DORCHESTER (April 2, 2007) — Although EU plantings of GM insect resistant (Bt) maize were only 65,000 ha in 2006 (in 7 countries), the crops have been delivering income gains to the farmers planting the crops, health benefits for the human and livestock consumers from improved grain quality and environmental gains associated with lower insecticide use, according to a study released today.

“Farmers, consumers and the environment all gain from adoption of this technology. It is therefore somewhat ironic, that by largely ignoring its application in the EU, we are denying ourselves these benefits” said Graham Brookes, director of PG Economics, and author of the study. 

The study offers the first comprehensive quantifiable look at the impact of GM insect resistant (Bt) maize crop production in the EU since 1998 when the first commercial crops were planted in Spain.”
The key findings in the study, “The benefits of adopting genetically modified, insect resistant (Bt) maize in the EU: first results from 1998-2006 plantings” were:

  • In maize growing regions affected by European Corn Borer (ECB) and Maize Stem Borer (MSB), the main impact of growing Bt maize has been higher yields compared to conventional non-GM maize. Average yield benefits have often been +10% and sometimes higher;
  • In 2006, users of Bt maize have, on average, earned additional income levels of between €65 and €141/ha. This is equal to an improvement in profitability of +12 to +21%;
  • In certain regions, Bt maize has delivered important improvements in grain quality through significant reductions in the levels of mycotoxins found in the grain. This delivers a health benefit to the livestock sector that mostly consumes the maize (but could be available to the human food sector, if used)
  • Where farmers have previously used insecticides to control ECB and MSB, adoption of Bt technology has delivered environmental gains from less insecticide use and reduced use of fuel. Reduced fuel use is contributing to lowering carbon emissions

What Is (risk) Appropriate Regulation Of Gene Editing Technology?

Despite the much-hyped expectation that Europe was on course to follow other parts of the world in removing GMO-style regulatory requirements from gene edited (GE) crops, with EU elections looming and no agreement in sight the bloc now risks slipping back towards precautionary inertia. Summarising their recent peer-reviewed paper exploring risk-appropriate regulation for gene editing, agricultural economists Graham Brookes and Stuart Smyth warn that we must learn the lessons from past experience of divergent international regulation of agricultural innovations. The impact of over-precautionary EU regulation of gene editing will not only disadvantage European agriculture, but will also compromise global efforts to address urgent climate, biodiversity and food security challenges, they argue.

Feeding The Uk Sustainably: Time For Policy Inaction To End

As Ministers prepare to unveil a new land use framework for England this autumn, the scientific evidence behind land sparing as the most effective farm policy for delivering food production, climate and biodiversity goals is compelling. Why then does the UK government continue to favour a land sharing approach through its environmental land management schemes? The recent ‘re-interpretation’ of an expert land use report for the large, land-owning NGOs who commissioned it may provide some clues, writes agricultural economist Graham Brookes.

European Court Ruling On Neonicotinoids Further Highlights Muddle Created By Ongoing Eu Regulatory Inconsistency And Dysfunction

The recent Court of Justice of the European Union (CJEU) ruling that EU Member States can no longer grant derogations (exemptions) for the use of neonicotinoid seed treatments to control pests in arable crops like sugar beet and oilseed rape raises a number of important questions and highlights the regulatory inconsistency and muddle that the European Union (EU) has created for itself

Feeding The World Sustainably: Crop Biotechnology Continues To Make A Significant Contribution, Concludes New Research

GM crop technology continues to make an important contribution to reducing the environmental footprint of agriculture and securing global food supplies in a sustainable way. It has reduced pressure to bring new land into agriculture, which is vital if the world is to maintain and restore the natural habitats and vegetation that are best for many species of plants and animal life and for storing carbon” said Graham Brookes, director of PG Economics, author of the research.
