Demonstration of the application of the Water Use Analysis model (WUAM) on the Saskatchewan portion of the South Saskatchewan River basin focusing on data requirements and preparation, scenario development, and model runs, and on the analysis of the results. The study investigated the water resources impacts of four alternative development scenarios. The scenarios, all assumed to correspond to the year 2000, covered two levels of future water use in Alberta and two levels of irrigation development in Saskatchewan. Only the irrigated area in Saskatchewan was varied; all other irrigation parameters were assumed to remain constant. The system was also simulated under the extreme condition of Alberta's using 50% of the monthly natural streamflow. Irrigation water uses by irrigation area, node, and basin total and consumptive uses from Lake Diefenbaker for irrigation, evaporation, and diversion were analyzed for the various scenarios and their frequencies of occurrence were presented.

This book, first published in 2006, presents an introduction to the methodology of structural equation modeling, illustrates its use, and goes on to argue that it has revolutionary implications for the study of natural systems. A major theme of this book is that we have, up to this point, attempted to study systems primarily using methods (such as the univariate model) that were designed only for considering individual processes. Understanding systems requires the capacity to examine simultaneous influences and responses. Structural equation modeling (SEM) has such capabilities. It also possesses many other traits that add strength to its utility as a means of making scientific progress. In light of the capabilities of SEM, it can be argued that much of ecological theory is currently locked in an immature state that impairs its relevance. It is further argued that the principles of SEM are capable of leading to the development and evaluation of multivariate theories of the sort vitally needed for the conservation of natural systems.

Ecosystem services can be broadly defined as the aspects of ecosystems that provide benefits to people. This book provides guidance on the valuation of ecosystem services, using the case of multifunctional wetlands to illustrate and make recommendations regarding the methods and techniques that can be applied to appraise management options. It provides a review of ecosystem service valuation rationale, including its importance from both a policy and project appraisal perspective, and a useful reference when considering policy and appraisal of ecosystem management options. It shows how legal obligations and other high-level management targets should be taken into account in valuation exercises, thus giving important policy context to the management options. The authors set out what they call an Ecosystem Services Approach to the full appraisal of the role of ecosystem services in the economy and society. Although concentrating on wetlands, the approaches suggested provide an assessment framework that can be applied to other types of ecosystem assets.
