Women's role in food security may have earned acknowledgement, but there is no measure of how much and in what ways women actually contribute to household food security. The absence of a suitable methodology of assessment means that not only does their contribution remain vague but there is also a lack of solid data to draw policy inferences in terms of operationalisation of food security and women's empowerment. This article, based on research conducted in two villages in Nanded, Maharashtra, seeks to quantify women's contribution to household food security. Through investigation into the time-use pattern of women's activities, it also arrives at a method to estimate how much women contribute to security with their visible and invisible work.
