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: ReportsCoral reefs are a critical global resource, both biologically, and in socio-economic terms. Coral reefs are also highly sensitive to climatic influences and appear to number among the most sensitive of all ecosystems to temperature changes, exhibiting the phenomenon known as coral bleaching when stressed by higher than normal sea temperatures.
Resource Type: ReportsThis first analysis of the likely impact of climate change on biodiversity demonstrates the impact on Arctic waterbirds. The Arctic will be the biome most affected by climate change and hence waterbird species, most of which are entirely reliant on Arctic habitats, are particularly vulnerable.
Resource Type: ReportsThis summary report aims to provide the European Commission with an overview of the likely impact of climate change on biodiversity in the European Union and indications as to how the design and implementation of current policy might need to be adapted in order to ensure that the EU respects its commitment to reduce biodiversity loss by 2010 and beyond.
Resource Type: ReportsMost multilateral environmental agreements require Parties to report at regular intervals on the measures they have taken to implement the agreement. National reporting not only aims to inform the Convention bodies such as the secretariat or the Conference of the Parties of an improved implementation of the convention in question but also serves a number of other purposes.
Resource Type: Journal PapersConsideration of predictions for global climate change and the general scientific principles underlying the interaction between vegetation and climate, and examination of likely scenarios for different forest regions.
Resource Type: ReportsIn the past few years, a number of analyses have been undertaken to measure progress towards the 2010 and 2012 CBD targets. This report demonstrates how the measurement of progress is influenced by decisions on which protected areas are included (for instance, whether internationally designated sites, or sites without an assigned IUCN category are included) and which biogeographic datasets used (for instance which mountain dataset is chosen), and highlights the need for standardised methods and datasets.
Resource Type: Journal PapersUsing global scale maps and statistics, we estimate that the conversion of all vulnerable tropical forests to the most valuable other land use at each location could lead to emissions of 670 Gt carbon dioxide (CO2). We then evaluate the role of the global protected area network in preventing emissions from tropical deforestation.
Resource Type: ReportsMoving beyond 2010, successful conservation approaches need to be reinforced and adequately financed. More radical changes are required that recognize biodiversity as a global public good, that integrate biodiversity conservation into policies and decision frameworks for resource production and consumption, and that focus on wider institutional and societal changes to enable more effective implementation of policy.
