This article discusses a set of principles for policy analysis of environmental problems. The main focus is on integrating economic and ecological analyses through a mathematical modelling framework. The paper starts by developing a general model for

Within the research project, nutrient losses and erosion from agriculture are calculated. Calculations are done with an interdisciplinary modeling system capable of predicting the effect of various policy measures to reduce losses. This paper describ

It is generally accepted that changes in agricultural management during the last decades have had negative effects in the forms of increased erosion and nutrient losses. Even in a country like Norway, which has a low intensity in agricultural product

Validation and calibration of complex models that simulate the soil-plant system are often assumed to depend solely on characteristics of the model. This paper compares the calibration of SOIL by two different users, based on the same set of measured

Excess use of fertilizer-N results in leaching of nitrate, which threatens the environment in various ways. Taxes on nitrogen fertilizers have been suggested as a measure to reduce the nitrogen load to the environment. An economic model for predictin

Large parts of the world are temporarily or permanently covered with snow. In areas with, regular snowmelt in the spring season, meltwater can be the major cause of erosion. Freezing and thawing reduces soil shear strength and infiltration rates can
