Unraveling Tanzania’s Breadbasket Paradox In Child Nutrition

Tanzania's "Breadbasket Regions (BBRs)" are nan halfway of nan country's nutrient supply, contributing complete 38% of Tanzania's nationalist maize production. However, nan 2018 National Nutrition Survey revealed a paradox: nan 5 regions pinch nan highest rates of kid stunting and terrible malnutrition successful nan state are each located wrong these high-agricultural-yield areas. This "breadbasket paradox" has raised concerns: why are children successful awesome food-producing regions much prone to maturation issues than those successful non-food-producing regions?

Recently, Professor Xu Tian from nan College of Economics and Management astatine China Agricultural University, successful collaboration pinch Mosses Lufuke from nan Department of Economics astatine nan University of Dodoma successful Tanzania, uncovered nan underlying reasons done information analysis. The related article has been published successful Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025645).
The investigation squad utilized broad information from Tanzania's 2017-2018 National Household Budget Survey, 2020-2021 National Integrated Labor Force Survey, and 2020-2021 National Panel Survey, covering 7360 households, to analyse nan narration betwixt harvest accumulation and children's maturation status. Unlike erstwhile studies that relied connected descriptive statistics, this study employed Propensity Score Matching (PSM) and instrumental adaptable models, controlling for confounding factors specified arsenic family income, family size, and urban-rural differences, to verify nan authenticity of nan "breadbasket paradox" from a statistical perspective.

The results showed that nan stunting complaint among children successful BBRs was importantly higher than that successful non-BBRs. More importantly, location were location differences successful nan effect of harvest accumulation connected kid nutrition: successful non-BBRs, higher nutrient accumulation importantly reduced nan consequence of kid stunting and improved tallness development; however, successful BBRs, this affirmative effect was not significant—even pinch accrued production, children's maturation position did not amended accordingly.

To research nan causes of this paradox, nan investigation squad analyzed 2 imaginable mechanisms. The first was "maternal moving hours": does higher accumulation lead mothers to participate much successful cultivation work, thereby reducing nan clip spent caring for children? Data showed that location was nary important relationship betwixt harvest accumulation and mothers' out-of-home moving hours successful either BBRs aliases non-BBRs, truthful this presumption was not supported.

The 2nd system was "dietary diversity": does higher accumulation consequence successful a much monotonous family diet? The study recovered that successful non-BBRs, accrued nutrient accumulation did lead to greater family dietary diversity, which was straight related to improved nutrition; however, successful BBRs, contempt higher production, location was nary important summation successful family dietary diversity. This whitethorn beryllium related to nan precocious grade of cultivation commercialization successful BBRs—farmers thin to cultivate azygous rate crops for waste alternatively than increasing a assortment of foods for their ain consumption, starring to nan arena of "high accumulation but monotonous diet".

The study pointed retired that simply expanding nutrient accumulation is insufficient to lick nan problem of kid malnutrition, particularly successful regions pinch a precocious grade of cultivation commercialization. Tanzania's existent cultivation policies whitethorn overemphasize accumulation increases while neglecting nan cardinal domiciled of dietary diverseness successful children's growth. The study suggested that early policies could beryllium adjusted successful 3 aspects: first, encouraging farmers successful BBRs to turn a assortment of crops to equilibrium economical benefits and family consumption; second, strengthening nan building of cultivation merchandise markets to alteration farmers to get income by trading rate crops to acquisition a assortment of foods; third, specifically improving nan allocation of family resources, specified arsenic helping women trim nan load of non-agricultural activity for illustration water-fetching, to guarantee they person clip to hole nutritious food.
