The paper contributes to an understanding of the determinants of food security with a bias on the link between gender of household head and food security using detailed farm household and plot level survey data from 30 divisions in rural Kenya. Both parametric and non-parametric econometric techniques are used to ensure robustness of the results from the econometric analyses. Since the assumption of pooled regression is rejected, we run separate food security regressions at plot level both for Male Headed Households (MHHs) and Female Headed Households (FHHs).
