Abstract

Farm production diversification is widely recognized as a promising pathway to enhance household dietary diversity and food security, though its effectiveness varies across ecological and socioeconomic contexts. This study investigates the relationship between farm production diversity and household dietary diversity and food security in five climate-vulnerable districts of southern Bangladesh. Data were collected from 768 households between April and June 2023 using structured surveys stratified by salinity zones. Dietary diversity was measured through household dietary diversity scores and food variety scores, while food insecurity was assessed using the Household Food Insecurity Access Scale. Farm production diversity was quantified by the number of food groups produced, the Shannon diversity index, and food crop diversity. Poisson and ordered probit regression models were applied to estimate associations, controlling for market access, off-farm household income, household demographics, and environmental factors. The results reveal that greater production diversity is modestly but significantly associated with improved dietary diversity and reduced food insecurity, particularly in low and medium salinity zones. In high salinity areas, these associations were weaker or statistically insignificant, likely reflecting environmental constraints limiting production options. Market access, off-farm household income, education, and household size also played significant roles. These findings underscore the need for context-specific strategies that integrate production diversification with climate-resilient technologies, livelihood diversification, and improved market access to strengthen food security in climate-vulnerable rural communities.

农业生产多样性在加强孟加拉国南部饮食多样性和粮食安全方面的作用

农业生产多样化被广泛认为是增强家庭膳食多样性和粮食安全的一个有希望的途径，尽管其有效性因生态和社会经济背景而异。本研究调查了孟加拉国南部五个气候脆弱地区的农业生产多样性与家庭饮食多样性和粮食安全之间的关系。2023年4月至6月期间，通过按盐度区分层的结构化调查，从768个家庭收集了数据。膳食多样性通过家庭膳食多样性得分和食物种类得分来衡量，而粮食不安全状况则通过家庭粮食不安全获取量表来评估。农业生产多样性通过生产的粮食类群数量、香农多样性指数和粮食作物多样性来量化。在控制市场准入、非农家庭收入、家庭人口统计和环境因素的情况下，应用泊松和有序probit回归模型来估计相关性。结果表明，更大的生产多样性与饮食多样性的改善和粮食不安全的减少有轻微但显著的联系，特别是在低和中等盐度地区。在高盐度地区，这些关联较弱或统计上不显著，可能反映了环境限制限制了生产选择。市场准入、非农家庭收入、教育程度和家庭规模也发挥了重要作用。这些发现强调需要制定因地制宜的战略，将生产多样化与气候适应型技术、生计多样化和改善市场准入相结合，以加强气候脆弱农村社区的粮食安全。

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.
