If you are attending the AGU Annual Meeting this year in December, please consider submitting your work to the urban-related sessions below. Deadline for submissions is August 5^th.

Session Title: GC023. Advancing Representation of Urban Processes and Dynamics in Models Across Scales
Section: Global Environmental Change
Submission Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/280093

Description:
Cities are primary drivers of local environmental change and centers of heightened risk, making them critical hubs for adaptation and mitigation. Given the dearth of urban-resolving observations, models are critical for studying urban systems. These models allow us to assess future changes and explore hypothetical scenarios, but remain limited by uncertainties and crude assumptions. This session invites submissions focused on advancing the representation of coupled human-urban-Earth dynamics in models across scales, from large-eddy simulations to mesoscale models to Earth system models. Key topics include: Urban biophysical/biogeochemical processes; Urban vegetation and its spatiotemporal variability; Energy systems, transportation, and associated emissions; Urban morphology and heterogeneity; Urban air pollution and coupled physical-chemical interactions; Dynamic urbanization across regions; and Interactions between socioeconomic processes and physical systems. We welcome research on new parameterizations, benchmarking, and validation techniques, and encourage submissions on process-based, data-driven, machine learning, and hybrid modeling approaches, along with their associated data products.

Session Title: GC124 – Urban Areas and Global Change

Section: Global Environmental Change

Submission Link: https://agu.confex.com/agu/agu26/prelim.cgi/Session/281873

Description:

We live in a rapidly urbanizing world undergoing unprecedented global change. Understanding and adapting to these changes require increasingly diverse methods and interdisciplinary perspectives across natural and social sciences. This session invites empirical, observational, and modeling studies on the biogeochemical, physical, and socio-ecological interactions of urban areas with Earth systems from local to global scales. We welcome perspectives from researchers and practitioners from diverse backgrounds, e.g., from natural and social scientists to engineers and planners. Potential topics include, but are not limited to:

• Urban interactions with the environment (through landscapes, ecosystems, and/or atmosphere) across scales;
• Urban water, energy, and biogeochemical cycles of the past, present, and future;
• Urban-induced changes in spatiotemporal patterns of energy supply and use, transportation, food, water, waste, and/or greenhouse gas emissions;
• Human and population dynamics of urban areas; and
• Influence of socioeconomic, socio-political, and institutional dynamics on urban policy, planning, and management.

Land use is a basic dimension of spatial planning. The most common elements of spatial plans are the documents that refer to the future spatial development of an area. In the last decade, more often than not, when addressing land use, we are referring to land use change. A driver of these changes in cities and towns around the world is often urbanization, which affects the form and function of urban spaces and often results in negative effects; for example, it increases the sealing of the land’s surface, the growth of peri-urban areas, and urban sprawl, and exasperates environmental problems. However, it remains challenging to go beyond merely recognizing, using evidence, the changes that need to be implemented, to instead actively conceptualize the role of planning in directing land use change.

This second edition continues the theme of the original Special Issue titled “Urban Land Use Change and Its Spatial Planning“. This SI aims to collect cutting-edge studies that view changes as characteristic immanent dimensions in land use. Indeed, urbanized areas are known for their changing nature in terms of their dynamic patterns of activities, with varying intensities and concentrations. This implies a shift in research focus, from examining patterns of land use and land cover change in order to center the dynamic interactions within socioeconomic–ecological systems and their resulting impacts on urban planning. This is especially relevant in light of the increasingly common expectations for future urban developments to be open-ended and to consider uncertainty as inherent. This SI aims to collate advancements in research and practice in order to gain insights into the causal connections between planning and land use change. This includes, on one hand, acknowledging change as an inherent constant of urban land use, and, on the other hand, examining aspects that are crucial to the successful implementation of plans that aim to shape and understand future areas.

Dear IAUC community,

We are excited to announce the formal launch of the IAUC Early Career Committee.

Our mission is to strengthen the representation of early-career voices within IAUC. We are dedicated to improving the reach of early-career researchers, planning specialized activities, forming global collaborations and networking opportunities, and supporting the future leaders of the urban climate field.

To achieve these goals, we need to know who you are and how we can best support you.

We have prepared a community survey (https://forms.gle/HLuWYxqrgc2nwGYs8) designed to gather essential information from our early-career members.

By sharing your contact information and research interests through this survey, you will help us:
• Establish a dedicated network to keep you informed about relevant opportunities.
• Curate future events and workshops that align with your specific expertise.
• Identify common research interests to streamline international collaborations within the urban climate community.

Providing your information is the best way to stay connected and ensure your voice is heard as we shape the committee’s first year of programming.

We look forward to working with you to build a vibrant future for the early career community within IAUC.

Best regards,
TC, Xiaoxiong, Ryoga, and Manjul
The Early Career Committee
International Association for Urban Climate (IAUC)
