• PIANC Dredging and port construction around coral reefs (2010) »

   One third of the world’s population lives in coastal areas and rapid development of these areas has meant increased construction of coastal infrastruc- ture (e.g. ports, navigation channels, coastal de- fence) and related activities (e.g. land reclamation, beach nourishment), which has inevitably led to conflicting priorities between coral reef conservation and economic growth. The key impacts of these ac- tivities, if not managed, include:
  • Direct loss of coral reef caused by the removal or burial of reefs
  • Lethal or sub-lethal stress to corals caused by elevated turbidity and sedimentation rates
  Dredging and port construction activities potentially affect not only the site itself, but also surrounding ar- eas, through a large number of impact vectors (e.g. turbid plumes, sedimentation, release of contami- nants, bathymetric changes). Effects may be imme- diate or develop over a longer timeframe and may be temporary or permanent in nature, depending on a large number of factors.

  The dataset contained in this map represents the global distribution of warm water coral reefs. It has been created from multiple sources and supercedes the dataset used in the World Atlas of Coral Reefs (2001), although some aspects of this product still originate from that datasource. This global coral reef dataset should be seen an 'interim' global product. It has been compiled from a number of data sources which have been merged together by UNEP-WCMC. The Approximate % coverage of data sources are as follows - Millennium Coral Reefs (Unvalidated) 50% - Millennium Coral Reefs (Validated) 30 % - Other sources 20%.

  The Global Marine Turtle Nesting database provides the distribution of
  marine turtles. Information was obtained from published and unpublished
  literature, and through liaison with turtle fieldworkers. It was intended that
  the database would be of use to a wide audience, including biologists,
  coastal planners and those concerned with emergency response to oil spills.

  The marine turtles database of nesting and feeding sites was developed by
  UNEP-WCMC over a number of years and contains source information from
  1949 to 1993. This dataset is no longer being maintained and must be used
  With caution.

  The seagrass dataset has been compiled by UNEP-WCMC in collaboration with Dr Frederick T. Short, University of New Hampshire, USA to show the global distribution of seagrass species. This dataset has been created from multiple sources and was used in the creation of the "World Atlas of Seagrasses" (2003). This polygon feature dataset is an update of the data used in the Atlas and is a unique data holding about the state of the world's seagrasses. For a complete overview of global seagrass distribution this dataset should be displayed together with the associated point dataset.
