The present article examines the livelihood benefits associated with agrobiodiversity in Veracruz, Mexico. Citrus-based agriculture is the principal economic activity in the agricultural sector of the state of Veracruz. It is practiced in mono-crop plantations by the majority of farmers, who are rendered vulnerable to price depreciation resulting from simultaneous harvest and over-supply of a single commodity. Some farmers have associated multiple crops in citrus farms (agroforestry techniques) as a strategy to improve their livelihoods. Farmers who increased agrobiodiversity in their farms have significantly improved their livelihoods compared to mono-crop plantation owners. The research shows that increased agro-biodiversity can be a strategy to improve the livelihoods of citrus producers in the state of Veracruz, with significant economic benefits depending on the crop combination: maize-citrus is the least economically profitable combination (providing 21% in terms of internal rate of return), while pineapple-citrus, banana-citrus and vanilla-citrus give higher returns (41%, 44% and 221% respectively). The citrus-vanilla crop combination also has the highest benefit-cost ratio, relative to citrus monocrop (1.91) as well as the highest net present value (MX$579,635.73). The choice of crop ultimately depends on the farmer's priorities. The associated benefits can be classified in three ways which correspond to the tripartite goal of sustainable development: (i) ecological sustainability (through increased ecosystem resilience), (ii) economic stability (through diversified, less risk-prone sources of income), and (iii) social well-being (through lower). 展开更多
