This paper is designed as an introduction to the two papers that follow. It opens with remarks about the nature of systems ecology before discussing its principal technique, systems modelling. This is followed by two simple agricultural examples and a brief discussion of the potential of systems modelling in ecology. More comprehensive treatments can be found in Walters (1971), Patten (1971), a...

Economists increasingly face opportunities to collaborate with ecologists on landscape-level analyses of socioeconomic and ecological processes. Tnis often calls for developing empirical models to project land use change as input into ecological models. Providing ecologists with the land use information they desire can present many challenges regarding data, modeling, and econometrics. This pap...

Economists and ecologists, in general, have offered differing opinions about the seriousness of climate change and the need for rapid reductions in greenhouse gas emissions. Economists have tended to urge caution, focusing on the potential for large-scale cutbacks to upset the economy. Ecologists have tended to focus on the potential for catastrophic losses from climate change, and have urged e...
