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.
By Michel Spiro, President of the International Union of Pure and Applied Physics (IUPAP) and President of the Steering Committee for the proclamation of the International Year of Basic Sciences for Sustainable Development in 2022 (IYBSSD 2022)
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.

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.”
By Xu Wang, IIASA Young Scientists Summer Program (YSSP) alumnus and Assistant Professor at Beijing University of Technology and Pallav Purohit, researcher in the IIASA Air Quality and Greenhouse Gases Program.
Xu Wang and Pallav Purohit write about their recent study in which they found that accelerating the transition to climate-friendly and energy-efficient air conditioning in the Chinese residential building sector could expedite building a low-carbon society in China.
China saw the fastest growth worldwide in energy demand for space cooling in buildings over the last two decades, increasing at 13% per year since 2000 and reaching nearly 400 terawatt-hours (TWh) of electricity consumption in 2017. This growth was largely driven by increasing income and growing demand for thermal comfort. As a result, space cooling accounted for more than 10% of total electricity growth in China since 2010 and around 16% of peak electricity load in 2017. That share can reach as much as 50% of peak electricity demand on extremely hot days, as seen in recent summers. Cooling-related carbon dioxide (CO2) emissions from electricity consumption consequently increased fivefold between 2000 and 2017, given the strong reliance on coal-fired power generation in China .
In our recent publication in the journal Environmental Science and Technology, we used a bottom-up modeling approach to predict the penetration rate of room air conditioners in the residential building sector of China at the provincial level, taking urban-rural heterogeneity into account. Our results reveal that increasing income, growing demand for thermal comfort, and warmer climatic conditions, could drive an increase in the stock of room air conditioners in China from 568 million units in 2015 to 997 million units in 2030, and 1.1 billion units in 2050. In urban China, room air conditioner ownership per 100 households is expected to increase from 114 units in 2015 to 219 units in 2030, and 225 units in 2050, with slow growth after 2040 due to the saturation of room air conditioners in the country’s urban households. Ownership of room air conditioners per 100 households in rural China could increase from 48 units in 2015 to 147 units in 2030 and 208 units in 2050 .
The Kigali Amendment to the Montreal Protocol on Substances that Deplete the Ozone Layer will help protect the climate by phasing down high global warming potential (GWP) hydrofluorocarbons (HFCs), which are commonly used as refrigerants in cooling technologies . Promoting energy efficiency of cooling technologies together with HFC phase-down under the amendment can significantly increase those climate co-benefits. It is in this context that we assessed the co-benefits associated with enhanced energy efficiency improvement of room air conditioners (e.g., using efficient compressors, heat exchangers, valves, etc.) and the adoption of low-GWP refrigerants in air conditioning systems. The annual electricity saving from switching to more efficient room air conditioners using low-GWP refrigerants is estimated at almost 1000 TWh in 2050 when taking account of the full technical energy efficiency potential. This is equivalent to approximately 4% of the expected total energy consumption in the Chinese building sector in 2050, or the avoidance of 284 new coal-fired power plants of 500 MW each.
Our results indicate that the cumulative greenhouse gas mitigation associated with both the electricity savings and the substitution of high-GWP refrigerants makes up 2.6% of total business-as-usual CO2 equivalent emissions in China over the period 2020 to 2050. Therefore, the transition towards the uptake of low-GWP refrigerants is as vital as the energy efficiency improvement of new room air conditioners, which can help and accelerate the ultimate objective of building a low-carbon society in China. The findings further show that reduced electricity consumption could mean lower air pollution emissions in the power sector, estimated at about 8.8% for sulfur dioxide (SO2), 9.4% for nitrogen oxides (NOx), and 9% for fine particulate matter (PM2.5) emissions by 2050 compared with a pre-Kigali baseline.
China can deliver significant energy savings and associated reductions in greenhouse gas and air pollution emissions in the building sector by developing and implementing a comprehensive national policy framework, including legislation and regulation, information programs, and incentives for industry. Energy efficiency and refrigerant standards for room air conditioning systems should be an integral part of such a framework. Training and awareness raising can also ensure proper installation, operation, and maintenance of air conditioning equipment and systems, and mandatory good practice with leakage control of the refrigerant during the use and end-of-life recovery. Improved data collection, research, and cooperation with manufacturers can equally help to identify emerging trends, technology needs, and energy efficiency opportunities that enable sustainable cooling.

By Rachel Potter, Communications Officer in the IIASA Communications and External Relations Department.
Several members of the IIASA Strategic Taskforce share their views on the bold new IIASA strategic agenda, how it came to be, and what it promises for the future.
What will the world look like in 2030 and beyond? We are living in extraordinary times and our rapidly transforming planet faces multiple global sustainability challenges, threats, and opportunities. How will research institutes like IIASA continue to make meaningful contributions to address these complex issues?
This is precisely what IIASA has been exploring over the past 18 months while formulating its strategic direction for the next 10 years. Through institute-wide consultations, a strategic taskforce was entrusted with coordinating the process that led to “Reducing footprints, enhancing resilience” – the institute’s ambitious new strategy for 2021-2030 that positions IIASA as the primary destination for integrated systems solutions and policy insights.
A bottom-up inclusive approach
The strategy consultation process was very different to those previously undertaken at IIASA. Acting Transitions to New Technologies Program Director and Energy Program researcher, Shonali Pachauri describes the rationale behind the process:
“While in the past strategic planning had largely been driven by the directorate and program directors, this time, mid-career scientists were to drive the process forward. It was not meant to be one researcher from each program on the taskforce, but it ended up being something like that, so we had a broad representation of disciplines from across the institute. The taskforce was responsible for developing the scientific content of the plan and we did this in an inclusive manner with input from staff through workshops, an online platform, and both informal and formal meetings.”
Reflecting our changing world
The UN Sustainable Development Goals (SDGs) established in 2015, are clearly reflected in the new strategy. Linda See, a researcher in the Ecosystems Services and Management Program, explains:
“We have always worked on sustainable development and transformations but this is now more of a focus compared to the previous strategy. The emphasis is on using our expertise as systems scientists to explore the interrelationships between different SDGs and how there can be synergies and trade-offs in different scenarios to achieve them.”
“Another key shift is that the new strategic plan takes a human-centered approach, placing more emphasis on how people are a core component of pathways towards sustainability and resilient societies,” adds World Population Program Deputy Program Director, Raya Muttarak.
Fellow taskforce member and Acting Water Program Director, Yoshihide Wada, agrees:
“This focus on social science, governance, and human behavior came out of our consultations with staff. IIASA researchers really want to go in this direction. People increasingly understand that with the climate and environmental goals in particular, it can’t only be technology and bioeconomy, it has to be about lifestyles as well, which means we need to strengthen our ability to analyze behavior and identify which levers to pull to encourage lifestyle changes.”
“There is also a stronger focus on biodiversity. The importance of this was borne out of the current COVID-19 crisis. Looking at the origin of the virus and how the pandemic has been aided by the loss of biodiversity – it’s evident that this is crucial,” adds Manager of Library and Knowledge Resources, Michaela Rossini.
Building on strong foundations for continued innovation
Taskforce members agree that the new strategy consolidates the unique strengths of IIASA while providing the space and flexibility for innovation.
“IIASA is unique not only because of our excellence in the fields of energy, environment, climate change, and ecosystems services but also because we have strong, empirically-based analyses and studies from social sciences, which can quantify and forecast relevant demographic, social, and economic dimensions in systems analysis,” says Muttarak.
“I think the new strategy pushes the interdisciplinarity at IIASA even further. The new program structure is very integrated. This is vital to facing today’s sustainability challenges. There are big aspirations in the strategy and it’s our responsibility to translate this into practice. As scientists, we have to be open to change and include elements that we may never have thought of. It makes things very interesting. It makes innovation happen,” Wada adds.
Pachauri explains that IIASA was created as a science-to-policy interface in 1972 and its purpose has always been to bridge divides: both between disciplines and across transnational boundaries. The new strategy really builds on this history. While the institute innovates a lot in terms of models and methods, this always happens through an applied lens of doing something that will ultimately feed into policy.
One of the institute’s key strengths is its relationships with its National Member Organizations and strong global network. These relationships are what make it possible to tackle the real-world problems society faces today. The flexibility to work across networks, countries, and different levels of government is strongly emphasized in the strategy.
A bit like family
According to Muttarak, the process of drawing up the new IIASA strategy has been a great opportunity to work with people from different programs and units. Not only has this allowed everyone involved to get to know their colleagues better, but it has also enhanced team members’ understanding of systems analysis and the importance of IIASA.
“It was challenging and rewarding, a bit like family!” comments Pachauri. “There was a lovely dynamism in the team and although we had a Chair, everyone had a chance to lead at various times in the process.”
“As the only non-scientist I found working on the taskforce invaluable – understanding more about IIASA research and getting to know scientists from across the institute has really enhanced my awareness of what they do and what their needs are going forward,” Rossini concludes.
The full IIASA Strategic Taskforce is comprised of: Luis Gomez Echeverri, Matthias Jonas, Mauricio A. Lopes, Junko Mochizuki, Raya Muttarak, Shonali Pachauri, Michaela Rossini, Linda See, Thomas Schinko, Yoshihide Wada, and Fabian Wagner.
