Title: International Potato Center, Mozambique


1
  • International Potato Center, Mozambique
  • Annual Review Meeting. Lima, October 27
    November 7, 2008

2
  • The supply of sweetpotato planting material in
    Southern Africa faces many challenges
  • Availability of SP planting material constrained
    by limited public sectors or short run projects
    involving large NGOs with a defined free vine
    distribution
  • Although considered a public good, dry prone
    areas make it difficult to keep SP vines from one
    season to another
  • The lack of alternative seed suppliers would
    affect long term sustainability of the Seed
    System

3
  • Could private sector in Africa engage in a
    sustainable planting material production?
  • Are small farmers willing to pay for sweetpotato
    vines?
  • Is it profitable to produce sweetpotato vines
    under local farmer conditions?
  • Exploring the creation of a decentralize vine
    multipliers network in Central Mozambique

4
  • How could vine multiplication become a
    sustainable activity?
  • Are there incentives to encourage private
    planting material production?
  • Exploring the establishment of decentralize vine
    multipliers The experience of the REU in
    Mozambique

5
  • Results from a
  • Real Choice
  • Experiment (RCE)
  • In Mozambique

6
  • There is no market for sweetpotato vines
  • Most of SP vines are distributed freely
  • Little planting material sold at arbitrary fixed
    prices
  • In Mozambique vine price fixed at 0.06 US, well
    below Government/NGO production cost
  • The RCE was targeted to replicate real market
    conditions farmers faced real purchase choice

7
  • Participants received 0.24 US with no obligation
    of vine purchase
  • Participant expressed his/her varietal preference
    and willing to pay on 10 different choice
    scenarios
  • Paired SP varieties for
  • comparison (4 OFSP 1 local)
  • Each variety displayed a price
  • Prices assigned randomly
  • (fractional factorial design)

8
Choice experiment format
9
  • In each scenario respondent selects the variety
    he/she prefers and is willing to buy at displayed
    price
  • Respondents had the option of none of the two
  • But, they were aware that at the end of the
    exercise, he/she will randomly select one of the
    10 scenarios and buy the preferred variety at the
    scenario price.
  • Farmer free to choose the quantity of vines to be
    purchased (minimum 1 kg)
  • The same day farmers went home with the purchased
    OFSP variety

10
  • 120 respondents (6 communities)
  • Respondents with OFSP experience
  • but with no vine distribution recently
  • Variety information (yields,taste,pest
  • drought tolerance,vitamin A content)
  • With responses to different scenarios we
    estimated their WTP for OFSP vines using an
    econometric mixed logit model

11
  • Real choice
  • Experiment
  • Results

12
Experience and knowledge of individual OFSP
varieties among respondents N121)
13
  • Farmers evaluation of attributes of OFSP
    varieties

14
  • Quantity of vines bought and money invested by
    respondents

15
  • Frequency and percentage of selection of
    different OFSP varieties

16
  • Farmers responses to different prices in the
    experiment scenario

17
  • On average WTP
  • 0.06 US for local varieties
  • 0.08 US for OFSP vines
  • WTP across OFSP Jonathan 100
  • (Index) Resisto
    170
  • MGCL01
    171
  • LO323
    137

18
  • RCE revealed higher WTP for any OFSP variety than
    local varieties
  • The two most preferred varieties are
  • Resisto for yield and taste properties
  • MGCL01 for yield, taste and most importantly
    drought resistance
  • On average farmers invested 0.09 US in buying
    OFSP vines, but a group invested more than 0.24
    US
  • Farmers are willing to pay more for vines when
    switching to MGCL01 or Resisto

  • The REU project
  • Experience selling
  • Vines in 2008

21
  • In 2008 the REU project decided to sell vines in
    at least half of its participant communities
  • Opted for a differentiated price policy
  • 10 vines _at_ 0.04 US
  • 25 vines _at_ 0.08 US
  • 1-3 kg _at_ 0.10 US per Kg
  • 4-11 kg _at_ 0.08 US per Kg
  • 12 above Kg at 0.06 US per Kg
  • Farmers could request and pay for any quantity

Average price paid for OFSP vines 2008

Relative importance of OFSP varieties bought in
2008 by small growers
25
  • 2008 vine distribution is consistent with WTP
    results
  • Farmers paid on average more than the fixed price
    of 0.06 US
  • Either paying a higher price or investing in buy
    large quantities of OFSP vines
  • Farmers value more desired characteristics of
    OFSP varieties and bought more MGCL01 and
    Resisto
  • Areas with market orientation are willing to pay
    more for OFSP vines
  • With project support farmers willing to buy high
    quality OFSP vines could buy these vines from
    other farmers, that as demonstrated can produce
    vines commercially

26
  • Results from irrigated
  • On-farm trials
  • Multiplication rates
  • Production costs

27
  • 16 on-farm trials and 1 on-station
  • (4 replications)
  • Two levels of comparison
  • Multiplication technique
  • (Rapid vs. conventional)
  • Irrigation scheme
  • (Watering can vs. treadle pumps)
  • 3 varieties Resisto, Jonathan, MGCL01

  • At farmers conditions, conventional
    multiplication using watering can the more
    attractive scheme
  • Higher multiplication rates
  • Lowest cost per kilogram of vine produced
  • While farmers are willing to pay on average 0.07
    US per kilo of OFSP vines (up to 0.08 US), they
    can produce these vines as a low cost as 0.02
    US
  • Vine multiplication seems to be attractive to
    small farmers in Mozambique. A network of
    decentralize vine multiplier would enhance the
    sustainability of the Seed System
