“…The research results presented in the paper indicate that the basis for the effectiveness of adaptation activities in public spaces is the inclusion and prioritization of urban nature at every stage of the planning and implementation process. The keys are as follows: a holistic approach to implemented urban nature, in the context of the relationship: the built environment -the natural environment -the residents and their needs, taking into account different spatial scales and different urban areas, carrying out systemic activities and complementing them with spot actions, emphasis on multifunctionality of solutions, supporting community, diversity and activity in public space [52,53], consistency of the city's development documents and policies under development, including spatial planning, architectural policy, and urban design; provision of appropriate formal and informal instruments for the preparation, management, and coordination of the entire process of transformation of public spaces, ensuring implementation of the strategy and achievement of the set goals [54], detailed development of individual stages of implementation of urban nature in public spaces, taking into account the instruments of operational urban planning [55]; inclusion in the process of adapting the city to climate change of the following solutions: legal, organizational, and architectural-urban planning; involvement of public funds for financing individual investments; support for private investments [56], selection of innovative architectural and urban planning solutions, including infrastructure, based on the inventory of resources, analysis of conditions carried out at different spatial scales, and taking into account the guidelines from the provisions of planning and strategic documents; matching them to the character and specificity of the place, as well as visions and quality goals related to the development of the city, the natural system, and the needs of residents [57], inform landowners, users, and developers about the benefits of implementing urban nature in adaptive solutions for public spaces, resulting from the introduction of ecosystem services regarding increased security, increased property and land use value, resource savings, and improved quality of life in the city [58], socialization of planning and implementation processes, ensuring the selection of optimal solutions to meet the needs of residents; providing space for civic initiatives and social activities; cooperation, communication, conducting dialogue and integrated activities of various stakeholders; strengthening the responsibility for urban space and participation of residents, both at the stage of creating strategies and planning, as well as implementation of activities [59], exchange of experience between cities (conferences, workshops, meetings, joint projects, associations, and committees dealing with urban nature) allowing the dissemination of knowledge about instruments for effective planning and implementation of adaptation activities in which urban nature plays a key role [60].…”
