4th IPM Symposium
National Institute of Public Health and the Environment, The Netherlands
Over the last 10 years there has been a joint effort by government, industry and farmers to reduce the use and emission of pesticides in the Netherlands. Instead of monitoring, the environmental quality, modelling techniques have been used to measure the improvements. The developed tools use information on sales data, agricultural knowledge, emission characteristics physico-chemical properties and geographical characteristics for the Netherlands. Environmental indicators have been developed for the aquatic ecosystem, the terrestrial ecosystem and for groundwater.
These Dutch indicators are based on the risk quotient of the predicted environmental concentration (PEC) divided by the toxicity and on a scaling factor that depends on the number of hectares treated. But other types of indicators are also possible and that is what is happening in the world. The indicators adopted by several countries are not based on the same principles and it is therefore difficult to compare outcomes from one country with those from an other country. This is the reason why the OECD has started a working group with the task to compare different indicator models to see what results they produce and how user-friendly and transparent they are. In this presentation I will show some results of the Dutch approach and in addition I will compare some of the European indicators to show what the differences are.
