Nueva iniciativa de gestión del uso del suelo (NIGEUS) fundamentada en los enfoques ecosistémico, integrador, participativo y holístico, en el centro-norte de Nicaragua (municipios de Waslala, El Cuá y El Tuma-La Dalia)
There are approximately 608 million farms in the world, of which 84% are small farms and produce 35% of the world's food. Various training programs have been promoted by different organizations to achieve a more sustainable ...
Operation and control of high rate activated sludge process in urban wastewater treatment plants
This doctoral thesis focuses on the High Rate Activated Sludge (HRAS) process, which emerges as an alternative to the primary clarifier in activated sludge systems (CAS) to reduce energy consumption, analysing its effects ...
Electro bioremediation of nitrate contaminated groundwater: from laboratory to on site pilot plant
Water stands out as the most essential resource currently under serious threat. The combination of water scarcity and increasing pollution of available water poses significant challenges to governance and society. Typically, ...
Roadmap for scaling up thermophilic CO2 bioreduction to acetate : shedding light on using surplus renewable energy and industrial off gases
Carbon dioxide (CO2) is largely emitted in the ignition of fossil fuels for transport, electricity generation or other industrial processes. CO2 is an inorganic compound that exists naturally on Earth, but its concentration ...
La conservación del patrimonio natural geológico en campos volcánicos, una herramienta para la gestión sostenible del territorio. El caso de la zona volcánica de la Garrotxa
The study of the geodiversity of an area and the conservation of its geological heritage, unlike biodiversity, has only recently begun to be systematized. This thesis analyses the conservation of geological heritage in ...
Agua, actores sociales y servicios de los ecosistemas en la cuenca del río Muga. Una aproximación socioecológica
This doctoral thesis aims to identify and characterize the relationships between stakeholders and water resources through the sociocultural and spatial analysis of the water ecosystem services (WES) in the social-ecological ...
Percepción del cambio climático y medidas de ahorro de agua en alojamientos turísticos de la cuenca del río Muga (Girona, España)
This thesis analyses the perception of climate change and problems with water perceived by lodging industry. 33 in-depth interviews to owners or managers of hotels, campsites and rural lodgings of the Muga river basin have ...
Steering CO2 bio-electrocycling into valuable compounds through inline monitoring of key operational parameters
Microbial Electrochemical Technologies (METs) are a promising alternative for capturing and in-situ reducing CO2 through the use of renewable electricity. Microorganisms grown in autotrophic conditions use CO2 as an electron ...
Els prats de dall de la terra baixa catalana. Caracterització geobotànica, valoració agroambiental i estudi de les relacions fitosociològiques entre els prats dalladors de l'Europa occidental
The hay meadows in the Mediterranean region of Catalonia. Geobotanical characterisation, agri-environmental assessment, and study of the phytosociological relationships between hay meadows in Western Europe We locate ...
Abatement of siloxanes in sewage biogas: coupling adsorption and biological treatments
The anaerobic digestion of organic matter causes the formation of biogas that can be used in energy conversion systems for the production of electricity and heat, injection into the gas grid or as a fuel. However, biogas ...
Assessment and optimisation of the operation of integrated membrane system for wastewater reclamation
The combination of two membrane technologies coupled together in series has become a standard technology when it comes to producing reclaimed water of high quality for potable reclamation or industrial applications. This ...
Taking advantage of autotrophic nitrogen removal: potassium and phosphorus recovery from municipal wastewater
Increasing awareness on the limited nature of the raw materials for the production of inorganic fertilizer is pushing for a shift from removal to recovery of nutrients from waste streams. In municipal wastewater treatment ...
Efectes del canvi global a les rouredes de Quercus petraea al NE de la Península Ibèrica
The sessile oak Quercus petraea is widespread in Central Europe. The populations in the NE Iberian Peninsula are at the southernmost limit of the species range, in the most Mediterranean-type conditions and at the xeric ...
Integrating computational fluid dynamics and biological model to assess wastewater reactor design
This doctoral thesis has integrated biological models (activated sludge models “ASM”) with simulation tools of computational fluid dynamics “CFD”, and has applied them to the design of two advanced technologies for wastewater ...
Sistema d'ajut a la decisió per la selecció de sistemes de sanejament
The selection of the most appropriate wastewater treatment involves a complex decision making process. For that reason, some tools have been developed in recent years in order to deal with this complexity, as Novedar_EDSS ...
Paisatges de frontera dels territoris de pas dels Pirineus: els casos de l’àrea central de l’Espai Català Transfronterer i l’àrea central de l’Eurociutat Basca
Border landscapes often constitute geographical unities which have experimented distinct landscapes dynamics in each side of the border. This fact occurs because these border landscapes belong to different countries. The ...
Canvis recents en el consum i la gestió de l'aigua en espais turístics. El cas de la Costa Brava (Girona)
Tourism has become one of the most important economic sectors in the Mediterranean coast. Despite the economic benefits generated by tourism at local and regional level, the environmental impacts related to water consumption ...
Siloxane removal in the energy recovery of biogas: sequential adsorption/oxidation processes
The thesis deals with removal of organosilicon compounds in the energy recovery of biogas. Alternative adsorbents for the siloxane removal were studied, and the physical and chemical mechanisms involved in the siloxane ...
Bioelectrochemical transformation of carbon dioxide to target compounds through microbial electrosynthesis
In 2015 the average concentration of CO2 in the atmosphere exceeded 400 ppm. Some technologies, including CO2 capture and storage, are palliative. However, the development of alternatives to burning of fossil fuels focuses ...
Cultura campesina, cambio técnico y medio ambiente en el consejo popular "Cuatro Esquina" de Santa Lucía
The research subject comes as a result of the need to implement sustainable practices in agriculture, in order to confront the environmental deterioration. The research aspires to explain the relation between peasant ...
