Recommended daily allowance-based contribution of household’s own agricultural production to food and nutrition security in Karamoja sub-region of Uganda

Abstract

Abstract Background In Uganda, agriculture is the main pathway for dietary intake among the households. Karamoja sub-region, located in Northeastern part of Uganda is the most food insecure in the country. Although agriculture contributes greatly to Uganda’s food systems, there is inadequate evidence for household energy and nutrient intake from agricultural production in the sub-region. Karamoja sub-region is typical because crop production has increasingly become part of the agricultural system in a largely semi-arid environment, predominantly occupied in pastoralism. Therefore, a cross-sectional study of 520 participants investigated the contribution of household’s own agricultural production to dietary intake, seeking to answer whether or not own agricultural production translates into adequate energy and nutrient intake. Results Own food production did not meet energy and nutrient requirements, contributed disproportionately among the districts to household cumulated annual RDAs. This was reflected in the higher proportion of households in Moroto not attaining the cumulative annual RDA (energy: 100.0; protein 100.0; iron 86.5; and zinc 100.0%) than in Abim (energy: 81.6; protein 53.3; iron 23.7; and zinc 59.9%). Overall in Karamoja sub-region, the total energy and nutrients required by the household and supplied from their agricultural production were 15,589.7 ± 10,230.6 and 4226.0 ± 3980.1 kcal/day for energy, 317.6 ± 202.6 and 154.4 ± 153.7 g/day for proteins, 49.5 ± 30.8 and 50.2 ± 47.6 mg/day for iron, and 52.7 ± 32.6 and 25.4 ± 24.5 mg/day for zinc. Inter-household distribution of the absolute difference between energy and selected nutrients required by the household and that derived from own agricultural production showed deficits in household energy and nutrients needs. Further, polygamy, subsistence farming by spouse, lack of formal education by spouse positively predicted energy and nutrient supplied from own agricultural produce while lack of formal education negatively predicted energy nutrients supplied from agricultural produce. Increase in household size increased energy and nutrient required from agricultural production. Conclusion Own agricultural production contributes limitedly to household energy and nutrient needs in the sub-region. There are great variations in the households’ capacity to derive energy and nutrients from own agricultural produce in Karamoja sub-region. Polygamy, subsistence farming, education and household size predicted energy and nutrients required from and supplied by agricultural production.
