Local context

Each year Bratislava feels the effects of climate change more strongly. Increasing pollution levels in the city reflect the rising number of cars – a number which has doubled over the past 20 years. Compounding this trend towards use of private cars is the COVID-19 pandemic, causing a decrease in public transport usage among residents.

The city is in the process of preparing a new zoning plan that will reflect the effects of climate change. The plan will include green and blue infrastructure and adaptations to mitigate increased temperatures and flash floods and minimise the effects of increased car traffic. An objective of this new zoning plan is to create more liveable and comfortable public spaces by implementing urban interventions that are attractive and encourage active mobility.

To achieve this objective, it is necessary for the city to understand the specific climate change impacts on areas of the city, identify the key areas for improvement, and plan appropriate public realm interventions.

Solution objectives

The solution should meet at least one of the following objectives:

• An eco-index solution that models and predicts climate change impacts using available data sources such as greenery, built environment (current zoning plan), climate data (temperature, precipitation), satellite images (for example Copernicus), and their impact on the specific area.

• A web application solution that allows visualisation of the modelling results (heat islands), potential solutions (green-blue infrastructure) and ability to change input criteria.

---

Solution impacts

The solution should target at least one of the following impacts:

• Improvements to the city-wide zoning and urban plan 
• Identified areas to claim for active mobility  
• Identified the top 20 most important zones for public realm interventions (eg. green-blue infrastructure)
