| Sumario: | In the western External Betics several temporal saline water bodies (playa-lakes) constitute singular environments that are pro-tected due to their ecological and hydrological values. Changes in their hydrological status due to both natural and human-induced changes alter the characteristics of their sediments. A detailed de-termination of the pH and electrical conductivity in the sediments of six playa-lakes within a range of degradation statuses was made in this study. The detailed examination of such geochemical variables has allowed us to establish three categories of degradation in the studied systems. Our results highlight the extreme vulnerability of this playa-lakes caused mainly by human activities, particularly tho-se related to land-use change for agriculture, as well as the necessity of its protection based on scientific criteria |
