Preliminary evidence from ongoing research provides strong indications that protecting farmers from malaria would be profitable for outgrowing agribusinesses in sub-Saharan Africa. The study team invests in experimental research to investigate this conjecture in more detail.

Primary Outcome Measures:
  • Cotton yields [ Time Frame: 2010-2011 season (up to 1 year) ] [ Designated as safety issue: No ]
    Farmer's cotton yields, as defined in the routine data collection system of the participating cotton outgrowing agribusiness

Secondary Outcome Measures:
  • Contract defaults [ Time Frame: 2010-2011 season (up to 1 year) ] [ Designated as safety issue: No ]
    Defaults on input loans, as defined in the routine data collection system of the participating cotton outgrowing agribusiness

  • Increase in maize productivity [ Time Frame: 2009-2010 and 2010-2011 seasons (up to 2 years) ] [ Designated as safety issue: No ]
    Increase in self-reported maize productivity (yield on maize plots divided by size of maize plots), collected through validation survey

  • Self-reported malaria incidence [ Time Frame: 2010-2011 season (up to 1 year) ] [ Designated as safety issue: No ]
    Over two weeks before interview, collected through validation survey

Arms Assigned Interventions
Experimental: Treatment: Insecticide-treated net
Smallholder farmers in the treatment group are informed that they won a raffle, and receive a free insecticide-treated net
Device: Insecticide-treated net (BASF Incerceptor)
One per farmer, once during the 2010-2011 season
No Intervention: Control
Smallholder farmers in the control group are informed that they had a chance to win an insecticide-treated mosquito net in a raffle, but did not end up winning

Detailed Description:

The study evaluates whether the sourcing of insecticide-treated nets and their distribution to smallholder farmers for free would be a profitable investment for a cotton outgrowing agribusiness in Zambia.

The study therefore carries out a major net distribution through the existing distribution channels of a cotton outgrowing agribusiness, evaluates the impact of this distribution on smallholder cotton yields, and values the profitability implications for the outgrowing agribusiness.
