4th IPM Symposium
Robert luttik
National Institute of Public Health and the Environment, The Netherlands
Abstract :
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.
