DEFINING FOOD SECURITY
& VULNERABILITY

Food security and vulnerability? There is a direct link between the definition of these terms and the methods that should be used to measure and assess them in the field.


The Standard Analytical Framework (SAF), and therefore VAM assessments, are built on specific and commonly accepted definitions of two key terms: food security and vulnerability.

FOOD SECURITY


Food security exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food, which meets their dietary needs and food preferences for an active and healthy life
World Food Summit 1996  
Like health or social welfare, there is no single, direct measure of food security. The food security status of any one area, community, household or individual, over a defined period of time, is determined by the interaction of a wide range of factors: agro-environmental, socio-economic, political and cultural as well as biological.


Such complexity is simplified for assessment purposes by focusing on several distinct, but inter-related, functional dimensions of food security:

  • Aggregate food availability in a specified area: Are the food stocks already in, or brought to, the area from all sources - local and national production, international imports -- and distributed by whatever method - markets, food aid, gifts -- sufficient to meet human consumption requirements in that area?

  • Household food access: do the amount and timing of a household's income, food production and entitlements give all its members the means to acquire enough food to meet consumption requirements?

  • Food utilisation: will the quantity, type, and quality of food consumed be sufficient to maintain an active and healthy life?

VULNERABILITY TO FOOD INSECURITY


Vulnerability
(to food insecurity)
= exposure to risk, mitigated by the ability to cope
Vulnerability can be defined as the probability of an acute decline in "food access" or "consumption".
It can be measured as a function of two factors:
  • Exposure to risk: a factor of the frequency, probability of occurrence, and severity of impact of natural / man-made hazards.

  • Ability to cope: determined by the existing level of food security and the ability of vulnerable groups to offset income and food production losses caused by natural / man-made hazards

ANALYSIS OF
FOOD SECURITY / VULNERABILITY

Food security analysis takes a "snapshot" of how much food availability, access and utilization a group has, and compares it with the amount the group needs to be secure for a specified period of time.

Vulnerability analysis is a forward-looking analysis that considers how food secure (or insecure) a group is, and then assesses the likelihood that "shocks" (drought, floods, etc.) could make them insecure in the future.

It also gauges whether they can effectively mitigate the impact of the shocks and re-establish their food security once it is lost.

THE FOOD INSECURE AND VULNERABLE

There is always a significant overlap between families currently food insecure and those that risk becoming food insecure in the future.

From a WFP operational perspective, the priority of both food security and vulnerability analysis should be pinpointing households that are already or close to being food insecure.

But WFP vulnerability analysis also pays particular attention to the conditions of the following groups:

  • Young children, and pregnant and lactating women, because of their special developmental and dietary needs

  • Female-headed households (see below), the elderly, the sick and the disabled.

Gender-sensitive Vulnerability Analysis

WFP has made a special commitment to women, and views food aid as an important means to ensure women gain access to social and economic resources

Understanding the gender aspects of food insecurity and vulnerability - for example what stops women from developing sustainable coping mechanisms or gaining access to a key assets such as finance, food or livestock - is a key dimension of all SAF assessments

Gender-sensitive vulnerability analysis is an important means for WFP to better understand the particular problems women face in developing countries and to identify opportunities where food aid can be used to redress the situation
