My previous post on pesticides attracted some interest, so I wanted to follow up with simple to digest bits about the upsides of genetic engineering. Ill tie it back to why it might eventually be a critical technology for application in the vineyards too (since this is WineMag). Pass the smelling salts for everyone who just fainted at that and lets get started. <\/p>\n
Again, a quick clarification on some terms used. <\/p>\n
Since RoundUp\/glyphosate is quickly becoming a straw man in this whole debate, Ill pull in a few different examples of existing and potential advancements. There are, of course, concerns about GE tech. Maybe Ill round out this tangent with a third piece focusing on the real issues vs the imagined ones. But for today, I want to focus on the good stuff: <\/p>\n
Bt crops with built-in pesticidesBt toxins (proteins from a bacteria called Bacillus thuringiensis) have been inserted into transgenic crops to confer resistance against certain insects. In 2013, Bt brinjals were introduced commercially in Bangladesh as part of GM trials. To date, it has been planted on 12 ha across 120 farms. These farmers have cut pesticide use by 80% so far a rate which would not only alleviate negative environmental effects but also the health of farmers. Farmers are also reporting unprecedented increases in yield, which bodes well for their economic well-being. <\/p>\n
Golden Rice the unavailable lifesaverThis one kills me. But not literally. Not like Vitamin A deficiency kills thousands of children annually, and leaves many thousands more disabled. Between 250,000 350,000 children go blind each year due to Vitamin A Deficiency. Golden Rice a GE cultivar enriched with Vitamin A has been available since 2002. Syngenta had been key in developing the technology and essentially made it freely available for use, in an attempt to bypass opposition from the anti-GMO lobby. It didnt work. The technology was opposed and Golden Rice remains unused aside from a handful of free licenses for subsistence farming not nearly the potential scale to make a significant difference in communities severely affected by malnutrition. <\/p>\n
Organic cotton a celebrity gets it wrongIn 2016, Emma Watson wore a Calvin Klein dress, made in collaboration with green consultancy Eco-Age. Via Instagram, Ms Watson extolled the virtues of organic cotton above conventional, specifically that organic cotton is farmed without using harmful chemicals. It seems that Hermione didnt do her homework this time around though. The Bt technology I mentioned previously is also in cotton. While not as harmful as, say, copper sulfate, organic cotton farmers do spray their crops with Bt and other substances to battle severe crop damage from insects. Farmers growing Bt cotton have reduced their insecticide spraying significantly. States like Oklahoma report yields doubling over the past 20 years, improved fibre quality, better weed control and insecticide use down by more than 50%. You know what that is? Thats an improvement in sustainability. Impressive, no? <\/p>\n
What about grapevine?The potential for GE technology in grapevine (including whats being worked on and what has been proposed) is a topic for discussion all on its own. It should definitely be noted that the potential application for GE technology is not limited to pest control. The creeping effects of climate change will eventually irrevocably change the viticulture landscape. The ability of different regions to produce quality grapes will change as rainfall and temperatures rise or fall outside the ideal conditions for grape growing. <\/p>\n
If a technology was available to mitigate these effects a grapevine that can deal with increased CO2 levels, or one that is able to produce equivalent yield at higher temperatures and prolong a wine regions lifespan in the face of major climate shifts, isnt that something we need to consider reasonably, and without hysteria? <\/p>\n
