Modeling Spatial Sustainability: Spatial Welfare Economics versus Ecological Footprint AgEcon
Grazi, Fabio; van den Bergh, Jeroen C.J.M.; Rietveld, Piet.
A spatial welfare framework for the analysis of the spatial dimensions of sustainability is developed. It incorporates agglomeration effects, interregional trade, negative environmental externalities and various land use categories. The model is used to compare rankings of spatial configurations according to evaluations based on social welfare and ecological footprint indicators. Five spatial configurations are considered for this purpose. The exercise is operationalized with the help of a two-region model of the economy that is in line with the ‘new economic geography’. Various (counter) examples show that the footprint method is not consistent with an approach aimed at maximum social welfare.

The Economic Value of Wetland Conservation and Creation: A Meta-Analysis AgEcon
Ghermandi, Andrea; van den Bergh, Jeroen C.J.M.; Brander, Luke M.; de Groot, Henri L.F.; Nunes, Paulo A.L.D..
The rationale for conservation and creation of wetlands stems from the recognition of both their ecological and economic values. This paper examines the welfare impacts of goods and services provided by wetlands. We collected 385 estimates of the economic value of 181 natural and man-made wetlands from 167 studies worldwide. The resulting database is less biased towards North America than previous reviews of the literature. The relative importance of characteristics of the valuation study, of the wetland site, and of the socio-economic and geographical context is estimated by means of a meta-regression analysis of wetland values. Provision of amenities, flood control and storm buffering, and water quality improvement are the most highly valued wetland...
