Assessing the cost-effectiveness of the water purification function of wetlands for environmental planning

Nitrogen and dissolved organic carbon (DOC) losses from an artificially drained grassland on organic soils

“…Diffuse nutrient pollution has been found to be a major obstacle to this goal. As nitrate is effectively reduced under wet conditions (Cabezas et al, 2012), re-wetting peatlands has been suggested as a measure to both reduce diffuse pollution originating from degraded peatlands themselves and to clean nutrient-rich water from upstream areas (Davidsson et al, 2002;Trepel, 2010;Vikman et al, 2010). Especially strongly degraded peat seems to have a high denitrification and N retention potential when re-wetted (Cabezas et al, 2012;Davidsson et al, 2002), although other studies have found ongoing mineralisation under these conditions (Olde Venterink et al, 2002).…”

Besides combating diffuse pollution as required by legislative efforts, the monetisation of ecosystem services of peatlands is increasingly coming into the focus of attention (Russi et al, 2013;Trepel, 2010). Both topics need baseline data for drained peatlands against which improvements by re-wetting measures can be evaluated.…”

Evaluating and modeling ecosystem service loss of coal mining: A case study of Mentougou district of Beijing, China

“…There are 8686 hm 2 coal mining areas abandoned in Mentougou district. Using Restoration Cost Method and Shadow-Project Method (Spangenberg and Settele, 2010;Trepel, 2010), if $13164.4 is needed for per hm 2 , then the direct cost of reclamation is about $11.4 million.…”

“…Using Market Value Method and Opportunity-Cost Method (Spangenberg and Settele, 2010;Trepel, 2010), The loss caused by coal solid wastes can be calculated by the following formula:…”

Ecological benefits assessment and spatial modeling of urban ecosystem for controlling urban sprawl in Eastern Beijing, China

“…It is a rigid management model, with the whole area and structure of land strictly controlled, which means that the urban expansion cannot occupy agricultural land, greenbelt and wedge-shaped green spaces; furthermore, the use of some important land resources such as cropland, forested land and wetland that have important ecological service to the city are strictly controlled with regards to future urban development (Trepel, 2010). At the same time, measures such as land consolidation were taken to improve the land use efficiency, and some abandoned lands were used again.…”
