A practical guide for coastal resource managers to reduce damage from Catchment areas based on best practice case studies
Resource Type: Tools / ApplicationsSeagrasses are unique as they are the only marine flowering plants. Seagrass beds form complex physical structures and are a highly productive ecosystem. This enables them to support a considerable biomass and diversity of associated species. For the first time the World Atlas of Seagrasses summarises the opinion and science of the world's leading experts on the global status of the ecosystem.
The Atlas is a collaboration of more than 50 authors from 25 nations. Fully illustrated, the Atlas contains the first global and regional maps of seagrass distribution and a wealth of information on key issues concerning this 'forgotten' ecosystem.
Resource Type: Books 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.
In 2008, the Convention on Biological Diversity adopted scientific criteria for identifying ecologically or biologically significant marine areas in need of protection on the open oceans and deep seas.
While much scientific discovery lies ahead, available information and current and emerging methodologies already allow us to begin identifying oceanic features that are likely of particular ecological or biological importance.
The World Mangrove Atlas is the first significant attempt to provide an overview of the distribution of mangroves worldwide. Mapped data were gathered from a wide range of sources and synthesised into a series of regional maps. Related texts describe the species, areal extent and other summary information on the currently known status of mangroves in each country. Produced in association with the International Society for Mangrove Ecosystems (ISME) and the International Tropical Timber Organization (ITTO), The World Mangrove Atlas presents a baseline inventory of mangroves at the end of the twentieth century.
Resource Type: BooksThe World Atlas of Coral Reefs is an invaluable resource to be enjoyed and used by a broad audience ranging from global travellers to scientists, including all those with an interest in the natural history of coral reefs, resource managers, travel organisations and university students. The book also caters to the needs of amateur divers and boat owners as a key information resource.
Resource Type: BooksThe areas of the ocean that lie beyond national jurisdiction limits, also called the high seas, are vulnerable to human activities and currently underrepresented when compared to terrestrial and nearshore1 marine environments under protection. Thus, there is a growing movement among the conservation community to increase measures, such as marine protected areas, that can ensure protection of the largely undiscovered but important biodiversity of the high seas.
Resource Type: ReportsThis report presents comprehensive and up-to-date information and data on marine cold-water coral reefs from around the world. Cold Water Coral Reefs: Out of Sight - No Longer Out of Mind aims to provide policy makers with the information required to take concerted action in the conservation, protection and sustainable management of these beautiful, largely unexplored and fragile coral reefs.
The World's oceans play a crucial role for life on the planet. Healthy seas and the services they provide are key to the future development of mankind. Our seas are highly dynamic, structured and complex systems. The seafloor consists of vast shelves and plains with huge mountains, canyons and trenches which dwarf similar structures on land. Ocean currents transport water masses many times larger than all rivers on Earth combined.
In this report, the locations of the most productive fishing grounds in the World - from shallow, coastal waters to the deep and high seas - are compared to projected scenarios of climate change, ocean acidification, coral bleaching, intensity of fisheries, land-based pollution, increase of invasive species infestations and growth in coastal development.
Resource Type: ReportsHotspot Ecosystem Research on the Margins of European Seas (HERMES) was one of the 40 most successful projects under the EU's 6th Framework Programme for Research and Technological Development. Following completion of the project in March 2009, The HERMES Story is published jointly by HERMES and UNEP to inform policy and decision makers from around the world about the lessons learned and the amazing new insights into deep-sea biodiversity, structure, function and dynamics discovered under HERMES. The HERMES Story highlights the need for concerted action to protect the deep sea against the increasing pressures, threats and impacts from human activities and climate change, and provides inspiration for the development of similar deep-sea research projects in other regions.
