In this section, you will find information on some of the main tools used in the evaluation and prediction of environmental impacts.
Prediction and Evaluation Techniques
The prediction of environmental impacts aims to identify environmental/sustainability changes that would result from the project/programme proposal. It compares the likely state of the environment indicators with and without the project/programme. The evaluation of environmental impacts seeks to determine the extent to which the predicted impacts are acceptable: at this stage a judgement is made. Part of the evaluation stage includes identifying ways of minimising impacts.
The following provides a list of prediction and evaluation techniques:
- Assessment Matrix
- Sectoral Checklist
- Adhoc Methods
- Overlay Methods
- Cost benefit Analysis
- Systems analysis and modeling
The above summary of methods is largely based on Biswas and Geping, 1987.
