A successful haiku could be described as a half-finished poem. Originating in Japan in the 17th century, the haiku uses a combination of sensory language, seasonal references, a sense of contrast and a focus on the present tense to share an experience between writer and reader.
It relies on the reader to “finish” the poem by employing their recollections of sensations and emotions to connect to the moment described as vividly as they do their own experiences.
Haiku often depict moments in a particular season by describing the behaviour of animals, the weather and the appearance of plants. With a new generation of haiku poets, there’s a whole new collection of work that reflects how seasons are changing as a result of rising global temperatures.
Could haiku poetry written more recently contain a trace of the changes wrought by our warming climate? That’s something one of us (Jasmin) set out to investigate by analysing haiku published in English over the last 30 years.
First, let’s learn how to read haiku.
Do the seasons feel increasingly weird to you? You’re not alone. Climate change is distorting nature’s calendar, causing plants to flower early and animals to emerge at the wrong time.
This article is part of a series, Wild Seasons, on how the seasons are changing – and what they may eventually look like.
What enables this brief poetic form to achieve its resonance is its use of negative space. A haiku is a poem in two parts – a fragment (one line) and a phrase (two lines), divided by a pause (signified by a line break or punctuation).
Related to the concept of ma in Japanese visual arts, which perceives empty space in an artwork as a positive entity, the negative space in haiku is a way in to the contemplative experience of the poem.
The following by Japanese poet Matsuo Basho (1644-94) is the most famous haiku ever composed:
To write a different account of this same event, you could say something like a frog leapt into an old pond and made a sound. But the key distinction between the two is the negative space that follows Basho’s first line. It encourages the reader to pause, breathe and contemplate the old pond before they encounter the frog leaping and the sound of the water.
When our minds become still, and reflective, like the old pond, we witness the action of an animal living simply according to its nature. We perceive things just as they are. The result is an experience of interconnectedness: a realisation that we are not separate from the natural world, but a part of it.
In the following haiku by Basho we experience the season as both a physical setting and as a metaphor for emotional experience:

In a world of increasing anxiety and distraction, the negative space in a haiku affords us moments of reflection and invites us into a dialogue with the rest of the natural world.
It requires a sensitivity on the part of the reader, but its effect is to instil an appreciation for what surrounds us. Through a meaningful, felt awareness of the seasonal cycles, the reading and writing of haiku inspires a deeper connection to our environment.
How haiku is changing
I spent the summer of 2022 in my home office, consuming decades of haiku journals and anthologies, trying not to leave sweaty fingerprints on their ancient covers in the unnatural 40°C heat. As that year’s researcher-in-residence for the British Haiku Society, working on a project called Twisting Point, I was searching for tell-tale traces of climate change in the English-language haiku archives.
My goal was to contrast present-day haiku against older archival ones, using the differences between them to make readers sensitive to nature’s decline and to suggest how the English-language haiku form might be evolving due to climate change.
I was looking at 30 years’ worth of haiku. In the UK during this time flying insect populations have fallen by over 60%, 41% of wildlife species have decreased in abundance and the frequency of heatwaves, floods and other extreme weather have all increased. More than enough change has occurred in these three decades to manifest in the archives.
Yet, these changes emerge in a strange fashion. It’s hard to write about nature’s losses, and writers tend to do so unconsciously. Rather than tracking population declines in concrete terms, then, the language used around certain species has altered, becoming soaked in grief.
For example, over 25 years numbers of curlews, a wading bird, have halved in the UK. Earlier haiku described their powerful cry “lengthen[ing] the hill[s]”; a poem written in 2022 found them “calling across wintry mudflats, haunting the wind”. Similarly, since 2000, declining butterflies have moved from being a “cloud” common in the background of haiku to lone survivors “pushing against time”.

The archetypal seasonal words used in haiku are shifting too, disrupting centuries-long traditions of meaning and emotion. As winter has been squeezed into weeks, spring arrives earlier and frosts become tardier, snowdrops have become a symptom of the changing haiku form.
Here is a haiku published in the 1990s in the spring seasonal category (the traditional haiku date for spring’s beginning is February 4):
song of a greenfinch
a ray of sun on cold steps
and a few snowdrops
By 2022, snowdrops are emerging in December in this tanka (a slightly longer poem variety) by Ruth Parker:
I was struck by how few haiku seemed to address climate change. Twisting Point became my call to arms for haiku writers. Haiku are about intense moments of perception, in which “the vast is perceived in one thing”. But in addressing climate change so little, are English-language haiku really depicting “the vast”?
Since 2022 the issue has come to the fore, with The Guardian describing how Japanese haiku writers are “lost for words” in the face of climate change. Meanwhile, Twisting Point is to be republished in a journal of the New Zealand Poetry Society. The call to haiku arms is growing: the vast climate crisis is upon us, and we should write about it.
East Africa has recently had an unprecedented series of failed rains. But some rainy seasons are bringing the opposite: huge amounts of rainfall.
In the last few months of 2023, the rainy season known as the “short rains” was much wetter than normal. It brought severe flooding to Kenya, Somalia and Tanzania. In Somalia, more than 2 million people were affected, with over 100 killed and 750,000 displaced from their homes. Tens of thousands of people in northern Kenya lost livestock, farmland and homes.
The very wet short rainy seasons are linked to a climate event known as a positive Indian Ocean Dipole (known as the “IOD”). And climate model projections show an increasing trend of extreme Indian Ocean dipoles.
In a new research paper, we set out to investigate what effect more frequent extreme Indian Ocean Dipole events would have on rainfall in east Africa. We did this using a large number of climate simulations and models.
Our results show that they increase the likelihood of very wet days – therefore making very wet seasons.
We recommend that decision-makers plan for this kind of extreme rainfall, and the resulting devastating floods.
How the Indian Ocean Dipole works
Indian Ocean Dipole events tend to occur in the second half of the year, and can last for months. They have two phases: positive and negative.
Positive events occur when the temperature of the sea surface in the western Indian Ocean is warmer than normal and the temperature in the eastern Indian Ocean is cooler than normal. Put simply, this temperature difference happens when winds move warmer water away from the ocean surface in the eastern region, allowing cooler water to rise.
In the warmer western Indian Ocean, more heated air will rise, along with water vapour. This forms clouds, bringing rain. Meanwhile, the eastern part of the Indian Ocean will be cooler and drier. This is why flooding in east Africa can happen at the same time as bushfires in Australia.
The opposite is true for negative dipole events: drier in the western Indian Ocean and wetter in the east.
Under climate change we’re expecting to see more frequent and more extreme positive dipole events – bigger differences between east and west. This is shown by climate model projections. They are believed to be driven by different paces of warming across the tropical Indian Ocean – with western and northern regions projected to warm faster than eastern parts.
Often heavy rain seasons in east Africa are attributed to El Niño, but recent research has shown that the direct impact of El Niño on east African rainfall is actually relatively modest. El Niño’s principal influence lies in its capacity to bring about positive dipole events. This occurs since El Niño events tend to cool the water in the western Pacific Ocean – around Indonesia – which also helps to cool down the water in the eastern Indian Ocean. These cooler temperatures then help kick-start a positive Indian Ocean Dipole.
Examining unprecedented events
Extreme positive Indian Ocean Dipole events are rare in the recent climate record. So to examine their potential impacts on rainfall extremes, we used a large set of climate simulations. The data allowed us to diagnose the sensitivity of rainfall to larger Indian Ocean Dipole events in a statistically robust way.
Our results show that as positive dipole events become more extreme, more wet days during the short rains season can be expected. This effect was found to be largest for the frequency of extremely wet days. Additionally, we found that as the dipole strength increases, the influence on the most extreme days becomes even larger. This means that dipole events which are even slightly “record-breaking” could lead to unprecedented levels of seasonal rainfall.
Ultimately, if positive Indian Ocean Dipole seasons increase in frequency, as predicted, regular seasons of flooding impacts will become a new normal.
One aspect not included in our analysis is the influence of a warmer atmosphere on rainfall extremes. A warmer atmosphere holds more moisture, allowing for the development of more intense rain storms. This effect could combine with the influence of extreme positive dipoles to bring unprecedented levels of rainfall to the Horn of Africa.
In the long term it is crucial to ensure that any new infrastructure is robust to withstand more frequent and heavier rains, and that government, development and humanitarian actors have the capacity to respond to the challenges.
These technological improvements are crucial. But better use of the forecast information we already have can also make a big difference. For instance, initiatives like “forecast-based financing”, pioneered by the Red Cross Red Crescent movement, link forecast triggers to pre-approved financing and predefined action plans, helping communities protect themselves before hazards have even started.
For these endeavours to succeed, there must be dialogue between the science and practitioner communities. The scientific community can work with practitioners to integrate key insights into decisions, while practitioners can help to ensure research efforts target critical needs. With this, we can effectively build resilience to natural hazards and resist the increasing risks of our changing climate.
Frank Herbert’s Dune is epic sci-fi storytelling with an environmental message at its heart. The novels and movies are set on the desert planet of Arrakis, which various characters dream of transforming into a greener world – much like some envision for Mars today.
We investigated Arrakis using a climate model, a computer program similar to those used to give weather forecasts. We found the world that Herbert had created, well before climate models even existed, was remarkably accurate – and would be habitable, if not hospitable.
However, Arrakis wasn’t always a desert. In Dune lore, 91% of the planet was once covered by oceans, until some ancient catastrophe led to its desertification. What water remained was further removed by sand trout, an invasive species brought to Arrakis. These proliferated and carried liquid into cavities deep underground, leading to the planet becoming more and more arid.
To see what a large ocean would mean for the planet’s climate and habitability, we have now used the same climate model – putting in an ocean while changing no other factors.
When most of Arrakis is flooded, we calculate that the global average temperature would be reduced by 4°C. This is mostly because oceans add moisture to the atmosphere, which leads to more snow and certain types of cloud, both of which reflect the sun’s energy back into space. But it’s also because oceans on Earth and (we assume) on Arrakis emit “halogens” that cool the planet by depleting ozone, a potent greenhouse gas which Arrakis would have significantly more of than Earth.
The authors gathered information from the books and the Dune Encyclopedia to build their original model. Then they added an ocean with 1,000 metres average depth. Farnsworth et al, CC BY-SA
Unsurprisingly, the ocean world is a whopping 86 times wetter, as so much water evaporates from the oceans. This means plants can grow as water is no longer a finite resource, as it is on desert Arrakis.
A wetter world would be more stable
Oceans also reduce temperature extremes, as water heats and cools more slowly than land. (This is one reason Britain, surrounded by oceans, has relatively mild winters and summers, while places far inland tend to be hotter in summer and very cold in winter). The climate of an ocean planet is therefore more stable than a desert world.
In desert Arrakis, temperatures would reach 70°C or more, while in its ocean state, we put the highest recorded temperatures at about 45°C. That means the ocean Arrakis would be liveable even in summer. Forests and arable crops could grow outside of the (still cold and snowy) poles.
There is one downside, however. Tropical regions would be buffeted by large cyclones since the huge, warm oceans would contain lots of the energy and moisture required to drive hurricanes.
The search for habitable planets
All this isn’t an entirely abstract exercise, as scientists searching for habitable “exoplanets” in distant galaxies are looking for these sorts of things too. At the moment, we can only detect such planets using huge telescopes in space to search for those that are similar to Earth in size, temperature, available energy, ability to host water, and other factors.
Both desert and ocean Arrakis are considerably more habitable than any other planet we have discovered. Farnsworth et al, CC BY-SA
We know that desert worlds are probably more common than Earth-like planets in the universe. Planets with potentially life-sustaining oceans will usually be found in the so-called “Goldilocks zone”: far enough from the Sun to avoid being too hot (so further away than boiling hot Venus), but close enough to avoid everything being frozen (so nearer than Jupiter’s icy moon Ganymede).
Research has found this habitable zone is particularly small for planets with large oceans. Their water is at risk of either completely freezing, therefore making the planet even colder, or of evaporating as part of a runaway greenhouse effect in which a layer of water vapour prevents heat from escaping and the planet gets hotter and hotter.
The habitable zone is therefore much larger for desert planets, since at the outer edge they will have less snow and ice cover and will absorb more of their sun’s heat, while at the inner edge there is less water vapour and so less risk of a runaway greenhouse effect.
It’s also important to note that, though distance from their local star can give a general average temperature for a planet, such an average can be misleading. For instance, both desert and ocean Arrakis have a habitable average temperature, but the day-to-day temperature extremes on the ocean planet are much more hospitable.
Currently, even the most powerful telescopes cannot sense temperatures at this detail. They also cannot see in detail how the continents are arranged on distant planets. This again could mean the averages are misleading. For instance, while the ocean Arrakis we modelled would be very habitable, most of the land is in the polar regions which are under snow year-round – so the actual amount of inhabitable land is much less.
Such considerations could be important in our own far-future, when the Earth is projected to form a supercontinent centred on the equator. That continent would make the planet far too hot for mammals and other life to survive, potentially leading to mass extinction.
If the most likely liveable planets in the universe are deserts, they may well be very extreme environments that require significant technological solutions and resources to enable life – desert worlds will probably not have an oxygen-rich atmosphere, for instance.
But that won’t stop humans from trying. For instance, Elon Musk and SpaceX have grand ambitions to create a colony on our closest desert world, Mars. But the many challenges they will face only emphasises how important our own Earth is as the cradle of civilisation – especially as ocean-rich worlds may not be as plentiful as we’d hope. If humans eventually colonise other worlds, they’re likely to have to deal with many of the same problems as the characters in Dune.
Bringing a diversity of people to the table and giving plenty of opportunities for everyone to have their say is key to ensuring real inclusivity. Rawpixel.com/Shutterstock
In early 2021, I observed a meeting of 25 people working on climate change policy in Bristol as part of my research into creating a just and fair climate transition. I was struck by how the conversation was dominated by one group: white men. From that moment, inequality in decision-making became a major part of my climate justice research.
I drew a table in my notebook with four headings: white men, white women, minoritised men and minoritised women. Every time someone spoke, I put a tick in the relevant column. By the end of that meeting, white men had three times as many ticks as the rest combined. I took a picture of the table and sent it to my research partner, Alice Venn.
“Should I keep recording this data?” I asked. Venn approved of this approach, so data on gender and race became central to our study.
We observed various meetings including steering groups, member consultations and board meetings for nine hours over the course of six months. During that time, white men spoke for 64% of the time and represented 40% of participants. A slightly higher percentage (41%) of white women were present in the meetings we observed, but they spoke for just 33% of the time.
By comparison, minoritised women made up 14% of participants in meetings and spoke 2% of the time. Minoritised men made up 5% of participants in meetings and spoke only 1% of the time.
This is no great surprise. The environment sector is notoriously one of the least diverse, with only 3.5% of people working in environmental jobs identifying as being from an ethnic minority. In the environmental charity sector, that figure is 6%. This compares quite starkly with an average across the UK workforce of 15% of employees from racial or ethnic minorities.
Diverse voices and critical discussions are key to making robust, inclusive and future-proof decisions. If a group of people who come from similar backgrounds (whether because of race, class or gender) assess a decision they are making for flaws, they are unlikely to find them because they are likely to agree with one another.
There may then be unexpected pushback against policies such as 15-minute neighbourhoods (where residents can reach all the facilities they need within a 15-minute walk, bike ride or journey on public transport), because groups who do not benefit from those schemes have not been consulted and their dissent has not been anticipated.
In Bristol, our observations of meetings found that participants showed very little critical engagement with existing policies, such as cycling route safety planning that centred around men commuting, or expansion plans for Bristol airport. Often, there was no space or time in meetings to be critical of existing ideas and narratives, or to challenge existing policy processes and systemic problems.
Climate justice was only mentioned in one of the nine meetings we observed. Climate vulnerability was not mentioned at all. Meetings felt very busy, filled with packed agendas, with little opportunity to make radical suggestions for change.
A good chair will be aware of these dynamics and take steps to ensure inclusivity, perhaps by setting up small group tasks to build confidence or monitoring who is speaking and calling on quieter people directly.
Another technique, known as the “2-2 method”, involves asking “what are two reasons someone would agree, and two someone would disagree?” before opening the floor for critique. An open workplace culture where people feel they can trust leadership even if they are critical is also important, and will make more open and inclusive meetings easier to conduct.
From observations in our study, women tend to take longer to answer a question, which gives space for men to jump in or interrupt. One of the female participants told us: “I notice men tend to talk over me and interrupt me, a lot.”
Minoritised individuals may be more reticent to speak if they feel they won’t be listened to. Previous research shows that some board members worry they will be tokenised by being asked to represent huge groups – this puts undue pressure on them to be the spokesperson for their race or ethnicity, and does not treat them as an individual with worthy opinions. Being aware of these dynamics and getting it right as an employer or community leader is key to making change and ensuring everyone feels able to speak up.
A diversity redesign
As a follow-up from our study, we are training members of the environment sector in Bristol. We have been working with the UK-wide, equalities-led social enterprise The Diversity Trust and video production company Beeston Media to provide a series of workshops and videos about making more inclusive decisions, creating an open workplace culture, and recruiting and retaining diverse staff.
So far we’ve held three workshops, each attended by more than 25 people from a wide range of sectors and organisations. Three more workshops are planned for spring and summer 2024.
As a result, the Bristol Advisory Committee on Climate Change has already changed its recruitment policies. The committee has widened its definition of an expert, moving away from a research-based definition and explicitly noting that lived experience and community knowledge can be accepted as expertise.
Meeting space policies have also been redesigned at several organisations – for example, by implementing the 2-2 method and ensuring that chairs avoid tokenism and use micro-affirmations to build confidence.
We are monitoring the impact of these changes with one-to-one support calls, surveys and peer-to-peer support groups. One testimony stated that “the training you have been running has been so valuable in helping environmental organisations to develop better equality, diversity and inclusion practice”.
Improvements to embrace a more diverse and inclusive environmental sector are critical to ensuring a greener, fairer and more sustainable future for all. But this transition needs to be designed with people, rather than imposed on them. The shift can begin in a boardroom, steering group, or committee meeting. Any institution that pays attention to how it makes decisions, and who is consulted, will help to ensure the green transition is as inclusive as possible.
When was the last time you saw a frog? Perhaps you came across one in your garden and wondered at its little hands, glossy skin and what looked very much like a contented smile.
Maybe you regularly see them on Instagram or TikTok, where “frog accounts” have proliferated in recent years. People share adorable cartoon frogs, coo over crocheted frogs or go gaga for frogs dressed in cute hats.
In fact, our fascination with frogs isn’t new. As our research has found, the history of human-frog relations is long and complicated – and not all of it is nice.
Why we love frogs
There is a rich history of people really loving frogs.
This is interesting, because many people much prefer mammals and birds over reptiles and amphibians.
But the frog is an exception – for a lot of reasons. People tend to be attracted to baby-like faces. Many species of frog have the large eyes characteristic of young animals, humans included.
Having no teeth and no sharp claws, they also do not seem to be immediately threatening, while many of them have beautiful skin colouring and some are improbably tiny.
Frogs are truly among the jewels of the natural world, unlike toads which – with their more mundane colours and “warty skins” – do not usually inspire the same sense of enchantment.
Their beauty connects us to the wider riches of a vibrant nature hidden from most people’s sight in the dense rainforests of the tropical regions.
And they also connect us to nature in our own backyards. At certain times of the year, they spontaneously appear in our gardens and ponds. They can feel like special visitors from the natural world.
Dissecting human feelings for frogs
Yet relationships between people and frogs haven’t always been so positive. In fact, frogs occupy complicated places across cultures all over the world.
In the Western tradition, the legacy of biblical and classical sources was both negative and longstanding.
References to frogs in the Bible rendered them the instrument of divine anger as a swarming plague.
Frogs challenged early modern zoological taxonomies, moving between classification as serpent, insect or reptile.
Perhaps their resistance to easy placement by humans explains the strong emotional language about them used by Swedish naturalist (and “father of modern taxonomy”) Carl Linnaeus.
These foul and loathsome animals are abhorrent because of their cold body, pale colour, cartilaginous skeleton, filthy skin, fierce aspect, calculating eye, offensive smell, harsh voice, squalid habitation, and terrible venom.
In modern science, they sit in a branch of zoology, herpetology, that brings frogs together as “creeping animals” with snakes and lizards.
Frogs have also (or perhaps consequently) suffered in the service of science since at least the eighteenth century because it seemed to be possible to easily replicate experiments across multiple frog specimens.
Frogs were particularly crucial to the study of muscles and nerves. This led to ever more violent encounters between experimenters and frog bodies. Italian scientist Luigi Galvani, for example, did experiments in the late 18th century on legs of frogs to investigate what he thought of as “animal electricity”.

In this sense, frogs were valued as significant scientific objects, their value lying in their flesh, their nervous systems, rather than in their status as living, feeling beings in the world.
In time, experiments with frogs moved beyond the laboratory into the classroom. In the 1930s, schoolchildren were expected to find frogs and bring them to school for dissection in biology classes.
This practice was, however, somewhat controversial, with opponents expressing sentimental attachment to frogs and concerns that such animal cruelty would lead to barbarism.
Recognising the fragility of frogs
So, our relationship with frogs is complicated. From the frogs of Aesop’s Fables to the meme Pepe the Frog, we have projected our own feelings and frustrations onto frogs, and exploited them for science and education.
Frogs have also borne the brunt of our failures as environmental stewards.
Climate change is also making life hard for many species. In 2022, over 40% of amphibian species (of which frogs and toads are by far the largest group) were threatened with extinction. Their vulnerability has seen the frog – especially the red-eyed tree frog – become a symbol for the environment more generally.
So we should delight in frogs and marvel at how beautiful and special they are while we still can, and consider how we might help save them.
Something to reflect on next time you are lucky enough to spot a frog.
The UK Labour party has announced its intention to reduce its £28 billion green investment pledge to less than £15 billion if elected this year. The political fallout has been been largely focused on the party’s fiscal credibility and leader of the opposition Keir Starmer’s seeming proclivity for U-turns.
A crucial question so far overlooked is what impact the cut would have on public health. The initial pledge included a key home-insulation plan to upgrade 72% – 19m homes – of the UK’s housing stock.
The revised plan, however, replaces that ambitious target with the more ambiguous statement that “millions of homes” will be refurbished. Research has long shown that uninsulated homes have consequences for health, especially for those living in poverty and in poor quality housing. This in turn places an extra burden on an already over-stretched health service.
Labour plans to build 1.5 million homes. Shutterstock
Existing government failure
The wider societal cost of poor-quality housing in the UK is estimated at £18.6 billion a year. Such costs, however, are often ignored when housing policy is being developed and implemented.
Labour promises to deliver 1.5 million homes by “blitzing” the planning system, but it has so far ignored the potential consequences for public health.
Of course, the failure to factor in health is by no means unique to Labour policy. It is already embedded in the government’s approach. A recent academic review of government housing and transport policy found that health is notably absent, despite well-established evidence that urban spaces are making us ill. This shows that on the occasions where health is included, it is lower in a hierarchy of priorities compared to other agendas such as growing the economy.
For many years, government housing policy has been shaped by the numeric gap between supply and demand, rather than the type or quality of the housing stock. The mechanisms for delivering have been based on land release and planning reform. Successive housing policies have mentioned involving communities and supporting their health, social, and cultural wellbeing. But there have been no clear targets for ensuring house retrofit and house building positively impact public health.
In his 2010 independent review on how to reduce health inequalities in England, epidemiologist Michael Marmot showed that prioritising health in urban policies, like housing and transport, can have significant health benefits for local populations.
Our research project has shown that health should be made a central factor in all national policy and guidance that shapes urban spaces. The World Health Organization recommends explicitly including health in housing policy – and tracking its impact with recognised metrics. UK politicians have largely failed to respond.
Promising developments
In addition to positive developments in government, such as the Build Back Beautiful Commission, the opposition also has some promising ambitions. Labour is pledging to deliver a “prevention-first revolution”, in which it envisions a pro-active role for government in ensuring that everybody has the building blocks for a healthy life.
In its mission document for health policy, Labour says that retrofitting of millions of homes will “keep families warm rather than living in damp, mouldy conditions that give their children asthma”. The fact that the party is making explicit this link between housing and health signal is a potentially very positive step forward.
However, in all the furore about Labour scrapping its £28 billion pledge, this crucial link to public health has been entirely forgotten. Indeed, while Labour’s environmental policy has been carefully updated to revise and remove various targets, the preventative health agenda retains the now defunct promise to “oversee retrofitting of 19 million homes”. This is perhaps indicative of the extent to which policymakers just don’t think about health when they think about housing.
While the Conservative pledges for the next parliament remain unclear, analysis of their existing policies in government has found a failure to think about or measure the way housing and urban development policis impact health. Instead, it is merely assumed that housing policies will have positive health outcomes. Rather than making such assumptions, policymakers should be putting public health considerations at the centre of all their decision making.
To ensure that the impact any given policy has on public health is measured and acted upon, health needs to be an explicit urban planning policy outcome. It needs to be clearly defined, measurable, and built into policy implementation and political discourse.
It is also important that different government ministries and relevant stakeholders focused on public health, planning and the environment work together more effectively. Unhealthy homes should be a priority for both the housing minister and the health minister.
Healthier people are more economically productive. They have a smaller financial footprint on the NHS. In the long term, better preventative health is a key part of solving some of the UK’s biggest economic challenges, from labour shortages and sluggish productivity growth to stretched public finances.
Too often government policy is not often designed with the long-term in mind. Instead, short-term economic outcomes and political gains are prioritised – to the detriment of public health.
The best way for the government to protect public health is for every department to consider how their work impacts on it. If political and economic calculations about creating, scrapping and rescaling major projects continue to ignore health, however, politicians are likely to continue coming up with the wrong answers.
Peat is a natural carbon sink but is often found in house plants and other retail products, particularly within the food and farming industry. New Africa/Shutterstock
During the long, solitary days of lockdown, I found solace in raising houseplants. Suddenly stuck at home, I had more time to perfect the watering routine of a fussy Swiss cheese plant, and lovingly train our devil’s ivy to delicately frame the bookcases.
But I started noticing that these plants, sourced online, often arrived in the post with a passport. Most had travelled from all over Europe, with one common tagline: contains peat.
As a peatland scientist, these labels instantly filled me with horror. Hidden Peat, a new campaign launched by The Wildlife Trusts, is now highlighting the presence of peat in all sorts of consumer products, including house plants.
Peatlands, such as bogs and fens, store more carbon than all of the world’s forests combined. They trap this carbon in the ground for centuries, preventing it from being released into the atmosphere as greenhouse gases that would further warm the climate.
Peatlands have multiple environmental benefits. They are havens for wildlife, providing habitat for wetland birds, insects and reptiles. They supply more than 70% of our drinking water and help protect our homes from flooding.
So why on earth is peat being ripped from these vital ecosystems and stuffed inside plant pots?
From sink to source
Despite their importance, peatlands have been systematically drained, farmed, dug up and sold over the last century. In the UK, only 1% of lowland peat remains in its natural state.
Instead of acting as a carbon sink, it has become one of the largest sources of greenhouse gas emissions in the UK’s land use sector. When waterlogged peat soils are drained, microbes decompose the plant material within it and that results in the release of greenhouse gases such as methane into the air.
Most of the peat excavated, bagged up and sold in the UK is used as a growing medium for plants. Gardeners have become increasingly aware of this problem. Peat-free alternatives have been gaining popularity and major retailers have been phasing out peat-based bagged compost in recent years.
Indeed, the UK government announced they would ban sales of all peat-based compost by 2024. But this legislation has not yet been written and it seems unlikely it will be enacted before the end of the current parliament.
Even if brought in to law, this ban would only stop the sales of peat-based bagged compost of the type you might pick up in the garden centre. Legislation for commercial growers is not expected until 2030 at the earliest. So the continued decimation of the UK’s peatlands could remain hidden in supply chains long after we stop spreading peat on our gardens.
Hide and seek peat
For consumers, it’s almost impossible to identify products that contain peat or use peat in their production. All large-scale commercial mushroom farming involves peat and it is used for growing most leafy salads. It gives that characteristic peaty aroma to whisky, and, as I found out, is a popular growing medium for potted plants.
But you’d struggle to find a peat-free lettuce in the supermarket. The Hidden Peat campaign asks consumers to call for clear labelling that would enable shoppers to more easily identify peat-containing products. Shoppers are also encouraged to demand transparency from retailers on their commitment to removing peat from their supply chains.
You can ask your local supermarket about how they plan to phase out peat from their produce. Some supermarkets are actively investing in new technologies for peat-free mushroom farming.
Make informed purchases by checking the labels on garden centre potted plants or source plants from peat-free nurseries. The Royal Horticultural Society lists more than 70 UK nurseries dedicated to peat-free growing.
You can write to your MP to support a ban on peat extraction and, crucially, the sale of peat and peat-containing products in the UK. That ensures that peat wouldn’t just get imported from other European countries.
Pilots and progress
The UK government recently announced £3.1m funding for pilot projects to rewet and preserve lowland peat, with peat restoration seen as a cornerstone of net zero ambitions. This campaign calls for further acceleration of peatland restoration across the UK.
As a research of the science behind peatland restoration, I see firsthand the enormous effort involved in this: the installation of dams to block old agricultural drainage ditches, the delicate management of water levels and painstaking monitoring of the peat wetness.
I spend a lot of time taking samples, monitoring the progress, feeding results back to the land managers. Like many other conservationists, I work hard to find ways to preserve these critical habitats.
But sometimes, there may be a digger in the adjacent field doing more damage in a day than we could undo in a lifetime. That’s the reality, and the insanity, of the UK’s current peatland policies.
We heavily invest in restoring peatlands, yet fail to ban its extraction – the one action that would have the most dramatic impact. By demanding that peat is not only eradicated from garden compost, but weeded out of our supply chains, we can keep peat in the ground, not in pots.
Examining some of the Fund’s shortcomings and putting things into perspective after COP 28
COP 28, the latest United Nations Climate Conference, came to an end in December 2023. It began with an agreement to launch the loss and damage fund, which was kick-started by the UAE’s $100 million pledge. A further 15 countries followed suit, making pledges of varying amounts, and by 2 December 2023, a cumulative total of $655.9 million had been pledged to the loss and damage fund.[1] The fund has been heralded by many as the biggest success of the entire conference and a historic agreement – being the first time that a substantive decision was adopted on the first day of the Conference. The delegates of nations present from around the world, rose in a standing ovation when the agreement was passed.
However, although the loss and damage fund is an important and long overdue step towards getting vulnerable countries and communities funding they require, it may be too soon to be rejoicing, with many of the details regarding the fund’s set-up being highly controversial.
A brief background to the loss and damage fund
The loss and damage fund was first agreed to at COP 27 last year, after more than three decades of pressure from developing countries disproportionately affected by the irreversible and adverse consequences of climate change calling for funding to help them pay for the losses and damages suffered as a result of the escalating climate crisis. These impacts range from, and are caused by, increasingly frequent and more extreme weather events, as well as slow-onset events, including sea-level rise, increasing temperatures, ocean acidification, glacial retreats, loss of biodiversity, land and forest degradation, salinisation and desertification. These endanger human security and health, destroy homes, disrupt agriculture and threaten water and food security in ways that are often unequally distributed.
As one of the outcomes of COP 27, a Transitional Committee was established and, in the lead up to COP 28, they met several times to negotiate the operationalisation and the details of the new funding arrangements. In less than a year, the Transitional Committee were able to report back with its recommendations and its text was subsequently passed at COP 28, with no objection by the parties. After almost no momentum for thirty years, the progress made in less than a year is a remarkable feat.
Examining some of the shortcomings
While funding for climate disaster loss and damages is vital and certainly hard fought for, one should be hesitant before deeming it a substantive win for developing countries.
Inadequate and duplicate pledges
Although $655.9 million may at first glance appear like a significant amount of money, it is in fact relatively insubstantial when one considers that it is estimated that more than $400 billion is suffered in losses by developing countries each year,[2] a figure which is expected to grow as the impacts of climate change grow worse. The current funding will therefore cover less than 0.2% of developing countries’ annual needs. It has therefore been recommended that $400 billion be used as a baseline and revised upwards over time to meet increasing needs.[3] Furthermore, how to actually implement the pledges that have been made poses its own issue. This is a problem that previous funds, such as the Green Climate Fund, have faced and it is an issue that will need to be tackled to ensure that the pledges made do not simply turn out to be more broken promises. Moreover, approximately $115.3 million of the total amount pledged to date will go towards setting up the fund rather than directly to beneficiaries of the fund.[4] Future pledges to the fund may make this operational expense insignificant, but it is still uncertain how much money will go into the fund and where it will come from. In addition, campaigners pointed out that some countries, such as the United Kingdom, were simply re-pledging money that they had already committed to, rather than offering new or additional funding.[5] In this way, the United Kingdom are simply re-branding existing forms of climate finance or development aid so as to appear to be contributing.
Moreover, the amount pledged by some countries has been criticised for being inadequate. In particular, the United States, the world’s largest historical emitter[6] and the largest producer and consumer of oil and gas in 2023,[7] pledged only $17.5 million, an amount that still needs to be approved by Congress and accordingly hinges on the political climate and the upcoming elections. When viewed against the billions of dollars of undelivered climate finance that the United States owes to developed countries as part of its share of the annual $100 billion climate finance goal committed to by developed countries in 2009, this amount of $17.5 million certainly appears limited.[8] Of the $43.51 billion the United States owes, as part of its fair share of the $100 billion goal, only $9.27 billion has been provided to date, being a measly 21% of its targets.[9]
It is also very telling as to what the United States’ priorities are when the $17.5 million pledged by the United States to the loss and damage fund is compared to the estimated annual $20.5 billion in fossil fuel subsidies distributed by the United States government each year,[10] contributing to the cumulative amount of $7 trillion in fossil fuel subsidies in 2022.[11]
Historical responsibility and voluntary contributions
During the negotiations that the Transitional Committee had leading up to COP 28, the United States, Australia and Canada all insisted that the loss and damage fund be de-linked from liability or compensation. This is in keeping with previous stance adopted by developed countries, particularly with that of the United States, who insisted that this wording be included in the decision on the adoption of the Paris Agreement which noted that loss and damage was “not a basis for liability or compensation”.[12] As the historically greatest emitters, developed countries have long opposed the establishment of the loss and damage fund over concerns that it would open the door to legal liability and compensation. Due to this refusal to assume historical accountability, communities who are experiencing the worst impacts of climate change have been forced to shoulder the consequent costs of loss and damage suffered, even though many of them, such as the Pacific Small Island Developing States, have contributed very little to climate change. This goes to the issue of equity and responsibility for the climate crisis, a sensitive topic which makes developed countries defensive. Instead of framing loss and damage in terms of responsibility and liability, wording was included in the agreed text stating that the fund is based on cooperation and facilitation.
The approved text also stops short of demanding any payments, with the United States having fought to ensure that the contributions should remain voluntary, and the text indicated that developed countries ought to “take the lead” on providing seed money. The text “urged” developed countries to contribute to the fund, while other developing countries are “encouraged” to provide support “on a voluntary basis”.[13] The United States, Australia and Canada further insisted that contributor countries include presently high-polluting nations such as China, India, Russia and Saudia Arabia, and that only the least developed countries be eligible to benefit from the fund. As a result, high polluter states are not obligated to make any payments into the fund and instead of framing the contributions in terms of countries’ responsibility for the majority of greenhouse gas emissions, they are framed as donations made out of generosity and charity.
The World Bank as the interim host of the Loss and Damage Fund, the set-up of the Fund’s governing board and the structure of funding
Who would host and administer the new fund was a politically contentious sticking point in the discussions leading up to COP 28. Less than a month before COP 28, at a final and impromptu meeting called by the Transitional Committee, this matter was hastily decided. Developing countries wanted the loss and damage fund to operate as an independent United Nations body and were resistant to it being hosted by the World Bank, which many poorer countries see as an economic policy weapon wielded by the industrialised world.
The World Bank was established by colonial powers and is known for having historically spread pro-Western ideologies and policies.[14] Moreover, it is housed in Washington DC, is headed by a US citizen, appointed by the government of the United States, as its major shareholder,[15] and has a history of operating as an Untied States policy tool. In addition, concerns were raised that the World Bank would be charging high hosting fees, has a weak climate change record and that having it host and administer the loss and damage fund would compromise the fund’s independence and give developed countries the influence over who receives the funds and who doesn’t. Developing countries eventually caved under the United States’ insistence that the fund be hosted and administered by the World Bank, and it was agreed that the World Bank would act as an interim host, provided that the World Bank would agree to certain conditions. This arrangement is to be reassessed in four years, which will result in either the fund being made fully independent or continuing as a permanent hosting situation under the World Bank.
The United States has argued that there are practical reasons for placing the loss and damage fund under the auspices of the World Bank, and that the fiduciary experience the institution has, places it in the best position to deliver money to state beneficiaries. However, given the World Bank’s donor-recipient and loan-driven business model, reservations have been expressed as to whether developed donor countries would have a disproportionate influence, even though the Transitional Committee has recommended that the fund’s governing board have a majority of developing-country members. Although this sounds positive, the board’s composition is limited to national representatives, meaning that civil society representatives such as members of Indigenous groups, are automatically excluded.
Another concern regarding the World Bank, is high overhead costs, with the administrative fees of the World Bank rising and likely to absorb a large portion of the funding meant for the fund’s beneficiaries. Further, developing countries have consistently called for funding to be in the form of grants, rather than debt and loan financing, which would only deepen the debt crisis and increase developing countries’ burden, which is the traditional model of financing employed by the World Bank. The agreed text stipulates that “the Fund will provide financing in the form of grants and highly concessional loans”.[16]
The ultimate success or failure of the loss and damage fund still hangs in the balance
In order to retain any faith in the international climate policy process, there needs to be follow-through on both the pledges and commitments made. To date, climate finance has not had the best track record. Other funds, including the Green Climate Fund and the Adaptation Fund, have been radically under-resourced from the get-go and climate finance has grown at an annual rate of only 7%, which is less than half of the cumulative annual growth of 21% which is required until 2030.[17] In order for the Loss and Damage Fund to be effective, the scale of the funding will need to be increased, as what has been pledged to date constitutes a mere 0.2% of what is actually needed.
There are also still a lot of questions to address, which the new Board of the Loss and Damage Fund will start to work through at its first meeting on 31 January 2024. Popular Gentle, the development management expert to the prime minister of Nepal, pointed out that while the establishment of the loss and damage fund is a promising start, that applause should be reserved for the time being, saying “our concern is we are excited about the establishment of the loss and damage fund. We are still cautious that the same story will be repeated. We need easy, equitable, accessible loss and damage funds without any procedural difficulties”.[18]
So far, there are already some concerning issues that have arisen out of what has been decided. The issues that still need to be determined will prove critical to whether the fund’s operation is a success or a failure. These issues include the fact that there are no specifics yet on the scale and scope of funding, the financial targets or how the loss and damage fund will be funded going forward – although the text provides that contributions will come from a “variety of sources”.[19] The current language included in the agreed text merely invites developed nations to “take the lead”[20] in providing finance and encourages other developing country parties to make commitments. There is also little clarity regarding the performance indicators and who will be eligible to receive funding or precisely what type of climate loss and damages will qualify. Another issue will be how the application procedure will work and how quickly countries who need it will be able to access the funds and whether they will encounter any procedural difficulties in doing so. Until these things are decided, it is simply too early to greet the loss and damage fund with anything other than a mixture of cautious optimism and healthy scepticism.

With carbon emission of around 25tCO2 per capita (global average around 4.5tCO2eq per capita) and energy demand of around 150MWh per capita (global average around 20MWh per capita), both among the 5 highest in the world, the UAE is on a per capita basis one of the largest contributor to climate change. And the host of COP28, the 28th Conference of the Parties, the main decision-making body of the UNFCCC. This makes uncomfortable reading, especially given the lack of progress in tackling human-made climate change. Then again, it probably does not matter where COPs are held as it is the agreements which countries commit to, and their success in fulfilling these commitments, which ultimately count. The number of fossil fuel business representatives makes equally uncomfortable reading. But maybe the number of fossil fuel lobbyists is a sign that they are taking COPs more seriously and rightly recognize strong action on climate change as a challenge to business as usual. Their desire to have their voices heard is testament to their recognition of the importance the UNFCCC’s process and progress on climate policy more generally.
The event itself, meanwhile, was discombobulating. Dubai’s geography of nowhere which robs you of any sense of scale and place is replicated in its Expo2020 site where COP was held. Huge distances between everything and the closed doors behind which languished side events and pavilions, mainly of countries but also of non-governmental organisations, multinational development banks, even universities, were the polar opposite of a bazaar where exchange was facilitated at previous COPs and in the space of 100 meters you might come across the International Labour Organisation, the World Bank, Egypt, Japan, Zambia, and Portugal. Thus, COP28 was sapped of interaction where browsing is enabled, chance facilitated, and happenstance happened. Instead, it felt strangely disjointed, more like an in-person zoom conference in the desert.
But the food was good, if expensive, the streets eerily safe and clean, the organization well executed, the venue shiny and spotless, public transport clean and efficient, water plentiful, and the sun reliable. It is hard to imagine impoverished countries not choosing a similar development trajectory if they were provided the opportunity. According to some calculations, African countries are sat on $10trn worth of hydrocarbons capable of pursuing such a development trajectory while pushing global warming to 6-7 degrees above pre-industrial levels. But which alternative development trajectory are we supporting which keeps these hydrocarbons in the ground while improving living standards and increasing opportunities? Access to climate finance is essential, while debt relief is the elephant in the room (I wonder how this analogy will read if we tacitly enable their extinction through poverty?). Calculations suggest that sentencing debt costs the 58 countries that make up the Vulnerable Twenty (V20) over £100bn/a. This sum would go a long way towards greening development and keeping hydrocarbons in the ground.
Instead, the Global Stocktake, the COP28 agreement, ‘calls on parties’ to ‘tripling renewable energy capacity globally and doubling the global average annual rate of energy efficiency improvements by 2030’. This is important as we need something to replace fossil fuels the Stocktake agrees to ‘transition away from’ and coal especially which it agrees to ‘phase-down’. While it will be virtually impossible to eliminate fossil fuels entirely from our economies, this language emphasizes the need to reduce their stranglehold on our energy systems. With emphasis placed on renewables and energy efficiency, this provides a plausible, just, and equitable transition pathway. While the statement that ‘abatement and removal technologies such as carbon capture and storage’ should be accelerated leaves a loophole for abated fossil fuel technologies, it emphasizes its use ‘in hard-to-abate’ sectors such as steel and cement. This loophole is to bring on board countries with very high fossil fuel dependence, not just for power generation but as the foundation of their entire economic prosperity.
Regarding transport, the document emphasizes the ‘reduction of emission from road transport on a range of pathways, including through development of infrastructure and rapid deployment of zero and low-emission vehicles’. This reference to infrastructure is highly relevant as it refers to mass transit systems which, according to the Intergovernmental Panel on Climate Change, are far more efficient than electric vehicles for example. Finally, ‘phasing out inefficient fossil fuel subsidies that do not address energy poverty or just transitions, as soon as possible’ should act as a financial driver of this transition. According to the International Monetary Fund, such subsidies amount to $7tn per year, or 7.1% of GDP. This implies that governments around the world effectively subsidise every tonne of CO2 emitted to the amount of $125. If we used this money to subsidise renewable energy and energy efficiency, as well as abatement in hard-to-treat sectors and eventually removals to account for historical emissions, 1.5 degrees is still alive, and African countries for example could be placed on a clean development trajectory towards prosperity and opportunity.
Despite tentative progress, however, parties failed to agree on the modalities of Article 6. Article 6 is the last building block of the Paris Agreement which has yet to be agreed on, with a rulebook in place that all parties agree on. Apparently, a bloc led by the US favours a light-touch approach akin to voluntary carbon markets. Unsurprisingly given their discreditation in recent months, a bloc involving the EU an African and Latin American states favours stronger checks and balances to avoid the creation of junk credits and discreditation of all market mechanism. A lot is at stake. Under the Clean Development Mechanism (CDM), the predecessor of Article 6, over £200bn was channelled into Chinese wind energy. For all its flaws, the CDM in this particular case supported the development of a renewable energy industry in a country which barely had a wind turbine installed when it came into force. Market mechanisms are powerful instruments which are difficult to guide but their potential to incentivize climate finance is evident.
To deliver the objectives of the Global Stocktake and the Paris Agreement, we need mechanisms to avoid free-riding which occurs when countries benefit from ambitious net zero emission mitigation activities in other countries without contributing to the cost. If market mechanisms are operationalised through climate clubs, this issue of free-riding can be overcome. This enables ambition to be raised and collective action to be supported. Yet significant efforts are required to ensure that poor countries can benefit while excludable benefits are sufficient to ensure integrity and support higher ambition in climate change mitigation. The stakes are high and the Global Stocktake is a small but significant step in this direction. But a lot more climate diplomacy is necessary, alongside a collaborative spirit, to ensure that the transition away from fossil fuel is actions and that this transition is just.
I’d never given a huge amount of thought of what a dam manager did until I visited Pequenos Libombos dam in Mozambique in October 2023. Standing at the dam, in hot conditions, listening to the lived experience of people who work on the ground and explain what they do during a tropical cyclone leaves you with more understanding than any peer reviewed journal article. Context is everything. It’s why visiting the countries I’m researching is something I do given the chance.
That’s what members of Bristol projects REPRESA (co-led by Prof Elizabeth Kendon at University of Bristol & UK Met Office, Dr Luis Artur from Eduardo Mondlane University and Prof Francois Engelbrecht from University of the Witwatersrand) and SALIENT (led by Dr Rachel James, University of Bristol) did in October. The REPRESA project aims to understand compound tropical cyclone risks, impacts of tropical cyclones and improve early warning systems in Mozambique, Malawi and Madagascar. Seeing the research alignment in projects, the SALIENT team also joined. The SALIENT project aims to improve the characterisation and communication of future climate information for national adaptation planning in southern Africa.
On the field trip day, we travelled to Pequenos Libombos dam and heard from a government official from the Vila De Boane Municipality. It was this day where I had my epiphany that if I ever left academia, dam management is not my calling. Providing water to the local population is the dams primary role and it provides 2 million people within Maputo Province with access to water. That is more than 4 times the population of Bristol.
The management of Pequenos Libombos dam is difficult as there are many other people and industries to consider and keep safe and happy when making decisions. From the businesses who want to use the dam’s water for industrial purposes to the farming communities that are reliant on the water for irrigation, and hydroelectricity companies that want to use the dam to create energy to the communities downstream that may be flooded if the dam releases water too quickly. The dam catchment is also shared with 2 of Mozambique’s neighbouring countries; eSwatini and South Africa, adding another element of complexity to the dams management.
Management must carefully balance both periods of water surplus and deficit and Maputo has experienced numerous extreme weather events in recent years. The 2015-2016 southern African drought impacted Central and Southern Mozambique and more recently the remnants of tropical cyclones in 2019, 2011, 2022 and 2023. During February 2023, Tropical Cyclone (TC) Freddy passed over Madagascar and southern Mozambique before returning a couple of weeks later to central Mozambique. It is thought to be the longest lived and have the highest accumulated cyclone energy of any cyclone on record, awaiting formal investigation from the World Meteorological Organization. Although TC Freddy didn’t directly pass over Pequenos Limbombos, its associated rainfall resulted in 250 mm of rainfall at the dam in one day. For context, the Bristol experiences 265mm rainfall, on average, in October, November and December combined. To avoid a breach of the dam, discharge was released at the maximum rate, which is more than 500 time more than normal.
Globally there is evidence that TCs and their impacts are being impacted by climate change. The frequency, intensity and storm tracks of TCs may be changing meanwhile, rising sea levels may lead to higher storm surges. Yet we know a limited amount about how tropical cyclones may act in a future with increased global sea surface and air temperatures. TCs in the Indian Ocean are particularly under researched, but recent and frequent events have highlighted the importance of understanding TCs in a changing climate.
After hearing about the vast amount of rain that fell in February 2023, we walk past the disused hydroelectric generator that was forced to cease operation during the drought as it was no longer economically viable. It really hammered home the complexities faced when trying to manage such a huge piece of infrastructure during extreme events. Similarly, it is clear why research projects like REPRESA and SALIENT are needed to understand how tropical cyclones may behave in the future and explore how early warning systems and climate change adaptation can be strengthened.
The human side of extreme weather
After the talk at Pequenos Libombos Dam, we visited the Municipality of Vila de Boane. Vila de Boane is located roughly 15 km downstream from the dam and the River Umbuluzi passes through the municipality. The municipality experienced large scale flooding after the dam was forced to increase to maximum discharge during the February 2023 rainfall.
Despite already hearing about TC’s Freddy’s impacts at the dam, they were not as focused on the human impact. The leader of the municipality compellingly described how 16,000 people were impacted overnight, 6000 people were displaced and 6 people sadly died. The community water pump was destroyed, leaving people without water for 3 months. The municipality leader said he had never seen that amount of water passing through the municipality at such high speed before. Meanwhile, money that had been budgeted for development initiatives, had to be redirected to repair and response. It was not clear if extra money had been sourced for the development initiatives.
It was also highlighted that the increased release of water from the dam occurred over night with little warning. The municipality had been told to expect “above normal” rainfall and to avoid being close to rivers and move farming machinery further inland. But as the municipality leader questioned, what does “above normal” actually mean? People will perceive this message differently, which will influence how they act upon it. As part of the SALIENT research project, I am researching how we best communicate future climate information to decision makers and this anecdote will stay with me. It’s clear that improved communications are needed in both weather and climate services, something REPRESA is also aiming to research further.
Reflections and collaboration
After hearing about the vast amount of impacts the flooding had on Villa de Boane, we waited for our transport back to Maputo under the shade as it was too hot to stand in the sun. It was clear everyone from the REPRESA and SALIENT teams, both physical scientists and social scientists, had taken a lot from the field day. There was discussion about what the research should consider as well as the different angles that could be taken. It also fostered collaboration, SALIENT team member, Alan-Kennedy Asser, is providing the REPRESA team with analysis of precipitation trends from a multiple ensembles of climate models to characterise the range in future projections over the region. Meanwhile I spoke with some REPRESA team members in more depth about future climate information and will be providing risk communication training session in the future.
My personal key take away is that understanding the context and hearing the lived experiences of people working and living with extreme weather events enriches me as a researcher. Similarly, collaborating with researchers and practitioners on different projects enhances your work by providing questions and inputs from different standpoints. And finally, I’m too indecisive a person to ever be a good dam manager.
