The main objective of this research is to conduct a cost-benefit analysis of water quality improvement through upgrading of wastewater treatment plants in Switzerland.
This project aims at providing a better insight into the public preferences of the Swiss population for the suggested hydropower expansion.
The goal of this research is to assess the value of different environmental amenities, as well as structural house and neighbourhood characteristics.
This project aims at closing the knowledge gap on monetary benefits of river rehabilitation by assessing the economic values of improvements in river ecosystem services resulting from river rehabilitation.
A principal objective of the project is to develop a novel theoretical framework that would explain the sources of preference uncertainty in stated choice experiments.
The main objective of this project is to show how economic values of different ecosystem services provided by water resources are spatially distributed across Switzerland.
