Pest risk modelling and mapping for invasive alien species.

Book cover for Pest risk modelling and mapping for invasive alien species.

Description

The International Pest Risk Mapping Workgroup acknowledges that advanced training and a 'tool kit' of software packages are needed to produce pest risk maps that are fully fit for purpose. This book is an initial attempt to address those needs. Invited chapters emphasize specific steps and data requirements to guide users through the development of pest risk models and maps, or components thereof....

Assessing the quality of pest risk models.

The quality of pest risk models depends on their reliability and validity. Reliability refers to the model's trustworthiness and dependability, but the concept is extended to consistency and stability. Approaches to help establish and test consistency are described. Validity assures that models actually portray the expectations or assertions of the model design. Elements of validity can be characterized as face, criterion, content, concurrent and construct validity; and the merits of these elements are presented. In the social sciences, factor analysis has become the favoured method for evaluating reliability and validity. Factor analysis is especially useful when models group variables into indices. This chapter discusses the rationale and interpretation of components of factor analysis and suggests how this analysis might be incorporated into pest risk analysis in the future. Studies in communication reveal that non-technical end users can better understand and trust risk assessments when the assessments contain the best information presented in real language rather than mathematical expressions.
