Title: Diapositive 1


1
Estimating Local Values of Vegetable Non-Timber
Forest Products to Pendjari Biosphere Reserve
Dwellers in Benin 
VODOUHE G. Fifanou, PhD Candidate
Accra, Ghana, 15-17 October 2008
2
Context of the study
Conservation and sustainable resource use will
not be successful without the full participation
of indigenous people and the application of their
ethnobotanical and ecological knowledge
(Gemedo-Dalle et al., 2005)
3
Context of the study
That's absolutely true in Africa where people
depend on natural resources for their livelihood
for centuries (Gemedo-Dalle et al., 2005 Törn et
al., 2008)
4
Context of the study
For many authors, the non consideration of this
reality is the reason of the failures of many
efforts undertaken to conserve biodiversity in
developing countries
(Gopalakrishnan et al., 2005 Gemedo-Dalle et
al., 2005 Törn et al., 2008)
5
Need for information
This integration of people need in conservation
program cant be done without good understanding
of links between useful plants and local people
6
Study area
  • North West of Rep of Benin (1030 to 1130 N
    050 to 200 E)
  • Area 281,359ha
  • Pop 30,000 inhabitants
  • NPP was upgraded Biosphere Reserve in 1986

7
Objective
This study aimed at felling this gap of
information and will permit better understanding
of the use-values of plants for people living
around the PBR and the socio-economic and
contextual factors that may influence these
values.
8
Methods
  • Data were collected from individual using
    questionnaires
  • 186 respondents (105 men and 80 women) make up
    the research sample
  • Respondents were asked to rank by importance the
    10 most important species that they had harvested
    over the last 5 years
  • Data were analyzed using the Linear Mixed Model
    and descriptive statistics

9
Effect of use on species values
Value of species used per category of use
  • Values assigned to species by respondents vary
    according to the type of use

10
Effect of socio-economic factors on species values
Linear mixed model analysis of variance summary
Importance accorded to species was significantly
affected by factors such as type of species,
gender/species and the socio-cultural
group/species of the respondent
11
Most valued species in PBR
  • Most valued botanic families are Bombacaceae,
    Mimosaceae and Sapotaceae
  • PBR people value trees more than herbaceous
    species (Student t test, d.f. 67, P0.001)

12
Gender effect on species values
  • We consider gender at the level of relation
    between men and women because its the more
    striking gender aspect in the study area
  • Women valued species used for food more than men
    whose interest relates to species used as
    construction material and medicine

13
Socio-cultural groups and species values
Linear Mixed Model, F4.33 Plt0.001
  • People from historically hunters groups valued
    more useful species than any other
    socio-cultural groups
  • Land availability is the 2nd reason which
    explain the difference in values accorded to
    species by socio-cultural groups

14
Determinism of values assigned to species by PBR
surrounding people
  • Variation in values attributed to species could
    be explained by the transmission of
    ethnobotanical knowledge in the PBR communities
  • PBR people acquired, learned and

    taught species use by doing
  • The species knowledge is transmitted vertically
    through family dissemination

15
Conclusions
  • Although PBR people have access to a wide range
    of species, results found that only a few species
    are highly valued.
  • NTFPs are used in a wide range of categories,
    which indicates the close links between
    livelihoods and natural resources in the area.
  • Women have at least as much diversity of
    knowledge as men and show that they are also
    important stakeholders and merit consideration in
    reserve biodiversity conservation management.
  • Biodiversity conservation strategies will
    successfully teach to people using learning by
    doing strategy and focused on the most important
    species used in the area.
