Publication Abstract

Integrated Assessment of Chemical Pollution Pressures and State Changes

E. Garnacho, P. Kershaw and A. Kenny

The provision of ecosystem integrated advice requires the development of new approaches to allow the integration of pressure and state changes information, as well as include the causal relationships linking state changes and pressures derived from human activities.

Different approaches will be needed to accommodate a very diverse source and nature of data and information distributed at the different levels of a causal relationship. The integrated assessment of such type of data and information requires the use and combination of different techniques and tools and a careful consideration of different ways to overcome different limitations of datasets and information characteristics.

An example on chemical pollution will be presented, to show possible ways to integrate information and data, the use of techniques and tools including stochastic modelling approaches such as the construction of Bayesian Belief Networks to address the new needs emerging from an integrated assessment exercise.
