Seasonal Worker visa route encounters problems

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.

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

Posted on by janet.crompton

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.

Bristol is Global Competition 2019 – a student response to the global food crisis

Posted on by janet.crompton
Bristol Is Global finalists

Food – not one of us would be able to live without it and crucially, this obvious fact is understated. In the global north, with fast food delivery services available at our fingertips and supermarkets stocked with shelves of tinned cans, frozen meals and fresh fruit and veg, it is unsurprisingly easy to take food for granted. In an increasingly globalised world, where much of our food travels miles across oceans and roads, it is ever more common to find ourselves alienated from the cycles and processes that start in the soil and end up at the tip of our knives and forks. Our disconnection to food is significant given that the global food industry is in a hidden environmental crisis: a crisis of social, cultural, historical, economic, political, and geographical significance. As students, we recognise that if climate demands are not met within our lifetimes: water scarcity, diseases, droughts, floods, and the acidification of oceans will impact the security of our food in irrepressible ways (Empson 2016: 77-8).

And so, this year, Bristol is Global (BiG) asked students to address the question:

How can the university, students and the wider public address the problems with the local and global food industry?

Focusing on three sub-categories:

  1. Food waste
  2. The hunger-obesity paradox
  3. Single-use plastic packaging.

BiG is an annual, university-wide competition organised by students that is themed around a different global socio-political challenge each year, with the winning team being awarded £500. The competition provides an opportunity for students from different disciplines to collaboratively develop a solution to a global problem on a local scale, founded on the belief that no global challenge will ever be resolved by one person, but rather a collective effort of countless individuals each making small actions.

To introduce the theme, Joy Carey, an expert in sustainable food planning who is currently a member of the Bristol Food Policy Council along with Natalie Fee, an environmental campaigner against plastic pollution, gave inspiring talks to launch the competition. This was followed by a panel debate to help students better understand the complex issue at hand a panel event took place. Representatives from Bristol Waste Company, Fair Trade Network, Community Farm, as well as our own Professor Jeffrey Brunstrom engaged in a thought provoking discussion with the students.

This year, the four finalist teams came up with four creative and diverse ideas that could potentially have a significant impact on the Bristol community:

  1. RecycleWise: A comprehensive information pack distributed to second year flats educating students on good recycling practices.
  2. Bright: An all-inclusive app with tutorial videos, interactive maps and reward schemes to encourage people to follow more sustainable eating habits.
  3. Eat Well Bristol: Student-volunteer run holiday cooking sessions in primary schools to make organic and healthy eating more accessible to underprivileged families in Bristol.
  4. Green Brewery Initiative: Growing indoor crops and herbs using plastic bottles rather than pots and used coffee grounds instead of fertiliser to engage the University community in reducing waste.

Members from LettUs Grow, a successful University of Bristol start-up developing vertical farming technology met with the teams to help them refine their pitch. In the final event, each team presented their ideas to a panel of judges. The quality of research and originality in each proposal was truly impressive, as well as the passion and enthusiasm shown by all four teams. The judges ultimately decided to chip in an extra £100 and fund two teams, the Bright App and RecycleWise, as well as providing continued support to all four teams to carry on with their projects. With Bristol Going for Gold (Bristol’s ambition to become the first Gold Award Sustainable Food City in the UK by 2020), each proposal has tremendous potential to help the city reach its goal.

As organisers of BiG we would like to thank the Cabot Institute for providing invaluable support throughout the competition. We would also like to extend our thank you to the Alumni Grant Foundation for funding to further help the teams implement their ideas.

Next year BiG will return with a different socio-economic issue, challenging students to come up with solutions that can truly help the Bristol community in different ways. We hope to engage more students and encourage the entire university community to engage in the issues we face.

What global threats should we be most worried about in 2019?

Posted on by janet.crompton

The Cambridge Global Risk Index for 2019 was presented on 4 December 2018 in the imposing building of Willis Towers Watson in London. The launch event aimed to provide an overview of new and rising risk challenges to allow governments and companies to understand the economic implications of various risks. My interest, as a Knowledge Exchange Fellow working with the (re)insurance sector to better capture the uncertainties embedded in its models, was to find out how the index could help insurance companies to better quantify risks.

The presentation started with the Cambridge Centre for Risk Studies giving an introduction on which major world threats are included in the index, followed by a panel discussion on corporate innovation and ideation.

The Cambridge Global Risk Index quantifies the impact future catastrophic events (be they natural or man-made) would have on the world’s economy, by looking at the GDP at risk in the most prominent cities in the world (GDP@Risk). The Index includes 22 threats in five categories: natural disasters and climate; financial, economics and trade; geopolitics and security; human pandemic and plant epidemic; and technology and space.

Global Risk Index 2019 Threat Rankings (Cambridge Global Risk Index 2019 Executive Summary)

The GDP@Risk for 2019 for the 279 cities studied, which represents 41% of the global GDP, has been estimated to be $577bn or 1.57% of the GDP of 2019. The GDP@Risk has increased since last year by more than 5%, which was caused by both an increase in GDP globally and a rise in the chances of losses from a cyber attack and other threats to richer economies. Risk is becoming ever more interconnected due to cascading threats, such as natural hazards and climate events triggering power outages, geopolitical tensions triggering cyber attacks sponsored by states, conflicts worsening human epidemics, and trade wars triggering sovereign crises, which in turn caused social unrest.

Nonetheless, the GDP@Risk can be reduced  by making cities more resilient, that is improving the ability of a city to be prepared for a shock and to recover from it.  For example, if the worst off 100 cities in the world would be as prepared as the top cities, they could reduce their exposure to risk by around 30%, which shows the importance of investing in resilience and recoverability. This is a measure of what the insurance industry calls the “protection gap”, how much could be earned from investments to improve the preparedness and resilience of a city to shocks. How fast a city recovers depends on the ability to access capital, to reconstruct and repair factories, houses and infrastructure, to restore consumers’ confidence and to reduce the length of business interruption.

Global Risk Index 2019 Growth by Sub-Category ($, bn) (Cambridge Global Risk Index 2019 Executive Summary)

Natural catastrophe and climate

After a 2017 with the second highest losses due to natural disasters, 2018 saw several record-breaking natural catastrophes as well. This year we have experienced events from magnitude 7.5 earthquakes and tsunami in Indonesia, which caused more then 3000 deaths, to the second highest number of tropical cyclones active in a month, from Typhoon Mangkhut in the Philippines, to Japan’s strongest storm in the last two decades. Hurricanes have beaten records too, with hurricane Florence in North Carolina becoming the 2nd wettest hurricane on record, which caused $10 bn losses, and hurricane Michael in Florida reaching the greatest wind speeds ever recorded, which caused $15 bn losses.

Floods in 2018 caused heavy death tolls in Japan and south India, with 225 and 500 fatalities respectively, the former showing the weakness of an ageing city infrastructure, while the latter raising criticism on poor forecasting and management of water resources. Droughts raged in South Africa, Australia, Argentina, Uruguay and Italy reducing harvests, while wildfires in California were the largest on record, which caused $20 bn losses. Extreme events have made it to weather events too, with extreme heatwaves, as the hottest summer in the UK, comparable to the one of 1976, and the heatwave in Japan which hospitalised 35,000 people, as well as with extreme freeze, as the “Beast from the East” in the UK which caused losses estimated at $1 billion per day.

Extreme events are becoming ever more frequent due to climate change, with the next few years expected to be anomalously warm, even on top of the regular climate change. This hints that the rising trend in losses due to natural catastrophe and climate is not due to stop.

Devastation from the cyclone in Tonga, 2018.

Finance, economics and trade

Market crash is the number one threat for 2019, which could cause more than $100 billion in losses. Nonetheless global financial stability is improving due to increased regulation, but risk appetite has increased as well due to positive growth prospects and low interest rates, which increases financial vulnerabilities. Trade disputes between the US and China and the US and Europe are disrupting the global supply chains. The proportion of GDP@Risk has increased in Italy due to policy uncertainty and increased sovereign risks, while in countries such as Greece, Cyprus and Portugal sovereign debt risks have decreased following restructuring of their debt and country level credit rating upgrades.

Geopolitics and security

The risk from geopolitics and security worldwide has remained relatively similar compared to last year, with roughly the same countries being in conflict as in 2017. Iran’s proxy presence remains in conflicts in Yemen, Iraq, Israel, Syria and Lebanon, while social unrest has increased risk in Yemen, Nicaragua, Venezuela, Argentina, Iraq and South Africa. The conflict in Yemen has caused the world’s worst humanitarian crises in 2018, with more than 2 million displaced, with food shortages and malnutrition causing cholera outbreak. The total expected loss from this category is similar to the one from financial, economic and trade risk.

Technology and space

Technology and space is the category with the lowest expected GDP at risk. Nevertheless, the risk has increased over recent years, with cyber attacks becoming ever more frequent due to the internationalisation of cyber threat, the increasing size and cost of data breaches, the continued disruption from DDoS attacks, the threat to critical infrastructure, and its continuous evolution and sophistication. Cyber attacks have climbed one level in the ranking this year, assuring the 6th overall position. In 2017 the WannaCry ransomware attacks affected 300,000 computers across 150 countries disrupting critical city infrastructure, such as healthcare, railways, banks, telecoms and energy companies, while NotPetya produced quarterly losses of $300 million for various companies. The standstill faced by the city of Atlanta when all its computers were locked due to a ransomware attack in March caused £2.6 million to be spent, and another $9.5 million are expected. This attack highlighted the breath of potential disruption, with energy, nuclear, water, aviation and manufacturing infrastructure at risk. Moreover 66% of companies are estimated to have experienced a supply chain attack, costing on average $1.1 million per attack. In response to these threats, countries are increasing their spending on cyber offensive capability, with the UK spending hundreds of millions of pounds. Power outage, nuclear accident and solar storm are not at the top of the threats ranking globally, but solar storms could cause over $4bn of GDP@Risk in North American cities, due to their position in northern latitudes, leaving 20-40 million people without power.

 

Health and humanity

The greatest threat to humanity according to the UN is anti-microbial resistance, with areas in the world already developing strains of malaria and tuberculosis resistant to all available medicines. It is expected that over the next 35 years 300 million people will die prematurely due to drug resistance, decreasing the world’s GDP between 2 and 3.5% in 2050. Major epidemics have remained largely constrained in the same areas as last year, and are fuelled by climate and geopolitical crises which aggravates hygiene and public health, such as the Yemen and Somalia cholera outbreaks. Plant epidemics have not increased, with the ongoing problems of Panama disease in bananas, coffee and wheat rust, and the xylella fastidiosa still affecting olive plants in southern Europe.

Corporate innovation and ideation discussion

The panel discussed the importance of the Cambridge Global Risk Index to prepare companies for future threats. For example, for insurance companies including the index in their management of risk would allow them to be better prepared and more profitable. I found the words of Francine Stevens, director of Innovation at Hiscox, particularly inspiring. She talked about how the sheer volume of research produced is often too large to be digested by practitioners, and how workshops might help to bring people with similar interests together to pull out what are the most exciting topics and challenges to work on. As a Knowledge Exchange Fellow myself, this strikes a familiar chord, as it is my job to transfer research to the insurance sector and I have first-hand experience on the importance of adopting a common language and identifying how industry uptakes new research and methods.

Francine has also talked about the importance of collaboration between companies, a particularly sensitive topic in the highly competitive insurance sector. This topic emerged also at the insurance conference held by the Oasis Loss Modelling Framework in September, where the discussion touched on how non-competitive collaborations could bring the sector forward by avoiding duplication. Francine’s final drop of wisdom was about the importance of diversity to drive innovation, and how having a group of smart people with diverse backgrounds often delivers better results than a group of high-achievers with the same background. And this again sounded very familiar!

Travelling through Asia’s breadbasket

Posted on by janet.crompton

This is the second of a series of blogs from a group of University of Bristol Cabot Institute researchers who are on a remote expedition (funded by BCAI) to find out more about Kazakh agriculture and how farmers are responding to their changing landscape.

Queen’s ‘Bohemian Rhapsody’ played on the car radio as we drove through endless fields of stubble stretching into the horizon in every direction. We were 2 days into our 3-day, 2,345km journey from Astana to our field site, and it was easy to see why Kazakhstan is referred to as Asia’s breadbasket. Spring had finally arrived after an unusually long winter.  Tractors were busy burning, ploughing and planting, disappearing into the distance with each pass of the field.

The vast, flat steppe has provided the opportunity for cereal production on a scale unrivalled by the UK’s comparatively small field enclosures. In 2017, Kazakhstan held wheat stocks of 12MMT (million metric tonnes), making UK’s 1.4MMT seem like a drop in the ocean by comparison. Kazakhstan exports wheat globally and is a key player in global food security. Grain elevators capable of storing more than 100,000 tonnes of grain dominate the skyline of every major town and soon became a familiar feature of the landscape to us.

Our journey was punctuated every 6 hours or so by stops at restaurants that seemed to appear out of nowhere. Each one was as unique as the last, their bright colours a reflection of the cheerful nature of the Kazakh people. The popular Tabletkas parked outside reminded me of VW Transporters, and the friendly locals reminded me of my Welsh roots, where strangers greet you on the street.

The restaurants served a range of traditional Kazakh comfort food – meat and milk based meals like borscht, always served with bread, of course. Bread, or нан (pronounced naan) is a staple food here and is said to be the most important part of the dinner table. The menu, written in the Cyrillic alphabet, was indecipherable to me at first and I had to pester the Kazakh and Russian members of our team to help me choose a meal each time. Based on my excited reaction when I finally discovered the image recognition feature of my Google Translate app, you would have thought that I had never seen modern technology before. In truth, I was just relieved to not be such a burden on the rest of team!

Before long we were back on the road and as the hours passed I looked forward to getting to camp and getting started with our work. We planned to visit remote villages, thousands of kilometres off the tourist track, to survey farmers about how they cope with weather extremes such as this year’s particularly harsh winter. But for now, we had run out of time and energy. The sun was setting and we needed to find a place to rest for the night. We headed for the dim twinkling lights of Aktobe, passing a tractor working into the night, illuminating a cloud of dust in its wake. When we eventually found a motel with rooms available, I found it difficult to sleep. I couldn’t wait for the final leg of our journey to our wild camp in the Kazakh steppe.

Setting off on a BCAI expedition to Kazakhstan

Posted on by janet.crompton

This is the first of a series of blogs from a group of University of Bristol Cabot Institute researchers who are on a remote expedition (funded by BCAI) to find out more about Kazakh agriculture and how farmers are responding to their changing landscape.

Ghost towns on the Kazakh steppe look as though they are centuries old, but it is an illusion. They have been sandblasted relentlessly by the force of the steppe since they were abandoned, less than 40 years ago, after the breakdown of the Soviet Union. This is one area on earth that people have largely failed to tame, but as the human population increases the country’s agricultural systems are rapidly developing and focus is turning to the steppe once again. At the same time, farmers must adapt to recent changes in climate – drier summers limit crop production and water availability, and changing patterns of snowfall and snowmelt threaten the lives of livestock. I am about to embark on a remote expedition to find out more about Kazakh agriculture and how farmers are responding to their changing landscape. Follow this blog series for updates from the field.

Since 2000, approximately 5,000,000 additional hectares of land have been sown for cropping, and approximately 2,000,000 each additional sheep, cattle and horses are kept in Kazakhstan. This increase in livestock productivity is largely driven by smallholder farmers, who rely on livestock for up to a fifth of their family’s food. However, climate change has been felt disproportionately in Central Asia, threatening food security. National Geographic recently reported that over half a million animals failed to survive the winter in neighbouring Mongolia due to a combination of lethal winter conditions and poor summer crop growth, so I’m anxious to see how the Kazakhs fared.

I’m told that in the Ural region in Western Kazakhstan, wheat production, livestock and wildlife exist in close contact, and that this is the best place to start my research. I’m set to fly to Astana tomorrow to join colleagues from the Association for the Conservation of Biodiversity of Kazakhstan (ACBK) on the three-day, 2,000km journey to the far west. With the help of ACBK and Bristol PhD student Munib Khanyari, I will interview farmers spread out over an area the size of England, skirting along the Russian border and the Caspian Sea. I’ll spend my evenings wild camping off-grid under the stars for 2-3 weeks. There will be no fresh water, no toilets and no internet – the team and I have to carry everything we need in order to survive the duration. Wish me luck!

The new carbon economy – transforming waste into a resource

Posted on by janet.crompton

As part of Green Great Britain Week, supported by BEIS, we are posting a series of blogs throughout the week highlighting what work is going on at the University of Bristol’s Cabot Institute for the Environment to help provide up to date climate science, technology and solutions for government and industry.  We will also be highlighting some of the big sustainability actions happening across the University and local community in order to do our part to mitigate the negative effects of global warming. Today our blog will look at ‘Technologies of the future: clean growth and innovation’.

On Monday 8 October 2018, the IPCC released a special report which calls upon world governments to enact policies which will limit global warming to 1.5°C compared with pre-industrial levels, failure to do so will drastically increase the probability of ecosystem collapses, extreme weather events and complete melting of Arctic sea ice. Success will require “rapid and far-reaching” actions in the way we live, move, produce and consume.

So, what comes to mind when you hear carbon dioxide – a greenhouse gas? A waste product? You’re not wrong to think that given the predicament that our planet faces, but this article is going to tell the other side of the story which you already know but is often forgotten.

For over a billion years, carbon dioxide has been trapped and transformed, almost miraculously, into an innumerable, rich and complex family of organic molecules and materials by photosynthetic organisms. Without this process, life as we know simply would not have evolved. Look around you, – I dare say that the story of carbon dioxide is weaved, one way or another into all the objects you see around you in this moment. Whether it’s the carbon atoms within the material itself – or that old fossilised sourced of carbon was used to smelt, melt or fabricate it.

The great growth and development of the last two centuries has been defined by humanity’s use of fossilised carbon which drove the first and second industrial revolutions. But now – the limitations of those very revolutions are staring us in the face and a new revolution is already underway, albeit it quietly.

An industrial revolution is said to occur when there is a step change in three forms of technology, Information, Transport and Energy. The step change that I will discuss here is the use of carbon dioxide coupled with renewable energy systems to deliver a circular carbon economy that aims to be sustainable, carbon neutral at worst and carbon negative at best. This burgeoning field comes under the name carbon capture and utilisation (CCU). CCU, represents a broad range of chemical processes that will most directly impact energy storage and generation and the production of chemical commodities including plastics and building aggregates such as limestone.

In our research we are developing catalysts made of metal nanoparticles to activate and react CO2 to form chemicals such as carbon monoxide (CO), formic acid, methanol and acetate. They be simple molecules – but they have significant industrial relevance, are made on vast scales, are energy intensive to produce, and all originate in some way from coal. The methods that we are investigating while being more technically challenging, consume just three inputs – CO2, water and an electrical current. We use a device called an electrolyser, it uses electricity to break chemical bonds and form new ones. The catalyst sits on the electrodes. At the anode, water is broken into positively charged hydrogen ions called protons and oxygen, while at the opposite electrode, the cathode, CO2 reacts with the protons, H+, to form new molecules. It sounds simple but encouraging CO2 to react is not easy, compared to most molecules, CO2 is a stubborn reactant. It needs the right environment and some energy such as heat, electricity or light to activate it to form products of higher energy content. The chemicals that can be produced by this process are industrially significant, they are used in chemical synthesis, as solvents, reactants and many other things. CO for example can be built up to form cleaner burning petroleum/diesel-like fuels, oils, lubricants and other products derived by the petrochemical industry.

Formic acid and methanol may be used to generate energy, they can be oxidised back to CO2 and H2O using a device called a fuel cell to deliver electricity efficiently without combustion. One day we could see electrically driven cars not powered by batteries or compressed hydrogen but by methanol which has a higher volumetric energy density than both batteries and hydrogen. Batteries are heavy, too short-lived and use high quantities of low abundance metals such as lithium and cobalt – meaning their supply chains could suffer critical issues in the future. While the compression of hydrogen is an energy intensive process which poses greater safety challenges.

However, there are still many hurdles to overcome. I recently went to the Joint European Summer School on Fuel Cell, Electrolyser and Battery Technologies. There I learned about the technical and economic challenges from an academic and industrial perspective. In an introductory lecture, Jens Oluf Jensen was asked “When will we run out of fossil fuels?”, his answer “Not soon enough!”. An obvious answer but there is something I wish to unpick. The task for scientists is not just to make technologies like CO2 capture, CO2 conversion and fuel cells practical – which I would argue is already the case for some renewable technological processes. The greatest challenge is to make them cost competitive with their oil-based equivalents. A gamechanger in this field will be the day that politicians enact policies which incorporate the cost to the environment in the price of energy and materials derived from fossil fuels, and even go so far as to subsidise the cost of energy and materials-based on their ability to avoid or trap carbon dioxide.

Even without such political input there is still hope as we’ve seen the cost of solar and wind drop dramatically, lower than some fossil fuel-based power sources and only with limited government support. Already there are companies springing up in the CCU sector. Companies like Climeworks and Carbon Engineering are demonstrating technology that can trap CO2 using a process known as Direct Air Capture (DAC). Carbon Engineering is going even further and developing a technology they call Air to Fuels™. They use CO2 from the air, hydrogen split from water and clean electricity to generate synthetic transportation fuels such as gasoline, diesel or jet fuel. You may question why we should need these fuels given the rise of battery powered vehicles but a better solution for fuelling heavy goods vehicles, cargo ships and long-haul flights is at the very least a decade way.

In 1975, Primo Levi wrote a story about a carbon dioxide molecule and he said in relation to photosynthesis “dear colleagues, when we learn to do likewise we will be sicut Deus [like God], and we will have also solved the problem of hunger in the world.”. The circular carbon economy may still be in its infancy, but the seeds have sprouted. Unlike the first and second industrial revolution, the 3rd industrial revolution will not be dependent on one single energy source but will be a highly interdependent network of technologies that support and complement each other in the aim of sustainability, just like nature itself.

Africa looking to strategic partnerships to rein in food and nutrition insecurity

Posted on by janet.crompton

World hunger continued to rise for the third consecutive year according to the UN’s Food and Agriculture Organization (FAO)’s latest report. The data identifies climate variability as one of the major contributing factors to this worrying statistic. The intricate relationship between climate change and food security culminates in a major challenge that has rattled individuals, organisations and governments alike for decades. In the coming decades, Africa—which faces the biggest food security challenge in present times—will need more strategic partnerships to unlock its food security potential.Nearly one in every nine people—a significant proportion of whom live in Sub-Saharan Africa—go to bed hungry every night. So significant is this challenge that the United nations lists ending hunger, achieving food and nutrition security and promoting sustainable agriculture by 2030 second of its 17 Sustainable Development Goals (SDGs).

It is a daunting challenge made worse by an exploding global population set to hit 9 billion by 2050. Nonetheless, governments and other stakeholders worldwide are drawing inspiration from the fact that, despite the increases of the past three years, hunger overall has reduced by almost half in the past two decades. This has been made possible through deliberate efforts to increase agricultural production with minimal environmental impact.

Contemporary Agricultural Science Technology and Innovations (STIs) are pivotal to increasing agricultural production, food security, and promoting economic growth in Africa. However, realizing these aspirations greatly depends on leveraging the synergistic capabilities of the diverse actors within the sector towards building stronger partnerships and increased accountability for greater impact.

The nature of Agricultural Research for Development (AR4D) paradigms around the world is rapidly evolving, with new technologies constantly emerging and making the agricultural sector more knowledge intensive and innovations driven. In addition, the role of the private sector in agricultural R&D is increasingly more prominent, with Public-Private Partnerships (PPPs) being touted as an ideal model for accelerating technology transfer, commercialization, and delivery of research outputs to end-users for optimal research impact. Innovative partnerships between the public and private sectors are especially important for attracting investments and financing innovative solutions for agriculture in developing nations.

To drive this innovative and responsive research agenda, scientists globally are increasingly coming together in collaborative partnerships to share resources towards ensuring that the world will be able to feed nine billion people by 2050.

Among these is the Community Network for African Vector-Borne Plant Viruses (CONNECTED)—a Vector-borne Disease Network awarded to the University of Bristol—which held its Africa Launch Conference  in May 2018. The network—which is closely involved with the Cabot Institute—aims inter alia to build a sustainable network of multi-disciplinary international scientists, to deliver solutions to devastating crop diseases.
 

Participants at the CONNECTED Network Africa Launch, May 2018

Three months on, and the Network is already making good on its promise. Following the first CONNECTED pump prime funding call soon after the Network’s Africa launch, research funding grants have been awarded to Network members working in African and European research institutions in classic triangular collaborations to achieve the ideals of the Network.

In August 2018, global science leaders congregated in Durban, South Africa for the inaugural Bio Africa convention. The conference provided opportunities to build capacity and drum up support for increased investment in, and support for Africa’s growing biotech industry. It is hoped that networks built there will enrich the implementation of past and existing Africa-led initiatives for growth and sustainable development, especially in the bio-economy sector.

While food is an easy topic to get people involved with, rising concerns about some aspects of agricultural technology bring unique dynamics to this area. A July 25 ruling by the European Court of Justice imposed exacting regulatory restrictions on the use of gene editing in crop improvement. This adds to existing regulatory stalemates—mostly in Europe and Africa—blocking the use of products of modern agricultural technologies such as genetic engineering and gene editing to deliver important crop varieties to the world’s most vulnerable people.

In Uganda for instance, genetically modified biofortified and bacterial wilt resistant bananas, and blight resistant potatoes remain locked up in confined field trials due to the absence of an enabling regulatory environment for commercialisation. Research is on-going—using genetic engineering—on virus resistant cassava, insect resistant and drought tolerant maize, and nitrogen use efficient rice among other key food security crops.

The ebb and flow of global politics and science remains a determinant factor in whether or not agricultural STIs can contribute to ending hunger by 2030 per the SDGs. Cognizant of the constraints new breeding technologies are facing to deliver impact, initiatives like Uganda Biosciences Information Center (UBIC) have been established to support the stewardship process to ensure that key agricultural technologies reach the people that need them most.

This is achieved through creating and raising awareness of modern agricultural biosciences and biosafety, to facilitate balanced, fact-based and objective discourse on modern biosciences in Uganda and beyond. Elsewhere, the Open Forum on Agricultural Biotechnology (OFAB), International Service for Acquisition of Agri-biotech Applications (ISAAA) and Cornell Alliance for Science to mention but a few, are championing the same cause at regional and global levels.

In many ways gentle calls to action, such initiatives complement the millions of voices highlighting the global food challenge and imploring all humanity to spring to action to ensure that everyone has a seat at the (dining) table.

Policy coherence and coordination among different actors to end hunger remains key to delivering much needed solutions to global food and nutrition security. To end hunger, targeted steps must be taken to help people access the tools they need to create agricultural prosperity and progress. But we can’t just hope and pray, we have to take action—and Africa seems to be beginning to do just that!

Belo Monte: there is nothing green or sustainable about these mega-dams

Posted on by janet.crompton

There are few dams in the world that capture the imagination as much as Belo Monte, built on the “Big Bend” of the Xingu river in the Brazilian Amazon. Its construction has involved an army of 25,000 workers working round the clock since 2011 to excavate over 240m cubic metres of soil and rock, pour three million cubic metres of concrete, and divert 80% of the river’s flow through 24 turbines.

Costing R$30 billion (£5.8 billion), Belo Monte is important not only for the scale of its construction but also the scope of opposition to it. The project was first proposed in the 1970s, and ever since then, local indigenous communities, civil society and even global celebrities have engaged in numerous acts of direct and indirect action against it.

While previous incarnations had been cancelled, Belo Monte is now in the final stages of construction and already provides 11,233 megawatts of energy to 60m Brazilians across the country. When complete, it will be the largest hydroelectric power plant in the Amazon and the fourth largest in the world.

A ‘sustainable’ project?

The dam is to be operated by the Norte Energia consortium (formed of a number of state electrical utilities) and is heavily funded by the Brazilian state development bank, BNDES. The project’s supporters, including the governments of the Partido dos Trabalhadores (Workers’ Party) that held office between 2003 and 2011, have justified its construction on environmental grounds. They describe Belo Monte as a “sustainable” project, linking it to wider policies of climate change mitigation and a transition away from fossil fuels. The assertions of the sustainability of hydropower are not only seen in Brazil but can be found across the globe – with large dams presented as part of wider sustainable development agendas.

With hydropower representing 16.4% of total global installed energy capacity, hydroelectric dams are a significant part of efforts to reduce carbon emissions. More than 2,000 such projects are currently funded via the Clean Development Mechanism of the 1997 Kyoto Protocol – second only to wind power by number of individual projects.

While this provides mega-dams with an environmental seal of approval, it overlooks their numerous impacts. As a result, dams funded by the CDM are contested across the globe, with popular opposition movements highlighting the impacts of these projects and challenging their asserted sustainability.

Beautiful hill, to beautiful monster

Those standing against Belo Monte have highlighted its social and environmental impacts. An influx of 100,000 construction and service workers has transformed the nearby city of Altamira, for instance.

Hundreds of workers – unable to find employment – took to sleeping on the streets. Drug traffickers also moved in and crime and violence soared in the city. The murder rate in Altamira increased by 147% during the years of Belo Monte construction, with it becoming the deadliest city on earth in 2015.

In 2013, police raided a building near the construction site to find 15 women, held against their will and forced into sex work. Researchers later found that the peak hours of visits to their building – and others – coincided with the payday of those working on Belo Monte. In light of this social trauma, opposition actors gave the project a new moniker: Belo Monstro, meaning “Beautiful Monster”.

The construction of Belo Monte is further linked to increasing patterns of deforestation in the region. In 2011, deforestation in Brazil was highest in the area around Belo Monte, with the dam not only deforesting the immediate area but stimulating further encroachment.

In building roads to carry both people and equipment, the project has opened up the wider area of rainforest to encroachment and illegal deforestation. Greenpeace has linked illegal deforestation in indigenous reserves – more than 200km away – to the construction of the project, with the wood later sold to those building the dam.

Brazil’s past success in reversing deforestation rates became a key part of the country’s environmental movement. Yet recently deforestation has increased once again, leading to widespread international criticism. With increasing awareness of the problem, the links between hydropower and the loss of the Amazon rainforest challenge the continued viability of Belo Monte and similar projects.

Big dams, big problems

While the Clean Development Mechanism focuses on the reduction of carbon emissions, it overlooks other greenhouse gases emitted by hydropower. Large dams effectively emit significant quantities of methane for instance, released by the decomposition of plants and trees below the reservoir’s surface. While methane does not stay in the atmosphere for as long as carbon dioxide (only persisting for up to 12 years), its warming potential is far higher.

Belo Monte has been linked to these methane emissions by numerous opposition actors. Further research has found that the vegetation rotting in the reservoirs of dams across the globe may emit a million tonnes of greenhouse gases per year. As a result, it is claimed that these projects are – in fact – making a net contribution to climate change.

Far from providing a sustainable, renewable energy solution in a climate-changed world, Belo Monte is instead cast as exacerbating the problem that it is meant to solve.

The ConversationBelo Monte is just one of many dams across the globe that have been justified – and funded – as sustainable pursuits. Yet, this conflates the ends with the means. Hydroelectricity may appear relatively “clean” but the process in which a mega-dam is built is far from it. The environmental credentials of these projects remain contested, with Belo Monte providing just one example of how the sustainability label may finally be slipping.

Pollination and International Development: How bees can help us fight poverty and feed the world

Posted on by janet.crompton

Animal pollinators are the industrious workers in the factory of life – transporting pollen from one flower to another to ensure successful fertilisation. 75% of our crop plants benefit from this free service which can increase the yield, quality and even shelf-life of their products. This translates to a US$235-577bn value to global agriculture each year. Many of our favourite foods – strawberries, coffee and cocoa – can end up shrivelled and tasteless without pollination. This ecosystem service is under increasing threat however, as pollinators face the potent cocktail of pressures we have laid upon them, declining in numbers across various parts of the world.

But what has all this got to do with international development? From what we can tell, communities in developing countries [1] are more reliant on pollinators than almost anyone, standing to lose important income, livelihoods, nutrition and cultural traditions if pollinators decline. And yet, although a number of researchers across the developing world have made substantial and important contributions to this field, limited resources and capacity have meant that only a small proportion of pollination research has focused on these regions. In fact, there isn’t even enough data to know what is happening to pollinators in the developing world, let alone how we can best conserve them and their values to human wellbeing.

Over two billion people in developing countries are reliant on smallholder farming and therefore indirectly reliant on pollinators, without necessarily knowing it.  Many valuable cash crops, for example coffee, cocoa and cashews, are highly pollinator dependent and almost exclusively grown in the developing world, providing income for millions of people. In fact the reliance on pollinator-dependent crops has increased faster in the developing world than anywhere else. Reliance on beekeeping for income and livelihoods has also increased and is becoming a common component of sustainable development projects worldwide.

Worryingly, declines in pollination will have deeper consequences than just the loss of crop yields and income. Because many of the most nutritionally important food groups such as fruits, nuts and vegetables are also the most pollinator-dependent, pollinator declines are likely to shift the balance of people’s diets away from these foods. As a result, many millions of people around the world, particularly in developing countries, are expected to become deficient in important micronutrients such as vitamin A, vitamin C, iron and folate, resulting in millions of years of healthy life lost.

So what is being done about all this? In recognition of the importance of pollinators to human welfare and the threats facing them, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) commissioned a global assessment of Pollinators, Pollination and Food Production, published in 2016. This triggered a great wave of political and media attention and has resulted in the incorporation of the report’s key findings into the Convention on Biological Diversity (CBD). Many governments are now in the process of developing national pollinator strategies, including the developing nations of Brazil, Argentina, Colombia, South Africa and India. On this wave of momentum, the CBD has also requested the UN Food and Agriculture Organisation (FAO) to update their International Pollinator Initiative (IPI) which aims to build greater understanding, management and conservation of pollinators around the world. This international attention won’t last forever though, so it is important that the current momentum is sustained and built upon as soon as possible, ensuring as many countries as possible – particularly in the developing world – are involved.

The UK has a valuable opportunity to contribute to these efforts. As a centre of excellence for pollination science, it is the second largest funder and producer of pollination research after the US. But only c.6% of the £95M we have contributed to pollination research in the last 10 years has any link or collaboration with a developing country (ÜberResearch 2018). As more of the UK’s Official Development Assistance budget is made available for research, there is a shift in emphasis towards research that directly contributes towards international development. New funding programmes are encouraging the UK research community to engage in collaborative projects with researchers in developing countries, building valuable research capacity. With the relevance of pollination and agro-ecology to addressing the UN’s Sustainable Development Goals, these topics may fit into this new funding landscape. However, to be effective and ethical, partners and institutions in developing countries must be involved in the design of, and stand to benefit from these collaborations. See here for a UKCDS report outlining the ways in which academics and funders can help ensure fair partnerships.

As populations in the developing world expand, along with per-capita food demands, these issues become all the more pressing. Food production will need to increase by 70% come 2050 and this cannot be achieved by simply expanding agricultural land or fertilizer input. To ensure people are well-fed, in a way that is sustainable and ethical, we will have to intensify our farming in new ways. Understanding and managing pollination may be an important part of this and is something that researchers, politicians, agriculturalists and development workers will need to engage with sooner rather than later.

[1] For simplicity, we use the term ‘developing countries’ to refer to all countries listed in the Organisation for Economic Co-operation and Development’s (OECD) Development Assistant Committee (DAC) list of Official Development Assistance (ODA) recipients. This includes countries from a range of economic classifications, from ‘Least Developed’ to ‘Upper Middle Income’ which includes the nations of China and Brazil. Whilst we group all these nations under the broad term of ‘developing country’, we acknowledge the great heterogeneity between them in terms of wealth, development and research capacity.
