Come with me to Agbogbloshie,
0
13650
2660
00:16
a neighborhood in the heart of Accra,
1
16334
2786
00:19
named after a god that lives in the Odaw River.
2
19144
3504
00:23
There's a slum, Old Fadama,
3
23503
2814
00:26
built on land reclaimed from the Korle Lagoon,
4
26341
3775
00:30
just before it opens into the Gulf of Guinea.
5
30140
2704
00:33
There's a scrapyard here where people take apart all kinds of things,
6
33908
4108
00:38
from mobile phones to computers,
7
38040
2330
00:40
automobiles to even entire airplanes.
8
40394
2757
00:43
Agbogbloshie's scrapyard is famous
9
43936
2539
00:46
because it has become a symbol of the downside of technology:
10
46499
4479
00:51
the problem of planned obsolescence.
11
51002
2629
00:54
It's seen as a place where devices from around the world end their life,
12
54203
5139
00:59
where your data comes to die.
13
59366
2801
01:03
These are the images that the media loves to show,
14
63754
2770
01:06
of young men and boys burning wires and cables
15
66548
4822
01:11
to recover copper and aluminum,
16
71394
2721
01:14
using Styrofoam and old tires as fuel,
17
74139
3399
01:17
seriously hurting themselves and the environment.
18
77562
3066
01:21
It's a super-toxic process,
19
81993
2091
01:24
producing pollutants that enter the global ecosystem,
20
84108
3877
01:28
build up in fatty tissue
21
88009
2116
01:30
and threaten the top of the food chain.
22
90149
2446
01:33
But this story is incomplete.
23
93950
2587
01:38
There's a lot we can learn from Agbogbloshie,
24
98943
2859
01:41
where scrap collected from city- and nationwide is brought.
25
101826
4529
01:46
For so many of us,
26
106727
1722
01:48
our devices are black boxes.
27
108473
2221
01:50
We know what they do,
28
110718
1415
01:52
but not how they work or what's inside.
29
112157
2690
01:55
In Agbogbloshie, people make it their business
30
115792
2485
01:58
to know exactly what's inside.
31
118301
2057
02:00
Scrap dealers recover copper, aluminum, steel, glass, plastic
32
120382
5536
02:05
and printed circuit boards.
33
125942
1940
02:07
It's called "urban mining."
34
127906
1922
02:09
It's now more efficient for us to mine materials from our waste.
35
129852
5204
02:16
There is 10 times more gold, silver, platinum, palladium
36
136310
4520
02:20
in one ton of our electronics
37
140854
2356
02:23
than in one ton of ore mined from beneath the surface of the earth.
38
143234
3958
02:29
In Agbogbloshie,
39
149600
1571
02:31
weight is a form of currency.
40
151195
2080
02:33
Devices are dissected to recover materials, parts and components
41
153918
5006
02:38
with incredible attention to detail,
42
158948
1816
02:40
down to the aluminum tips of electric plugs.
43
160788
3128
02:45
But scrap dealers don't destroy components that are still functional.
44
165759
4125
02:49
They supply them to repair workshops like this one in Agbogbloshie
45
169908
4018
02:53
and the tens of thousands of technicians across the country
46
173950
4493
02:58
that refurbish electrical and electronic equipment,
47
178467
4091
03:02
and sell them as used products to consumers that may not be able to buy
48
182582
3788
03:06
a new television or a new computer.
49
186394
2148
03:10
Make no mistake about it, there are young hackers in Agbogbloshie --
50
190463
3214
03:13
and I mean that in the very best sense of that word --
51
193701
2844
03:17
that know not only how to take apart computers
52
197315
2696
03:20
but how to put them back together, how to give them new life.
53
200035
3251
03:23
Agbogbloshie reminds us that making is a cycle.
54
203817
3779
03:27
It extends to remaking and unmaking
55
207620
3252
03:30
in order to recover the materials that enable us to make something anew.
56
210896
3933
03:35
We can learn from Agbogbloshie,
57
215472
1928
03:37
where cobblers remake work boots,
58
217424
3851
03:41
where women collect plastic from all over the city,
59
221299
3340
03:44
sort it by type,
60
224663
1498
03:46
shred it, wash it
61
226185
1949
03:48
and ultimately sell it back as feedstock to factories
62
228158
3090
03:51
to make new clothing,
63
231272
1368
03:52
new plastic buckets
64
232664
1767
03:54
and chairs.
65
234455
1161
03:56
Steel is stockpiled separately,
66
236444
2433
03:58
where the carcasses of cars and microwaves and washing machines
67
238901
3930
04:02
become iron rods for new construction;
68
242855
2294
04:05
where roofing sheets become cookstoves;
69
245173
2551
04:07
where shafts from cars become chisels
70
247748
3551
04:11
that are used to scrap more objects;
71
251323
3507
04:14
where aluminum recovered from the radiators of fridges
72
254854
4273
04:19
and air conditioners
73
259151
2723
04:21
are melted down
74
261898
1336
04:23
and use sand casting to make ornaments for the building industry,
75
263258
4054
04:27
for pots which are sold just down the street in the Agbogbloshie market
76
267336
3931
04:31
with a full array of locally made ovens, stoves and smokers,
77
271291
6336
04:37
which are used every day
78
277651
1538
04:39
to make the majority of palm nut soups,
79
279213
3406
04:42
of tea and sugar breads,
80
282643
1877
04:44
of grilled tilapia in the city.
81
284544
1951
04:47
They're made in roadside workshops like this one by welders like Mohammed,
82
287322
4827
04:52
who recover materials from the waste stream
83
292173
2519
04:54
and use them to make all kinds of things,
84
294716
2008
04:56
like dumbbells for working out out of old car parts.
85
296748
2960
04:59
But here's what's really cool:
86
299732
1492
05:01
the welding machines they use look like this,
87
301248
2339
05:03
and they're made by specially coiling copper
88
303611
4235
05:07
around electrical steel recovered from old transformer scrap.
89
307870
6054
05:14
There's an entire industry just next to Agbogbloshie
90
314630
3420
05:18
making locally fabricated welding machines that power local fabrication.
91
318074
4579
05:23
What's really cool as well is that there's a transfer of skills and knowledge
92
323549
3809
05:27
across generations,
93
327382
1430
05:28
from masters to apprentices,
94
328836
1974
05:30
but it's done through active learning, through heuristic learning,
95
330834
3719
05:34
learning by doing and by making.
96
334577
1947
05:36
And this stands in sharp contrast
97
336548
2217
05:38
to the experience of many students in school,
98
338789
2409
05:41
where lecturers lecture,
99
341222
1609
05:42
and students write things down and memorize them.
100
342855
2705
05:46
It's boring, but the real problem is
101
346099
2875
05:48
this somehow preempts their latent or their inherent entrepreneurial power.
102
348998
6114
05:55
They know books but not how to make stuff.
103
355525
2260
05:58
Four years ago, my cofounder Yasmine Abbas and I asked:
104
358872
4094
06:02
What would happen if we could couple
105
362990
2359
06:05
the practical know-how of makers in the informal sector
106
365373
3636
06:09
with the technical knowledge of students and young professionals
107
369033
4746
06:13
in STEAM fields --
108
373803
1393
06:15
science, technology, engineering, arts and mathematics --
109
375220
3797
06:19
to build a STEAM-powered innovation engine
110
379041
3365
06:22
to drive what we call "Sankofa Innovation," which I'll explain.
111
382430
4057
06:27
We took forays into the scrapyard
112
387656
3757
06:31
to look for what could be repurposed,
113
391437
2844
06:34
like DVD writers that could become laser etchers,
114
394305
2921
06:37
or the power supplies of old servers
115
397250
3662
06:40
for a start-up in Kumasi making 3D printers out of e-waste.
116
400936
3955
06:45
The key was to bring together young people from different backgrounds
117
405453
3734
06:49
that ordinarily never have anything to do with each other,
118
409211
3507
06:52
to have a conversation about how they could collaborate
119
412742
3720
06:56
and to test and develop new machines and tools
120
416486
4109
07:00
that could allow them to shred and strip copper instead of burning it,
121
420619
3911
07:04
to mold plastic bricks and tiles,
122
424554
3154
07:07
to build new computers out of components recovered from dead electronics,
123
427732
5554
07:13
to build a drone.
124
433310
1848
07:16
And here you can see it flying for the first time in Agbogbloshie.
125
436142
4628
07:22
(Applause)
126
442460
3974
07:27
Yasmine and I have collaborated with over 1,500 young people,
127
447129
4177
07:31
750 from STEAM fields,
128
451330
3351
07:34
and over 750 grassroots makers and scrap dealers
129
454705
4553
07:39
from Agbogbloshie and beyond.
130
459282
2045
07:41
They've joined hands together to develop a platform
131
461351
4507
07:46
which they call Spacecraft,
132
466665
2956
07:49
a hybrid physical and digital space for crafting,
133
469645
3617
07:53
more of a process than a product,
134
473286
2941
07:56
an open architecture for making,
135
476251
3884
08:00
which involves three parts:
136
480159
1681
08:01
a makerspace kiosk, which is prefab and modular;
137
481864
3004
08:04
tool kits which can be customized based on what makers want to make;
138
484892
4202
08:09
and a trading app.
139
489118
1532
08:10
We built the app specifically with the needs of the scrap dealers
140
490674
3692
08:14
in mind first,
141
494390
1421
08:15
because we realized that it was not enough to arm them with information
142
495835
4474
08:20
and upgraded technology
143
500333
1614
08:21
if we wanted them to green their recycling processes;
144
501971
3220
08:25
they needed incentives.
145
505215
1912
08:27
Scrap dealers are always looking for new scrap and new buyers
146
507151
3643
08:30
and what interests them is finding buyers who will pay more
147
510818
4181
08:35
for clean copper than for burnt.
148
515023
2365
08:38
We realized that in the entire ecosystem,
149
518213
2750
08:40
everyone was searching for something.
150
520987
2469
08:43
Makers are searching for materials, parts, components, tools, blueprints
151
523480
6044
08:49
to make what it is they want to make.
152
529548
2065
08:51
They're also finding a way to let customers and clientele
153
531962
3635
08:55
find out that they can repair a blender
154
535621
2191
08:57
or fix an iron
155
537836
1470
08:59
or, as we learned yesterday, to make a french fry machine.
156
539330
3253
09:03
On the flip side, you find that there are end users
157
543496
3286
09:06
that are desperately looking for someone that can make them a french fry machine,
158
546806
3918
09:10
and you have scrap dealers who are looking how they can collect this scrap,
159
550748
3713
09:14
process it, and turn it back into an input for new making.
160
554485
3952
09:18
We tried to untangle that knot of not knowing
161
558461
3042
09:21
to allow people to find what they need to make what they want to make.
162
561527
3431
09:24
We prototyped the makerspace kiosk in Agbogbloshie,
163
564982
3662
09:28
conceived as the opposite of a school:
164
568668
2798
09:31
a portal into experiential and experimental making
165
571490
3834
09:35
that connects local and global
166
575348
2077
09:37
and connects making with remaking and unmaking.
167
577449
3483
09:41
We made a rule that everything had to be made from scratch
168
581831
3304
09:45
using only materials made in Ghana
169
585159
2407
09:47
or sourced from the scrapyard.
170
587590
1864
09:50
The structures essentially are simple trusses which bolt together.
171
590136
4614
09:54
It takes about two hours to assemble one module with semi-skilled labor,
172
594774
4803
09:59
and by developing tooling and jigs and rigs,
173
599601
3114
10:02
we were able to actually build these standardized parts
174
602739
3543
10:06
within this ecosystem of artisanal welders
175
606306
3344
10:09
with the precision of one millimeter --
176
609674
1925
10:12
of course, using made-in-Agbogbloshie welding machines,
177
612637
3035
10:15
as well as for the tools,
178
615696
1443
10:17
which can lock, the toolboxes, and stack to make workbenches,
179
617163
3615
10:20
and again, customized based on what you want to make.
180
620802
2628
10:23
We've tested the app in Agbogbloshie
181
623827
3052
10:26
and are getting ready to open it up to other maker ecosystems.
182
626903
3496
10:30
In six months, we'll have finished three years of testing
183
630826
3689
10:34
the makerspace kiosk,
184
634539
1662
10:36
which I have to admit, we've subjected to some pretty horrific abuse.
185
636225
4097
10:40
But it's for a good cause,
186
640346
1929
10:42
because based on the results of that testing,
187
642299
2245
10:44
we've been able to redesign an upgraded version of this makerspace.
188
644568
5315
10:49
If a fab lab is large, expensive, and fixed in place,
189
649907
5619
10:55
think of this as the counterpoint:
190
655550
2024
10:58
something low-cost,
191
658273
1818
11:00
which can be locally manufactured,
192
660828
3163
11:04
which can be expanded and kitted out incrementally
193
664015
3595
11:07
as makers acquire resources.
194
667634
2295
11:09
You can think of it as a toolshed,
195
669953
2850
11:12
where makers can come and check out tools
196
672827
3125
11:15
and take them via handcart
197
675976
2362
11:18
to wherever they want in the city to make what it is they want to make.
198
678362

11:21
And moving into the next phase, we're planning to also add
199
681745
2947
11:24
ceiling-mounted CNC bots,
200
684716
2864
11:27
which allow makers to cocreate together with robots.
201
687604
3777
11:31
Ultimately, this is a kit of parts,
202
691405
2258
11:33
which can be assembled locally within the informal sector
203
693687
3369
11:37
using standardized parts
204
697080
1831
11:38
which can be upgraded collectively through an open-source process.
205
698935
3706
11:46
In totality, this entire makerspace system
206
706800
2367
11:49
tries to do five things:
207
709191
1714
11:50
to enable emerging makers to gather the resources they need
208
710929
5200
11:56
and the tools to make what they want to make;
209
716153
2164
11:58
to learn by doing and from others;
210
718341
2858
12:01
to produce more and better products;
211
721223
2971
12:04
to be able to trade to generate steady income;
212
724218
2724
12:06
and ultimately, to amplify not only their reputation as a maker,
213
726966
3837
12:10
but their maker potential.
214
730827
1550
12:13
Sankofa is one of the most powerful Adinkra symbols of the Akan peoples
215
733266
4528
12:17
in Ghana and Cote d'Ivoire,
216
737818
1348
12:19
and it can be represented as a bird reaching onto its back to collect an egg,
217
739190
5312
12:24
a symbol of power.
218
744526
1218
12:27
It translates literally from the Twi as "return and get it,"
219
747331
3138
12:30
and what this means is that if an individual or a community or a society
220
750493
4733
12:35
wants to have a successful future, they have to draw on the past.
221
755250
4756
12:40
To acquire and master existing ways of doing,
222
760030
3542
12:43
access the knowledge of their ancestors.
223
763596
2318
12:45
And this is very relevant
224
765938
1215
12:47
if we want to think about an inclusive future for Africa today.
225
767177
4386
12:51
We have to start from the ground up,
226
771587
2403
12:54
mining what already works for methods and for models,
227
774014
4003
12:58
and to think about how might we be able to connect,
228
778041
4132
13:02
in a kind of "both-and," not "either-or" paradigm,
229
782197
4112
13:06
the innovation capacity of this growing network
230
786333
3586
13:09
of tech hubs and incubators across the continent
231
789943
3245
13:13
and to rethink beyond national boundaries and political boundaries,
232
793212
4591
13:17
to think about how we can network innovation in Africa
233
797827
4290
13:22
with the spirit of Sankofa
234
802141
2519
13:24
and the existing capacity of makers at the grassroots.
235
804684
4444
13:30
If, in the future, someone tells you
236
810033
1788
13:31
Agbogbloshie is the largest e-waste dump in the world,
237
811845
3540
13:35
I hope you can correct them
238
815409
2232
13:37
and explain to them that a dump is a place where you throw things away
239
817665
4544
13:42
and leave them forever;
240
822233
1368
13:43
a scrapyard is where you take things apart.
241
823625
2211
13:45
Waste is something that no longer has any value,
242
825860
3217
13:49
whereas scrap is something that you recover
243
829101
2634
13:51
specifically to use it to remake something new.
244
831759
3780
13:57
Making is a cycle,
245
837523
1407
13:59
and African makerspaces are already pioneering and leading
246
839676
5043
14:05
circular economy at the grassroots.
247
845969
2638
14:09
Let's make more and better together.
248
849128
2245
14:11
Thank you.
