Demands for food, water, and energy will continue increasing as the worldâ€™s population expands and incomes rise in many developing countries. National and provincial governments will be challenged to ensure that land, water, and energy resources are managed wisely to support economic development and to provide the foundation for continuously improving food security at household and national levels. Some authors suggest that public officials should consider virtual water and water footprints when evaluating strategies and policies that in uence farm-level access to key resources and regional production patterns. Others suggest that the analysis of virtual water and water footprints is not sufficient for determining optimal strategies or guiding policy decisions. We describe the inherent limitations of virtual water and water footprint analysis, which arise la largely from the failure to account for the opportunity costs of water and other essential factors of production.
