Stimulating Private Sector Malaria Control

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.

About this study

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.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Farmers who contracted with the participating cotton outgrowing company in the 2010-2011 season

Treatment and study plan

Insecticide-treated net (BASF Incerceptor)

Device

One per farmer, once during the 2010-2011 season

Primary outcomes

  1. 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

Secondary outcomes

  1. 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/

  2. 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)

  3. 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/
