2015 marked a historic turning point. The sustainable development goals (SDGs) unanimously adopted by the United Nations last September provide an aspirational narrative and specific targets for human development: a world free from hunger, injustice and absolute poverty; a world with universal education, health and employment; a world with inclusive economic growth, based on transparency, dignity and equity.
The 17 SDGs’ call for “global citizenship and shared responsibility” and provide legitimacy for a new global social contract for a grand transformation toward a sustainable future. They fully acknowledge the scientific advances achieved during the last three decades that have established compelling evidence that otherwise, as the UN general assembly warned, “the survival of many societies, and of the biological support systems of the planet, is at risk.” Humanity has pushed the Earth system and its global commons to their limits and the SDGs provide us with the long-needed paradigm shift towards realizing the opportunity of a sustainable future for all.
The climate agreement adopted in Paris last December has further strengthened understanding that our society depends on sustainable stewardship of the global commons, shared by us all – and particularly on the stability of the climate system. The Earth system can no longer be viewed as an economic or social externality. Last year we moved beyond the traditional view of global commons as merely the common heritage of humankind outside national jurisdiction. Now we must move beyond national sovereignty to deal with the Earth system and human systems holistically, as the SDGs require. The Paris agreement is a huge step in the right direction.
Time is running out, so we must take urgent action to implement the UN 2030 agenda. Just 14 years are left – less than the wink of an eye in the history of human development, or of the Holocene’s stable Earth systems. But where to start? Which of the 17 goals, which of the 169 targets should be tackled first? Policy makers, the media, civil society and scientists all ask these questions.
However, the 2030 agenda stresses that the SDGs are indivisible and integrated – and cumulative, since efforts to achieve them must be sustained well into the second half of the century, especially in preserving the regulating function of the global commons, Some of the goals, such as SDG13 on climate, must operate on a time scale longer than century.

Moreover, there are interactions between and among the SDGs. For example, achieving SDG7, the energy goal, could jeopardize SDGs related to water, health and climate. Tackled in harmony, however, these goals can support one another: there would, for example, be clear health benefits from reducing indoor and outdoor air pollution through global decarbonization. Jointly implementing all the SDGs would contribute both to further human development and to safeguarding the commons and the stability of the Earth systems. Importantly, joint implementation that avoids silo-type thinking would be cheaper and faster than tackling them separately.
All these goals should be achieved in such a way as to maximize synergies and minimize investment costs and trade-offs. The SDG credo “leave no one behind” also applies to the SDGs themselves. They are indivisible. We have to deliver on all of them if we want to succeed.
The SDGs are very ambitious but it appears that tackling them together will help humanity make rapid progress and enter a new era for human societies and the Earth system. Yet, many interactions – and their scope – are unknown, and this hampers holistic policy making. We lack clear understanding of the benefits of achieving SDGs and of costs of inaction, especially when it comes to regional and national differences. We urgently need this fact-based information.
We have a plethora of knowledge, but need new ways to synthesize, integrate and share it so as to use its full potential in support of the SDGs and the global commons. Science – one of the strongest voices of the environment in governance – must become more active and leave its ivory tower to engage more intensely with other stakeholders.
This is why we at IIASA, together with the Stockholm Resilience Center, and the Sustainable Development Solutions Network have launched the scientific initiative The World in 2050 (TWI2050), designed to provide the scientific knowledge to support the policy process and implementation of the 2030 agenda.
TWI2050 aims to address the full spectrum of transformational challenges in fulfilling the SDGs in an integrated way so as to avoid potential conflicts among them and reap the benefits of potential synergies through achieving them in unison. This requires a systemic approach.
The time for “climate-only” or “economic development-only” approaches is over. We urgently need an integrated understanding of the processes that account for the inter-linkages between the economy, demography, technology, environment, climate, human development, all global commons and planetary boundaries. TWI2050 brings together leading policymakers, analysts, and modelling and analytical teams to collaborate in developing pathways towards the sustainable futures and policy frameworks necessary for achieving the needed transformational change.
Such a grand transformation goes beyond a purely technology-centered view of the world or the substitution of one technology by another. It encompasses social and behavioral changes at all levels, as well as technological ones. Incremental changes, now being experienced in some areas, are useful but will not suffice: we have waited too long and the window for action is closing rapidly in some domains including such global commons as climate. We will need radical changes in human behavior and technological paradigms. TWI2050 will look beyond 2030 to 2050 – and, in some cases, even to 2100 – to draw a vision of the world where the SDGs are eventually fulfilled.
The SDGs and the Paris agreement show what institutional international governance can achieve with joined forces. We have entered a new era of global governance, acknowledging the complexity and the connectivity of human development with the global commons and the Earth system. TWI2050 hopes to serve the global community with the best science available in tackling these key global challenges for humankind.

There are many challenges confronting decision makers in building robust and effective policies. They must balance pressing short-term needs with long-run challenges. They must confront these varying demands while facing imperfect knowledge of the complex systems (i.e. the economy, the environment, etc.) in which their policies will have impact. Above all, they also face the same uncertainty about the future as the rest of us, making perfect prediction about future outcomes impossible.
Nevertheless, decision makers must make choices in response to future challenges; inaction itself is an implicit choice, as change is inevitable. The challenge is to find a way to improve decision making, and in Multi-factor, multi-state, multi-model scenarios: exploring food and climate futures for Southeast Asia, recently published in Environmental Modelling Software, we believe we have presented a unique methodology to improve the decision-making process, by leveraging a participatory stakeholder-driven scenario development process with a multi-model ensemble to interactively explore future uncertainty with regional stakeholders.
This methodology was first applied in a workshop in Vietnam, where a diverse set of stakeholders from a wide range of sectors in Cambodia, Laos, and Vietnam collaborated to develop four multidimensional scenarios focusing on future agricultural development, food security, and climate change. Through building these multidimensional scenarios, stakeholders were challenged to consider potential interactions between varied parts of complex systems, like society and the environment. By doing this with a diverse set of stakeholders from public and private sectors, participants considered the future in a holistic and multidisciplinary manner. They were asked not only how different the future might look from the present, but also how they might respond to and shape future change. In so doing, regional stakeholders gained a better understanding of future uncertainty, while introspectively reviewing their own assumptions on the drivers of change, while creating four diverse scenarios that presented challenging plausible futures.

These scenarios were then quantified and simulated using a series of climate models, crop simulation models, and economic models including IFPRI’s IMPACT model and IIASA’s GLOBIOM model. Quantifying the scenarios in models can assist decision makers by pairing the qualitative aspects of the scenarios with quantitative analysis that systematically considers complex interactions and potential unintended consequences. Doing this quantification across a multi-model ensemble maintains the scenario diversity and richness, which in turn ensures that a broad possibility space is maintained throughout the process. This offers decision makers a larger test bed in which to evaluate potential policies. This multidimensionality and diversity of scenario outputs has been well received in the region, allowing them to be adapted and reused in a variety of policy engagements in Cambodia, Laos, and Vietnam.
- In Cambodia, scenario results were used to inform their Climate Change Priorities Action Plan (CCPAP) to better target and prioritize the spending of its 164 million U.S. dollar projected budget, a policy engagement that was done over 6 to 8 months as scenario analysis and use were embedded in the CCPAP
- In Laos, scenario results were presented in a regional workshop led by CCAFS and UNEP WCMC to evaluate regional policies for economic development, agricultural development, and climate change and consider potential environmental tradeoffs
- In Vietnam, scenario results were shared in a workshop led by CCAFS and FAO to review and revise climate-smart agriculture investments proposals by considering the potential effectiveness of different investments under various climatic and socioeconomic conditions
The regional scenarios were a collaborative effort that involved colleagues from many institutions including IFPRI, IIASA, FAO, UNEP WCMC, the CGIAR research program on Climate Change, Agriculture and Food Security (CCAFS), and the University of Oxford, among others. It would not have been possible without the funding and support from CCAFS, the CGIAR research program on Policies, Institutions, and Markets (PIM),Global Futures and Strategic Foresight, the FAO’s program on Economic and Policy Innovations for Climate-Smart Agriculture (EPIC), and UNEP WCMC through a MacArthur Foundation grant.

In a new commentary (subscription required) in Nature Geoscience, IIASA researchers Michael Obersteiner, Marijn van der Velde, and colleagues write about the problems facing the world’s food supply as we exhaust our supplies of phosphorus. Projections show that phosphorus supplies could run out in the next 40 to 400 years. In this interview, Obersteiner and van der Velde give more background on the “phosphorus trilemma.”
Fertilizers containing phosphorus are vital for crop production – but phosphorus is limited in availability and growing scarcer.
Why is phosphorus so important?
MV: Phosphorus is essential for life on Earth. It is a key component of DNA and cell membranes, and vital for cellular energy processes. Crops need phosphorus to grow. And to maintain crop production, and to make sure that soils remain productive, we have to add extra nitrogen and phosphorus as fertilizer. This is one of the food security issues in Africa where soils are suffering from nutrient depletion without replenishment.
Where do we get phosphorus and why is that supply in danger?
MO: Phosphorus is ubiquitous in the Earth’s crust. However, most of it is strongly bound in the soil , where plants cannot access it. Modern agriculture (which made human population explode) essentially began when we found ways to extract nitrogen from the air and phosphorus from minerals to make fertilizers for agricultural purposes.
The problem is that minable phosphorus is geographically concentrated in very few places. For example 75% of known reserves are located in Morocco and these reserves are limited. If, for example, political turmoil restricted access to the mines of Morocco, we would be in danger of short-term shortages that could lead to rising food prices or food insecurity in poor countries.
What problems do you expect as phosphorus becomes even more limited?
MO: The biggest problem we face is limited or no access to phosphorus fertilizers by the poor and food insecure.
MV: At the same time, rich countries apply excess fertilizers causing eutrophication to their lakes and rivers, while the poor cannot afford fertilizers.
What can be done about these problems?
MV: More efficient fertilizer application would make fertilizers cheaper to poor farmers, and at the same time help address the environmental problems. But in the long run we need to figure out how to produce food in a way that recycles nutrients at minimum loss rates. (This also includes losses from human excrement!)
To better solve the issues around long-term phosphorus availability and equitable use we also need better data on how much phosphate rock is remaining in the world and where it is located. Countries will need to be persuaded to collaborate on both these issues to ensure equity.
How does IIASA research inform this debate?
MV: In a paper we published earlier this year in PLOS ONE we showed the importance of soil phosphorus and the significant increases in yields that could be achieved in Africa with balanced micro-dosed applications of nitrogen and phosphorus. Available phosphorus in soils is generally low, especially in older weathered soils in the tropics where a lot of the phosphorus can be locked up in iron and aluminum complexes. We are currently investigating what application rates of nitrogen and phosphorus would be optimal for a range of soils and climates. This can then lead to better soil and nutrient management.
MO: In addition researchers in the Mitigation of Air Pollution and Greenhouse Gases program have been very active in finding solutions to the problem. For example: http://www.iiasa.ac.at/web/home/resources/multimedia/Podcasts/Our-Nutrient-World—Wilfried-Winiwarter-on-Reality-.en.html
What should people to know about this issue?
MO: Many things in nature that we like or depend on for our livelihood are substitutable. But phosphorus is in everything we eat and cannot be substituted by any element. If we continue business as usual we will squander this resource and thereby potentially compromising the wellbeing of our daughters and sons.

There is both a need for and an interest in cooperation between science and the global business community. There are many options that we can consider on how IIASA can interact more with the private sector, creating a special business advisory panel or via cooperation agreements with companies or the World Business Council.
IIASA advisor Björn Stigson calls for cooperation between science and business.
In October 2012, I participated in IIASA’s 40th Anniversary Conference. We discussed the need for new partnerships between the science community, academia, business, and governments. If science and business communities stand together, then policymakers will be forced to listen.
The science community has developed a lot of knowledge, and can put this knowledge to better use in global policymaking. Part of this will be in cooperation with the business community.
The business community is way ahead of governments in terms of understanding challenges such as climate change and the environment. We are also way ahead of governments in taking action. But what we struggle with is understanding the nexus issues and systems analysis, which IIASA specializes in. How do we deal with the nexus between energy, food, water, land use, and similar issues? These are the areas where we need more engagement between business and the scientific community—and IIASA can provide that key focal point. But the cooperation between science, business, and governments has to overcome some challenges.
One major issue is the disconnect in the time frames that different sectors focus on. Scientists work with a long time frame, and so do businesses—investing for up to 50 years into the future. However the financial community is very short-term oriented and often focuses on the next quarter or year at most. The political system works with the syndrome “my term in office,” which normally is three to four years. This is a major disconnect when looking at long-term investments for sustainability.
Another challenge is that the scientific community often does not see business knowledge as real knowledge because it is not published and reviewed in the same way. If we can improve communication between science and business, we can join hands and go to the politicians together to say this is what is really needed and we will have a much bigger impact than we have today.
Global business has come to engage in policy issues because we depend on them. If scientists really want to influence policy then they cannot sit on the sidelines, but should be suggesting possible solutions. Both science and business must do a better job of explaining to the politicians what the solutions are—not only the problems. I am looking forward to working closely with IIASA to see how we can address many of these issues as a partnership between science and the private sector.
