A glossary of definitions for terms relating to biodiversity, ecosystems services and conservation.
All definitions are referenced, where possible preference has been given to internationally recognised definitions (for example those defined by international conventions or agreements). The terms have been chosen to support understanding of biodiversity and conservation issues, and terms relating to biodiversity loss are complemented by those relating to conservation responses supported by international conservation organisations, governments, scientists and business sectors.
More detailed explanations are provided for a number of key terms, to provide further background information.
The terms can be filtered by category to aid in the navigation of the many definitions.
Convention on the Protection of the Black Sea Against Pollution (Bucharest Convention)
A UNEP Regional Seas Convention for the Black Sea. It is the basic framework of agreement and three specific Protocols, which are: the control of land-based sources of pollution; dumping of waste; and joint action in the case of accidents (such as oil spills). It was signed in Bucharest in April 1992, and ratified by all six legislative assemblies of the Black Sea countries in the beginning of 1994.
Its biodiversity relevance stems from the highly detrimental effect that pollution can have on marine organisms, therefore by preventing the pollution of the sea the Convention contributes towards the maintenance of marine biodiversity. It also includes a draft Protocol on Biodiversity and Marine Living Resources.2
