NOMIRACLE, ISPRA 8-9 June Pesticide consumption HerbicidesInsecticides FungicidesTotal pesticides Source: EUROSTAT

NOMIRACLE, ISPRA 8-9 June Available pesticide data 1.EUROSTAT - only chemical classes (TAPAS, Technical Action Plans for Agricultural Statistics are trying to improve pesticide data) - All MS have at least sales data - some MS potentially have good use data not yet compiled - problems of confidentiality 2.Country specific sales data on active ingredients (Most north European countries) - problems of confidentiality - by adding expert judgement of pesticides distribution between crops (like in Denmark) an increased potential for distribution is possible - does only partly take into account actual farming praxis 3.Country specific consumption data (UK, Sweden and the Netherlands) - Questionnaires to farmers (FADN data) - limited data transferring to other countries (cluster analysis) - should be representative for all pesticides, crops and climatic zones - is the data reliable? - up-scaling to national sales data? 4.Data from chemical companies and NGOs (PAN- Pesticide Action Network) - not complete

NOMIRACLE, ISPRA 8-9 June Agricultural praxis The need/use of pesticides depends on: Crop parameters: Mono culture increase the pesticide input in general High nitrogen allowances increase the need for growth regulators and insecticides High value crops have higher pesticide input rates Climatic conditions: Warm climate increase the need for insecticides (limited need for insecticides in the Nordic countries) Humid climates increase the need for herbicides and fungicides Availability of pesticides: Few restrictions increase the use of soil disinfectants instead use of crop rotation Few restrictions gives space for use of very toxic and broad spectrum pesticides Education and awareness of the farmers: Pesticide support systems may reduce pesticide use

NOMIRACLE, ISPRA 8-9 June Crop type distribution in EU What are the need and how precise should it be? ? -Use of national statistics -Use of co-drivers: Land use maps, soil type, climate, FADN (Farm Accountancy Data Network) 50*50 km2 10*10 km2 5*5 km2 1*1 km2 100*100 m2

NOMIRACLE, ISPRA 8-9 June Available crop growth data National, regional and local level from Statistical Bureaus NUTs 1 - National NUTs 2 - Subnational (e.g. Bundesländern in Germany) NUTs 3 - County NUTs 4 - Municipality NUTs 5 - Parish If higher NUTs are used there is less need for other co-drivers to determine the actual crop growth in different areas

NOMIRACLE, ISPRA 8-9 June ENRISK risk mapping Source: Environmental Risks from Agriculture in Europe

NOMIRACLE, ISPRA 8-9 June Conclusions The risk to be mapped should be defined cleary - in relation to toxicity (acute, chronic and selectivity) -in relation to concentration (pesticide directive) Climatic conditions should be taken into account -degradation rate, DT50 -pesticide movement in soil (water flow) -higher pest pressure in warmer climates Crop growth -land use maps are very essential to define areas with high risk -high value crops are sprayed more intensively than low value crops If the risk is additive then a simple distribution based on expert judgement will often be sufficient If the risk is considered to increase for certain pesticide combinations then data based on questionnaires should be preferred in order to include actual farming practice
