CFIA gene editing non-novel status concerns Canadian organic growers

Canadians involved in organic food production have raised concerns regarding the potential impact of updated Plants with Novel Traits guidance from the Canadian Food Inspection Agency (CFIA). Meaning they are not on the same list as genetically modified organisms that contain foreign DNA. This also means a different level of oversight.  

This update clarifies how CFIA’s product-based novelty approach extends to gene editing (for example: that edited crops are not novel if they do not include DNA from another species (foreign DNA) and do not have the capacity to negatively impact the environment). 

Certified organic seed is the required starting material for organic agriculture but, Canadian Organic Standards allow for the use of conventional seed in the time of seed shortages.  

Gene-edited varieties cannot be readily distinguished from conventional varieties, so there is a concern that organic farmers may inadvertently purchase and plant gene-edited seed. Even if it is an honest mistake, organic certification would be withdrawn for three years. 

A technical committee was struck to look at the issue, one recommendation – the Canadian Variety Transparency Database. The goal of this database is to provide a clear distinction between commercial seed varieties that have undergone gene editing from those that have not. The database should be comprehensive and clearly identify any commercial gene-edited varieties sold in Canada.

Wheat Yields in USA and China Threatened by Heat Waves Breaking Enzymes

Video: Wheat Yields in USA and China Threatened by Heat Waves Breaking Enzymes

A new peer reviewed study looks at the generally unrecognized risk of heat waves surpassing the threshold for enzyme damage in wheat.

Most studies that look at crop failure in the main food growing regions (breadbaskets of the planet) look at temperatures and droughts in the historical records to assess present day risk. Since the climate system has changed, these historical based risk analysis studies underestimate the present-day risks.

What this new research study does is generate an ensemble of plausible scenarios for the present climate in terms of temperatures and precipitation, and looks at how many of these plausible scenarios exceed the enzyme-breaking temperature of 32.8 C for wheat, and exceed the high stress yield reducing temperature of 27.8 C for wheat. Also, the study considers the possibility of a compounded failure with heat waves in both regions simultaneously, this greatly reducing global wheat supply and causing severe shortages.

Results show that the likelihood (risk) of wheat crop failure with a one-in-hundred likelihood in 1981 has in today’s climate become increased by 16x in the USA winter wheat crop (to one-in-six) and by 6x in northeast China (to one-in-sixteen).

The risks determined in this new paper are much greater than that obtained in previous work that determines risk by analyzing historical climate patterns.

Clearly, since the climate system is rapidly changing, we cannot assume stationarity and calculate risk probabilities like we did traditionally before.

We are essentially on a new planet, with a new climate regime, and have to understand that everything is different now.
