Small island developing states face challenges in cultivating healthy food systems and are currently bearing substantial burdens of obesity and type 2 diabetes. Local food production—rooted in collective local and Indigenous traditions, self-sufficiency, and climate-adaptive agricultural practices—has long emphasised a fibre-rich, plant-based diet; however, common histories of dietary colonialism have replaced local, small-scale farming and fisheries with non-nutritive cash crops, intensive livestock operations, and high-quality food exportation.

Background Information about the global structure of agriculture and nutrient production and its diversity is essential to improve present understanding of national food production patterns, agricultural livelihoods, and food chains, and their linkages to land use and their associated ecosystems services. Here we provide a plausible breakdown of global agricultural and nutrient production by farm size, and also study the associations between farm size, agricultural diversity, and nutrient production.
