Why are neonicotinoids so polarised?

Posted on June 22, 2023 by amanda.woodman-hardy

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.

Arctic Ocean could be ice-free in summer by 2030s, say scientists – this would have global, damaging and dangerous consequences

Posted on June 8, 2023 by amanda.woodman-hardy

The Arctic Ocean could be ice-free in summer by the 2030s, even if we do a good job of reducing emissions between now and then. That’s the worrying conclusion of a new study in Nature Communications.

Predictions of an ice-free Arctic Ocean have a long and complicated history, and the 2030s is sooner than most scientists had thought possible (though it is later than some had wrongly forecast). What we know for sure is the disappearance of sea ice at the top of the world would not only be an emblematic sign of climate breakdown, but it would have global, damaging and dangerous consequences.

The Arctic has been experiencing climate heating faster than any other part of the planet. As it is at the frontline of climate change, the eyes of many scientists and local indigenous people have been on the sea ice that covers much of the Arctic Ocean in winter. This thin film of frozen seawater expands and contracts with the seasons, reaching a minimum area in September each year.

The ice which remains at the end of summer is called multiyear sea ice and is considerably thicker than its seasonal counterpart. It acts as barrier to the transfer of both moisture and heat between the ocean and atmosphere. Over the past 40 years this multiyear sea ice has shrunk from around 7 million sq km to 4 million. That is a loss equivalent to roughly the size of India or 12 UKs. In other words, it’s a big signal, one of the most stark and dramatic signs of fundamental change to the climate system anywhere in the world.

As a consequence, there has been considerable effort invested in determining when the Arctic Ocean might first become ice-free in summer, sometimes called a “blue ocean event” and defined as when the sea ice area drops below 1 million sq kms. This threshold is used mainly because older, thicker ice along parts of Canada and northern Greenland is expected to remain long after the rest of the Arctic Ocean is ice-free. We can’t put an exact date on the last blue ocean event, but one in the near future would likely mean open water at the North Pole for the first time in thousands of years.

One problem with predicting when this might occur is that sea ice is notoriously difficult to model because it is influenced by both atmospheric and oceanic circulation as well as the flow of heat between these two parts of the climate system. That means that the climate models – powerful computer programs used to simulate the environment – need to get all of these components right to be able to accurately predict changes in sea ice extent.

Melting faster than models predicted

Back in the 2000s, an assessment of early generations of climate models found they generally underpredicted the loss of sea ice when compared to satellite data showing what actually happened. The models predicted a loss of about 2.5% per decade, while the observations were closer to 8%.

The next generation of models did better but were still not matching observations which, at that time were suggesting a blue ocean event would happen by mid-century. Indeed, the latest IPCC climate science report, published in 2021, reaches a similar conclusion about the timing of an ice-free Arctic Ocean.

As a consequence of the problems with the climate models, some scientists have attempted to extrapolate the observational record resulting in the controversial and, ultimately, incorrect assertion that this would happen during the mid 2010s. This did not help the credibility of the scientific community and its ability to make reliable projections.

Ice-free by 2030?

The scientists behind the latest study have taken a different approach by, in effect, calibrating the models with the observations and then using this calibrated solution to project sea ice decline. This makes a lot of sense, because it reduces the effect of small biases in the climate models that can in turn bias the sea ice projections. They call these “observationally constrained” projections and find that the Arctic could become ice-free in summer as early as 2030, even if we do a good job of reducing emissions between now and then.

There is still plenty of uncertainty around the exact date – about 20 years or so – because of natural chaotic fluctuations in the climate system. But compared to previous research, the new study still brings forward the most likely timing of a blue ocean event by about a decade.

Why this matters

You might be asking the question: so what? Other than some polar bears not being able to hunt in the same way, why does it matter? Perhaps there are even benefits as the previous US secretary of state, Mike Pompeo, once declared – it means ships from Asia can potentially save around 3,000 miles of journey to European ports in summer at least.

But Arctic sea ice is an important component of the climate system. As it dramatically reduces the amount of sunlight absorbed by the ocean, removing this ice is predicted to further accelerate warming, through a process known as a positive feedback. This, in turn, will make the Greenland ice sheet melt faster, which is already a major contributor to sea level rise.

The loss of sea ice in summer would also mean changes in atmospheric circulation and storm tracks, and fundamental shifts in ocean biological activity. These are just some of the highly undesirable consequences and it is fair to say that the disadvantages will far outweigh the slender benefits.

Why 40°C is bearable in a desert but lethal in the tropics

Posted on June 2, 2023 by amanda.woodman-hardy

Phew: heat plus humidity can make Bangkok an uncomfortable place in a heatwave.
Pavel V.Khon/SHutterstock

This year, even before the northern hemisphere hot season began, temperature records were being shattered. Spain for instance saw temperatures in April (38.8°C) that would be out of the ordinary even at the peak of summer. South and south-east Asia in particular were hammered by a very persistent heatwave, and all-time record temperatures were experienced in countries such as Vietnam and Thailand (44°C and 45°C respectively). In Singapore, the more modest record was also broken, as temperatures hit 37°C. And in China, Shanghai just recorded its highest May temperature for over a century at 36.7°C.

We know that climate change makes these temperatures more likely, but also that heatwaves of similar magnitudes can have very different impacts depending on factors like humidity or how prepared an area is for extreme heat. So, how does a humid country like Vietnam cope with a 44°C heatwave, and how does it compare with dry heat, or a less hot heatwave in even-more-humid Singapore?

Weather and physiology

The recent heatwave in south-east Asia may well be remembered for its level of heat-induced stress on the body. Heat stress is mostly caused by temperature, but other weather-related factors such as humidity, radiation and wind are also important.

Our bodies gain heat from the air around us, from the sun, or from our own internal processes such as digestion and exercise. In response to this, our bodies must lose some heat. Some of this we lose directly to the air around us and some through breathing. But most heat is lost through sweating, as when the sweat on the surface of our skin evaporates it takes in energy from our skin and the air around us in the form of latent heat.

Take from Buzan and Huber (2020) Annual Review of Earth and Planetary Sciences, Author provided

Meteorological factors affect all this. For example, being deprived of shade exposes the body to heat from direct sunlight, while higher humidity means that the rate of evaporation from our skin will decrease.

It’s this humidity that meant the recent heatwave in south-east Asia was so dangerous, as it’s already an extremely humid part of the world.

The limit of heat stress

Underlying health conditions and other personal circumstances can lead to some people being more vulnerable to heat stress. Yet heat stress can reach a limit above which all humans, even those who are not obviously vulnerable to heat risk – that is, people who are fit, healthy and well acclimatised – simply cannot survive even at a moderate level of exertion.

One way to assess heat stress is the so-called Wet Bulb Globe Temperature. In full sun conditions, that is approximately equivalent to 39°C in temperature combined with 50% relative humidity. This limit will likely have been exceeded in some places in the recent heatwave across south-east Asia.

In less humid places far from the tropics, the humidity and thus the wet bulb temperature and danger will be much lower. Spain’s heatwave in April with maximum temperatures of 38.8°C had WBGT values of “only” around 30°C, the 2022 heatwave in the UK, when temperatures exceeded 40°C, had a humidity of less than 20% and WBGT values of around 32°C.

Two of us (Eunice and Dann) were part of a team who recently used climate data to map heat stress around the world. The research highlighted regions most at risk of exceeding these thresholds, with literal hotspots including India and Pakistan, south-east Asia, the Arabian peninsula, equatorial Africa, equatorial South America and Australia. In these regions, heat stress thresholds are exceeded with increased frequency with greater global warming.

In reality, most people are already vulnerable well below the survivability thresholds, which is why we can see large death tolls in significantly cooler heat waves. Furthermore, these global analyses often do not capture some very localised extremes caused by microclimate processes. For example a certain neighbourhood in a city might trap heat more efficiently than its surroundings, or might be ventilated by a cool sea breeze, or be in the “rain shadow” of a local hill, making it less humid.

Variability and acclimatisation

The tropics typically have less variable temperatures. For example, Singapore sits almost on the equator and its daily maximum is about 32°C year round, while a typical maximum in London in mid summer is just 24°C. Yet London has a higher record temperature (40°C vs 37°C in Singapore).

Given that regions such as south-east Asia consistently have high heat stress already, perhaps that suggests that people will be well acclimatised to deal with heat. Initial reporting suggests the intense heat stress of the recent heatwave lead to surprisingly few direct deaths – but accurate reporting of deaths from indirect causes is not yet available.

On the other hand, due to the relative stability in year-round warmth, perhaps there is less preparedness for the large swings in temperature associated with the recent heatwave. Given that it is not unreasonable, even in the absence of climate change, that natural weather variability can produce significant heatwaves that break local records by several degrees Celsius, even nearing a physiological limit might be a very risky line to tread.

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

Posted on May 24, 2023 by amanda.woodman-hardy

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.

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 Archers’ electric vehicle row shows why rural areas may oppose chargers – but they also have so much to gain

Posted on April 19, 2023 by amanda.woodman-hardy

Long-running BBC radio soap opera The Archers might conjure images of an idyllic country life, but its storylines frequently highlight real tensions in British society.

The series, set in the fictional village of Ambridge, has been criticised in recent years for storylines which supposedly pander to younger listeners or fail to represent rural life accurately. But the Archers has never shied away from environmental issues, from the escapades of eco-warrior Tom Archer in the late 1990s to more recent episodes about soil health.

Lately, Ambridge has been gripped by a campaign to halt the construction of a new electric vehicle charging station, proposed on a parcel of land being sold by David and Ruth Archer – long-running characters at the centre of the series. This has provoked protests, debates about civic duty and police involvement in the rural idyll.

The placards and slogans of local opponents have fused topics of net zero and the energy transition with anxieties about the future of the countryside. What does this storyline tell us about real rural opposition to such changes?

Charging into trouble

The UK government has pledged to phase out the sale of new petrol and diesel cars by 2030. If electric vehicles (EVs) are to replace them, charging infrastructure must be expanded to help people switch.

By some estimates there are over 35,000 active EV charging ports across the UK. The Department for Transport has pledged 300,000 public chargers by 2030 to stop a patchy network of charging points putting some drivers off buying EVs and allay concerns about their potentially shorter driving range.

Infrastructure built to fulfil national commitments to cut emissions will have important local consequences. The concerns voiced in Ambridge might resonate in rural communities playing host to new construction projects which can bring with them increased traffic, noise and damage to the landscape.

When researching opposition to energy infrastructure for a new book, we learned about Littlehampton in Sussex, a seaside town where residents successfully opposed an on-street EV charging scheme. Residents complained about not being consulted beforehand and argued that charging points, built without off-street parking, would draw drivers from elsewhere who would take spaces from them.

Rural communities have also opposed new renewable energy projects, such as solar farms, for their potential disruption or effect on property values. Many who moved to a rural area to enjoy its natural beauty argue that new infrastructure industrialises the countryside.

Finding community support

In The Archers – like in Littlehampton, Sussex – local opposition to new EV charging stations derives from a feeling that something is happening to residents, rather than with or for them. Some Ambridge residents are suspicious of the shell corporation behind the scheme. In real-life Sussex, residents said that they weren’t properly consulted.

Rural opposition is not inevitable, however. With amenities and services often clustered in bigger towns, rural households must travel further to access them, making them particularly vulnerable to rises in the price of petrol or diesel.

This vulnerability has been exacerbated by dramatic cuts to rural bus routes. An analysis by the Guardian found that one in ten routes were axed in 2022, with 42 routes lost from the west of England alone.

Withdrawing public transport funding cuts off rural communities from essential services and friends and family elsewhere. These same communities could benefit the most from an expanded EV charging network.

Some rural communities aren’t waiting for this to happen and have taken to sharing electric cars to fill the gaps left by lost services instead. For example, new EV clubs are being formed in Wales to give people easier access to shared transport.

These schemes ask people to pay an annual membership fee in return for being able to book a car 48 hours in advance. This is helping people get to GP appointments or job interviews.

But while those living in Greater London might access a charging point every mile on average, this number jumps to one every 16 miles in rural areas.

Plugging the gaps

One reason why rural areas are underserved by EV chargers concerns their cost-effectiveness. In areas where there might be less immediate demand, the upfront investment needed to install a charging point will take longer to pay off.

New subsidies and grants could help install more chargers in more places. But it will be necessary to work with communities to prevent conflict.

Despite the uproar in Ambridge, rural areas have a lot to gain from charging infrastructure. Residents will have differing views which planners must address.

Nearly a quarter of people in the UK flush wet wipes down the toilet – here’s why they shouldn’t

Posted on April 19, 2023 by amanda.woodman-hardy

Charlotte Lloyd, University of Bristol

Whether you’re cleaning your house, your car or your child, there are a variety of wet wipes manufactured for the job. Wet wipes are small, lightweight and extremely convenient. They have become a staple in most of our lives, particularly so during and since the COVID-19 pandemic.

But according to Water UK, an organisation representing the water industry, flushing wet wipes down the toilet is responsible for 93% of sewer blockages and costs around £100 million each year to sort out. And the majority of these wipes, about 90%, contain plastic.

Water UK also found that 22% of people admit to flushing wipes down the toilet, even though most of them knew they posed a hazard. And it’s estimated that 300,000 sewer blockages occur every year because of “fatbergs”, with wet wipes one of the main causes.

But it seems wet wipes could soon be banned in England – well, at least the ones that contain plastic – as the government has said it will launch a public consultation on wet wipes in response to mounting concerns about water pollution and blockages. This follows pledges made by major retailers, including Boots and Tesco, to discontinue the sale of such products.

Market projections show that 1.63 million tons of material will be produced in 2023 for wet wipes globally – an industry worth approximately $2.84 billion (£2.04 billion). Though these figures are likely to be on the conservative side as manufacturers increased the production of disinfecting wipes in 2020 during the pandemic – and have remained at the same level since.

Despite the popularity and wide use of wet wipes, not a lot is known about their environmental footprint. This is because manufacturers are not obliged to state what the wipes are made from on the packaging, only the intentionally added ingredients. This creates a challenge for both scientists and consumers alike.

What we know

Wet wipes are made from non-woven fibres that are fused together either mechanically or with the aid of chemicals or heat. The individual fibres can be made from either natural (regenerated cellulose or wood pulp) or petroleum-based (plastic) materials, including polyester and polypropylene.

Most wet wipes are a mixture of natural and synthetic fibres – and the majority contain plastic. As well as the fibres, wet wipes also contain chemicals, including cleaning or disinfecting agents which are impregnated into the material.

Some wipes are designed to be “flushable” and contain chemical binding agents that are designed to release the fibres of the wipe when they are exposed to water. This means that if wipes are not disposed of correctly, they can create both a plastic and a chemical hazard to the environment.

It’s well known that plastic breaks down extremely slowly and persists for centuries in landfill. And if plastic-containing wipes are released into the environment – either through littering or via the sewerage system – they can pose a number of hazards.

The plastic problem

When wet wipes reach the environment – including soil, rivers and the ocean – they generate microplastic pollution in the form of microfibers. Microfibers are one of the most prevalent types of plastic pollution in the aquatic environment and affect ecosystems as well as potentially human health through their introduction into the food chain.

The problem has been exacerbated by these “flushable” wipes. One study identified seven different types of plastics as potential components of flushable wipes – meaning that they still risk being a source of microplastic pollution. Recent work has confirmed that wet wipes (along with sanitary products) are an underestimated source of white microfibers found in the marine environment.

Data on the environmental impact of the associated chemicals is lacking, but this is something my research group is currently working on. What is known though is that plastics have the ability to absorb other contaminants such as metals and pesticides as well as pathogens. And this provides a way for pollution to be transported large distances through the environment.

Driven by environmental concerns as well as impending legislation, many plastic-free wipe products are now available or being developed. But even products made from natural fibres can still pose a problem to sewerage systems and so safe disposal – in a bin – is key.

The scientific evidence surrounding the environmental effects of bio-based plastics (plastics made from non-petroleum sources such as corn or potato starch) is also lacking, so caution is needed when thinking about simply switching from petroleum-based to bio-based plastics.

With this in mind, reusable washable products are a great alternative to disposables and have a much smaller environmental footprint. They are particularly handy around the home when washing is convenient.

That said, there will remain a market for disposables, but manufacturers should have to clearly label what the wipes are made from so that consumers can make a more informed choice.

What it means to be of the mountains: ethnography of social embrace in Nivica, Albania

Posted on March 31, 2023 by amanda.woodman-hardy

In 2022, I made my fifth visit to the village of Nivica in the heart of the Kurvelesh mountainscape. It was a quick trip for lunch and to say hello to the community that has made me welcome there since 2017. Upon visiting the house of the first couple who hosted me, I was greeted with hot tea, sharp raki and sweet cakes. The older couple, Bame and Trendefille, cannot stop themselves from treating me like family. They embrace me. They take my hand to lead me to the indoor seating area. They hug me constantly.

Just a week before the visit I lost my father after a long and terrible illness. There was something profound about feeling so loved in a familiar domestic setting. I was different now. How I received their outpourings of love felt more meaningful than ever. When they asked about my father they were heartbroken to hear of his death. Both my parents were invited innumerable times by the couple, but there was never a chance my mother would make the trip up the wild rocky roads!

During the visit they shared stories of time together with my travel companions. My ego was certainly entertained by their generosity of spirit in these retellings. Amongst their chats, the man of the house said something so lovely and unexpected that I was left speechless. He said that I am Kurveleshi – that is, I am of the Kurvelesh, I am one of them. Coming from one of the most respected members of the community, it meant the world to me.

To be of the Kurvelesh means a lot of things and will be different depending on who you ask. What seemed to be important to Bame was that I showed respect. Concepts like Besa and Kanun are important in the region. The former is all about keeping promises and acting honourably, like a pledge to do right by people. The latter is an overarching customary law governing all aspects of traditional life, passed on through oral tradition for centuries. The Kurvelesh is the last remaining area where Kanun survives beyond the Ottoman era and into the modern age.

Bame compared my team of archaeological researchers to other foreign groups from a range of disciplines. He said we were different, we embraced the mountains and the local culture. We took a different mindset into our research practice that included the community in both personal and professional terms. It is not an exaggeration to say that the team feels like Kurvelesh is a second home. It is no longer a remote foreign place full of the unknown. For us, it is now a place of familiar and familial faces and friendships.

We love the people of the mountains and they love us back.

One of the most unexpected comments I received was why my team laughs so much! We are a jovial bunch, always singing and joking around. It seems less easy to laugh in the Kurvelesh. Life has been hard in the wake of Communism, which is still a sensitive subject for most of the older community. People do not like to talk about their experiences in forced labour groups and the suppression of cultural traditions. We do not push the subject. Like much of Albania, this is also a site of several war fronts, not least of which saw the razing of the whole village by the Greeks in 1913. Remnants of these warfronts constitute a large body of our collection of artefacts from fieldwalking surveys. These objects tell stories themselves. The bullet casings from one misfiring gun are found in several locations adjacent to the modern village. Decorative uniform badges are found in local fields. Artillery shells and rusted guns are even collected and hung on display in homes and the single village café. The past is visible, even if it is unspoken.

We also received comments about how the team is managed. Curious locals asked me how I get my team to work without shouting at them. They were surprised that we were all volunteering our time unpaid and at our expense to investigate local heritage. The fact that we were not renumerated seemed to change their perspective on our intentions in a positive manner.

The community were outwardly pleased that we were fully open about our research. They talked about their assumptions about foreign groups and how the archaeology of the country has been pillaged by others. Our efforts included welcoming anyone to visit the site at their leisure. We were frequently visited by the young and old alike, sometimes as a detour from a walk or while passing with a herd of goats to laugh at us working in the rain. We made our work even more visible by taking finds for cataloguing to tables in the local café, so that the whole community could see everything we had and how we worked with it. Informal lessons and visualisations helped the community to understand the breadth of our work. They were delighted to learn of our multi-period approach and began to bring objects for us to record.

Over time, the community began to trust us. Through friendships and openness, they could see we were there for the right reasons. One local man showed up one day with a purple plastic bag filled with pottery sherds and bronze coins. He allowed us to photograph and record them onto our database. Every item was handed back to him the next day in perfect condition. This happened a few times. Each instance proved we meant what we said – we were not there to take anything, we were there to observe, learn and record only. At the end of each season, we handed all the finds to the local leadership for storage, with some pottery samples collected by the national Institute of Archaeology for their archives.

The community were also surprised that we value their knowledge and insights. We were positively enthused when offered tours of sites that might interest our archaeological endeavors. Every suggestion and prompt from the community was cherished and integrated into our research, valued as of equal value to anything considered more “academic”. This respect for local knowledge also helped our reputation.

The reports compiled after each season were hugely beneficial in communicating the value of the compiled data. They included drawings and maps that showed the community how the data comes together to tell their stories. They were also keen to see how we used LiDAR and drone imaging with our GPS records to map concentrations of finds across the landscape. The visual stories transcended linguistic barriers and helped everyone see why our work was useful and relevant to them. For example, local B&B owners typically spend the most time with visitors and our data is helpful in conveying the history of the landscape to those eager to learn, whether domestic or foreign. The community hopes that the information plaques that we have contributed to and walking trails supported by other international groups, created in recent years, will help foster better understanding of their local history. In the future, they will create a museum featuring artefacts collected by us and the community alike.

What makes our research fieldwork a bit different than most is that we take with us interdisciplinary perspectives. The Sustainable Development Goals (SDGs) are the lens by which we evaluate our work and contributions. This maps well onto local and national initiatives that seek to offset long-standing issues facing mountain communities. These issues include depopulation, losing traditional intangible cultural heritage, lack of attractive jobs, and environmental sustainability. Our heritage story is a small part of a much bigger picture. Rather than consider our work on our terms, we embrace domestic value systems and methods of seeing value.

One of our team has undertaken a project interviewing the community about their lives and experiences culminating in an MLitt dissertation, How do rural communities negotiate the legacy of a contested landscape in contemporary southern Albania? (A. Donnelly 2020, 95pps). Her work explores the landscape, agricultural practices, ethnobotanical knowledge, local recipes, conflict and rebellion, unique worship practices, folklore, and music. A taught masters student also produced a dissertation, How can social media function as a tool for initial tourist development? Lessons from rural Albania (R. Sanders 2020, 77pps). Her research reviewed the multivocality of tourists, the power of word-of-mouth marketing, and authenticity of touristic experience as demarcated by local business owners. Other outputs include fieldwork reports in 2018 (Tierney et al. 131pps) and 2019 (Tierney et al. 41pps), and multimedia engagement through public-engagement videos and at conferences. Additionally, I have integrated learnings from fieldwork into both undergraduate and postgraduate teaching at two universities. Several peer reviewed papers are underway and will be published soon. They include a comprehensive overview of the SDGs at Nivica, fieldwork survey analysis and artefact analysis.

In academia, quantifiable outputs and impacts are championed. Even in the realm of public engagement academic discourse, the value of authentic, deep and personal trusting relationships are muted. For me, hearts and minds in a framework of respect are worth more than anything else. If our research work enables us to contribute positively to a community that we adore, then our work is a success. I am optimistic that this personal narrative helps to contribute something to how we view ourselves as fieldwork researchers in relation to the places and communities that we encounter and, hopefully, embrace. In a world replete with mental health strain and professional angst, as the higher education system pinches more and more, there are things more valuable than traditional academic milestones. It is one thing to love one’s work, it is another to be truly loved back by the people we work for.

Intense downpours in the UK will increase due to climate change – new study

Posted on March 8, 2023March 8, 2023 by amanda.woodman-hardy

In July 2021, Kew in London experienced a month’s rain in just three hours. Across the city, tube lines were suspended and stations closed as London experienced its wettest day in decades and flash floods broke out. Just under two weeks later, it happened again: intense downpours led to widespread disruption, including the flooding of two London hospitals.

Colleagues and I have created a new set of 100-year climate projections to more accurately assess the likelihood of heavy rain downpours like these over the coming years and decades. The short answer is climate change means these extreme downpours will happen more often in the UK – and be even more intense.

To generate these projections, we used the Met Office operational weather forecast model, but run on long climate timescales. This provided very detailed climate projections – for every 2.2km grid box over the UK, for every hour, for 100 years from 1981 to 2080. These are much more detailed than traditional climate projections and needed to be run as a series of 20-year simulations that were then stitched together. Even on the Met Office supercomputer, these still took about six months to run.

We ran 12 such 100-year projections. We are not interested in the weather on a given day but rather how the occurrence of local weather extremes varies year by year. By starting the model runs in the past, it is also possible to verify the output against observations to assess the model’s performance.

At this level of detail – the “k-scale” – it is possible to more accurately assess how the most extreme downpours will change. This is because k-scale simulations better represent the small-scale atmospheric processes, such as convection, that can lead to destructive flash flooding.

More emissions, more rain

Our results are now published in Nature Communications. We found that under a high emissions scenario downpours in the UK exceeding 20mm per hour could be four times as frequent by the year 2080 compared with the 1980s. This level of rainfall can potentially produce serious damage through flash flooding, with thresholds like 20mm/hr used by planners to estimate the risk of flooding when water overwhelms the usual drainage channels. Previous less detailed climate models project a much lower increase of around two and a half times over the same period.

We note that these changes are assuming that greenhouse gas emissions continue to rise at current rates. This is therefore a plausible but upper estimate. If global carbon emissions follow a lower emissions scenario, extreme rain will still increase in the UK – though at a slower rate. However, the changes are not inevitable, and if we emit less carbon in the coming decades, extreme downpours will be less frequent.

The increases are significantly greater in certain regions. For example, extreme rainfall in north-west Scotland could be almost ten times more common, while it’s closer to three times more frequent in the south of the UK. The greater future increases in the number of extreme rainfall events in the higher resolution model compared with more traditional lower resolution climate models shows the importance of having k-scale projections to enable society to adapt to climate change.

As the atmosphere warms, it can hold more moisture, at a rate of 7% more moisture for every degree of warming. On a simple level, this explains why in many regions of the world projections show an increase in precipitation as a consequence of human-induced climate change. This new study has shown that, in the UK, the intensity of downpours could increase by about 5% in the south and up to about 15% in the north for every degree of regional warming.

However, it is far from a simple picture of more extreme events, decade by decade, as a steadily increasing trend. Instead, we expect periods of rapid change – with records being broken, some by a considerable margin – and periods when there is a pause, with no new records set.

This is simply a reflection of the complex interplay between natural variability and the underlying climate change signal. An analogy for this is waves coming up a beach on an incoming tide. The tide is the long-term rising trend, but there are periods when there are larger waves, followed by lulls.

Despite the underlying trend, the time between record-breaking events at the local scale can be surprisingly long – even several decades.

Our research marks the first time that such a high-resolution data set has spanned over a century. As well as being a valuable asset for planners and policymakers to prepare for the future, it can also be used by climate attribution scientists to examine current extreme rainfall events to see how much more likely they will have been because of human greenhouse gas emissions. The research highlights the importance of meeting carbon emissions targets and also planning for increasingly prevalent extreme rainfall events, which to varying degrees of intensity, look highly likely in all greenhouse gas emissions scenarios.

The tendency for extreme years to cluster poses challenges for communities trying to adapt to intense downpours and risks infrastructure being unprepared, since climate information based on several decades of past observations may not be representative of the following decades.

Seasonal Worker visa route encounters problems

Posted on February 27, 2023March 3, 2023 by amanda.woodman-hardy

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.

COP27: Egyptian student perspectives and insight

Posted on February 20, 2023March 3, 2023 by amanda.woodman-hardy

One of the privileges of being a student at the University of Bristol (UoB) is belonging to a diverse academic community comprised of students from many cultural, social and religious backgrounds. With the hosting of COP27 in Egypt this year, the Sustainability Network sought the opportunity to gain insight and perspectives first-hand from Egyptian UoB students around the significance and implications of the climate change focused conference being hosted in their country. Below is a recount of the respondents’ views and opinions.

Disclaimer: Views do not represent the University of Bristol nor the Sustainability Network. Names have been removed to protect the anonymity and privacy of the students who chose to speak.

The significance of climate change

Climate change is one of the most important issues the world is currently facing and will have wide ranging impacts that will influence our daily lives. Climate change, however, is often viewed as a future concern to be dealt with later – despite consequences and impacts thereof already being felt globally and locally making it a current and time sensitive issue. Climate change is also a complex, intersectional issue which coincides with issues of race, class, gender and inequality to name a few. The importance of speaking about climate change, even as non-experts, was highlighted by respondent A. Ultimately, as shared by respondent C, when thinking about climate change, we need to remember that the Earth is our only home (for now) and should be treated with care as we are borrowing it from future generations.

Climate change and Egypt

All respondents shared that either they themselves, or their families, have directly been affected by the impacts of climate change in Egypt. Respondent C shared that when speaking to parents and grandparents about the historical climate of Egypt, many changes to patterns and averages can be observed. This is in line with the scientific evidence that extreme weather events are getting more frequent, severe and widespread. Recurrent examples of climate change risks for Egypt mentioned by respondents and aligning to scientific consensus include:

Heat – Extreme temperatures driven by global warming impact the physical heat tolerance of individuals as well as affects infrastructure and agriculture negatively. Unlike other regional players who have the financial capacity for adaptation measures such as ubiquitous air conditioning, Egypt has less financial and infrastructural resilience to this concern.

Water scarcity – Water supply is a major a concern given climate change driven changing rainfall patterns in what is already an arid country. This issue was linked to regional geopolitical issues such as the contentious building of dams in nearby countries that alter regional water availability patterns.

Food security – The climate change risk to agriculture as a livelihood as well as for food availability was highlighted. The transboundary nature of climate change was reiterated as negative impacts to agriculture could affect food exports such as citrus and grains, thereby impacting global food supply chains. Should agriculture be detrimentally impacted, the cost of food associated with increasing food import dependency for Egypt would also impact local Egyptian food security as food would become less affordable.

Flooding – The threat of sea level rise as well as storm related flooding is of major concern, with many locations having limited financial and infrastructural adaptation capacity, thus posing a risk to infrastructure and human lives. The concerns of climate change refugees and regional migration motivated by climatic and economic variables were brought out in these discussions, once again demonstrating the global scope of climate change concerns.

Air pollution – Air quality, particularly in densely populated areas, is a major concern. Respondents attributed this to overpopulation, major car usage prevalence and general city congestion. Air pollution has health concerns as well as impacts natural weather patterns.

Despite first hand experiences and the extreme risks faced by many communities – particularly coastal communities such as Alexandria and densely populated regions such as Cairo – many respondents noted that climate change has not been a major focus for the Egyptian government over the past few years. This was perceived to be a result of conflicting urgent priorities such as unemployment, healthcare, poverty and education, as well as limited financial capacity and/or political will to address climate change simultaneously to these issues. It was pointed out that there are often financial incentives behind government investment decisions, with money often only being invested into projects that would see immediate returns. Others pointed out, however, that there has been significant progress made over recent years including reductions in plastic consumption, better waste management, investment into sustainable energy sources and biodiversity protection programs. Concerns around political stability and corruption hampering climate change action were noted – in line with the concerns of many LEDCs (Less Economically Developed Countries). The links between climate change and social disparities were demonstrated as the poorest and most vulnerable people would likely be impacted by climate change first.

The COP27 Conference

Respondents shared mixed feelings about the hosting of COP27 in Egypt. On one hand, this event does represent a significant geopolitical win and the bringing of Egypt and the MENA region to the global stage. This was a source of great pride to respondents, as representation of non-western countries in these typically Eurocentric global discussions was viewed to matter greatly. Moreover, the potential benefits to tourism and shaping of perceptions of Egypt as an innovative, up-and-coming and metropolitan country were seen to be positive. On the other hand, some respondents shared concerns about the efficacy of previous COP conferences and noted that the event tends to be overhyped and lead to very little meaningful impact – with goals of previous conferences such as a 1.5⁰C warning reduction targets not on track to being met. The risk of the conference becoming a blame-game or having little effect on the behaviour of large corporations that hold significant power were also mentioned. This COP conference is therefore viewed a make-or break opportunity in the climate change battle. Hopes for the setting of ambitious standards and legal precedents were shared. All respondents concluded by hoping this conference would be different and better than previous conferences, leading to tangible change and positive outcomes. (see the Sustainability Network Post-COP debrief for a reflection on the conference).

Looking forward

So where to from here? Whilst climate change is a global issue that will affect different places in different ways, respondents noted that everyone has a role to play in reaching towards a common goal. Respondent A reflected on the importance of critical thinking and communication, reminding us that disagreement is a common phenomenon that can be leveraged to understand the opinions and perspectives of others. All respondents reflected on the importance of education and awareness surrounding climate change. There were concerns surrounding the influence that COVID-19, the Russia-Ukraine conflict and other socioeconomic or geopolitical current affairs may have on the success of climate change action.

Generally, respondents reiterated the importance of incremental change and encouraged action and implementation over policies and legislation. The importance of international collaboration was revealed, as movements are stronger when we all work together and leverage the unique strengths of individuals and countries alike. Respondent C encouraged us to hold governments accountable, because as they pointed out, if we don’t, who will? The success of the COP27 conference will likely only be seen retroactively over longer time scales, so whilst one respondent urged dramatic outcomes and action to come from the discussions, another respondent viewed success as even one person acting better.

The Sustainability Network thanks the respondents for their time, honesty and patriotism. The kindness, care and passion of the Egyptian people was well demonstrated and we definitely want to visit the incredible beauty and culture of Egypt you shared with us.
