Hello, this is 6 Minute English from BBC Learning English.
2
I'm Neil.
3
And I'm Beth.
4
Neil, what type of foods do you often eat?
5
Well, basic things to fill me up.
6
That's sort of bread, potatoes...
7
Well, food like this, which is regularly eaten by many people, is known as a staple.
8
In Britain, bread is a popular staple, but for large parts of the world there's another food which is number one – rice.
9
That's right.
10
Over half the world's population eats rice as the staple food, especially in Asia.
11
But rice is a very thirsty crop which needs lots of water to grow, and this is becoming a problem because of droughts and flooding caused by climate change.
12
In this programme, we'll be hearing about a pioneering new technique – helping farmers to grow rice in the face of a changing climate.
13
As usual, we'll be learning some useful new words and phrases.
14
And remember, you can find all the vocabulary from this programme on our website, bbclearningenglish.com.
15
But first I have a question for you, Beth.
16
Just now I mentioned that rice is a very thirsty crop.
17
So, how much water is needed to grow one kilogram of rice?
18
Is it a 1,000 to 3,000 litres, b 3,000 to 5,000 litres, or c 5,000 to 7,000 litres?
19
I'm going to say C – 5,000 to 7,000 litres.
20
Well, we'll find out if that's right at the end of the programme.
21
Dr Yvonne Pinto is Director General of the International Rice Research Institute, or IRRI for short, based in the Philippines.
22
Here, she explains more about the global popularity of rice to BBC World Service programme, The Food Chain.
23
Between 50 and 56 per cent of the world's population rely on rice as the principal staple.
24
Now that's roughly about 4 billion people and it is one of those commodities that is grown really extensively,
25
particularly in South Asia and Southeast Asia, but increasingly the appetite for it is growing in continents like Africa and of course there are also Latin American and European rice varieties.
26
Rice is a commodity – a produce that can be bought and sold.
27
Like other crops, rice has varieties – different types.
28
For example, brown rice, long-grained rice or basmati.
29
Much of the research into rice today is focused on making new varieties that can adapt to the changing environment and grow in conditions of either too much or too little water.
30
Over half the world's population eats rice – and there's a growing demand in Africa and Europe too.
31
So clearly there's an appetite – a strong desire – for rice worldwide.
32
So is it possible to grow rice in a more eco-friendly way?
33
Jean-Philippe Laborde, director of rice company Tilda, thinks the answer lies in a new growing technique called Alternate Wet Drying, or AWD for short.
34
To grow rice, farmers go through cycles of flooding their fields, or paddies, which then dry out and need to be flooded again.
35
With AWD, measuring pipes are placed 15 centimetres underground so that farmers can check water levels at any part of the field.
36
Normally, rice needs 25 cycles of flooding and drying out to grow.
37
But using AWD, this is reduced to 20 cycles, saving farmers water and reducing methane emissions.
38
Here's Jean-Philippe Laborde telling Gruz Alexander, presenter of BBC World Service's The Food Chain, how he began his AWD experiment with farmers in India.
39
We've got last year 1,268 farmers on board applying this AWD technique to reduce the overall methane emission.
40
And how did you persuade those farmers to give it a go?
41
That was quite challenging because obviously the main challenge is for farmers, the apprehension to lose revenues.
42
They need to see tangible results at the end of the crop, that they are getting obviously something better.
43
Many Indian farmers got on board with Jean-Philippe's experiment.
44
If you get on board with something, you agree to a plan of action and get involved.
45
In other words, you give it a go.
46
You try doing something to see if it works.
47
As it turned out, the new technique produced tangible results – results which are real and measurable.
48
Using AWD, the amounts of water and electricity needed to grow rice decreased, methane gas emissions reduced and on top of that, the amount of rice yielded increased.
49
Right, Neil, isn't it time you revealed the answer to your question?
50
I asked how many litres of water are needed to grow just one kilogram of rice?
51
And the answer was 3,000 to 5,000 litres.
52
So thirsty, but not as thirsty as you thought.
53
OK, let's recap the vocabulary we've learned in this programme, starting with commodity, a product like rice that can be bought and sold.
54
Varieties of something are different types of it.
55
If there's an appetite for something, there's a strong desire or demand for it.
56
If you get on board with an idea or a plan, you agree to do something and get involved with doing it.
57
To give it a go means to try doing something.
58
And finally, the adjective tangible means real and measurable.
59
Once again, our six minutes are up.

練習のコツ
この動画では、自然な会話のスピードで話されています。自分のペースで繰り返し練習するために、shadow speechの技術を使いましょう。まずは動画を観ながらリスニングをし、理解した内容を声に出して復唱します。言葉のリズムやイントネーションに注目することで、英語の発音を良くする助けになります。また、YouTubeで英語学習として活用することで、様々なトピックに触れることができます。特に、IELTS スピーキング対策としても有効です。自信を持って話せるようになるために、少しずつ声に出して練習を続けましょう。
シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
