Food-energy-water nexus of different cacao production systems from a LCA approach

Agroforestry, especially organic, outperforms monoculture in sustainable cocoa production.

A recent study by Armengot et al. examines the environmental impacts of different cocoa production systems, focusing on smallholder contexts. The research compares four young cacao systems: conventional monoculture, organic monoculture, conventional agroforestry, and organic agroforestry. Using a life cycle assessment (LCA) approach, the study evaluates the food-energy-water nexus and ten environmental impact categories, such as carbon footprint and water use. The findings reveal that agroforestry systems, especially when managed organically, have better environmental performance than conventional monocultures. Agroforestry systems showed higher energy efficiency, lower use of non-renewable resources, and reduced environmental impacts, despite slightly higher water footprints due to lower yields in the early years. For smallholder farmers, adopting agroforestry practices and organic management can lead to more sustainable cocoa production, improved energy efficiency, and diversified income sources from additional crops like bananas and timber trees. The study highlights the importance of diversifying production and implementing cultural practices such as pruning and organic fertilization to enhance sustainability in cocoa farming.
