FAO Hunger Indicators

Target 1C - Halve, between 1990 and2015, the proportion of people whosuffer from hunger

MDG Hunger indicator 1.9:

Reduce the proportion of population belowminimum level of dietary energy

requirement (MDER) by half by 2015.

World Food Summit Target :

Reduce the number of undernourished peopleby half by 2015.

The FAO approach for estimating food deprivation

Based on three key parameters:1. Energy consumption per person (DES) as derived from

- Food Balance Sheet (FBS)

2. Inequality in access to food (CV of DEC)

- National household income and expenditure survey (NHS)

3. The minimum dietary energy requirement (MDER)

- Based on International Dietary Energy Requirement Normsusing country age/sex structure of the population and heightdata.

Countrys Food BalanceSheet

Food Balance Sheets aim is calculate the totalfood availability per country and yearexpressed in their nutritive value (Kcal).

From these values and the availablepopulation estimates, the dietary energyconsumption (Kcal/person/day) is derived.

Dietary energy consumption(kcal/person/day) is the base for thecomputation of indicators of food security of a country.

Undernourishment refers to the condition of peoplewhose dietary energy consumption is continuously

Analysis of Country Agricultural and Food Data

Compilation of FBS(Improved Crop Production Estimation

Methodology; Appropriate tools for SUA and FBS)

2. Food Security Analysis of NHIES( Use of ADePT tool)

Conclusions

Countries have the agricultural and food data for a food and

nutrition analysis at national and sub-national levels

(NHIES/FBS).

Build capacity to compile FBS and reconciliation with NHIES.

Use of own production data to supplement production data

Improved estimation methods of crop production

SUA/FBS compilation toolsInstitutional contribution for the collection and analysis of

quality and consistent agricultural and food data to derive

timely food and nutrition security indicators.
