Cholera was reported in Haiti

2000
ハイチでは昨年10月に
00:17
for the first time in over 50 years
1
2000
2000
ここ50年で初となる
00:19
last October.
2
4000
2000
コレラが確認されました
00:21
There was no way to predict
3
6000
2000
水を介してどれ程拡大するのか
00:23
how far it would spread through water supplies
4
8000
3000
どれ程状況が悪化するのかを
00:26
and how bad the situation would get.
5
11000
3000
予測する手段はありませんでした
00:29
And not knowing where help was needed
6
14000
2000
援助の必要な場所を特定できなければ
00:31
always ensured that help was in short supply
7
16000
3000
必然的に援助が必要な地域では
00:34
in the areas that needed it most.
8
19000
3000
物資の不足という自体が生じます
00:37
We've gotten good at predicting and preparing for storms
9
22000
3000
嵐の予測はだいぶ進んでおり
00:40
before they take innocent lives
10
25000
2000
取り返しのつかない被害がでる前に
00:42
and cause irreversible damage,
11
27000
2000
対策をとることができます
00:44
but we still can't do that with water,
12
29000
2000
水に関してはこれができないのです
00:46
and here's why.
13
31000
2000
理由はこうです
00:48
Right now, if you want to test water in the field,
14
33000
2000
現在 水質調査には
00:50
you need a trained technician,
15
35000
2000
訓練を受けた技術者と
00:52
expensive equipment like this,
16
37000
2000
高価な機器が必要です
00:54
and you have to wait about a day
17
39000
2000
更に結果が出るまでに
00:56
for chemical reactions to take place and provide results.
18
41000
3000
化学変化が起こるのを１日弱待たなくてはいけません
00:59
It's too slow
19
44000
2000
調査が必要な場所全ての
01:01
to get a picture of conditions on the ground
20
46000
2000
水質状況を把握するには
01:03
before they change,
21
48000
2000
時間が掛かりすぎる上に
01:05
too expensive to implement
22
50000
2000
水質が変ってしまう可能性もあります
01:07
in all the places that require testing.
23
52000
2000
更に費用もかなり高額です
01:09
And it ignores the fact that, in the meanwhile,
24
54000
2000
真っ先に必要な飲み水の確保が
01:11
people still need to drink water.
25
56000
2000
二の次にされてしまっているのです
01:13
Most of the information that we collected on the cholera outbreak
26
58000
3000
私たちはコレラ流行の情報の大半を
01:16
didn't come from testing water;
27
61000
2000
水質調査以外から入手しました
01:18
it came from forms like this,
28
63000
2000
このような用紙を使用して
01:20
which documented all the people
29
65000
2000
支援を受けられなかった人々から
01:22
we failed to help.
30
67000
2000
情報をとりました
01:24
Countless lives have been saved
31
69000
2000
炭鉱では数え切れないほどの
01:26
by canaries in coalmines --
32
71000
2000
人命を救ったのはカナリアでした
01:28
a simple and invaluable way
33
73000
2000
鉱夫が炭鉱の安全を確認するための
01:30
for miners to know whether they're safe.
34
75000
2000
シンプルですが重要な手段です
01:32
I've been inspired by that simplicity as I've been working on this problem
35
77000
3000
私はこの単純さに感銘を受けて 私の知る
01:35
with some of the most hardworking and brilliant people I've ever known.
36
80000
3000
最高の仲間たちとこの問題解決に取り組んできました
01:38
We think there's a simpler solution to this problem --
37
83000
2000
解決策は日常的に水質調査を
01:40
one that can be used
38
85000
2000
必要とする場所に暮らす人々が
01:42
by people who face conditions like this everyday.
39
87000
2000
使える単純な装置でした
01:44
It's in its early stages,
40
89000
2000
これはまだ初期段階のものですが
01:46
but this is what it looks like right now.
41
91000
3000
今からお見せします
01:49
We call it the Water Canary.
42
94000
2000
ウォーターカナリアと呼んでいます
01:51
It's a fast, cheap device
43
96000
3000
「この水は汚染されているか否か？」という
01:54
that answers an important question:
44
99000
2000
重要な問いに即座に答えてくれる
01:56
Is this water contaminated?
45
101000
2000
安価なデバイスです
01:58
It doesn't require any special training.
46
103000
3000
特別な訓練は一切必要ありません
02:01
And instead of waiting for chemical reactions to take place,
47
106000
3000
このデバイスは光を利用しているため
02:04
it uses light.
48
109000
2000
化学反応を待つ必要もありません
02:06
That means there's no waiting
49
111000
2000
つまり このデバイスがあれば
02:08
for chemical reactions to take place,
50
113000
2000
化学反応を待たずに
02:10
no need to use reagents that can run out
51
115000
2000
試薬も使わず
02:12
and no need to be an expert
52
117000
2000
専門家がいなくても
02:14
to get actionable information.
53
119000
3000
必要な情報が手に入るのです
02:17
To test water, you simply insert a sample
54
122000
2000
使い方はサンプルを入れるだけです
02:19
and, within seconds,
55
124000
2000
数秒後には
02:21
it either displays a red light, indicating contaminated water,
56
126000
3000
汚染を示す赤色か安全を示す
02:24
or a green light, indicating the sample is safe.
57
129000
2000
緑色のランプが点灯します
02:26
This will make it possible
58
131000
2000
このデバイスがあれば
02:28
for anyone to collect life-saving information
59
133000
3000
誰もが人命に関わる情報を得られるだけでなく
02:31
and to monitor water quality conditions as they unfold.
60
136000
3000
変わりゆく水質の監視も行うことができます
02:34
We're also, on top of that,
61
139000
3000
加えて
02:37
integrating wireless networking
62
142000
3000
このデバイスには
02:40
into an affordable device
63
145000
2000
GPSとGSMが
02:42
with GPS and GSM.
64
147000
2000
組み込まれているので
02:44
What that means is that each reading can be automatically transmitted to servers
65
149000
3000
リアルタイムでサーバーに情報を転送し
02:47
to be mapped in real time.
66
152000
2000
地図上に表示することもできます
02:49
With enough users,
67
154000
2000
十分な利用者が集まれば
02:51
maps like this will make it possible
68
156000
2000
このような地図を作成することで
02:53
to take preventive action,
69
158000
2000
復興に何年もかかるような
02:55
containing hazards before they turn into emergencies
70
160000
3000
緊急事態に陥る前に
02:58
that take years to recover from.
71
163000
2000
対策をとることもできるでしょう
03:00
And then, instead of taking days
72
165000
2000
情報は自動で送信されるので
03:02
to disseminate this information to the people who need it most,
73
167000
2000
情報を必要とする人々に向けて
03:04
it can happen automatically.
74
169000
3000
時間をかけて手動で送信する必要もありません
03:07
We've seen how distributed networks,
75
172000
2000
分散ネットワークや
03:09
big data and information
76
174000
2000
大容量データ 情報には
03:11
can transform society.
77
176000
2000
社会を変える力があります
03:13
I think it's time for us to apply them to water.
78
178000
3000
今こそ これを水にも適用する時なんです
03:16
Our goal over the next year is to get Water Canary ready for the field
79
181000
2000
次の目標はウォーターカナリアを
03:18
and to open-source the hardware
80
183000
2000
オープンソース化し 誰もが
03:20
so that anyone can contribute to the development and the evaluation,
81
185000
3000
改善・進化の一端を担うことができる環境を作り
03:23
so we can tackle this problem together.
82
188000
2000
共同で問題解決に取り組んでいくことです
03:25
Thank you.
83
190000
2000
ありがとうございました
03:27
(Applause)
84
192000

ABOUT THE SPEAKER
Sonaar Luthra -Sonaar Luthra is the creator of Water Canary, a water-testing device that collects real-time water-quality data from the field.
Why you should listen
Sonaar Luthra was a writer and educator when he enrolled in NYU's famed Interactive Telecommunications Program (ITP) -- a breeding ground for cross-disciplinary thinking. He tells the TED Blog what happened next:
"I wanted to come up with some way of becoming what I was calling an 'urban planner for the global village.' And ... I fell in love with circuitry and with making tangible objects that had real functionality. Next thing I knew, I found myself in a class called Design for UNICEF, taught by Clay Shirky in association with UNICEF’s Innovations Lab.
"I wanted to see what was possible with water, and I was lucky to have an incredible team and the support of faculty that were willing to take on such a huge challenge. We started off as novices but we all became water experts in the process."
