Green infrastructure, sustainable development, biodiversity, nature protection - these are just some of the concepts that we encounter in the various discussions and lectures, policies, projects and programs that promote the so - called. "green approach" and natural solutions to our social and economic problems. This thesis explored the concept of the green infrastructure and its application to the actual (real – life) location. Therefore, in the first part of the thesis, problems and goals, work methods and important concepts were set and defined. Through the review of the current, European level documentation, there was a clear cognition of the importance of green infrastructure. The development and possible application of green infrastructure in Croatia was observed through lectures and workshops. The second part of the thesis related to the implementation of the green infrastructure in the actual (real life) location. Defining the green infrastructure as a concept and a mean to improve the human environment, as the European institutions currently do, led to focusing on the possible approach of planning the green infrastructure throughout the Krapina city. The rivers are an important element of green infrastructure. Therefore, the Krapinčica river was recognized and picked within the territorial - administrative boundaries of the Krapina city. By using the method of analysis, the existing infrastructure systems (grey and blue infrastructure) of the Krapina city were presented, with a clear overview (display) of the landscape typology. Aformentioned work methodology and analysis resulted in the development of the guidelines for further development of the Krapina city, with a focus on the physical and thematic linking of the urban and rural parts of the city by way of the green infrastructure concept, with the Krapinščica river as an important element of it.
