建築師 Kate Orff 以牡蠣作為都市變遷的一個媒介。她提出"蚵築"的想法，將牡蠣聚集成一個結構物，再把它沉入都市河川之中，讓牡蠣將水中的污染物處理乾淨，將惡名昭彰的髒水淨化。Orff 分享她對都市景觀的願景，一個將自然與人的共同利益聯結在一起的未來。

I am passionate about the American landscape
0
1000
3000
我熱愛美國景觀
00:19
and how the physical form of the land,
1
4000
2000
還有地形
00:21
from the great Central Valley of California
2
6000
2000
從加州的中央谷地
00:23
to the bedrock of Manhattan,
3
8000
2000
到曼哈頓的岩盤
00:25
has really shaped our history and our character.
4
10000
3000
他們如何的形塑了我們的歷史與特質
00:28
But one thing is clear.
5
13000
2000
不過，我們可以非常清楚的看到
00:30
In the last 100 years alone,
6
15000
2000
在過去的100年裡
00:32
our country -- and this is a sprawl map of America --
7
17000
3000
我們的國家 -- 這張地圖顯示了美國城市的擴張
00:35
our country has systematically
8
20000
3000
我們的國家已經有系統的
00:38
flattened and homogenized the landscape
9
23000
2000
將景觀扁平化與均質化
00:40
to the point where we've forgotten
10
25000
2000
以至於我們忘記了
00:42
our relationship with the plants and animals
11
27000
2000
與我們同住在一起的動植物
00:44
that live alongside us
12
29000
2000
還有在我們腳底下的泥土
00:46
and the dirt beneath our feet.
13
31000
2000
跟我們之間的關係
00:48
And so, how I see my work contributing
14
33000
2000
所以我把我的作品定位
00:50
is sort of trying to literally re-imagine these connections
15
35000
3000
看作是試圖對這些連結作重新的想像
00:53
and physically rebuild them.
16
38000
2000
並且實質上將它重新建造出來
00:55
This graph represents what we're dealing with now
17
40000
3000
此張圖代表我們目前
00:58
in the built environment.
18
43000
2000
人造環境正遇到的處境
01:00
And it's really a conflux
19
45000
2000
他實際上是一個
01:02
of urban population rising,
20
47000
2000
城市人口增加
01:04
biodiversity plummeting
21
49000
2000
生物多樣性急劇下降
01:06
and also, of course, sea levels rising
22
51000
3000
還有海平面上升
01:09
and climate changing.
23
54000
2000
和氣候變化的匯流
01:11
So when I also think about design,
24
56000
2000
因此，當我在作設計思考時
01:13
I think about
25
58000
2000
我會想嘗試
01:15
trying to rework and re-engage
26
60000
2000
將這個圖上的線條
01:17
the lines on this graph
27
62000
3000
以更有建設性的方式
01:20
in a more productive way.
28
65000
2000
重新連結
01:22
And you can see from the arrow here
29
67000
2000
這個的箭頭
01:24
indicating "you are here,"
30
69000
2000
標示你們目前所在的位置
01:26
I'm trying to sort of blend and meld
31
71000
2000
我有點想將都市主義
01:28
these two very divergent fields
32
73000
2000
與生態這兩個非常不同的領域
01:30
of urbanism and ecology,
33
75000
2000
混合和融合在一起
01:32
and sort of bring them together in an exciting new way.
34
77000
3000
用一個令人興奮的新方法加以整合
01:36
So the era of big infrastructure is over.
35
81000
4000
龐大基礎設施的時代已經結束
01:40
I mean, these sort of top-down,
36
85000
2000
我的意思是，這些自上而下的
01:42
mono-functional, capital-intensive solutions
37
87000
2000
單一功能，資本密集型的解決方案
01:44
are really not going to cut it.
38
89000
2000
已經不足以解決問題
01:46
We need new tools and new approaches.
39
91000
3000
我們需要新的工具和新方法
01:49
Similarly, the idea of architecture
40
94000
2000
同樣的，把建築物
01:51
as this sort of object in the field,
41
96000
2000
當作是個與周邊毫無關係的
01:53
devoid of context,
42
98000
2000
獨立物件的這種想法
01:55
is really not the --
43
100000
2000
實在不是
01:57
excuse me, it's fairly blatant --
44
102000
2000
抱歉，這個作品實在是有夠直接
01:59
is really not the approach
45
104000
3000
實在不是
02:02
that we need to take.
46
107000
2000
解決問題的辦法
02:04
So we need new stories,
47
109000
2000
我們需要新的故事
02:06
new heroes and new tools.
48
111000
3000
新的英雄和新的工具
02:09
So now I want to introduce you to my new hero
49
114000
3000
所以，現在我想向你們介紹
02:12
in the global climate change war,
50
117000
2000
我在全球氣候變遷戰爭中的新英雄
02:14
and that is the eastern oyster.
51
119000
2000
東方牡蠣
02:16
So, albeit a very small creature
52
121000
2000
儘管這種小動物
02:18
and very modest,
53
123000
2000
看上去不太起眼
02:20
this creature is incredible,
54
125000
2000
他其實非常不可思議
02:22
because it can agglomerate
55
127000
2000
因為它可以聚集成
02:24
into these mega-reef structures.
56
129000
2000
這些大型的礁堡結構
02:26
It can grow; you can grow it;
57
131000
2000
它會生長，你也可以養殖
02:28
and -- did I mention? -- it's quite tasty.
58
133000
3000
還有，我有沒有提到，它相當可口
02:31
So the oyster was the basis
59
136000
2000
因此，牡蠣就成了
02:33
for a manifesto-like urban design project
60
138000
3000
我在紐約港作的一個近乎宣言式的
02:36
that I did about the New York Harbor
61
141000
2000
都市設計案的主題
02:38
called "oyster-tecture."
62
143000
2000
我把這設計命題為“蚵築”
02:40
And the core idea of oyster-tecture is to harness the biological power
63
145000
3000
蚵築的核心思想，就是運用
02:43
of mussels, eelgrass and oysters --
64
148000
3000
貽貝、大葉藻和牡蠣等等
02:46
species that live in the harbor --
65
151000
2000
生活在海港裡的物種
02:48
and, at the same time,
66
153000
2000
的生物能
02:50
harness the power of people
67
155000
2000
同時運用
02:52
who live in the community
68
157000
2000
社區居民的力量
02:54
towards making change now.
69
159000
3000
現在就開始做些改變
02:57
Here's a map of my city, New York City,
70
162000
3000
這是我的城市，也就是紐約市的地圖
03:00
showing inundation in red.
71
165000
2000
紅色表示淹沒區
03:02
And what's circled is the site that I'm going to talk about,
72
167000
2000
圈起來的就是我要談的基地位置
03:04
the Gowanus Canal and Governors Island.
73
169000
3000
Gowanus運河和總督島(Governors Island)
03:07
If you look here at this map,
74
172000
2000
如果你看這邊這張地圖
03:09
showing everything in blue
75
174000
2000
藍色
03:11
is out in the water,
76
176000
2000
代表水
03:13
and everything in yellow is upland.
77
178000
2000
黃色代表陸地
03:15
But you can see, even just intuit, from this map,
78
180000
3000
即使只是直觀上看這張地圖
03:18
that the harbor has dredged and flattened,
79
183000
3000
你都可以看出海港經歷過疏通並整成平地
03:21
and went from a rich, three-dimensional mosaic to flat muck
80
186000
3000
在幾年之內從一個多樣、立體的鑲嵌體
03:24
in really a matter of years.
81
189000
3000
變成一個平坦的淤泥地
03:27
Another set of views of actually the Gowanus Canal itself.
82
192000
3000
另外就是Gowanus運河本身
03:30
Now the Gowanus is particularly smelly -- I will admit it.
83
195000
3000
目前 Gowanus運河非常臭，這點我不得不承認
03:33
There are problems of sewage overflow
84
198000
2000
運河裡有污水排入
03:35
and contamination,
85
200000
2000
與污染的問題
03:37
but I would also argue that almost every city
86
202000
3000
不過我認為幾乎每個城市
03:40
has this exact condition,
87
205000
2000
都有同樣的問題
03:42
and it's a condition that we're all facing.
88
207000
2000
這是一個我們共同面對的問題
03:44
And here's a map of that condition,
89
209000
2000
這地圖顯示了污染的狀況
03:46
showing the contaminants in yellow and green,
90
211000
3000
污染物以黃色和綠色顯示
03:49
exacerbated by this new flow of
91
214000
2000
而最近雨水暴增
03:51
storm-surge and sea-level rise.
92
216000
2000
和海平面上升使得問題加劇
03:53
So we really had a lot to deal with.
93
218000
2000
所以我們真的有很多課題需要處理
03:55
When we started this project,
94
220000
2000
當我們開始這個設計案時
03:57
one of the core ideas was to look back in history
95
222000
3000
核心思想之一就是回顧歷史
04:00
and try to understand what was there.
96
225000
2000
試圖了解這裡的過去
04:02
And you can see from this map,
97
227000
2000
你可以從這張舊地圖看到
04:04
there's this incredible geographical signature
98
229000
2000
當時在海港裡有好多
04:06
of a series of islands
99
231000
2000
不可思議的地理特徵
04:08
that were out in the harbor
100
233000
2000
包括一整系列的島嶼，
04:10
and a matrix of salt marshes and beaches
101
235000
3000
和整片可以緩衝
04:13
that served as natural wave attenuation
102
238000
2000
浪潮沖蝕陸地
04:15
for the upland settlement.
103
240000
2000
的鹽沼和海灘
04:17
We also learned at this time
104
242000
2000
當時
04:19
that you could eat an oyster about the size of a dinner plate
105
244000
3000
你還能從Gowanus運河中
04:22
in the Gowanus Canal itself.
106
247000
3000
捕到跟餐盤一樣大的牡蠣
04:25
So our concept is really this back-to-the-future concept,
107
250000
3000
所以我們的設計概念基本上就是要回到未來
04:28
harnessing the intelligence of that land settlement pattern.
108
253000
3000
要善用這地景形成的智慧
04:31
And the idea has two core stages.
109
256000
2000
我們的設計概念有兩個核心階段
04:33
One is to develop a new artificial ecology,
110
258000
3000
第一階段是要在海港裡建造一個
04:36
a reef out in the harbor,
111
261000
2000
新的人工生態珊瑚礁
04:38
that would then protect new settlement patterns
112
263000
2000
然後靠這個珊瑚礁保護內陸
04:40
inland and the Gowanus.
113
265000
2000
和Gowanus運河上的居民
04:42
Because if you have cleaner water and slower water,
114
267000
2000
因為如果你有流速較慢和較乾淨的水
04:44
you can imagine a new way of living with that water.
115
269000
3000
就可以重新想像人與水共同生活的新方法
04:47
So the project really addresses these three core issues
116
272000
3000
所以，我認為這個計畫是用一種新的和令人興奮的方式解決
04:50
in a new and exciting way, I think.
117
275000
3000
這三個核心課題：水質、河水暴漲、和海平面上升
04:53
Here we are, back to our hero, the oyster.
118
278000
3000
第一項，要回到我們的英雄：牡蠣
04:56
And again, it's this incredibly exciting animal.
119
281000
3000
它實在是個非常令人興奮的動物
04:59
It accepts algae and detritus in one end,
120
284000
2000
它從這一端接受藻類和有機碎屑
05:01
and through this beautiful, glamorous
121
286000
2000
通過這套美麗動人的
05:03
set of stomach organs,
122
288000
2000
消化系統
05:05
out the other end comes cleaner water.
123
290000
3000
另一端就跑出乾淨的水
05:08
And one oyster can filter up to 50 gallons of water a day.
124
293000
3000
一隻牡蠣一天可以過濾高達 50加侖的水
05:11
Oyster reefs also covered
125
296000
2000
牡蠣礁曾經占據
05:13
about a quarter of our harbor
126
298000
2000
這海港約四分之一的面積
05:15
and were capable of filtering water in the harbor in a matter of days.
127
300000
3000
幾天之內就可以把海港內的水過濾乾淨
05:18
They were key in our culture and our economy.
128
303000
4000
它們對我們的文化和經濟非常關鍵
05:22
Basically, New York was built
129
307000
2000
基本上，紐約市
05:24
on the backs of oystermen,
130
309000
2000
是靠牡蠣漁民創建的
05:26
and our streets were literally built over oyster shells.
131
311000
3000
而我們的街道也都真的建立在牡蠣殼上
05:29
This image
132
314000
2000
這張照片
05:31
is an image of an oyster cart,
133
316000
2000
是牡蠣攤
05:33
which is now as ubiquitous as the hotdog cart is today.
134
318000
3000
它當時就跟現在的熱狗攤一樣普遍
05:36
So again, we got the short end of the deal there.
135
321000
2000
這樣說起來，我們現在好像過得沒有當時好
05:38
(Laughter)
136
323000
2000
（笑聲）
05:40
Finally, oysters can attenuate
137
325000
2000
第二，牡蠣出生後
05:42
and agglomerate onto each other
138
327000
2000
會附著到老牡蠣的殼上
05:44
and form these amazing natural reef structures.
139
329000
3000
使得這些結構越長越大而終成天然的礁石構造
05:47
They really become nature's wave attenuators.
140
332000
3000
他們真的是大自然的消波塊
05:50
And they become the bedrock
141
335000
2000
第三，這些礁石也是
05:52
of any harbor ecosystem.
142
337000
2000
所有海港生態系統的基盤
05:54
Many, many species depend on them.
143
339000
2000
很多很多物種依賴他們生存
05:56
So we were inspired by the oyster,
144
341000
2000
我們從牡蠣身上得到靈感
05:58
but I was also inspired by the life cycle of the oyster.
145
343000
3000
也從牡蠣的生活史得到啟發
06:01
It can move from a fertilized egg
146
346000
3000
牡蠣從受精卵開始
06:04
to a spat, which is when they're floating through the water,
147
349000
3000
孵化成幼蟲後漂浮在水中
06:07
and when they're ready to attach onto another oyster,
148
352000
3000
然後在幾週後
06:10
to an adult male oyster or female oyster,
149
355000
2000
附著到另一個成熟的
06:12
in a number of weeks.
150
357000
3000
公或母牡蠣的殼上
06:15
We reinterpreted this life cycle
151
360000
2000
我們重新以人類視覺的尺度
06:17
on the scale of our sight
152
362000
2000
詮釋了這個生活史
06:19
and took the Gowanus
153
364000
2000
把Gowanus運河
06:21
as a giant oyster nursery
154
366000
2000
當作一個巨大的牡蠣的養殖場
06:23
where oysters would be grown up in the Gowanus,
155
368000
2000
讓牡蠣在運河裡孕育
06:25
then paraded down in their spat stage
156
370000
2000
在幼蟲期漂游過這些地方
06:27
and seeded out on the Bayridge Reef.
157
372000
3000
最後在 Bayridge Reef 這邊著床
06:30
And so the core idea here
158
375000
2000
設計的核心思想
06:32
was to hit the reset button
159
377000
2000
就像是按重新啟動鈕
06:34
and regenerate an ecology over time
160
379000
2000
隨著時間重新形成
06:36
that was regenerative and cleaning
161
381000
2000
一個可以再生、淨化、
06:38
and productive.
162
383000
2000
而且有生產力的生態系
06:40
How does the reef work? Well, it's very, very simple.
163
385000
3000
所以這珊瑚礁到底要怎麼弄？其實非常非常簡單。
06:43
A core concept here
164
388000
2000
核心概念就是
06:45
is that climate change
165
390000
2000
我們要如何因應
06:47
isn't something that --
166
392000
2000
氣候變遷
06:49
the answers won't land down from the Moon.
167
394000
3000
答案絕不會從天上掉下來
06:52
And with a $20 billion price tag,
168
397000
2000
況且有200億美元的價值
06:54
we should simply start and get to work with what we have now
169
399000
2000
我們實在應該就直接以我們現有的
06:56
and what's in front of us.
170
401000
2000
知識與資源開始工作
06:58
So this image is simply showing --
171
403000
2000
這張圖
07:00
it's a field of marine piles
172
405000
2000
是幾根海底樁
07:02
interconnected with this woven fuzzy rope.
173
407000
3000
用毛茸茸的繩索串連起來
07:05
What is fuzzy rope, you ask?
174
410000
3000
如果你要問：什麼是毛茸茸的繩索？
07:08
It's just that; it's this very inexpensive thing,
175
413000
3000
它就只是個很便宜的
07:11
available practically at your hardware store, and it's very cheap.
176
416000
3000
在五金店就買得到的東西
07:14
So we imagine that we would actually
177
419000
2000
所以，我們搞不好
07:16
potentially even host a bake sale
178
421000
2000
弄個糕餅義賣活動
07:18
to start our new project.
179
423000
2000
就可以湊足經費啟動我們的新計畫
07:20
(Laughter)
180
425000
2000
（笑聲）
07:22
So in the studio, rather than drawing,
181
427000
2000
所以在工作室裡，我們不是在繪圖
07:24
we began to learn how to knit.
182
429000
2000
而是開始學習如何編織
07:26
The concept was to really knit this rope together
183
431000
3000
我們的概念真的就是把這些繩子編織在一起
07:29
and develop this new soft infrastructure
184
434000
2000
發展出這個新的軟性基礎設施
07:31
for the oysters to grow on.
185
436000
2000
讓牡蠣可以在上面生長
07:33
You can see in the diagram how it grows over time
186
438000
3000
你可以在圖上看到它如何隨著時間成長
07:36
from an infrastructural space
187
441000
2000
從基礎設施慢慢發展成
07:38
into a new public urban space.
188
443000
3000
一個新的都市公共空間
07:41
And that grows over time dynamically
189
446000
3000
隨著時間，它的生長會
07:44
with the threat of climate change.
190
449000
2000
與氣候變遷的威脅作動態的回應
07:46
It also creates this incredibly interesting, I think,
191
451000
3000
它還可以創造一個非常有趣的
07:49
new amphibious public space,
192
454000
3000
新的兩棲公共空間
07:52
where you can imagine working,
193
457000
2000
在那裡你可以對工作
07:54
you can imagine recreating in a new way.
194
459000
3000
和休閒活動以嶄新的方式作些想像
07:57
In the end, what we realized we were making
195
462000
2000
到最後，我們發現我們其實是
07:59
was a new blue-green watery park
196
464000
3000
為下一個水很多的世紀
08:02
for the next watery century --
197
467000
2000
做了個新的藍綠水岸公園
08:04
an amphibious park, if you will.
198
469000
2000
一個兩棲公園
08:06
So get your Tevas on.
199
471000
2000
所以穿上你的水陸越野涼鞋
08:08
So you can imagine scuba diving here.
200
473000
2000
想像你在這裡潛水
08:10
This is an image of high school students,
201
475000
2000
這張圖是一群與我們團隊一起工作的
08:12
scuba divers that we worked with on our team.
202
477000
2000
高中學生，他們會水肺潛水
08:14
So you can imagine a sort of new manner of living
203
479000
3000
所以，你可以想像一個
08:17
with a new relationship with the water,
204
482000
2000
與水生活的新關係
08:19
and also a hybridizing of recreational and science programs
205
484000
3000
也可以把環境監測變成
08:22
in terms of monitoring.
206
487000
2000
休閒和科學的混合體
08:24
Another new vocabulary word for the brave new world:
207
489000
3000
我們為這個勇敢的新世界
08:27
this is the word "flupsy" --
208
492000
2000
創造了另一個新名詞：flupsy
08:29
it's short for "floating upwelling system."
209
494000
3000
它的是“漂浮湧升系統”的簡稱
08:32
And this glorious, readily available device
210
497000
3000
這個亮眼的、隨時可用的設施
08:35
is basically a floating raft
211
500000
2000
基本上就是一個漂浮平台
08:37
with an oyster nursery below.
212
502000
2000
下頭有個牡蠣孕育場
08:39
So the water is churned through this raft.
213
504000
3000
水會被送過這個平台的下方
08:42
You can see the eight chambers on the side
214
507000
2000
你可以看到側邊的八個小隔間
08:44
host little baby oysters and essentially force-feed them.
215
509000
3000
養育著小牡蠣，將水中的養分灌進他們嘴裡
08:47
So rather than having 10 oysters,
216
512000
3000
所以，10個牡蠣
08:50
you have 10,000 oysters.
217
515000
2000
不久就會變成10000個牡蠣
08:52
And then those spat are then seeded.
218
517000
2000
他們成熟後產卵孵出的幼蟲又會在這裡著床
08:54
Here's the Gowanus future
219
519000
2000
這就是我們想像Gowanus運河的未來
08:56
with the oyster rafts on the shorelines --
220
521000
2000
海岸線都是牡蠣平台
08:58
the flupsification of the Gowanus.
221
523000
3000
將整個Gowanus運河 “漂浮湧升化”
09:01
New word.
222
526000
2000
這是我們發明的新名詞
09:03
And also showing oyster gardening for the community
223
528000
3000
社區也可以在這邊緣
09:06
along its edges.
224
531000
2000
作牡蠣的養殖
09:08
And finally, how much fun it would be
225
533000
2000
想想看
09:10
to watch the flupsy parade
226
535000
2000
辦漂浮湧升遊行
09:12
and cheer on the oyster spats
227
537000
2000
為游泳著床的牡蠣幼蟲歡呼
09:14
as they go down to the reef.
228
539000
2000
將是多麼好玩的一件事
09:16
I get asked two questions about this project.
229
541000
3000
這個計畫我常被問兩個問題
09:19
One is: why isn't it happening now?
230
544000
2000
第一，為什麼到現在什麼都還看不出來？
09:21
And the second one is: when can we eat the oysters?
231
546000
3000
第二，我們什麼時候才能吃到牡蠣？
09:24
And the answer is: not yet, they're working.
232
549000
3000
答案是，還沒有，他們正在努力，但這得花些時間。
09:27
But we imagine, with our calculations,
233
552000
2000
不過根據我們的估算，
09:29
that by 2050,
234
554000
2000
大概到了2050年，
09:31
you might be able to sink your teeth into a Gowanus oyster.
235
556000
3000
你們就可以大啖Gowanus的牡蠣
09:34
To conclude, this is just one cross-section
236
559000
2000
總而言之，這只是一個城市
09:36
of one piece of city,
237
561000
2000
的一個小小的橫斷面
09:38
but my dream is, my hope is,
238
563000
2000
但我的夢想，我的希望是
09:40
that when you all go back to your own cities
239
565000
2000
當你們回到自己的城市
09:42
that we can start to work together and collaborate
240
567000
3000
我們可以開始攜手合作
09:45
on remaking and reforming
241
570000
2000
重新改造
09:47
a new urban landscape
242
572000
2000
一個新的都市景觀
09:49
towards a more sustainable, a more livable
243
574000
3000
讓它的未來更永續、更宜居
09:52
and a more delicious future.
244
577000
2000
還有更美味
09:54
Thank you.
245
579000
2000
謝謝
09:56
(Applause)
