The incidence and depth of food and nutritional insecurity has been estimated and its determinants in a food-surplus area, viz. the state of Punjab, have been studied. The consumption expenditure has been found to be directly associated with the levels of income/assets in both rural and urban areas. The study has revealed that the food and nutritional insecurity prevails even in the food-surplus areas, with low-income households being more vulnerable to it. The access to food determined by the level of income and family-size has been found as the most important factor influencing food and nutritional security in food-surplus areas. Increase in production alone does not ensure food and nutritional security. The study has suggested that income and employment opportunities for more vulnerable sections of the society will have to be augmented to alleviate their food insecurity and malnutrition.
