BBC: Should we eat less rice? -2

We've got, last year, 1,268 farmers on board applying this AWD technique to reduce the overall methane emission. 

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

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

Many Indian farmers got on board with Jean-Philipe'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 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...Right, Neil, isn't it time you revealed the answer to your question?

I asked how many litres of water are needed to grow just 1 kilogram of rice, and the answer was 3,000 to 5,000 litres so thirsty, but not as thirsty as you thought.

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. 

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 wiht doing it.

To give it a go means to try doing something. 

And finally, the adjective tangible means real and measurable.
