Efficiency and productivity of water

The objectives were to determine the physical (PFA), economic (PEA) and social (PSA) productivity, as well as the physical (EFA), economic (EEA) and social (ESA) efficiency of water used in the production of pecan nut (Carya illinoensis) and contrast it against apple (Malus domestica) in the state of Chihuahua in 2019, both crops produced under medium technology use (MT) conditions. Models of productivity and water efficiency in the agricultural sector were used, feeding these models with production data at the commercial level from SIAP. The results indicate that the PFA, PEA and PSA were (always MT walnut vs MT apple): 0.15 and 2.28 kg m-3, USD 126,897 and USD 619,570 profit per hm3 and 9 and 23 jobs per hm3, while the EFA, EEA and ESA were: 6,603 and 438 liters kg-1, 7.88 and 1.61 m3 of water used per USD of profit and 113,143 and 42,562 m3 of water used per job. The indicators show that in physical, economic and social terms, water use in production is less productive (therefore less efficient) in walnut.
