Comprehensive Food Security & Vulnerability Analysis [hh/cfsva]
The CFSVA process generates a document that describes the food security status of various segments of a population over various parts of a country or region, analyses the underlying causes of vulnerability, and recommends appropriate interventions to deal with the problems. CFSVAs are undertaken in all crisis-prone food-insecure countries. The shelf life of CFSVAs is determined by the indicators being collected and reported. In most situations, CFSVA findings are valid for three to five years, unless there are drastic food security changes in the meantime.
Efforts to improve Madagascar’s food security and nutrition over the last two years have been thwarted by political instability which has disrupted data collection. With up-to-date critical information needed to contribute to evidence based decision making, UNICEF and WFP agreed to carry out a joint Comprehensive Food and Nutrition Security and Vulnerability Analysis (CFSVA+N) in 2010. The survey’s primary objectives are to:
• Provide an accurate and detailed assessment of the current food and nutrition security situation
• Assess the causes and risk factors for food and nutrition insecurity
• Identify potential ways to mitigate food and nutrition insecurity
• Reveal pockets of vulnerability where special assistance may be required.
Sample survey data [ssd]

Version

Scope
Household: Demographics, housing and facilities, assets, expenditure, migration, land and agricultural production, livestock ownership, food sources and consumption, food assistance, shocks and food security, coping mechanisms, HIV Aids, maternal and children health and nutrition.
Coverage
Rural areas of Madagascar
The survey covered household heads and women of reproductive age (15-49 years) in each sampled household. Household is defined as one (or more) people living under the same roof or different roofs, but sharing the main meals and respecting the authority of the same person (the head of the household).

Sampling
In order to have a representative sample by region and livelihood zone, a two-stage cluster sampling was applied.
First stage, the number of clusters per region was calculated based on the required sample size to determine malnutrition and food security by region (details on sample size calculation are reported below). A minimum of 25 clusters per region was set. Since the Fokontany is the smallest administrative unit with population data available, this was established as the administrative unit from which clusters were selected. A list of all Fokontany and their estimated population was obtained from INSTAT.Urban communities as defined by the latest DHS-IV were not included in the sampling frame. Using this list and the livelihood zones, 176 segments were defined corresponding to both the regions and the livelihood zones. The number of clusters in each of the 176 segments was determined based on the population per segment weighted from the total regional population. For each segment, the Fokontany and their population were introduced into ENA and the required number of cluster per segment was selected using "probability proportional to population size" (PPS) sampling technique. This process was repeated for each of the 176 segments. In total, 606 clusters were selected across the 22 regions and distributed in the 8 Livelihood zones.
Second stage: the secondary sample unit was the household as defined by INSTAT. Within the selected clusters, households were selected from an exhaustive of households using systematic random sampling.
For the anthropometric data, the households' number (as defined by the sample size calculation) was selected using a calculated interval sampling (i.e. from a Fokontany with 200 households, 20 households were selected using a sample interval of 10). The households for the food security survey were sampled from the larger list of households already selected for the anthropometric survey. This was done using an independently calculated interval sampling (i.e. from the 20 households selected for anthropometric data, 5 households were selected for food security and health data using a sample interval of 4).
Thirty-three clusters out of the 606 selected were not visited due to bad weather or insecurity.
Household weights are calculated by population per region.
Survey instrument
Household questionnaires, community questionnaires and nutrition questionnaires (which included anthropometric measurements) were used to collect the data.
