Let’s define….


Biodiversity is the variation of life forms within a given ecosystem, biome, or on the entire Earth.

Ecosystem refers to the combined physical and biological components of an environment and humans

Ecosystem services are the benefits that people obtain from ecosystems – the goods and services of nature

A Framework for Understanding – The Millennium Ecosystem Assessment (MA)

Shows the importance of ecosystem services for human well-being and business development.

The Assessment was a four-year international audit of ecosystems

Involved more than 1,360 scientists, economists, business professionals, and other experts from 95 countries

Its findings provide the first state-of-the-art scientific evaluation of the condition and trends in the world‘s ecosystems and the services they provide

What is the MA?

Group Exercise 1Group Exercise 11. Identify

an important biodiversity and ecosystem service based industry in your country (e.g. agriculture, forestry, mining/extractives)

the 3-5 most important ecosystem services that are affected by this industry

those ecosystem services values that are not well reflected in markets and those that are not

appropriate measures and indicators of status of these ecosystem services

TEEB Training

Review the MA list of ecosystem services

- which ones have a significant international dimension?

- Rank the top 3 in order of importance for attention from international policy-makers
