Antarctica: Ship life

Posted on by janet.crompton
The RRS James Clark Ross docked in the Falkland Islands

Blinking blurry eyes, I crack open the curtains and gaze out into the bright light of a new day. A hulking white and blue iceberg gazes back at me. Even after a broken night’s sleep being shunted from one side of my bunk to the other as the ship bounces through swell, that still makes a rewarding start to each day. Through an unexpected turn of events, I’ve found myself on the British Antarctic Survey’s RRS James Clark Ross, on a seven-week long research cruise helping researchers from the University of Exeter take samples and measure CFCs in the Weddell Sea. Having just handed in my PhD thesis – after four years of studying and researching Antarctic climate and hearing the question “do you get to go to Antarctica?” countless times – the opportunity to help out on this cruise was too good an opportunity to pass up. Life on a ship gives you plenty of time to think (and write), but I promise to keep these musings brief in three posts: ship life; the science and why we’re here; and how the real thing compares to a PhD. 
—————————————-
This is my first experience of life on a ship. Previously, my most extensive experience of boat life was the eight hours on the Stena Line from Liverpool to Belfast, so I shall use that as my reference frame. Stena Line regularly ask you to fill out feedback forms and rate your experience to have the chance to win back the cost of your trip, so I shall do the same here (although as usual I don’t expect to win anything).

How did you find the booking procedure?

Stena Line have a fast and efficient website for making and managing bookings. Signing up for the research cruise was also pretty straight forward, although that was likely aided by me having done a PhD in Antarctic-related science and knowing someone at the British Antarctic Survey (BAS) who forwarded me the advert. I emailed the lead scientist from Exeter saying I was interested, we had a chat on Skype then I had to confirm that my PhD supervisors at Bristol were happy for me to go.

Generally, however, beyond that point there was a bit more faff than booking the Stena Line. BAS require quite a few forms filling out, some of which require a bit more homework, including passing a medical examination and a sea survival course. The authentic personal sea survival certificate had to be presented on getting on the boat before sailing. In contrast, the Stena Line rarely even ask for ID (although I suppose this might change after Brexit).

How did you find the check-in procedure?

The check-in for the Stena is remarkably simple, and as mentioned they rarely even ask for ID. Getting onto the James Clark Ross was logistically more complicated, requiring flights from Heathrow to Madrid, Madrid to Santiago in Chile, and Santiago to Punta Arenas. Although this journey took more than 24 hours, I still preferred it to driving in the rain up the M5 and M6 from Bristol, as I got free food and could watch films. Punta Arenas is also nicer than Birkenhead and I found the language barrier easier to overcome in Chile (Scouse can be very confusing at times).

How did you find the cabins (if applicable)?

Getting a cabin on the Stena Line is not necessary, particularly if travelling during the day time sailing. The last time I travelled on the night time crossing, however, the cabin was not overly satisfactory with uncomfortable beds, an unclean bathroom and a broken soap dispenser. Stena customer services subsequently refunded the cost of the cabin. On the James Clark Ross, the cabins are slightly smaller than the Stena Line, however, there is ample storage space, the beds are pretty comfortable and there are privacy curtains for each bunk, which is good when you are on slightly different work shifts to your roommate. The biggest complaint about the James Clark Ross is that it makes many strange noises and rocks a lot more in the heavy weather, which can keep you up a lot of the night. These noises include a high-pitched wail which is either the stabiliser system or sirens luring us to our watery graves. The latter seems more likely.

How did you find the food onboard?

The Stena’s Met Grill is renowned for its fried breakfast and hearty lunch and dinner menu. The portion sizes are good, however, the prices are also a bit steep. On the James Clark Ross, three square meals a day are available (including midnight dinner service for those on night shifts), with lunch and dinner both offering 3+ courses. Because of how my shift patterns work out, it doesn’t make sense to get up for breakfast, so I just eat a 3-course lunch and dinner each day. Remarkably, over 4 weeks since we left, there is still fresh fruit and some salad on the go. The variety has been good, and they also have included some of the classics off the Stena Line menu, including fish and chips (most Fridays), curry (every Saturday) and Swedish meatballs. Although I have also had Swedish meatballs on the Stena, I have never tried authentic (Ikea) Swedish meatballs to know which is closer to the real deal.

How did you find the onboard shopping?

The shop onboard the Stena Line is pretty awful. They sell head phones if you forgot yours, which is about the only thing I have ever bought from it. They also sell some magazines and over-priced toys in case you didn’t realise the crossing was 8 hours and find yourself going slightly insane. The shop on the James Clark Ross, called the bond, is stocked with James Clark Ross branded clothing, toiletries, chocolate bars and some odds and ends like postcards and plaques. Unfortunately, as the ship is nearing the end of its working life for BAS, being replaced next year by the RRS Sir David Attenborough (of Boaty McBoatface fame), none of the branded clothing is being restocked. That means the only things that are left are in sizes XXL or age 7-8, neither of which are much use to me.

How did you find the onboard entertainment and facilities?

Both ships have a bar. The James Clark Ross bar is extremely cheap, however, many of the beers are about six months past their best before dates, which can result in ‘bowel roulette’ the following day. A worthwhile sacrifice if you’re unemployed like me. The lounge area is remarkably similar between both boats and is comfortable enough. The internet connection is much better on the Stena, although they possibly harvest your personal data in the process of providing it. On the James Clark Ross, they have to commit some of the internet to facilitate the science (boring), so the bandwidth for personal connections is not as strong.

Besides the gambling machines, the Stena Line’s main attraction is the cinema, which can be good if they have a decent film being shown. On the James Clark Ross, although they do not have a dedicated cinema room, they have a huge selection of DVDs and an endless supply of films available on people’s laptops which can all be put through a projector. There are also loads of board games and a few musical instruments onboard too, which are nice to have a jam on and facilitated a St Patrick’s Day gig and ceilidh dance. Although the James Clark Ross has a greater range of entertainment available, the Stena Line only has to keep you amused for 8 hours, not 7 weeks, so this one is a tight run context. Luckily when you have to work 12 hour shifts, you don’t have much time for entertainment.

Would you recommend this crossing to a friend?

Usually my answer to this is ‘yes’ for the Stena Line. It’s a handy way of getting to England from Belfast, saving the drive through North Wales and up from Dublin. Admittedly there’s not much to see in the Irish Sea except the odd shearwater and the Isle of Mann, but generally the crossing is smooth because of the size of the ship (around 185m long) even when the weather is bad. On the James Clark Ross, the research cruise route very much agrees with the old saying ‘The adventure is in the journey, not the destination’. We are analysing a transect through the Southern Ocean and Weddell Sea and end at 57.5°S, 30°E, which is precisely in the middle of nowhere (go ahead and look it up on Google Maps). Although we don’t end anywhere in particular, the route has been spectacular at times: we’ve sailed past a number of sub-Antarctic islands, countless colossal icebergs, seen penguins on land, in the sea and on ice, had dolphins, fin whales, and humpbacks right by the ship (the latter breaching dramatically at times) and had regular, effortless fly-bys from wandering albatrosses and other seabirds great and small. The weather has been mixed and as the ship is 100m long it feels the swell a bit more than the Stena, however, the seas so far have been much more merciful than I had expected.

As exciting as it is to see the Isle of Mann and the Mourne Mountains, on the whole, I would say Antarctica just about tops the Irish Sea. Sorry Stena Line. Although, for health and safety reasons I’m sure the crew of the Stena Mersey are happy enough to not have to dodge all of these icebergs.

Interrogating land and water use change in the Colombian Andes

Posted on by janet.crompton

Socio-ecological tensions, farming and habitat conservation in Guantiva-La Rusia

Highlighting the Cabot Institute’s commitment to growing the evidence base for water-based decision making, Dr Maria Paula Escobar-Tello (Co-Investigator) and Dr Susan Conlon (Post Doctoral Research Assistant) introduce the social science component of an exciting three-year project called PARAGUAS, an interdisciplinary collaboration between UK and Colombian researchers to investigate how plants and people influence the water storage capacity of the Colombian Páramos…

In June 2018, the Natural Environment Research Council (NERC) and the Arts and Humanities Research Council (AHRC) jointly awarded funding to five UK projects under the Newton-Caldas funded Colombia-Bio programme. The Colombian Department of Science, Technology and Innovation (Colciencias) subsequently awarded funding to 24 smaller Colombian projects under the same programme. PARAGUAS – How do the Páramos store water? The role of plants and people” is one of the five UK-funded projects.

Crucial source of land and water

The páramos are tropical mountain wetlands found between 3000m and 4500m of elevation in the Andes. Known for their extreme water storage and regulation capacity, they generate exceptionally high and sustained water supplies to farmland, settlements and cities downstream. They are also an important repository of biodiversity. Páramos have been historically inhabited; first by pre-Colombian indigenous communities and nowadays by heterogeneous campesino communities who depend on them as a primary source of water crucial for their livelihoods and wellbeing.  In the last few decades, several political, economic and armed conflict dynamics have pushed the agricultural frontier to increasingly higher elevations. The combined pressure of land use and climate change has already degraded many páramo areas and their potential demise has generated widespread concern across all levels of governance in Colombia, as well as within the NGO sector and research community.

Growing tensions in water conservation

A diversity of actors – government, NGO, community organisations, farmers – are interacting in the conservation of water in the Guantiva-La Rusia páramo, each with their own knowledges and understandings of the water storage function of the páramo, as well as contrasting views on who should benefit from this function and on the political economy of conservation efforts. Our team began to explore two sets of dynamics where these contrasting views were manifest during a pre-fieldwork campaign in January 2019.

In the first dynamic, local populations experience national and regional conservation efforts to address land and water degradation through the delimitation of the páramos – a controversial ongoing land management process whereby government authorities seek to map the areas they believe should be conserved to protect the páramos. One approach in these new land management policies and plans is to extend national park land under protection through land acquisition, which overlaps with complex pre-existing land ownership arrangements. In addition, the Ley de Páramos 233, 2018 (Páramos Law 233) prohibits farmers from carrying out productive activities on formerly-used land, which is now defined as páramos by authorities, and tasks local authorities with negotiating with farmers and supporting them in finding alternative economic activities.  While this ban may sound ecologically necessary, multiple actors question the processes that have defined the páramo borderline for several reasons including its implications on farmers’ livelihoods, identities and ecosystem knowledges.

In the second dynamic, water conservation policies and plans prioritise the channelling of water from the páramos to the aqueducts that supply the populations downstream through land purchases that lead to changes in land use and the piping of springs and streams. These processes are equally contested and have led to community-level forms of organisation, representation and resistance; as well as to multi-scale and multi-issue conflicts between different campesino sectors; between local, regional and national-level political and environmental authorities; and between different discourses about environmentalism and modernisation.

Our project goals

As the social science component of PARAGUAS, we want to explore these different sets of socio-cultural and political tensions. We will do this by investigating how and why land and water use has changed in the Guantiva-La Rusia páramo and how this is related to public policy decisions that have shaped (or not) how local páramo inhabitants, particularly crop and livestock farmers, interact currently with the páramo through their day-to-day farming practices. Our aim for this part is to expose lesser heard voices in the conservation debate and listen to how local inhabitants articulate their understanding of the water regulation function of the páramo.

We are busy preparing for the first round of fieldwork in May 2019 and are designing our methodology of interviews, focus groups and digital storytelling techniques in close collaboration with our colleagues at Loughborough University. Watch this space for further updates!

World Water Day: How can research and technology reduce water use in agriculture?

Posted on by janet.crompton

World Water Day draws attention to the global water crisis and addresses why so many people are being left behind when it comes to having access to safe water. The UN estimates that globally 80% of people who have to use unsafe and unprotected water sources live in rural areas. This can leave households, schools, workplaces and farms struggling to survive. On farms water is vital for the production of food and is used in a huge range of processes, including irrigation and watering livestock. In this blogpost I will lightly review the current issues around water in agriculture and highlight some exciting research projects that may offer potential solutions.

What is the water crisis?

The UN Sustainable Development Goal 6 is to ensure that all people have access to sustainable, safe water by 2030. Unfortunately, we’re a long way off achieving this goal as a recent report from UNICEF/WHO estimates that there are currently 2.1 billion people living without access to safe water in their homes and workplaces. Another report estimates that 71% of the global population experiences severe water scarcity during at least one month of the year. In recent years we have seen water risks increase, with severe droughts in Africa, China, Europe, India and the US. In sub-Saharan Africa, the number of record breaking dry months increased by 50% from 1980 to 2013. Unfortunately droughts, floods and rising sea levels are predicted to continue and become more unpredictable under climate change scenario models and as the global population continues to grow, there will be increasing demands on water supplies. Increases in water scarcity are likely to lead to increases in political and economic instability, conflict and migration.

Why is water important to agriculture?

In agriculture, water is vital for growing crops and sustaining livestock. Farmers use water to irrigate, apply pesticides and fertilizer and protect from heat and frost. This heavy reliance means that when water supplies run out, farmers are unable to effectively maintain their crops and livestock, leading to food insecurity. Drought stress can result in yield losses of 64% in rice, 50% in chickpea, 18 – 32% in potato. Drought has particularly devastating effects in tropical and sub-tropical regions, where climate change is predicted to have the biggest impact.

The amount of water it takes to produce food and drink products is pretty shocking. Beef production in particular is associated with high levels of water usage. It is estimated that the global average water footprint of a 150g beef burger is 2350 litres; despite producing just 5% of the world’s food calories, beef production is reported to create 40% of the water scarcity burden. Although there are big variations in the environmental impacts of beef farming, with grassland fed, rotational systems being less intensive than grain fed herds on deforested land.

Where does water used for agriculture come from?

The water that is used in agriculture comes from a range of sources, including surface and ground water supplies, rivers and streams, open canals, ponds, reservoirs and municipal systems. Globally, the FAO estimates that agriculture accounts for 70% of freshwater withdrawals, which is predominately used for irrigation. In many areas the high level of groundwater used for irrigation is unsustainable, leading to depletion. For instance, the OECD estimates that groundwater supplies 60% of India’s agricultural water needs but groundwater sources are suffering from depletion and pollution in 60% of states. A big problem is that irrigation is often highly inefficient; in the US the FAO estimates that the amount of irrigated water that is actually used by plants is only 56%. Large amounts of energy are also needed to withdraw, treat and supply agricultural water, leading to significant greenhouse gas (GHG) emissions.

What happens to agricultural water after use?

As well as depleting freshwater supplies, agriculture can also pollute them, with runoff containing large quantities of nutrients, antibiotics, growth hormones and other chemicals. This in turn has big affects on human health through contamination of surface and ground water with heavy metals, nitrate and pathogens and in the environment; it can cause algal blooms, dead zones and acidification of waterways. Combined these issues mean that better management of water in agriculture has huge potential for improving sustainability, climate resilience and food security, whilst reducing emissions and pollution.

What are the potential solutions?

Thankfully there are many innovative projects that are working to improve issues around water in agriculture. Below are a few examples that I find particularly promising.

How can technology help?

To reduce water wastage on farms, agri-technology is being developed whereby multiple wireless sensors detect soil moisture and evapotranspiration. The sensors feed this information to a cloud-based system that automatically determines precisely how much water to use in different parts of the field, leading to increased yields and saving water. Farmers can get water management recommendations via a smartphone app and the information automatically instructs irrigation systems. At a larger scale, these data systems can feed into a regional crop water demand model to inform decision-making on agricultural policies and management practices, and to provide early warnings of potential flood and drought risks.

Irrigation systems are also being made more efficient; one study found that simply changing from surface sprinklers to drip irrigation that applies water directly to plant roots through low-pressure piping, reduced non-beneficial water wastage by 76%, while maintaining yield production. In arid areas these systems can be used for a technique called partial root drying, whereby water is supplied to alternate side of the roots, the water stressed side then sends signals to close stomatal pores which reduces water lost through evapotranspiration.

These efficient precision irrigation systems are becoming cheaper and easier for farmers to use. However in tropical and sub-tropical areas, the technology can be difficult to apply smallholder farming, where there is often insufficient Internet connectivity, expertise, capital investment, and supply of energy and water. Several precision agriculture projects are working to overcome these challenges to promote efficient use of irrigation water, including in the semi-arid Pavagada region of India, the Gash Delta region of Sudan and São Paulo, Brazil. In Nepal, a Water Resources Information System has been established that collects data to inform river management, whereas in Bangladesh hundreds of solar-fuelled irrigation pumps have been installed that simultaneously reduce reliance on fossil fuels and reduce GHG emissions.

Hydroponic systems whereby plants are grown in water containing nutrients are becoming increasingly popular; the global market for hydroponics is projected to reach £325 million by 2020. Compared with land-based agriculture, hydroponics uses less land; causes less pollution and soil erosion and so these systems are less vulnerable to climate change. Critically they also reduce water use; once the initial water requirements are met, the closed-system recycles water and there is less evapotranspiration. The adoption of these systems is predicted to occur predominately in water stressed regions of the Middle East and Africa and in highly urbanised countries such as Israel, Japan and the Netherlands.

How can researching traditional approaches help?

It’s not just about agri-tech; there are relatively simple, traditional ways to tackle water issues in agriculture. To protect against drought, farmers can harvest and store rainwater during heavy downpours by building ponds and storage reservoirs. To reduce water wastage, farmers can improve the ability of soil to absorb and hold water through reducing tillage and using rotational livestock grazing, compost, mulch and cover crops. Wetlands, grasslands and riparian buffers can be managed to protect against floods, prevent waterlogging of crops and improve water quality. Increasingly these traditional methods valued and research is being done to optimise them. For instance a novel forage grass hybrid has been developed that is more resilient to water stress and can reduce runoff by 43 – 51% compared with conventional grass cultivars.

How can crop and livestock breeding help?

In the past, crop and livestock varieties have been selected for high productivity. However, these varieties are often severely affected by changes in climate and extreme weather events such as drought and require high levels of water and nutrients. To improve resilience and sustainability, breeders increasingly need to also select for stress responses and resource use efficiency. In crops, drought resilience and water use efficiency is influenced by many traits, including root and shoot architecture, stomatal density and thickness of the waxy cuticle that covers leaves and reduces evapotranspiration. The complexity of these traits makes breeding crops for drought resilience challenging, as many different groups of genes need to be selected for. To deal with this, the International Rice Research Institute’s Green Super Rice project has been crossing high-yielding parent lines with hundreds of diverse varieties to produce new high-yielding varieties that require less water, fertilisers and pesticides. These varieties are now being delivered to farmers in countries across Asia and Africa. Similarly, climate change resilience is also vital for current and future livestock farming. Projects run by Professor Eileen Wall (SRUC) have identified novel traits and genes associated with drought and heat resilience in UK and African dairy cattle, which can be incorporated into breeding programmes.

What are the incentives?

Although these projects might sound promising, without incentives to drive their uptake it may take a long time for real impacts to come to fruition. Unfortunately, in some countries such as India there can be a lack of monetary incentives that would effectively enable farmers to take up new water management technology and practices. In the EU, the Common Agricultural Policy (CAP) has allocated funds to support farmers in complying with ‘greening rules’ that improve sustainability, preserve ecosystems and efficient use of natural resources, including water. Farmers across the EU receive CAP payments for environmentally friendly farming practices, such as crop diversification and maintaining permanent grassland.

In many European countries, there is increasing consumer demand for sustainably farmed food products. This is driving large and small manufacturers to seek out sustainable suppliers and so farmers are incentivised to improve the sustainability of their farming practices so that they can be certified.  For instance the Sustainable Farming Assurance Programme requires farmers to follow good agricultural and environmental protection practices, including sustainable water use. In the coming years, more food products are likely to have water foot print labels that provide the consumer with information on the amount of water used during production and processing. This places considerable power in the hands of the consumer and large manufacturers are responding. For instance, by 2020 Kellogg has pledged to buy ten priority ingredients (corn, wheat, rice, potatoes, sugar and cocoa) only from farms that prioritise protecting water supplies, as well as using fertilizers safely, reducing emissions, and improving soil health. And Pepsico has created sustainable agriculture sourcing programmes that aim to help farmers improve water and soil resource management, protect water supplies, minimise emissions and improve soil health.

What can we do?

There are ways to take responsibility for reducing our own water footprints, including reducing meat and animal production consumption, reducing food wastage and buying sustainably farmed products. Finally, we can all get involved with communicating and promoting the importance of water in agriculture so that more people are aware of the issues. Head to the World Water Day website to find out about resources and events that may be happening near you.

On the lively materiality of soil: A Somali Drylands artistic collaboration

Posted on by janet.crompton
© Sage Brice, 2018.

The WIDER-SOMA project was a cross-disciplinary and multi-institution research collaborative project headed by Dr Katerina Michaelides at the University of Bristol, investigating the effect of warfare on dryland environments in Somalia. I was excited to be invited to join the project in its later stages as artist in residence, supported by a small grant from the Cabot Innovation Fund. As an artist-geographer, my work explores the potential of drawing as a research methodology. I am interested in the unexpected things that happen in cross-disciplinary encounters, and the hazy zones where categories and definitions begin to break down.

The brief was to produce an artwork responding to the range of research specialisms involved in the project, to celebrate the ‘liveliness’ both of the collaborative research processes, and of the Somali Drylands themselves. We wanted to push back against the idea of drylands as ‘dead spaces’, drawing on the knowledge of people who engage closely with these landscapes in different ways, and appreciate their rich and complex ecologies.

I took as my starting point the lively materiality of the soil itself – its vibrant colours, varied textures, and characteristic dispositions offered a tangible way of engaging with the remarkable diversity within the research site. I was prompted by a comment from Dr Marianna Dudley, head of Bristol’s Centre for Environmental Humanities, and a key contributor to the project:

I love the way the soil gets loose and wanders. When we had the exhibitions in London and Bristol we found that the soil got everywhere; even though it was displayed in petri dishes, and when it hadn’t been moved – still the soil got out.

The messy, wandering, sideways processes were what interested me: how did ideas and inspiration cross between researchers in different disciplines, or between researchers and the materials they encountered? Could I, as an artist, enrich, facilitate, or make tangible those processes?

I decided to create two large drawings with the earth pigments, using layers of imagery relating to the different strands of research, and letting them overlap and disrupt each other on the surface of the paper. I was interested in everything – in my e-mail to participants I asked for

photographic imagery of microbial life, soil colour-charts, scribbles and sketches from the margins of your notebooks, graphs and maps, snapshots, postcards from sites you visited, random finds, slide presentations, logos and letterheads, gifts and mementos – anything and everything.

Thus I set out in a quest for incidental imagery – seeking out the visual traces of process, and looking to see where they might differ from the formalised imagery of presentations.

© Sage Brice, 2018.

I met and interviewed many of the researchers involved in the project, to hear about their specific strand of the research, and what about it had been most animating – but also to explain more clearly what I was after. To scientists used to presenting only clean, clear, and coherent findings, it seemed counterintuitive to ask for scribbles, notes, sketches, and first attempts. Many of the processes were more fully digitised or highly sanitised than I had imagined – in some cases there was little to work with visually, and I instead sourced imagery from internet searches, based on keywords the researchers helped to define.

© Sage Brice, 2018.

Once I had collected what I needed, I set about sifting through the material, sampling and experimenting with the soils themselves as pigments, feeling my way into an encounter with the various strands of material and practice. Working with the soils was a joy – as pigments they produced a richly clouded medium, with a range of textures and tones. I worked vertically with a water-based medium, allowing the pigments to dribble and disturb each other. Some were sandy or gritty and difficult to work – others sleek, fluid, and vibrant. I used each soil to draw imagery relating to its source of origin, and layered them over each other by colour to differentiate the strands of the work.

© Sage Brice, 2018.

The two drawings are arranged to echo and contrast with one another – a digitally plotted map against a hand-drawn one; the frenetic lines of cyanobacteria and a delicate web of roads, the sharp line of a mounted machine gun and a goat’s left horn. The drawings are large; seen close up the textures of the soils are on an equal standing with the content of the imagery.

The different threads of the project come together here in a messy collision – sometimes speaking to each other, sometimes disturbing each other. As a practice-based researcher with a special interest in cross-disciplinary collaboration, I am interested in how art processes can help to draw unexpected connections and enliven relations across conventional disciplinary divides. Coming in towards the end of a project, my role here was to look back at what had been done, to draw out and enliven an account of the collaborative process. I believe this way of working is important, and has a lot to offer for building connection, right from the start. Teasing out resonances between different disciplines of practice can help encourage people to work together and to step outside their comfort zones, in order to think afresh with new tools and approaches. I learned a lot about diverse kinds of research from interviewing the different participants – but what they consistently valued most from the process was what they learned from encountering and learning to understand each other’s work.

Collecting silences

Posted on by janet.crompton

‘Noise’ is the Greenhouse gas (GHG) emissions which have resulted from fossil-fuel-powered economic growth which is measured as GDP for particular territories. In Figure 1, ‘noise’ is the area below the green line to the left of the vertical dotted line (historical) and below the blue line to the right of the vertical dotted line (projected). ‘Silence’ is the reduction of fossil-fuel use and the mitigation of carbon emissions. In Figure 1, ‘silence’ is the green shaded area above the blue line and below the dotted blue line to the right of the vertical dotted line.

Figure 1

To ensure that we maintain atmospheric GHG emission concentrations conducive to human habitation and the ecosystems that support us, we need to assign less value to ‘noise’ (burning fossil fuels) and more value to ‘silence’ (GHG emission mitigations). Creating a system which assigns value to ‘silences’ by turning them into investable resources requires an effort sharing mechanism to establish demand and organizational capacity alongside accurate measuring, reporting and verification for supply.

Organizational capacity for supplying ‘silences’ depends on the ability of organizations to create, trade and accumulate GHG emission mitigations. Due to the intangible nature of such ‘silences’, turning GHG emissions mitigations into investable sources requires their assetization as quasi-private goods with well-defined and delineated quasi-property rights. As preservations of the intangible commodity of stable atmospheric GHG concentrations through the reduction of pollution, such rights need to protect investment by ensuring that these private goods are definable, identifiable and capable of assumption by third parties. Such rights also require enforcement and protection against political and regulatory risk.

Commodifying GHG emission mitigations as quasi-private goods by assetizing them with well-defined and delineated quasi-property rights therefore provides the basis for the supply of ‘silences’. Rather than ‘internalising’ the cost of stabilising or reducing atmospheric GHG concentrations, this approach assigns value to GHG emission mitigations. Yet, if we want to avoid climate catastrophe according to the most recent IPCC 1.5C report and the UNDP Emissions Gap Report, GHG emission mitigations also require concretization on the demand-side. There are several examples of GHG emission mitigation and energy demand reduction assetization that can help illustrate how such systems of demand and supply can function.

Similar to GHG emission mitigations, energy demand reductions also represent the reduction of an intangible commodity vis-à-vis a baseline. While stable atmospheric GHG emission levels are the intangible commodity in the case of the former, in the case of the latter the intangible commodity is energy supply which fuels economic growth. Both require the assetization of mitgations/reduction to create ‘tangibility’, which provides the basis for assigning value. To illustrate, energy demand reductions are absent on domestic and corporate accounts and subsequently undervalued vis-à-vis increases in revenues.

Market-based instruments that succeed in setting and enforcing targets and creating systems of demand, however, can create ‘tangibility’. Energy demand reductions, for example, are assetized as white certificates representing equal units of energy savings (negawatts) in white certificate markets. Similarly, demand-side response enables the assetization of short-term shifts in energy (non-)use (flexiwatts) to benefit from flexibility and balancing markets. Carbon emission mitigations are assetized under the Clean Development Mechanism (CDM) as Certified Emissions Reductions (CERs).

Crucially, these examples shift the emphasis from the cost of pollution and the need to ‘internalise’ this cost or from turning pollution into a quasi-private good through Emissions Trading Schemes (ETS) towards the positive pricing of energy demand reductions and carbon emission mitigations. Positive pricing turns their respective reduction and mitigation itself into a quasi-private good by turning ‘silences’ into investable resources.

The main technical difficulty of establishing such systems lies in the definition of baselines and measuring, reporting and verification vis-à-vis these baselines. The difficulties inherent in this approach are well documented but improved sensing technology, such as the Internet of Things (IoT), and distributed ledgers promise greatly improved granularity and automated time-stamping of all aspects of energy (non-)use at sub-second intervals. If structures of demand are clearly identified through target-driven market-based instruments and supply is facilitated through the assetization of ‘silences’ as quasi-private goods with clearly defined and enforced quasi-property rights, a clear incentive also exists to ensure that MRV structures are improved accordingly.

Key to the implementation of such target-driven market-based instruments are mechanisms to ensure that efforts are shared among organisations, sectors or countries, depending on the scale of implementation. Arguably, one of the reasons why the CDM failed in many aspects was because of the difficulty of proving additionality. This concept was supposed to ensure that only projects that could prove their viability based on the availability of funds derived from the supply, trade and accumulation of CERs would be eligible for CDM registration.

The difficulty of proving additionally increases cost and complexity. To ensure that new mechanisms no longer require this distinction, a dynamic attribution of efforts is required. A mechanism to dynamically share efforts can also help address rebound effects inherent in energy efficiency and energy demand reduction efforts. Key is the target-driven nature of associated market-based instruments and the equitable distribution of the rebound through a dynamic mechanism which shares any rebounds (i.e. increases in carbon emissions) equitably among organisations, sectors or countries. With an appropriate effort-sharing mechanism in place, the demand and supply of ‘silences’ can be aligned with targets aiming to maintain atmospheric GHG emission concentrations in line with levels conducive to human habitation and the ecosystems that support us.

Downhill all the way: Monitoring landslides using geophysics

Posted on by janet.crompton

Developments in geophysical methods used to monitor surface and subsurface changes prior to landslides can lead to improved prediction and early warning.

Every year, landslides cause fatalities and destruction in locations worldwide. Nevertheless, what triggers them and when they occur can often be difficult to predict. A recent article in Reviews of Geophysics examined developments in landslide monitoring using insights and methods from geophysics. Here, one of the authors of the paper answers some questions about landslide monitoring and prediction.

Why is the monitoring of landslides important, and what role can geophysics play?

Sometimes the most effective option for mitigating the risk from landslides is monitoring.

In an ideal world, we would have the geotechnical and financial resources to be able to remove all landslide hazards through slope stabilization and remediation. In reality, this just isn’t possible, and sometimes the most effective option for mitigating the risk from a landslide is to monitor it.

Historically, this has been done by monitoring deformation at the surface and by looking at changes from localised points in the subsurface; for example, by measuring fluctuations in the water table in a borehole. Variations in these data may provide clues about when slope failure is imminent.
The advantage of geophysical methods is that they can not only monitor subsurface properties and how they change over time but can also do so at much higher spatial resolution and over a wider area than point sources of information, such as boreholes.

What are the different types of landslides and why are geophysical methods particularly useful for monitoring “moisture-induced” landslides?

“Landslide” is one of those words that sounds simple enough to define but in reality is very complex.

One of the distinctions we can make between landslide types is their triggering mechanism; most landslides are caused by the direct consequences of increased rainfall and shaking by earthquakes, but they can also be a result of secondary factors such as deforestation.


Between 2007 and 2016, 83% of landslides globally were triggered by rainfall or other hydrological events. This is why we use the term “moisture-induced” in our review article, as it reflects the complicated nature of all sources of water present in landslide systems, including rainfall, snow-melt, and groundwater, amongst others.

Introducing increased amounts of water into a landslide changes the properties of the subsurface, which leads to destabilization and, when a critical threshold is exceeded, slope failure. These changes in material properties can be monitored by geophysical methods and, by comparing data collected over time, it is possible to make inferences about the destabilizing processes that are occurring in the subsurface of the landslide system.

What different geophysical methods are used to gather information about moisture-induced landslides?

The majority of studies used passive seismic and active geoelectrical methods.

Our review article looks at published case studies from the past 12 years to see what kinds of methods are being applied to monitor moisture-induced landslides. What struck us was that the majority of studies used one of two methods: passive seismic and active geoelectrical methods.


Passive seismic monitoring has been used for many decades in global seismological studies, but really only started to be scaled down to look at smaller scale features, such as landslides, in the mid-1990s.

Although passive seismic monitoring has been around longer, monitoring landslides using active geoelectrical methods, primarily electrical resistivity (ER), has really taken off in the last decade or so. There have been several studies in which ER technologies have been developed specifically for landslide monitoring approaches. Consequently, ER monitoring is currently able to provide more information than passive seismic monitoring on the pre-failure conditions of landslides.
Lower equipment costs and power consumption, combined with better data management and equipment durability, means we can collect more geophysical data for longer from landslides. Each of the points in this plot shows information gathered from published case studies about the length of time and amount of data acquired during a single geophysical monitoring campaign. Multiannual campaigns are becoming increasingly common compared to nearly a decade ago. Credit: Whiteley et al. [2018], Figure 6

 

What do these methods tell us about the subsurface conditions of landslides?

The two approaches provide an opportunity to better understand the variable nature of the subsurface in time and space.

Passive seismic and active geoelectrical approaches complement each other very well. First, they tell us about different aspects of the subsurface conditions beneath a landslide. Seismic methods are able to tell us about the strength of the ground, while ER methods provide information about subsurface moisture dynamics. Both of these aspects are very important when trying to predict landslide movements.


Second, passive approaches tend to have great temporal resolution, but their spatial coverage can be limited by the number of seismic sensors deployed on a slope, usually due to cost or power requirements. On the other hand, ER methods can provide very high spatial resolution, but as they are dependent on collecting a set of data from many measurements, their temporal resolution can be limited. Together, the two approaches provide an opportunity to better understand the variable nature of the subsurface in time and space.

What advances in equipment and data analysis have improved understanding of landslide processes?

The financial, computational, and energy cost of equipment is continually reducing, which means we can collect more data for longer periods, and send data from the field to the lab for near real-time analysis.

Also, data telemetry means we can send data from the field to the lab for near real-time analysis. Both of these are crucial when using geophysical methods for early-warning of landslide failure.

Recently, there has been an increase in the use of 3D surveys and petrophysical relationships linking geophysical The financial, computational and energy cost of equipment is continually reducing, which means we can collect more data for longer periods. Also, data telemetry means we can send data from the field to the lab for near real-time analysis. Both of these are crucial when using geophysical methods for early-warning of landslide failure.

In ER monitoring, movements in the electrode array would have historically produced errors in the resistivity model, but developments in ER data inversion can now use this source of “error” to track movements in the landslide. Similarly seismic “ambient noise” is being used in innovative ways to monitor landslides, even though these background signals would have traditionally been undesirable in seismological surveys.

Where is the field of geophysical monitoring of moisture-induced landslide heading?

The challenge now is to start looking for clues to identify precursory conditions to slope failure and to develop geophysical thresholds to inform early-warning approaches. 

The great news is that this is a very active area of research! There is a lot of work being done in environmental seismology to increase the number of low-cost, low-power seismic sensors that can be deployed in landslide settings. This is important, as it will allow us to monitor landslides at very high-resolution in both the spatial and temporal domain.

Looking to the future, one can envision “smart sensor” sites that provide power, data storage, and telemetry, accommodating a wide range of integrated geophysical, geotechnical, and environmental monitoring methods. These could include seismic and electrical arrays, wireless sensor networks, and weather stations, with data relayed back to central processing sites for near-real time assessment, and early-warnings of impending failure based on calibrated geophysical thresholds.

Mothering Earth: Raising kids in uncertain times

Posted on by janet.crompton

Did you know women are more likely than men to be affected by climate change? UN figures indicate that 80% of people displaced by climate change are women. And in light of the recent strikes by children across the world, it is clear that it is the most pressing issue for a lot of children around the world. So then, what role do mothers play in guiding and supporting our children in a changing climate? And what is it like to know the dangers of climate change and bring up a child in an uncertain world?

The guilt

You only have to visit forums like Mumsnet to see that climate change is being discussed quite frequently and with anxiety (for those who care) around how it will affect their children’s futures. As highlighted on the Victoria Derbyshire programme, young women across the world are contemplating whether to have kids at all for fear of how climate change will degrade their children’s lives. In fact a new group called BirthStrike has risen up in the belief that it would be unjust to raise children in an increasingly damaged world. Even Alexandria Ocasio-Cortez, an increasingly popular American politician and activist said in an Instagram livestream “Our planet is going to hit disaster if we don’t turn this ship around … there’s scientific consensus that the lives of children are going to be very difficult”. So for women today, if you do decide to have children or already have them in this warming world, you do have these feelings of guilt, as well as anxiety and despair for their futures.

When you are a mum working in the environmental sector, it’s really quite tough balancing being a good mum and doing your bit for the planet, even with the best intentions! Whether we like it or not, kids and babies are incredibly wasteful. Whether it is growing quickly out of their clothes that they’ve only worn for the last three months or wasting food by throwing it around or not eating their meals because they are fussy, all the things they break that have to be thrown away and replaced and even all the washing you have to do, so much water and energy is used on a weekly basis. And don’t even get me started on all the plastic tat, balloons and wasteful gifts produced for children’s birthdays…

As someone who decided to have a child a couple years ago knowing full well what was happening to the planet because I work for the Cabot Institute for the Environment, it really was a tough decision for me. But I was technically going to be a ‘geriatric mother’ by the time I gave birth and so I decided that I would have a kid before it was too late biologically. I justified it to myself by deciding to buy second hand toys and baby clothes where possible (luckily I’ve had lots of hand me downs!); cut back drastically on consuming animal products; I have a 100% renewable energy tariff and I haven’t flown for three years besides many other things I’m trying my hardest at doing for the sake of the planet.  I also decided that I would raise my kid as best as I could to know what nature was, to respect it, cherish it and protect it and my hope is that he will contribute something positive to the planet as he grows up. Yet still there is that guilt and feelings of hypocrisy that what I am doing is not enough.

How do academic mums feel?

Working at the University of Bristol are many mothers who study the effects of climate change on the atmosphere, land and oceans and on living things such as animals, plants and humans. There are mothers who look at risk, uncertainty and climate related disasters and there are engineers who are dreaming up ways to fix things. So how do these mums feel about knowing what will happen in the near future?  I asked around and here are some responses from my colleagues:

Professor Dani Schmidt

Professor Dani Schmidt

Dani studies the biotic response to climate change, focusing on ocean acidification and its impacts on marine ecosystems. She is a Wolfson Merit Scholar with the Royal Society and sits on the Intergovernmental Panel for Climate Change Working Group II, Chapter 6 Ocean Systems, AR5. Dani said:

“I think it is important to remember that our children will have the power to change the world. It is in our power to change what the world will look like in which our children will grow; the world they will look after. We need to raise thinkers, scientists, engineers who think differently. The worst we could do for our children is to give up hope and not empower them to come up with ideas. Despair hinders action. There is so much to do, new transportation, new energy efficiency, learning to take the CO2 out of the atmosphere again to name just a few. We need to inspire our children to love nature, as we will protect what we treasure”.

Dr Frances Cooper

Dr Frances Cooper

Frances’ research is focused on understanding the mechanics of large-scale continental deformation and the evolution of orogenic systems. In plain English, her work looks at natural hazards and risk. Frances said:

“My son is nearly 18 months old, which means he will be my age in 2056. If global warming continues at its current rate, it will have breached the 1.5°C recommended by the IPCC by this time, resulting in more severe weather patterns, destruction of ecosystems, and melting of the ice caps. It is, of course, impossible not to dwell on this when I think about his future, but I think it’s important to respond with affirmative action. Although he is too young at the moment to understand climate change, it will be an important part of his education and I want to raise him as someone who is engaged with the issue and proactive about doing something to prevent it. Nurturing his curiosity in nature and the outdoors will be an early stepping stone, getting him excited and interested in the world around him. This way, I hope that he will grow up with an appreciation of how his actions impact the environment and that he has a responsibility to protect it.”

Dr Katharine Baldock

Katherine is a community ecologist whose research focuses on insect pollinators and how processes such as urbanisation affect pollinator communities. She is a NERC Knowledge Exchange Fellow based in the School of Biological Sciences. Kath said:

“The effects of climate change on animals, plants and processes that maintain the earth’s ecosystems are becoming ever more concerning. Unseasonable temperatures and unpredictable weather can impact on natural biological processes. The timing of events such as leaf emergence, insect emergence and flowering can be altered and become uncoupled from species which depend on them, for example flowers may be in bloom before their pollinators have emerged in the spring.

“What effects will these changes have on the natural world that my son grows up to experience? Will polar bears still have a habitat in the wild or will they be confined to only to zoos? Exposing our children to nature from an early age will benefit not only their health and wellbeing but hopefully embed in them a sense of wonder of the natural world and a desire to preserve and protect it. And they need first-hand experience, not just through the wonderful wildlife documentaries on our screens. I have recently started taking my 18 month old son to forest school, a first step on his journey with nature. He is already fascinated by birds and other animals and I hope this will grow into an appreciation for the environment and an understanding of how important his and others’ actions will be to the future of our planet.”

A motherly uprising?

It’s not all doom and gloom and anxiety and guilt though. There are some fantastic female led groups who are rising up to take on the climate change challenge, like 1 Million Women, who are building a global movement of women and empowering them to change their lifestyles. By doing this the many mothers who make up this group are also empowering and changing the lifestyles of their friends and families too. It’s win win. There is a new group of mums called Mothers Rise Up who are sick of feeling helpless about their children’s futures in the face of catastrophic climate breakdown and have announced “We are organising!“. Then there is Mothers Against Climate Change  who say “Women also make ~ 85% of the purchasing decisions and tend to be more empathetic and willing to share what they have learned”. Also Mothers Out Front who are “mobilising for a liveable climate”. Even former Irish President Mary Robinson and comedian Maeve Higgins have created Mothers of Invention – an uplifting new podcast celebrating amazing women doing remarkable things in pursuit of climate justice. Mothers really can, are and will make a huge difference to the way the world will tackle climate change.

Mothers as educators

If you are privileged enough to have access to educational resources on climate change, whether that be books, apps, websites, TV programmes and documentaries, do use them and share them with your child and others. If you don’t have access, visit your local library and ask to borrow some free resources.

If your child has completed a degree but wants to go on to a Masters programme, you could direct them towards the Cabot Institute’s brand new Masters by Research in Global Environmental Challenges. This is a unique one-year research project, supported by an expert supervisor, with access to a bespoke training schedule designed to enhance your child’s career prospects and help them not only to develop an interdisciplinary approach to the most complex environmental challenges of today but also to support them in becoming future leaders in environmental challenges.

The University of Bristol also offers free open online courses as part of Bristol Futures. It helps participants to investigate some of the major opportunities and challenges facing our generation: including Innovation & Enterprise; Global Citizenship and Sustainable Futures. Here at Cabot we’ve also recently partnered with actor Jeff Bridges on his new educational programme aimed at educating school and university students, focusing on issues featured in his recent award winning documentary Living in the Futures Past. Watch Cabot’s contribution to that programme, a short film on emergence  by Tom O’Shea.

And more locally, Bristol mum Traci Lewis set up Catalyse Change CIC, a social enterprise supporting girls and young women to develop sustainability skills and knowledge for ‘healthy, happy and green’ communities, careers and planet. This is a great initiative because ultimately these will be the mother’s of the future and they will continue to share their knowledge as they become mothers and grandmothers and influencers in their careers.

Mothers as communicators

A lot of women like to talk and the best thing you can do is to talk and talk some more with the people around you about climate change.  I’ve made a point to talk lots with my hairdresser about climate change issues, mainly to inform her in the hope that she will talk to her hundreds of customers about the issues too but also that she will think about her own actions.

It is also important that we talk to our children and encourage them to communicate about climate change. Climate communications organisation, Climate Outreach, has shown that young people can be  just as effective crafting a message as they are delivering it. In her recent blog for Climate Outreach, Emilie Holland Baliozian said “Inviting youth into the climate conversation is more than just giving them a voice. It means giving them a seat at the table and listening to what they have to say. Youth-led organizations all around the world, such as Zero Hour, Climates, Youth Climate Leaders, or Young Friends of the Earth, as well as the many youth plaintiffs suing their governments, are stepping up where adults are not. Let’s start listening”. Do visit the Climate Outreach website as they have lots of useful tips for communicating climate change to lots of different groups of people.

Parents are not just carers, cooks, role models, cleaners, nurses and counsellors etc they are also educators. It’s important for mums (and dads) to be supportive of their kids in the quest for knowledge and like Dani said, to ‘inspire’ our children and that can be done by leading by example, so may be consider putting yourself on the Bristol Futures courses or attending a climate strike. Greta Thunberg is organising another international school strike on 15 March 2019. As mothers we could encourage our children to attend, we could also go with them and show our support, even better we could rally up our friends, colleagues and family members to join in too.

I, like my colleagues, am incredibly privileged to have up to date access to the latest research on climate change. If you want to be kept informed too, do sign up to the Cabot Institute newsletter.  I am not only a mother but an educator and I will do all that I can to pass on my knowledge to my child and inspire him in the wonder of nature, that we as humans often forget or don’t realise we are intrinsically part of, so that his generation may just have a brighter future by learning to ‘mother’ their Earth.
