This paper documents the main findings of a study on food insecurity and vulnerability in the Indian state of Orissa in support of promoting interventions for food security and livelihoods at state level. The paper analyses the main characteristics and causes of food insecurity and vulnerability. It seeks to identify who are vulnerable and food insecure and where they are, why they risk food insecurity and what options exist to reduce their vulnerability. Using the sustainable livelihoods framework and collecting qualitative and quantitative data from four selected districts, the paper looks at six livelihood groups, notably marginal and small scale farming households, labouring rural households, mining worker households, rural artisan households, fishing households and scheduled tribal households.
