The 2008 Intermediate Input-Output Meeting focuses especially on managing the environment. We believe that there is some worldwide concern about crucial topics such as climate change; environmentally extended worldwide input-output modelling and databases; physical methods and tools regarding environmental economic impacts; analysis of disasters; related economic, environmental and energy modelling at a global level; environmental effects on changes in life styles and consumption preferences; environment and trade related issues; and the use of renewable or non-renewable natural resources, among others. Thus, since input-output techniques and input-output based models are increasingly playing a more important role in addressing key questions regarding these topics, the discussions will hopefully contribute to a better knowledge and a better management of future environmental challenges for human beings. The applications may be then at a global, national, regional or local level, and in terms of commodities, industries and/or activities. From the Local Organization Committee, we wish you a fruitful and productive attendance at this international meeting hosted by the Pablo de Olavide University and we are looking forward to welcoming you all next summer.
