Urban Biogeochemistry


Simon's experience in the management of Urban soils and new methods for improving the longevity of urban vegetation is well known. His many years hard experience in waste to land science is not so well known and this talk will take a Malthusian tour of the biogeochemical flows of nutrients that determine the sustainability of our soils and ultimately our societies. It will identify the major barriers to achievement of such a system focussing on Sydney and propose some radical approaches to developing a sustainable urban ecology. To achieve this a thorough understanding of soil change and a matching or manipulation of land and soil properties to the biogeochemical expectations is required.
