Note that, on the contrary to many investigations that have considered direct anthropogenic emission of CO2 (urbanized territories produce ca. 96-98% of it), we are interested in more subtle, and up until the present time, weaker processes associated with the conversion of the surrounding natural ecosystems and landscapes into urban lands. Such conversion inevitably takes place when cities are sprawling and additional "natural" lands are becoming "urbanized". In order to fulfil this task, we first develop a fundamental model of urban space, since the type of land cover within a city makes a difference for a local carbon cycle. Hence, a city is sub-divided by built-up, "green" (parks, etc.) and informal settlements (favelas) fractions. Another aspect is a sub-division of the additio...

Such disturbances in the main driving cycle of the Biosphere (global carbon cycle) and

Cities do not serve just as dynamic centres of activities, jobs and consumption markets, social interactions and cultural expressions, but also carry the weight of the main environmental problems of current times and the near future.

Cities import and concentrate N r in the form of food and fuel, and then disperse it as air and water pollution to other ecosystems covering much larger areas.
