Underutilized 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
    .

  • 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.

  • 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.

  • 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.

  • 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.

FOOD SECURITY IN AFRICA CASE OF NERICA
from Asia
to Africa
8
NERICAs 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

Birth 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)
10
African Rice - Oryza glaberrima
  • Domesticated 3,500 years ago
  • Hardy drought resistant
  • Prone to lodging and shattering
  • Low yield

11
Asian 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
13
Traits 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

14
Achieving 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

15
Adding 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

16
Facing the challenges
Multi-institutional collaboration among
scientific and development communities
. The NERICA success

Diffusion 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)

Impact 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
