Biodiversity underpins ecosystems and an ecosystems approach provides a framework for looking at whole ecosystems in decision-making, and for valuing the ecosystem services they provide, to ensure that society can maintain a healthy and resilient natural environment now and for future generations.
The Convention on Biological Diversity (CBD) defines the ecosystem approach as “A strategy for the integrated management of land, water and living resources that promotes conservation and sustainable use in an equitable way”. In general terms, an ecosystem approach is designed to deliver biodiversity action at a larger scale than a single species or habitat and takes account of the needs of people at the same time. To complement the definition, the CBD define 12 complimentary and interlinked Ecosystem Approach principles
The CBD has also proposed Operational Guidance for application of the ecosystem approach focused around 5 key points.
A number of EU environmental directives are shaped to take an ecosystem approach:
The UK is a signatory to the Party to the Convention on Biological Diversity and the approach across the four countries is focused towards promoting and applying an ecosystems approach. The approach is being taken forward in partnership with public bodies and non-governmental organisations.
The Ecosystems Knowledge Network contains resources and information that help explain the ecosystems approach and how it is adopted in practice.
Case Studies in Wales
A range of case studies which demonstrate projects adopting an ecosystems approach in Wales.
Pont is an organisation that encourages and facilitates grazing for the benefit of the wildlife, landscape and cultural heritage of Wales. Pont projects include large-scale habitat restoration in Anglesey, Carmarthenshire and Bridgend.
RSPB Futurescapes Projects Working in partnership with many organisations, the RSPB Futurescapes initiative is aiming to make UK landscapes more wildlife-friendly and habitats less fragmented.
Wildlife Trusts Living Landscapes Projects
Living Landscape and is a new way of thinking championed by the Wildlife Trusts on how we manage land to do more for wildlife, people and the economy.
Case studies in England
Natural England projects demonstrating how the ecosystem approach and ecosystem services relate to land and water management in the landscape.
Parrett Catchment, Somerset
The Management of the Parrett Catchment, Somerset is a case study which shows how specific tools and methodologies were developed to manage the Parrett river catchment.
The UK National Ecosystem Assessment is the first analysis of the UK’s natural environment in terms of the benefits it provides to society and continuing economic prosperity. It is based around the processes that link human societies and their well-being with the environment and emphasises the role of ecosystems in providing services that bring well-being to people.
There is a specific chapter relating to Wales " Status and changes in ecosystems and their services to society: Wales" UK NEA has come at the right time to provide an overview of the evidence base for the Natural Environment Framework policy and governance initiative in Wales.
The six key findings of the assessment are:
The TEEB study is a major international initiative to draw attention to the global economic benefits of biodiversity, to highlight the growing costs of biodiversity loss and ecosystem degradation, and to draw together expertise from the fields of science, economics and policy to enable practical actions moving forward.
Wales Biodiversity Partnership is working to meet these challenges - to secure a future for biodiversity and for future generations
