Future scenarios of fish supply and demand for food and nutrition security in Bangladesh: An analysis with the AsiaFish model

Bangladesh has made significant progress in social and economic development in recent years, but micronutrient deficiencies and poor dietary diversity remain a significant challenge. This paper developed eight scenarios to explore fish supply-demand futures in Bangladesh using the AsiaFish model, with special emphasis on the role of fish in micronutrient supply to address the nation’s malnutrition and nutrition security challenges. A business-as-usual (BAU) scenario followed historical trends for exogenous variables used in the model. The seven alternative scenarios explored were: the implications of increase productivity of farmed tilapia, pangasius and rohu carp (AS1); productivity changes in hilsa production (AS2); improvements in the quality of feeds (AS3); reduction in the price of plant-based feeds (AS4); disease outbreak in farmed shrimps and prawns (AS5); and climate change impact (AS6) and stagnant capture fisheries (AS7). The BAU scenario indicates that aquaculture growth will be a prominent contribution to increasing total fish supply and demand and fish exports to 2040. Apart from the scenarios that are favourable to aquaculture sector development, other alternative scenarios highlighted the lower growth rate of capture fisheries and aquaculture compared to BAU, resulting in declining in per capita fish consumption, fish exports and nutrient supply from fish as a consequence. Increased availability of aquaculture fish can slightly compensate for the lower growth of capture fisheries in term of their nutrition quality and dietary diversity, particularly for poor consumers. Policies towards sustaining fisheries and a nutrition-sensitive approach to aquaculture is recommended as both capture fisheries and aquaculture are essential for sustaining healthy and nutritious diets in Bangladesh.

Orange fleshed sweet potato a nutrition sensitive functional food for possible dietary approach to vitamin A deficiency and undernutrition

Orange Fleshed Sweet Potatoes (OFSPs) is an excellent nutrition sensitive function food. It contains dense amount of carotene and is also rich in proximate nutrients. A wide number of cultivars of OFSPs has been developed worldwide, particularly in sub-Saharan Africa and Asia. In Bangladesh, sixteen cultivars have been developed. Carotene content in the OFSPs surpasses all of the plant food carotene. OFSPs also contains good content of energy yielding nutrients. The Orange Fleshed Sweet Potatoes could, therefore, be a potential dietary approach to address the vitamin A deficiency for undernourished indigent people.

A short note on the BMI and on secular changes in BMI

Human size changes over time with worldwide secular trends in height, weight, and body mass index (BMI). There is general agreement to relate the state of nutrition to height and weight, and to ratios of weight-to-height. The BMI is a ratio. It is commonly used to classify underweight, overweight and obesity in adults. Yet, the BMI is inappropriate to provide any immediate information on body composition. It is accepted that the BMI is “a simple index to classify underweight, overweight and obesity in adults”. It is stated that “policies, programmes and investments need to be “nutrition-sensitive”, which means they must have positive impacts on nutrition”. It is also stated that “a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions“. But these statements are neither warranted by arithmetic considerations, nor by historic evidence. Measuring the BMI is an appropriate screening tool for detecting an unusual weight-to-height ratio, but the BMI is an inappropriate tool for estimating body composition, or suggesting medical and health policy decisions.

Okra (Abelmoschus esculentus) in a refugee context in East Africa: Kitchen gardening helps with mineral provision

Kitchen gardening is considered a way to reconnect with agriculture and complement the cereal-based relief food offered to refugees in East Africa. This work aimed at profiling mineral content of okra in four refugee camps and settlements located in Ethiopia and Uganda and its contribution to adequate intake (AIs) or recommended dietary allowances (RDAs) for young children and pregnant and lactating women (PLW). The study also evaluated the applicability of portable X-ray fluorescence (PXRF) as compared with inductively coupled plasma mass spectrometry (ICP-MS) for mineral profiling of okra powder samples. The contents of minerals (mg kg−1) from the ICP-MS readings were in the following ranges: K (14,385–33,294), Ca (2610–14,090), P (3178–13,248), Mg (3896–7986), Cu (3.81–19.3), Fe (75.7–1243), Zn (33–141) and Mn (23.1–261). Regardless of geographic origin, at low-end consumption probability (17 g day−1 for young children and 68 g day−1 for PLW), okra could contribute ˂ 15% (2.7–12.9%) AI for macro-minerals (K and Ca). In addition, the contributions to RDA values for Fe and Zn, elements of known public health interest, ranged from 4.5 to 34.7% for young children. Interestingly, regression lines revealed strong agreement between ICP-MS and PXRF readings for Mn and Zn, with R2 values > 0.91. This information is useful in support of nutrition-sensitive kitchen gardening programs through scaling culturally important crops in refugee settings.

Prevalence, Trends, and Socioeconomic Determinants of Coexisting Forms of Malnutrition Amongst Children under Five Years of Age in Pakistan

In Pakistan, malnutrition is a chronic issue. Concerns regarding coexisting forms of malnutrition (CFM) in an individual child are emerging, as children suffering from CFM have a 4 to 12-fold higher risk of death compared with healthy children. This study assessed the prevalence, trends, and socioeconomic determinants of various types of CFM using Pakistan Demographic and Health Survey (PDHS) datasets. Data from children aged 0–5 years old, with complete height and weight information, and valid anthropometry, from all regions of Pakistan (except residents of Azad Jammu Kashmir (AJK) and Federally Administered Tribal Areas (FATA), and non-de jure residents), were included. The prevalence of CFM was 30.6% in 2012–2013 and 21.5% in 2017–2018 PDHS. Both PDHSs reported a significantly higher prevalence of CFM in Sindh and Baluchistan compared with other regions of Pakistan. Improved socioeconomic status significantly reduced the odds of various types of CFM, except the coexistence of underweight with wasting. The high prevalence of CFM in Pakistan can be averted by multisectoral collaboration and by integrating nutrition-sensitive and nutrition-specific interventions.

Pathways to Improving Nutrition among Upland Farmers through Nutrition-Sensitive Agriculture Interventions: A Case from Northern Laos

While there is an increased awareness of the role of nutrition-sensitive agriculture (NSA) interventions on nutrition, the studies that investigate holistic pathways from interventions to nutrition outcomes are inadequate. We aimed to understand these pathways to improved nutrition from the Enhancing Nutrition of Upland Farming Families (ENUFF) Project implemented in northern Laos. We applied an embedded case study design by recruiting 101 participants representing implementers, school and private sector representatives, and beneficiaries, of which 34 participated in interviews and 68 participated in 11 FGDs. This was supplemented by a desk review of project documents. We analyzed the data using a directed content analysis across five pathways using a published framework on impact pathways from NSA interventions to nutrition outcomes. The project contributed to nutrition mainly through three core pathways-food production, nutrition and WASH-related knowledge, and agricultural income, supported by strengthening local institutions within the project’s scope. While it is evident that the project contributed to empowering women by saving their time and increasing income, further study is needed to investigate the translation of these aspects to nutrition-related practices. We also suggest the need to sustain the capacity of local institutions and their engagement beyond the project cycle. To enhance the effectiveness of NSA interventions on nutrition, there is a need to design and implement intervention package with multiple pathways and tailored strategies based on nutrition outcomes, the envisaged pathways, geographical context, and factors affecting these.

Impact of livestock interventions on maternal and child nutrition outcomes in Africa: A systematic review and meta-analysis protocol

The challenge of undernutrition (stunting and wasting) still remains a major health concern in children below 5 years of age in Africa, with the continent accounting for more than one third of all stunted children and more than one quarter of all wasted children globally. Despite the growing evidence on the role of agriculture interventions in improving nutrition, empirical evidence on the impact of livestock intervention on nutrition in Africa is scant. This review is aimed at determining whether livestock interventions are effective in reducing undernutrition in children below five years of age and in pregnant and lactating women in Africa. The review will be conducted according to PRISMA guidelines. Major electronic databases will be searched and complemented with grey and non-indexed literature from google and google scholar, and expert consultation for additional articles and reports. PICO criteria will be used while employing search strategies including MeSH, Boolean search operators and truncation/wildcard symbol to narrow or broaden the search. Articles on effect of livestock interventions on maternal and child nutrition conducted in Africa that meet the set inclusion criteria will be included in the review after critical appraisal by two independent reviewers. A standardized form will be used to extract data from included studies. The extracted data will be summarized and synthesized both qualitatively and quantitatively and key outcomes presented. Evidence generated from the systematic review and meta-analysis will be important for guiding nutrition sensitive livestock interventions and policies on nutrition programming, specifically on how to leverage on livestock interventions to reduce the burden of undernutrition.

Do agri-food market incentives improve food security and nutrition indicators? a microsimulation evaluation for Kenya

The sustainable development goal #2 aims at ending hunger and malnutrition by 2030. Given the numbers of food insecure and malnourished people on the rise, the heterogeneity of nutritional statuses and needs, and the even worse context of COVID-19 pandemic, this has become an urgent challenge for food-related policies. This paper provides a comprehensive microsimulation approach to evaluate economic policies on food access, sufficiency (energy) and adequacy (protein, fat, carbohydrate) at household level. The improvement in market access conditions in Kenya is simulated as an application case of this method, using original insights from households’ surveys and biochemical and nutritional information by food item. Simulation’s results suggest that improving market access increases food purchasing power overall the country, with a pro-poor impact in rural areas. The daily energy consumption per capita and macronutrients intakes per capita increase at the national level, being the households with at least one stunted child under 5 years old, and poor households living areas outside Mombasa and Nairobi, those which benefit the most. The developed method and its Kenya's application contribute to the discussion on how to evaluate nutrition-sensitive policies, and how to cover most households suffering food insecurity and nutrition deficiencies in any given country.
