Calibrating and validating the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) urban cooling model: case studies in France and the United States

Understanding the cooling service provided by vegetation in cities is important to inform urban policy and planning. However, the performance of decision-support tools estimating heat mitigation for urban greening strategies has not been evaluated systemat ...

Carbon flows at neighborhood scale Case study in Geneva, Switzerland

Sophie Lufkin, Ulrich Joseph Jacques Liman, Emmanuel Rey

In a context of political commitment targeting net zero in 2050, controlling carbon flows is an essential operational imperative. The LOCUS methodology (Low carbon urban strategy) makes it possible to establish an exhaustive vision of carbon flows at neigh ...

From roots to canopy: Unraveling the influence of species diversity on tree water relations under warmer and drier climates

Eugénie Isabelle Mas

The worsening of drought events with rising air temperature alters tree water relations causing severe hydraulic impairments and widespread forest mortality. Mixing tree species with contrasting hydraulic traits could reduce forest vulnerability to extreme ...

Regional uniqueness of tree species composition and response to forest loss and climate change

Devis Tuia, Nina Marion Aurélia Van Tiel, Loïc Pellissier

The conservation and restoration of forest ecosystems require detailed knowledge of the native plant compositions. Here, we map global forest tree composition and assess the impacts of historical forest cover loss and climate change on trees. The global oc ...

Spatial Modeling for Building Design Evaluation: from Visual Landscape Quality Assessment to Devaluation Risk Estimation

Adam Robert Swietek

Zoning reform is a crucial tool for cities to adapt to contemporary challenges. However, its implementation remains challenging. Property owners, with a vested interest in the value of their neighborhoods, are sensitive to local developments and the potent ...

Evaluation of 30 urban land surface models in the Urban-PLUMBER project: Phase 1 results

Gabriele Manoli, Matthias Roth

Accurately predicting weather and climate in cities is critical for safeguarding human health and strengthening urban resilience. Multimodel evaluations can lead to model improvements; however, there have been no major intercomparisons of urban-focussed la ...

An analytical approximation of urban heat and dry islands and their impact on convection triggering

Gabriele Manoli, Kai Wang

It is well known that cities increase air and surface temperatures compared to their rural sur-roundings, the so-called urban heat island (UHI) effect. However, the associated changes in at-mospheric humidity (also known as urban dry island, UDI) and conve ...

A mechanistic assessment of urban heat island intensities and drivers across climates

Gabriele Manoli, Ziyan Zhang

The urban heat island effect (UHI) has been widely observed globally, causing climate, health, and energy impacts in cities. The UHI intensities have been found to largely depend on background climate and the properties of the urban fabric. Yet, a complete ...

E-guerrilla 3D participation: Approach, implementation, and usability study

Jens Ingensand, Thibaud Nicolas Chassin

Typical urban participatory approaches engage citizens through lengthy sessions far from the area under transformation by an urban project. Several issues result from these settings of involvement including the mobilization of similar individuals, overwhel ...

Canopy dieback and recovery in Australian native forests following extreme drought

Alice Jacqueline Frédérique Gauthey

In 2019, south-eastern Australia experienced its driest and hottest year on record, resulting in massive canopy dieback events in eucalypt dominated forests. A subsequent period of high precipitation in 2020 provided a rare opportunity to quantify the impa ...

A Simple Mixing-Length Model for Urban Canopy Flows

Fernando Porté Agel, Wai Chi Cheng

Urban canopy models (UCMs) developed based on Prandtl mixing-length theory provide a simple method for predicting urban flows. In the existing models, the Prandtl mixing length and the sectional drag coefficient of buildings are usually assumed to be unifo ...

Spatiotemporal patterns of urbanization during the last four decades in Switzerland and their impacts on urban heat islands

Martí Bosch Padrós

Urbanization is nowadays a global phenomenon which is increasingly concentrating the world's population in cities. In Switzerland, recent decades have seen an unprecedented loss of arable land due to urbanization, which has triggered amendments in the spat ...

Quantifying the impacts of urban morphology on modifying microclimate conditions in extreme weather conditions

Jean-Louis Scartezzini, Kavan Javanroodi, Vahid Moussavi Nik

It is well-known that the morphology of urban areas modifies the variations of climate variables at microscale; known as microclimate conditions. The complexity of urban morphology can lead to undesired wind conditions or excessive air temperature; particu ...

The challenges of studying change in carbon-intensive urban consumption practices: Exploring the dynamics of practice change and of normative considerations in knowledge production

Franziska Meinherz

Problem. To reach international greenhouse gas (GHG) emission targets, the carbon intensity of urban resource and energy consumption must be reduced. Technological innovation alone is not sufficient: The practices that constitute urban household demand for ...

Understanding multimodality through rhythm of life. An empirical evidence from the Swiss case study

Alexis Gumy, Guillaume Simon Joseph Drevon

The car dominance car in the urban transport system may contribute to health and environmental troubles. In recent years, multimodality appears as a central issue for public policies as they try to encourage and develop the modal shift in favour of walking ...

Marteloscopes as training tools for the retention and conservation of habitat trees in forests

Rita Bütler Sauvain

Recently several initiatives on the political and practical level have aimed at promoting forest biodiversity and at halting the loss of species in forest ecosystems. Nevertheless numerous species are still threatened. The main reason for this phenomenon i ...

How building energy models take the local climate into account in an urban context – A review

Dasaraden Mauree

The urban context is often simplified or neglected in Building Energy Models (BEMs) due to the difficulties of taking accurately into account all the heat fluxes emanating from the environment. Oversimplifying the urban context can impact the accuracy of t ...

A digital workflow to quantify regenerative urban design in the context of a changing climate

Pietro Florio, Parag Rastogi, Emanuele Naboni

The regenerative approach to design goes beyond limiting the environmental impact of the built environment and towards the enrichment of the ecosystem, adaptation to climate change, and the improvement of human health. This concept is being applied to buil ...
