VAD BESTÄMMER KOSTNADEN FÖR ATT ANLÄGGA VÅTMARKER SOM KVÄVEFÄLLOR? / What are the determinants of costs of creating wetlands as nitrogen sinks?
Wetland creation costs and their determinants are studied by an analysis of detailed dara on wedand creation programmes for causing nitrogen reducdon in two drainage basins in the agricultural district of SW Scania, southernmost Sweden. Estimated cost equations illustrate the importance of excavarion efforts for obtaining good predicrions of creation costs. An analysis of the sensitivity of underlying assumptions is carried out. In addition, the results are compared with those of an earlier study on cost equations. It is also illustrated what the cost estimates imply in terms ofaverage cost per kg reduced nitrogen.
