Abstract

In the context of accelerating climate change (CC), this study empirically examines climatic variations’ impact on household dietary diversity (DD) in India. The analysis period spans 2014–2020 and includes approximately 1.04 million observations from 198,238 households. We use linear and quadratic regressions under multiple model specifications (pooled, fixed effect, and fractional) to obtain robust results. Our results indicate that temperature anomalies positively impact DD up to a threshold, after which the relationship turns negative. However, the effect of precipitation variation is inconclusive. Furthermore, rising humidity undermines DD. This paper contributes to the literature on climatic variations and food insecurity by exploring whether Indian households are adapting to climatic variations. Anomalies show heterogeneous impacts on DD depending on the baseline climate and households’ socioeconomic characteristics. Climatic variation is expected to exacerbate existing vulnerabilities in food systems; thus, our findings underscore the urgency for climate-adaptive strategies to safeguard food security, particularly in developing nations vulnerable to CC impacts.

面对气候变化的饮食多样性：印度家庭的视角

在气候变化加速的背景下，本研究实证考察了气候变化对印度家庭饮食多样性的影响。分析期间为2014-2020年，包括来自198,238个家庭的约104万份观察报告。我们在多个模型规格（池化、固定效应和分数）下使用线性和二次回归来获得稳健的结果。我们的研究结果表明，温度异常对DD的影响达到一个阈值后，关系变为负相关。然而，降水变化的影响尚无定论。此外，上升的湿度会破坏DD。本文通过探索印度家庭是否适应气候变化，为气候变化和粮食不安全的文献做出了贡献。根据基线气候和家庭的社会经济特征，异常对DD的影响不尽相同。预计气候变化将加剧粮食系统现有的脆弱性；因此，我们的研究结果强调了制定气候适应战略以保障粮食安全的紧迫性，特别是在易受气候变化影响的发展中国家。

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.
