The city of Trenčín as the target area of implementation of the project belongs to ecologically balanced cities, with a number of city parks – “green lungs” of the city, which create a pleasant environment for the population, but due to the ongoing climate change it is more necessary, with a professional approach to reconstruct their growing structures for future generations. The aim of this project “Green Lung of the City – Revitalisation of Park M. R. Štefánik, Trenčín” is to protect and support ecosystem services provided by the city park as an element of green infrastructure contributing to the improvement of the quality of life in the urban environment and the adaptability of the territory of Trenčín to climate change. The aim of the project is to be achieved by reconstructing the growing structures of the part of the green lungs of Trenčín – by revitalising the green park M.R. Štefánik providing biodiversity environment and enabling ecosystems to operate and provide services by connecting urban, suburban and rural areas The result of the project will be to increase the share of green infrastructure in the overall area of Trenčín by building 1 element of green infrastructure – green park providing biodiversity environment and enabling ecosystems to operate and provide services by connecting urban, suburban and rural areas and 33.582 m² of restored open space in the city area – Trenčín.  The physical outputs of the main activity of the project should help to increase the share of green infrastructure in the overall area of Trenčín and thus contribute to increasing the resilience of the settlement environment to the negative impacts of climate change (e.g. by reducing the effect of urban temperature islands, etc.), increasing the resilience of settlements to the expected challenges of further development of society (through nature and landscape protection, etc.).  The project is thus fully in line with the IROP intervention strategy, and by implementing the project we will contribute to the achievement of strategic urban, regional, national and European objectives in the field of improving environmental aspects in cities and urban areas by building elements of green infrastructure and adapting the urbanised environment to climate change, as well as by introducing system elements to reduce air pollution and noise in order to improve the quality of life for residents of Trenčín. The project will have a positive impact on the quality of the environment, as it is another step in the implementation of a set of adaptation measures, the implementation of which will strengthen the capacity of the territory of the city of Trenčín conceptually to face changes and risks arising from climate change.
