Monitoring catchment scale agricultural pollution in Norway: policy instruments, implementation of mitigation methods and trends in nutrient and sediment losses
Abstract Agricultural management and losses of nitrogen (N), phosphorus (P) and suspended sediments (SS) from eight small (85–2830 ha) catchments in Norway were analysed. The catchments representExpand

Trends in nutrient concentrations in Latvian rivers and the response to the dramatic change in agriculture
In recent years, the use of fertilisers in the Baltic countries (Estonia, Latvia, and Lithuania) has decreased at an unprecedented rate. The import of mineral fertilisers and feed stuff became almostExpand

Effects of large-scale changes in emissions on nutrient concentrations in Estonian rivers in the Lake Peipsi drainage basin
Abstract The fall of the Iron Curtain resulted in dramatic changes in Eastern Europe, including substantial reductions in the use of fertilisers and livestock production, as well as a marked decreaseExpand

Integrated tool for risk assessment in agricultural management of soil erosion and losses of phosphorus and nitrogen.
In recent years, increased attention has been focused on models for risk assessment of source areas in agricultural landscapes. Among the simplest of such models are index tools, which have beenExpand

Time scales of nutrient losses from land to sea - a European perspective.
Abstract Empirical data regarding the time scales of nutrient losses from soil to water and land to sea were reviewed. The appearance of strongly elevated concentrations of nitrogen and phosphorus inExpand

Regional variations in diffuse nitrogen losses from agriculture in the Nordic and Baltic regions
Abstract. This paper describes nitrogen losses from, and the characteristics of, 35 selected catchments (12 to 2000 ha) in the Nordic and Baltic countries. Average annual losses of N in 1994–1997Expand

Reduction of Baltic Sea Nutrient Inputs and Allocation of Abatement Costs Within the Baltic Sea Catchment
The Baltic Sea Action Plan (BSAP) requires tools to simulate effects and costs of various nutrient abatement strategies. Hierarchically connected databases and models of the entire catchment haveExpand

Impact of sampling frequency on mean concentrations and estimated loads of suspended sediment in a Norwegian river: implications for water management.
Reliable estimates of mean concentrations and loads of pollutants in rivers have become increasingly important for management purposes, particularly with the implementation of the European UnionExpand

Identifying Hot Spots of Agricultural Nitrogen Loss Within the Baltic Sea Drainage Basin
Agricultural management practices are among the major drivers of agricultural nitrogen (N) loss. Legislation and management incentives for measures to mitigate N loss should eventually be carried outExpand
