Data Requirements and Conceptual Framework for Agricultural Statistics
Discussion P. Everaers (Eurostat)
‘Agriculture – environment linkages including land use’
11-Dec-2008
Overview
The conceptual framework : agriculture and environment, land use : a mind setter, but not yet a conceptual model
To operationalize ;choices to be made, start with the basic entities
Starting from where : a practical approach land use : the LUCAS example.
Questions for discussion
11-Dec-2008
Elements of a conceptual model (in sociological research terminology)
Choice of entities
Choice of indicators and subsequently variables and items
Scheme of possible relations
In a context : paradigma

The context will lead to the theoretical concepts and determine the (core) variables : there are at least three starting points
1.Supply and utilization of agricultural products Early warning Efficient Market system
2.Poverty and Hunger reduction Food security
3.Agricultures effect on the environment Climate change
11-Dec-2008
Or to start from the current situation in agricultural statistics request the choice of a context
Nothing or very poorly developed, marginally functioning
NSDS as basis: to be adapted
Developed systems
To search for the common denominator
11-Dec-2008
The basic entities : the fundamental choice that at the end defines the quality of the integrated system we are aiming for.
We have to use the entity that facilitates all aims
Survey base
Based on administrative sources
Based on ‘more advanced’ techniques

What is LUCAS?
LUCAS is a field sample survey for collecting data on land cover/use and agro-environmental indicators
Organised by Eurostat every 3 years
LUCAS data is used for producing harmonised land cover/use data for EU countries
Main data users are DG ENV, DG JRC, DG ENTR, DG ARGI, DG REGIO and European Environment Agency

LUCAS is a field sample survey for collecting data on land cover/use and agro-environmental indicators

LUCAS data is used for producing harmonised land cover/use data for EU countries
But can also be used to collect and link with a lot of other information

Questions / points for discussion
What do we miss when we measure on the household level? Can we manage with aggregated information
The strategy should distinguish levels of implementation according to the context (paradigma) in combination with the level of development (nothing to poor systems – NSDS – developed systems), and accordingly should use different levels of conceptual models.
One global model, is this possible ?
11-Dec-2008
Q and D : Cont’d
The entity to start with in the integrated (conceptual and data) model is on the spatial level : the spatial coordinate or the area code
Is the current draft strategy in its conceptual model maybe too much developed country oriented : should we not focus on the MDG related actions?
A layered conceptual model, also from the point of view of feasibilty for introducing the strategy seems to be needed
