Introduction - Proposal finalising HairMeeting in Brussel on July 9, 2009 with EC

and Hair consortium representatives

Alterra will propose how to solve the problems with the current Hair software, taking into account

The Hair contract and Hair project results Recommendations and issues raised by

Arcadis Belgium BV Discussions at the Working Group Meeting

in Poznan, October 14, 2009

Proposal finalising HairApproach

Make a more robust version of Hair Select the indicators that can be used

without problems by the Commission and MS (and discard those with problems related to data availability)

Test the selected indicators and improve the (technical) documentation of the software

Hair Database components

GIS related data Compound data Usage and sales data

Hair Database components – GIS related dataClimate, soil, land use,

surface water data are stored at 10K and 25K resolution

These different resolutions give the same information

We propose to remove the 25K resolution from the current database

Hair Database components – Compound data (1)The current compound database in Hair

consists of multiple tables originating from different research institutes

The design is complex and difficult to manage by the users

Problems with data integrity and redundancy can be expected

Hair Database components – Compound data (2)We propose To implement one single format that

contains all compound properties required

To implement less strict rules for the replacement of missing compound properties within Hair

To improve the interface between the Hair compound database and the external database used by EUROSTAT

Hair Database components – Use data

Hair contains use data at 2 scale levels

Regional based applications (NUTS1)

Field based application patterns during a full crop cycle, for calculating SPEAR indicators

We propose to support only the regional scale level

Risk indicators – Terrestrial

We propose To remove (1) and to modify (2) some indicators To remove specific algorithms for granular

applications and seed treatments (3)

Risk indicators – surface water and groundwaterWe propose to remove the SPEAR indicator

(requires field based application patterns during a full crop cycle)

Risk indicators for consumers

Food intake rates for adults, childs (Acute, Chronic)

Cumulation of MRL data based on use data and food consumption data.

Problems due to lack of input data (monitoring food residues, population density, deposition on edible parts and crop parameters)

We propose to leave consumer indicators out of Hair

Risk indicators for workers

We propose to include the indicators for workers and bystanders

Discussion

Agreement has to be reached between Alterra and the Commission on the approach

Our proposal to finish Hair is open for discussion …

Thank you for your attention
