Appendix II: <strong>Food</strong> <strong>Security</strong> Index (FSI) – A Methodological Note<br />

Appendix II: <strong>Food</strong> <strong>Security</strong> Index (FSI) – A Methodological Note<br />

At the outset we must state that the <strong>Food</strong> <strong>Security</strong> Index is calculated for rural areas only. All variables<br />

constructed in this section are for rural areas, unless otherwise specified.<br />

Here we have attempted to construct a <strong>Food</strong> <strong>Security</strong> Index (FSI) at the sub-state level, that is, the<br />

district level. The district having a higher index value is considered as relatively more food secure as<br />

compared to a district with a lower index value.<br />

Broadly, we have adopted Range Equalization Method (REM) approach, adopted by UNDP (HDR<br />

2005); and Principal Component Analysis (PCA). One <strong>of</strong> the objectives <strong>of</strong> the district FSI is to show<br />

the district’s position in various dimensions <strong>of</strong> food security.<br />

The FSI is a composite index covering three dimensions, i.e. Availability factors, <strong>Access</strong> factors, and<br />

Absorption factors. Besides these three groups <strong>of</strong> factors, an additional component i.e. public<br />

entitlement has been used to explain how this influences food security. But the public entitlement<br />

factor is not included in the indices <strong>of</strong> food security. The public entitlement policy is based on various<br />

parameters which are supposed to be directly linked with food insecurity; the lower the level <strong>of</strong> food<br />

security, the greater should be public intervention. In such a scenario, the direction <strong>of</strong> public<br />

interventions should run counter to the FSI, though it need not be so.<br />

Table A 2.1: Choice <strong>of</strong> Indicators, Sources, Reference Year<br />

and Calculating Procedure in <strong>Bihar</strong><br />

Name <strong>of</strong> Variable and Description Sources Ref. year<br />

(a) Availability<br />

1. Proportion <strong>of</strong> net irrigated area to net sown area Department <strong>of</strong> Planning, 1998-99<br />

Government <strong>of</strong> <strong>Bihar</strong><br />

2. Per capita value <strong>of</strong> agricultural output. In order to take Department <strong>of</strong> Planning, 1997-98 to<br />

account <strong>of</strong> the cyclical nature <strong>of</strong> agricultural production the Government <strong>of</strong> <strong>Bihar</strong> 1999-2000<br />

variable uses an average <strong>of</strong> three to five years depending downloaded from<br />

on the availability <strong>of</strong> data. The value <strong>of</strong> each food and non- http://planning.bih.nic.in/<br />

food item is derived by multiplying the amount <strong>of</strong><br />

production with its price obtained from all-India prices <strong>of</strong><br />

these items at constant 1993-94 prices. Adding the value <strong>of</strong><br />

each and every food and non-food item, gives the overall<br />

value <strong>of</strong> agricultural output for a year. The per capita value<br />

<strong>of</strong> agricultural output is calculated by dividing the average<br />

value <strong>of</strong> agricultural output by total population in the<br />

midpoint year.<br />

3. Percentage <strong>of</strong> inhabited villages having access to paved Census <strong>of</strong> India, 2001 2001<br />

roads. This is calculated as a share <strong>of</strong> total number <strong>of</strong><br />

villages in the district.<br />

(b) <strong>Access</strong><br />

1. Percentage <strong>of</strong> agricultural labour to total workers.<br />

Agricultural labour comprises both main and<br />

marginal workers* Census <strong>of</strong> India, 2001 2001<br />
