Title: Effect of land use changes on air quality: impacts of urbanization, urban vegetation, and agriculture / Urbanization converts natural landscapes into impervious surfaces, altering local climate and air quality. Greening strategies are adopted to mitigate these effects, yet their effectiveness depends on land use, urban form, geography, and climate interactions.
La publicació de l'investigador Ricard Segura-Barrero està tenint un gran impacte als mitjans. Les onades de calor i les sequeres cada vegada més freqüents estan reduint de manera preocupant la capacitat dels ecosistemes per actuar com a embornals de carboni.
Title: Co-benefits of nature-based solutions: A health impact assessment of the Barcelona Green Corridor (Eixos Verds) plan/ With the complete implementation of the Eixos Verds, 183 premature deaths could be averted annually (178 preventable deaths due to increase in GS alone, 5 preventable deaths through GS heat reductions), underscoring the critical role of urban greening in improving public health.
Title: Heat and Drought Events Alter Biogenic Capacity to Balance CO2 Budget in South-Western Europe/ Heat and drought events are increasing in frequency and intensity, posing significant risks to natural and agricultural ecosystems with uncertain effects on the net ecosystem CO2 exchange. The current Vegetation Photosynthesis and Respiration Model (VPRM) was adjusted to include soil moisture impacts on the gross ecosystem exchange and respiration.
Title: The food-water-climate nexus of green infrastructure: Examining ecosystem services trade-offs of peri-urban agriculture/ Emission reduction, heat mitigation, and improved access to water and food provision are increasingly critical challenges for urban areas in the context of global climate change adaptation and mitigation. The revival of local agricultural production is often lauded as a potential nature-based solution.
Title: Exploring how the heterogeneous urban landscape influences CO2 concentrations: The case study of the Metropolitan Area of Barcelona/ To understand the role these factors play in the distribution of CO2 over an urban area, we conducted a CO2 measurement campaign over the Metropolitan Area of Barcelona (AMB) over four urban land uses: impervious, green, forest, and agricultural.
On July 2023, URBAG participated at the International Conference of Industrial Ecology (ISIE) with two presentations. Juan David Arosemena presented his research which aims to determine the capacity and environmental impacts of supplying macronutrients such as nitrogen, phosphorus, and potassium from composting organic municipal solid waste. Gara Villalba presented the A decision approach to evaluate the design and implementation of green infrastructures in urban environments.
