Climate adaption and shrinking cities

Beside that there is a strong process of urbanization globally, we can also witness depriving regions, specifically areas with vernacular architecture but not developing as other contemporary regions of the city. Usually a shift in industry, economy, or big political changes, and centralization also lead to a despair of a region, causing a loss of jobs, and population.
Working with a range of small village municipalities (with a population between 30 and 900 inhabitants) in Hungary, we also realized the rich heritage of high-quality vernacular architecture. Vernacular architecture has been discussed and examined to be more resilient to climate change due to the usage of natural materials as clay and wood. The question arises: is it possible to build a future and strengthen resiliency to climate change to these regions based on their vernacular building stock? Similarly, Indian cities have always developed around core heritage area and further expanded around due to urbanisation need in contrasting contemporary materials and elements of architecture, leaving the core areas in deprivation.
Depriving regions or old city areas can be characterized by elderly, therefore non-resilient population, municipalities face economic difficulties, social deviancy, a lack of professionals in spatial planning, concluding to a high exposure and low resilience in terms of institutional system and population as well, causing a low ability to adapt to climate change as well.
This study examines the question in detail, by conducting investigating local climate data, building stock, materials, environment components, social indices etc and will also take into consideration possible ways of escaping forward. The research is conducted in cities of heritage importance in Hungary and India and analysed for their adapting capabilities to climate change.
