Confusing statistics regarding GM maize in Spain


I am currently trying to compile statistics on GM, conventional and organic maize in Spain. Article 31 of Directive 2001/18/EC establishes that Member States shall establish registers for recording the location of GMOs, and make them  known to the public. This means compiling statistics on the situation should be a quite straightforward task. As a person involved in the GM debate in Spain for long time though, I know it is not.

As information to the public, the Spanish Ministry of Agriculture publishes yearly statistics on the surface area cultivated with GM maize (the only authorised GM crop in Europe) on the level of Autonomous Communities. This information is very far from being a useful public register, for example in terms of being the appropriate scale of information to prevent contamination. This data is also produced according to what the biotechnology companies declare as being sold (in units of 50.000 seeds) and this quantity is multiplied by 1,7, which is considered the “normal” sowing dose per hectare. In contrast, the regional Agriculture departments publish data based on what variety the farmers state they grow when applying for the CAP subsidies. Differences in the figures presented by these two levels of the agriculture authorities are as high as 66%, as reported by a coalition of NGOs and farmers unions linked to agriculture and environment in Spain.

Different hypotheses for the discrepancies could be posed: a) Either farmers do not declare the variety they will grow (deliberatively or because they do not know or they have not decided when applying for the subsidies), or b) The biotech companies are exaggerating the numbers so it looks like adoption rates in Spain are much higher than the actual figures. Both (and other possibilities) could also be happening at the same time.

In the graph below you can see the number of hectares of GM maize in Catalonia depending on the data source, and the difference (%) between the two data sets for each year. A similar situation can be found for Aragón.

Funnily enough, it is also not easy to get statistics on organic maize in Spain. This is because up until 3 years ago,  the official agricultural statistics did not differentiate the surface area cultivated with maize on its own, simply registering it under the umbrella category of “grains”.

Struggling with how to get an accurate picture of how much GM vs organic maize cultivation is taking place and how this has changed over time leaves me also questioning how it might be possible based on these poor registers to assess in a reliable way what is happening and how coexistence is playing out in Spain.
