The roads to 2050

By Owen Gaffney, Stockholm Resilience Center (excerpted from a post on Rethink.earth)

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.

#winwin
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

Female-headed households hit harder by climate change

By Raya Muttarak, IIASA World Population Program

Taking action on climate change is one top priority of the Sustainable Development Goals (SDGs), especially since its adverse impacts can undermine sustainable development. At the same time, reducing gender inequalities and empowering women and girls is fundamental in making progress across all the goals.

These two issues are also closely linked:  in certain circumstances, women are more vulnerable to the effects of climate change than men, for example, due to weaker physical ability, lower socioeconomic status, and greater social, economic and political barriers in coping capacity.

This is why, in recent work, we have been exploring the differential impacts of climate change on subgroups of population such as by gender, age, education, and income. The rising number of households headed by women across the world and, in particular, in southern Africa calls for special attention to their economic welfare. In general female-headed households are more likely to be in poverty. Under the context of the changing climate, it is likely that weather extremes, rainfall variability, and natural disasters associated with climate change will exacerbate economic disadvantages of female-headed households.

Female-headed households are more economically vulnerable to climate-related shocks for three big reasons, which researchers call a “triple burden”. First, persistent gender disparities in the labor market and other productive activities, including limited access to formal credit markets and land contribute to greater economic disadvantage for female-headed households. Second, these households often have a higher total dependency ratio–that is, women take care of a higher proportion of dependent children and the elderly. Third, women who are heads of households with no other adult help have a “double day burden” where they have to fulfil both domestic duties and make money outside the home. That means that female heads face greater time and mobility constraints and may have to work fewer hours or choose lower-paying jobs.

Add climatic shocks to an already disadvantaged family, and the livelihood disruption can be a catastrophe.  However, there have been very few studies of how female-headed households actually fare in the context of climate change. In our new study published in World Development, we used  household survey data from South Africa and local rainfall data over the period 2006-2012 to examine how female-headed households fare economically when facing variation in rainfall. The study provides new empirical evidence on economic welfare of households headed by women following climatic shocks.

The new and unique part of our study is that we are able to control for observed and unobserved characteristics of households using a statistical technique called fixed effects estimation, which enables us to control for the household-specific effects on income. It also lets us account for different income trajectories in households with different demographic compositions. Furthermore, we were able to evaluate the impacts of income shock on economic vulnerability of female-headed households using rainfall variability as an exogenous source of risk. Income loss due to other variables such as death of a household member or losing a job are likely to be endogenously determined by household characteristics, that is, female heads have lower level of education and hence are more likely to fall into unemployment. But because rainfall variation is not connected to household factors, we were able to measure the causal effect of climate variability on incomes, comparing different household types.

Our study shows that female-headed households in South Africa are indeed more vulnerable to climate variability than households headed by two adults, and not just because of the greater economic disadvantages that they start with. Even after controlling for household socioeconomic characteristics, female heads still fare worse when facing economic shocks. This might be due to limited access to family support and protective social networks who can step in to help in time of crisis.

Our analysis also reveals that not all types of female-headed households are vulnerable to rainfall variability. This finding is especially important for designing a policy to reduce vulnerability of female-headed households. Given different routes into female headship, we show that never-married female heads, women with a non-resident spouse (for example, where the husband has moved to work in another region), and widows have greater economic vulnerability to climate variability. The group of female-headed households where the female head has never been married is the largest of these groups. Households with adults of both genders where the female works but the male does not work and households of separated or divorced women are no more vulnerable than male-headed households.

We also found that vulnerability to climate impacts is related to the effect of rainfall on agriculture. We find that female-headed households face greater economic vulnerability only in the districts where rainfall has a large effect on loss in agricultural yields. Regardless of household engagement in agriculture, crop losses in a district can affect food and livelihood security through surges in food prices and shortfalls in local demand.

Although our study focuses on South Africa, the results showing that female-headed households are more vulnerable to climate variability call for particular interventions to their vulnerability in the context of climate change. The number of female-headed households is rising, with an exceptionally high proportion in southern African countries (36.3% in Lesotho (2006), 43.9% in Namibia (2013), 47.9% in Swaziland (2007). As climate variation and extremes also increase, policies to reduce vulnerability to climate change need to explicitly consider the plight of this subgroup of population.

Leave no SDG behind

By IIASA Deputy Director General Nebojsa Nakicenovic and Caroline Zimm, IIASA Transitions to New Technologies Program and The World in 2050 (TWI2050) initiative. (Originally published on The Guardian)

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.

As a business leader with a background in international relations, you have unique experience in both government and the private sector: How do you think that the two could work together towards achieving the sustainable development goals?
Traditionally, the two sectors have not mixed well. Governments were skeptical of the private sector’s profit motives and the private sector believed government was an impediment. Both views were, of course, short-sighted. In recent years the United Nations has looked to the private sector to help finance development as the traditional levels of fiscal policy have been removed from the toolkit by increasingly narrowly focused legislatures. Similarly, private investors and private enterprise, who make up over 60% of GDP in the developed world, realize that they can partner with governments to achieve their social goals. Yes, businesses now have social goals.

What do you see as the biggest challenge is in achieving the SDGs?
Money and willpower.

What changes would be needed in business in order to fully embrace the SDG agenda?
I suspect that businesses need to understand how they can contribute. If given the option of a regulation or a tax, businesses will always chose a tax, because it allows them to plan accordingly. So, in this case, I think businesses require an explanation as to how they can contribute and how it won’t interfere with their executing on their business plan.

Business is often seen as “part of the problem” when it comes to issues like climate change and poverty – do you think that sustainable development could also bring opportunity for business, and if so, how?
Having been in the public sector for 25 years before returning to the private sector, I have never seen the private sector as part of the problem. In the United States, the private sector contributes some 80% of GDP. The private sector also provides jobs, which is really the only way that poverty can be eliminated on a generational scale. I think that there is ample opportunity for business to contribute to the SDGs, but the public sector needs to explain clearly how businesses can contribute in a way that doesn’t interfere with their business plan. It doesn’t mean that businesses need an inducement (like a tax break), they just need to understand the strategic logic of the concept.

Interview: An occasion for innovation

Pascal Lamy was the director general of the World Trade Organization from 2005 to 2013, and currently serves as a president emeritus of the Notre Europe – Jacques Delors Institute. On 28 and 29 August he is taking part in a meeting of the Alpbach-Laxenburg Group, focused on new models for sustainable business development.

As the former director general of the WTO, you have extensive experience in global trade and economic development. How does this background inform your perspective on the issues of the sustainable development?
To put it very simply, there is a very well-understood interaction between trade and growth, starting in the 18th century until now. The understanding of the relationship between global trade and sustainable development, i.e. including the environment dimension, is much more recent, understandably because environmental issues only came into the picture much more recently than the 18th century.

The reality is today that the communities working on trade and environmental issues are rather poorly connected. You belong either to one or to the other. There are not that many people who have feet on both sides, which does not help because the issue  is complex.

In theory it’s very simple. Take climate change for instance: If you put the carbon price at the proper level, i.e. the one that takes into account the externalities of climate change and CO2 emissions, all you have to do is price CO2 properly, and problem is solved: markets will reallocate production factors accordingly.  That’s what theory tells us. The little problem is actually agreeing on a set price for the entire planet. And this triggers a lot of suboptimal propositions, solutions.

I think that the overall stance now is that that trade is not an end. Trade is a means to improve growth in climate, welfare, sustainability, including environment sustainability. This was in fact part of the WTO charter from 1994. When I was DG of the WTO we did quite a lot of work in collaboration with environmental international organizations such as UNEP for instance. We looked into the big question on this topic: Is the expansion of trade good or bad for the environment? There are arguments on both sides, and it is a vast set of issues. But overall I think there are ways and means to reconcile, to synergize the benefits of trade opening for a more environmentally sustainable world.

What do you see as the biggest challenge in achieving the Sustainable Development Goals?
It’s a very long and vast set of issues. So it’s not a single thing—what you have to address issues on inequality, on education,  on oceans, on poverty—it’s a lot of different things.

But overall, I think the biggest challenge—and this is why a number of us are working on that—is to properly organize the accountability of these SDGs. That means providing proper metrics, proper review, proper debate, and proper public accountability. Now that the goals have been agreed by the UN, the issue is whether or not they can be achieved, and whether we can properly organize public pressure on sovereign nation states, through civil society, involvement of businesses. So in my view the main issue is building and agreeing on a proper follow up transparency system.

How do you think that the private sector could help in achieving the SDGs?
In doing what private businesses have been doing increasingly, which is integrating this sustainable development focus into their global strategies. Most big businesses now have a set of principles, a set of values that include sustainability.

What’s happening for instance around the push towards green finance, notably since the COP21 in Paris, is a good example of how some businesses can be on the front line of a larger coalition. We need coalitions like this to bind public authorities at the national, regional, and city levels, to civil society organizations focused on sustainability, climate, environment, biodiversity, and development, and businesses, whether big or small.

So from your perspective it sounds like business is already on the right track. What further changes would be needed in the private sector in order to fully embrace the SDG agenda?
It will happen if and when businesses realize that it matters to their consumers, to their staff, and to their shareholders, or their finance providers more generally. This is the frame within which they have to optimize what they do—clients, consumers, their people, and where they get their financial resources from. And if these various sides of the triangle push in that direction, inevitably businesses will push in this direction. They’ll have to.

The Alpbach-Laxenburg Group brings together leaders from business, and young entrepreneurs, along with government leaders and science experts. What do you think can be gained from a meeting of this type?
What’s unusual is that it links you with people whom you may not meet every day, so it’s an occasion of diversity connecting on a topic. Plus, there is something which tends to come out of this sort of environment, which is innovation. People exchanging ideas, not just theoretically, “What should we do?” “Where are we?” “Where are we going?” but, “This is what I suggest to do,” “This is what I tried and it worked,” and “This is what I tried and it didn’t work.” It’s  more about experiences on the ground, which may then inspire more general conclusions.
