On March 6th, together with the scientists of the KTU Institute of Environmental Engineering, we had an interesting and meaningful discussion with the representatives of the Network of Green Municipalities of Kaunas, Klaipėda, Panevėžys and Alytus cities about the green and social infrastructure of the city. Urbanisation and climate change pose serious challenges in terms of a living environment, quality of life and the equality of society, which are becoming increasingly important issues in urban governance and development. In this conversation, we examined how well-being could be promoted through an innovative approach to the sufficiency of an urbanised environment, which aims to rationally meet the basic needs of society while respecting the planet’s limited resources and responding to climate challenges. The green and social infrastructure of cities can be analysed from an innovative sufficiency perspective, which is one of the most important factors in the development of a climate-friendly environment and resource-efficient society. The data will be analyzed and visualized by GIS software.
