Doctor is on
Pinto is directed general of a international rice research institute or irri for short based in the filpers
Here she explains more about the global popularity of rice to bbc world service program
The food chain between fifty and fifty six percent of the world's population rely on rice as the principal staple
Now that's roughly about four billion people
And it is one of those commodities
That is grown really extensively particularly in southeasia and southeeast asia
But increasingly the appetite for it is growing in continence like africa
And of course there are also let american and european rice varieties
Rice is a commodity
A produce that can be bought unsold like other crops
Rice has varieties different types for example brown rice
Long grained rice or baasmati much of the research interrice 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 to inks the worworld's populatheir each rise so there's a growing demand in africa and europe
Too so clearly there's an appetite
A strong desire for rice worworld wide
So is it possible to growriice in a new ecofriendly away
Led ygfully blabbert director of rice company tilder thinks the answer lies in a new growing technique called alternate wet druring or awd for short to grow rice
Farmers go through cycles of flooding their fields or padties
Which then dry out and need to be flooded
Too so cleard measuring pipes are thined fifteen centimeters underground
So that farmers can check water levels at any part of the each rice
嗯
有normally rice needs twenty five cycles of flooding and drawing out to grow
But using awd
This is reduced twenty cycles saving farmers water and reducing methane emissions
His young fililibabboard telling gwth alexander presenter of bbc world services
The the jae
How he began his awd experiment with farmers in india
没有一有没有没有没有证据
We've got last uh twelve hundred and city eight farmers on board
Applying this dwd technique to reduce um the overall methanemission
And how did you persuade those farmers to give it a go
That was quite challenging
Because obviously the main challenges the farmers
The appallenges to lose revenues
They need to see tanngible results at the end of the crop
That they are getting obbusity something better many indian farmers got on board with john phileps experiment
If you get on board with something you agreed the new teanof action and get involved in other words
You give it a that you try techsomething acsee if it works as it turned out the new technique produced tangible resuasts
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 amounts of rice yielded increased right nail isn't it time you revealed the answer to your question i asked how many letters of water i needed to grow just one kilogram of rice
The answer was three thousand to five thousand letters so thursy
But not as thursy as you thought
Okay
Let's recap the vocabulary
We've learned in this program starting with commodity a product like rice that can be brought 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
If you get on board and get involved were doing it to give it a go
Means to try doing something
And finally the adjective tangible means real and measurable once again our six minutes of it
