Richard Opio dipped a
dirt-stained hand into the pinkish beans, marveling at the dramatic changes
they've made for his family. They used to harvest two sacks of normal beans;
now they take in six.
The
so-called "super bean," a fast-maturing, high-yield variety, is being
promoted by Uganda's government and agriculture experts amid efforts to feed
hunger-prone parts of Africa. It's also a step toward the next goal: the
"super, super bean" that researchers hope can be created. The beans
are produced by conventional genetic selection, not the contentious genetic
modification technologies.
The
beans that Opio now tends are thrilling farmers in this impoverished part of
northern Uganda that also strains under the recent arrival of more than 1
million refugees from its war-torn neighbor, South Sudan.
The
International Centre for Tropical Agriculture says the beans have been bred by
conventional means to resist the drought conditions that can lead to starvation
as arable land disappears.
The
group operates one of just two bean "gene banks" in Africa, which is
expected to be hit hardest by climate change even though the continent produces
less than 4% of the world's greenhouse gases, according to the U.N.
Development Programme.
One
"gene bank" is on the outskirts of Uganda's capital, Kampala, where
the beans that Opio now farms were bred. The other is in Malawi in southern
Africa. Beans kept at the two banks are sent to partners in 30 countries across
the continent to be developed further so they can cope with local conditions.
The
Uganda bank stores around 4,000 types of beans, including some sourced from
neighboring Rwanda before its 1994 genocide killed around 800,000 people and
wiped out many of the country's bean varieties.
"The
beans have to go through certain rigorous tests before they can be released to
the general public, to make sure they do actually address all the issues well
and perform well in different climatic conditions," said Stanley Nkalubo,
a legumes research scientist with Uganda's National Agricultural Research
Organization.
The
red-striped bean that 35-year-old Opio now harvests is called NABE15, and it
has proved so popular that the U.N.'s Food and Agriculture Organization
recently contracted a large commercial producer to supply 21 tons for
distribution to South Sudanese refugees as planting materials.
Aid
workers hope the beans will encourage the refugees to grow their own food
rather than rely on handouts, which in some cases have been cut because of
funding shortages.
"It
is important that other sources of food be found to complement the food
assistance," said Beatrice Okello, senior program manager with FAO in
Uganda, saying that just 50 kilograms of planting seeds are expected to yield
of up to 2,000 kilograms of beans.
Experts
say the "super" beans are valuable because they cook quickly and
tolerate most diseases and pests. "It is also a shiny red color, which
local consumers like, and it's sweeter," said Dr. Robin Buruchara,
director of the Pan-African Bean Research Alliance.
On
a recent morning, contractor Felix Otim watched as colleagues packed planting
materials into FAO-branded bags destined for a nearby refugee camp. The beans
will save many lives, he said. Instead of using 1 kilogram (2.2 pounds) of
beans for lunch, planting it will multiply the benefit several times over.
Even
the "super" beans aren't perfect, but agricultural workers are
looking to genetic tools for future solutions.
"It's
very hard to breed any single bean variety with the very best of traits - early
maturing, drought-tolerant, pest-tolerant, high micronutrients. That would be
the super, super bean," said Debisi Araba, the African head of the Centre for Tropical Agriculture. "But that's what we are working toward. There
are genetic editing tools available now that give scientists the ability to map
out these genetic varieties and potentially we start looking at the possibility
of breeding these super, super crops."
For
now, the "super" beans are finding a following in northern Uganda.
After a neighbor noticed that Opio's plants were performing well, he bought a
sample. Now the beans are being traded across the border in turbulent South
Sudan, where famine is once again a threat.
"So even though the
target is farmer groups and organizations in Uganda, the beneficiaries are
beyond the borders of Uganda," Araba said.
