Snapshot of CGIAR Impacts
Benefits of Agricultural Research
A recently published study estimating the value of the
CGIAR's activities since its inception reports a benefit-cost
ratio of 9.0 for the $7.12 billion (1990 US dollars) invested. This
ratio rises to 17.3 when extrapolated through 2011 under the
assumption that research benefits will continue to be realised at
present rates. Thus, for every dollar invested in the CGIAR, $9
worth of additional food has been produced in the developing world,
catalyzing substantial additional "multiplier effects"
for poor producers and consumers in the process.

CGIAR Impact on Prices, Production, Land use and
Trade
The following estimates of impact are derived from The
International Model for Policy Analysis of Agricultural Commodities
and Trade (IMPACT) developed by the International Food Policy
Research Institute (IFPRI). They show what would have happened to
world food production without CGIAR contributions:
- World food production would have been 4-5% lower and developing
countries
would have produced 7-8% less - exacerbating hunger, malnutrition,
and poverty
- World food and feed grain prices would have been 18-21% higher
- adversely affecting poor consumers
- Area planted to crops would have been significantly higher for
all food crops, as cultivated area in developing countries would
have expanded by 11 to 13 million hectares (and 5 to 6 million in
industrialized countries), at the expense of primary forests and
fragile lands with high biodiversity
- In developing countries, per capita food consumption would have
declined by 5% on average, and up to 7% in the poorest regions -
causing food, income, and nutrition insecurity
- Some 13-15 million more children would have been malnourished,
predominantly in South Asia, where incidence of hunger is
highest

CGIAR Contributions
New Rices for Africa (NERICAs)
NERICAs combine the high quality productivity traits of Asian rice
and the ruggedness of native Africa rice varieties. Benefits
are:
- Labor saving for women farmers.
- Higher yielding (between 25-250%).
- Increased tolerance to droughts, pests and weeds.
- It is estimated that NERICAs are planted on 100,000 hectares
and thir use is spreading across Africa. In particular, NERICAs
have been planted on 60,000 hectares in Guinea and on 10,000
hectares in Uganda.
- In Guinea alone, NERICAs have saved an estimated $13 million in
rice imports.
Quality Protein Maize (QPM)
- QPM planted on over 600,000 hectares in 25 countries, boosting
food, nutrition, health and income security
- Has twice the amount of lysine, tryptophan - essential amino
acids
- In Ghana, record yields of 7 tons per hectare achieved
Rice-Wheat Consortium of Indo-Gangetic Plains
Project promotes zero-till farming practices in rice-wheat
cropping systems
- Most intensely cropped region in the world, covers 13.5 million
ha
- Produces 45% of South Asia's food<
- Home to 42% of population (and 400 million poor people)
- Cornerstone of food, income and nutrition security
Partners
- Bangladesh, India, Nepal, Pakistan
- 5 CGIAR Centers
- Strong private sector participation (over 20,000 drills
provided by 80 companies)
- Over 10 advanced research institutions
Select impacts (wheat)
- Increased yields (10-17% over conventional tillage)
- Reduced production costs ($65-180 per hectare)
- Conserves resources (water, diesel, herbicides)
