In an attempt to foster economic development for Brazil, the government is planning to open up indigenous and protected areas for mining. But will this truly lead to economic development for the country? 2021 Young Scientists Summer Program (YSSP) participant, Sebastian Luckeneder is using spatial modeling to find out.
As the largest rainforest on the planet, the Amazon harbors the highest biodiversity of all ecosystems and is home to many indigenous tribes. It is also literally sitting on a goldmine of natural resources. There are plans in the works to open up protected and indigenous areas of the rainforest to mining activities, which is expected to bring more wealth and development for the country, but at the same time, it will also pose a threat to the environment and indigenous communities.
At first glance, the issue looks like the classic trade-off between economic growth versus environmental and social disruption. In reality however, mining affects social, environmental, and economic spheres both directly and indirectly, creating a complex network of interactions that potentially defy the current dogma.
Mining relies heavily on machines while creating relatively few jobs in comparison to the investment of capital it requires. In addition, mining companies are often large international corporations, which means that most of the profits gained from mining operations in a particular country end up outside that country’s borders.
“One could say that just the very few benefit from extractive activities, whereas many have to pay the cost,” says Sebastian Luckeneder, a 2021 YSSP participant at IIASA, when referring to the environmental destruction, disruption of livelihoods, and displacement of indigenous communities that mining would bring about.
As a second-year PhD candidate at the Institute for Ecological Economics of Vienna University of Economics and Business (WU), Luckeneder is studying the environmental and socioeconomic impacts of mining activities. At IIASA, he used spatial modeling to understand how mining and land use affect regional economic growth in Brazil in the hopes of finding the best economic solution for the country.
Using GDP growth as a proxy for economic development, he looked at the impacts of mining and other types of land use between 2000 and 2020. The model incorporates data on mining, agriculture, and land-use change, as well as other socioeconomic factors, such as employment and infrastructure for about 5,500 municipalities in Brazil.
The study is as complex as it sounds: Luckeneder’s main challenge is to set up a theoretical framework that depicts how the environmental and socioeconomic factors influence each other. Once his comprehensive model is complete, he hopes to get a clear picture of how mining affects the Brazilian economy.
He suspects that while mining activities would bring some economic gains, these might not be sustainable, as the environmental and social upheaval that follow the opening of a mine could negatively impact development in the long-run.
While economic development is important, in the current climate crisis, decisions to enable activities that lead to deforestation cannot be taken lightly. Luckeneder hopes that his results will be used to inform the political debate in Brazil and support policy decisions by the way of science.
Bringing together stakeholders from around the globe, the United Nations Food Systems Summit (UNFSS) calls attention to the opportunities, challenges, and promises that the transformation of our food systems can hold to advance sustainable development.
This transformation needs to happen, while the ongoing Covid-19 pandemic reminds us of the manifold vulnerabilities embedded in our food systems, the inter-dependence of our societies, and the entanglement of human and natural systems. The increases in weather and climate extremes that can clearly be attributed to climate change, ongoing biodiversity loss, environmental degradation, and pollution further illustrate that food systems need to manage a broad range of compounding risks and pressures that play out over different spatial and temporal scales. Advancing and securing gains towards the Sustainable Development Goals (SDGs) will not only require meeting multiple economic, social, and environmental objectives, but also demand pathways that ensure a safe navigation through a treacherous and shifting risk landscape. But how do we build resilience into the food system while transforming it at the same time?
Great strides have been made in technologies and practices that can help food systems manage existing and emerging risks. For example, on the production side, timely access to seasonal forecasts and early warning information coupled with extension services can help farmers to make the right decisions for planting and to anticipate, adapt, and cope with possible shocks. Precision agriculture, which harnesses advances in technology to ensure optimal health and productivity of crops and soils, can reduce the need for inputs. Diversification of livestock and agricultural traits can help farmers to reduce production risks in marginal environmental conditions.
Minimizing the spillover risk of zoonotic diseases, mitigating, and adapting to climatic and environmental changes place additional demands on food systems, but also offer new opportunities. Living sustainably requires comprehensively managing land use, enabling for food production, but maintaining and recovering critical ecosystem goods and services, such as carbon and biodiversity. It requires advancing nature-based solutions, where nature is seen as an ally and not an adversary in delivering on development objectives. Strengthening natural capital accounting and incentivizing environmental stewardship by rewarding actors in the food system for efficient and sustainable management of natural resources, and appropriately informing consumer choices will be important ingredients in reducing the environmental impact as well as environmental vulnerabilities of food systems.
The transformation of the food system is an ongoing process. It is therefore important to understand the impact of different changes across the system. Shifts to healthier diets can have important co-benefits in reducing pressure on the environment and natural resources. Such transformation implies, however, that shifts in demand are also matched by shifts in supply, reflecting appropriate adjustments of agricultural production. To accommodate such system shifts and facilitate system transitions over time, the social resilience and adaptive capacity of society must be addressed accordingly.
Food systems operate at different scales, ranging from local to global. Consequently, the role of trade in ensuring food security and human welfare across a range of contexts is critical. Several countries are already dependent on food imports. Trade can help the food security of regions where agricultural activities become less viable with progressive climate change. At the same time, the changing exposure to socioeconomic and environmental risks arising from the increasing inter-connectivity of societies and economies also need to be addressed, as illustrated by the current pandemic. The evolution of food systems has been largely shaped by a drive for efficiency. We must now consider carefully where efficiency needs to be (counter)balanced with an effort to promote greater diversity, and where we must build in greater redundancy to help manage the variety of risks facing food systems.
Forward-looking approaches aimed at transforming food systems towards greater resilience and sustainability will require a suite of measures within, as well as outside food systems. Such measures entail helping livelihoods and sectors to reduce their vulnerabilities and risk exposure, while also enabling the agility of food systems to manage future risks, avoiding lock-in of structures, which would become mal-adaptive over time. Achieving such transformation will depend on increased collaboration and trust building across sectors, enabling innovation in technologies and practice, strengthening of training and capacity development, and on the improvement of safety nets for reducing vulnerabilities to shocks and managing the social transition. Above and beyond, it requires re-calibrating the connection of food systems with other sectors and systems, such as health, environment, energy, and infrastructure.
The UNFSS in conjunction with the upcoming UN Climate Change Conference in Glasgow (UNFCCC COP26), and the UN Conference on Biological Diversity in Kunming (CBD COP15), are a formidable call to action for political leaders, decision makers in the public and private sectors, scientists, development practitioners, civil society, and to society at large, to come together and jointly imagine and build resilient and sustainable food systems that place people and nature at the center before it is too late.

North Korea is somewhat of an enigma and getting a glimpse into what transpires behind its borders is a difficult task. Based on our limited information, it however seems that its once luscious forests have disappeared at an alarming rate in the last few decades.
Deforestation in North Korea is fueled by economic difficulties, climate change, and a lack of information for effective forest management. As forests are recognized as important carbon sinks that are invaluable when working towards the climate goals established in the Paris Agreement, finding a way to restore them is imperative. Forests are also essential in solving food insecurity and energy issues, which is especially relevant in the face of the current economic hardship in North Korea.
Neighboring South Korea serves as a benchmark for a successful reforestation campaign after having restored most of its forest cover in the last half a century. South Korean researchers and NGOs are keen to support afforestation efforts in North Korea and it seems that the North Korean government is also prioritizing this through a 10-year plan announced by North Korean leader Kim Jong-Un in 2015. The strained relationship between the two Koreas however, often hinders effective collaboration.
‘’We are close to North Korea regionally, but direct connection is difficult for political reasons. However, many researchers are interested in studying North Korea and there are currently many projects for South and North Korea collaboration supported by the Ministry of Unification,” says Eunbeen Park, a participant in the 2021 Young Scientists Summer Program and a second year PhD student in Environmental Planning and Landscape Architecture at Korea University in Seoul, South Korea.
Park specializes in using remote sensing data for environmental monitoring and detecting changes in land cover. During her time at IIASA, she will use the Agriculture, Forestry, and Ecosystem Services Land Modeling System (AFE-LMS) developed by IIASA to support forest restoration in North Korea.
First, Park will use land cover maps dating back to the 1980s to map the change in forest cover. She will then identify areas for potential afforestation considering land cover change, forest productivity, climate, and different environmental variables, such as soil type. She will also develop different afforestation scenarios based on forest management options and the tree species used.
According to Andrey Krasovskiy, Park’s supervisor at IIASA, when selecting tree species for afforestation we need to take into account their economic, environmental, and recreational values.
“From a set of around 10 species we need to choose those that would be the most suitable in terms of resilience to climate change and to disturbances such as fire and beetles,” he says.
Challenges in data collection
A major challenge in Park’s research is obtaining accurate information for building her models. If there is relevant research from North Korea, it is not available to foreign researchers and without being able to enter the country to collect field data in person, her research has to rely on remote sensing data or data extrapolated from South Korean studies.
Fortunately, in recent years, remote sensing technology has evolved to provide high-resolution satellite data through which we are able to take a thorough look at the land cover of the elusive country. Park will match these maps with yield tables provided by Korea University based on South Korean data. As the ecology of the two Koreas are largely similar, these maps are thought to provide accurate results.
Is there space for science diplomacy?
“Research shouldn’t have any boundaries,” notes Krasovskiy. “In reality however, the lack of scientific collaboration between research groups in South and North Korea poses a major obstacle in turning this research into policy. Luckily, some organizations, such as the Hanns Seidel Foundation in South Korea, are able to bridge the gap and organize joint activities that provide hope for a more collaborative future.”
Despite the diplomatic hurdles, Park hopes that her work will find its way to North Korean policymakers.
“I expect my research might make a contribution to help policymakers and scientific officials establish forest relevant action in North Korea,” she concludes.

A consortium of international scientific unions and scientific organizations’ plans to declare 2022 the International Year of Basic Sciences for Sustainable Development are underway. Michael Spiro makes the case for why the world needs this now more than at any time in the past.
For almost a year and a half now, the world has been disrupted by the COVID-19 pandemic caused by the SARS-CoV-2 virus. But how much worse could the situation have been without the progress and results produced for decades, even centuries, by curiosity-driven scientific research?
We deplore the many deaths due to COVID-19, and the future is still very uncertain, especially with the detection of new variants, some of which are spreading more quickly. But how could we have known that the infection was caused by a virus, what this virus looks like and what its genetic sequence and variations are without basic research?
Viruses were discovered at the beginning of the 20th century, thanks to the work of Frederick Twort, Félix d’Hérelle, and many others. The first electron microscope was built in the 1930s by Ernst Ruska and Max Knoll; and DNA sequencing began in the mid-1970s, notably with research by the groups of Frederick Sanger and Walter Gilbert.
Such a list could of course go on and on, with basic research at the root of countless tests, treatments, vaccines, and epidemiological modeling exercises. We even owe high-speed, long-distance communications, which allow us to coordinate the fight against the pandemic and reduce interruptions in education, economic activities, and even the practice of science, to the discovery and study of electromagnetic waves and optic fibers during the 19th century, and the development of algorithms and computers codes during the 20th century. The COVID-19 pandemic is a reminder (so harsh and brutal that we would have preferred to have been spared) of how much we rely on the continuous development of basic sciences for a balanced, sustainable, and inclusive development of the planet.
On many other issues, basic sciences have an important contribution to make to progress towards a sustainable world for all, as outlined in Agenda 2030 and its 17 Sustainable Development Goals, adopted in September 2015 by the United Nations General Assembly. They provide the essential means to address major challenges such as universal access to food, energy, and sanitation. They enable us to understand the impacts of the nearly eight billion people currently living on the planet, on the climate, life on Earth, and on aquatic environments, and to act to limit and reduce these impacts.
Indeed, unlike our use of natural resources, the development of the basic sciences is sustainable par excellence. From generation to generation, it builds up a reservoir of knowledge that subsequent generations can use to apply to the problems they will face, which we may not even know about today.
The International Year of Basic Sciences for Sustainable Development (IYBSSD) will focus on these links between basic sciences and the Sustainable Development Goals. It is proposed to be organized in 2022 by a consortium of international scientific unions and scientific organizations* led by the International Union of Pure and Applied Physics (IIUPAP) with the recommendation of a resolution voted by the UNESCO General Conference during its 40th session in 2019. Over 50 national and international science academies and learned societies and around 30 Nobel Prize laureates and Fields Medalists also support this initiative. The Dominican Republic has agreed to propose a resolution for the promulgation of the IYBSSD during the 76th session of the United Nations General Assembly, beginning in September 2021.
We very much hope that scientists, and all people interested in basic science, will mobilize around the planet and take this opportunity to convince all stakeholders – the general public, teachers, company managers, and policymakers – that through a basic understanding of nature, inclusive (especially by empowering more women) and collaborative well-informed actions will be more effective for the global common interest. As IIASA is one of the consortium’s founding partners, we especially invite all IIASA scientists, alumni, and colleagues they are collaborating with to create or join national IYBSSD 2022 committees to organize events and activities during this international year.
More information, as well as communication material, can be found at www.iybssd2022.org. This will also be shared through social media accounts (look for @iybssd2022 on Facebook, Twitter, LinkedIn and Instagram). You are also invited to subscribe to the Newsletter here.

The IIASA-ISC Rethinking Energy Solutions Report identifies the negative and positive lessons learnt from the ongoing COVID-19 pandemic in relation to energy consumption and demand, and recommends several immediate actions.

As a result of the pandemic’s confinement and containment policies, energy demand and resulting energy-related carbon emissions declined by an estimated 2.4 billion tonnes in 2020 – a record drop according to researchers at Future Earth’s Global Carbon Project. However, the reduction is likely to be short-lived if structural changes do not occur.
The COVID-19 pandemic has caused foreseeable positive and negative disruptions to the global energy sector. This has revealed opportunities that can be learnt from to meet Sustainable Development Goals (SDGs) and the Paris Agreement pledges, with the positive disruptions showing us the possibility of a more sustainable and resilient future.
The IIASA-ISC Rethinking Energy Solutions Report recommends actions based on the opportunities and vulnerabilities in energy systems that the COVID-19 pandemic has brought to light.
“The pandemic is a threat, but also an opportunity, because it showed that the system we have spent a lot of money and resources on is not working the way it should, so the crisis should be used to draw up new budgets, take new actions, and rebuild society.”
– Behnam Zakeri, Research Scholar, IIASA
The report highlights that solutions previously thought to be out of reach are far more possible than expected. One such positive outcome is the digitalization of physical activities, such as attending work, schools, conferences, and other gatherings online. This has resulted in short-term lifestyle changes — introducing and normalizing digital solutions for a mass audience — which the report recommends capitalizing on in a post-COVID society.
Some companies, like Spotify, a music streaming service, have announced that they will let their employees work remotely from anywhere after the pandemic. The report suggests that more companies and governments should do the same, as digitalization offers opportunities to use resources more efficiently, and so has the potential to make consumption more sustainable and to reduce carbon footprints.
Efforts to digitalize and reduce the population’s carbon footprint work hand-in-hand with the need to reinvent urban spaces to reach the SDGs and combat climate change.
Cities consume 60-80% of global energy and produce more than 70% of carbon emissions. What’s more, 70% of the world’s population is projected to live in urban areas by 2050.
The report proposes that cities should be redesigned into more sustainable ‘urban villages’ so that they are optimized for energy efficiency. One way to do this would be to redesign cities into compact neighborhoods where all amenities (shops, offices, schools, etc.) are within walking distance. Paris, France, for example, promotes self-sufficient neighborhoods, with all the essential amenities placed within a 15-minute radius. Several other cities like Melbourne, Australia, with its “20-minute neighborhoods” and the Nordhavn “5-minute neighborhood” in Copenhagen, Denmark, are promoting this new standard for the use of space and sustainable mobility.
Another key approach to reinventing urban spaces is prioritizing nature-based solutions by using parks, green roofs, green walls, and blue infrastructure to combat climate change and connect the population back to nature. This also means centering public spaces around people, by converting street spaces from car use to sidewalks and bike lanes, and enhancing the quality and safety of walking and biking infrastructures.
The report also recommends that cities be rebuilt to incorporate renewable energy. The costs for renewable technologies are declining quite fast, but Zakeri explained that the problem with moving to renewable energy is not the cost but a lack of understanding. Consumers, experts, and governments lack the knowledge to distribute, access and install these technologies. However, in recent times, scientists and other experts have brought more awareness to them and are helping the trend move forward.
The report states the importance of developing net zero-energy communities that have a holistic approach to energy-efficient building renovation and construction of new buildings. The net zero-energy design must consider the energy interactions between individual buildings and the broader energy system on a local level.
These recommended actions aren’t just about energy efficiency but about creating a more fulfilling life for all.
“Rebuilding cities to be more sustainable and resilient [to future crises] not only has the potential to reduce energy consumption but also create a more joyful lifestyle that improves the wellbeing and experience of people living in a city.”
