For over three decades, CGIAR has
been a strong partner in Africa’s development, providing new
crop and farming technologies that target the crucial
agricultural sector, benefiting poor farmers, creating wealth,
and protecting the environment. For example:
New Rices for Africa
(NERICAs) developed by
The Africa Rice Center provide higher yields, are drought
tolerant and thrive in salty soils. Across Africa, NERICAs are
being planted on 100,000 hectares (including 60,000 hectares in
Guinea and about 10,000 hectares in Uganda) and are helping
countries cut crippling rice import bills
New, improved,
drought-resistant maize (Zea mays L.) varieties
adapted for harsh ecologies of southern Africa are planted on
over 250,000 hectares, providing farmers with 30 percent higher
yields.
Quality protein maize,
containing twice the amount of beneficial nutrients such as
lysine and tryptophan, is boosting household nutrition in Africa
and elsewhere. QPM is currently planted in 25 countries, many of
which are in Africa (www.cimmyt.org)
CIP’s Vitamin A for
Africa (VITAA) Partnership is helping tackle one of the
most pressing health and nutrition problems in Sub-Saharan
Africa: Vitamin A deficiency (VAD). New, orange-fleshed sweet
potato varieties with enhanced beta-carotene are proving
valuable in the fight against VAD that affects some 3 million
children in Sub-Saharan Africa who are under the age of five (
www.cipotato.org/vitaa).
Sorghum,
millet, groundnut, chickpea and pigeonpea :
Close partnerships between African researchers and ICRISAT over
three decades created improved varieties ofsorghum, millet,
groundnut, chickpea and pigeonpea) being grown on a million
hectares each year. Both smallholder farmers and poor consumers
benefit from higher yields, better food quality, resistance to
diseases and pests, and earlier harvest of their crops before
the rains end, lowering drought risk. The joint research, based
in Burkina Faso, Kenya, Mali, Malawi, Kenya, Niger and Zimbabwe
helped all the countries in the Sahelian, Kalahari and East
African drylands.

Livestock
provide draft power, milk and meat. In much of Africa, livestock
are a symbol of wealth and social status. ILRI scientists
working in Ethiopia’s remote Ghibe Valley are tackling a
trypanosomosis epidemic that has felled hundreds of zebu cattle.
The benefits of this research included increases in farmers’
herd sizes (www.ilri.org).
Cassava mosaic disease
cuts cassava production in Africa by 15 to 25 percent. In late
1980s, the disease affected Uganda, Kenya, Sudan and Tanzania.
Thanks to efforts by IITA researchers and partners, new disease
resistant cassava varieties have boosted production in Uganda to
a record high of 5 million tons, up from a low of just 2 million
tons at the worst phase of the epidemic (www.iita.org).
Every year, stem borers
voraciously consume 400,000 tons of maize
causing an estimated $72 million in losses for Kenya. That sum
represents over 12 percent of the farmers’ annual harvest.
Researchers from CIMMYT, working in close cooperation with Kenya
Agricultural Research Institute are collaborating to identify
conventional and novel sources of stem borer resistance and
incorporating them into maize varieties that are well suited to
Kenyan growing conditions and to farmer and consumer preferences
(www.cimmyt.org,
www.kari.org).
Locusts are the bane of
farmers in Africa. IITA researchers and partners have
developed an environmentally-friendly biopesticide “Green
Muscle.” It uses a naturally occurring fungus strain indigenous
to Africa (Metarhizium anisopliae) which is deadly to
locusts and grasshoppers but does not damage other insects,
plants, animals, or people. Typically 70 to 100 percent
mortality rates were obtained after 8 to 28 days of application
( www.iita.org)
Researchers at
World
Agroforestry Centre are promoting agroforestry
– the planting of trees on farms – as a means
to improve fertility of nutrient-depleted soils. In Embu
District of eastern Kenya, more than 3,000 farmers are planting
tree legumes in fodder banks for use as an inexpensive protein
supplement for their dairy cows |
