Bratislava – Resilient & Sustainable Urban Plan
Challenge
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.
CURRENT SITUATION
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.
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
Solution
BitaGreen’s platform allows users to access climate related data, create simulations and identify strategies to mitigate risk and maximise opportunity. With a combination of interactive maps and AI based analytics, the tool enables the City of Bratislava to produce high-resolution green infrastructure maps. A software and data management interface, the solution allows the City of Bratislava to: Map green assurance solutions at different scale, quantitatively assess costs and benefits of different urban plan scenarios under climate change to create bankable projects for blended investment with high environmental, social and governance score, and monitor performance of green infrastructure.
Results
The BitaGreen solution supported the preparation of the City of Bratislava’s new zoning plan by mapping the risks associated with climate change – drought, heath, torrential rains and other challenges including traffic, noise and air pollution related to the city.
