Migracije i urbana transformacija Zagreba: Integracija, digitalizacija i održivost kroz koncepte pametnog grada, grada budućnosti i grada dolaska

This paper analyzes the urban transformational experience of the City of Zagreb by applying three contemporary urban development concepts: smart city, future city, and arrival city.The aim of the paper is to provide an overview of the contemporary literature dealing with these concepts, with a special focus on their connection to migration processes in Croatia and the City of Zagreb, local integration capacities, and the transformation of urban communities.Through a comparative analysis of the city's strategic and planning documents, such as the City of Zagreb Development Strategy 2021-2027, Zagreb Smart City Action Plan, Action Plan for Sustainability and Energy Efficiency, as well as relevant European reports like Horizon 2020 and Open Data Maturity Report, the paper aims to assess the extent of impact that digital and sustainable policies have on the urban transformation process in Zagreb.The analysis of the city's strategic and operational documents reveals that Zagreb is making ambitious, yet still fragmented, steps toward digital and sustainable urban transition.At the same time, the paper confirms the city's historical and current role as a key Croatian arrival city, given its increasing role in the reception and integration of immigrants.The paper shows how digital technologies, local integration policies, and migrant entrepreneurship are driving the city's contemporary urban development.However, limitations in implementation, institutional capacities, and the inclusion of marginalized groups in participatory processes are also evident.
