Objectives
Because of the economic and ecological interest which the zone of Haiphong in Vietnam represents, of the potential importance of anthropogenic inputs (nutrients, contaminants, particles, Nhan et al. 1998, 1999, 2005, Ho & Egashira 2000, Viet et al. 2000, Hung & Thiemann 2002, Wosten et al. 2003, Cao 2004), and of the existence of a pole of research and higher education in the area, we are undergoing a multidisciplinary study of the impact of the anthropogenic and hydrological constraints on the operation of this coastal estuarine ecosystem. The focus will be made on the role of the trophic networks, in particular microbial, as micro-organisms actively control the fate and impact of the anthropogenic inputs. Anthropogenic inputs have various origins, and contribute to differing degrees to disturb ecosystems and populations, leading to ecological imbalances and economic impacts. The central objective of this study is to determine the sources, the mechanisms of transport, and the processes of transformation of these contributions, in order to compare their effects on the diversity and functioning of the micro-organisms within the Bach Dang estuary. Our objective is to describe and predict the fate of these elements (integration in the trophic networks, sequestration in the sediments, and/or export to the coastal ecosystem), in order to lead in the long term to an integrated management of the zone in relation with the local actors in research and management. This project thus addresses the typical problems faced by the development of a sustainable management practice in coastal ecosystems, with special focus on the field of pollutants ecodynamics. As well as trying to evaluate the consequences of these pollutants on the microbial communities. References
