Parsimonious model of 2005 district-level JE incidence as a function of climate, agriculture and land-use.

p = mean precipitation, Irrigated = natural log of percentage of irrigated land per district, Pig-human = pig-to-human ratio, Grassland = natural log of percentage grassland cover per district, Rho (ρ) = spatial lag parameter.S.E. = Standard error of â coefficient.†All regression β coefficients represent a non-linear increase (or decrease when the coefficient value is negative) in JE incidence when there is a 1-unit increase in each respective predictor variable.
