Assessment of Spatio-Temporal Dynamics of Food Security Based on Food Security Index Analysis: A Case from Vaishali District, India

Abstract: The paper has generated Food Security Index as a composite index of its three component indexes and analyzed spatio-temporal variation in food security at block level in Vaishali district of a backward state in India during 2000-03 and 2007-10. FSI identified not only the blocks requiring immediate attention but also the specific priority areas in which the efforts could be focused to attain long term sustainability of food security. The composite FSI using time series data could help in identifying the priority components and analyzing the progress of development interventions over a period of time aimed at sustainable food security.
