Environmental, Economic and Psychophysical benefits of volcanic soil green roofs

Climate change will expose hundreds of millions of people to increasing environmental and social risks so adapting to the effects of climate change, the dramatic mass climate migrations expected in the coming decades, can be addressed with housing strategies suited to the characteristics of the environment. Greening the urban environment is a very important strategy to tackle the problems of urban densification, green infrastructures, like green roofs and green walls, have multiple associated environmental, social and economic benefits that improve buildings performance and the urban environment. Of course, it is a question of economic resources, but from this point of view, the perspective we propose in this study is to highlight the costs-benefits that infrastructures can bring, appropriately studied based on the climate of semi-arid geographical areas, and with the use of volcanic soil substrates. The benefits known from the various studies already conducted are explained here in terms of environmental improvements, with the capture of CO2 by plants; economical, with the energy savings produced by thermal insulation and, finally, with the psychophysical well-being deriving from the relationship between inhabitants, the plant world and nature in general.
