This paper analyses the supply side of food security problem using household level data in Moneragala district, Sri Lanka. The estimated household level production function shows that promoting the level of education of farming households, provision of agricultural credit facilities, converting small-scale family farms into large-scale agricultural farms, expansion of capital intensive production techniques and technological progress in food crop production are some of the major factors which increase household level food production. These are distributional issues related to the supply side of household level food security. According to the empirical estimates, the output elasticity with respect to each explanatory variable is smaller than one. This indicates that the current extensive agricultural practices are not appropriate fo r increasing food crop production in the district. Considering these research findings, policy makers should consider both efficiency and distributional issues in policy implementation for improving the food security status of farming households.
