How water stress impacts on migration

Posted on by janet.crompton

In this special blog series, Migration Mobilities Bristol (MMB) and the Cabot Institute for the Environment bring together researchers from across the University of Bristol to explore connections between movement and the environment from a multi-disciplinary perspective. Their diverse approaches highlight the importance of developing frames that incorporate both migration and environment, and in so doing benefit our understandings of both. 

————————————-

In 2015, Ioane Teitiota and his family were deported from New Zealand to the Pacific island nation of Kiribati. His asylum application had been based on the grounds that water, due to sea level rise, had made the island uninhabitable in various ways: there was a shortage of clean drinking water; the available habitable land had decreased, which had led to increased insecurity because of violent land disputes; and the main activity, subsistence farming, was impeded.

Water has always had a major influence on where we live. Whether drawing us to new locations or forcing us from existing ones, water has always been intricately connected to the movement of people. As soon as it was possible to navigate the wide-open sea, water facilitated exploration to new lands. Later, being on these wide, open seas offered hope to millions fleeing world wars, presenting a somewhat invincible fortress protecting them from persecution, suffering and premature demise. More recently, the drowning of at least 27 men, women and children attempting to make the crossing from France to England brought into sharp focus how some things have not changed since those world wars: many are still crossing seas to flee persecution, suffering and premature demise.

In recent times, it is increasingly recognised that climate change will be a significant driver of migration. Island states such as Tonga and Micronesia already have negative net migration rates and projections are that stressed freshwater resources and water-related extreme events (such as floods) will drive more migration from island states because of food insecurity and habitat loss. Some states are already purchasing land to relocate citizens, as this is considered the only reliable adaptive response. By 2014, Kiribati had purchased 6,000 acres of forest land from Fiji: ahead of the UN climate summit that year, Anote Tong, Kiribati’s president at the time, said that buying land abroad was the way to ensure ‘migration with dignity’. Meanwhile, 6,000 km to the east, the world’s ‘first environmental refugees’ were already setting up new homes in Bougainville, an autonomous island of Papua New Guinea. They had left islands that were becoming increasingly uninhabitable as sea water ingress led to shortages in arable land and clean drinking water.

It is debatable, however, whether the islanders migrating to Bougainville are indeed the world’s first group of people forced to leave their ancestral lands due to climatic changes. Lake Chad, in west Africa was once the sixth largest inland water body, with an open water area of 25,000 km2 in the 1960s. By the 1980s, over 90% of the lake had been lost due to decreased precipitation, sparking significant internal and international migration. By 2015, more than 71,000 people from Nigeria and North Cameroon had moved towards the lake’s receding shores. As the ever-growing numbers scrambled for a portion of the limited water resources to farm, water their livestock and maintain their livelihoods, violence erupted that led to further migration out of the region. With limited non-agricultural skills and no source of capital to engage in alternative livelihood strategies the situation for these people is extremely precarious.

These two case studies challenge the narrative that climate change will drive migration in the future. They show that it already does. The situation is only likely to get worse as more regions of the world are affected, and yet, the impact of water crises on migration is not well documented.

Environmental migrants

No legal definition exists to date, for people on the move due to environmental drivers. However, the International Organisation for Migration put forward the following definition in 2007:

… persons or groups of persons who, predominantly for reasons of sudden or progressive change in the environment that adversely affect their lives or living conditions, are obliged to leave their habitual homes or choose to do so, either temporarily or permanently, and who move either within their country or abroad.

(IOM, 2007:1)

Water scarcity is bound to be a major driver of migration given that 17 countries, home to 25% of the global population, are already experiencing water stress (see Figure 1). The poorest of the global population will be the most adversely affected, but, without the necessary resources, they are also the least able to leave their homelands to seek livelihoods elsewhere. It is therefore unlikely that the world will see waves of impoverished ‘water refugees’ crossing oceans and landing on the shores of wealthy nations. The World Bank estimates that residents of poor countries are four times less likely to move than residents of middle-income countries. But their inability to move will severely impact their chances of survival.

Conceptualising water as a driver of migration

Water has always been both a push and pull factor for migration: places with adequate sources will attract migrants while diminishing reserves have the opposite effect. To assess the interconnection between water and migration, a 3D model encompassing water quantity, water quality and water-related extremes has been suggested (see Figure 2). Deterioration of water quality – for example, resulting from chemical contamination or increased salinity – will push people away from habitats due to adverse health impacts. Increased salinity can also significantly impact food security, leading to out-migration. The third factor, water extremes – such as floods or droughts – impact both quality and quantity, but their impact on the nature of migration (whether it is temporary or permanent) depends on how frequently these events occur.

Figure 2: Three-dimensional framework conceptualising the links between water and migration (Image: Nagabhatla et al., 2020).

Which way forward?

It is important to acknowledge the ways in which water migration results in unfair outcomes both for those with means to escape water-scarce areas and those without. In developing countries, wages of workers who move from rural to urban areas due to drier climates may be up to 3.4% lower than that of a typical immigrant – a significant amount for those already on a very low income. For those unable to leave their water-scarce homes, diminished food security and loss of income from agriculture present significant blows to already disadvantaged communities.

In urban areas water supplies are also under threat from climate change. Doing nothing could prove extremely costly to local and global economies, both increasing involuntary migration and severely impacting on communities without resources to fund migration. It is therefore crucial to invest in infrastructure and policies that enhance resilience within cities as well as rural areas. Water recycling, rainwater harvesting and incentives for efficient water use are tools that can be employed to this end. Evidence shows that while people may initially be resistant to using recycled water, their willingness increases when all available options are weighed up.

Finally, protecting livelihoods at the place of origin needs to be a key strategy for addressing water-induced population movement. In rural areas climate-smart agriculture can help towards reducing the vulnerability of communities and their livelihoods to diminished water resources. In Senegal, for example, high yielding, early maturing and drought resistant varieties of sorghum, millet, cowpeas and groundnuts are being developed as an adjustment to the shorter rain seasons. Traditional varieties required at least 120 days and plenty of rain to harvest, but new varieties require less than 110 days and can withstand two to three week stretches without rain. Instead of giving up farming therefore, farmers can stay on their lands and farm in ways that are adaptable to water scarcity and a variable climate.

The politics of climate justice, migration and mobility

Posted on by janet.crompton

Migration Mobilities Bristol (MMB) and the Cabot Institute for the Environment bring together researchers from across the University of Bristol to explore connections between movement and the environment from a multi-disciplinary perspective. Their diverse approaches highlight the importance of developing frames that incorporate both migration and environment, and in so doing benefit our understandings of both. Here, the directors of MMB and the Cabot Institute for the Environment introduce the blog series through the lens of the politics of climate justice, migration and mobility.

————————————-

Migration is often mobilised to illustrate the enormity of the challenge of climate change. Some Small Island States in the Pacific, for instance, may become uninhabitable with sea-level rise. Highly vulnerable countries in South Asia, including Bangladesh and the Maldives, may see large proportions of their populations forced to move because of sea-level rise, floods and salinisation of water. US climate envoy John Kerry recently fuelled fears of a future where food production collapse would force a ‘hundred million people’ to move. His comments strongly implied that even those of us who imagine we are protected from the frontline of climate change will be faced with the challenges of ‘climate refugees’ in their millions.

Moniruzzaman Sazal / Climate Visuals Countdown

Kerry’s remarks were heavily criticised, but this is not to deny that there is a connection between the world’s ecosystems and environment and human movement. It is easiest to causally relate environmental factors to migration in situations of ‘rapid onset disasters’ – destructive events that occur suddenly, such as typhoons or floods. In these situations, people move to survive, but often to a place of safety a short distance away, and they return to rebuild homes and lives once the emergency has abated. But many environmental changes are taking place over periods spanning two or three generations. ‘Slow onset’ environmental change can be a primary or contributing factor to deteriorating socio-economic conditions – increasing periods of drought, or crop yields declining rather than collapsing, for instance. In these circumstances, migration can be an important way to diversify income streams. Environmental change may also contribute to shifts in land usage and land ownership, which again may result in migration.

Declining resources can also prevent people from moving, especially when resources are slowly depleted over a generation or more. Limited access to capital can force people into illegal or exploitative migration or lead them to delay moving until forced to do so in an unplanned way – perhaps because of a rapid onset disaster that they no longer have the resilience to cope with.

The challenges faced by people who don’t move may become more severe when combined with conflict. For example, in Somalia, armed conflict has hindered the movement of pastoralists, who would otherwise relocate as a response to drought. It has also limited the possibilities of humanitarian organisations to assist them. Human mobility and environmental change are deeply interconnected but need to be understood systemically not simplistically if we are work towards climate justice.

Understanding the relationship between migration and environmental change in a more holistic and integrated way has important policy implications. For example, economic factors can mean that people migrate to places of environmental instability as well as migrating from places of environmental instability. Currently 55% of the world’s population lives in cities, and it is forecast that by 2050 this will increase to nearly 70%; nearly 60% of forcibly displaced people move to urban areas (World Bank, 2020). Many cities are extremely vulnerable to future environmental change, and already experience high temperatures, sea level rise, water stress and threats to health. Rural to urban migrants are often especially vulnerable, as they tend to move to neighbourhoods with high population density that are prone to environmental risks – think of the favelas in Rio de Janeiro and São Paulo, or the slums of Dhaka, Nairobi and Mumbai.

In these contexts, migrants, whether rural-urban or international, can be represented as an environmental problem in themselves. The movements of the poor are also represented as a root cause of problems: migration destroys carbon sinks, ‘environmental refugees’ put pressure on already scarce resources and services and so on. Rather than seeing the interconnections of human movement and climate change, the risk is that the politics of climate and the mobility of the poor – that is, ‘migration’ – are framed as oppositional. As a result, in wealthy countries we are seeing increasing tensions between politics of the environment and politics of migration, as illustrated by John Kerry’s remarks.

It is critical, then, to recognise the complexity of the connections between (human) movement and ecosystems. This new blog series, co-published by MMB and the Cabot Institute for the Environment, draws attention to some of these connections and raises questions for further research to help us understand in more depth the relationship between movement and the environment, and its political significance. The contributions in the series approach this relationship from many angles, ranging from the role of water access in shaping migration to debates around the status of the ‘environmental refugee’. One analyses the environmental footprint of home working versus office working to explore the sustainability potential of our increasing immobility. Others focus on animals and plants on the move: we have writing on the ecological context of bird migrations and on the hyper-mobility of the European eel. Meanwhile, other posts look at the movement of goods and how humans locate themselves in, and move through, landscapes of extraction and risk. In bringing together such diverse topics we hope this series will encourage new conversations about the connections between migrations, mobilities and environments.

Climate Change 2022: Impacts, Adaptations and Vulnerability – an IPCC lead author report summary

Posted on by janet.crompton

Professor Daniela Schmidt, a lead author of the recently published IPCC (Intergovernmental Panel on Climate Change)  report, Working Group II: Impacts, Adaptations and Vulnerability, recently gave an internal presentation to University of Bristol staff to summarise the report’s findings.

Recent geo-political events have meant that this report has understandably been overlooked in comparison to its predecessor, however, at 3500 pages and being the product of analysis of 34,000 papers since 2014, it is certainly not light reading. This writing aims to pinpoint and amplify the key messages from Daniela’s summary of Working Group II: Impacts, Adaptations and Vulnerability, as the Working Group III: Mitigation of Climate Change report has been released this week.

Solutions

The key take home message, was that the report offers solutions, but they are needed now. Daniela explained that it is not all doom and gloom, and it is important for our survival not to take it that way. From the report itself, the key quote, which you have perhaps seen shared elsewhere, is

The science is clear. Any further delay in concerted global action will miss a brief and rapidly closing window to secure a livable future. This report offers solutions to the world.

Nature

One of the key solutions proposed in the report is nature, both in terms of its conservation and restoration and that it offers promising solutions to many of the threats we face. For example, the potential of natural carbon sinks, coastal protection, water management and urban cooling systems has been repeatedly evidenced, as well as the importance of integrating nature and natural solutions into urban spaces.

The report stresses that humans are part of ecosystems, not separate from them, and nature is crucial to our survival because of the essential and irreplaceable ecosystem services it provides. Fragmented, polluted and overexploited ecosystems are much more vulnerable to climate change, therefore, the report stresses it is therefore important to take a coordinated approach, with their protection and restoration in mind.

Interconnection

As well as the interconnectedness of humans and nature, the report evidences previously unrealised interconnections of climate risks. Risks are becoming more complex and there are compound and cascading risks through systems. For example, in terms of food scarcity, we need to consider that heat stress will not only reduce crop yields, but also the well-being and productivity of farm workers, further exacerbating the situation. There is an increased recognition of the interconnections between people, regions, society, ecosystems, biodiversity. This means that climate change cannot be seen as an individual problem, but as one intrinsically linked with natural resource depletion, ecosystem destruction, and growing urbanisation and inequity across the world.

Equality

Another key focus of the report was the importance of but lack of global equality, which will continue to be exacerbated in the face of climate change. 3.3  – 3.6 billion live in hotspots of high vulnerability to climate change, due to high levels of poverty, limited access to water, sanitation and health services, climate sensitive livelihoods and lack of funding and accountability in government. I would like to point out, that in the vast majority of cases, it is these communities whose carbon contributions are the least, which in my opinion strongly evidences to the fact that climate change is a political problem as well as a scientific one.

Due to inequality being a big problem, the report places an emphasis on the importance of promoting equality in the solutions and with this the need to listen to marginalised voices. Daniela explained that of global climate funding, 80% goes to mitigation, or reduction of emissions, while only 20% goes to adaptation, which is likely to be what is most consequential to more vulnerable communities.

After lack of action on deals made at COP26, which scientists have already argued at best would not be sufficient to solve the problem, a continued lack of action following these urgent messages will be deeply concerning for the fate of the planet, and especially for its most vulnerable communities.

Reflections on creating equitable partnerships in research

Posted on by janet.crompton

Bristol’s Research Development International (RDI) Team works with our academics and their partners across the globe to help them secure funding for research projects. We support applications to a wide range of external funding calls including those funded as part of the UK’s Aid budget and others focused on collaborations with global South partners.

We also run internal calls to help our researchers initiate, develop and sustain international partnerships. These schemes have sown the ground for partnerships to grow their projects and to successfully secure millions in funding.

A key aspect of our internal funding schemes is the need for projects to demonstrate that the partnership is equitable. This without doubt strengthens funding proposals and ensures outcomes meet the needs of the intended beneficiaries. We have also seen equitable partnerships become more of an expectation for external funders too, especially for calls that aim to tackle global challenges.

Equitable research partnerships that enable co-design and collaboration across sectors to combine diverse sources of knowledge are crucial for enabling transformative adaptation.

Tacking Climate Change Adaptation and Resilience Opportunities, UKRI 2022

Global challenges – our principles

The University of Bristol’s principles for global challenges research activity include our commitment to build equitable relationships. We fully support these statements of expectations:

  • Partnerships should be transparent and based on mutual respect.
  • Partnerships should aim to have clearly articulated equitable responsibilities, efforts, benefits and distribution of resources.
  • Partnerships should recognise different inputs, different interests and different desired outcomes and should ensure the ethical sharing and use of data which is responsive to the identified needs of society.

Between 2017-2021 the University directly supported in excess of 120 global challenges projects with partners in over 55 countries located in the global South. These projects demonstrated the importance of investing time and resources into building equitable partnerships which are based on trust and understanding. The funding enabled researchers to gain and develop first-hand knowledge about how to develop inclusive partnerships where cultural differences are considered and understood. It also helped them to recognise that there are power dynamics within partnerships that are sometimes out of their control, for example the particular model of funding or Bristol’s own institutional processes. Others arise due to a lack of awareness of the local contexts in which overseas partners operate.

Developing international research collaborations

When we asked some of our award holders what advice they would give to researchers who would like to develop international global challenges research collaborations they commented:

“I think you have to go and visit and sit down and spend time talking, understanding perspectives, priorities, and local constraints.  There are constraints that if you are based in the UK, you don’t even know are possible constraints, until you are there.  People have got to like you, to feel you ‘hear’ them and are interested and understanding.”

“The basic element of overseas partnerships is to be respectful of your partners and recognise that they come with substantial technical expertise and understand their context far better than an overseas researcher will.  It is crucial to listen to the partners and be willing to change you own ideas and plans in light of the inputs, insights and advice from the partners.”

“Communication was often difficult in the early stages of our partnership.  If considering new partnerships again, I would ensure that we had more extensive discussions at the start about capacity, capability, and areas of particular interest so we maximise the likelihood that research designs match partner expectations”

“Recognise that the drivers for academics in other countries may not always be the same as those in the UK – your partners may care much more about community interaction or policy engagement than writing papers for instance.”

“Co-development and collaboration creates new possibilities in terms of outcomes and impact that are not possible alone – be patient and flexible with partners and processes that are needed to build these collaborations because the rewards can be significant.” 

How to find international research partners

If you are interested developing an international research collaboration, your first question may be how do I find an international partner(s)?   Some of our suggestions include:

  • Seek advice from your School Research Director or Faculty International Director;
  • Contact your research support colleagues who may be aware of existing projects working in a similar area and can put you in touch with your colleagues.
  • Speak to your institutions research institutes and centres. These are often closely linked to institutions’ international engagement strategies and can enable interdisciplinary links within the institution that can lead to developing international collaborations.
  • Like Bristol, your institution may be part of an existing international network, such as the Worldwide Universities Network (WUN).  Contact the network’s team to find out what partnerships exist already and whether they can facilitate links with these institutions
  • The South West International Development Network (SWIDN) is a cross-sector membership organisation of non-profit, academic institutions, businesses, consultants and individuals who are working in international development towards the SDGs. Your institution may have connections to similar organisations. If you are seeking partners for your research, they can share information with their NGO members.

What help does the RDI team provide to University of Bristol researchers and their international partners?

Our activities include discussing potential projects and how these fit with specific call requirements; how to complete applications, the information to be included and who in the University can provide additional support; how to generate impacts and policy; identifying potential future funding streams for sustaining partnerships; reviewing draft applications; assisting or signposting in respect of the associated administrative, financial and contractual requirements. We have also developed a toolkit to help Bristol researchers navigate all these aspects.

Hints and tips for global challenges research

Do

  • take time to build your partnerships.  Successful partnerships are built on trust and understanding.  Look out for funding streams which will help you to meet them face to face.
  • make sure the project is co-designed, it should be informed by the local contexts of the challenges(s) identified by partners and other stakeholders.
  • consider the potential for mutual learning and knowledge exchange.
  • recognise and understand that what you may think is a primary issue in a partner country, might not be a burning issue from your partner’s perspective.
  • think about cultural differences and how you will need to accommodate or address these as the project develops.
  • think about how time differences and different pressures may impact on how your project develops.
  • be aware that funding deadlines are often very short for global challenges research and applications can take a considerable time to complete
  • be aware that these funding streams are competitive.

Don’t

  • try to shoehorn your research to meet the aims of a particular call. Funding panels can usually spot where this is the case.
  • assume that professional services teams will be able to prioritise your application.  Liaise with them at an early stage in your planning. Take time to become familiar with the University’s research costing systems and the associated procedures in place.
  • assume that your University’s due diligence and contractual processes will always be straightforward and timely. These can be complex in some instances, especially where your partner(s).

Climate change: effect on forests could last millennia, ancient ruins suggest

Forests are home to 80% of land-based biodiversity, but these arks of life are under threat. The rising average global temperature is forcing tiny plants like sidebells wintergreen on the forest floor (known as the understory) to shift upslope in search of cooler climes. Forest plants can’t keep up with the speed at which the climate is changing – they lag behind.

The pace at which forests adapt to changing conditions is so slow that species living in forest understories today are probably responding to more ancient changes in their environment. For instance, the Mormal Forest floor in northern France is, in several places, covered by a carpet of quaking sedge. This long grass-like plant betrays the former settlements of German soldiers who used it to make straw mattresses during the first world war.

Changes in how people managed the land, sometimes dating back to the Middle Ages or even earlier, leave a lasting fingerprint on the biodiversity of forest understories. Knowing how long the presence of a given species can carry on the memory of past human activities can tell scientists how long climate change is likely to have an influence.

Ecologists are turning to technologies such as lidar to rewind the wheel of time. Lidar works on the same principles as radar and sonar, using millions of laser pulses to analyse echoes and generate detailed 3D reconstructions of the surrounding environment. This is what driverless cars use to sense and navigate the world. Since the late 1990s, lidar has enabled amazing discoveries, such as the imprints of Mayan civilisation preserved beneath the canopy of tropical forest.

In a new paper, I, along with experts in ecology, history, archaeology and remote sensing, used lidar to trace human activity in the Compiègne Forest in northern France back to Roman times – much later than historical maps could ever do.

Illuminating ghosts from the past

Compared to farm fields, which are ceaselessly disturbed, forest floors tend to be well-preserved environments. As a result, the ground below the forest canopy may still bear the imprints of ancient human occupation.

Archaeologists know this pretty well and they increasingly rely on lidar technology as a prospecting tool. It allows them to virtually remove all the trees from aerial images and hunt artefacts hidden below treetops and fossilised under forest floors.

Using airborne lidar data acquired in 2014 over the Compiègne Forest in northern France, a team of archaeologists and historians found well-preserved Roman settlements, farm fields and roads. Long considered a remnant of prehistoric forest, the Compiègne was, in fact, a busy agricultural landscape 1,800 years ago.

A closer look at these ghostly images of the Compiègne Forest reveals several depressions within a fossilised network of Roman farm fields. Archaeologists excavated numerous depressions like this across many forests in north-eastern France and found that people from the late iron age and Roman era carved them.

These depressions were made to extract marls (lime-rich mud) to enrich farm fields in carbonate minerals for growing crops and to create local depressions where rainwater collects naturally for livestock to drink. Marling is still a widespread practice in crop production in northern France.

The long-lasting effects of human activity

These signs of Roman occupation in modern forests provide clues to why some plant species are present where we wouldn’t expect them to be.

On a summer day in 2007 in a corner of the Tronçais Forest in central France, a team of botanists found a little patch of nitrogen-loving species – blue bugle, woodland figwort and stinging nettle – nestled among more acid-loving plants.

Nothing special at first sight. Until archaeologists found that Roman farm buildings had once stood in that spot, with cattle manure probably enriching the soil in phosphorous and nitrogen.

If a clutch of tiny plants can betray ancient farming practices dating back centuries or millennia, ongoing environmental changes, such as climate change, will have similarly long-lasting effects. Even if the Earth stopped heating, the biodiversity of its forests would continue changing in response to the warming signal, in a delayed manner, through the establishment of more and more warm-loving species for several centuries into the future.

Just as the Intergovernmental Panel on Climate Change has a mission to provide plausible scenarios on future climate change, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services aims to provide plausible scenarios on the fate of biodiversity. Yet none of the biodiversity models so far incorporate this lag effect. This means that model predictions are more prone to errors in forecasting the fate of biodiversity under future climate change.

Knowing about the past of modern forests can help decode their present state and model their future biodiversity. Now lidar technology is there to help ecologists travel back in time and explore the forest past. Improving the accuracy of predictions from biodiversity models by incorporating lagging dynamics is a big challenge, but it is a necessary endeavour for more effective conservation strategies.

Low-technology: why sustainability doesn’t have to depend on high-tech solutions

Posted on by janet.crompton

 

Encouraging recycling is part of the low-tech approach to life.

It’s a popular idea that the path to sustainability lies in high-tech solutions. By making everyday items like cars electric, and installing smart systems to monitor and reduce energy use, it seems we’ll still be able to enjoy the comforts to which we’ve become accustomed while doing our bit for the planet – a state known as “green growth”.

But the risks of this approach are becoming ever clearer. Many modern technologies use materials like copper, cobalt, lithium and rare earth elements. These metals are in devices like cell phones, televisions and motors. Not only is their supply finite, but large amounts of energy are required for their extraction and processing – producing significant emissions.

Plus, many of these devices are inherently difficult to recycle. This is because to make them, complex mixes of materials are created, often in very small quantities. It’s very expensive to collect and separate them for recycling.

Among others, these limitations have led some to question the high-tech direction our society is taking – and to develop a burgeoning interest in low-tech solutions. These solutions prioritise simplicity and durability, local manufacture, as well as traditional or ancient techniques.

What’s more, low-tech solutions often focus on conviviality. This involves encouraging social connections, for example through communal music or dance, rather than fostering the hyper-individualism encouraged by resource-hungry digital devices.

“Low-tech” does not mean a return to medieval ways of living. But it does demand more discernment in our choice of technologies – and consideration of their disadvantages.

Origins of low-tech

Critics have proclaimed the downsides of excessive technology for centuries, from 19th century Luddites to 20th century writers like Jacques Ellul and Lewis Mumford. But it was the western energy crisis in the 1970s that really popularised these ideas.

British economist E.F. Schumacher’s 1973 book Small is Beautiful presented a powerful critique of modern technology and its depletion of resources like fossil fuels. Instead, Schumacher advocated for simplicity: locally affordable, efficient technologies (which he termed “intermediate” technologies), like small hydroelectricity devices used by rural communities.

Schumacher’s mantle has been taken up by a growing movement calling itself “low-tech”. Belgian writer Kris de Dekker’s online Low-Tech Magazine has been cataloguing low-tech solutions, such as windmills that use friction to heat buildings, since 2007. In particular, the magazine explores obsolete technologies that could still contribute to a sustainable society: like fruit walls used in the 1600s to create local, warm microclimates for growing Mediterranean fruits.

In the US, architect and academic Julia Watson’s book Lo-TEK (where TEK stands for Traditional Ecological Knowledge) explores traditional technologies from using reeds as building materials to creating wetlands for wastewater treatment.

And in France, engineer Philippe Bihouix’s realisation of technology’s drain on resources led to his prize-winning book The Age of Low Tech. First published in 2014, it describes what life in a low-tech world might be like, including radically cutting consumption.

Bihouix presents seven “commandments” of the low-tech movement. Among others, these cover the need to balance a technology’s performance with its environmental impact, being cautious of automation (especially where employment is replaced by increased energy use), and reducing our demands on nature.

But the first principle of low-tech is its emphasis on sobriety: avoiding excessive or frivolous consumption, and being satisfied by less beautiful models with lower performance. As Bihouix writes:

A reduction in consumption could make it quickly possible to rediscover the many simple, poetic, philosophical joys of a revitalised natural world … while the reduction in stress and working time would make it possible to develop many cultural or leisure activities such as shows, theatre, music, gardening or yoga.

Ancient solutions

Crucially, we can apply low-tech principles to our daily lives now. For example, we can easily reduce energy demand from heating by using warm clothes and blankets. Food, if it’s packaged at all, can be bought and stored in reusable, recyclable packaging like glass.

Architecture offers multiple opportunities for low-tech approaches, especially if we learn from history. Using ancient windcatcher towers designed to allow external cool air to flow through rooms lets buildings be cooled using much less energy than air conditioning. And storing heat in stones, used by the Romans for underfloor heating, is being considered today as a means of dealing with the intermittency of renewable energy.

Design and manufacture for sustainability emphasises reducing waste, often through avoiding mixing and contaminating materials. Simple materials like plain carbon steels, joined using removable fasteners, are easy to recycle and locally repair. Buses, trains and farm machinery using these steels, for example, can be much more readily refurbished or recycled than modern cars full of microelectronics and manufactured from sophisticated alloys.

In some places, the principles of low tech are already influencing urban design and industrial policy. Examples include “15-minute cities” where shops and other amenities are easily accessible to residents, using cargo bikes instead of cars or vans for deliveries, and encouraging repairable products through right-to-repair legislation in the EU and US.

Meanwhile, in Japan, there’s emerging interest in the reuse and recycling practices of the Edo period. From 1603 to 1867, the country was effectively closed to the outside world, with very limited access to raw materials. Therefore, extensive reuse and repair – even of things such as broken pottery or utensils with holes that we’d now regard as waste – became a way of life. Specialist repairers would mend or recycle everything from paper lanterns and books to shoes, pans, umbrellas and candles.

By following examples like these, we can make discerning technological choices a central part of our search for sustainable ways of living.The Conversation

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

Posted on by janet.crompton

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

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

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

How plants evolved

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

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

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

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

Old genes and new tricks

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

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

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

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

Planting for the future

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

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

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

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

Posted on by janet.crompton

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

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

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

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

What to plant in spring

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

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

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

What to plant in summer

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

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

What to plant in autumn

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

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

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

What to plant in winter

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

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

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

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

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

Drone Ecologies: Exploring the opportunities and risks of aerial monitoring for biodiversity conservation

Posted on by janet.crompton

Drones, also known as unmanned [sic] aerial vehicles (UAVs), are becoming an increasingly common technology within conservation, with uses ranging from mapping vegetation cover, to detecting poachers, to delineating community land claims. Drones are favoured as they’re cheaper and simpler than rival remote sensing technologies such as satellites, yet despite their benefits, they pose a number of issues regarding personal privacy rights and can be difficult to navigate in environments like dense forests. Moreover, as social scientists have previously highlighted, monitoring technologies such as drones have the potential to be used for covert surveillance in conservation areas as part of what they call ‘green securitisation’ (Kelly and Ybarra, 2016; Massé, 2018). To date, however, there has been limited discussion between drone practitioners and scientists across disciplines regarding what a drone can do, and how it is done.

This was the inspiration behind Drone Ecologies, an online workshop hosted by the University of Bristol on the 5th and 6th of July 2021. With over 60 participants representing various disciplines across the social and natural sciences, as well as experts from the arts, industry, and NGOs, the workshop aimed to create an open space for important interdisciplinary dialogues concerning the use of drones for conservation purposes. Through a series of panels, presentations, and breakout activities, we discussed the technical, operational, and analytical dimensions of drones, as well as the ethical, political, and sociocultural impacts of introducing drones and other monitoring technologies into conservation spaces. This essay offers an overview of the conversations that took place during the workshop, and we invite others to take part in these ongoing discussions.

Our opening panel explored some of the operational benefits of drone technologies for environmental researchers. Drones can provide optical coverage over large areas with high spatial and temporal resolution, and have been successfully deployed to monitor various wildlife populations; assess changes in land cover; and map human-landscape interactions. However, with an increase in the technical capabilities of both drones and the sensors they carry, drones are becoming more than just airborne cameras. They can now be used to monitor other environmental components—e.g. noise, air pollution, and pollen levels—opening the door for new and diverse forms of data generation and analysis. Another emerging feature with huge potential for data collection is the integration of drones with other devices as part of the Internet of Things (IoT). Networks of coordinated drones that are able to share information and react in real-time could become instrumental in new anti-poaching efforts and for long-term, large-scale environmental monitoring.

Alongside a discussion of the advantages that drones provide for researchers and state agencies, much attention was given to the ways in which drones may be used to benefit local communities by, for example, monitoring forest fires within their concessions, or by demonstrating sustainable forest stewardship. Speakers such as Jaime Paneque-Gálvez and Nicolás Vargas-Ramírez from the National Autonomous University of Mexico showed how several community-based projects in South and Central America successfully utilised low-cost drones for participatory mapping processes. The researchers presented their experiences in teaching peasant and Indigenous communities in Mexico, Bolivia and Peru how to pilot and maintain drones, and how to incorporate drone-based imagery and orthomosaics into GIS products. These high-resolution, geo-referenced maps could then be used as evidence for territorial claims, or to expose environmental damage to forests and rivers. The use of drones granted the communities access to greater levels of spatial and temporal resolution with lower financial barriers, as well as greater degrees of inclusivity and autonomy over data collection when compared to satellite products.

Despite the logistical advantages of drones, there are still drawbacks regarding their use in environmental monitoring. Although they may reduce some environmental disturbances associated with monitoring—e.g. the cutting of tracks for transects—they also introduce new concerns, such as acoustic disturbance to wildlife under observation (and otherwise). However, some of the biggest concerns discussed during the second panel of the workshop were the negative impacts that drones may have on the communities living in and around the conservation areas being monitored. Trishant Simlai, a PhD candidate at the University of Cambridge, gave a plenary presentation showing how drones in India, along with other technologies used for conservation monitoring, form part of a deliberate system of surveillance and harassment of forest communities by the forestry department, exacerbating local inequalities along lines of class, caste, and gender, and producing ‘atmospheres’ of control. The second panel’s presentations also highlighted how, regardless of the operator’s intent, communities and individuals alter their behaviour when monitoring technologies are deployed by, for instance, avoiding areas that may have previously provided refuge and privacy.

During a group dialogue on green securitisation, Boise State University’s Libby Lunstrum posited several key observations on drones which formed the basis of ongoing conversations. Firstly, the militaristic origin of drone technologies raises concerns about the complicity of drone use with broader shifts towards militarised conservation and human rights violations. Secondly, unlike the cases presented by Paneque-Gálvez and Vargas-Ramírez, underlying power relations may mean that drone technologies are not always truly accessible for all community members. There are also epistemic concerns regarding the relationship between the disembodied and ‘objective’ knowledge purportedly produced by drones and the embodied and situated forms of knowledges produced by other, on-the-ground methods. Finally, there are a range of critical questions concerning the political economy of drone production: who is investing in these technologies? How do militarised actors participate in conservation, at times greenwashing harmful practices against local communities? How are drones complicit with these dynamics, and how do we reconcile that with their positive uses?

Given the above considerations, and the increasing use of drones for data collection, much of the final discussion at the workshop focused on the ethical implications of using drones within conservation. Drawing inspiration from Sandbrook et al.’s (2021) recent paper on the socially responsible use of conservation monitoring technology, we amended the guidelines set out in their paper to be specifically applicable to drones. Some key concerns included issues of proportionality—whether drones are always necessary tools for conservation practices—and the importance of recognising and foreseeing the potential for social implications in the first place. These concerns, we believe, are often obscured by the techno-optimism that surrounds drones, alongside a generally prevalent faith in technological solutions to conservation problems.

By the end of the workshop, it was clear that the use of drones for conservation purposes is a complex matter, and their use is subject to many conflicting ideas. Drones configure power relations in which social, political, and economic asymmetries and vulnerabilities can be exacerbated. However, drones can also be used for environmental justice purposes and can aid in the reduction of inequalities when their use is democratised and appropriate for local communities. The workshop also revealed some of the networks, assemblages, and ecosystems that drones inhabit, and that constitute power relations in which drones could play a role. It is important that these networks of relationships and interests that mobilise drones and other complementary technologies—e.g. satellite images—are made explicit, so that we can understand new configurations of power that are developing and identify those who benefit from the introduction of drones.

Additionally, the workshop also highlighted the relevance of multi- and interdisciplinary dialogues in understanding and developing the use of drones and other types of monitoring technologies for conservation purposes. We believe that it is important for these interdisciplinary networks to be established, and to continue exploring the complex impacts that drones have on environments, humans, and conservation practices. The interdisciplinarity approach simultaneously engages different disciplinary approaches and ethics, mitigating any blind spots within research and fully illuminating any potential damage or disturbances arising from drone use. This workshop marked an opening of these dialogues which we hope will continue within this emerging space, building towards the development of cross-disciplinary guidelines and policies for the ethical and responsible use of drones in conservation.

Energy landscapes and the generative power of place

Posted on by janet.crompton

Spring 2020 will be remembered for the global Covid-19 pandemic. While in Britain people  were ordered to stay at home in a national lockdown, the nation also experienced its longest run of coal-free energy generation since the Industrial Revolution – 68 days of coal-free power. This wasn’t unconnected: as the economy shrunk almost overnight some of the major industrial energy uses stopped; steady low usage meant that the ‘back-up’ coal-fired generators of the national grid weren’t needed. Nor was this fossil-free: oil, alongside nuclear and gas, continued to fuel power plants. But, more than ever before, our energy was produced by renewable sources, and on 26 August 2020, the National Grid recorded the highest every contribution by wind to the national electricity mix: 59.9%.

This shift out of fossil dependence is both a historic moment, and the product of historical processes. The technological and scientific work that underpins the development of efficient turbines has taken decades – and it is what I’ve written about in my article, ‘When’s a gale a gale? Understanding wind as an energetic force in mid-twentieth century Britain’, out now in Environmental History. I look at how interest in the wind as a potential energy source (by the British state, and state scientists), generated the need for knowledge about how wind worked. Turbine technology needs airspace to operate, but it also needs land – to ground the turbines in, to connect to the grid by – and people to install and operate the devices. And so when looking at energy landscapes, we really need to think beyond the technology and consider the people and places with which it interacts,  to understand how energy is produced and used.

Hauling wind measuring equipment up Costa Hill, Orkney. In E.H. Golding and A.H. Stodhart, ‘The selection and characteristics of wind-power sites’ (The Electrical Research Association, 1952). Met Office Archive.

This was certainly the case for understanding wind energy. In 1940s and 50s Britain, scientists surveyed the wind regime at a national scale for the first time. They relied on the help and cooperation of local people to do this. In the brief mentions of this assistance in the archival record, we gain insight into the importance of embodied, localised knowledge in scientific processes which can at first seem detached from the actual landscapes of study.

The surveys determined Orkney as the best place to situate a test turbine. Embodied knowledge, knowledge that is learnt from being in place and from place, is very tangible in accounts of a hurricane which hit Orkney in 1952, during the turbine tests. By looking at how the islanders made sense of a disastrous wind, and brought the turbine technology into their narratives of the storm, we learn that it is not only electricity generated by the development of renewable energy, but also new dimensions to place-based knowledge and identities.

Seeing beyond the technology to consider its interactions with environments and societies is something that the energy humanities considers as essential. I’ll be working on this subject from this perspective for some time to come, and would love to hear your thoughts on the article.
