Title: Impact of salinity on Shrimp-prawn farming, household food consumption and nutritional outcomes of adolescent girls at different agro-ecological landscape in Bangladesh
Mamun has his expertise in aquaculture system and its impact on food & nutritional security on seafood farming communities. Shrimp-prawn farming across the agro-ecologies in Bangladesh has given a new insights of the system and indicated that it is a family driven small scale polyculture system where cash crops provided higher economic return and other co-products supplies a substantial amount food fish in the domestic markets of Bangladesh. Omega-3 index of unmarried adolescent girls were in intermediate (Harris 2007) stage in higher saline areas while undesirable in lower saline areas agro-ecologies. The intra-household food allocation disparity still exist across the agro-ecologies and social well-being where the adolescent got the minimum share of food. A metric is being developed to understand the impact of aquaculture intervention on health outcomes based on these research works.
Aquaculture is well established for ensuring food security, economic development, improved nutrition and poverty alleviation. But the shrimp and prawn farming issues due to socio-economic and environmental degradation require further consideration. However very little effort has been given to provide a holistic scenario of shrimp-prawn farming and its direct and indirect impacts on food and nutrition security in LIDCs including Bangladesh. This multi-disciplinary work was aimed at identifying the existing farming systems at different agro-ecological landscapes in the south-west coastal seafood farming area in Bangladesh and its impact on community food security.
Methodology & Theoretical Orientation:
On the basis of surface water salinity level, the shrimp-prawn farming areas were divided into four different agro-ecological zones: (high saline (HS)>10ppt, medium saline (MS)<10>5, low saline (LS)<5ppt; freshwater (FW) area 0ppt). In depth survey both in farm and household level were executed. Social well-being categories (better-off and worse-off) were practiced according to Haque (2007). The criterion for selection of households was having at least one unmarried adolescent girl (10-18 years old). 24hrs foods recall method and food frequency questionnaire were developed and administrated with two replications and the anthropometric data height, weight, age, sex, MUAC were collected to address the preparedness for critical 1000 days issues. Blood samples from finger tips were collected and dried on a sample pad to identify the n-3 fatty acid level being one of the vital biomarkers to address the adolescent health outcomes that are mostly related to seafood consumption.
