As a result of the corona pandemic, the embedded practices of international travel in academia drastically changed. It suddenly became customary to replace business trips with digital alternatives whenever possible. Four students at SLU decided to study the implications. The results show a great untapped potential to reduce emissions from academic travel by conducting a larger share of academic activities digitally – without compromising the quality of research. 

In the turmoil that arose due to the travel restrictions put in place in March 2020, academics suddenly had to find solutions to continue their work in ways that did not include longer business trips. As students actively involved in discussions on universities’ greenhouse gas (GHG) emissions, we have for long been discussing the question of how academic business trips can be replaced by digital alternatives while maintaining the quality of work and research. 2020 presented an unexpected window of opportunity to seek an answer to that question and to gather academics’ experiences of the new reality without travels.

Academia in a burning climate crisis

The topic of GHG emissions from academia in general and academics’ air travel in particular has over the past decade been the focus of a growing number of publications in scientific journals and in mainstream media. This should be understood against a backdrop of factors such as i) the climate crisis itself,  ii) the notion of aviation as one of the fastest-growing sources of GHG emissions – characterised by a slow technological development unlikely to compensate for the estimated growth in demand, and iii) the recognition of academic researchers as among the highest emitters when it comes to international air travel, but also as potential leaders in a transition to a society within the planetary boundaries, if combining advocacy with changes in their own emission habits. This debate has resulted in various commitments, initiatives and responsibilities for higher education institutions (HEIs) around the world. With air travel being one of universities’ largest sources of GHG emissions, the need to critically scrutinise the norms and practices of academic travel is apparent. 

Prior to the pandemic, one could mainly speculate about the consequences of a drastic and large-scale reduction of travel in academia. University employees’ recently gained experiences of an increased use of digital solutions replacing longer business trips are therefore valuable in the search for new norms and practices of academic travel. In our study, we wanted to collect these experiences before they fell into oblivion. Through 25 semi-structured interviews and a survey with approximately 220 respondents, we sought to answer how employees at SLU experienced the cancellation of business trips and increased use of digital solutions. What trips worked well or not so well to replace? How was the quality of various academic activities (seminars, thesis defences, conferences, project meetings etc.) affected by being held digitally? 

Digital solutions replacing academic travel – what have we learnt? 

Our study shows that there is a great, untapped potential to reduce emissions from academic travel without compromising the general quality of the research and work. By adopting a more thought-through mix of digital and physical meetings, where a larger share of activities are conducted digitally, academia can reduce GHG emissions while keeping the quality as well as opening up for greater accessibility and participation.

A majority of the respondents were surprised by how well it had worked to replace longer business trips with digital alternatives, surprisingly well or beyond expectation were common formulations. An overwhelming majority (83%) of the survey respondents reported that their work in general had been mainly positively affected, equal parts positively and negatively affected, or not affected at all by the travel restrictions. 

Effects on work in general.

The academic activities that were experienced as most difficult to perform digitally were certain types of fieldwork and data collection, as well as activities that require spontaneous discussions and networking. We also found that meetings had become more efficient, but often at the expense of social interactions. On the other hand, well-structured meetings with a clear agenda between people that had previously met in person, as well as activities such as administrative meetings, project meetings and seminars, were perceived as most suited to perform digitally. These experiences were also mirrored in the survey respondents’ answers to what academic activities they thought could be held digitally – and to what extent – in the future. 

What type of activities the respondents believed could be replaced with digital solutions after the corona crisis and to what extent.

Furthermore, our results show how digital activities have enabled greater accessibility and equality within the academic community. Researchers that would not have had the time, resources or possibilities to travel to various meetings could now participate in digital events on more equal terms. On the other hand, lack of access to stable internet connection and issues of time differences made certain meetings less inclusive and/or equal. A key takeaway is therefore that digital events have the potential to be more inclusive than physical events but that it is important to actively consider equality and accessibility aspects in planning.

Another eye-opener following the increased use of digital solutions is how these were used to reach a wider audience with research and education. Instead of having farmers or beekeepers travel to SLU to listen to a seminar or to take part in a course, the material was recorded and made publicly available digitally. In a research project reference group consisting of farmers, more had been able to join the meetings now that they were held digitally, as opposed to before when the group had to travel to SLU for each meeting.

Our study also found that there seems to be a need to improve how we use digital solutions and start thinking beyond the mere translation of a physical event or meeting into a digital one. The informants had a lot of useful insights concerning this and we have summarised some of these insights in the figure below. 

Six hacks for successfull digital meetings.

Lastly, most informants lacked experiences of networking in digital events as this part had been neglected when events were digitised and they stressed a need for new and inventive ways of networking digitally, moving forward.

New ways forward for academia post-corona

The participants clearly did not want to continue travelling to the extent they had before the pandemic. However, no one wanted to completely move from physical meetings to only digital solutions. It is time we find a golden middle way. Many expressed that they had begun to think in new ways about what makes it important to meet in person and what makes a business trip necessary or not.

“I’m sure you can reduce the amount of physical meetings quite considerably, and that the [physical] meetings you do have you can spend some more quality and preparations at them so they are well motivated and so that you get the most out of them. ‘Which are the good conditions and perks of meeting in person?’ And then make sure to optimise them.” – Professor

Although the pandemic has closed countless doors, it should in some respects be seen as a window of opportunity to make new decisions and do things in new ways. An opportunity to address and rethink what is actually possible in terms of reducing academia’s GHG emissions.

“There are surely plenty of ways to do this that we have never tried, that might be better than what we are doing right now.” – Professor

Interesting questions remain: what will university managements as well as researchers make of this opening, what insights and new learnings will they bring with them into the future? Which new practices will stay on to become embedded within the culture of academia in a post-corona context?  We argue that the answers to these questions should lead to emission reductions in line with climate science. That decisions about what business trips actually are necessary are based on thorough evaluations of experiences from this pandemic, and that digital solutions are used strategically to replace longer business trips. The urgent climate crisis, combined with this unexpected window of opportunity, makes it crystal clear that the time for academia to change embedded practices, rapidly reduce emissions and take on a leadership role is now. Our study has shown that all of this can be done without compromising the quality of research. So what are we waiting for?

Antibiotics – a tragedy of the commons

Today is the Antibiotic Awareness Day. It is a day to be grateful for these important medicines, and to consider how to best preserve them for the future.

Antibiotics, drugs to combat bacteria, are useful tools in both veterinary and human medicine. They allow us to treat bacterial infections in animals and people, common diseases as well as those that occur due to immunosuppressive treatments such as cancer therapy or following transplant surgery. The problem is that all use of antibiotics kills the susceptible bacteria and leave the field open for those who have  become resistant to the antibiotic. In a successful treatment course, the few remaining (resistant) bacteria can be killed by the host’s immune system and the host, animal or person, is cured. On the other hand, if the majority of the disease-causing bacteria are resistant, the treatment will be ineffective.

To preserve antibiotics as medical tools, we must use them as little as possible, only when needed, in the correct dose so that enough of the drug reaches the body site where the bacteria are causing the disease, and only for the time needed, until the immune system has eliminated the disease-causing bacteria. This is not as easy as it sounds, it takes insight into what diseases cause problems in animals and people in different settings, how to prevent them and how to treat them effectively, with or without antibiotics.

In Sweden, disease prevention is a key feature of veterinary medicine. Good animal husbandry, good biosecurity, vaccination and other strategies to control and prevent disease has been and continues to be a major research focus. We also collaborate in EU projects where different practices, attitudes and societal systems present new challenges that can be addressed by learning from the Swedish experiences (successes as well as failures) and by new ideas and innovations.

In low-income countries, antibiotics are not restricted to prescription from a veterinarian or a doctor but can be bought over-the-counter in drug stores where the products can be of poor quality and the information about how to use them may be lacking or misleading.

Poor farmers sometimes use the volume intended for treatment of one animal to treat several animals (i.e. with a lower dose), rendering the treatment ineffective and paving the way for resistant bacteria without curing the disease. If no veterinarian is involved in determining the cause of the disease, antibiotics may be used to treat diseases that are not caused by bacteria, so that the treatment is a waste of money and, again, promotes the resistant bacteria.

We collaborate with researchers in low-income countries on how to prevent and control animal diseases. We also work on developing systems for monitoring of diseases and antibiotic use, to provide information about what diseases are common and which antibiotics are used effectively. This project also addresses ways to increase the interaction between veterinarians and farmers by video consultations, to facilitate farmers’ access to veterinary advice on disease treatments while improving profitability for both groups. 

It is important to recognise the need for different strategies in different settings, disease prevention and control rely on knowledge of the local situation and its context-specific challenges and opportunities. Still, the worries and hopes of farmers are similar in countries all over the world and serve as incentives for improvement of animal health and production. The long-term goals of our research focus on animal health and welfare, for a sustainable animal production with a sustainable use of antibiotics. We must all contribute to preserving antibiotics for the future. Don’t let it be nobody’s responsibility, it lies with everyone.

For the love of the spud in spite of its beauty spots

Today, 26 October, is the offical potato day here in Sweden and a good opportunity to look closer at this quite nutritional crop. The potato is grown and eaten all over the world and production is on the rise in many low income countries – primarily in Africa. The versatility and adaptability of this beloved spud is the key to it®s wide spread. However, diseases and drought due to changed climate present threats to yields in the future.

Potatoes have long been essential for Western cuisine. They are loved in many forms. Why not boiled together with meat and sauce, as fries accompanying that novel non-meat burger or simply as crisps, which can be seen as the centrepiece of cosy television time with the family. Worldwide potato is today the third most consumed crop.

The potato retains its popularity in spite the rise of the fast-boiling pasta and popularity of low-carb diets. Consumption in the industrialised world have been stable the last 20 years even if it now and again ends up in the dietary cold box.

In low-income countries, potato production is still on the rise though. In 2008, the total production even passed that of the industrialised world. Not the least in sub-Saharan Africa where incidence of malnutrition are among the highest in the world, and sadly more than 15% of the total population still lacks sufficient food.

In fact, its cropping area and production have increased more than those of any other food crop in Africa (1). Today, it is maybe foremost an important cash crop for small-scale farmers, but since the areal and demand are rising we can predict that it will have a greater importance to future food security in the region.

Potato has a fantastic ability to adapt and yield in different climate conditions. Originating from the Andes the potato is grown on all continents except Antarctica. Its ability to produce well in so many different environments is an important part of its success. Still many diseases affects the production. In temperate regions late blight is considered as one of the most dreaded plant diseases. Extensive research has gone into combating late blight and today we have both conventional bred and genetically modified potatoes carrying additional resistance genes with high level of resistance as well as efficient pesticides.

However, in an African perspective, other diseases such as early blight, which thrives in warmer climates and insect pests that destroy harvested tubers can cause larger problems. The underlying mechanisms of several other diseases than late blight are less studied and lesser known. Unfortunately, efficient resistance factors are unknown and remain to be discovered for use in breeding programmes. For early blight, there is also an increased problem with pesticide resistance.

For the small-scale farmers it is not easy to afford to protect their potato crop or take the right measures. One powerful way to convert research into practice are field demonstrations for farmers, advisers and policy makers, something we tried out with our colleagues Lerato Matsaunyane at the Agricultural Research Council in Pretoria, South Africa and Tewodros Mulugeta at Kotebe Metropolitan University in Ethiopia.

Furthermore, for the farmers in Southern Africa, unpredictable rains have caused big problems for agriculture. In this context, potato will have a challenge as it is sensitive to drought, also to shorter micro-droughts and clearer focus on research on drought tolerant varieties is needed. Unfortunately, climate change is expected to have a very large impact on agricultural production in sub-Saharan Africa. The need for a future drought tolerant potato is evident.

Luckily, the International Potato Center and other research institutes are doing multifaceted research to provide a disease free and drought tolerant potato suitable for different needs in African agriculture.

But, today is the official potato day here in Sweden, so let us just for a moment look away from these beauty spots of this loved spud. Did you for example know that the nutritional value of potato is not that bad! Tubers harbours fibre and important nutrients such as vitamin C, tocopherols and carotenoids! And with the right cultivar under the right conditions it can be one of the most high-yielding crops! With a production of 15, 40 or even 60 tonnes per hectare it can for sure feed many hungry stomachs.

Smallholder farmers in Kenya know how to meet climate challenges, but lack the means to do it

This article was written and first published by SIANI in collaboration with PhD Ylva Nyberg, Department of Crop Production Ecology, SLU. The ïŹndings and conclusions in this blog post are those of the authors and do not necessarily represent the views of SLU.

Many smallholder farmers in sub-Saharan Africa are caught up in a negative spiral. Often farming on one hectare of land, they struggle to make ends meet and, in most cases, they cannot afford enough farm inputs, which leads to declining soil fertility of their farms, resulting in low yields. Many farmers have to look for casual jobs to get by. Poverty pushes them to reduce the number of meals they eat, so they also lack the energy to farm.

Climate change with its changing rain patterns, droughts and floods doesn’t make the life of smallholder farmers easier. Contrary to the popular belief, recent research by Ylva Nyberg, highlights that smallholder farmers are well aware of the climatic challenges and know how to adapt and cope. However, they would be reluctant to adopt sustainable agricultural practices due to the lack of access to credit, land, knowledge and labour.

Nyberg carried out her field work on smallholder farms across a gradient of landscapes in Kenya, from Kisumu by Lake Victoria to Trans Nzoia in the western highlands. She summarized her findings in her PhD dissertation which she defended at the Department of Crop Production Ecology at the Swedish University of Agricultural Sciences, SLU. 

Initially, Nyberg embarked on her journey to gain a better understanding of how small farms can increase yields without damaging nature. She used a variety of research methods, such as group and individual interviews, tree density measurement, soil sample analysis and randomized control trials. During the group interviews, Nyberg explored whether the farmers had experienced rainfall-related challenges and if they had planned to adapt to changing rainfall patterns. She quickly learnt that smallholders were well aware of climatic changes and also knew many adaptation and coping strategies, though men happened to be better informed than women

Then Nyberg spoke with farmers individually to find out how they applied their knowledge of adaptation measures. The results varied in accordance with access to social capital. Men tended to have higher education, better access to agricultural advisory services and more time for social networking, and they also were able to use more adaptation measures than women, especially those who lack education. Farmers with regular access to agricultural advisory services used more adaptation measures, especially those measures that they perceived most effective.

During these interviews many farmers also mentioned that having trees and livestock makes them less vulnerable, providing insurances or savings. Therefore, Nyberg has also considered these parameters in her work. It appears that higher tree density increased the workload on farms, but the income that came from these farms was higher too. In addition, trees were important to all farmers by providing shade for recreation. High livestock density showed signs of higher soil nitrogen turnover, even though collecting and using the manure can be challenging. Low tree and low livestock density were often an indicator of high dependency on off-farm revenues.

Lastly, Nyberg compared farms that took part in Kenya Agricultural Carbon Project over four years with those farms that weren’t engaged in carbon farming. She found that maize yields were positively related to terracing of fields and to growing more trees on the farm, the so-called agroforestry. Farmers working with the Carbon Project used more sustainable management practices, had higher yields and better food self-sufficiency as well as more savings than farmers who weren’t involved in the project.

However, the farmers who participated in the Carbon Project had higher yields to begin with and the difference in yield between the two groups of farms were similar in the first and the fourth year. Thereby, the increases in yield cannot be explained by the project only, unless the neighbouring farms outside the project had actually learnt methods and started practising them as well.

Smallholders have great potential to improve their production in a sustainable way, but they lack sufficient labour, land, money or knowledge to adopt sustainable agricultural land management practices.

Nyberg suggests that policy should address the farming and food production system as a whole, increasing inclusivity, particularly in regards to women with poor education. Agricultural advisors should also promote packages of simple but effective measures, encourage diversified farming systems where feasible and focus on the limiting factors, such as access to credit, knowledge and labour. This way, farmers will have the means to practice sustainable agriculture. Only then smallholder farmers will be able to build sustainable livelihood, supply ecosystem services and be climate action agents.
