Roundup the Roundup! Part one: What is glyphosate?

6 September 2017

Our agri-activism volunteers in Wales are getting stuck into campaigning against harmful agricultural practices. Costas Kaloudis tells us about why they are fighting the herbicide glyphosate in particular. 

 

Tackling glyphosate

My first blogpost about my agri-activism placement at Caerhys farm in Wales is different than expected. While I am certainly eager to report on many good experiences and learnings that I have had so far, we have been so busy making and executing various plans that I was left with no time for reflection and writing. But now we are up to some proper activism and therefore I decided to deviate from the normal order of doing things and get straight to the essence of this placement: Working and campaigning for healthy, clean and sustainable agricultural and food systems.

Many learnings and experiences I have had here are worth telling a lot about, but they will come a bit later. For now we are busy campaigning about glyphosate, which we have set as a main goal of our placement this summer. The reasons for this will become clear, by reading this and the follow-up post.

About glyphosate

Glyphosate is the main active ingredient in many herbicide products. Its herbicidal properties were discovered by researchers of the multi-national agri-business Monsanto. Four years later it was brought to market in the renowned product that has become the company's flagship ever since: Roundup. Glyphosate is a non-selective herbicidal ingredient used to control both broadleaf grass and weeds.

As for the farming use of it, statistics of 2014 in the United Kingdom show that 2,241,105ha of land are treated with glyphosate (an area the size of Wales) with a total of 1.910, 524kg of product being sprayed.1 That is a 3,000% increase in 20 years. Glyphosate is applied to a wide range of crops including cereals, oilseed rape, field beans, sunflowers, grain, maize, sugar beet and grassland. By now it is also commonly used for gardens and public areas. It accounts for around 25% of the global herbicide market. It is a very effective ingredient as it is simple to use and cost-effective for farmers and therefore was quickly and widely adopted. Monsanto has also sub-contracted it to other companies, but after the patents expired, many other companies have produced equivalent products.

What's the matter with glyphosate?

The circumstances stated above mean that we are all exposed to this ingredient through our food consumption (except for those who only eat organically grown food). It is likely that your municipality and your neighbours also use it in alongside roads and pavements and/or their gardens. Indicatively, pesticide residues in UK bread have risen from 28.24% in 2001 to 63.43% in 2013. That would equate to three out of every five non-organic bread products on the market.2

In other words, glyphosate is all around us and also in our food.

Is that a problem? Yes, it is.

In general, there's strong evidence that this herbicide compound causes birth defects and probably causes cancer. There's also reason to believe it causes or exacerbates numerous chronic illnesses. The most high profile report about the harmful consequences of glyphosate for humans was made by the World Health Organisation (WHO) after IARC - the organisation's cancer research arm- published an assessment in March 2015 stating that the herbicide solution is "probably carcinogenic to humans".

However, apart from the cancerogenic effect on human cells, when one starts to look at the details and the likely effects of glyphosate (many of them proven through animal testing), facts get quite scary. Research has been done by many institutions and the following are some of the highlights:3

- Even small amounts of Roundup lead to death of human cell cultures (research by professor Gilles Seralini and his team of the University of Caen, France).4

- Glyphosate has been found over the safe limit in all urine samples from the drinking water in a research by the University of Leipzig. None of the examinees had direct contact with agriculture.5

- Direct contact with glyphosate (e.g. by farmers, gardeners or amateur users) is by now almost certain to cause cancer

- High levels of glyphosate were found in 3 out of 10 American women's breast milk. Surveyed mums were mostly aware of glyphosate and actively avoiding it.6

- Around 44% of samples from 18 EU countries contained significant glyphosate residues. The UK ranked 3rd highest (70% of participants).7

- Glyphosate is found to stay in soil for a long time. It inhibits useful bacteria and algae, thus increasing the incidence of harmful fungi. In addition, glyphosate can cause micronutrients, especially Manganese, to become unavailable and thus inhibit photosynthesis. A similar process is suspected to take place in the digestive tract of humans and animals.8

- Is suspected to contribute to Alzheimer's, Cancer, Autism, Birth Defects, Brain Cancer, Gluten Intolerance, Obesity, Colitis, Heart Disease, Liver Disease, IBS, Parkinsons, Obesity, Infertility, Aggression & Depression.9

- Honey Bees are certainly affected10 and so is much biodiversity after exposure absorption of glyphosate.

Of all these effects, the ones to humans are harder to establish with certainty. To do that with proper scientific rigour takes time. Of course, the producer companies claim that the small doses of glyphosate residues that one receives through diet do not pose any health risks. But all independent research that has been done on the matter tells a different story, at least pointing to some health risks.

For a person like me, who understands science well, the available evidence is more than sufficient to be alarmed. Enough has been known about the harmful impacts of glyphosate-based products for a long time and I was looking forward to take some action about it. Fortunately, I came to the right place for that.
