Abstract
This study documented the diversity, nutritional composition, community-based prioritisation, and agroecological adaptation of wild edible vegetable species (WEVs) in Aceh, Indonesia, to identify candidate taxa for targeted integration into low-input farming systems consistent with the principles of biological husbandry. Field surveys in three regencies employed stratified purposive sampling and participatory interviews with 120 respondents to evaluate species against seven selection criteria, after which the ten highest-ranked taxa were analysed for proximate and mineral composition and assessed for tolerance to drought, flooding and shade. A total of 31 WEVs were recorded across lowland and riparian habitats, with Diplazium esculentum (32.8), Ipomoea aquatica (31.9), Psophocarpus tetragonolobus (31.3) and Centella asiatica (31.3) emerging as top priorities. Protein content ranged from 2.78% to 3.82% FW, calcium from 80 to 340 mg 100 g−1 DW and iron from 270 to 437 mg kg−1 DW, while potassium was the most abundant macro-mineral (4800–6200 mg 100 g−1 DW), with the highest concentrations in Psophocarpus tetragonolobus and Ipomoea aquatica. Cluster analysis grouped species into dryland gardens, wetland margins and shaded agroforestry systems. These underutilised vegetables may contribute to diversified diets, climate-resilient production and multifunctional landscapes when integrated into low-input farming systems, subject to validation through on-farm trials. The findings aligned with the UN Sustainable Development Goals 2, 13 and 15, highlighting ecologically grounded pathways to strengthen biological agriculture in tropical smallholder contexts.
