Abstract
This study presents a quantitative approach to support policy decision making for the preservation of riverscapes, taking into account the EC Water Framework Directive (2000/60/EC) and the EC Nitrates Directive (91/676/EEC) concerning the protection of waters against nitrate pollution from agricultural sources. A choice experiment was applied to evaluate the benefits, as perceived by inhabitants, of the implementation of policies aiming to reduce the concentration of nitrates in groundwater, preserve the riverscape by maintaining a minimum water flow and increasing hedges and woods along the Serio River in central northern Italy. Findings suggested that people were particularly concerned about groundwater quality, probably because it is strongly linked to human health. Nevertheless, it was interesting to observe that people expressed a high willingness to pay for actions that affect the riverscape as a whole (such as the minimum water flow maintenance plus reforestation). This is probably due to the close connection between the riverscape and the functions of the river area for recreation, health purposes, and biodiversity preservation.
