Stimulating Private Sector Malaria Control

Not Applicable

Completed

• Conditions: Malaria
• Interventions: Device: Insecticide-treated net (BASF Incerceptor)

• Registration Number: NCT01397851
• Lead Sponsor: PATH

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.

Arm && Interventions

Group	Intervention	Description
Treatment: Insecticide-treated net	Insecticide-treated net (BASF Incerceptor)	Smallholder farmers in the treatment group are informed that they won a raffle, and receive a free insecticide-treated net

Primary Outcome Measures

Name	Time	Method
Cotton Yields	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 Outcome Measures

Name	Time	Method
Contract Defaults	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/
Increase in Maize Productivity	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)
Self-reported Malaria Prevalence	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/
