Biological diversity - or biodiversity - is the term given to
the variety of life on Earth and the natural patterns that it
forms. The biodiversity we see today is the fruit of billions of
years of evolution, shaped by natural processes and, increasingly,
by the influence of humans. It forms the web of life, of which
we are an integral part and upon which we so fully
depend, providing a large number of goods and services that
sustain our lives.
Biodiversity consists of hierarchical levels, encompassing the
range of landscapes and ecosystems found on the planet, the
communities of organisms found within them; the variety of animal,
plant and microorganism species of which these communities consist;
and the genetic differences within each species. All of these
levels are linked by natural (or semi-natural, or human-induced)
processes, from gene-flow at the genetic level through to
successional habitat change at the landscape level.
It is the combination of life forms and their interactions
with each other, and with the rest of the environment, that has
made Earth a uniquely habitable place for humans. However,
biodiversity is threatened by many factors, including habitat
destruction and degradation, pollution, climate change and
introduced species. The loss of biodiversity affects food supplies,
opportunities for tourism and recreation, sources of medicines, and
energy. It also interferes with essential ecological
functions.
The
Convention on Biological Diversity
(
Biodiversity Convention or CBD) was adopted at
the Earth Summit in Rio de Janeiro, Brazil in June 1992, and
entered into force in December 1993. As the first
global treaty to provide a legal framework for biodiversity
conservation, the Convention established three main goals:
- the conservation of biological diversity,
- the sustainable use of its components,
- the fair and equitable sharing of the benefits arising from the
use of genetic resources.
Contracting Parties are required to create and enforce
national strategies and action plans to conserve, protect and
enhance biological diversity. They are also required to undertake
action to implement the thematic work programmes on ecosystems and
a range of cross-cutting issues which have been established to take
forward the provisions of the Convention.
In January 2002 the Cartagena Protocol on Biosafety was
adopted to supplement the provisions of the Convention. This
Agreement, which came into force in September 2003, aims to protect
biodiversity from the potential risks posed by genetically modified
organisms (GMOs). To find out the

those countries that are now Contracting Parties to the Convention
and Contracting Parties to the Biosafety Protocol.
Delivery of CBD within Europe and the
UK
In 2001, this was followed by the production of
Biodiversity
Action Plans for fisheries, agriculture, economic cooperation
and development, and conservation of natural resources. These
sectoral Action Plans define concrete actions and measures to meet
the objectives defined in the strategy, and specify measurable
targets. The European Community has also developed its own
Clearing House
Mechanism to support the implementation of the CBD.
The UK ratified the Convention in June 1994. Since this time
JNCC has provided technical and scientific support to Defra on
issues relating to the CBD, including prominent roles in
National Reporting, the
Global Plant Conservation Strategy ,
the
Ecosystem Approach, the
Global Taxonomy Initiative and JNCC
hosts the
UK Clearing House Mechanism for
biodiversity. Also in 1994 the Government launched the UK
Biodiversity Action Plan (
UK BAP), a national strategy
which identified broad activities for conservation work over the
next 20 years, and established fundamental principles for future
biodiversity conservation. The Department for Environment, Food and
Rural Affairs (Defra) plays host to a Biodiversity Secretariat to
help support the implementation of the UK BAP.
Following the establishment of devolved schemes in 1998, which
included powers over environmental regulation within the UK
countries, separate biodiversity strategies have been developed
in
England,
Northern Ireland Scotland
and
Wales. Obligations arising from Treaties and Conventions
remain the responsibility of the UK government, with the devolved
administrations responsible for implementing obligations that
concern devolved matters. The UK has also identified a number
of national focal points to coordinate the implementation of the
Convention's thematic work programmes and cross-cutting
issues.
The JNCC has developed an interactive website
for the
UK BAP on behalf of the UK
Biodiversity Partnership, to support the work of the Biodiversity
Secretariat.
