UK NEA The most widely used definition of an ecosystem is that adopted by the Convention on Biological Diversity (CBD) and the Millennium Ecosystem Assessment (MA): “A dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit”. Ecosystem services: Key concepts and applications Definition of ecosystem services Ecosystem services are the benefits provided to humans through the transformations of resources (or environmental assets, including land, water, vegetation and atmosphere) into a flow of essential goods and services e.g. clean air, water, and food (Constanza et al. 1997). Ecosystem-based Approaches to Climate Change Adaptation | IUCN Ecosystem-based Approaches to Climate Change Adaptation, or Ecosystem-based Adaptation (EbA) involves a wide range of ecosystem management activities to increase the resilience and reduce the vulnerability of people and the environment to climate change.

The Economics of Ecosystems and Biodiversity (TEEB) is a global initiative focused on “making nature’s values visible”. Its principal objective is to mainstream the values of biodiversity and ecosystem services into decision-making at all levels. It aims to achieve this goal by following a structured approach to valuation that helps

Biodiversity | Convention on Biological Diversity (CBD) Biodiversity in general terms deals with biological and geographical units such as genes, species, ecosystems at different levels of scale up to biogeographic regions.There are many different definitions of biodiversity among which the one used under the Convention on Biological Diversity (CBD) is one of the most frequently cited: Annex 7. The ecosystem approach and adaptive management This focus on structure, processes, functions and interactions is consistent with the definition of ecosystem provided in Article 2 of the CBD: “‘Ecosystem’ means a dynamic complex of plant, animal and micro-organism communities and their non-living environment interacting as a functional unit.” This definition does not specify any
An ecosystem is the smallest unit of a living system which is functionally independent. There is no fixed size of an ecosystem. It can exist at any scale and could, for example, be a complex collection of organisms within the gut of a termite, a grain of soil, a forest or an entire ocean 6.
