Deployment of urban agriculture in East Lima, Peru.

Urban agriculture in Lima has been promoted by the project Farmers in the city encompassed in the Urban harvest program promoted by the Consultive Group on International Agricultural Research (CGIAR). The validation of the effectiveness of the project Farmers in the city can only be confirmed by maintenance over the time the deployment of the project goals. The project Farmers in the city was carried out by the International Potato Center (CIP) and GESPLAN research group of the Technical University of Madrid. The project was conducted at the East Cone of Lima, Peru, from 2006 to 2008. This communication shows the situation 5 years later. In order to know the current situation all the members of Cosanaca producer association, which was created under the project, have been interviewed. Besides, an expert panel was carried out with the responsible of the urban agricultural office of the municipalities that participate in the project. The results show that Cosanaca has duplicated the number of producers and that the municipalities have increased the number of workers

New profiles that are emerging within this field are also identified

Understanding the performance of an AnMBR treating urban wastewater and food waste via model simulation and characterization of the microbial population dynamics

[EN] An anaerobic membrane bioreactor (AnMBR) pilot plant treating kitchen food waste (FW) jointly with urban wastewater was run for 536 days. Different operational conditions were tested varying the sludge retention time (SRT), the hydraulic retention time (HRT) and the penetration factor (PF) of food waste disposers. COD removal efficiency exceeded 90% in all tested conditions. The joint treatment resulted in an almost 3-fold increase in methane production (at 70 days of SRT, 24 h HRT and 80% PF) in comparison with the treatment of urban wastewater only. Mathematical model simulations and Illumina technology were used to obtain in-depth information of this outstanding process performance. Both the PF and SRT factors increased influent biodegradability. The experimental results were accurately reproduced via model simulations modifying only the influent biodegradability. The high SRT and the presence of ground FW in the influent resulted in higher hydrolytic activity. Not only did the Archaea population increase 3-fold but Levilinea genera was also significantly raised. Three new genera characterised by anaerobic fermentation of amino acids (Leptolinea, Aminomonas and Aminobacterium) were among the ten most abundant of the total sequences identified during the joint treatment, indicating an improvement in the hydrolysis step of anaerobic degradation. Influent biodegradability remained at high values when FW addition stopped.This research work has been financially supported by the Generalitat Valenciana (PROMETEO/2012/029 PROJECT), which is gratefully acknowledged.Durán Pinzón, F.; Zamorano -López, N.; Barat, R.; Ferrer, J.; Aguado García, D.

Influence of Food Waste addition over microbial communities in an Anaerobic Membrane Bioreactor plant treating urban wastewater

[EN] Notorious changes in microbial communities were observed during and after the joint treatment of wastewater with Food Waste (FW) in an Anaerobic Membrane Bioreactor (AnMBR) plant. The microbial population was analysed by high-throughput sequencing of the 16S rRNA gene and dominance of Chloroflexi, Firmicutes, Synergistetes and Proteobacteria phyla was found. The relative abundance of these potential hydrolytic phyla increased as a higher fraction of FW was jointly treated. Moreover, whereas Specific Methanogenic Activity (SMA) rose from 10 to 51 mL CH4 g(-1) VS, Methanosarcinales order increased from 34.0% over 80.0% of total Archaea, being Methanosaeta the dominant genus. The effect of FW over AnMBR biomass was observed during the whole experience, as methane production rose from 49.2 to 144.5 L CH4 . kg(-1) influent COD. Furthermore, biomethanization potential was increased over 82% after the experience. AnMBR technology allows the established microbial community to remain in the bioreactor even after the addition of FW, improving the anaerobic digestion of urban wastewater. (C) 2018 Elsevier Ltd.

Maximizing resource recovery from urban wastewater through an innovative facility layout

[EN] This research work proposes an innovative layout for urban wastewater treatment based on anaerobic technology, microalgal cultivation and membrane technology. The proposed Water Resource Recovery Facility (WRRF) system can treat urban wastewater efficiently, complying with legal discharge limits and allowing for resource recovery, i.e. energy, nutrients and reclaimed water. In addition, the proposed layout produces less solid wastes than a conventional wastewater treatment plant (WWTP) and it is possible to recover energy as biogas, not only from the original wastewater sources but also from the biomass generated in the WRRF system

Resource recovery from sulphate-rich sewage through an innovative anaerobic-based water resource recovery facility (WRRF)

[EN] This research work proposes an innovative water resource recovery facility (WRRF) for the recovery of energy, nutrients and reclaimed water from sewage, which represents a promising approach towards enhanced circular economy scenarios. To this aim, anaerobic technology, microalgae cultivation, and membrane technology were combined in a dedicated platform. The proposed platform produces a high-quality solid- and coliform-free effluent that can be directly discharged to receiving water bodies identified as sensitive areas. Specifically, the content of organic matter, nitrogen and phosphorus in the effluent was 45 mg COD.L-1 , 14.9 mg N.L-1 and 0.5 mg P.L-1 , respectively. Harvested solar energy and carbon dioxide biofixation in the form of microalgae biomass allowed remarkable methane yields (399 STP L CH 4.kg(-1) CODinf ) to be achieved, equivalent to theoretical electricity productions of around 0.52 kWh per m 3 of wastewater entering the WRRF. Furthermore, 26.6% of total nitrogen influent load was recovered as ammonium sulphate, while nitrogen and phosphorus were recovered in the biosolids produced (650 +/- 77 mg N.L-1 and 121.0 +/- 7.2 mg P.L-1).This research was supported by the Spanish Ministry of Economy and Competitiveness (MINECO, Projects CTM2014-54980-C2-1-R and CTM2014-54980-C2-2-R) jointly with the European Regional Development Fund (ERDF), which are gratefully acknowledged.

Desarrollo de algoritmos predictivos por inteligencia artificial (Deep-learning) para asegurar el éxito del alumno

Breve descripción La adaptación de los planes de estudio a la normativa y a los criterios propuestos por el Espacio Europeo de Educación Superior (EEES) ha conllevado un importante reto de innovación pedagógica, y cambios significativos en el proceso enseñanza-aprendizaje. El sistema universitario español acumula ya una trayectoria y un bagaje importante de experiencias, buenas prácticas e innovaciones que se han ido encaminando hacia la continua mejora de la calidad de la formación ofertada. El proceso de cambio en el que está inmersa hoy en día la Educación Superior demanda nuevos sistemas y procedimientos de enseñanza y evaluación. Dos de los cambios derivados de la implantación del EEES son la elaboración de los plantes de estudio por competencias generales, transversales y específicas, y el diseño de herramientas e iniciativas de mejora de la calidad de los programas formativos, entre otros aspectos. En el contexto anterior, en el presente proyecto se han aplicado una serie de herramientas tecnológicas con el objetivo de mejorar la actividad docente que pretenden implantarse de forma transversal entre asignaturas del grado de Nutrición y Dietética Humana de la Facultad de Medicina de la Universidad Complutense. Además, esta novedosa iniciativa podría utilizarse en cualquier asignatura de cualquier grado de cualquier Facultad de la Universidad Complutense o incluso de otras Universidades. En concreto, el proyecto identifica al comienzo del curso académico a aquellos/as alumnos/as que tendrán dificultades para superar diferentes asignaturas del grado de Nutrición y Dietética Humana, para que el profesorado tome diferentes medidas docentes preventivas desde el mismo comienzo del curso académico. La identificación de estos alumnos al comienzo del curso académico se realizó mediante técnicas de inteligencia artificial para generar un algoritmo de predicción autoalimentado, considerando fundamentalmente una serie de parámetros académicos de los alumnos/as. El proyecto busca reforzar el aprendizaje de los/as alumnos/as que presenten dificultades en superar una asignatura. Esta iniciativa Innova-Docencia es una propuesta innovadora, que conlleva la realización de una actividad común en el que han intervenido personal PDI, PAS y estudiantes
