“UDCW GIS Tool: Climate Change Impact Assessment for Resilient Cities”

By drafting current city conditions and/or design scenarios in a GIS environment, a range of simulation models can be executed, enabling quantitative and spatial analysis of climate change impacts and the effect of climate-resilient planning and design solutions. In particular, the current version of the models allows the assessment of the health and economic impacts of heat waves and floods, the effect of slow-onset temperature and precipitation variations on energy consumption and production from renewable sources, and the CO2 absorption potential from vegetation cover.

OBJECTIVES
The UDCW GIS Tool offers a comprehensive platform that enables stakeholders to visualize and evaluate the effects of climate change on a city-wide scale. This assessment encompasses various impacts, including heatwaves, flooding, and shifts in energy demand. It allows for the analysis of these impacts under different conditions, including the present conditions, business-as-usual projections, and post-intervention scenarios.

OUTCOMES

• Heat Wave Hazard analysis
• Heat Wave Impact analysis
• Flood Hazard analysis
• Flood Impact analysis
• Energy analysis
• Carbon analysis

TARGET GROUP

• Desision maker
• Technicians
• Civil society
• Other stakeholders

FACILITATORS

Technically qualified experts with a medium level of expertise in GIS.

DATA
COLLECTION
1 to 7 days

Data is collected and organized in a coherent folder structure by the interested entity which usually requires the help of a GIS expert

TRAINING
SESSION
2 to 5 days

Preliminary analysis is performed, like future weather predictions, to establish the baseline of the models. In this phase, data is revised, imported, and organized into their respective layers with their respective attributes to characterize the GIS model

RUN THE
SIMULATION
1 to 5 hours

Different types of simulations are run for the performance of the following analyses:
– Carbon analysis
– Heat Wave Hazard analysis
– Heat Wave Impact analysis
– Flood Hazard Analysis
– Flood Impact analysis
– Energy analysis

RESULTS
VISUALIZATION

All of the simulations generate city-wide GIS in which indicators are shown in a variable side length square grid
