The Bratislava area shows typical metropolitan sprawl, but with a cross-border character. According to recent censuses, the cross-border metropolitan catchment area of Bratislava has a total of more than 13,000 Slovak citizens (7,540 in Austria and 5,465 in Hungary), which is more than the total population of 6 districts within Bratislava, both individually and collectively. Since the vast majority of Slovaks who have moved across the border continue to work, study, use the services and actively contribute to the enrichment of the capital, their needs should be taken into account in the same way as those of the capital’s population. This is also confirmed by the fact that the Slovak residents call Rajka the sixth district of Bratislava, or Little Bratislava.
The spreading of the Slovak capital on the Austrian and Hungarian sides creates a number of concrete problems, especially for those who move out. In case of emergency, they cannot reach the Slovak ambulance service and, for the time being, ambulances cannot cross the border. They may have problems obtaining various permits, administrative procedures and lack of language skills. Social care for the elderly can be a barrier because of the territoriality of social contributions paid during years of work on the other side of the border, etc.
At the same time, relocation also has an impact on the region as a whole. Commuting generates heavy traffic, mainly by private transport, which makes access to the city centre difficult, and the development of environmentally friendly public transport services is essential, as is the development of cycle paths. New housing developments are dramatically reducing the proportion of green areas left undeveloped, degrading the quality of the environment, while the municipalities of small towns with a growing population face a major challenge in maintaining the quality of public services.
The complexity of the problems calls for coordinated cooperation between actors in the three countries, which have different administrative systems, and the development of a governance structure could be the solution. This structure could ensure coordinated planning and development.
