Produce or Buy: Impacts of Citrus Farming and Crop Diversification on Household Dietary Diversity in Guangxi, China
Abstract
In recent decades, China has made significant strides in food and nutrition security, yet challenges persist in the western rural regions, especially in Guangxi. Farming households in this area face heightened vulnerability due to limited arable land and environmental hazards, leading to increased efforts to boost income through horticultural crop farming. This study explores the impact of citrus farming and crop diversification on household dietary diversity within the context of the existing literature, examining trade-offs between subsistence and income-generating farming. Using OLS regression techniques and a mediating effect model, the analysis focuses on distinct contexts within citrus farming, utilizing survey data from households engaged in the cultivation of both citrus and non-citrus. Results reveal that while citrus cultivation moderately contributes to dietary diversity, its primary influence lies in encouraging farmers to diversify food purchases, with the mediating effect from market purchases exceeding 50%. Diversifying crop production, including staple crops and vegetables alongside citrus, proves more effective in enhancing dietary diversity among citrus farming households. Crop diversification positively influences dietary diversity, partially addressing household self-sufficiency. While extensive crop diversification may not be the ultimate solution to food security challenges, promoting specific diversification systems shows promise in the context of sustainable agriculture goals.
