Two presentations from URBAG members have been shared in the latest EGU's annual General Assembly EGU22, hosted in Vienna, Austria. Thanks to the hybrid format, over 14,000 attendees from 116 countries have shared each work throughout the week-long conference from 23-27 May 2022.
URBAG ha participat de nou aquest any en el programa Bojos per la Ciència de la Fundació Catalunya-La Pedrera. On conjuntament amb el Departament d’Enginyeria Química, Biològica i Ambiental de la UAB imparteixen el programa Bojos per la Terra.
Green roofs provide a good opportunity for creating new green spaces in urban dense areas and offer a wide range of benefits. The city of Oslo has ambitious plans for improving its environmental performance in aspects such as energy consumption, water management and greenhouse gas emissions.
Des de l'Institut de Ciències i Tecnologies Ambientals de la UAB (ICTA-UAB) estem realitzant tallers pedagògics en els quals l'alumnat de primària aprendrà més sobre el CO2 i els seus efectes al planeta Terra. L'alumnat es convertirà en explorador per millorar el món, ja que el CO2 és responsable de l'escalfament de la Terra i les ciutats en produeixen molt.
Title: Mapping direct N2O emissions from peri-urban agriculture: The case of the Metropolitan Area of Barcelona / Geographically explicit datasets reflecting local management of crops are needed to help improve direct nitrous oxide (N2O) emission inventories. Yet, the lack of geographically explicit datasets of relevant factors influencing the emissions make it difficult to estimate them in such way.
Title: Sensitivity study of PBL schemes and soil initialization using the WRF-BEP-BEM model over a Mediterranean coastal city / Due to increased urbanization and global warming, cities are experiencing more heat wave (HW) events that cause extreme heat stress. To mitigate such effects, a better understanding of the impact of urban morphology on the boundary layer development is needed.
URBAG is using a Picarro G2301 station that measures CO2, CH4 and H20 from the ceiling of the ICTA-UAB. Located at a height of 147m above sea level, the station takes measurements every 10 seconds based on the cavity ring-down spectroscopy technique. This data is open to everyone by clicking on the image below, where you will also find more technical specifications.
Title: A take-home message from COVID-19 on urban air pollution reduction through mobility limitations and teleworking / The rigorous traffic limitations during COVID-19 have forced many people to work from home, reaching an outstanding degree of teleworking and reduction in air pollution
Title: Recovered phosphorus for a more resilient urban agriculture: Assessment of the fertilizer potential of struvite in hydroponics / Urban agriculture (UA) is a means for cities to become more resilient in terms of food sovereignty while shortening the distance between production and consumption. However, intensive soilless UA still depends on the use of fertilizers, which relies on depleting non-renewable resources.
Title: Optimizing irrigation in urban agriculture for tomato crops in rooftop greenhouses / The rise of population in urban areas makes it ever more important to promote urban agriculture (UA) that is efficient in terms of water and nutrients. How to meet the irrigation demand of UA is of particular concern in urban areas where water sources are often limited.
Green corridors (Eixos Verds in Catalan) are urban strips with a high presence of vegetation that cross the urban fabric and link the different areas of the city. Currently, the Metropolitan Area of Barcelona (AMB) bares the potential to create more than 750 km.
The cartography of Local Climate Zones (LCZ) of Barcelona has been published in the lcz-generator repository. Elaborated by Joan Gilabert.
