We exploit a spatial discontinuity in the coverage of an agricultural extension program
in Uganda to causally identify its effects on malaria. We find that eligibility for the program
reduced the incidence of malaria by 8.8 percentage points, with children and pregnant women
experiencing most of these improvements. An examination of the underlying mechanisms
indicates that an increase in income and the resulting increase in the ownership and usage of
bednets is the most likely candidate driving these effects. Taken together, these results signify the
importance of liquidity constraints in investments for malaria prevention and the potential role
that agricultural development can play in easing it.
