technologies, the revitalisation of urban areas (social, economic) and the provision of support to urban development. Territorial strategies implemented within the context of sustainable urban development are sustainable urban strategies (SUS). The SUSs that have been drafted so far pay particular attention to ensuring adherence to the partnership principle. In geographical terms, an SUS covers urban municipalities or urban municipalities with municipalities in the wider city area covered by the SUS. It is expected that at least 8% of the ERDF resources under Regulation (EU) 2021/1058 will be devoted to sustainable urban development. We will use the ITI approach to support green infrastructure projects in the urban environment, as well as sustainable mobility and the efficient use of urban space. In the 2014–2020 period, the ITI approach was recognised as an example of good practice at European level. Implementation in the 2021–2027 period is therefore expected to follow the same path, i.e. ‘bottom-up’ through urban municipalities or their representative body (Association of Municipalities of Slovenia). All urban municipalities in Slovenia will take part, i.e. Ljubljana, Maribor, Ptuj, Murska Sobota, Kranj, Celje, Velenje, Slovenj Gradec, Novo Mesto, Krško, Nova Gorica and Koper. In order to be eligible to receive resources for the co-financing of sustainable urban development operations, an urban municipality must draft (and, where necessary, update) and adopt an SUS. An SUS must outline the economic, environmental, climate, demographic and social challenges and objectives crucial to the sustainable development of the given urban area and relating to the problems of urban development in Slovenia as a whole. 2. Local development (CLLD) In order to develop and implement the common LEADER/CLLD approach, an inter-departmental CLLD 2021–2027 working group, comprising representatives of the managing authorities of the three funds involved in the CLLD, as well as the paying agency and the intermediate body, has been established to locate appropriate synergies between those funds. The interdepartmental CLLD 2021– 2027 working group will act as a coordinating body between the funds and will work actively with the local action groups (LAGs) to monitor and coordinate the implementation of the CLLD approach on the ground. Community-Led Local Development will take place using a ‘bottom-up’ approach running through the LAGs. These groups will be established to carry out complementary measures under the Common Agricultural Policy (EAFRD), cohesion policy (ERDF) and the Common Fisheries Policy (EMFAF). During the 2021–2027 programming period, CLLD will be implemented via the ‘2+1’ system. Under the ERDF and EAFRD, the common LEADER/CLLD approach will be implemented throughout the country. LAG areas will be integrated into a homogeneous geographical and functional whole, with shared local needs and challenges being addressed in joint local development strategies (LDSs). With a view to ensuring continuity of implementation with the 2014–2020 period, the common CLLD approach will be implemented without the main fund. The selection of LAGs and LDSs will be based on common criteria, with the selection being made by the managing authorities of the ERDF and EAFRD. The conditions for setting up the LAGs and the LDSs and the method of implementing the mechanism will be set out in a common national rule, and in the instructions and guidelines issued by the managing authorities. Local development strategies will be approved by the managing authorities of both funds. Local action groups will implement the selected local development strategy in accordance with the tasks set out in Article 33(3) of the Common Provisions Regulation, and prepare and publish public calls for
