The effect of policy measures on agriculture and water quality with respect to nitrogen have been monitored on farms in the sandy regions since the early 1990s. Nitrogen surplus on dairy farms decreased by 100 kg/ha (30%) in the 1991-1999 period due to demonstration projects and the implementation of MINAS, limiting farm gate balance surplus. Nitrogen surplus on arable farms has slightly decrea...

The implementation of the European Union Water Framework Directive (WFD) requires nationally generalizable estimates of the benefits of protecting inland and coastal waters. As an alternative to benefit transfers and meta-analyses, we utilize national recreation inventory data combined with water quality data to model recreation participation and estimate the benefits of water quality improveme...

The use of cost-benefit analysis to evaluate the net welfare payoffs from water projects has now been an established practice for many years. One of the interesting aspects of such cost-benefit studies is that water projects involve an uncertain flow of costs and benefits, arising from the stochastic nature of streamflows. Hence a basic problem for the cost-benefit analyst is that of incorporat...

If the balance between availability and requirement drives the value, then the economic value of water in agriculture should be remarkably higher in water-scarce regions when compared to water-rich regions. Similarly, in water-abundant regions, if the land is scarce, then the incremental return per unit of land should be higher than that in land-rich region that are water-scarce. These hypothes...

Measuring preferences via stated methods remains the only technique to obtain the total economic value of a non-marketed good or service. This study examines if alternative causes of an environmental problem affect individual statements of compensation demanded. Making use of a unique sample drawn from the Netherlands, we find that Hicksian equivalent surplus (ES) is not significantly affected ...
