Productivity and efficiency of water used Jose Luis Rios Flores

The objective was to determine the number of indicators of profitability and physical (PFA), economic (PEA) and social (PSA) productivity of water used in production, as well as indicators of physical (EFA), economic (EEA) and social (ESA) efficiency of water in the pecan nut (Carya illinoensis) crop in the state of Coahuila, Mexico. The methodology consisted in the use of mathematical models of PFA, PEA and PSA fed with data from the Agricultural and Fishery Information System (SIAP) and FIRA (Fideicomisos Instituidos en Relación con la Agricultura) that allowed estimating PFA, PEA and PSA. The results show that the PFA, PEA and PES of the pecan nut crop (Carya illinoensis) were the following: the PFA was equal to: 0.6038 kg m-3, the PEA was equal to USD 0.0116 profit per m3, and the PES was equal to 7.11 jobs hm-3. The EFA, EEA and ESA were equal to 18.169 m3 kg-1, 86.484 m3 per USD gain and 140,560 m3 job-1 respectively.
