UK peatlands are being destroyed to grow mushrooms, lettuce and houseplants – here’s how to stop it

Peat is a natural carbon sink but is often found in house plants and other retail products, particularly within the food and farming industry.

During the long, solitary days of lockdown, I found solace in raising houseplants. Suddenly stuck at home, I had more time to perfect the watering routine of a fussy Swiss cheese plant, and lovingly train our devil’s ivy to delicately frame the bookcases.

But I started noticing that these plants, sourced online, often arrived in the post with a passport. Most had travelled from all over Europe, with one common tagline: contains peat.

As a peatland scientist, these labels instantly filled me with horror. Hidden Peat, a new campaign launched by The Wildlife Trusts, is now highlighting the presence of peat in all sorts of consumer products, including house plants.

Peatlands, such as bogs and fens, store more carbon than all of the world’s forests combined. They trap this carbon in the ground for centuries, preventing it from being released into the atmosphere as greenhouse gases that would further warm the climate.

Peatlands have multiple environmental benefits. They are havens for wildlife, providing habitat for wetland birds, insects and reptiles. They supply more than 70% of our drinking water and help protect our homes from flooding.

So why on earth is peat being ripped from these vital ecosystems and stuffed inside plant pots?

From sink to source

Despite their importance, peatlands have been systematically drained, farmed, dug up and sold over the last century. In the UK, only 1% of lowland peat remains in its natural state.

Instead of acting as a carbon sink, it has become one of the largest sources of greenhouse gas emissions in the UK’s land use sector. When waterlogged peat soils are drained, microbes decompose the plant material within it and that results in the release of greenhouse gases such as methane into the air.

Most of the peat excavated, bagged up and sold in the UK is used as a growing medium for plants. Gardeners have become increasingly aware of this problem. Peat-free alternatives have been gaining popularity and major retailers have been phasing out peat-based bagged compost in recent years.

Indeed, the UK government announced they would ban sales of all peat-based compost by 2024. But this legislation has not yet been written and it seems unlikely it will be enacted before the end of the current parliament.

Even if brought in to law, this ban would only stop the sales of peat-based bagged compost of the type you might pick up in the garden centre. Legislation for commercial growers is not expected until 2030 at the earliest. So the continued decimation of the UK’s peatlands could remain hidden in supply chains long after we stop spreading peat on our gardens.

Hide and seek peat

For consumers, it’s almost impossible to identify products that contain peat or use peat in their production. All large-scale commercial mushroom farming involves peat and it is used for growing most leafy salads. It gives that characteristic peaty aroma to whisky, and, as I found out, is a popular growing medium for potted plants.

But you’d struggle to find a peat-free lettuce in the supermarket. The Hidden Peat campaign asks consumers to call for clear labelling that would enable shoppers to more easily identify peat-containing products. Shoppers are also encouraged to demand transparency from retailers on their commitment to removing peat from their supply chains.

You can ask your local supermarket about how they plan to phase out peat from their produce. Some supermarkets are actively investing in new technologies for peat-free mushroom farming.

Make informed purchases by checking the labels on garden centre potted plants or source plants from peat-free nurseries. The Royal Horticultural Society lists more than 70 UK nurseries dedicated to peat-free growing.

You can write to your MP to support a ban on peat extraction and, crucially, the sale of peat and peat-containing products in the UK. That ensures that peat wouldn’t just get imported from other European countries.

Pilots and progress

The UK government recently announced £3.1m funding for pilot projects to rewet and preserve lowland peat, with peat restoration seen as a cornerstone of net zero ambitions. This campaign calls for further acceleration of peatland restoration across the UK.

As a research of the science behind peatland restoration, I see firsthand the enormous effort involved in this: the installation of dams to block old agricultural drainage ditches, the delicate management of water levels and painstaking monitoring of the peat wetness.

I spend a lot of time taking samples, monitoring the progress, feeding results back to the land managers. Like many other conservationists, I work hard to find ways to preserve these critical habitats.

But sometimes, there may be a digger in the adjacent field doing more damage in a day than we could undo in a lifetime. That’s the reality, and the insanity, of the UK’s current peatland policies.

We heavily invest in restoring peatlands, yet fail to ban its extraction – the one action that would have the most dramatic impact. By demanding that peat is not only eradicated from garden compost, but weeded out of our supply chains, we can keep peat in the ground, not in pots.

Why are neonicotinoids so polarised?

Bee on yellow flower

The use of neonicotinoid insecticides has been, and still is, a topic of huge controversy and dispute. To use an appropriate analogy, stakeholders appear to fall into one of two neighbouring fields, distinctly fenced off from one another.

In one field, there are those that believe that the scientific evidence revealing the impacts of neonicotinoid compounds on pollinators and the wider environment is more than sufficient to strictly ban their use as a pest management tool. In the other field, interested parties argue that the evidence is convoluted and context specific, and that in some circumstances neonicotinoid use can be a safe, and environmentally resourceful strategy.

But why has this topic become so polarised? And why is there increasingly less space for those that wish to ‘sit on the fence’? This blog summarises the research published in a recent paper by Hannah Romanowski and Lauren Blake. The paper investigates the causes of controversy, and analyses the viability of alternatives in the UK sugar beet system.

What are neonicotinoids?

Neonicotinoids (neonics) are a group of synthetic compounds used as the active ingredient in some insecticides. They are neuroactive, which means that they act on the nervous system of the insect, causing changes in behaviour. They specifically bind to receptors of the nicotinic acetylcholine (nAChRs) enzyme, which are specific to insects, meaning neonics have low toxicity to vertebrates, such as mammals. They are used to control a variety of pests, especially sap-feeding insects such as aphids. Neonics are a systemic pesticide, meaning that they are absorbed by the whole plant (either by seed coating or spraying) and distribute throughout all the plants tissue.

Are neonics legal in the UK?

That’s where things get confusing… the answer is both yes and no. In 2018, the UK prohibited the outdoor use of neonics following a review of the evidence about their risk to pollinators, published by the European Food Safety Authority. However, the UK and many other EU member states have since granted emergency authorisations, which allows the use of neonics under a set of specific circumstances and conditions. The best-known example of this in the UK is the emergency authorisations granted in 2021, 2022 and 2023 for the use of thiamethoxam, one of the banned neonicotinoid compounds, on sugar beet.

However, even if an emergency authorisation is approved by UK Government, the predicted virus incidence (forecasted by Rothamsted Insect Survey) in a given year must be above a decided threshold before authorisation is fully granted. If the threshold is not met, neonicotinoids use remains prohibited. In 2021 for example, Defra set the threshold at 9%, and since the forecast of the virus was only 8.37%, the neonicotinoid seed treatment was not used. The crop went on to grew successfully unscathed by the virus.

Why is sugar beet an exception?

The Expert Committee on Pesticides (ECP) produced a framework in 2020 that laid out a list of requirements for an emergency authorisation of a prohibited pesticide. Requirements include not having an alternative, adequate evidence of safety, limited scale and control of use, and evidence of a permanent solution in development. In essence, the long-term economic and environmental benefits of granting the temporary emergency authorisation must outweigh any potential adverse effects resulting from the authorisation.

Sugar beet is extremely vulnerable to a yield-diminishing group of viruses known as yellows virus (YV). YV are transmitted by an aphid vector, Myzus persicae, which are effectively controlled by neonic seed treatment. Compared to other crop systems, sugar beet is also considered low risk and ‘safer’ as it does not flower before harvest and is therefore not as attractive to pollinator insects. As was found during the research of this paper, there are currently no alternatives as effective as neonics in this system, but long-term solutions are in development. Since sugar beet produces 60% of white sugar consumed in the UK, the economic and environmental impacts of yield loss (i.e. from sugar imports) would be serious. In 2021, the government felt that sugar beet sufficiently met the requirements outlined by the ECP, and emergency authorisation was granted.

What were the aims of this paper?

The main aim of this study was to identify the key issues associated with the debate surrounding the emergency authorisation of neonics on sugar beet, and evaluate and compare current policy with potential alternatives.

Most of the data for this study was collected through semi-structured interviews with nine respondents, each representing a key stakeholder in this discussion. Interviews took place in 2021, just after the announcement that neonics would not be authorised, despite granting the emergency authorisation, as the threshold was not met.

What did this research find?

The main take-home from this research was that uncertainty around the scientific evidence was not the biggest concern to respondents, as was predicted. Instead, respondents were alarmed at the level of polarisation of the narrative.  It was broadly felt that the neonicotinoid debate illustrates the wider issues around environment discussions, that are falsely perceived as a dichotomy, fuelled by media attention, and undermining of science.

The organisation of the sugar beet industry was also considered an issue. In east England, where sugar beet is grown, local growers supply only one buyer, British Sugar. This means that for British Sugar to meet demand they use a contractual system, whereby growers are contracted each year to meet a particular yield. This adds pressure to growers, and means that British Sugar controls the seed supply and therefore the treatment of seeds with synthetic pesticides. One respondent in the study said, “At one time you couldn’t order seed that wasn’t treated with neonicotinoid’.

The study also found that alternatives such as Integrated Pest Management (IPM) and Host Plant Resistance (HPR) were not yet effective in this system. There were 3 reasons why IPM fails. Firstly, sugar beet has a very low yield diminishing threshold for the virus, meaning that it does not take much infection to significantly effect yield. Secondly, the system is extremely specific, meaning that general IPM practices do not work and research on specific methods of IPM (such as natural predators of Myzus persicae) are limited. HPR is in development, and some new varieties of plant with host resistance have been produced, but the virus has multiple strains and no HPR varieties are resistant to all of them. Finally, there is no incentivisation for farmers to take up alternative practices. Due to the contract system, the risk to growers of sugar beet to try new pest management strategies is too high.

What is the latest in 2023?

In 2023, another emergency authorisation was granted, however the threshold set by Defra was increased to 63% virulence. In March, the Rothamsted Virus Yellows forecast predicted an incidence of 67.51%, and so the neonicotinoid seed treatment was used. With this authorisation there are still conditions that growers are required to meet to mitigate any risk to pollinators. This includes no flowering crops being grown for 32 months after neonic treated sugar beet has grown, using herbicides to reduce the number of flowering weeds that may attract pollinators to the field growing treated sugar beet, and compliance with stewardship schemes such as monitoring of neonicotinoid residues in the environment.

Degrowth isn’t the same as a recession – it’s an alternative to growing the economy forever

lovelyday12/shutterstock

The UK economy unexpectedly shrank by 0.3% in March, according to the Office of National Statistics. And though the country is likely to narrowly avoid an official recession in 2023, just as it did the previous year, the economy is projected to hit the worst growth rates since the Great Depression, and the worst in the G7.

For many people, this certainly feels like a recession, with food prices soaring and pay falling dramatically below inflation meaning many people are having to reduce their standard of living.

Against this backdrop, the main political parties are focused on delivering economic growth for a better future. One of Prime Minister Rishi Sunak’s five priorities for 2023 is simply “growing the economy”, while opposition leader Keir Starmer has pledged to turn the UK into the fastest growing G7 economy.

Sunak and Starmer’s priorities reflect conventional economic wisdom that “growth, growth, growth” increases incomes and standards of living, employment and business investment. When the economy doesn’t grow, we see unemployment, hardship and inequality.

Growth cannot solve everything

However, economic growth on its own is not going to solve these multiple and intersecting crises, as it only counts the total value of goods and services produced without measuring qualitative change – whether this stuff makes you feel happy or secure.

GDP measures things not feelings.

In contrast, an increasing number of policymakers, thinkers and activists argue for abandoning our obsession with growth at all costs. Instead of pursuing GDP growth, they suggest orienting the economy towards social equality and wellbeing, environmental sustainability and democratic decision making. The most far reaching of those proposals are made under the umbrella term of degrowth.

Degrowth is a set of ideas and a social movement that presents a comprehensive solution to these issues. The pandemic demonstrated that a new normal can be achieved at pace, as we saw sweeping changes to how many of us lived, worked, and travelled.

At the time, headlines equated the pandemic-related GDP squeeze with the perceived “misery of degrowth”. With persistently high inflation rates and the cost of living still spiralling, these debates are going to resurface.

Degrowth is not the same as shrinking GDP

To begin with, degrowth is not the same as negative GDP growth. Instead, degrowth envisions a society in which wellbeing does not depend on economic growth and the environmental and social consequences of its pursuit. Degrowth proposes an equitable, voluntary reduction of overconsumption in affluent economies.

Equally important is to shift the economy away from the ecologically and socially harmful idea that producing more stuff is always good. Instead, economic activity could focus on promoting care, cooperation and autonomy, which would also increase wellbeing and give people a bigger say in how their lives are run.

Yet, for many people the word smacks of misery and the type of frugality they are trying to escape from during the cost of living crisis.

But degrowth, if successfully achieved, would arguably feel better than a recession or a cost-of-living crisis. Here are three reasons why:

1. Degrowth is democratic

The first is the undemocratic and unplanned nature of a recession or cost-of-living crisis. Most citizens would agree, for example, that they had little to no control over the deregulation of the finance industry, and subsequent boom in sub-prime mortgage lending and derivatives trading that caused the 2008/09 financial crash.

Degrowth, on the other hand, is a profoundly democratic project. It emphasises direct democracy and deliberation, which means citizens can shape which economic sectors are decreased and by how much, and which ones will grow and by how much.

One example of such a democratic endeavour is the Climate Assembly UK, whose 108 members were selected through a civic lottery process and were broadly representative of the population. After listening to expert testimony, the assembly issued a number of recommendations to support the UK’s net zero climate target. Over a third of all members prioritised support for sustainable growth. Economic growth itself was not among the top 25 priorities.

2. Degrowth would be egalitarian

Recessions, especially when coupled with fiscal austerity, tend to amplify existing inequalities by hitting the poorest members of society first, including women, working-class communities and ethnic minorities.

Degrowth drastically differs from a recession because it is a redistributive project. For instance, a universal basic income), an unconditional monthly state payment to all citizens, is a popular policy with degrowthers.

The degrowth vision is that basic income should guarantee a dignified living standard, remunerate unpaid care, and provide access to healthcare, food and accommodation for those in need. It could be financed by “climate income” schemes that tax carbon and return revenues to the public.

3. Degrowth wouldn’t hinder climate action

In an economy reliant on growth, a recession is generally bad news for the environment.

For instance, for the UK to hit its net zero targets, it must make annual public investments of between £4 billion and £6 billion by 2030. A recession would threaten public spending as well as the confidence investors have in low carbon developments in transport, housing or energy.

But such investments do not have to depend on growth but could instead be made through collective and democratic decisions to make climate action a priority. Carbon taxes will play a large part in this, as will stopping fossil fuel subsidies like the £3.75 billion tax break granted to develop the Rosebank oil and gas field in the sea north of Scotland.

To make sure we stay within the environmental limits within which we can safely operate, sometimes known as our planetary boundaries, degrowth suggests democratically establishing limits on resource use. For example, global greenhouse gas emissions or non-renewable energy use could be capped at a given level, and decline annually.

Sharing these resource “caps” among the population would ensure that while we stay within these safe environmental spaces, everyone has equitable access to the resources required to lead a fulfilling life. In contrast to the pursuit of endless growth, degrowth puts both climate action and human wellbeing at its heart.The Conversation

Seasonal Worker visa route encounters problems

apples and plums

Radio 4 interview with Dr Lydia Medland

Following the Home Office revocation of the license of one of the seasonal agricultural worker recruitment operators, Dr Lydia Medland spoke to BBC farming today on 20th February 2023 about the scheme (listen here).

The UK Seasonal Worker visa route allows workers to come from around the world to work for up to six months. There are (or were) seven ‘operators’ of the scheme. These are licenced by the government as the recruiters and sponsors of the workers and are responsible for both enforcement of the scheme requirements, particularly ensuring that workers go home at the end of their stay, and for worker protection.

The UK has had some form of seasonal worker migration scheme since the end of World War II, but the current scheme dates from 2019, when following Brexit, EU workers no longer had access to the UK labour market, and UK fruit and vegetable growers and food producers had to look elsewhere to fill seasonal labour vacancies.

At the end of 2021, Dr Medland and Dr Scott (University of Gloucestershire) wrote a briefing outlining problems in the design of the scheme recommending major changes including a guaranteed minimum income, and for workers to have full access to public services.

In her interview with Radio 4 on 20th February Dr Medland spoke of her concerns that the same companies are responsible for ensuring workers’ return as are responsible for preventing their exploitation, saying that with ‘…outsourcing to for-profit businesses of this dual very important role, it isn’t surprising that something has gone wrong, I think the UK should go back to the drawing board on this scheme.’ Academic research has found (see for example Costello and Freedland, 2014) that where there is an interaction between protection of workers and enforcement of migration law, the enforcement role takes precedence. This leaves workers vulnerable to exploitation because they fear the same organisations and laws that are also meant to protect them.

Radio 4 put these comments to the Home Office who said, ‘The seasonal workers route has been running for three years and each year there have been improvements.’ However, the increasing scrutiny of the scheme by researchers, NGOs and journalists may be having some impact because on 23rd February 2023 Mark Spencer, the Farming Minister announced that Seasonal Workers coming to the UK on the scheme would be guaranteed 32 hours a week of work. This is in response to reports that workers are returning in debt because of there is less work than originally expected.

Whilst the Seasonal Workers visa route is no longer officially a ‘pilot’ it has only been renewed until the end of 2024 and it remains open to significant review. This policy is part of the focus of the ‘Working for 5 a day’ project because seasonal migrant workers are a vital part of the labour force that ensures consumers have access to fruit and vegetables. We will continue to follow this policy development and its changing context.

The Horn of Africa has had years of drought, yet groundwater supplies are increasing – why?

 

Harvepino / shutterstock

The Horn of Africa – which includes Somalia, Ethiopia, Kenya and some surrounding countries – has been hit by increasingly frequent and devastating droughts. Despite this, it seems the region has an increasing amount of groundwater. And this water could help support drought-stricken rural communities.

That’s the key finding from our new research, in which we discovered that while overall rainfall is decreasing, an increase in “high-intensity” rainfall has led to more water being stored deep underground. It’s a paradoxical finding, yet one that may help one of the world’s most vulnerable regions adapt to climate change.

In the Horn of Africa, rural communities live in a constant state of water scarcity punctuated by frequent periods of food insecurity. People there rely on the “long rains” between March and May and the “short rains” between October and December to support their lives and livelihoods.

As we write this, the region’s drylands are experiencing a fifth consecutive season of below-average rainfall. This has left 50 million people in acute food insecurity. The droughts have caused water shortages, livestock deaths, crop failures, conflict and even mental health challenges.

The drought is so severe that it is even affecting zebras, giraffes and other wildlife, as all surface waters are drying up and edible vegetation is becoming scarce. Worryingly, a sixth failed rainy season has already been predicted for March to May 2023.

Long rains down, short rains up

In a new paper we investigated changes in seasonal rainfall in the Horn of Africa over the past 30 years. We found the total rainfall within the “long rains” season is declining, perhaps related to the warming of a particular part of the Pacific Ocean. However, rainfall is increasing in the “short rains”. That’s largely due to a climate phenomenon known as the Indian Ocean Dipole, when a warmer-than-usual Indian Ocean produces higher rainfall in east Africa, similar to El Niño in the Pacific.

We then investigated what these rainfall trends mean for water stored below ground. Has it decreased in line with declining “long rains”, or risen due to the increasing “short rains”?

To do this we made use of a pair of satellites which orbit repeatedly and detect small changes in the Earth’s gravitational field that can be interpreted as changes in the mass of water storage. If there’s a significant increase in water storage underground, then the satellite will record a stronger gravity field at that location compared to the previous measurement, and vice versa. From this, the mass of water added or lost in that location can be determined.

Using these satellite-derived estimates, we found that water storage has been increasing in recent decades. The increase correlates with the increasing “short rains”, and has happened despite the “long rains” getting drier.

Given that the long rains deliver more seasonal rain than the short rains, we wanted to understand the paradoxical finding that underground water is increasing. A clue is given by examining how rainfall is converted into groundwater in drylands.

When rain is light and drizzly, much of the water that reaches the ground dampens the soil surface and soon evaporates back into the warm, dry atmosphere. To become groundwater, rainfall instead needs to be intense enough so that water will quickly infiltrate deep into the soil. This mostly happens when lots of rain falls at once and causes dry riverbeds to fill with water which can then leak into underground aquifers.

These most intense rainfall events are increasing in the “short rains”, in line with the overall increase in total rain in that season. And despite a decrease in overall rainfall in the “long rains”, intense rainfall has remained consistently high over time. This means that both rainy seasons have enough intense rainfall to increase the amount of water stored underground.

Finally, we demonstrated that the increasing water storage in this region is not connected to any rise in soil moisture near the surface. It therefore represents “banked” water that resides deep below ground and likely contributes to a growing regional groundwater aquifer in this region.

Groundwater can help people adapt to climate change

While early warning networks and humanitarian organisations focus on the urgent impacts of drought, our new research points to a silver lining that may support long-term climate adaptation. Those rising groundwater supplies we have identified may potentially be exploited to support people in rural areas whose food and water are increasingly insecure.

But there are some caveats. First, we have not assessed the depth of the available groundwater across the region, but we suggest that the water table is shallow enough to be affected by seasonal rainfall. This means it may also be shallow enough to support new bore holes to extract it. Second, we do not know anything about the quality of the stored groundwater and whether it can be deemed suitable for drinking. Finally, we do not know exactly what will happen if the most extreme droughts of the past few seasons continue and both long and short rains fail, causing intense rainfall to decrease too.

Nevertheless, our findings point to the need for extensive groundwater surveys across the Horn of Africa drylands to ascertain whether this increasing water resource may be viable enough to offset the devastating droughts. Groundwater could potentially irrigate fields and provide drinking water for humans and livestock, as part of a strategy to help this vulnerable region adapt to the effects of climate change.The Conversation

Foodie for thought

Have you ever wondered how the food you eat impacts climate change? There are all sorts of discussions around energy, transport, green tech, that famous 1.5 ℃, the IPCC… but there is a significantly unspoken polluter that is part of our daily lives, and without which, ironically, we could not live: the food industry. The food industry is one of the biggest contributors to climate change and biodiversity loss, yet food systems have not been given much thought until recently, somehow it was always thought that food “just happens”.

How many of us, when shopping at the supermarket, really think about where everything that is there, nicely placed on the shelves and aisles, comes from? Who packaged your apples? Who flew your avocados from Brazil? Who harvested those avocados from Brazil and how much were they paid? How old was that cow that some factory milked, and who bottled the milk? What is the footprint of that bottle? How much space do cows take? How much soya do they need to grow? How much do cows emit? We could go on forever, but the reality is that not many people really ask those questions at the supermarket, for some, as I said, food happens.

And I feel obliged here to open a short bracket to say that, of course, in reality there will be people who are not even able to ask those questions because it is not their priority. There are often bigger problems in our lives we have to deal with, and it would be unreasonable to ask people who, for example, are struggling to make ends meet to think about what they buy. But on the other hand that is also the point. We have made it incredibly difficult and almost a privilege for people to be able to reflect on their food. So returning to my initial point, how could we blame anyone for not asking all those questions, when we have become so detached from those very people who produce our food, and those places where food is grown?

With food systems becoming ever more complex and globalised, individuals started to lose touch with the reality behind the curtains. We no longer ask the farmer; we ask the label, but how much can a label tell us about what we are buying? Unfortunately, big corporations can often hide behind labels, something that we now call “green-washing”, a fancy word for misleading (and often false) advertising that creates nothing but confusion among consumers, making them believe that they are making a conscious and environmentally friendly choice, when they are not.

One of the biggest controversies in the past few years was around the MSC (Marine Stewardship Council) “Certified Sustainable Seafood” label (that blue tick on tuna cans and other fish sold in supermarkets), which was criticised for setting a very low bar for fisheries to be certified as sustainable, and for its lack of on-site controls and checks. So not only the label allegedly does not guarantee that all efforts have been made to avoid bycatch and seabed damage, but also the fact that fisheries buy the certification from the MSC is for many something that undermines its credibility.

So how can consumers navigate all this information? It would be impossible for people to be able to assess the credibility of every label, stamp, tick on their food, but also unreasonable. The lack of transparency in the food system we are locked-in is a massive flaw, and labels, the way they are handed out now, are not a solution.

There has been much talk about reconnecting with our producers through smaller supply chains, and the idea of buying from their local farmers is something that many probably dream of. How nice would it be to just go to the local market, like the good old days, and buy fresh fruit, vegetables, fresh meat, fresh eggs… all sorts of delicious, good food? It would be great, yes, but probably a utopia for a long time still. Just think of Bristol, a great city with plenty of good food and farmers, a city that has been recognised for its efforts towards a better food system, yet in 2021 about 6.5% of the local population suffered from hunger and 12% struggled to access food. How is this happening in a city so rich of diverse cuisines?

There are many factors that contribute to the rise of food insecurity in Bristol. Covid-19 and the rise in cost of living are maybe the most obvious and recent factors, but generally any inequality can be linked back to poverty and lack of accessibility (which shockingly is a big problem in Bristol). But aside from all of these, something that has an impact on food systems (much more than what many would think) is culture. Systems are ultimately the result of our own ways of doing, ingrained in practice and often locked in, and our ways of doing are inevitably linked to our culture. Now I will not spend time telling you about the history of our food systems and British food culture, because, as a matter of fact, my point is somewhere else. However, in the past few years we have seen the so-called “foodie culture” emerge.

Being a foodie in the simplest terms means that you care about food and are interested about what you eat and where it comes from, which, don’t get me wrong, it is great! Because these people are probably asking those questions that I mentioned at the beginning. However, the problem is that foodie culture has become a very much elitist trend, and with food becoming more and more trendy and catered for foodies, it has now become acceptable to charge stratospheric prices for a burger and chips because the potatoes are organic. Satire aside, it is true, the quality of products should be valued more, and of course products that are produced more sustainably cost more; but this also means that we are telling people who cannot afford to spend more than a certain amount on a good burger with chips that they cannot eat good food.

The fundamental issue of foodie culture is that it has become a trend to eat “fancy” food, which gives businesses the power to price things up, in a way that it becomes exclusionary for people who do not have the privilege of being able to “treat themselves”, and this creates more division. Unfortunately, foodie culture goes hand in hand with a very much criticised characteristic of environmentalism and sustainable living, which is that it is predominantly a (white) middle-class prerogative. Being able to afford to think about sustainability is a privilege, and of course those who are in such fortunate position have the responsibility to act upon it, but what we should not forget is that indeed we are in a position that many could only envy.

There is no way we can create a better and more transparent food system, where people are connected and aware, if all these inequalities still exist. We cannot have a better food system when we live in a cultural setting that leaves half of the population behind, which is perhaps the main message I want to convey. If you have read this far, I hope you will give more thought to what your standpoint and your privileges are. I do wish I had the answers to all these problems I laid out, but there is only so much one can do in a one-year research programme!

How ancient plants ‘learnt’ to use water when they moved on to land – new research

Focal point/Shutterstock

“Plants, whether they are enormous, or microscopic, are the basis of all life including ourselves.” This was David Attenborough’s introduction to The Green Planet, the latest BBC natural history series.

Over the last 500 million years, plants have become interwoven into every aspect of our lives. Plants support all other life on Earth today. They provide the oxygen people breathe, as well as cleaning the air and cooling the Earth’s temperature. But without water, plants would not survive. Originally found in aquatic environments, there are estimated to be around 500,000 land plant species that emerged from a single ancestor that floated through the water.

In our recent paper, published in New Phytologist, we investigate, at the genetic level, how plants have learnt to use and manipulate water – from the first tiny moss-like plants to live on land in the Cambrian period (around 500 million years ago) through to the giant trees forming complex forest ecosystems of today.

How plants evolved

By comparing more than 500 genomes (an organism’s DNA), our results show that different parts of plant anatomies involved in the transport of water – pores (stomata), vascular tissue, roots – were linked to different methods of gene evolution. This is important because it tells us how and why plants have evolved at distinct moments in their history.

Plants’ relationship with water has changed dramatically over the last 500 million years. Ancestors of land plants had a very limited ability to regulate water but descendants of land plants have adapted to live in drier environments. When plants first colonised land, they needed a new way to access nutrients and water without being immersed in it. The next challenge was to increase in size and stature. Eventually, plants evolved to live in arid environments such as deserts. The evolution of these genes was crucial for enabling plants to survive, but how did they help plants first adapt and then thrive on land?

Stomata, the minute pores in the surface of leaves and stems, open to allow the uptake of carbon dioxide and close to minimise water loss. Our study found that the genes involved in the development of stomata were in the first land plants. This indicates that the first land plants had the genetic tools to build stomata, a key adaptation for life on land.

The speed in which stomata respond varies between species. For example, the stomata of a daisy close more quickly than those of a fern. Our study suggests that the stomata of the first land plants did close but this ability speeded up over time thanks to gene duplication as species reproduced. Gene duplication leads to two copies of a gene, allowing one of these to carry out its original function and the other to evolve a new function. With these new genes, the stomata of plants that grow from seeds (rather reproducing via spores) were able to close and open faster, enabling them to be more adaptable to environmental conditions.

Old genes and new tricks

Vascular tissue is a plant’s plumbing system, enabling it to transport water internally and grow in size and stature. If you have ever seen the rings of a chopped tree, this is the remnants of the growth of vascular tissue.

We found that rather than evolving by new genes, vascular tissue emerged through a process of genetic tinkering. Here, old genes were repurposed to gain new functions. This shows that evolution does not always occur with new genes but that old genes can learn new tricks.

Before the move to land, plants were found in freshwater and marine habitats, such as the algal group Spirogyra. They floated and absorbed the water around them. The evolution of roots enabled plants to access water from deeper in the soil as well as providing anchorage. We found that a few key new genes emerged in the ancestor of plants that live on land and plants with seeds, corresponding to the development of root hairs and roots. This shows the importance of a complex rooting system, allowing ancient plants to access previously unavailable water.

The development of these features at every major step in the history of plants highlights the importance of water as a driver of plant evolution. Our analyses shed new light on the genetic basis of the greening of the planet, highlighting the different methods of gene evolution in the diversification of the plant kingdom.

Planting for the future

As well as helping us make sense of the past, this work is important for the future. By understanding how plants have evolved, we can begin to understand the limiting factors for their growth. If researchers can identify the function of these key genes, they can begin to improve water use and drought resilience in crop species. This has particular importance for food security.

Plants may also hold the key to solving some of the most pressing questions facing humanity, such as reducing our reliance on chemical fertilisers, improving the sustainability of our food and reducing our greenhouse gas emissions.

By identifying the mechanisms controlling plant growth, researchers can begin to develop more resilient, efficient crop species. These crops would require less space, water and nutrients and would be more sustainable and reliable. With nature in decline, it is vital to find ways to live more harmoniously in our green planet.The Conversation

Urban gardens are crucial food sources for pollinators – here’s what to plant for every season

Pollinators are struggling to survive in the countryside, where flower-rich meadows, hedges and fields have been replaced by green monocultures, the result of modern industrialised farming. Yet an unlikely refuge could come in the form of city gardens.

Research has shown how the havens that urban gardeners create provide plentiful nectar, the energy-rich sugar solution that pollinators harvest from flowers to keep themselves flying.

In a city, flying insects like bees, butterflies and hoverflies, can flit from one garden to the next and by doing so ensure they find food whenever they need it.
These urban gardens produce some 85% of the nectar found in a city. Countryside nectar supplies, by contrast, have declined by one-third in Britain since the 1930s.

Our new research has found that this urban food supply for pollinators is also more diverse and continuous throughout the year than in farmland. Everyone with a garden, allotment or even a window box can create their own haven for pollinators. Here are tips on what to plant for each season.

What to plant in spring

The first queen bumblebees emerge from winter hibernation in February and March. They need food straight away.

At this time of year nectar-rich plants are vital energy sources for warming up cold flight muscles, with pollen providing the necessary protein for egg laying and larval growth. In early spring much of the countryside is still bleak and inhospitable.

Gardeners can help by planting borders of hellebore, Pulmonaria and grape hyacinth. Trees and shrubs such as willow, cherry and flowering currant are also fantastic for packing a lot of food into a small space.

What to plant in summer

In late spring and early summer, pollinators have more food available – but there is also more competition for it. So it is crucial to ensure you have a diverse array of different flowering plants. This will guarantee there is attractive and accessible food to suit a wide range of insects and provide them with nutritionally balanced diets.

A great assortment of plants, including honeysuckle, Campanula and lavender, can provide floral resources in summer. Mowing the lawn a little less often will help too, giving the chance for important so-called weeds, such as clover and dandelion, to bloom.

What to plant in autumn

By late summer and autumn there are fewer species still flowering in gardens. A handful dominate the nectar supplies, particularly Fuchsia, Salvia and Crocosmia.

For many pollinators, however, these flowers are entirely useless. Their nectar is hidden away down a tube, only accessible to insects with long tongues, such as the garden bumblebee.

This means solitary bees and hoverflies may need to find other sources of food. The gardener can help by prioritising open and accessible flowers. Opt for species such as ivy, Sedum, Echinacea and oregano.

What to plant in winter

Few pollinators are still active in winter. Most species die off leaving the next generation behind as eggs, larvae or pupae.

But bumblebees and honeybees remain in flight, taking advantage of the warmer climate and winter flowers that cities can provide. By vibrating their wings, bumblebees can warm up to forage in temperatures barely exceeding freezing point, but they need a lot of energy-rich nectar to do so. If you want to attract bees into your garden during the winter some of the best options are Mahonia, sweet box, winter honeysuckle and the strawberry tree.

Urban gardens are small and numerous, with hundreds or even thousands packed into a single square kilometre of a residential neighbourhood. Each gardener is different, with individual preferences of what to plant, how regularly to mow the lawn and even how to decide what constitutes a weed.

This results in an enormous variation from garden to garden in the quantity of nectar, the timing of its production and the types of flowers producing it. But there is always room for improvement. Some gardens provide pollinators with hundreds of times less nectar than others.

So keep yours well stocked with nectar and free from toxic pesticides. You’ll be amazed by the impact you can have.

Who’s at the table? Priorities after a year of food justice dialogue

Defining ‘Food Justice’ is not easy. When it comes to ‘fairness’ and ‘equality’ in relation to our food system, should we be concerned with questions of individual citizens’ access to sustainable sources of subsistence, or issues of production, labour and the practices of agri-business? Do people have clear rights to food? And should such rights focus on quantity alone, or take account of the quality and nature of food? Furthermore, when defining ‘food justice’ should we be primarily concerned with human rights, or are we dealing with complex systems that oblige us to think about non-human persons and actors, including animals and the environment? Whatever our responses to these questions might be, it seems clear that thinking about climate change cannot ignore either food or justice.

An artistic collaboration is stimulating discussion about who is at the table in (un)just food systems.

Over the last year, we have established the Bristol Researchers Food Justice Network. Primarily, this has been through setting up a regular fortnightly seminar series, a workshop exploring the core purpose, values and potential for the Network, and an artistic collaboration to experiment with interactive ways of thinking about the food system and food justice. As it moves into its second year, we reflect on some of the key themes discussed so far. Recent models suggest that policy decisions that focus on climate alone will likely result in rapid growth in social inequalities, including and especially in the global food system. As we focus on questions of environmental sustainability and climate change in the light of the Cop-26 conference, some key food justice issues come to mind:

1. The way that we see food justice is systemic, equally as environmental as it is social

Every part of the food system is connected. Problems with diet are not disconnected to labour force, or price of food, or access to land, or environmentally sustainable farming. It is possible to have a food justice perspective towards understanding food systems. This involves seeing and considering people and other beings everywhere in the system and their being recognised as having an inherent value, with such value not being cheapened in the name of economic cost.

What clearly emerged from the network workshop, which involved researchers from vets to social scientists, historians and lawyers, was that we valued word and concept of ‘justice’ because it captures the common understanding that we are committed to change where we see injustice. While many network members understand food interactions as part of a ‘food system’, the concept of justice helps us maintain a critical and action-led approach where we see problems in those food systems.

2. Justice in food systems is bound up with structures of trade and foreign policy agendas

Since the mid-nineteenth century, Britain has largely relied on food imports, a model which has today become normalised. For many, changing this model is fundamental to building a more sustainable food system. But this cannot be a choice between either climate or society Recent government initiatives promise radical new directions in agriculture policy but keep this trade-centred model intact. Thus, the UK is determined to get farmers away from food subsidies, having committed to end direct payments by 2027. This would turn farmers into environmental stewards whilst offshoring the production of food elsewhere. Moreover, trade deals can increasingly be seen to trade away local and national food production in favour of other priorities, something that the network held a ‘policy hack’ discussion about following the approval of the UK-Australian Free Trade deal in June 2021.

Lauren explores how the table at the heart of the artistic collaboration is supported and wired together.

3. The Dutch model alone cannot save the world

Many models for the future of farming, food supply and food consumption, focus on technical solutions. Accounts of the ‘miracle’ of Dutch agriculture, for example, cite the emphasis on the investment in research and innovation that have underpinned the country’s apparent success in agricultural research and development. But what are the social implications of technological solutions – and what if we end up sacrificing quality for efficiency?

Will research led by agri-food corporations underpin a genuine revolution in global food production, or create intellectual property that marginalises small-scale and community-centred farming enterprises in ecologically-vulnerable territories in the Global South? Some agri-tech policies pioneered by countries such as the Netherlands – such as responsible antibiotic use – are to be lauded, but if these are pursued in the service of intensive agriculture, real problems remain.

4. Consumers are key to change – but we need to do more than blame and shame

As individual consumers, we all have a role to play in transforming the food system; but individualising systemic problems simply places the onus on the consumer in ways that often inhibit radical action. Moreover, as recent polling suggests, individuals are reluctant to embrace environmental actions – such as reducing meat consumption – that have the greatest impact on their own lives.

The choices we make certainly matter, but the notion of ‘choice’ is in many cases an illusory, erroneous and pernicious concept. In effect, consumers  are presented as ‘both the cause and the solution to potential health problems and thus are made to be accountable for their own health.’ This is especially true when we consider questions of poverty and its relation with obesity and other diet-based non-communicable disease. The idea that consumers, by choosing to consume ‘ethically’, ‘sustainably’ or ‘healthily’ can on their own resolve social and environmental deep-seated problems. Policies that place the responsibility for making healthy, ethical and sustainable food choices on individuals fail to address the contexts in which individuals and families live and work.

5. Agriculture and the people within it are being consistently undervalued, around the world

The current food system involves at least 1.1 billion people working in agriculture, who are often among the world’s poorest people. Peasant and self-sufficient farming practices, which often involve very low carbon emitting practices are routinely undermined by large infrastructure and deforestation practices, perpetuating a cycle of the mobility of people away from the agricultural sector that does not compensate them well (including through low international prices for primary agricultural products) towards more intensive practices in the same sector, or into other types of work.

Intensive agriculture relies on a waged labour force of 300-500 million, including many who depend on jobs in plantation work, which is degrading and, in some cases, involves forced labour and modern slavery, having emerged from systems of production developed under conditions of colonial slavery, such as in sugar plantations. Meanwhile, migrant workers make up a large proportion of seasonal and harvest workers in many rich countries because they are in a weak position in the labour force and are therefore, overall, are paid lower wages and offered poorer conditions than their national counterparts. Small producers across the world attempting to live in low-impact lifestyles are usually excluded from subsidies, but often even wealthy farmers, find their land crops and livestock are undervalued. To stay in the sector people working within it are frequently pushed into other activities to diversify and supplement their livelihoods through ecotourism or other specialised initiatives drawing income from the service sector. Why isn’t there inherent value to producing food?

6. The combined challenges of climate and biodiversity crisis for agriculture must be addressed as issues of food justice

A (contested) narrative is emerging that suggests it is possible to divide the world into areas which protect nature and areas which intensively produce food but have negative environmental consequences. We are thus presented with ‘difficult choices’ premised on the belief that farming is inherently incompatible with conservation and climate change mitigation.

This is an off-setting approach which uses a logic of ecological destruction in one place to be compensated for by nature promotion/restoration in another place. However, such ‘land sparing’ approaches simply maintain the status quo and distract our attention from the root causes of a problematic food system. We should be wary of policies that further outsource food production (and environmental damage) to prioritise environmental conservation/restoration in the UK and elsewhere.

Lead artist and ceramicist, Amy Rose, considers the dynamics present at the table. The collaboration is supported by the Brigstow Institute of the University of Bristol.

These represent some of the central issues we have begun to tackle in the Food Justice Network. As researchers, we also recognise that to fully address concerns around our contemporary food system, we need processes that expand our conversation, allow everyone to tell their stories and to fully engage all our senses. Working with artists and creative practitioners has started to help us broaden and clarify our definitions of food justice and will give us opportunities to engage and interact between and beyond the boundaries of research, public knowledge, and practice.

Creative practice and public engagement can become critical tools as we address the twin challenges of climate emergency and social inequality and their radical impact on our food systems – at local, national, and global scales. Above all, an  emphasis on food justice will be imperative if we wish to develop food policies that sustain both our environmental and human futures. Our current food system embodies historical systemic inequalities that reflect the diverse legacies of colonialism, industrialization, and globalization; these must be addressed rather than amplified in our responses to the climate emergency.
