To a large extent, economic and environmental parameters describe the state of a society in a particular geographic location at a particular time. This book documents the latest modelling changes in integrated economic-environmental systems to guide policy. Arranged in five sections, it firstly addresses the economic and environmental concepts and modelling approaches that underpin the management of economic-environmental systems, with papers that cover dynamics, social discount rate, valuation of resources and environment, and the roles of technical, behavioural and economy-wide models. Sections two, three and four focus on economic-environmental systems of the domestic economy, while section five addresses the environment in relation to the global economy.
