Seeds of Hope for the Global Food Systems and Biodiversity Crises

According to the United Nations projections, the world population will increase to 8.5 billion by 2030, as humanity faces one of their biggest challenges, food insecurity. Almost 193 million people in 53 countries suffered acute food insecurity in 2021.

Major producers around the world need to turn away from the damaging industrial agrochemicals and pesticides that are magnifying the current issues and explore new innovative techniques to ensure the world’s food security for the future.

Approximately USD 44tn of economic output – more than half of global annual GDP – is moderately or highly reliant on natural capital. Yet, humans have already transformed more than 70% of the Earth’s land area from its natural state, causing unparalleled environmental degradation and contributing significantly to global warming, according to UNCCD Global Land Outlook latest report.

“Our health, our economy, our well-being depends on land. Our food, our water, the air we breathe are all coming from the land, at least partially,” said Ibrahim Thiaw, executive secretary of the UNCCD, in a call with reporters. “Humanity has already altered 70 percent of the land. This is a major, major figure.”

If degradation of the land keeps increasing at this rate, scientists predict that there will be large-scale food supply disruption, increase in biodiversity loss, extinction, more zoonotic diseases and decline human health, giving rise to poverty, hunger and pollution.

“Time is short, and the situation is dire,” said Qu Dongyu, the Direct-General of the Food and Agriculture Organisation (FAO). He added there needed to be a “transformation of agrifood systems to be more efficient, inclusive, resilient and sustainable”.

Agroecology & Biocontrols VS Industrial Agriculture & Pesticides


The world’s industrial food systems haven’t found a solution to the food and biodiversity crises yet, mainly due to the fact that the solution may not appeal to the agribusiness giants, including the agrochemical industry, governments and world development banks, who usually seem to set the agenda and policies for the sector.

According to the International Fund for Agricultural Development, Public Development Banks invest about $1.4tn per year in the agriculture and food sector.

A report by the Action Group on Erosion, Technology and Concentration (ETC Group), ‘Who Will Feed Us?’, mentions that small-scale producers provide food to 70% of the world, while using only 25% of the resources.

After all, there’s a solution to these crises available, a solution that serves people’s interest and the environment, instead of agribusiness corporations, public development banks and governments. We should be supporting agroecology as the solution to the food and biodiversity crises.

According to UNFSS, we don’t need “sustainable intensification”, “climate-smart agriculture” or ‘nature-positive solutions,” which often greenwash corporate agendas. Millions of smallholder farmers, fishermen, pastoralists, agricultural and rural workers, and entire indigenous communities practice agroecology, a way of life and a form of resistance to an unfair economic system that puts profit before life.

Pesticide Action Network UK (PAN-UK) are the only UK charity focused solely on tackling the problems caused by pesticides and promoting safe and sustainable alternatives in agriculture, urban areas, homes and gardens. PAN-UK promotes agroecological practices, guiding and supporting farmers across the world.

Agroecology practices include putting farmers first, promoting soil health, biodiversity and natural ecosystem function, integrating science with knowledge and practice, promoting complexity over simplicity, minimising waste and optimising energy.

According to PAN-UK, less than 0.1% of pesticides applied for pest control reach their target pests (Pimental, 1995). Replacing chemicals that cause harm to our health and biodiversity, including soil degradation, is essential. Agroecology improves farmers’ profitability, yield, health, food security, and better opportunities for women farmers.

Pesticides can damage our health, biodiversity, wildlife, pollute the air we breathe, the water we drink, soil, plants and everything else it touches. It’s also the cause of suicide and accidental deaths mainly in the global south. These toxic chemicals must be replaced with biological control or biopesticides.

Biocontrol

Biological control, or natural control, is a component of an integrated pest management strategy. It’s the reduction of pest populations by natural enemies, biological control of insects, weeds and plant diseases. Biocontrol is safer for the end-user and the environment.

The approval process and authorisation of innovative biocontrol is still slow, complex and differs from country to country. There is an urgent need to rethink data requirements on risk assessments and also create a worldwide integrated and simplified regulatory system, so every country is on the same page. This would also facilitate trade between countries and at the same time help to reverse biodiversity loss globally.

“We need a strong voice lobbying for biocontrols at the highest levels of government”, mentioned Nick Mole, PAN-UK policy officer at the World BioProtection Awards 2022.

Since Brexit, the UK’s deregulation plans on pesticides and GMO food have caused some concern, including possible free trade agreements with countries with lower food standards. The UK population may be consuming products with high level of pesticides, including unlabelled genetically engineered foods that may be available as early as 2023. Are we prepared to accept this?

“The indirect consequence is that people are starving in Africa because we are eating more and more organic products”, said, Erik Fyrwald, the CEO of Chinese-owned agrochemical giant Syngenta, to NZZ. This statement showed his opposition to organic farming.

Syngenta produces pesticides and GM seeds. The company’s Huddersfield factory exported a staggering 12,000 tonnes of the herbicide Paraquat and others in 2020. Paraquat was banned for use in the UK since 2007, as it’s been linked to be lethal to humans causing kidney failure, liver damage, DNA damage, Parkinson’s disease and death.  

A very interesting move from Syngenta Crop Protection AG is their recent acquisition of two products, NemaTrident® and UniSpore®, from UK-based biocontrol technology developer Bionema. Is this a sign that change may be under way?

With the right support from governments, farmers are keen to accept more sustainable solutions to protect their crops, retailers and the public are open and interested in healthier products and protecting the environment, therefore legislators should be on their side facilitating this process, turning this into a win-win situation.

This is time for corporations, scientists, environmentalists, activists, farmers, growers, the public, governments, legislators, regulators, and the entire world to come together and accept that change is essential to our survival and it must happen now!

Do We Fully Understand the Implications of GMOs?

Monica Piccinini

16 Sept 2021

The subject of genetically modified foods has been debated for many years. In fact, genetically modified produce is freely available in a number of developed countries. The benefits as well as the negative side-effects have polarised opinion in the scientific world, advanced economies and amongst health conscious populations.

Technological advances in key areas of science are now lifting the debate to new concerning levels.

“GMOs appear the focus of a stunning program: to privatize biology itself, turning sovereign soils and the very act of farming, as much as its produce, into commodities”, wrote Rob Wallace in his book “Big Farms Make Big Flu”.

GMOs (genetic modified organisms) describe foods that have been created through genetic engineering. Scientists identify what trait they want a plant, animal or microorganism to have (such as resistance to pesticides, herbicides or insects), they then copy it and insert the gene into the DNA of the plant, animal or microorganism.

In 1866, Gregor Mendel, an Austrian monk, was able to breed two types of peas, identifying the basic process of genetics. In 1922, the first hybrid corn was produced and sold commercially. In 1994, the first genetically modified produce created through genetic engineering becomes available for sale, a genetically modified tomato.

Since then, science has been advancing and progressing rapidly, as we enter a new phase of genetic engineering. NBT’s (new breeding techniques) such as CRISPR and RdDM, as well as synthetic biology, allow more complex changes to the genetic makeup.

What seems like incredible biological acts of ‘science fiction’ are still very early in their development. Moving too fast in order to commercialise these technologies will undoubtedly see the negative side effects with unintended consequences.

CRISPR cuts the cell’s DNA at a particular site. Like a wound, the cell attempts to heal itself by resealing its break using DNA repair mechanisms. This process can be faulty and not always works perfectly, causing unforeseen problems with unexpected results (new DNA).

In the 1960’s plant scientists in the U.S. bred a new potato variety that was ideal for making into crisps but also contained dangerously high levels of natural toxins. The potato had to be withdrawn from the market in 1970.

There is large concern over GMOs across the world with the sense that gene editing could give rise to dangerous mutations or crops that could be patented by large agribusiness corporations trying to monopolise staple crops.

There are also other factors involved, such as the creation of plants, animals and microorganisms we have not seen before, and by doing so, the impact it may have on our health, the environment as well as evolutionary patterns. Potential risks and biosafety concerns are associated with it. Little is known about the long-term effects and safety associated with GMOs.

According to GMWatch, a number of disadvantages of GMOs foods to humans and the environment have been listed, including allergic reaction by allowing a certain allergen present in the GM crop to enter the body and stimulate an immune response.

Toxicity is also in question. GM foods may increase the production of toxins at levels harmful to humans, as toxins are produced when there is damage in the “gene of interest” during the insertion process. Another concern is reduced nutritional value of GMOs. By making a plant more resistant to pests, the antioxidant phytochemicals are reduced. 

Toxins may also be released into the soil causing environmental damage.  An example of this is soil bacterium, bacillus thuringensis, present in larval caterpillars, which has a gene that produces certain toxins that destroys insects as well as pests. This gene is inserted into the corn to make it resistant to pests, resulting in the release of toxins into the soil, therefore turning the soil less fertile.

In addition to this, there is also the danger of resistance of pests to toxins, antibiotic resistance, genetic hazards, flow of genetic information, generation of super-weeds, and disruption to biodiversity by interfering the natural process of gene flow.

The United States, Canada, Brazil, India and Argentina have been growing GMO products made from modified soya beans and corn for many years. The majority of U.S. corn, canola, soy, cotton and sugar beets crops are GMOs.

“Let’s start now to liberate the UK’s extraordinary bioscience sector from anti-genetic modification rules, and let’s develop the blight-resistant crops that will feed the world”, said Boris Johnson in his first speech as UK’s prime minister.

Michael Antoniou, professor of molecular genetics at King’s College London, mentioned that the answer is to change our food delivery systems in the direction of “agroecology” by reducing the use of synthetic ferlitisers, pesticides and herbicides, and planting a diverse range of plant strains, to build resistance into the system. At the very least, any crops produced by using genetic editing must be labeled as such.

Liz O’Neill, director of GM Freeze, argues that genetic engineering should undergo strict regulation. She said:

“If this group of genetic engineering techniques escape classification as GM, they could be completely unregulated. The crops they produce could find their way into our fields and on to our plates without environmental or food safety risk assessments. They would not be traceable and, without labeling, consumers would have no way to identify and avoid them should they wish to do so”.

Since the UK left the EU, it has the power to authorise new GMOs. Brexit legislation gave Defra (Department for Environment, Food and Rural Affairs) more power to amend existing GMO laws without going to Parliament.

“Gene editing is a sticking plaster, diverting vital investment and attention from farmer-driven action and research which could be yielding results, right now”, said Gareth Morgan, SA’s (Soil Association) head of farming and land use policy.

“Consumers and farmers who do not want to eat or grow genetically modified crops or animals need to be offered adequate protection from this. The focus needs to be on how to restore exhausted soils, improve diversity in cropping, integrate livestock into rotations and reduced the dependence on synthetic nitrogen and pesticides”, added Morgan.

Recently, GMWatch reported that a U.S. based fake meat maker, Impossible Foods, that uses genetically engineered ingredients, have gone past regulators, mainly in the U.S. and Canada, and are looking into expanding its products into the New Zealand and Australian markets.

Impossible Foods adds GM soy leghemoglobin (SLH), 0.8% and not labeled, in order to make its product look and feel as if it’s bleeding, just like real meat. The issue is that SLH does not have a history of safe use in food.

A rat feeding study that Impossible Foods commissioned on SLH showed worrying effects in the rats, including signs of inflammation, decreased blood clotting ability, changes in blood chemistry, kidney disease and possible signs of anemia.

Would you swop a vegetable burger that tastes of vegetables to a burger that tastes and bleeds like real meat but has been genetically modified with SLH, a product that has not been tested extensively? Are we going too far and too fast without calculated risks? What is the limit to greedy corporations?

Reported by GMWatch this month, five hundred tons of unauthorized GMO rice flour that had been illegally imported by India and sold in the European Union had to be recalled, but authorities could not guarantee that all products would be removed from the market. These batches of white rice were imported into Europe, transformed into rice flour, and sold on the market as an ingredient, including chocolate sweets from the Mars company.

Do we have the assurances and guarantee that genetic engineering will not be responsible for the creation of new disease organisms with no natural resistance and no available cure? Do we have the confidence that these “novel foods” will not harm our environment and our health? Will our scientists, world leaders and corporations assure the world GMOs are 100% safe?

Many questions are yet to be answered. Discussion and debate over the benefits and risks of genetic engineering as well as the ethical questions raised by this technology is essential. We must ask for total transparency and full participation in the decision making process. There is too much at stake, as this may lead us to a path of no return.
