Inclusion Criteria:

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

Sites / Locations

National Malaria Control Centre

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

Treatment: Insecticide-treated net

Control

Arm Description

Smallholder farmers in the treatment group are informed that they won a raffle, and receive a free insecticide-treated net

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

Outcomes

Primary Outcome Measures

Cotton Yields

Farmer's cotton yields (kg delivered per household), as defined in the routine data collection system of the participating cotton outgrowing agribusiness

Secondary Outcome Measures

Contract Defaults

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/

Increase in Maize Productivity

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)

Self-reported Malaria Prevalence

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/

5. Study Description

Brief Summary

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.
