Comparison of GeoPEARL with the single scenario approach in pesticide registration
Several countries use one or a few scenarios to evaluate the leaching of pesticides. This, however, can be too strict for some substances while being too lenient for others, because of the wide ranges…
Nationwide assessments of non-point source pollution with field-scale developed models: the pesticide case
The use of nationwide models of non-point source pollutants in soils is now common practice. Most of these models have originally been developed at the field-scale. An integrated approach (a ‘research…
Methodological approach for evaluating first tier PEC groundwater scenarios supporting the prediction of environmental concentrations of pesticides at the European scale
Within the framework of the harmonised registration of plant protection products (PPPs) at the EU-scale, environmental fate models are nowadays combined with a series of scenarios to predict the…
Modelling and Mapping of Critical Thresholds in Europe
This report informs parties under the Convention on Long-range Transboundary Air Pollution (CLRTAP) and its network of National Focal Centres on the recent update of the European critical loads…
Issues in international climate policy: theory and policy
Climate change is currently at the centre of scientific and political debate, and the need for well-designed international climate policies is widely recognized. Despite this, the complexity of both…
Options for international climate policies: towards an effective regime
The authors contribute to the many discussions on international climate policy and provide an in-depth analysis of the main characteristics of the problem of climate change. They highlight the various…
Are we sure? Some thoughts about uncertainty treatment in integrated assessment
‘Are we sure?’ ‘Are we right?’ ‘Do we feel confident?’ These questions summarise the feeling of uncertainty that is always nagging at our conscience whenever a policy decision is going to be based on…
Value of decomposition figures in emission reduction policy analysis at international level - Report of a traineeship at RIVM
Decomposition analysis is a method for dis-entangling the different key-factors that determine temporal changes in emission levels. It is a 'top-down' method starting from general available…
Present state and future prospects for groundwater ecosystems
Ecological and socioeconomic aspects of subterranean hydrosystems have changed during the past 40–50 years. The major environmental pressures (mainly anthropogenic ones) impact the quantity and…
