Landslides are a severe problem during the rainy season in many mountainous regions in Asia where forests have been cut so that mountain slopes are destabilized. In this study we analyze the extent and causes of landslides in a mountainous area in Northern Vietnam as viewed from the perspective...

In this paper we show how citizen expert groups can be used to improve the design of contingent valuation surveys. The concept of citizen expert groups combines the various advantages of focus groups and of participatory approaches like citizen juries and the market stall method. Using an...

Though contingent valuation is the dominant technique for the valuation of public projects, especially in the environmental sector, the high costs of contingent valuation surveys prevent the use of this method for the assessment of relatively small projects. The reason for this cost problem is...

Researchers using questionnaires to elicit preferences must decide whether to include response options that allow respondents to express "no opinion." Using a split-sample design, we explore the implications of alternative answer formats including and not including no-opinion responses in an...

In many societies, social norms create common property rights in natural resources, limiting incentives for private investment. This paper uses a randomized evaluation in Kenya to measure the health impacts of investments to improve source water quality through spring protection, estimate the...

This paper examines the role of participation as a tool for improving individuals’ perceptions and environmental values using a test-retest experiment conducted in south-eastern Nigeria. Two identical contingent valuation experiments were interspersed by participatory workshops designed to...

The ecosystem services provided by coastal and nearshore marine systems contribute significantly to human welfare. However, studies that document values of these services are widely scattered in the peer-reviewed literature. We collected 39 contingent valuation papers with 120 observations to...

The yellow floating heart is a water weed causing nuisance problems in Swedish watercourses. An economic analysis of this is required where various management options are considered. The benefits of a management program are to a large extent recreational. Using a choice experiment we estimate...

Climate change scenarios predict an increase of extreme rain events, which will increase the risk of wastewater flooding and of missing legal water quality targets. This study elicits the willingness to pay to reduce ecological and health risks from combined sewer overflows (CSOs) in rivers and...
