New flood-resistant rice offers hope to Bangladeshi farmers
|
A new strain of rice may
be able to resist floods that destroy vast tracts of paddy fields in
Bangladesh each year, offering hope to millions of poor farmers,
researchers say.
The farmers lose their rice crops when fields are submerged by annual
floods triggered when rivers, fed by heavy monsoon rains and melting
Himalayan glaciers, burst their banks. |

The rice type, called Swarna
Submergence 1, developed by the Manila-based International Rice Research
Institute (IRRI), proved to be flood resistant in trials this year in northern
Bangladesh, researchers said.
Normal rice varieties cannot survive being submerged by flood water for more
than three days, resulting in huge losses for farmers.
But "last month when the flood water receded from two farms in which Swarna
Sub-1 was planted, we saw the rice paddy stand up again, 10 days after it was
completely submerged by water," said senior researcher Abdul Mazid.
"It was simply amazing. It means the variety has proved flood-resistant. It
could be a huge step towards helping millions of rice farmers who are made
paupers by floods," said Mazid of the Bangladesh Rice Research Institute (BRRI).
Low-lying Bangladesh, criss-crossed by 230 rivers, experiences flooding every
year. Experts say the floods are one of the main reasons why 40 percent of the
country's 140 million population live in dire poverty.
Rice production accounts for 14 per cent of Bangladesh's gross domestic product.
Some two-thirds of Bangladesh's 144 million population directly or indirectly
derive their living from rice farming.
"If the flood water stays two to three days, it is a blessing. It nourishes the
soils. But if it stays longer, it destroys the crops," said IRRI liaison
scientist Hamid Mia.
This year alone rice worth 290 million dollars was damaged in one the worst
floods in nearly a decade in July, according to preliminary estimates.
The government said the losses would climb following a second spell of flooding
in early September that has submerged more than a third of the country.
Swarna Sub-1 was invented in 2004 after IRRI researchers implanted a
submergence-resistant gene in a massively popular high-yielding Indian rice
variety through conventional breeding.
"The idea was to give the farmers a variety that can survive flood water for 10
to 17 days while at the same time ensuring them a more than average yield," said
Mia.
With support from Swiss charity Inter Corp, BRRI distributed seeds and seedlings
of the submergence-resistant rice variety to 114 farmers across nine districts
in the country.
"The field tests have so far yielded very good results. The farmers are excited
and want more seeds and seedlings," said Mazid.
"Next year, we will quadruple the number of testing farms. And hopefully, by
2009-2010, we can start commercial production of the flood-resistant rice," he
added.
