BBC 6分钟英语 我们应该少吃米饭吗

Hello. This is six minute English from BBC.

Learning

English. I'm Neil, and I'm Beth Neil.

What type of foods do you often eat?

Well, basic things to fill me up.

That sort of bread. Potatoes. Well, food like this, which is regularly eaten by many people, is known as a

staple. In Britain, bread is a popular staple.

But for large parts of the world, there's another food, which is number one rice.

That's right. Over half the world's population eats rice as the staple food, especially in Asia.

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.

In this program, will be hearing about a pioneering new technique helping farmers to grow rice in the face of a changing climate.

As usual, we'll be learning some useful new words and phrases.

And remember, you can find all the vocabulary from this program on our website, bbc learning english dot com.

But 1st, I have a question for you, beth.

Just now, I mention that rice is a very thirsty crop.

So how much water is needed to grow 1 kg.

Of rice? Is it? A-A thousand to 3000 liters.

B 3000 to 5000 liters, or C, 5000 to 7000 liters?

Um, I'm going to say, see, 5000 to 7000 liters.

Well, we'll find out if that's right at the end of the program.

Doctor Ivon Pinto is Director General of the International Rice Research Institute, or I-R-R-I, for short, based in the Philippines.

Here she explains more about the global popularity of rice to BBC World Service program the food chain.

Between 50 and 56% of the world's population rely on rice as the principal staple.

Now, that's roughly about 4 billion people.

And it is one of those commodities that is grown really extensively, 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.

Rice is a commodity, a produce that can be bought and sold like other crops.

Rice has varieties, different types, e.g.

brown rice, long grained rice, or basmetti.

Much of the research into rice today is focused on making new verieties that can adapt to the changing environment and grow in conditions of either too much or too little water.

Over half the world's population eats rice, and there's a growing demand in Africa and Europe too.

So clearly there's an appetite, a strong desire, for rice worldwide.

So is it possible to grow rice in a more eco friendly way?

Jean Philippe Blubbard, director of rice company Tilder, thinks the answer lies in a new growing technique called alternate Wet drying, or a WD, for short.

To grow rice, farmers go through cycles of flooding their fields or paddies, which then dry out and need to be flooded again.

with a WD. Measuring pipes are placed 15 cm underground so that farmers can check water levels at any part of the field.

Normally, rice needs 25 cycles of flooding and drying out to grow.

But using a WD, this is reduced to 20 cycles, saving farmers water and reducing methane emissions.

Here's Jean Felipe Laboard telling Ruth Alexander, presenter of BBC World Services, the food chain, how he began his AWD experiment with farmers in India.

We've got, last year, twelve hundred and 68 farmers on board applying this edible technique to reduce the overall metanimation.

And how did you persuade those farmers to give it a go?

That was quite challenging, because obviously the main challenge is for farmers the apprehension to lose revenues, they need to see tangible results at the end of the crop that they are getting obviously something better.

Many Indian farmers got on board with John philippe's experiment.

If you get on board with something, you agree to a plan of action and get involved.

In other words, you give it a go.

You try doing something to see if it works.

As it turned out, the new technique produced tangible results, results which are real and measurable.

Using a WD, 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.

Rights neil. Isn't it time you revealed the answer to your question?

I asked How many liters of water I needed to grow just 1 kg.

Of rice? And the answer was 3000 to 5000 liters.

So thirsty, but not as thirsty as you thought.

OK, let's recap the vocabulary we've learned in this program, starting with commodity, a product like rice that can be bought and sold.

Varieties of something are different types of it.

If there's an appetite

for something, there's a strong desire or demand for it, if you get on board with an idea or a plan, you agree to do something and get involved with doing it.

To give it a go means to try doing something.

And finally, the adjective tangible means real and measurable.
