Climate change impacts
Consistent long-term monitoring of air temperatures and other climatic variables in Bratislava have shown an increase of number of tropical days and nights and changes in air humidity, etc. Due to recurrent flooding of the Danube River, the city is protected against 1,000 and 100-year floods with built and mobile flood protection measures.
Main motivation for taking adaptation action
As outlined in the Strategy for adaptation in Bratislava (2014) the main goal is to cooperate with external partners and its citizens in implementing the necessary adaptation and mitigation measures in order to eliminate and minimise the negative effects of climate change and provide an adequate quality of living and natural environments, protection of human health and property, and provide long-term, suitable conditions for a high quality life of its citizens and visitors.

Summary of the strategy/plan
Bratislava's adaptation strategy is an important milestone on Bratislava´s adaptation journey. It provides a general overview of the climate scenarios and expected climate change impacts. The rest of the document consists of a catalogue of green, grey, and soft adaptation measures. Altogether 82 measures were identified across 8 sectors. The short and mid-term measures are to be elaborated in the forthcoming Action plan for adaptation to climate change in Bratislava 2017-2020.
To develop its adaptation plan and strategy, Bratislava cooperates with partners from research institutions such as the Faculty of Natural Sciences of Comenius Universities, Slovak Academy of Sciences, and the Slovak Hydrometeorological Institute. On international level, the city cooperates with international organisations within the H2020 RESIN Project (http://www.resin-cities.eu/) where the activities focus on co-creating a more resilient city.
Additional information on adaptation responses
In addition to Bratislava's Adaptation Strategy and forthcoming Action Plan, the city also has an Action plan for sustainable energetic development, which was approved on 30 January 2014. It contains measures to reduce CO2 emissions in Bratislava in sectors such as public and individual transport and increase the energy efficiency of buildings and their operation. The city also has an Action plan for development of pedestrian and bicycle transport from 2016, which is short term action plan on alternative means of individual transport.
Planned adaptation actions
The Strategy on adaptation and the forthcoming Action plan for adaptation to climate change in Bratislava 2017-2020 focus on the following goals: assessing the vulnerability of the city to most relevant climate change hazards, mainstreaming adaptation planning into policies, being a climate neutral city, supporting awareness raising and partnerships in climate change adaptation, and providing a framework for monitoring and evaluation of the adaptation process.
Good practice / spotlight item
Reducing the impact of summer heat waves
In order to reduce the impact of summer heat waves, Bratislava conducted an assessment of temperatures and green infrastructure throughout the city. The analysis revealed vast differences between temperatures, which could be as low as 29 degrees Celcius in the floodplain and at the same time, 42 in the area shopping area. Since green infrastructure is one factor that can reduce the intensity of summer heat waves, Bratislava intends to increase the amount of green infrastructure throughout the city, taking into account the sensitivity and adaptive capacity of the local population.
Pilot projects in sustainable rainwater management
Bratislava has received funding from “EEA Grants and Norway Grants” for an urban climate adaptation project. The project entitled ‘Bratislava is preparing for climate change – the pilot application of the measures in the field of the sustainable rainwater management in urban area’ implements measures to enhance the resilience of Bratislava city to the adverse impacts of climate change, in particular intense rainfall and heat. These measures include tree planting, green roofs and rainwater retention facilities. The benefits are primarily for the most vulnerable inhabitants of Bratislava: elderly people and children. The € 3.3 million project is for 85% funded by EEA Grants. The remaining 15% comes from the city office and two participating city districts. The main project partners are the city of Bratislava Office, the city districts of Nové Mesto and Petržalka, and the Norwegian partner COWI. But also other stakeholders and knowledge partners like the Comenius University or NGOs, are involved to secure exchange of knowledge and coordination of measure. More information can be found online here.
Bratislava has also launched a sustainable water management grant scheme (subsidy) for household owners and private sector – in 2016 Bratislava City launched a subsidy program supporting implementation of sustainable rain water measures (establishment of SUDs, rain gardens, infiltration trenches, green roofs, reservoirs, etc.). Since summer 2016 there have been 16 applicants, 13 of which have been granted the subsidy. It covers 50% of the estimated measure cost or up to 1000 EURO per application.
