- Successful implementation of an international nutrient abatement agreement, such as the Baltic Sea Action Plan (BSAP), requires consistent understanding of the baseline nutrient loads, and a perception of acceptable costs and fairness in targeted reductions of these base line loads. This article presents a general framework for identifying the implications of divergence between different nutrient load quantification approaches, with regard to both cost and fairness criteria outcomes, for the international agreement to decrease nutrient loads into the Baltic Sea as presented in the BSAP. The results indicate that even relatively small divergence in the nutrient load quantification translates into relatively large differences in abatement cost for different Baltic Sea countries. A robust result, irrespective of differences in nutrient load assessments, is a conflict between abatement cost effectiveness and fairness, with relatively poor countries facing heavy abatement cost burdens for cost-effective international load abatement.

- Landscapes consisting of several elements, such as wetlands and forests, are multifunctional in nature and produce both market and non-market goods. The need for policies arises from the existence of non-market ecosystem services that are not traded and thereby generally not subject to economic trade-offs in landowner decision making. An efficient incentive scheme for producing both types of goods would require policy designed for each non-market good. However, this may result in high transaction costs, possibly giving second-best solutions a comparative advantage when only one non-market good is regulated. This paper demonstrates that in the Hovran catchment area in mid Sweden, which produces the non-market goods water quality, biodiversity, and scenic beauty, compensation payments for biodiversity production alone provide almost maximum total net value of all market and non-market goods. On the other hand, payments for providing scenic beauty in the form of open landscape may result in lower total net value than no compensation payment at all, due to a negative impact on water quality.

Costs of alien invasive species in Sweden
- 2009
-
Ingår i: Ambio. - : Springer Netherlands. - 0044-7447 .- 1654-7209. ; 38:3

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this paper is to present calculations of total costs of 13 alien invasive species (AIS) in Sweden. All species are subject to control by Swedish public authorities, and estimates for most AIS include either damage cost or actual control cost. The results indicate a total annual cost between approximately 1620 and 5080 million SEK, which correspond to SEK 175 and SEK 565 per capita in Sweden. The estimates are well within the range of similar calculations for other countries, but differ with respect to the composition of costs of different AIS. Whereas costs for the agricultural and forestry sectors dominate in most other studies, the costs of AIS in Sweden are more equally divided among different categories. The results also indicate that the highest costs are attributable to unintentionally introduced AIS and that the most reliable cost estimates are related to human and animal health.

Ecosystem services and regional development : An application to Sweden
- 2009

Ingår i: Ecological Economics. - : Elsevier. - 0921-8009 .- 1873-6106. ; :68, s. 2549-2559

Tidskriftsartikel (refereegranskat)abstract
- This study carries out interregional comparisons of development and sustainable use of natural capital with and without inclusion of non-marketed ecosystem services. A simple dynamic model of an open economy shows that appropriate adjustment of conventional income accounts includes flow and stock components, but excludes explicit entrance of pollution. Calculations are made for Swedish regions and for two types of ecosystem services - pollution sequestration and recreational services - provided by three types of ecosystems: forests, agricultural landscape and wetlands. When comparing the adjusted and non-adjusted regional income accounts it is shown that the two measurements generate significantly different pictures of regional income and growth; regions that are traditionally considered as relatively less growth promoting are shown to hold important sources of wealth from natural capital, while counties that are rich in conventional accounts fall behind when adjusting for values of changes in natural capital.
