Aquest dimecres 7 d'abril, la doctora Gara Villalba ha estat entrevistada al programa "En directe a Ràdio 4", coordinat per Josep Cabayol. L'efecte d'illa de calor ha estat el principal tema d'interès dels entrevistadors. Villalba ha explicat que l'efecte d'illa de calor pot provocar diferències de fins a 10°C a les nits d'hivern entre els nuclis urbans i la perifèria.

La dra Gara Villalba va participar el passat 17 de març en un debat a Vida Verda, de radio4. Juntament amb Annalisa Giocoli (arquitecta urbanista de l'Àrea Metropolitana de Barcelona), van debatre sobre el nexe entre l'energia, el menjar i aigua en el metabolisme urbà. Gara Villalba va explicar a Vida Verda com aconseguir una AMB més resilient mitjançant diferents estratègies.
The COVID-19 pandemic unveiled the fragility of food sovereignty in cities and confirmed the close connection urban dwellers have with food. Although the pandemic was not responsible for a systemic failure, it suggested how citizens would accept and indeed support a transition toward more localized food production systems.
Housing estates, that is, mass social housing on middle‐ and high‐rise apartment blocks, in urban areas are found all over the world with very similar constructive patterns and a multiplicity of environmental and socio‐economic problems. Boosting new urban spaces of resource production involves citizens in sites which face social and economic needs.
The Covid-19 pandemic newly brings food resilience in cities to our attention and the need to question the desired degree of food self-sufficiency through urban agriculture. We argue in this essay that this development has widely taken place due to three blind spots in urban planning.
Trends of extreme-temperature episodes in cities are increasing (in frequency, magnitude and duration) due to regional climate change in interaction with urban effects. Urban morphologies and thermal properties of the materials used to build them are factors that influence.
Urban agriculture, while being a promising solution to increase food sovereignty in cities, can lead to an unprecedented discharge of nutrient and fertilizer-related emissions into the urban environment. Especially relevant are nitrogen (N) and phosphorus (P), due to their contribution to marine and freshwater eutrophication.
Optimizing urban resources through circular economy principles offers the opportunity to close loops and improve production systems, but an assessment of these systems through a combination of circularity and environmental tools is missing from the literature.
A lot of good science is being presented at AGU Fall Meetting 2020. Some of the presentations are focused in the COVID-19 pandemic. The URBAG group presented a poster presentation that wants to reflect upon lessons learned from the COVID-19 mitigation measures in terms of reduced mobility and its effect on urban air pollution.
Urban agriculture systems can significantly contribute towards mitigating the impacts of inefficient and complex food supply chains and increase urban food sovereignty. Moreover, improving these urban agriculture systems in terms of nutrient management can lead to a better environmental performance.
The effective integration of biodiversity, ecosystem functions and ecosystem services (ES) indicators into green infrastructure (GI) planning and conservation constitutes an important challenge for landscape and urban planners. In this study, we developed an operational framework for GI planning at the landscape scale in the Province of Barcelona.
Knowing the consumption patterns of the residents related to the occupation of the buildings and the family structure to which they belong. This study is part of central research of the Autonomous University of Barcelona with the collaboration of the city council of Badia del Vallès, which studies the urban metabolism of the municipality, being the typical housing estate built in the 70s.
