Document Summary
Lecture 03- screening & scoping: major methods and techniques used as tools for eia practice and explain how to select the best methods. Tools for impact identification, interpretation, organization and communication. (i-i-o-c): checklists. Simplest systematic tool; produce comprehensive list; identifies possible consequences; ensures a prescribed list is considered. Advantages: promote thinking about a range of potential issues. Disadvantages: not comprehensive, if they are impractical; too general; subjective: matrices. 2- dimensional checklists; project activities vs potentially affected environmental components; most commonly used tool for impact identification and communication. Magnitude matrices vs. interaction matrices: trends & associations. Assume links and pathways of interaction between individual components of the environment. Identifies pathway of an impact with linkages or network diagrams: spatial analysis. Usually gis (can target area of concern; proposed pipeline routes) Helpful for identifying conflicting land use patterns. Expensive but large amts of data can be analyzed.
