An initial economic evaluation of water quality improvements in the Randers Fjord, Denmark.

چکیده
Eutrophication of estuarine and coastal waters has only been recognised as a potential problem since the early 1980s. This problem is being addressed by the European Union through the implementation of recent water quality legislation, which also calls for an economic analysis relating to its implementation. This paper examines the benefits and costs of reduced eutrophication of the Randers Fjord in Denmark, with a primary focus on assessing individual preferences for water quality improvements, using a contingent valuation survey approach. Initial findings of the survey are presented that offer support for funding an action plan to improve the ecological status of the Randers Fjord, as required by the Water Framework Directive. The paper highlights the considerable costs required to abate nutrient emissions into the Fjord, but identifies a need for greater cost evidence at the catchment level.

The metabolic status, the difference between organic matter production and consumption of an estuary (Randers Fjord, Denmark) has been assessed based on 2 field cruises in April and August 2001 and a number of approaches: (1) the oxygen (O2) incubation method, (2) dissolved inorganic carbon (DIC) budgets, (3) the response surface difference (RSD) method based on diel O2 changes and (4) land–oce...
متن کاملGas transfer velocities of CO2 in three European estuaries (Randers Fjord, Scheldt, and Thames). Limnol. Oceanogr., 49(5), 2004,
We measured the flux of CO2 across the air–water interface using the floating chamber method in three European estuaries with contrasting physical characteristics (Randers Fjord, Scheldt, and Thames). We computed the gas transfer velocity of CO2 (k) from the CO2 flux and concomitant measurements of the air–water gradient of the partial pressure of CO2 (pCO2). There was a significant linear rela...

Abstract Land salinization is a major obstacle to the sustainable development of agriculture in arid regions. The demand for food, fiber, fuel and fresh water has increased in the recent decades, particularly in developing nations, due to alarming rise in population. As fresh water resources and productive lands for crop production are limited, new strategies for the sustainable utilization of ...
