Stimulating Private Sector Malaria Control: The Outgrower Opportunity

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.

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cotton Yields
Time Frame: 2010-2011 season (up to 1 year)
Farmer's cotton yields (kg delivered per household), as defined in the routine data collection system of the participating cotton outgrowing agribusiness
2010-2011 season (up to 1 year)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Contract Defaults
Time Frame: 2010-2011 season (up to 1 year)
Defaults on input loans, as defined in the routine data collection system of the participating cotton outgrowing agribusiness. Odds ratios calculated in accordance with NIH guidance: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938757/
2010-2011 season (up to 1 year)
Increase in Maize Productivity
Time Frame: 2009-2010 and 2010-2011 seasons (up to 2 years)
Increase in self-reported maize productivity (yield on maize plots divided by size of maize plots), collected through validation survey; calculated as maize productivity 2010-11 minus maize productivity 2009-10, measured in bags (ordinarily 50kg bags; however, kg measure not specified)
2009-2010 and 2010-2011 seasons (up to 2 years)
Self-reported Malaria Prevalence
Time Frame: 2010-2011 season (up to 1 year)
Over two weeks before interview, collected through validation survey. Odds ratio calculated in accordance with NIH guidance http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2938757/
2010-2011 season (up to 1 year)
