Professor, IRES. Director, First-year Seminar in Science

In 2011, I decided to use my sabbatical to make a major shift – it was time to concentrate on a topic of direct contemporary concern. Searching for an area where my deep knowledge in chlorine biogeochemistry, my broad knowledge of environment and sustainability related issues and my experience of interdisciplinary research and education could be useful. The use of scientific knowledge in environmental decision-making has been a  side-interest of mine since the start of my research career. I decided to make this my main focus and I settled on sustainable sewage management in growing urban areas. Why? The short answer is that diarrhoea is (still) the #1 child killer in the world. Surprised? Well, in 2012 about 1.5 million people died in diarrhoeal diseases, about half of them being five years old or younger. In comparison, the same year a total of about half a million people died in warfare.

Providing sanitation services is not only a challenge for the developing world. Aging infrastructure needs to be replaced most everywhere. Rapidly growing mega-cities need to provide services for new areas that are popping up in a haphazard manner. Provision of sanitation services requires that trade-offs are made that inevitably involve unequal distribution of risks and benefits. It is a typical example of a so called ‘wicked problem‘. Even so, it is handled as if it were purely a question of science and technology. Furthermore, it is an area where uptake of innovations is extremely slow and where most resort to the linear end-of-pipe solution developed at the end of the 19th century: Potable water is used to flush toilets via pipelines to a central facility. Intuitively, this seems like a waste of resources. Still, as much as 90% of research and development is dedicated to further develop the end-of-pipe solution even though it is evident that this solution will never be implemented for the 90% of the world’s population that are lacking basic sanitation services. It is simply too expensive. We need to find solutions that are sustainable.

What kind of knowledge is needed, used and trusted? How does the knowledge used impact perceived solutions? How does one make ‘expert knowledge’ more accessible without ‘dumbing it down’? How might we facilitate for decision makers and the public to ‘unpack’ assumptions, values and preferences that are embedded in such knowledge?

Front page of IRM report“Being an interdisciplinary graduate student throws up a number of unique challenges which can leave you feeling confused and frustrated. Professor Öberg’s book provides a life-line for those of us who are attempting interdisciplinary research. Its practical student case-study format is helpful, especially when the last thing you need is another dense theoretical tome critiquing approaches to interdisciplinarity. It is clear that Professor Öberg has extensive experience of being an interdisciplinary researcher and guiding students through this PhD pathway.”

Research

In addition to my research on the use of scientific knowledge in environmental decision making (described above), I carry out research in two additional fields:

Interdisciplinary higher environmental education Originally, I planned to become a high-school teacher but I got so annoyed with the poor education I received at so I dropped out. Instead, I went for a career in environment and sustainabilty. The question ‘what makes an education poor/good’ has, however, followed me ever since. Throughout my undergraduate and graduate studies, I sat on various committees, went to workshops and the like. In 1997, I got the opportunity to put my ideas to practice as I was asked to lead the development of a new undergraduate program in environmental studies at Linköping University, Sweden. Through this very inspiring collaborative project, I started to carry out research in the field and I am happy to note that our publications are steadily gaining in reputation, such as our 2001 paper “Questioning to learn and learning to question: Structure and function of PBL scenarios in environmental science education” and my  book “Interdisciplinary environmental studies – a primer”, published in December 2010 by Wiley & Blackwell, which is lauded as “a much needed practical hands-on guide book”.

I am presently director and instructor of the First Year Seminar in Science (SCIE 113), which is an award winning course that explores science as a way of knowing and is taught in eight parallel sessions. I am also part of the team developing and teaching the 4th-year capstone course Sustainability for the Community and the World that is open for students in both the Faculty of Science and the Faculty of Arts.

Chlorine biogeochemistry in soil. I have been carrying out studies on chlorine biogeochemistry since the end of the 1980s when I through my doctoral studies discovered that chlorine participates in a complex biogeochemical cycle in soil. These studies integrate knowledge from a number of disciplines such as biogeochemistry, soil science, analytical environmental chemistry, microbiology, enzymology and hydrology. My latest publication in the field scrutinizes the challenges involved in making rigorous estimates of soil-to-atmosphere fluxes of chlorinated organic volatiles and describes a chamber-based system designed to measure chloroform flux from terrestrial systems, providing a reliable first assessment of the spatial variability of flux over an area.
