The research group in Environmental Economics (EnvEco) studies the interactions between economic activities and the water environment by applying various economic methods and tools, such as cost-benefit analysis and hydro-economic models. The cluster uses economic principles and approaches with the aim of supporting the sustainable management of water resources. The main research focus of the group is on the economic modeling and valuation of ecosystem services provided by water resources, the assessment of the social welfare changes associated with water use and allocation, both in terms of quantity and quality, and payments for water services. 

The work of EnvEco relies strongly on interdisciplinary research. The group collaborates closely with scientists from different disciplines at Eawag, including urban water engineers, ecologists, ecotoxicologists, and other natural scientists.

Current research projects

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.
The main aim of the project is to investigate the private provision of global public goods - carbon-neutral products and services - in the context of combating climate change

Completed research projects

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.
This project aims at providing a better insight into the public preferences of the Swiss population for the suggested hydropower expansion.
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.
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.
The main objective is to conduct a cost-effectiveness analysis of a number of different measures for reducing chemical water pollution in the Mönchaltorfer Aa river basin in the Canton of Zurich.
The goal of this research is to assess the value of different environmental amenities, as well as structural house and neighbourhood characteristics.
The project responds to current research gaps on the integration of forest, eco-hydrology and economic sciences to improve decision-making process.
