Dorchester, UK, 1st October 2020: The first assessment of the farm level impacts of using GM maize in Vietnam [1], published in the journal GM Crops and Food, has found that since 2015, crop biotechnology has helped Vietnamese farmers grow more food/feed and substantially improve their income levels, whilst using fewer resources. It has also reduced the environmental footprint associated with the production of maize.

Biotechnology adoption in corn cultivation in Vietnam shows positive impacts of higher productivity, increased farmer income and environmental improvement. WORKSHOP: CONTRIBUTIONS OF AGRICULTURAL BIOTECHNOLOGY ADOPTION IN VIETNAM
First study of impact of using biotech/GM maize in Vietnam highlights substantial economic and environmental benefits. Highlights in the peer reviewed paper include: 225,000 hectares have been planted to maize containing GM traits in Vietnam since 2015 and in 2019, the technology was used on 10.2% of the total maize crop. The technology has enabled Vietnamese farmers to obtain higher yields from better pest and weed control: the GM varieties out-performed conventional varieties by +30.4% (+15.2% if the yield comparison is with only the nearest performing equivalent conventional varieties). The extra production and reduced cost of pest and weed control have provided maize farmers with higher incomes equal to an average of between US $196 per ha (relative to equivalent conventional varieties) and US $330 per ha (average of all conventional varieties). In terms of investment, for each extra US dollar invested in GM maize seed (relative to the cost of conventional seed), farmers gained an average of between US $6.84 and US $ 12.55 in extra income. These levels of return are at the higher end of the range of performance for similar maize seed GM technology in other adopting countries. Aggregate farm incomes have increased by a total of between US $43.8 million (based on the yield gains relative to the nearest equivalent conventional varieties) and US $74.1 million (based on yield gains relative to all conventional varieties). The maize seed technology has reduced insecticide and herbicide spraying. The average amount of herbicide active ingredient applied to the GM crop area was 26% lower than the average value for the conventional maize area and in terms of the associated environmental impact of the herbicide use[3], it was lower by 36% than the average value applicable to the conventional maize area. Insecticides were used on a significantly lower GM crop area and, when used, in smaller amounts. The average amount of insecticide applied to the GM maize crop was 78% lower than the average value for the conventional maize area and, in terms of the associated environmental impact of the insecticide use, it was also lower by 77%.
PG Economics Report 2020 - Farmers who planted genetically modified (GM) crops increased their incomes by almost $19 billion in 2018 and reduced carbon emissions by 23 billion kilograms or the equivalent of removing 15.3 million cars from the roads that year. The higher income represents $4.42 in extra income for each extra dollar invested, according to a report released today by PG Economics.
Highlights in the peer reviewed[2] paper include: About 1 million hectares have been planted to cotton and maize containing GM traits in Colombia since 2003 and in 2018, the technology was used on the equivalent of 90% and 36% respectively of the total cotton and (commercial) maize crops. Use of this technology has enabled Colombian farmers to obtain higher yields from better pest and weed control (+30.2% from using stacked - herbicide tolerant and insect resistant cotton and +17.4% from using stacked maize). The extra production and reduced cost of pest and weed control have provided maize farmers with higher incomes equal to an average of US $294/ha and an average return on investment equal to +US $5.25 for each extra US $1 spent on GM maize seed relative to conventional seed. For cotton farmers, the average increase in income has been + US $358/ha, with an average return on investment equal to +US $3.09 for each extra US $1 spent on GM seed relative to conventional seed. Farm incomes have increased by a total of just over US $300 million since 2003. The cotton and maize seed technology have reduced insecticide and herbicide spraying by 779,400 kg of active ingredient (-19%) and, as a result, decreased the environmental impact associated with herbicide and insecticide use on these crops (as measured by the indicator, the Environmental Impact Quotient (EIQ)) by 26%. The technology has also facilitated cuts in fuel use, resulting in a reduction in the release of greenhouse gas emissions from the GM cotton and maize cropping area and contributed to saving scarce land resources.
