Abstract

During the last decade, post-harvest losses (PHL) reduction has been topping the agenda of governments as a pathway for addressing food security, poverty, and nutrition challenges in Africa. Using survey data from 579 households, we investigated the factors that affect farmers’ decisions to adopt post-harvest technologies: mechanized shelling, drying tarpaulins, and airtight storage validated for reducing PHL in Tanzania’s maize-based systems, and the impacts on households’ food security and welfare. Mechanized shelling addressed a labor issue, while tarpaulins and airtight storage addressed product quality and quantity concerns. The results revealed large farm sizes and location in higher production potential zones (proxies for higher production scale) and neighbors' use of the technologies as universal drivers for adoption. Access to credit and off-farm income were unique determinants for airtight storage, while group membership increased the probability of adopting drying tarpaulin and airtight storage. The technologies have positive impacts on food security and welfare: drying tarpaulins and airtight storage significantly increased food availability (18–27%), food access (24–26%), and household incomes (112–155%), whereas mechanized shelling improved food and total expenditures by 49% and 68%, respectively. The share of total household expenditure on food decreased by 42%, 11%, and 51% among tarpaulin, mechanized shelling, and airtight storage adopter households, signaling significant improvements in food security and reductions in vulnerability. The results point to the need for policy support to enhance the adoption of these technologies, knowledge sharing among farmers, and financial resources access to support investments in the technologies.

采用改进的收获后技术对坦桑尼亚玉米农户粮食安全和福利的影响:一项比较评估

摘要在过去十年中，减少收获后损失(PHL)作为解决非洲粮食安全、贫困和营养挑战的途径一直是各国政府的首要议程。利用来自579个家庭的调查数据，我们调查了影响农民决定采用收获后技术的因素:机械化脱壳、干燥篷布和密封储存，这些技术在坦桑尼亚的玉米系统中被证实可以减少ph，以及对家庭粮食安全和福利的影响。机械化炮击解决了劳动力问题，而防水油布和密闭储存解决了产品质量和数量问题。结果显示，大型农场的规模和位置在更高的生产潜力区(代表更高的生产规模)，以及邻国对技术的使用是采用这些技术的普遍驱动因素。获得信贷和非农收入是密闭储存的唯一决定因素，而团体成员增加了采用干燥篷布和密闭储存的可能性。这些技术对粮食安全和福利产生了积极影响:干燥篷布和密闭储存显著提高了粮食供应(18% - 27%)、粮食获取(24% - 26%)和家庭收入(112-155%)，而机械化炮击分别提高了粮食和总支出49%和68%。在采用篷布、机械化炮击和密闭储存的家庭中，粮食支出占家庭总支出的比例分别下降了42%、11%和51%，这表明粮食安全和脆弱性得到了显著改善。研究结果表明，需要提供政策支持，以促进这些技术的采用，促进农民之间的知识共享，并提供财政资源，以支持对这些技术的投资。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
