2Underutilized crops
- Underutilized crops have traditionally been
used for food, fibre, fodder, oil and medicinal
plants - their potential contribution to food security,
nutrition, health, income generation, and
ecosystem services for the wellbeing of mankind
is still largely under-exploited - aim to stop and indeed, reverse the biodiversity
loss in farming systems - concerned with developing agricultural
landscapes and markets that work for smallholder
farmers and local agricultural micro-entrepreneurs
.
Ecosystem diversity
Intra-specific
Inter-specific
3- estimated 7,000 species playing a crucial role in
poor people's livelihoods and many of these have
a significant potential for commercialization - only 150 plant species have been noted for use
and commercialization on a global scale and rice,
wheat and maize dominate and together, these
provide over 50 of the world's protein and
calorie needs. - Alongside their commercial potential however,
many underutilized plant species also provide
important environmental services.
4- FARA-led Agricultural Biodiversity Initiative for
Africa (ABIA) aims to promote conservation and
sustainably USE - Challenges
- (i) weak knowledge base on the significance of
agricultural biodiversity, including its value to
society, and potential for development -
- (ii) too much emphasis on plants especially the
main staples and the neglect of others - (iii) over-emphasis on conservation for future
use at expense of USE and management for present
and future challenges - (iv) gene banks often seen as independent organ
in the maintenance of agricultural biodiversity,
with little or no link with other arms of
agricultural research and with communities - (v) policy and strategies that do not often
directly promote wellbeing.
5- efforts in agricultural biodiversity management
and USE, at both country and regional levels,
have been inadequate and largely uncoordinated,
due both to financial and policy limitations. The
inadequacies have worked against optimizing
benefits from these resources, and contributed to
the loss of valuable genetic resources in Africa.
- the only sustainable way to guarantee the success
of a biodiversity agenda, and indeed to conserve
any countrys natural resources, is to ensure
that policy actions lead to socioeconomic
transformation and improved quality of life - shift in paradigm in which conservation was
largely seen as a Government responsibility, to
one where biodiversity protection is viewed as a
profitable business opportunity for both
mainstream enterprise and small business - need to develop business models that make sound
use of available natural resources, with a view
to generate dividends for all levels of society
especially the economically vulnerable rural
communities - emerging interest on underutilized species and in
particular minor crops, demonstrate renewed
public and private attention on biodiversity and
its sustainable use of new crops for new uses,
and new markets, hence this international
conference is well placed.
6- agronomic traits, appearance, processing
qualities, taste, storability, nutritional
elements, a range of possible uses, and
environmental adaptability have all contributed
to the success of the worlds major crops - successful improvement and promotion of neglected
underutilized crops has been constrained by the
aforementioned challenges - further worsened by the limited number of orphan
crop germplasm in gene banks and the limited
number of scientists and development agents
working on these minor crops - obvious that crop diversification at all levels
and all types of agro-ecologies is the most
crucial element of sustainable ecosystem services - narrow portfolio of global agriculture therefore
raises major concerns on how effectively, major
crops alone, can contribute to food security and
poverty alleviation, improved nutrition, income,
and sustainable ecosystem services.
7FOOD SECURITY IN AFRICA CASE OF NERICA
from Asia
to Africa
8NERICAs New Rices for Africa
- significant contribution of the African rice
cultivarOryza glaberrima, an underutilized and
fading specie to societal wellbeing - 1990s WARDA researchers began to screen WARDAs
holdings of African rice cultivars, having
discovered that O. glaberrima an underutilized
specie, had a number of agronomic properties
suitable for use by farmers working in low input
conditions - influenced the decision to re-open the
possibility of hybridising the high yielding,
reduced lodging and shattering associated with
the Asian riceO. sativa with the highly stress
resilient African glaberimma. - released as NERICA (new rices for Africa) types
- NERICAs provide a welcome relief for Africas
rice farmers and provide new opportunity for
sustainable agricultural development especially
in rainfed environments where most of Africas
rice farmers earn a living
9Birth of the NERICAs Crossing African rice with
Asian rice
O. glaberrima as male parent
O. sativa as female parent
BC1F1 population (O. sativa x O. glaberrima)
BC2F3 population (O. sativa x O. glaberrima)
10African Rice - Oryza glaberrima
- Domesticated 3,500 years ago
- Hardy drought resistant
- Prone to lodging and shattering
- Low yield
11Asian rice - Oryza sativa
- High yield
- Low resistance to African pest diseases
- Low weed competitiveness
12 Creating new interspecific progenies
the anther culture process
Anther culture plants
Calli derived from anthers on induction medium
vegetative phase
Regenerating and tillering
Three ploidy levels Haploid, Diploid Polyploid
reproductive phase
Plantlets on rooting medium
13Traits of NERICAs
- From sativa parents
- Non-shattering grains
- Secondary branches giving higher yield
- Responsiveness to mineral fertilizer
- From glaberrima parents
- Weed competitiveness
- Drought tolerance
- Resistance to African gall midge, rice yellow
mottle virus, blast disease - Taste and aroma
- NERICA has higher protein content than its parents
14Achieving impact through participatory approaches
- Participatory Varietal Selection
- 3-year program involving NARS farmers
- Year 1, rice garden of promising varieties
farmers local varieties - Year 2, farmers plant their selected varieties
- Year 3, farmers expand planted area of selected
varieties
15Adding value to Participatory Varietal Selection
- PVS
- Community-based seed system Entrepreneurship
adds value to PVS - Farmers trained to become seed producers
- Quality seeds made available to large number of
farmers within 4-5 yrs - Challenge
- sustainable development of private seed
entrepreneurs
16Facing the challenges
Multi-institutional collaboration among
scientific and development communities
. The NERICA success
17Diffusion and Adoption of NERICA in Cote dIvoire
- NERICA adoption rate among the population stood
at 27 in 2000 -
- NERICA adoption rate among the population
projected to rise rapidly from the 2000 level,
reaching 68 as early as 2006. - projected long-run NERICA adoption rate of 76
(reached after 25 years)

19Impact of NERICA adoption in Benin
- Impact on rice productivity
- Impact on rice yield 914.9 kg/ha
- Impact on rice income 1959 FCFA per capita
- Impact on child schooling
- 3 increase in school attendance rate
- About 5,000 CFA increase per child in school
expenditures - Impact on child health
- 5 increase in the hospital attendance frequency
when sick - About 7,000CFA increase in health expenses per
sick child
