GM crops 'good for farmers and the environment', study shows

GM crops are good for the economy and can reduce the amount of pesticides used in agriculture, that is according to a new study by the German Federal Ministry of Economic Cooperation and Development (BMZ) and the European Union's Seventh Framework Programme.

Despite the rapid adoption of genetically modified (GM) crops by farmers in many countries, controversies about the technology continue. Uncertainty about GM crop impacts is one reason for widespread public suspicion, the report highlighted.

The results of the study found on average, GM technology adoption has reduced chemical pesticide use by 37%, increased crop yields by 22%, and increased farmer profits by 68%. Yield gains and pesticide reductions are larger for insect-resistant crops than for herbicide-tolerant crops. Yield and profit gains are higher in developing countries than in developed countries.

"The meta-analysis reveals robust evidence of GM crop benefits for farmers in developed and developing countries. Such evidence may help to gradually increase public trust in this technology.

"Numerous independent science academies and regulatory bodies have reviewed the evidence about risks, concluding that commercialised GM crops are safe for human consumption and the environment."

There are also plenty of studies showing that GM crops cause benefits in terms of higher yields and cost savings in agricultural production, and welfare gains among adopting farm households.

"Yield gains of GM crops are 14 percentage points higher in developing countries than in developed countries. Especially smallholder farmers in the tropics and subtropics suffer from considerable pest damage that can be reduced through GM crop adoption," the report said.

"Another concern often voiced in the public debate is that studies funded by industry money might report inflated benefits. Our results show that the source of funding does not significantly influence the impact estimates. We also analyzed whether the statistical method plays a role. Many of the earlier studies just compared yields of GM and non-GM crops without considering possible differences in other inputs and conditions that may also affect the outcome. Net impacts of GM technology can be estimated with regression-based production function models that control for other factors. Interestingly, results derived from regression analysis report higher average yield effects."

"One limitation is that not all of the original studies included in this meta-analysis reported sample sizes and measures of variance. This is not untypical for analyses in the social sciences, especially when studies from the grey literature are also included. Future impact studies with primary data should follow more standardized reporting procedures. Nevertheless, our findings reveal that there is robust evidence of GM crop benefits. Such evidence may help to gradually increase public trust in this promising technology."

EU countries granted flexibility over GM

Long-awaited draft plans to allow EU member states to restrict, or ban, the cultivation of crops containing genetically modified organisms on their own territory even if it is allowed at EU level won the support of the Environment Committee on Tuesday.

MEPs voted to remove the Council-backed idea of a phase of negotiations with the GMO company, and supported plans to allow member states to ban GMO crops on environmental grounds.

"This vote shows we have secured a broad consensus between the political groups in the European Parliament on this sensitive issue" said Frédérique Ries (ALDE, BE) who is steering the legislation through Parliament.

"The measures approved today will secure flexibility for member states to restrict, ban the cultivation of GMO crops if they so wish. At the same time, we have secured a clear process for the authorization of GMOs at EU level, with improved safeguards and a key role for the European Food Safety Authority, which is important for us" she added.

The approved text would entitle member states to pass legally binding acts restricting or prohibiting the cultivation of GMO crops after they have been authorised at EU level. They could also ask, when a new GMO crop is being assessed at EU level, to adjust the geographical scope of the authorisation.

Bans could be founded upon, inter alia, the aims of environmental policy, town and country planning, land use, agricultural policy, public policy, or possible socio-economic impacts. Further possible grounds should include preventing GMO contamination of other products, persistent scientific uncertainty, the development of pesticide resistance amongst weeds and pests, invasiveness, the persistence of a GMO variety in the environment or a lack of data on the potential negative impacts of a variety, MEPs say.

Case-by-case risk assessments to be carried out by the European Food Safety Authority should take account of the direct, indirect, immediate, delayed and cumulative effects of GMOs on human health and the environment, and always take account of the precautionary principle, MEPs say.

Member states should also ensure that GMO crops do not contaminate other products, and particular attention should be paid to preventing cross-border contamination, for instance by implementing “buffer zones” with neighbouring countries, MEPs say.

The committee's second reading recommendation was approved by 53 votes to 11 with 2 abstentions. The committee also voted for the opening of negotiations (57 votes to 5 with 4 abstentions) with the Italian Presidency of the Council, which will start today.

S&D spokesperson on health and climate, MEP Matthias Groote, said: "The Parliament has given itself a strong mandate in the upcoming negotiations with the Council of the EU.

"It is a fact, that the overwhelming majority of European citizens do not support the cultivation of GMOs. This position must be reflected in the final outcome of the negotiations."

Gilles Pargneaux, who is the S&D member responsible for this file, said: "GMOs are a good example of what the Parliament does or tries to do to champion citizens' rights before the Commission or the Council.

“I welcome the adoption of a complete and very balanced report by Frédérique Ries. Once improved by our amendments, this report will faithfully reflect the position taken by the Parliament at first reading.

“This proposal brings more legal certainty to member states willing to limit or ban GMO cultivation in their territory. In future, they will be able to invoke new grounds: environmental policy, socioeconomic reasons or the need to avoid GMOs in other agricultural products.

"This report includes most of S&D's priorities, such as the choice of the environmental legal basis, a more extensive list of reasons for banning, the need to have binding measures on coexistence in order to avoid the contamination of traditional cultivations by GMO cultivations, reinforcement of the risk evaluation method by the European Food Safety Evaluation (EFSA) and far greater transparency in the banning procedure.”
