Nature-based solutions (NBS) are increasingly employed to address urban challenges. Typically, NBS planning emphasizes environmental impacts and ecosystem services, often overlooking their role in addressing vulnerabilities. Our objective is develop a framework assessing the extent which alter For this, we relate service metabolism analyses spatially explicit The relies on multi-criteria decision analysis integrate diverse impacts. It follows stepwise approach including development of...
The Green Corridors Plan (Eixos Verds Plan), proposed by the Barcelona City Council, aims to enhance urban well-being, environmental sustainability, and resilience transforming one in every three streets into green corridors. Although initially designed for city-wide implementation, only first phase, focused on centric Eixample district, has been completed, overall plan implementation postponed. Our aim is evaluate health co-benefits of implementing citywide, focusing direct effects...
In Europe, the heterogeneous features of crop systems with majority small to medium sized agricultural holdings, and diversity rotations, require high-resolution information estimate cropland Net Ecosystem Exchange (NEE) its two main components Gross (GEE) Respiration (RECO). this context, paper presents an assimilation Sentinel-2 indices eddy covariance measurements at selected European flux sites in a new modified version Vegetation Photosynthesis Model (VPRM). VRPM is data-driven model...
The frequency and intensity of heat waves (HW) in cities are on the rise due to climate change as well urban fabric materials anthropogenic activities that affect accumulation. efficacy HW mitigation strategies depends a city's specific unique morphology, land use, building materials, geography. In this study, we show effectiveness cool roofs vegetation reducing temperature Metropolitan Area Barcelona (AMB). We use Weather Research Forecasting (WRF) model with scheme BEP+BEM, including11...
Abstract 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. This exceptional situation can be examined as a large-scale pilot test determine the potential improving urban quality through teleworking. Based on observed reductions lockdown Barcelona, we formulate socio-occupational scenarios, with various configurations teleworking, simulate them using chemistry transport...
Abstract Heat and drought events are increasing in frequency intensity, posing significant risks to natural agricultural ecosystems with uncertain effects on the net ecosystem CO 2 exchange (NEE). The current Vegetation Photosynthesis Respiration Model (VPRM) was adjusted include soil moisture impacts gross (GEE) respiration ( R ECO ) fluxes assess temporal variability of NEE over south‐western Europe for 2001–2022. Warming temperatures lengthen growing seasons, causing an increase GEE,...
Cities are hot spots on greenhouse gas (GHG) emissions, yet green infrastructure (GI) such as spaces and parks provides potential solution for reducing urban carbon footprints through photosynthetic uptake sequestration. Studies have shown that the offset of vegetation local anthropogenic CO2 emissions varies between 2% 100%, underscoring complexity associated with this solution. Quantifying CO2 capture by GI is challenging due to interplay respiration, seasonal variability,...
Terrestrial ecosystems play a crucial role in mitigating climate change by reducing greenhouse gas (GHG) emissions and sequestering significant amounts of atmospheric carbon dioxide (CO2). Wetlands, particularly coastal wetlands, are highly efficient sinks but can also be large sources methane (CH4). Natural agricultural such as rice paddies, contribute to 37 % global CH4 emissions. Monitoring wetland-atmosphere exchange is essential evaluate the effectiveness natural solutions (NCS),...
Due to increased urbanization and global warming, cities are experiencing more heat wave (HW) events that cause extreme stress. To mitigate such effects, a better understanding of the impact urban morphology on boundary layer development is needed. This study investigates sensitivity mesoscale simulations using WRF model coupled with building effect parameterization energy (BEP-BEM) at 1-km resolution 1) soil moisture initializations; 2) inclusion site-specific parameters; 3) planetary (PBL)...
Emission reduction, heat mitigation, and improved access to water food provision are increasingly critical challenges for urban areas in the context of global climate change adaptation mitigation. The revival local agricultural production is often lauded as a potential nature-based solution. However, an expansion peri-urban agriculture (peri-UA) may entail significant ecosystem trade-offs. This study explores impacts on food-water-climate nexus different scenarios semi-arid, Mediterranean...
Abstract. Tropospheric ozone (O3) is an important surface pollutant in urban areas, and it has complex formation mechanisms that depend on the atmospheric chemistry meteorological factors. The severe reductions observed anthropogenic emissions during COVID-19 pandemic can further our understanding of photochemical leading to O3 provide guidance for policies aimed at reducing air pollution. In this study, we use Weather Research Forecasting model with Chemistry (WRF-Chem) coupled canopy...
Monitoring CO2 concentrations in urban areas is crucial for determining the efficacy of climate change mitigation policies. However, highly heterogeneous land use, local geography, and convection patterns, which vary throughout landscape, complicate this task. To establish continuous monitoring programs, it important to first determine heterogeneity landscapes on ground. understand role these factors play distribution over an area, we conducted a measurement campaign Metropolitan Area...

We modified Vegetation Photosynthesis Respiration Model include soil moisture impacts gross (GEE) respiration (RECO) fluxes determine temporal variability of NEE over south-western Europe for 2001-2022. Warming temperatures lengthen growing seasons causing an increase GEE which is mostly compensated by a similar...

Abstract Carbonyl sulfide (OCS) is used to quantify the carbon capture potential of biosphere because its direct correlation with CO 2 uptake during photosynthesis. However, constrain urban signal, it necessary evaluate anthropogenic sources. We conducted two sampling campaigns in Metropolitan Area Barcelona (AMB), Spain, May (full COVID lockdown) and October 2020 measure spatial distribution variability OCS four land uses as follows: built, forest, park, peri‐urban agriculture.

Given that cities concentrate more than half of the global population, it becomes crucial to assess potential impacts future climate change on cities. This study employs Pseudo Global Warming (PGW) methodology replicate recent heatwave (HW) episodes in Metropolitan Area Barcelona (AMB) under projected conditions until year 2100. Initially, we identify all HW events AMB over past three decades (1991-2020) and simulate these HWs using high-resolution Weather Research Forecasting model (WRF)...
