PHYSICAL ECONOMIC AND SOCIAL WATER FOOTPRINT

The objective was to determine the water footprint (HHF) in its three variants: physical economic and social through physical (EFA) economic (EEA) and social (ESA) water efficiency indexes as well as the physical (PFA) economic (PEA) and social (PSA) productivity of water used in the production of apple (Malus domestica L.) Red Delicious variety produced in northern Mexico in the main producing states: Chihuahua Coahuila and Durango in 2022. Mathematical models of water efficiency and productivity were used for individual crops as well as at the aggregate level for several crops. The independent variables feeding the models were commercial-scale production data.
