This session is designed to investigate how cities, and more broadly urbanization processes, influence the Main Biogeochemical Cycles. We will focus on the Global Carbon Cycle (GCC) and Nitrogen Cycle (NC). There is a clear influence of urban areas on the GCC associated with anthropogenic emissions of Greenhouse Gases (especially CO2). In terms of nitrogen (N), humans alter N sources by changing atmospheric deposition rates and by accelerating fertilizer and food production. The new emerging phenomenon is the rapid introduction of bio-fuels, which in turn requires intensification of certain crops production, and more fertilizer input. All those processes are directly linked to the areas of densely populated settlements, i.e. cities and Mega-polices.
Important existing research on the topic will be presented in this session and also further discussed, which kind of future developments and data assembling are necessary in order to deal with urbanization, i.e. monitoring and modelling its impact on the Biosphere, under different scenarios.
The emphasis will be given to interdisciplinary approaches and forecasting, considering the problem from various points of view, namely from global and local spatial perspectives and long- and short-term temporal scales, from linear and dynamical behavior point of view; from system's and individual actors' perspective. Measurements and observations should be also considered, including statistical data collection, GIS, satellite databases etc.
