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.
The objectives of the CSFVA in Tanzania were to:
· provide information on food security and nutritional status in rural Tanzania;
· document the resources accessible to rural households and resources allocation, including the livelihood and income earning activities pursued at the household level;
· assess rural communities' exposure to crisis and coping mechanisms used by rural communities
· evaluate the context (education, health, social structure) and future risks for food security and livelihoods;
· establish a typology and geographic distribution of households food insecurity and vulnerability to food insecurity and assess their geographic distribution; and
· recommend appropriate food and non food programme interventions to address both contextual and structural problems that affect food security in rural Tanzania

Sampling
The household sample was taken using a two-stage random sample method. Fourteen villages were randomly selected with probability proportional to size for each Region (an additional 3 villages were selected as replacements incase the village could not be located or was not reachable within the time frame due to extreme logistical and transport constraints; total of 17 villages selected during the randomization process). Upon arrival at each village the supervisor of the team, with the assistance of the village authorities, identified the total number of vitongoje (smallest administrative area). From this list one kitongoje was randomly selected using a random number table. The purpose of selecting individual kitongoje was to reduce movement around often large expanses of the villages. The assumption is that the villages are relatively homogenous with each kitongoje being representative of the village as a whole.
Once the kitongoje was selected a complete list of households was made with the assistance of the local leaders. From this list 9households were randomly selected using a simple random selection (3 additional households were selected in the event that households selected were not available for survey). The head of the household (at least 15 years or older) was interviewed during the survey. Where a selected household or individual were absent or declined interview this was recorded and one of the additional randomly selected household were interviewed.
The minimum sample size for the whole survey was 2,772 households. Within each region data was collected from a minimum of 126 households (14 villages x 9 households). The WFP zones that were identified using the PCA had differing numbers of households depending on the size of the zone.
Household weights are calculated by population per region
Survey instrument
01 - Household Questionnaire - This questionnaire was the focus of the primary data collection and was designed to provide quantitative data in the following nine areas of interest; 1) Demographics, 2) Housing & Facilities, 3) Household Assets & Productive Assets, 4) Inputs to Livelihood, 5) Expenditure, 6) Food Sources & Consumption, 7) Shocks & Food Security, 8) Maternal Health & Nutrition and 9) Child Health & Nutrition. This tool was a structured questionnaire using tested response options for the enumerators to record the most likely and common responses to the questions. An “other - specify” option was used to capture less likely/uncommon responses. Response options were not read to the respondent. For several questions respondents were allowed to provide more than one response.
02 - Community Questionnaire - This questionnaire was both qualitative and quantitative and designed to provide information that is common to the majority of the sampled village population. This was in order to reduce the duration of the household interview. Qualitative questions helped to provide context to the data provided from the household questionnaires. This questionnaire contained 7 sections; 1) Demographic Information, 2) Transportation, 3) Education, 4) Health, 5) Market Information, 6) Assistance & Food Aid and 7) Agriculture.

The CFSVA was conducted by the Tanzania National Bureau of Statistics, as sub-contracted by WFP. The 22 teams of 4 people were used to conduct surveys in 22 survey zones, as described in the next section. Each team consisted of 1Team Supervisor; 1Community Interviewer; 2 Households Interviewer. The team supervisors had previous experience in conducting food security type surveys and the enumerators also had prior experience in conducting food security surveys. At least one of the team members had previous experience in taking anthropometric measurements.
Due to the large scale of the Tanzanian CFSVA (22 surveys including 88 enumerators) and time constraints, training for the data collection teams was conducted in two stages. A central training was provided for all the supervisors and facilitated by the WFP CFSVA consultant to ensure that complete and comprehensive training was provided. The enumeration teams were trained at different locations, in small groups to facilitate improved learning, by the supervisors with assistance from senior NBS staff and attended in certain locations by WFP staff.

Data processing
Statistical analysis was conducted by WFP in Tanzania and Rome. SPSS 12.0 and ADDATI 5.2c were used to conduct PCA and clustering analysis. Nutritional indicators were calculated using EpiInfo v6.04d EPINUT. All other analysis was done using SPSS 11.5 & 12.0.
