What will the world be like in 2050?
Of course, it is difficult to make predictions, especially about the future, as the Danish proverb goes.
Part of the difficulty is that we – individuals and the institutions that allow us to act collectively and in the long term – routinely assume the future looks very much like the past. Just as routinely, though, this assumption is flipped on its head. Think of the global financial crisis, the Arab Spring, Brexit, or the recent US election.
But what if we already know what we want the world to look like in 2050. How do we get there?

I was reminded of the Danish proverb as I arrived at the International Institute for Applied Systems Analysis (IIASA) outside Vienna earlier this month for a three-day meeting of The World in 2050 (TWI2050) initiative. This was the third such scientific meeting hosted here at the home of some of the leading economic, demographic and energy modellers.
TWI2050 is arguably the most ambitious research being undertaken in the world today. At its heart is an ambition to map out the pathways for a sustainable planet. As with the previous meetings, it attracted about 130 complex-systems thinkers and computer-modelling experts.
Unlike other international modelling initiatives, TWI2050 was not created to explore a range of possible utopian to dystopian scenarios focusing on energy prices or climate change. The baseline assumption is a single scenario: successful completion of the Sustainable Development Goals (SDGs), agreed by all nations in 2015, and arriving in 2050 with a global economy operating within planetary boundaries – the limits of natural systems that keep Earth in a relatively stable state, relating to climate, biodiversity, deforestation, and fertilizer use, among others.
The 17 SDGs and their 169 targets are extremely ambitious. Buried in the detail are many trade-offs but also potential win-wins. Meeting the climate goal means reducing greenhouse-gas emissions to zero, and this could affect the energy, biodiversity, or consumption goals either positively or negatively. The goals and their inherent trade-offs are already catalyzing research and the results show how challenging this will be.
This month, scientists publishing in the journal Nature explored Australia’s land-use trade-offs to reach the goals. The team, who were not at the TWI2050 meeting, used a massive computer simulation called Land Use and Trade Offs (LUTO) to see how factors such as climate policies or crop prices could shape Australia’s landscape by 2050. Exploring 648 scenarios, researchers Brett Bryan and Lei Gao found just 1% of scenarios achieved five goals simultaneously. However, some goals seemed to go better together than others. Achieving targets related to food, water, and biofuel production was possible in 6.5% of scenarios, for example. The authors, whose work contributes to Future Earth’s Global Land Programme, conclude that national policymakers need more of this type of analysis to elucidate trade-offs and avoid conflicting policies. Moreover, they argued for more scientific coordination internationally for a global perspective on implementing the SDGs.
Other research groups have also begun exploring the world in 2050. Recently Karl Heinz Erb from the Institute of Social Ecology, Vienna, who attended the TWI2050 workshop, and colleagues explored 500 scenarios to assess options for feeding 9 billion people in 2050 without further deforestation .
Their work, which also supports the Global Land Programme, concluded that it was possible, but would likely mean low meat, vegetarian, or vegan diets globally. Meanwhile, Marco Springmann from the Oxford Martin Programme on the Future of Food, also attending, and colleagues showed that by 2050 a global vegetarian diet would reduce diet-related global mortality by 6-10% and food-related greenhouse gas emissions by 29-70% – contributing to several goals. This type of research is essential to understand potential win-wins but these examples do not provide the pathways to arrive at these scenarios.
So, are computer models powerful enough to capture essential elements of incremental and disruptive change across complex issues relating to poverty, equality, education, technology, policy, energy, food, water, and climate? Read more on the Rethink.earth website

Biogas–renewable fuel that can be produced from a variety of natural materials including manure, food waste, plant matter, and other organic matter–has the potential to solve a number of environmental challenges simultaneously: It can reduce the emissions of greenhouse gases such as methane (for example, from manure storage) and is the only mature type of renewable energy that can be directly used in electric power generation, heat generation, and transport sectors, and it leads to reduced impacts of pollution from waste disposal.

However, biogas is not without impacts of its own. The environmental benefit of using agricultural biogas in particular may be smaller than previously thought, because of the farming activities required for the production of suitable biogas feedstock (such as maize, wheat and triticale), which in turn generates local airborne pollution. Such factors are not adequately reflected in current energy measures.
In other words, existing policy instruments that have been adopted so far in Europe do not reflect the environmental impact associated with the production of certain biofuels because they do not account for other relevant environmental burdens generated along the supply chain.
This is especially the case for biogas, whose production contributes to several environmental burdens such as land use, traffic, and local emissions from the intensive use of fertilizers.
To overcome this issue, my colleagues and I have proposed the adoption of a monetization procedure through which the so-called external costs are incorporated in energy wholesale prices. This method, allows to allocate a cost to the environmental damage associated with emissions of a wide range of pollutants, which can be consequently incorporated in any economic optimization model.

In a new study, which I conducted with Sylvain Leduc and Florian Kraxner, we took a look at the biogas situation in my home country, Italy. We incorporated the total internal and external costs of different biogas utilization pathways in the BeWhere model—a model used for optimizing renewable energy systems–and compared with the performance of the current Italian energy mix.
We found out that, although each type of biogas leads to reduced CO2 emissions compared to fossil fuels, such environmental benefits are sharply reduced when we take other pollutant emissions into account. .
In particular, farming activities generate high non-carbon emissions such as nitrogen oxides (NOx), sulfur dioxide, and particles. Most of this pollution comes from chemical fertilizers and diesel combustion in farming activities–and these emissions corresponding to almost 6% of the energy content of the raw biogas produced.
The second cause of external costs is transportation of the biomass, which mainly produces local emissions of NOx. Local concerns about this issue, are a main source of opposition to new plants, and based on our study, these concerns appear reasonable.
Our results suggest that carbon emission mitigation alone is not always a satisfactory measure to evaluate the sustainability of biogas technologies in order to define energy policies. Other environmental burdens need to be considered when we discuss the environmental sustainability of energy production processes.

A transition to new energy sources—whether renewable, nuclear, or shale—does not just depend on technical availability and economic feasibility. In order for new projects to succeed, human factors, such as public and social acceptance, and willingness to use technology or to pay for it, are essential but often overlooked. It is important to understand these factors, because differences in views and perceptions of technology risks, benefits, and costs might lead to conflicts that could threaten the success of new projects.
Conflicts often appear between two or more parties with incompatible goals, different interests, or different risk perceptions, which can develop into either cooperation or conflict. For example, public opposition can lead to cancellation or delay of a planned project, and differences in views and risk perceptions can result in conflicts among different stakeholder groups. At the same time, if policymakers take into account this heterogeneity of views, the knowledge on the ground can lead to a better implementation of energy projects with more benefits for society and a smaller impact on the environment and hosting communities.

An energy transition is currently taking place in the Middle East and North Africa. The region faces a number of challenges such as rising energy demand, unstable energy imports, increasing pressure on environmental resources, expectations of socioeconomic development, and political transformation. Morocco, Jordan, Tunisia, and other countries in the region are discussing new electricity infrastructure. Although large-scale deployment of renewable energy sources receives political support in this discussion, fossil fuels, and new emerging technologies such as shale oil and nuclear power are two prominent alternatives in the countries’ national development plans.
For this energy transition to succeed, policymakers in the region must adopt an adaptive and inclusive governance approach, which addresses possible risks, benefits, challenges, and socio-ecological shifts. In order to find compromise solutions, this approach should be based on an understanding of the positions of each stakeholder group involved in the project planning and affected by its implementation.
To understand these potential conflicts, a group of IIASA Risk and Resilience Program researchers, including myself, Jenan Irshaid, Love Ekenberg and Joanne Bayer, are conducting a series of six stakeholder workshops in Jordan. Each of the workshops targets different stakeholder groups such as local communities, NGOs, financial institutions, project developers, private companies, academia, young leaders, and national policymakers, including ministries of public works, of water and irrigation, energy and mineral resources, and municipal affairs. The goal of these workshops is to understand how different groups of stakeholders see risks and benefits of different electricity generation technologies, including renewables, fossil fuels, and nuclear, as well as views and visions of different stakeholders of Jordan in 2040 in terms of the social, environmental, and economic situation.
In our research we go beyond the existing discussion on social acceptance as a proxy of a Not-in-My-Back-Yard (NIMBY) attitude. NIMBY is often a misleading concept to understand local objections, because it is frequently understood as some kind of “social gap” between the need of policy intervention, settled at the national level, and the hostility towards its deployment at the local level. The NIMBY concept often includes skepticism of different stakeholder groups towards positions of the others. Also the term “acceptance” towards technology or infrastructure innovation often means a passive position towards something that cannot be changed. In contrary, willingness to use technology or to participate financially means a more active position.
In recent research, we discuss the usefulness of a model that we call “decide-announce-defend” (DAD), and try to understand how integration of various views and risk perceptions can lead to enhanced legitimacy of decision-making processes and trust. To understand the trade-offs between benefits of national energy goals and conflict sensitivity, we evaluated each electricity generation technology that could be relevant for Jordan against a set of criteria, including domestic value chain integration, use of domestic resources, technology and knowledge transfer, global warming potential, electricity system costs, job creation processes, pressure on land and water resources as well as safety, air pollution and non-emission waste.

Recently, Indonesia has been combating its most severe forest fire of the decade. Around 43 million Indonesians have been exposed to hazardous fumes, and countless loss of biodiversity and ecosystem services has occurred. An estimated 1 billion tonnes of carbon emission has been released to the atmosphere. Within three months, Indonesia’s daily carbon emission has surpassed the average daily emissions of the whole US economy.

Forest fires in Indonesia are closely related to unsustainable agricultural practices spreading out throughout the country. Indonesia is the world’s largest producer of palm oil, with 8 million hectares of plantation area. Other than its significant contribution to the economy, and broadly debated effects on the environment, oil palm is also regarded as a promising solution to the country’s effort to achieve energy security. The current administration has set ambitious targets to increase national biofuel production, and to consume it domestically.
In this landscape of uncertainty and crisis, scientific support for Indonesian energy policy is more urgently needed than ever. That’s why it is one of our main focuses in the IIASA Tropical Forests Initiative (TFI).
“Scientific authority has to be the basis of our future energy policies,” said Mr. Sudirman Said, Indonesia’s Minister of Energy and Mineral Resources, at the opening session of our first collaborative screening workshop in September in Bandung, Java. In the workshop, jointly organized by IIASA and the ministry, we aimed at laying out a plan to establish a new decision support system for the ministry, based on IIASA’s energy systems models such as the renewable energy systems optimization model, BeWhere and the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGE).
Scientific decision support systems (DSS) are a tangible crystallization of bridging science to policy. A decision support system gathers information and analytical expertise in order to improve the quality of policy making, using feedback and evaluation from previous planning and policy implementation. As a practical approach in dealing with what scientists refer as complex adaptive systems, such DSS should be able to integrate visions of long-term planning with technical details that are important for daily executed policies.

Indonesia’s energy sector is a typical example of a highly complex system. Currently, challenges of the sector are more cross-sectoral than ever. Issues that seem to have limited scopes, such as bioenergy, actually influence a broad swath of other areas including agriculture, land use change, air pollution, climate change and social equity.
For that reason, the approach we brought to the recent meeting relies on multiple models. BeWhere brings a snapshot perspective to explore energy supply options that best meet the objective set by policy makers, such as cost efficiency or least CO2 emissions, based on location specific energy demand, resource and infrastructure availability. On the other hand, MESSAGE brings a more macroscopic perspective, looking at various scenarios that project optimal solutions of meeting long-term energy demand in a certain region or country.
To have a truly systems perspective, the above approach cannot stand alone. Before we started looking at Indonesia’s energy sector, we had engaged local researchers in the tropics to localize IIASA’s Gobal Biosphere Management Model (GLOBIOM). GLOBIOM is used to analyze the competition for land use between agriculture, forestry, and bioenergy, which are the main land-based production sectors. Clearly, investigating further into the energy system will allow us to grasp a more holistic understanding and develop solutions to tackle challenges in tropical countries.
As one of IIASA’s pilot countries in the budding TFI, Indonesia represents conflicting realities of the tropics, which are essential to the planet’s well-being. Tropical forests help regulate the Earth’s climate system, while being home to huge biodiversity, millions of plant and animal species. However, the region is also highly challenged by domestic development needs and the growing consequences of a globalized economy. Abundant natural resources and land-intensive agricultural commodities, together with intensified infiltration of global supply chains and complicated socio-economic structures, have resulted in severe ecological pressures that are harmful to the region as well as the planet.
The TFI aspires to address such complexity by applying systems analysis together with regional policymakers. Such application implies a two-fold challenge. The first one is to put together IIASA’s various scientific tools to understand the broader picture that comes out from the integration of interrelated aspects of domestic development. Secondly, working together with policymakers leads to a mutual learning process. Policymakers learn to use scientific models and tools in their decision making process. In this process, fitting the models into the local context is an inevitable step that requires intense communication between scientist and practitioners. Eventually, this process will also benefit researchers by giving them a better understanding of the issue, and opening opportunities for further scientific investigation on new topics.

Q What is sustainable development and why is it important?
A As Brundtland put it, sustainable development meets the needs of the present without compromising the ability of future generations to meet their own needs.
If we do not achieve sustainable development, we will fail to provide even the barest essentials of life—food, water, and shelter—for the growing population. The extra two billion people that will inhabit the world in 2050 can only be accommodated if we are serious about sustainable development.
On a personal level I care about sustainable development because I care about the future, I care about young people, and I care about humanity. Achieving sustainable development is, in my opinion, the single most important issue we face today. Without it, all life on Earth is in jeopardy.
The Global Environment Facility (GEF) was created on the eve of the 1992 Earth Summit in Rio to assist in the protection of the global environment and promote sustainable development. The benefits of such an endeavor have only become clearer over time. It is no coincidence that in 2015 all nations of the world will adopt a set of sustainable development goals which place a strong emphasis on the “global commons,” and that in parallel we have a new global agreement on climate change within reach.
How do you see the world in 2050? What are your most optimistic and pessimistic visions?
I am an optimistic person so I will say that, by 2050, every government, every business, and every individual will take the environment into consideration in all their actions. By 2050, we will all be caring for the Earth, taking responsibility for the use of our planet’s resources, and building economies which will leave no one without dignity or necessary subsistence. We will live within safe planetary boundaries. Pessimism is not an option for me.
How can science help the world achieve sustainable development?
Science plays a critical role. We need it to monitor the state of our resources, the impacts of our activities, and the progress being made. Science can also help identify solutions. It can help encourage businesses to make smart decisions, for example, about saving money though energy efficiency, risk mitigation, and new revenue opportunities driven by innovation and new business models.
Sustainable development is a truly cross-cutting endeavor: it spans many sectors, from agriculture to economics, and transcends national boundaries. Science can play an important role by producing research that is integrated, cross-sectoral and international. In this way, synergies, co-benefits, and trade-offs can be explored in order to identify the smartest paths to achieving multiple sustainable development goals at the same time

How do you see the role of Global Environment Facility in implementing the Sustainable Development Goals?
The GEF is uniquely placed to support the global commons—the planet’s finite environmental resources that provide the stable conditions required for a sustainable, prosperous future for all. Our new strategy—GEF2020—lays out an ambitious vision for the GEF, aimed at addressing the underlying drivers of environmental degradation and delivering integrated, holistic, solutions. We are building on more than 20 years of experience providing support to over 165 countries. By working with national governments, local communities, the private sector, civil society organizations and indigenous peoples, we help find and implement integrated solutions to global challenges.
What are the advantages of a cross-sectoral and cross-border approach to identifying paths to sustainable development?
Many environmental challenges and threats to sustainable development do not respect borders. Moreover, they are often interdependent, or share common drivers. For example, biodiversity loss and climate change is partly driven by unsustainable forest management, which is in turn connected to production of globally traded commodities like palm oil or soy. Problems like this require an integrated, cross-cutting approach.
Given the importance of cross-sectoral interventions, at the GEF we will be implementing a program of integrated approach pilot projects. We believe that these will help countries and the global community in tackling underlying drivers of environmental degradation. I am also very excited about a research program we have recently launched in partnership with IIASA and the United Nations Industrial Development Organization, focusing on development and implementation of integrated solutions to tackle the water-food-energy nexus.
