Benefits of soil carbon: report on the outcomes of an international scientific committee on problems of the environment rapid assessment workshop
2014
The outcomes of the discussion in the four working sessions showed that although there is an urgent need to improve soil carbon management and stocks, and despite the existing knowledge about good agricultural practices to achieve this goal, these are not put into practice effectively and globally. The apparent contradiction has to do with a mismatch of policies at different societal and geographical scales, and the low policy profile of SOC. All participants agreed in the need to bring SOC into the core of environmental policies at all levels and to improve the governance of policy actions by addressing the stakeholders in a more effective way.

The role of freshwater copepods in the environmental risk assessment of caffeine and propranolol mixtures in the surface water bodies of Spain
2019
In this study we aimed at assessing: (i) the environmental risk posed by mixtures of caffeine and propranolol to the freshwater ecosystems of Spain; (ii) the sensitivity of freshwater copepod species to the two compounds; (iii) if the toxicity of caffeine and propranolol to freshwater copepods contributes to the environmental risk posed by the two compounds in the freshwater bodies of Spain. The environmental risk was computed as the ratio of MECs (i.e. the measured environmental concentrations) to PNECs (i.e. the respective predicted no-effect concentrations). The effects of caffeine and propranolol on the freshwater cyclopoid Diacyclops crassicaudis crassicaudis were tested both individua…

Radiometric correction effects in Landsat multi‐date/multi‐sensor change detection studies
2006
Radiometric corrections serve to remove the effects that alter the spectral characteristics of land features, except for actual changes in ground target, becoming mandatory in multi‐sensor, multi‐date studies. In this paper, we evaluate the effects of two types of radiometric correction methods (absolute and relative) for the determination of land cover changes, using Landsat TM and Landsat ETM+ images. In addition, we present an improvement made to the relative correction method addressed. Absolute correction includes a cross‐calibration between TM and ETM+ images, and the application of an atmospheric correction protocol. Relative correction normalizes the images using pseudo‐invariant fe…
Nuevas herramientas para promover la reutilización del agua regenerada: Un enfoque basado en la Economía Circular y el Pago por los Servicios Ambient…
2022
Las Estaciones Depuradoras de Aguas Residuales (EDARs) son una infraestructura necesaria dentro del ciclo del agua y de la gestión de los recursos hídricos, asegurando la correcta gestión de las aguas residuales, así como su vuelta al ecosistema. Comúnmente se ha considerado a la EDAR como el “punto final” del agua residual, donde el agua depurada se descarga en las masas de agua receptoras. Sin embargo, la posibilidad de utilizar ese caudal como fuente de agua en zonas con desequilibrios hídricos se convierte en una opción cada vez más defendida. La reutilización es una solución efectiva ante los desequilibrios hídricos, permitiendo que la EDAR sea considerada como fuente de agua no conven…
