IntroductionCountry brief
  • Area 322 462 km² Capital city Yamoussoukro
  • Population 20,8 millions inhabitants
  • per capita GDP F CFA 503 700 (US 1800)
  • GDP growth rate in 2008 2,3
  • Inflation rate in 2008 6,3 (Source UEMOA
    April 2009)

IntroductionImportance of rice in Côte dIvoire
  • Domestic production in 2007 700 000 tons of
    milled rice
  • Domestic consumption in 2007 1.5 million of
    milled rice
  • Almost half of domestic needs are imported

6
Introduction The national agricultural research
system
  • CNRA is the sole national agricultural research
    institution.
  • It was established by decree as semi-autonomous
    private company with minority public shareholding
    in 1998.
  • CNRA is responsible for the bulk of technological
    research related to agricultural sector food
    crops (rice, maize, ) perennial crops (cocoa,
    coffee, ) livestock and fishery

7
MethodologySampling
  • Random sampling
  • Sample size 250 households (seed and rice
    surplus type marketing)
  • Sub sample size
  • Field area measuring 62 farms (including 313
    individual rice plots)
  • Yield measuring 62 farms with three replications
    by farm
  • Socioeconomic survey 170 households

Conclusion
  • Advantages of GPS use
  • Easy to use
  • Good precision
  • Socioeconomic difficulties
  • Land pressure characterized by small rice field
    size
  • Women can not inherit land
  • Technical performance of rice cropping system
  • Low input system
  • Low yield that leads to low paddy production

26
Conclusion
  • Seed production activities
  • Market opportunities for women
  • Seed market increases women income
  • Narrow seed market
  • Some recommendations
  • Help women access to production inputs
    (equipments, fertilizers, herbicides, )
  • Emphasize participatory diffusion systems of
    improved varieties in rural area
