Crafting mines from satellite images

By Victor Maus, alumnus of the IIASA Ecosystems Services and Management Program and researcher at the Vienna University of Economics and Business

The mining of coal, metals, and other minerals causes loss of natural habitats across the entire globe. However, available data is insufficient to measure the extent of these impacts. IIASA alumnus Victor Maus and his colleagues mapped more than 57,000 km² of mining areas over the whole world using satellite images.

Our modern lifestyles and consumption patterns cause environmental and social impacts geographically displaced in production sites thousands of kilometres away from where the raw materials are extracted. Complex supply chains connecting mineral mining regions to consumers often obscure these impacts. Our team at the Vienna University of Economics and Business is investigating these connections and associated impacts on a global-scale www.fineprint.global.

However, some mining impacts are not well documented across the globe, for example, where and how much area is used to extract metals, coal, and other essential minerals are unknown. This information is necessary to assess the environmental implications, such as forest and biodiversity loss associated with mining activities. To cover this data gap, we analyzed the satellite images of more than 6,000 known mining regions all around the world.

Visually identifying such a large number of mines in these images is not an easy task. Imagine you are flying and watching from the window of a plane, how many objects on the Earth’s surface can you identify and how fast? Using satellite images, we searched and mapped mines over the whole globe. It was a very time-consuming and exhausting task, but we also learned a lot about what is happening on the ground. Besides, it was very interesting to virtually visit a vast range of mining places across the globe and realize the large variety of ecosystems that are affected by our increasing demand for nature’s resources.

The result of our adventure is a global data set covering more than 21,000 mapped areas adding up to around 57,000 km² (that is about the size of Croatia or Togo). These mapped areas cover open cuts, tailings dams, piles of rocks, buildings, and other infrastructures related to the mining activities — some of them extending to almost 10 km (see figure below). We also learned that around 50 % of the mapped mining area is concentrated in only five countries, China, Australia, the United States, Russia, and Chile.

Examples of mines viewed from Google Satellite images. (a) Caraj\'{a}s iron ore mine in Brazil, (b) Batu Hijau copper-gold mine in Indonesia, and (c) Super Pit gold mine in Australia. In purple is the data collected for these mines (Figure source: www.nature.com/articles/s41597-020-00624-w).

Using these data, we can improve the calculation of environmental indicators of global mineral extraction and thus support the development of less harmful ways to extract natural resources. Further, linking these impacts to supply chains can help to answer questions related to our consumption of goods. For example, which impacts the extraction of minerals used in our smartphones cases and where on the planet they occur? We hope that many others will use the mining areas data for their own research and applications. Therefore, the data is fully open to everyone. You can explore the global mining areas using our visualization tool at www.fineprint.global/viewer or you can download the full data set from doi.pangaea.de/10.1594/PANGAEA.910894. The complete description of the data and methods is in our paper available from www.nature.com/articles/s41597-020-00624-w.

Give yourself a nudge and make smarter decisions

by Ralph L. Keeney, IIASA alumnus and Professor Emeritus at Duke University

Ralph L. Keeney is a professor and consultant about decision-making. He was a research scholar at IIASA from 1974-76, where he and Howard Raiffa finished their book Decisions with Multiple Objectives. Here he describes his most recent book, Give Yourself a Nudge: Helping Smart People Make Smarter Personal and Business Decisions, and how it can impact you.

Few individuals understand the key role of decisions in one’s life. That is because many things other than decisions can increase the quality of your life. If you improve your professional skills, including your decision-making skills, you will get more job opportunities and end up doing more interesting work with better pay. If you regularly exercise and eat a better diet, your fitness and health will improve. Of course this is true, but none of this could happen without initially making decisions to improve professional skills, to exercise regularly, or to eat a better diet, and then making the routine decisions to follow through to turn your plans into reality. That’s why making decisions is the tool for improving your life. The rest of your life just happens beyond your control.

We all learned to make decisions by trial and error as very few individuals have had any education or training about how to make good decisions. Hence, we each have our own decision-making style composed of habits. Over the last four decades, researchers and scientists in the fields of behavioral economics and psychology have identified numerous biases and shortcomings of the habits used by all decision-makers. A concise summary of these findings is that decisions are often not adequately understood when a choice is made, and the choice of an alternative strongly depends on how the alternatives are presented rather than on their potential impacts.

My new book, Give Yourself a Nudge presents numerous ways for you to limit the influence of the biases and shortcomings of your natural decision-making habits. It describes and illustrates several different types of personal nudges that guide you to make smarter decisions. These nudges help you clearly define the decision that you face, thoroughly articulate what you want to achieve by making that decision, create better alternatives to consider, and deliberately identify more desirable decisions to face. Personal nudges are applicable to all of your decisions.

My favorite personal nudge concept is called a decision opportunity. To understand this important concept, ask yourself “Who should be making your decisions?” Obviously, you should. So who should be making the decisions about which decisions you should face? This is a more challenging question. My response is that you should be making more of them than you currently are.

You do not choose the decision problems that occur due to the actions of others and circumstances beyond your control, and you must reactively address these decisions. However, you can proactively identify any specific decision that you want to face. I refer to these decisions as decision opportunities.

Pursuing a decision opportunity usually improves your life, whereas solving a decision problem rarely can improve your life. Let me explain. Most decision problems result from something that becomes worse in your life: you become sick, your car is damaged, or you lose your job. Solving such a decision attempts to restore your quality of life to its level before the decision problem occurred. When you create a decision opportunity, nothing in your life becomes worse. Pursuing a decision opportunity should improve circumstances which raises your quality of life.

To create a decision opportunity, all that you initially need to do is think about something you would really like to have or experience for yourself or others. You then define the decision opportunity as ’decide how to make that desired future a reality’. There are no limits to thoughts, so anything you envision can be the basis for a decision opportunity. After you define a decision opportunity, then address it in the same way that you do for a decision problem. Specifically, clarify all of your objectives for that decision opportunity, next create a set of potential alternatives to achieve them, and then select the alternative that best achieves your objectives.

The only reason to make any decision is to achieve something. That something is made clear by identifying the objectives for the decision, which should then guide all effort on that decision. Fully identifying all the objectives for an important policy decision is difficult and often not done. At IIASA, I developed techniques to help stakeholders articulate their objectives, which stimulates the creation of a richer set of alternatives and provides a basis for a more impactful analysis of those alternatives. Fully identifying all of the objectives for any IIASA project today is just as critical as it was in the past.

The Cercedilla Manifesto: Advocating for more environmentally and socially sustainable research meetings

By Raquel Guimaraes, postdoc in the IIASA World Population Program, and Debbora Leip, an alumnus of the IIASA Advanced Systems Analysis Program

IIASA researcher Raquel Guimaraes and former research assistant Debbora Leip encourage the support of the Cercedilla Manifesto, arguing that it is high time for the scientific community to take responsibility and set an example by making research meetings more sustainable.

The research community widely agrees that strong action is needed to counteract the climate crisis that is currently taking place. Nevertheless, scientists regularly meet at conferences that are often far from sustainable. Problems range from participants flying to attend events, to unnecessary gadgets and gifts handed out at the meetings, and unsustainable catering at conference dinners. In light of the current public debate on environmental and social sustainability, we call on scientists to take a leading role in changing their work practices towards more sustainable habits, starting with research meetings.

In April 2020, Alberto Sanz-Cobena and several colleagues published an article titled Research meetings must be more sustainable in Nature Foods. They presented the Cercedilla Manifesto with 12 sustainability decisions as guidelines for organizers and attendees of research meetings (see Figure 1). The starting point of the manifesto is to question whether a physical meeting is indeed necessary. If organizers decide that it is, there is still the question of whether each single attendee really needs to physically join the conference. Often, remote participation can be equally efficient if a technical solution is provided by the organizers. Furthermore, if a decision to conduct a physical meeting is taken, organizers have to consider what food will be served.

The authors state that excessive amounts of food and food waste are very common at meetings, which makes a change of mindset towards better food management very important, not only for climate change, but for many other environmental threats. In our opinion, this point has so far been neglected in public debate.

Figure 1: Twelve points to enhance the sustainability of research meetings as proposed by the Cercedilla Manifesto (Sanz-Cobena et al., 2020), which is based on a co-creative approach to the production, provision, and consumption of food and services at scientific meetings, and is inspired by Sustainable Development Goal 12 (See also: https://www.openpetition.eu/petition/online/cercedilla-manifesto-research-meetings-must-be-more-sustainable)

Given the urgency for climate change action and the need for individuals to play an active role – with research scientists taking the lead – we assert that it is urgent to start changing our habits and setting an example regarding environmental and social sustainability in research meetings. Indeed, many of us take it for granted that to meet and discuss our work, we must travel. Most attendees do not even question that unnecessary gadgets and gifts are distributed or that opulent dinners are provided.

We hope that the Cercedilla Manifesto will raise awareness about the fact that good scientific output often does not require a physical meeting by providing a conceptual framework for change in this regard. If we support the manifesto, we stand a chance to lower the barrier to dare deviating from currently applied practices. The 12-sustainability decisions were designed by specialists to serve as a reference for anybody who wishes to organize/attend a sustainable meeting.

In the current situation brought about by the global COVID-19 crisis, almost everybody has experienced that remote conferences are not only possible, but also efficient – sometimes even more so than a physical meeting would have been. First, it saves time in terms of travel. Second, it may be more inclusive by allowing people to attend, who would not have had the opportunity to join otherwise, be it for financial, family, or other reasons. In addition, remote meetings provide additional features, like a chat function that could add another discussion layer.

Of course, remote meetings also have their limitations: informal in-person meetings during coffee breaks, for example, can enhance networking and free discussions, and sometimes contribute significantly to a meeting’s outcome. Virtual meetings also face several other challenges, such as participation by attendees from different time zones, or poor internet connections. These issues could however easily be addressed by spreading the meeting over more days, in such a way that the need for attendance outside of acceptable time slots is minimized, and by investing saved traveling costs into better equipment.

Let us learn from this experience and not go ‘back to normal’ after the COVID-19 crisis. We should take this as an opportunity to speed up change and tackle the other global crisis of climate change!

IIASA, East and West Germany, and the Cold War: Researching IIASA’s History

By Liza Soutschek, doctoral researcher at the Leibniz Institute for Contemporary History, Germany

Liza Soutschek shares her journey in researching the institute’s history relating to the Cold War for her PhD dissertation.

IIASA, Schloss Laxenburg, November 1975

Howard Raiffa, the founding director of IIASA, was about to leave Schloss Laxenburg in November 1975 to return to the USA. In his farewell address, he reflected on the institute’s first three years as an East-West research institute during the Cold War and concluded:

“My most exhilarating moments at IIASA, the times when I feel most rewarded by all our efforts, occur whenever I am present at a scientific meeting and scientists from different disciplines and cultural backgrounds argue with each other, on substantive issues, without being conscious of their roles as mathematicians or economists or management scientists or of their national identities. I will never forget those times, when [Wolf] Haefele of F.R.G. [West Germany] and [Hans] Knop of G.D.R. [East Germany] would argue heatedly on a scientific point – sometimes on the same side and at other times on opposite sides.”

As Howard Raiffa pointed out, IIASA, founded in 1972 in the wake of Cold War détente, provided an exceptional platform for scientific dialogue and exchange across borders – in particular for East and West Germans.

Intrigued by IIASA’s history

Looking back from the present day, knowing how difficult interdisciplinary collaboration between scientists from different nations and cultures can be, one question that comes up right away is: what was it like working at IIASA in the 1970s and 1980s in the context of the Cold War?

I asked myself this question when I first came across IIASA in the fall of 2017, and the spring of 2018, when I started working on a dissertation project on the institute’s East and West German history. It is done as part of a research group that examined “Cooperation and Competition in the Sciences” in case studies from a historical perspective. In my dissertation, I analyzed the relations between scientific and political actors from East and West Germany in the context of IIASA, with a focus on mechanisms of collaboration and competition at the local site as well as on wider effects in the entangled Cold War German history.

Historical research: books, dust, and coffee

Historians write books, but in order to do that we have to read hundreds of other books, look for traces in (sometimes more, sometimes less) dusty archives, and drink a lot of coffee with interesting people.

Initially my research led me to several German state and scientific archives. In the Federal Archives, for example, I found evidence of close interconnections between German science and politics during the Cold War regarding IIASA – not only in the case of the GDR, but also the FRG. Besides the intention to build a bridge between East and West, IIASA was also an arena for Cold War rivalry in the eyes of both German states. My favorite archival find were the documents of  the Max Plank Society, which was the former West German National Member Organization of IIASA.

In Germany, I also had the opportunity to talk to former West German members of the IIASA energy group in the 1970s and 1980s. Among them was Rudolf Avenhaus, who started working in the energy project under the leadership of Wolf Häfele in the summer of 1973. Over several cups of coffee, he told me about his life, what it was like to work at IIASA in those years, and about his collaboration with Willi Hätscher, one of the few East Germans in the group at that time.

A visit to IIASA and an inquiry

I finally had the chance to visit IIASA in the summer of 2019. With the help of several IIASA colleagues, I explored the IIASA archive for insights into the institute’s East-West German history. I also had the opportunity to discover more by talking to former and current IIASA employees. Two conversations I want to mention in particular, were with long-term staff members Martha Wohlwendt and Ruth Steiner, who provided an alternative view of IIASA to that of the scientists. I enjoyed my visit to the beautiful Schloss Laxenburg immensely and hope to return.

After collecting all these sources, from archival records to personal interviews, I can now begin writing an account on how cooperation and competition formed the relations between East and West Germans in the context of IIASA and thus, make IIASA’s history even better known.

After sharing this insight into my research, I would like to end with an inquiry. If you read this and think, “I could add something to this story!”, I would be happy to hear from you. Whether you are a former German IIASA staff member or have another connection to all of this, maybe we can add another piece to the puzzle together.

Creating a safe space to talk about gender equality in science

By Luiza Toledo, Science Communication Fellow 2019

Luiza Toledo writes about how the IIASA Women in Science Club are creating a safe space to talk about and advance gender equality in science.

Sustainable Development Goal (SDG) 5 is to achieve gender equality and empower all women and girls. A recent report titled, Harnessing the power of data for gender equality produced by Equal Measures 2030, however, shows that we still have a long way to go before this goal becomes a reality.

Countries in Europe and North America, along with two in the Asia-Pacific region (Australia and New Zealand), achieved the highest scores in terms of gender equality on the 2019 SDG Gender Index. However, even in the 20 top scoring countries, there are still indicators that score low. This suggests that even the countries with high overall scores for gender equality are struggling with thorny issues – one of them being women in science and technology research positions.

As an international institute, IIASA was founded on the principles of equal opportunity, which naturally includes equality in terms of gender balance. The institute’s 2018 Annual Report shows that the number of early-career female IIASA scientists has steadily been growing over the last few years. Since 2016, the number of female researchers increased by 24%, with most of the new hires joining as research assistants. Despite this increasing trend, the gap for PhD level researchers is as high as it has ever been with men outnumbering women four to one. In addition, there is a lack of female scientists in the over-40 age group, which is by no means unique to IIASA. Researchers who study gender and science have even compared women’s careers in science with a leaky pipeline – a flawed channel system that loses quantity before it reaches the destination.

Even though it is unrealistic to expect a 100% retention of women in science related careers (or any career for that matter), male researchers still have a much higher retention rate in scientific careers than their female colleagues do, and this is where the problem lies. According to the IIASA Diversity and Work Environment Report from 2015, male researchers at IIASA on average stay with the institute for seven years, whereas female researchers stay for only four years. To overcome the leaky pipeline effect, we should start creating a workplace culture that aims to recruit and retain women and is more open to discussing and tackling gender issues in academia, thereby developing a safe networking space.

The Women in Science Club (WISC) at IIASA is a great example of a safe networking space that embraces gender equality and shows the power of women that support other women. Co-led led by Amanda Palazzo, a researcher in the institute’s Ecosystems Services and Management Program, and IIASA Network and Alumni Officer Monika Bauer, the club has a self-proclaimed mission to build a network where women connected to science can share experiences, empower themselves, and highlight the work of other women connected to science.

The idea of creating a network of women in science came about in the fall of 2016 when former Finnish President, Tarja Halonen, visited IIASA. During her visit, she asked to meet with the women of IIASA to talk about diversity and equity issues. This conversation was the first of several meetings that are now attended by women (and men) across the institute under the auspices of WISC.

“The conversation was inspiring and after that first meeting, a few of us thought about organizing a club to continue working on the issues that came up from our discussion with President Halonen,” explains Palazzo.

Nowadays, the WISC organizers arrange lunchtime meetings known as “Meet, greet, and eat” sessions to coincide with visits to IIASA by prominent researchers and other professionals from IIASA and elsewhere who want to share their experiences.

“I’ve found that more experienced and senior women who may have been the only women in their departments at the start of their careers or may have had to fight for a seat at the table are often the quickest to agree to meet with WISC. This shows me that they see the value in a club like ours,” Palazzo adds.

Although the number of women now engaged in science is the highest it has ever been, there are still too few women in positions of leadership. According to Palazzo, at IIASA, this situation is set to change with the institute’s newly appointed Deputy Director General for Science who joined IIASA in November this year.

“I’m excited that Leena Srivastava has joined us and I hope that this is just the start of many changes at IIASA that will bring more women into positions of leadership,” she says.

Palazzo says that the most valuable thing that she has learned so far is that no two women have the same story or path to success.

“I found it reassuring to hear successful women tell us that when they were starting out or even several years into their careers they also didn’t know exactly what contribution they wanted to make. They were learning as they went along. It has also been useful to hear women talk about building resilience to negative comments or behaviors and recognize that these behaviors reflect the other person’s fear and insecurity. In the end, the Women in Science Club is a place to share, contribute, listen, and learn. We want women connected to science to feel that they are a member of our community, that they have a seat at our table, and that they belong here,” she concludes.
