could sustain.
108
361629
4052
na razinu koju zemljište može izdržati.
06:05
Now, that was a terrible decision for me to have to make,
109
365681
3784
To je bila grozna odluka za donijeti
06:09
and it was political dynamite, frankly.
110
369465
2859
i iskreno, bila je politički dinamit.
06:12
So our government formed a team of experts
111
372324
3125
Tako je naša vlada formirala tim stručnjaka
06:15
to evaluate my research.
112
375449
2641
da procijene moje istraživanje.
06:18
They did. They agreed with me,
113
378090
2407
Procijenili su. Složili su se sa mnom
06:20
and over the following years,
114
380497
1911
i u narednim godinama
06:22
we shot 40,000 elephants to try to stop the damage.
115
382408
5891
smo ubili 40 hiljada slonova pokušavajući zaustaviti štetu.
06:28
And it got worse, not better.
116
388299
3740
Stanje se pogoršalo, a ne popravilo.
06:32
Loving elephants as I do,
117
392039
2499
Obzirom da toliko volim slonove,
06:34
that was the saddest and greatest blunder of my life,
118
394538
3606
ovo je bila najtužnija i najveća greška mog zivota
06:38
and I will carry that to my grave.
119
398144
2728
i to ću odnijeti u grob sa sobom.
06:40
One good thing did come out of it.
120
400872
2472
Iz tog je proizišla jedna dobra stvar.
06:43
It made me absolutely determined
121
403344
3376
To me učinilo apsolutno odlučnim
06:46
to devote my life to finding solutions.
122
406720
5480
da ću posvetiti život pronalasku rješenja.
06:52
When I came to the United States, I got a shock,
123
412200
4085
Kada sam stigao u Sjedinjene Države, šokiralo me
06:56
to find national parks like this one
124
416285
2468
sto su nacionalni parkovi poput ovog
06:58
desertifying as badly as anything in Africa.
125
418753
4231
ubrzano postajali pustinje kao i oni u Africi.
07:02
And there'd been no livestock on this land
126
422984
2004
Stoke na ovoj zemlji nije bilo
07:04
for over 70 years.
127
424988
2724
skoro sedamdeset godina.
07:07
And I found that American scientists
128
427712
1926
Otkrio sam da američki znanstvenici
07:09
had no explanation for this
129
429638
2914
nemaju objašnjenje za to
07:12
except that it is arid and natural.
130
432552
2960
osim da se radi o prirodnom isušivanju.
07:15
So I then began looking
131
435512
3360
Onda sam počeo tražiti
07:18
at all the research plots I could
132
438872
3251
sva istraživana zemljišta koja sam mogao
07:22
over the whole of the Western United States
133
442123
2703
diljem zapadnog dijela Sjedinjenih Država,
07:24
where cattle had been removed
134
444826
2201
gdje je stoka uklonjena
07:27
to prove that it would stop desertification,
135
447027
2872
kako bi dokazali da to zaustavlja dezerifikaciju,
07:29
but I found the opposite,
136
449899
1833
ali otkrio sam suprotno,
07:31
as we see on this research station,
137
451732
2822
kao što vidimo pri ovoj istraživackoj stanici,
07:34
where this grassland that was green in 1961,
138
454554
3724
gdje je pašnjak bio zelen 1961.
07:38
by 2002 had changed to that situation.
139
458278
5013
i do 2002. promijenjen u ovu situaciju.
07:43
And the authors of the position paper on climate change
140
463291
4719
Autori stajališta o klimatskim promjenama
07:48
from which I obtained these pictures
141
468010
2553
od kojih sam dobio ove fotografije
07:50
attribute this change to "unknown processes."
142
470563
5819
pripisuju ovu promjenu "nepoznatim procesima".
07:56
Clearly, we have never understood
143
476382
3994
Očito nikad nismo shvatili
08:00
what is causing desertification,
144
480376
2684
šta uzrokuje dezertifikaciju
08:03
which has destroyed many civilizations
145
483060
3048
koja je uništila mnoge civilizacije
08:06
and now threatens us globally.
146
486108
2692
i sada nam prijeti na globalnoj razini.
08:08
We have never understood it.
147
488800
2453
Nikad to nismo shvatili.
08:11
Take one square meter of soil
148
491253
2119
Jedan kvadratni metar zemljišta
08:13
and make it bare like this is down here,
149
493372
2703
ogoljen kao ovaj ovdje,
08:16
and I promise you, you will find it much colder at dawn
150
496075
3179
bit će mnogo hladniji u zoru
08:19
and much hotter at midday
151
499254
2804
i mnogo topliji u podne,
08:22
than that same piece of ground if it's just covered with litter,
152
502058
3670
nego taj isti dio zemljišta koji je pokriven otpatkom,
08:25
plant litter.
153
505728
1614
biljnim otpatkom.
08:27
You have changed the microclimate.
154
507342
3037
Promijenila se mikroklima.
08:30
Now, by the time you are doing that
155
510379
2099
U isto vrijeme
08:32
and increasing greatly the percentage of bare ground
156
512478
5588
povećava se površina ogoljenog tla
08:38
on more than half the world's land,
157
518066
4025
na više od pola svjetskog zemljišta
08:42
you are changing macroclimate.
158
522091
3230
i mijenja se makroklima.
08:45
But we have just simply not understood
159
525321
2589
Jednostavno nismo razumjeli
08:47
why was it beginning to happen 10,000 years ago?
160
527910
3986
zašto se to počelo dešavati prije 10 hiljada godina?
08:51
Why has it accelerated lately?
161
531896
2650
Zašto se u zadnje vrijeme ubrzava?
08:54
We had no understanding of that.
162
534546
1967
To nismo mogli razumjeti.
08:56
What we had failed to understand
163
536513
3425
Ono što nam je promicalo
08:59
was that these seasonal humidity environments of the world,
164
539938
3823
su ona okruženja u svijetu sa sezonskom vlažnošću
09:03
the soil and the vegetation
165
543761
2896
čije su tlo i vegetacija
09:06
developed with very large numbers of grazing animals,
166
546657
5792
razvijeni uz veliki broj pašnjackih životinja,
09:12
and that these grazing animals
167
552449
2624
a te su pašnjačke životinje
09:15
developed with ferocious pack-hunting predators.
168
555073
5392
razvijene uz žestoke grabežljivce koji love krda.
09:20
Now, the main defense against pack-hunting predators
169
560465
3892
Glavna obrana od grabežljivaca
09:24
is to get into herds,
170
564357
2341
je okupljanje u krda
09:26
and the larger the herd, the safer the individuals.
171
566698
3992
i što je krdo veće, pojedinci su sigurniji.
09:30
Now, large herds dung and urinate all over their own food,
172
570690
4831
Velika krda obavljaju veliku i malu nuždu po vlastitoj hrani
09:35
and they have to keep moving,
173
575521
3000
i moraju se stalno kretati,
09:38
and it was that movement
174
578521
1917
a to je kretanje
09:40
that prevented the overgrazing of plants,
175
580438
2804
spriječilo preveliku ispašu biljaka,
09:43
while the periodic trampling
176
583242
2399
dok je povremeno gaženje
09:45
ensured good cover of the soil,
177
585641
2520
osiguralo dobar pokrov za tlo
09:48
as we see where a herd has passed.
178
588161
3112
kao što vidimo kuda je prošlo stado.
09:51
This picture is a typical seasonal grassland.
179
591273
6228
Na ovoj fotografiji je tipičan sezonski pašnjak.
09:57
It has just come through four months of rain,
180
597501
2792
Nakon četiri mjeseca kiše
10:00
and it's now going into eight months of dry season.
181
600293
3682
počinje osam mjeseci duga suha sezona.
10:03
And watch the change as it goes into this long dry season.
182
603975
3468
Pogledajte prelazak u dugu suhu sezonu.
10:07
Now, all of that grass you see aboveground
183
607443
3076
Sva površinska trava koju vidite
10:10
has to decay biologically
184
610519
3748
prirodno trune
10:14
before the next growing season, and if it doesn't,
185
614267
3524
prije sljedeće sezone rasta, a ako ne istrune,
10:17
the grassland and the soil begin to die.
186
617791
4193
pašnjak i tlo umiru.
10:21
Now, if it does not decay biologically,
187
621984
3195
Ako prirodno ne istrune,
10:25
it shifts to oxidation, which is a very slow process,
188
625179
5139
počinje oksidiacija, koja je veoma spor proces,
10:30
and this smothers and kills grasses,
189
630318
2955
koja guši i ubija travu,
10:33
leading to a shift to woody vegetation
190
633273
3109
vodi promjeni u drvenastu vegetaciju
10:36
and bare soil, releasing carbon.
191
636382
3420
i golo tlo koje ispušta ugljik.
10:39
To prevent that, we have traditionally used fire.
192
639802
5104
Za sprječavanje toga tradicionalno smo koristili vatru.
10:44
But fire also leaves the soil bare, releasing carbon,
193
644906
5849
Ali i vatra ostavlja golo tlo koje onda ispusta ugljik,
10:50
and worse than that,
194
650755
2391
a što je jos gore,
10:53
burning one hectare of grassland
195
653146
2680
paljenje pašnjaka veličine jednog hektra
10:55
gives off more, and more damaging, pollutants
196
655826
3160
zagađuje više i štetnije
10:58
than 6,000 cars.
197
658986
2914
od 6 hiljada automobila.
11:01
And we are burning in Africa, every single year,
198
661900
4393
A svake godine u Africi se pali
11:06
more than one billion hectares of grasslands,
199
666293
4639
više od jedne milijarde hektara pašnjaka
11:10
and almost nobody is talking about it.
200
670932
3626
i gotovo niko o tome ne govori.
11:14
We justify the burning, as scientists,
201
674558
4339
Opravdavamo paljenje, kao naučnici,
11:18
because it does remove the dead material
202
678897
2913
jer uklanja mrtvi materijal
11:21
and it allows the plants to grow.
203
681810
3303
i dozvoljava rast biljkama.
11:25
Now, looking at this grassland of ours that has gone dry,
204
685113
3096
Ako pogledamo naše pašnjake koji se suše,
11:28
what could we do to keep that healthy?
205
688209
2696
šta možemo učiniti da ih održimo zdravima?
11:30
And bear in mind, I'm talking of most of the world's land now.
206
690905
3024
Imajte na umu da govorim o većini svjetskog zemljišta.
11:33
Okay? We cannot reduce animal numbers to rest it more
207
693929
4688
OK? Ne možemo smanjivati broj životinja kako bi odmorili tlo
11:38
without causing desertification and climate change.
208
698617
3616
bez uzrokovanja dezertifikacije i klimatskih promjena.
11:42
We cannot burn it without causing
209
702233
3137
Ne možemo ga spaliti bez uzrokovanja
11:45
desertification and climate change.
210
705370
2265
dezertifikacije i klimatskih promjena.
11:47
What are we going to do?
211
707635
3985
Šta ćemo onda učiniti?
11:53
There is only one option,
212
713680
2390
Imamo samo jednu mogućnost,
11:56
I'll repeat to you, only one option
213
716070
2861
ponavljam, samo je jedna mogućnost ostala
11:58
left to climatologists and scientists,
214
718931
2719
na raspolaganju klimatolozima i naučnicima,
12:01
and that is to do the unthinkable,
215
721650
2928
a to je da naprave nezamislivo
12:04
and to use livestock,
216
724578
2736
i da koriste stoku,
12:07
bunched and moving,
217
727314
2955
koja se kreće u grupi,
12:10
as a proxy for former herds and predators,
218
730269
3389
kao zamjenu za nekadašnja krda i predatore
12:13
and mimic nature.
219
733658
1744
te oponašaju prirodu.
12:15
There is no other alternative left to mankind.
220
735402
4504
Čovječanstvo je ostalo bez alternative.
12:19
So let's do that.
221
739906
2448
Uradimo to onda.
12:22
So on this bit of grassland, we'll do it, but just in the foreground.
222
742354
3370
Uradit ćemo to na ovom dijelu pašnjaka ali samo prednjem dijelu.
12:25
We'll impact it very heavily with cattle to mimic nature,
223
745724
3238
Snažno ćemo utjecati pomoću stoke koja oponaša prirodu.
12:28
and we've done so, and look at that.
224
748962
2824
Učinili smo tako i pogledajte to.
12:31
All of that grass is now covering the soil
225
751786
3360
Sva ta trava sada pokriva tlo
12:35
as dung, urine and litter or mulch,
226
755146
3970
kao izmet, urin, otpad ili nagrnuta zemlja,
12:39
as every one of the gardeners amongst you would understand,
227
759116
3280
kao što je jasno svakom vrtlaru
12:42
and that soil is ready to absorb and hold the rain,
228
762396
4361
i to je tlo spremno da upija i čuva kišu,
12:46
to store carbon, and to break down methane.
229
766757
5007
da skladišti ugljik i razgrađuje metan.
12:51
And we did that,
230
771764
2230
Uradili smo to
12:53
without using fire to damage the soil,
231
773994
2770
bez korištenja vatre koja oštećuje tlo
12:56
and the plants are free to grow.
232
776764
3136
i biljke mogu slobodno rasti.
12:59
When I first realized
233
779900
2264
Kada sam tek shvatio
13:02
that we had no option as scientists
234
782164
2482
da kao naučnici nemamo izbora
13:04
but to use much-vilified livestock
235
784646
2760
nego koristiti pripitomljenu stoku
13:07
to address climate change and desertification,
236
787406
5247
za rješavanje problema klimatskih promjena i širenja pustinje,
13:12
I was faced with a real dilemma.
237
792653
2235
bio sam suočen sa stvarnom dilemom.
13:14
How were we to do it?
238
794888
1725
Kako bi to trebali učiniti?
13:16
We'd had 10,000 years of extremely knowledgeable pastoralists
239
796613
4564
Imali smo izuzetno obrazovane stočare 10 hiljada godina
13:21
bunching and moving their animals,
240
801177
1948
koji su kretali svoje životinje
13:23
but they had created the great manmade deserts of the world.
241
803125
3667
ali su stvorili velike svjetske pustinje.
13:26
Then we'd had 100 years of modern rain science,
242
806792
3879
Onda smo sto godina imali modernu znanost o kiši
13:30
and that had accelerated desertification,
243
810671
3259
i to je ubrzalo dezertifikaciju,
13:33
as we first discovered in Africa
244
813930
2173
što smo otkrili u Africi
13:36
and then confirmed in the United States,
245
816103
2664
i onda potvrdili u Sjedinjenim Državama
13:38
and as you see in this picture
246
818767
2119
kao što možete vidjeti na ovim fotografijama
13:40
of land managed by the federal government.
247
820886
3361
zemljišta kojim je upravljala federalna vlada.
13:44
Clearly more was needed
248
824247
1901
Očito je bilo potrebno više
13:46
than bunching and moving the animals,
249
826148
2089
od okupljanja i kretanja životinja
13:48
and humans, over thousands of years,
250
828237
3570
te ljudi tisućama godina
13:51
had never been able to deal with nature's complexity.
251
831807
4386
nisu bili u stanju da se nose sa složenošću prirode.
13:56
But we biologists and ecologists
252
836193
2384
Mi biolozi i ekolozi
13:58
had never tackled anything as complex as this.
253
838577
2969
nikad nismo rješavali ništa ovako složeno.
14:01
So rather than reinvent the wheel,
254
841546
2639
Dakle, umjesto da otkrivam toplu vodu,
14:04
I began studying other professions to see if anybody had.
255
844185
4136
počeo sam istraživati druga zanimanja da vidim da li je tko.
14:08
And I found there were planning techniques
256
848321
2472
Otkrio sam da postoje tehnike planiranja
14:10
that I could take and adapt to our biological need,
257
850793
3772
koje bih mogao prilagoditi našim biološkim potrebama
14:14
and from those I developed what we call
258
854565
2697
i od onih koje sam razvio i koje zovemo
14:17
holistic management and planned grazing,
259
857262
3310
holističko upravljanje i planiranje ispaše,
14:20
a planning process,
260
860572
1799
proces planiranja
14:22
and that does address all of nature's complexity
261
862371
3695
odnosi se na rješavanje složenosti prirode
14:26
and our social, environmental, economic complexity.
262
866066
5249
i naše društvene, ekološke i ekonomske složenosti.
14:31
Today, we have young women like this one
263
871315
2664
Danas imamo mlade žene poput ove
14:33
teaching villages in Africa
264
873979
2368
koja podučava u selima u Africi
14:36
how to put their animals together into larger herds,
265
876347
2936
kako okupiti životinje u veća stada,
14:39
plan their grazing to mimic nature,
266
879283
2704
isplanirati njihovu ispašu da liči na prirodnu
14:41
and where we have them hold their animals overnight --
267
881987
4041
i gdje životinje drže preko noći
14:46
we run them in a predator-friendly manner,
268
886028
2259
zadržavamo ih bez grabežljivaca
14:48
because we have a lot of lands, and so on --
269
888287
2322
zato što imamo mnogo zemlje i tako dalje -
14:50
and where they do this and hold them overnight
270
890609
2194
gdje ovo čine i zadržavaju je preko noći
14:52
to prepare the crop fields,
271
892803
1805
kako bi pripremili polje za usjeve
14:54
we are getting very great increases in crop yield as well.
272
894608
3984
i dobiju velike prinose usjeva također.
14:58
Let's look at some results.
273
898592
1617
Pogledajmo neke rezultate.
15:00
This is land close to land that we manage in Zimbabwe.
274
900209
4224
Ovo je zemljište blizu onog kojim se bavimo u Zimbabveu.
15:04
It has just come through four months of very good rains
275
904433
3544
Upravo je završio period kiša koji traje četiri mjeseca
15:07
it got that year, and it's going into the long dry season.
276
907977
3510
i počinje duga sezona suše.
15:11
But as you can see, all of that rain, almost of all it,
277
911487
3035
Kao što možete vidjeti, sva kiša, skoro sva kiša
15:14
has evaporated from the soil surface.
278
914522
3107
je isparila iz površine tla.
15:17
Their river is dry despite the rain just having ended,
279
917629
3802
Rijeka je suha iako su kiše tek stale,
15:21
and we have 150,000 people
280
921431
3520
a imamo 150 hiljada ljudi
15:24
on almost permanent food aid.
281
924951
3750
koji gotovo stalno primaju pomoć u hrani.
15:28
Now let's go to our land nearby on the same day,
282
928701
4496
Sada idemo na našu zemlju, na isti dan,
15:33
with the same rainfall, and look at that.
283
933197
2840
uz istu količinu padalina i pogledajte to.
15:36
Our river is flowing and healthy and clean.
284
936037
2705
Naša rijeka teče i zdrava i čista.
15:38
It's fine.
285
938742
2487
U redu je.
15:41
The production of grass, shrubs, trees, wildlife,
286
941229
5318
Rast trave, grmlja, drveća i životinjskog svijeta,
15:46
everything is now more productive,
287
946547
2856
sve je produktivnije
15:49
and we have virtually no fear of dry years.
288
949403
4105
i gotovo nema straha od sušnih godina.
15:53
And we did that by increasing the cattle and goats
289
953508
5495
To smo učinili povećanjem broja koza i stoke
15:59
400 percent,
290
959003
1925
za 400 posto,
16:00
planning the grazing to mimic nature
291
960928
3130
planiranjem ispaše koja liči prirodnoj
16:04
and integrate them with all the elephants, buffalo,
292
964058
2421
i integracijom sa slonovima, bizonima,
16:06
giraffe and other animals that we have.
293
966479
3587
žirafama i drugim životinjama koje imamo.
16:10
But before we began, our land looked like that.
294
970066
5722
Prije nego sto smo počeli, naša je zemlja ovako izgledala.
16:15
This site was bare and eroding for over 30 years
295
975788
5417
Ovo je mjesto golo i erodira zadnjih 30 godina
16:21
regardless of what rain we got.
296
981205
2769
bez obzira na količinu kiše koja padne.
16:23
Okay? Watch the marked tree and see the change
297
983974
3618
OK? Gledajte označeno drvo i uočite promjenu
16:27
as we use livestock to mimic nature.
298
987592
3653
otkako koristimo stoku koja oponaša prirodu.
16:31
This was another site
299
991245
1462
Ovo je druga lokacija
16:32
where it had been bare and eroding,
300
992707
2378
gdje se dešavalo ogoljenje i erozija,
16:35
and at the base of the marked small tree,
301
995085
2704
a u podnožju označenog malog drveta
16:37
we had lost over 30 centimeters of soil. Okay?
302

izgubili smo preko 30 cm tla. OK?
16:42
And again, watch the change
303
1002077
1609
Ponovo, gledajte promjenu
16:43
just using livestock to mimic nature.
304
1003686
2850
izazvanu samo korištenjem stoke.
16:46
And there are fallen trees in there now,
305
1006536
2131
Vidite oboreno drveće
16:48
because the better land is now attracting elephants, etc.
306
1008667
4957
jer bolje zemljište privlači slonove itd.
16:53
This land in Mexico was in terrible condition,
307
1013624
3656
Ovo zemljište u Meksiku je bilo u strašnom stanju
16:57
and I've had to mark the hill
308
1017280
1954
i morali smo označiti brdo
16:59
because the change is so profound.
309
1019234
4187
jer je promjena tako iznimna.
17:03

I began helping a family in the Karoo Desert in the 1970s
311
1030981
4937
Sedamdesetih sam počeo pomagati porodici u pustini Karoo
17:15
turn the desert that you see on the right there
312
1035918
2968
da pretvore pustinju koju vidite desno
17:18
back to grassland,
313
1038886
1934
nazad u pašnjak
17:20
and thankfully, now their grandchildren are on the land
314
1040820
3522
i srećom, njihovi su unuci na zemlji
17:24
with hope for the future.
315
1044342
1843
s nadom za budućnost.
17:26
And look at the amazing change in this one,
316
1046185
2797
Pogledajte ovu nevjerovatnu promjenu,
17:28
where that gully has completely healed
317
1048982
2712
gdje je jaruga potpuno zacjelila
17:31
using nothing but livestock mimicking nature,
318
1051694
4579
samo uz pomoć stoke koja oponaša prirodu.
17:36
and once more, we have the third generation of that family
319
1056273
4225
Još jednom, imamo treću generaciju te porodice
17:40
on that land with their flag still flying.
320
1060498
3280
na zemlji gdje se još uvijek vijori njihova zastava.
17:43
The vast grasslands of Patagonia
321
1063778
2568
Golemi pašnjaci Patagonije
17:46
are turning to desert as you see here.
322
1066346
2076
se pretvaraju u pustinje, kao što vidite.
17:48
The man in the middle is an Argentinian researcher,
323
1068422
3060
Čovjek u sredini je argentinski istraživač
17:51
and he has documented the steady decline of that land
324
1071482
3644
koji je dokumentovao stalno propadanje tog tla
17:55
over the years as they kept reducing sheep numbers.
325
1075126
3476
tijekom godina dok su konstantno reducirali broj ovaca.
17:58
They put 25,000 sheep in one flock,
326
1078602
4848
Stavili su 25 hiljada ovaca u jedno stado,
18:03
really mimicking nature now with planned grazing,
327
1083450
3949
uistinu oponašajući prirodu s planiranjem ispaše
18:07
and they have documented a 50-percent increase
328
1087399
4343
i zabilježili su povećanje od 50 posto
18:11
in the production of the land in the first year.
329
1091742
3468
u proizvodnji tijekom prve godine.
18:15
We now have in the violent Horn of Africa
330
1095210
3040
Nasilni stočari afričkog roga
18:18
pastoralists planning their grazing to mimic nature
331
1098250
3456
planiraju svoje ispaše oponašajući prirodu
18:21
and openly saying it is the only hope they have
332
1101706
3496
i otvoreno kažu da je to jedina nada koju imaju
18:25
of saving their families and saving their culture.
333
1105202
3168
da spase svoje porodice i očuvaju svoju kulturu.
18:28
Ninety-five percent of that land
334
1108370
2076
95 posto zemlje
18:30
can only feed people from animals.
335
1110446
3660
se prehranjuje od životinja.
18:34
I remind you that I am talking about
336
1114106
2111
Podsjećam vas da govorim
18:36
most of the world's land here that controls our fate,
337
1116217
4441
o većini svjetskog zemljišta koje kontroliše nasu sudbinu,
18:40
including the most violent region of the world,
338
1120658
3056
uključujući najnasilnije dijelove svijeta,
18:43
where only animals can feed people
339
1123714
2952
gdje samo životinje mogu hraniti ljude
18:46
from about 95 percent of the land.
340
1126666
3304
od oko 95 posto zemlje.
18:49
What we are doing globally is causing climate change
341
1129970
5134
Ono sto činimo uzrokuje klimatske promjene
18:55
as much as, I believe, fossil fuels,
342
1135104
3296
jednako kao i fosilna goriva,
18:58
and maybe more than fossil fuels.
343
1138400
3536
ako ne i više od fosilnih goriva.
19:01
But worse than that, it is causing hunger, poverty,
344
1141936
3675
Gore od toga, uzrokuje glad, siromaštvo,
19:05
violence, social breakdown and war,
345
1145611
2997
nasilje, društvene kolapse i rat.
19:08
and as I am talking to you,
346
1148608
2408
Dok vam ovo govorim,
19:11
millions of men, women and children
347
1151016
3150
milioni muškaraca, žena i djece
19:14
are suffering and dying.
348
1154166
2402
pate i umiru.
19:16
And if this continues,
349
1156568
2712
Ako se ovo nastavi,
19:19
we are unlikely to be able to stop the climate changing,
350
1159280
3794
nećemo moći zaustaviti klimatske promjene
19:23
even after we have eliminated the use of fossil fuels.
351
1163074
5047
čak i kada eliminiramo korištenje fosilnih goriva.
19:28
I believe I've shown you how we can work with nature
352
1168121
4236
Vjrujem da sam vam pokazao kako možemo surađivati s prirodom
19:32
at very low cost
353
1172357
2456
uz veoma mali trošak
19:34
to reverse all this.
354
1174813
2496
kako bi sve ovo preokrenuli.
19:37
We are already doing so
355
1177309
2432
Mi to već radimo
19:39
on about 15 million hectares
356
1179741
3996
na oko 15 miliona hektara
19:43
on five continents,
357
1183737
2632
na 5 kontinenata
19:46
and people who understand
358
1186369
1627
i ljudi koji znaju
19:47
far more about carbon than I do
359
1187996
2290
o ugljiku daleko više od mene
19:50
calculate that, for illustrative purposes,
360
1190286
3058
su izračunali, za ilustrativne svrhe,
19:53
if we do what I am showing you here,
361
1193344
2794
da ako budemo radili ovo što vam pokazujem,
19:56
we can take enough carbon out of the atmosphere
362
1196138
4025
možemo osloboditi dovoljno ugljika iz atmosfere
20:00
and safely store it in the grassland soils
363
1200163
3334
i sigurno ga skladištiti u tlu pašnjaka
20:03
for thousands of years,
364
1203497
1626
tisućama godina
20:05
and if we just do that on about half the world's grasslands
365
1205123
4996
i ako to učinimo na polovini svjetskih pašnjaka
20:10
that I've shown you,
366
1210119
1354
koja sam vam pokazao
20:11
we can take us back to pre-industrial levels,
367
1211473
3700
možemo se vratiti na predindustrijski nivo
20:15
while feeding people.
368
1215173
1641
te nahraniti ljude.
20:16
I can think of almost nothing
369
1216814
2772
Ne mogu se sjetiti ničega
20:19
that offers more hope for our planet,
370
1219586
3525
što nudi više nade za našu planetu,
20:23
for your children,
371
1223111
2248
za našu djecu,
20:25
and their children, and all of humanity.
372
1225359
2656
njihovu djecu i ukupno čovjecanstvo.
20:28
Thank you.

3346
Kris Anderson: Ja imam
20:57
and I'm sure everyone here has,
378
1257847
2097
i siguran sam da svi ovdje imaju
20:59
A) a hundred questions, B) wants to hug you.
379
1259944
3728
a) sto pitanja i b) zelju da te zagrle.
21:03
I'm just going to ask you one quick question.
380
1263672
1759
Postavit ću ti samo jedno brzo pitanje.
21:05
When you first start this and you bring in a flock of animals,
381
1265431
3684
Kada počnete s ovim i dovedete prvo stado životinja
21:09
it's desert. What do they eat? How does that part work?
382
1269115
3376
u pustinju. Šta jedu? Kako taj dio funkcionira?
21:12
How do you start?
383
1272491
991
Kako počinjete?
21:13
Allan Savory: Well, we have done this for a long time,
384
1273482
1639
Allan S.: Ovo radimo dugo vremena
21:15
and the only time we have ever had to provide any feed
385
1275121
3618
i jedino smo morali osigurati hranu
21:18
is during mine reclamation,
386
1278739
1769
tijekom melioracije tla
21:20
where it's 100 percent bare.
387
1280508
2314
u slučaju kada je 100 posto golo.
21:22
But many years ago, we took the worst land in Zimbabwe,
388
1282822
4356
Prije mnogo godina, uzeli smo najgore zemljište u Zimbabveu,
21:27
where I offered a £5 note
389
1287178
3094
gdje sam ponudio pet funti
21:30
in a hundred-mile drive
390
1290272
2019
u vožnji dugoj više od 150 km
21:32
if somebody could find one grass
391
1292291
2120
onome ko pronađe vlat trave
21:34
in a hundred-mile drive,
392
1294411
1990
u vožnji dugoj više od 150 km.
21:36
and on that, we trebled the stocking rate,
393
1296401
2786
Na tom području smo utrostručili stočni fond
21:39
the number of animals, in the first year with no feeding,
394
1299187
3776
u prvoj godini bez hranjenja,
21:42
just by the movement, mimicking nature,
395
1302963
2656
samo kroz kretanje i oponašanje prirode,
21:45
and using a sigmoid curve, that principle.
396
1305619
4775
te korištenje principa sigmoidne krivulje.
21:50
It's a little bit technical to explain here, but just that.
397
1310394
2471
Malo je tehnički da bih objasnio ovdje, ali toliko.
21:52
CA: Well, I would love to -- I mean, this such an interesting and important idea.
398
1312865
3712
KA: Volio bih da objasnite, ovo je tako interesantna i važna ideja.
21:56
The best people on our blog are going to come and talk to you
399
1316577
1992
Naši blogeri dolaze razgovarati s Vama
21:58
and try and -- I want to get more on this
400
1318569
2632
i pokušati izvući što više o ovome
22:01
that we could share along with the talk.AS: Wonderful.
401
1321201
2952
kako bi mogli dalje dijeliti uz ovaj govor. AS: Predivno.
22:04
CA: That is an astonishing talk, truly an astonishing talk,
402
1324153
3536
KA: Ovo je nevjerovatan govor, zaista nevjerovatan govor.
22:07
and I think you heard that we all are cheering you on your way.
403
1327689

Mislim da ste čuli da svi navijamo za vas.
22:10
