BackgroundAquaculture in Sri Lanka is

considered an important livelihood that supports income diversification

Why shrimp farming?Opening of the Eastern and

Northern Provinces Is there a possibility of income

generation for people who have re-settled after the war?

Objectives What is the food security status of shrimp

farming households?How should we measure food security?

What is food security?Food security is defined as

“a situation that exists when all people, at all times, have physical, social and economic access to sufficient, safe and nutritious food that meets their dietary needs and food preferences for an active and healthy life” (World Food Summit, 1996)

Pillars of Food Security

(FAO 2008 An Introduction to the Basic Concepts of Food Security)

Page 10: Jessica Wu, S.  Checkley , R. Silva*, T.  Westers , C.  Ribble , T. Fung, S. Daniel, & C. Stephen

Methods Cross-sectional study of 225 shrimp farming households in

Sri Lanka Structured surveys included the Household Food

Insecurity Access Scale (HFIAS) (Coates et al. 2007)

9 yes/no questions followed by timeframe question if answered affirmatively

Forward translation into Sinhala and Tamil Back translation into English followed by revisions if

required

MethodsValidation of the HFIAS

Cultural acceptability through expert panel consultationFood security experts from both countriesAcademic experts familiar with the target populationGovernment worker familiar with target population

FeasibilityPilot study

Construct validity Factor analysis of dichotomous outcomes

Internal reliabilityCronbach’s alpha

Accuracy in relating to other food security measures (correlation to socioeconomic status)

Page 12: Jessica Wu, S.  Checkley , R. Silva*, T.  Westers , C.  Ribble , T. Fung, S. Daniel, & C. Stephen

Results The HFIAS showed high cultural

acceptability Has been used in unpublished studies in

Sri Lanka Feasibility indicated no logistic or

comprehension challenges Factor analysis

One factor extracted with factor loadings 0.94 or greater

Cronbach's alpha was high (0.934) Association between food insecurity

scores and socioeconomic status was significant (p = 0.032)

Page 13: Jessica Wu, S.  Checkley , R. Silva*, T.  Westers , C.  Ribble , T. Fung, S. Daniel, & C. Stephen

ResultsThe majority of shrimp farming households in Sri

Lanka are food secure

ChallengesTranslation

Two languages = twice the number of translators

Not all translators can type in Sinhala and Tamil

Part of a larger surveyOnly one construct

derived from factor analysisSmall sample size

Page 16: Jessica Wu, S.  Checkley , R. Silva*, T.  Westers , C.  Ribble , T. Fung, S. Daniel, & C. Stephen

ConclusionsThe HFIAS, adapted to the Sri Lankan context, is

promising as a valid measure of the access pillar of food security in this country

The majority of shrimp farming households are food secure

First documented use of the HFIAS in the aquaculture sector in Sri Lanka and can be a useful tool for future food security assessments in this country
