0:00:00.806,0:00:02.306
I would like to share with you today

0:00:02.306,0:00:04.460
a project that has changed how I approach

0:00:04.460,0:00:06.371
and practice architecture:

0:00:06.371,0:00:09.299
the Fez River Rehabilitation Project.

0:00:09.299,0:00:11.640
My hometown of Fez, Morocco,

0:00:11.640,0:00:15.307
boasts one of the largest walled[br]medieval cities in the world,

0:00:15.307,0:00:18.036
called Medina, nestled in a river valley.

0:00:18.046,0:00:21.634
The entire city is a UNESCO World Heritage Site.

0:00:21.634,0:00:25.610
Since the 1950s, as the[br]population of the Medina grew,

0:00:25.610,0:00:27.530
basic urban infrastructure

0:00:27.530,0:00:30.460
such as green open spaces and sewage

0:00:30.460,0:00:35.600
quickly changed and got highly stressed.

0:00:35.600,0:00:38.065
One of the biggest casualties of the situation

0:00:38.065,0:00:42.028
was the Fez River, which bisects[br]the Medina in its middle

0:00:42.028,0:00:45.000
and has been considered for many centuries

0:00:45.000,0:00:47.572
as the city's very soul.

0:00:47.572,0:00:49.720
In fact, one can witness the presence

0:00:49.720,0:00:53.170
of the river's extensive water network

0:00:53.170,0:00:54.451
all throughout the city,

0:00:54.451,0:00:58.072
in places such as private and public fountains.

0:00:58.072,0:01:01.921
Unfortunately, because of the pollution of the river,

0:01:01.921,0:01:04.357
it has been covered little by little

0:01:04.357,0:01:07.431
by concrete slabs since 1952.

0:01:07.431,0:01:10.859
This process of erasure was coupled

0:01:10.859,0:01:12.895
with the destruction of many houses

0:01:12.895,0:01:14.387
along the river banks

0:01:14.387,0:01:16.076
to be able to make machineries

0:01:16.076,0:01:21.150
enter the narrow pedestrian network of the Medina.

0:01:21.150,0:01:24.335
Those urban voids quickly became illegal parking

0:01:24.335,0:01:26.461
or trash yards.

0:01:26.461,0:01:28.430
Actually, the state of the river

0:01:28.430,0:01:31.535
before entering the Medina is pretty healthy.

0:01:31.535,0:01:33.830
Then pollution takes its toll,

0:01:33.830,0:01:36.249
mainly due to untreated sewage

0:01:36.249,0:01:40.280
and chemical dumping from crafts such as tanning.

0:01:40.280,0:01:42.640
At some point, I couldn't bear

0:01:42.640,0:01:43.785
the desecration of the river,

0:01:43.785,0:01:46.485
such an important part of my city,

0:01:46.485,0:01:48.296
and I decided to take action,

0:01:48.296,0:01:50.321
especially after I heard that the city

0:01:50.321,0:01:53.415
received a grant to divert sewage water

0:01:53.415,0:01:55.215
and to treat it.

0:01:55.215,0:01:56.992
With clean water, suddenly

0:01:56.992,0:01:59.467
the uncovering of the river became possible,

0:01:59.467,0:02:02.347
and with luck and actually a lot of pushing,

0:02:02.347,0:02:04.563
my partner Takako Tajima and I

0:02:04.563,0:02:07.994
were commissioned by the city to[br]work with a team of engineers

0:02:07.994,0:02:10.592
to uncover the river.

0:02:10.592,0:02:12.257
However, we were sneaky,

0:02:12.257,0:02:13.944
and we proposed more:

0:02:13.944,0:02:18.620
to convert riverbanks into pedestrian pathways,

0:02:18.620,0:02:20.640
and then to connect these pathways

0:02:20.640,0:02:21.853
back to the city fabric,

0:02:21.853,0:02:24.406
and finally to convert the urban voids

0:02:24.406,0:02:27.837
along the riverbanks into public spaces

0:02:27.837,0:02:30.537
that are lacking in the Medina of Fez.

0:02:30.537,0:02:31.954
I will show you briefly now

0:02:31.954,0:02:35.251
two of these public spaces.

0:02:35.251,0:02:37.771
The first one is el-Rcif Plaza,

0:02:37.771,0:02:40.853
which sits actually right on top of the river,

0:02:40.853,0:02:43.890
which you can see here in dotted lines.

0:02:43.890,0:02:47.557
This plaza used to be a chaotic transportation hub

0:02:47.557,0:02:49.481
that actually compromised the urban integrity

0:02:49.481,0:02:51.849
of the Medina, that has the larger

0:02:51.849,0:02:54.448
pedestrian network in the world.

0:02:54.448,0:02:57.553
And right beyond the historic[br]bridge that you can see here,

0:02:57.553,0:02:59.364
right next to the plaza,

0:02:59.364,0:03:01.524
you can see that the river looked like

0:03:01.524,0:03:03.785
a river of trash.

0:03:03.785,0:03:06.237
Instead, what we proposed is to make

0:03:06.237,0:03:08.375
the plaza entirely pedestrian,

0:03:08.375,0:03:11.288
to cover it with recycled leather canopies,

0:03:11.288,0:03:15.030
and to connect it to the banks of the river.

0:03:15.030,0:03:16.914
The second site of intervention

0:03:16.914,0:03:20.190
is also an urban void along the river banks,

0:03:20.190,0:03:22.437
and it used to be an illegal parking,

0:03:22.437,0:03:24.192
and we proposed it to transform it

0:03:24.192,0:03:27.387
into the first playground in the Medina.

0:03:27.387,0:03:30.525
The playground is constructed using recycled tires

0:03:30.525,0:03:33.360
and also is coupled with a constructed wetland

0:03:33.360,0:03:35.790
that not only cleans the water of the river

0:03:35.790,0:03:39.381
but also retains it when floods occur.

0:03:39.381,0:03:42.542
As the project progressed and[br]received several design awards,

0:03:42.542,0:03:44.680
new stakeholders intervened

0:03:44.680,0:03:48.458
and changed the project goals and design.

0:03:48.458,0:03:51.560
The only way for us to be able to bring

0:03:51.560,0:03:54.532
the main goals of the project ahead

0:03:54.532,0:03:56.962
was for us to do something very unusual

0:03:56.962,0:03:58.874
that usually architects don't do.

0:03:58.874,0:04:02.126
It was for us to take our design ego

0:04:02.126,0:04:03.892
and our sense of authorship

0:04:03.892,0:04:05.736
and put it in the backseat

0:04:05.736,0:04:08.245
and to focus mainly on being activists

0:04:08.245,0:04:10.450
and on trying to coalesce

0:04:10.450,0:04:12.441
all of the agendas of stakeholders

0:04:12.441,0:04:15.264
and focus on the main goals of the project;

0:04:15.264,0:04:17.796
that is, to uncover the river, treat its water,

0:04:17.796,0:04:20.680
and provide public spaces for all.

0:04:20.680,0:04:21.812
We were actually very lucky,

0:04:21.812,0:04:23.825
and many of those goals happened

0:04:23.825,0:04:25.738
or are in the process of happening.

0:04:25.738,0:04:27.898
Like, you can see here el-Rcif Plaza.

0:04:27.898,0:04:30.429
This is how it looked like about six years ago.

0:04:30.429,0:04:32.251
This is how it looks like today.

0:04:32.251,0:04:33.983
It's still under construction,

0:04:33.983,0:04:35.660
but actually it is heavily used

0:04:35.660,0:04:37.403
by the local population.

0:04:37.403,0:04:39.946
And finally, this is how el-Rcif Plaza will look like

0:04:39.946,0:04:41.971
when the project is completed.

0:04:41.971,0:04:45.829
This is the river, covered, used as a trash yard.

0:04:45.829,0:04:47.651
Then after many years of work,

0:04:47.651,0:04:50.385
the river with clean water, uncovered.

0:04:50.385,0:04:52.410
And finally, you can see here the river

0:04:52.410,0:04:54.851
when the project will be completed.

0:04:54.851,0:04:57.292
So for sure, the Fez River Rehabilitation

0:04:57.292,0:04:59.710
will keep on changing and adapting

0:04:59.710,0:05:01.938
to the sociopolitical landscape of the city,

0:05:01.938,0:05:04.998
but we strongly believe that by reimagining

0:05:04.998,0:05:07.439
the role and the agency of the architect,

0:05:07.439,0:05:11.398
we have set up the core idea[br]of the project into motion;

0:05:11.398,0:05:13.907
that is, to transform the river from sewage

0:05:13.907,0:05:15.561
to public space for all,

0:05:15.561,0:05:18.733
thereby making sure that the city of Fez

0:05:18.733,0:05:21.970
will remain a living city for its inhabitants

0:05:21.970,0:05:23.120
rather than a mummified heritage.

0:05:23.120,0:05:24.856
Thank you very much.

0:05:24.856,0:05:25.775
(Applause)
