SciDev.Net hosted a live debate on genetically modified (GM) organisms on this page on Wednesday 11 June.

See the comments below to read the debate.

The arguments about GM continue to rage in farming, research and development communities across the world. Some declare the technology to be an environmental hazard and a threat to smallholder farmers. Others say it can feed billions more people in the face of climate change, water scarcity and population growth.

In the lead up to this debate, we published a series of opinions on GM by experts from the SciDev.Net regions. These experts will now lead the discussions about the science of GM and unlock some of its myths. How can countries regulate its use? Why is it such a controversial topic and, within all this, what exactly is wrong with GM?

The debate will take place in the comment section below. Please login below and add your comments and questions on the thread.

We will be cross-posting any questions we get via Twitter (@scidevnet) using the hashtag #gmdebate, so please get in touch.


Pervaiz Amir is an agricultural economist and specialist in water, climate change and smallholder agriculture. He is a director of the Pakistan Water Partnership.
Stance on GM: In his SciDev.Net opinion piece, Amir argues that Pakistan’s experience shows that GM technology is unsuitable for small-scale farming.

Mark Lynas is an environmental campaigner and writer. He is also vice-chair of the World Economic Forums Global Agenda Council on Emerging Technologies.

Stance on GM: Until we know more about the benefits and dangers of GM food, Kapiel argues in his opinion piece, fast, effective and cheap tests are needed in his region to ensure people can find out if they are eating such food.

Margaret Karembu is unable to join us today. In her place we welcome Faith Nguthi (biography below). Margaret is director of the ISAAA (International Service for the Acquisition of Agri-biotech Applications) AfriCenter and chair of the Kenyan branch of the Open Forum on Agricultural Biotechnology Programming Committee.
Stance on GM: In her article, Karembu says an anti-GM lobby is using unfounded arguments to block GM crops that could fight food insecurity and environmental degradation.
