In addition, acriterion has been found to identify the intensive exploitation of aquifers. This allows for considering those volumes as non-renewable resources, when applicable, in processes to define integrated water resources management.The transformity weighted mean of water resources due to chemical potential energy in the SCR basin(9.32E + 06 sej/J for surface water and 6.47E + 06 sej/J for groundwater) was greater than in the UCLRbasin (5.75E + 05 sej/J for surface water and 2.83E + 05 sej/J for groundwater). Nevertheless, based on the analysis of the variation in emergy, some strategies were identified to improve the efficiency of the joint management of water resources. Standing out among these is the determination of a monthly variability in the volumes of water provided, making it possible to observe a decrease in emergy per unit volume in the SCR basin and an increase in the percentage of renewable resources in the UCLR basin. | Other Identifiers: | http://hdl.handle.net/20.500.11799/58661 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
