Crop biotechnology continues to provide higher farmer income and significant environmental benefits
Published: 15th July 2020
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.
New paper quantifies 15 years of economic and environmental benefits from using biotech-GM crops in Colombia
Published: 11th February 2020
Highlights in the peer reviewed 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.
Asian farmers would see annual weed control costs increase by $1.4 to $1.9 billion due to potential restrictions on glyphosate use, new study reports
Published: 25th March 2019
A new paper published in the journal Agbioforum (1) points to higher weed control costs, less effective weed control, more difficult access to fields and lower yields, if farmers in seven Asian countries could no longer use glyphosate. The peer reviewed paper written by Graham Brookes of PG Economics Ltd examined the current use of glyphosate, the reasons for its use and what changes farmers would make to their weed control programs if glyphosate was no longer available for use. Seven countries were included in the study – Australia, China, India, Philippines, Indonesia, Vietnam and Thailand – as these were representative of countries where glyphosate use in agriculture is significant, countries that may be considering use restrictions for glyphosate and countries were farmers are planting glyphosate tolerant crops.
UK urged to ‘bring back’ sound science as the basis for regulating crop genetic innovations post-Brexit
Published: 10th October 2018
‘UK plant genetics: a regulatory environment to maximise advantage to the UK economy post Brexit’ considers three future scenarios for the regulation of gene edited crops and genetically modified organisms (GMOs), ranging from maintaining current alignment with the EU through improved implementation of EU rules, to the UK setting its own regulatory path on both GMOs and NBTs.
