Metrics for environmental compensation: A comparative analysis of Swedish municipalities

Submitted by Petra Hansson on
EfD Authors:

Environmental compensation (EC) aims at addressing environmental losses due to development projects and involves a need to compare development losses with compensation gains using relevant metrics. A conceptual procedure for computing no net loss is formulated and used as a point of departure for a comparative analysis of metrics used by five Swedish municipalities as a part of their EC implementation in the spatial planning context of detailed development plans.

The value of forest water purification ecosystem services in Costa Rica

Submitted by Petra Hansson on

Highlights

•  Avoiding 1% of catchment's forest loss reduces chemicals use by 0.026% in Costa Rica.

• Improving the turbidity by 1% decreases 0.005% aluminum sulfate needed at the water plants.

• The value of water purification service by forests is USD 9.5 per hectare per year.

• The contribution of forest (per ha) becomes larger as the size of the catchment decreases.

Connectivity at a cost: Economic dynamics of restoring habitat connectivity

Submitted by Vicentia Quartey on
EfD Authors:

Both in the United States and in Europe there is ongoing work on reversing habitat fragmentation and the attendant loss in biodiversity in river systems caused by hydropower and other developments. Fish ladders and other measures are being introduced to restore the connectivity in river systems. In this paper, we set up a theoretical model to investigate what the conditions are for such an investment to be socially profitable.
