This handbook is essentially as an introduction to a wide range of methods that can be used to design assessment studies of climate change impacts and related adaptation strategies. It does not serve as a “stand-alone”, step-by-step, or “how to do it” docu- ment. It is not prescriptive nor does it describe only a single method by sector. The intent of providing an overview of methods is to give readers enough information to select the method most appropriate to their situation. However, not enough information is given to apply a method. To carry out an impact assessment, reference must be made to more detailed literature, software and data may need to be obtained from elsewhere, and in many instances individual or small group training and consultation sessions will be required.
