The article emphasizes the critical need to address the water-food-carbon nexus for sustainable agriculture amidst water scarcity and climate change. Agricultural practices consume large water volumes and generate significant greenhouse gases (GHGs), with consumer food choices indirectly influencing these impacts. Regional dietary patterns further complicate sustainability efforts. The review highlights the importance of reducing water use and GHG emissions in agriculture, promoting plant-based diets for environmental and health benefits, and incorporating comprehensive footprint assessments and socio-hydrology in future research.
