Measuring disaggregate level food insecurity via multivariate small area modelling: evidence from rural districts of Uttar Pradesh, India

Abstract

In recent times, India has achieved significant advancement on several health indicators while the state of food security in the country still needs sustained efforts to accelerate attainment. Existing data based on socio-economic surveys conducted by National Sample Survey Office (NSSO) produce precise measures of food security status at state and national level. However, these NSSO surveys cannot be used directly to produce reliable district or further smaller domain level estimates because of small sample sizes which lead to high level of sampling variability. As food security is often unevenly distributed among the subsets of relatively small areas, the availability of disaggregate (e.g. district) level statistics for target oriented effective policy planning and monitoring is the need of the hour for decentralized administrative planning system in India. But, due to lack of district level estimates, the mapping and analysis related to food and nutrition security measures are restricted to state and national level. As a result, disaggregate level dissimilarity and variability existing in food and nutrition security are often masked. This article delineates multivariate small area estimation (SAE) technique to obtain reliable and representative model-based estimates of food insecurity indicators at district level for the rural areas of state of Uttar Pradesh in India by combining latest round of available Household Consumer Expenditure Survey 2011–12 data of NSSO and the Indian Population Census 2011. The empirical evidence indicate that the estimates generated by SAE approach are reliable and representative. Spatial maps showing district level inequality in distribution of food insecurity in Uttar Pradesh is also produced. The disaggregate level estimates and spatial maps of food insecurity are directly relevant to sustainable development goal indicator 2.1.2 - severity of food insecurity. The estimates and maps of food insecurity indictors are anticipated to offer irreplaceable information to administrative decision-makers and policy experts for identifying the regions requiring more attention. Government of India has recently launched number of schemes for the benefit of rural population in the country and these estimates will be useful for fund allocation as well as in the monitoring of these schemes.
