Jeffrey Sachs

Jeffrey Sachs believes that we must lift a billion-plus people out of poverty while simultaneously reducing our impact on the environment

 

Jeffrey Sachs, Columbia University professor and director of the Earth Institute, is one of our leading public intellectuals. A trained economist (who became a full professor at Harvard University when he was only 29 years old), Sachs boldly ventures into other disciplines. He is as agile citing the latest biological studies on habitat change as he is referring to obscure econometric research on monetary policy.

Unlike many academics, Sachs is committed to getting his ideas out to the public, authoring the best-selling book The End of Poverty: Economic Possibilities for Our Time and, most recently, Common Wealth: Economics for a Crowded Planet. And he is not afraid to put his theories into action. In the 1980s Sachs helped the Bolivian government fight hyperinflation; in the 1990s he helped Poland and Russia transition from communism to capitalism; and in the 2000s he worked with U.N. Secretary-General Kofi Annan to implement the Millennium Development Goals.

Because of his wide-ranging theoretical and practical work, not only is Sachs one of the few people who understand the scope of the world’s economic, social, and environmental challenges, he is also able to come up with practical solutions to solve them. Critics may question Sachs’s ideas and solutions, but they can’t question his commitment.

In this interview with Stanford Social Innovation Review Managing Editor Eric Nee, Sachs explains why sustainable development is humanity’s most pressing challenge, why lifting billions of people out of poverty is the first order of business, and why the development of new technologies offers the best hope for simultaneously increasing economic growth while reducing our impact on the planet.

Eric Nee: You have spent decades studying and trying to fix some of the world’s thorniest problems, such as economic development and poverty. How would you characterize the state of affairs?

Jeffrey Sachs: The world has become extraordinarily crowded with about 6.8 billion people. At the same time, production has become so efficient, and demand for basic resources is rising at such an extraordinary rate, that we are pressing very hard against the earth’s ecosystems. As a result, we have a remarkable amount of geopolitical change, from unprecedented economic success stories like China, to calamitous economic andhumanitarian crises like the one in the Horn of Africa.

When you add it all together, I see a crowded, interconnected, and environmentally stressed world, facing the added stress of huge political change and very deep crises in certain regions. The challenge is finding a path that brings rising levels of prosperity for all that does not simultaneously undermine the physical life-support systems of the planet—in other words, sustainable development. We’ve not figured out how to do that yet.

You have been working on economic development for more than 25 years. When did you begin to understand the ecological aspects of the issue?

For a long time I thought of the challenge of globalization mostly in economic terms—how can each part of the world find an effective role in what is quickly becoming a single integrated global economy. The more I immersed myself in those issues, the more I found out that the physical world kept intruding in ways that I had not been trained to expect and that I hadn’t worked on before. For example, the epidemic diseases that engulfed Africa, especially in the last 25 years with the spread of AIDS, but also the resurgence of malaria and other killers.

As I began to look more closely at those issues, and especially as I got more involved in the rural challenges in south Asia, Africa, and Latin America, the fragility of the resource base became a more and more dramatic signal that something was wrong. I was seeing it with my own eyes. Entire regions were trapped in famine by repeated droughts, where the short rains had essentially disappeared entirely and the land was so degraded that large areas were bereft of reliable crops.

None of this is novel to an ecologist or to those who have been in the forefront of environmental challenges. I discovered it by wending through this maze of challenges, starting from macroeconomics, moving on to development, coming to realize the impact of disease, food production, and hunger, and more recently dealing with challenges like energy, climate change, and water.

A problem of this magnitude can seem unsolvable. How do you make it a manageable problem that people believe can be solved?

As we train ourselves to address these problems we need to be able to pull them apart to their constituent components. But we also need to be able to go in the other direction, because many of the areas of expertise and technology that are a part of the solutions are now inside silos. The intellectual and practical tasks are both to take a large problem and put it into manageable components, and at the same time move in the other direction that brings different parts of the university, different parts of our knowledge system, and different parts of government together so that we can find the cross-linkages.

You’ve identified two institutions, universities and government, that are some of the most resistant to change.

I think government is the harder one to change. Universities have increasingly recognized that the problems we’re addressing don’t come packaged by departments. There’s a tremendous amount of ferment in universities—new programs, more interdisciplinary work, new institutions. Great universities recognize not only that they are engaged in the research and teaching of disciplinary expertise, but that they also have to be engaged in problem solving. Problems don’t always come packaged the way we would like them to be, and sustainable development absolutely does not come packaged according to traditional lines of faculty or departments. I’m rather optimistic about what I’m seeing at the universities, as long as the spirit of the university is to engage deeply as a participant in actual problem solving and not see itself as an outside scorekeeper or observer.

How do we tackle the problem of sustainable development?

I view the sustainable development challenge as having two components. The first component is to address the problem of extreme poverty, because this is a challenge that claims millions of lives every year. In addition, there is the challenge of finding a way to have long-term development consistent with environmental sustainability and the conservation of ecosystem functions.

The most urgent task is to address the needs of the poorest of the poor. For them, every day is a struggle for survival, and millions, perhaps 10 to 20 million, lose that struggle each year. These are tragedies that are so dramatic and so unnecessary in their scale that we need to turn our attention to them. They’re also dangerous for the planet because these are the places that end up in chaos, violence and war, in mass movements of population, and unfortunately where Americans end up sending troops and getting enmeshed in problems that can’t be solved through military means.

I’ve identified six areas that I think are crucial to ending extreme poverty—agriculture, health, education, infrastructure, business development, and environmental conservation—and that can be defined in very implementable and practical terms. I’ve been arguing for the past decade that we can make tremendous headway against poverty, killer diseases, the lack of productivity of the rural poor, and so forth, through integrated systems-based and technology-based approaches in those six areas.

Even if those problems were to be addressed adequately and quickly, it would not at all solve the other overarching problem on the planet. In fact, it would probably exacerbate it mildly, though not very much. And that’s the fact that—putting aside the billion to a billion and a half poorest people—the five and a half billion others on the planet are already using resources at such a level, and are tending to increase their resource use at such a rate, that the trajectory of global society is unsustainable.

What areas should we focus on to become more sustainable?

The first is to develop sustainable agriculture. Agriculture accounts for about a third of all greenhouse gas emissions. It also accounts for the predominant challenges of hydrology, invasive species, habitat destruction, and so forth. We need to focus on sustainable agriculture in far more thoughtful ways than we have. There’s plenty of brilliant insight and technical possibility for quite significant progress. The second huge area is the way we deploy energy. I think everybody now recognizes that energy needs to be overhauled, partly because of the stresses of conventional energy sources and also because of its environmental impacts, especially related to climate change and ocean acidification.

The third area is the host of industrial ecology challenges. These are the traditional pollutants, toxics, and waste products that come from poorly engineered industrial systems. The fourth thing we need to do is to get control over the global population. If we don’t, we’ll find that many of the solutions we’re able to muster will keep getting overwhelmed by the added billions of people on the planet. Although population growth has largely disappeared from public discourse, it remains a very serious issue.

The fifth area is that even if we address agriculture, energy, industrial ecology, and population growth, there are regions of the world that are at risk of becoming essentially nonviable in the next 50 years because of the climate change that’s already under way. Typically, these will be among the poorest places in the world, partly because environmentally marginal places cause poverty and partly because these environmental shocks will increase the numbers of people trapped in poverty.

In which of these areas are we making the most headway?

On the poverty side, there have been some huge advances in disease control in the last 15 to 20 years because of new vaccinations and new mechanisms for enabling poor countries to take up these vaccines. The Gates Foundation has had a major role in all of this. There’s a new, proactive, and increasingly effective campaign against malaria, which is showing tremendous results. There are some glimmers of breakthrough in the chronic food crisis of Africa by showing how the yields per hectare can be dramatically increased even in very poor places. The leader of this in recent years is a very poor country in south central Africa—Malawi. You can find these success stories, but at the same time they don’t reach the continental scale and certainly not the global scale.

An area where there has been a big impact is information and communication technology. It is the one area of technological advance that’s now dramatically penetrating the poor world on a market basis. The most important example of this—and it’s more than an example, it’s a transformation—is the spread of mobile phones to virtually every village in the world. Five years ago in the villages where I was working there wasn’t a mobile phone in sight. Today, on average, perhaps 25 percent to 30 percent of the households in these villages own their own mobile phone. This digital connectivity provides a new platform for the successful delivery of other technologies and transformative changes.

Turning to the environment, we have a tremendous portfolio of promising technologies: new ways to bring safe nuclear energy; new ways to harness, transmit, and store wind and solar energy; and breakthroughs in electric vehicles, battery storage, and integration of electric propulsion with information and communication technologies that are going to make cars not only low emission but also a lot smarter.

In agriculture, there are many new smart agricultural systems. There’s a whole field of agroecology, low-till agriculture, integrated pest management, microdose fertilizer, better and more efficient water management, biotechnologies for drought-resistant crops, and other ecologically sound farming methods.

Of course, the solutions to these problems are not solely technological.

There are some areas of success in both poverty alleviation and environmental sustainability, but in neither case are we close to achieving a globally scaled approach to real solutions. That’s because the defining aspect of both of these challenges is that they won’t be solved by markets. They require political decisions, and political decisions require political will. Not the political will of leaders, because our leaders are mostly followers. It requires societies to decide to act in their interest, in the interest of others on the planet, and in the interest of future generations. That is hard, because it requires public consensus that needs to be built on an understanding of these problems in their mechanistic sense, as well as the development of shared values that these problems are important to address.

One of the challenges is that these problems have come much faster than our understanding or our institutions can accommodate. The rise of China and India and the implications of that for global energy, food, climate functioning, as well as geopolitics and the nature of the world economy, have happened so fast that we barely have begun to comprehend it in a deep way. We have considerable widespread anxiety, but we don’t have a lot of healthy institutional change.

Most of the institutions that are charged to deal with these problems are post-World War II institutions like the United Nations, or departments of government that were created in the 20th century along structural lines that are not equipped to understand these challenges or to treat them in a holistic way. The world has not developed a political or ethical sensibility of a global society.

One can find overwhelming reasons for optimism that there are technical solutions to these problems. You can even define technologies that either exist or are within reach in the next 10 to 20 years that could achieve a global scale to make a profound difference on both of these challenges. But they don’t add up to global problem solving yet.

One only has to look just off our southern shore at Haiti to see that these problems are still with us.

Exactly. Haiti demonstrates so many tragic aspects of neglect. Low-cost structural reinforcement of buildings could have saved tens of thousands of lives. The tragedy also demonstrates the unanticipated, bizarre, and damaging consequences of U.S. actions vis-à-vis Haiti over the last 30 years, such as putting on trade embargos to try to create political change that instead ended up destroying the economy. And all of this is happening an hour or two flight off of our border. So yes, it’s a compelling demonstration of how we’re just not quite getting this right yet.

    I want to thank Jeff Sachs, for giving us hope. There is too much cynicism, ignorance and despair everywhere, but you really help us to see the world in a far more encouraging way.

    We won’t do anything, because there is no global we. We are completely overwhelmed by problems of our own making –  which includes, above all, the destruction of us. Dr. Sachs seems to be correctly identifying our problems, while ignoring the main one – that people have ceased to exist, in the sense of people who are aware and in control – both key properties of human existence. We have no word to define what we are, but we seem to be hollow shells.

    Q. What can be the integrated planetary sustainable solutions in a scenario where:

    (1) A crowed and still crowding planet is putting ever increasing pressures on renewable, not-so-renewable, and non-renewable resources, and

    (2) The ever increasing consumption and associated toxic foot-prints of the top of the population pyramid is having a continuous cascading catch-up effects to successive bottom layers?

    A. There must be a cap to both the factors. No rocket science! The 1st cap applicable to poor but biologically productive (population/countries); the 2nd cap to rich but biologically under-productive. Unless there is a trade/policy bargain between these two caps, I don’t see much voluntary progress towards a sustainable sustainability on a global scale.

    Poverty alleviation and environmental sustainability require more than a technology fix and won’t be addressed by markets, as Sachs notes. Political action theoretically follows political will, which derives from the electorate (in democracies.) As we have seen however, part of the thinking and behavior of people with any degree of material affluence is a reliance on “experts,” business leaders and politicians…partly because these issues involve complex and dynamic systems most people aren’t educated to understand, and partly because “success” is often accompanied by a detachment from these “intractable, unsavory” matters. And so the circle goes round and round - politicians prioritize getting elected and claim there is little political will on these tough, transregional decisions, while citizens assume politicians are making everything alright. In the meantime, globalized business pursues profits, which as we know by now, often come at the cost of resources we all depend on to live healthfully (clean air, water, soils, biological diversity, etc.)

    The rules of the game (survival or thriving) have changed, but most of us keep playing with assumptions, tools, and aspirations that keep us locked in this tail-chasing dilemma. Also, the rising costs and complexities of our outdated development model have the unfortunate effect of discouraging many from thinking differently, much less getting involved. Still, the planet holds us accountable whether we realize it or not… Perhaps the most effective approach is to hold up specific examples of projects that do make a difference, so that the various protagonists can see the benefits of changing our MO.

    Human race is feeling dangers of the so called development, where there is always room for debate. Sustainable development in all the communities is being realized. Should it be the center of action? In democracies, there are a lot of political compulsions arising within the nations and between the nations that a large part of the resources is being allocated to the activities that are harmful to the concept of the sustainability. They are giving short political gains. Even people are mis-informed about the harms and benefits of such strategies. Five main areas for the sustainable develpoment noted by Dr. Sachs, requires strong political will by the Governments and other functionaries of civil society. Development may require different inputs for different communities and countries, but sustainablity of development and larger issues of environment protection are burning questions in front of the mankind, and they are going to be more critical in near future.

    With all said, I agree that a change in the attitudes among the people of the earth being firs for making a real difference in moving the political machine into action. I can only speak for myself and the attitudes of my peers. I see so much wasted time and money spent on frivolous luxury items and not enough true earth saving practices. The time has come to unite the world on a global task to work together and put the earth and its inhabitants first. Disease and famine are ignorant byproducts of people not caring enough to help themselves and the world around them. I see it everyday right here in my own neighborhood. Ignorance abounds not because the technology dosen’t exsit. The only hope for the people is, for the intectuals to come up with easy enough ways for them to slide into these changes without even noticing. Good luck and thank you for trying.

  • I must thank Dr. Sachs for his enlightening view on global issues and for highlighting such a colossal mega-problem for just any one party or few parties to handle, much less solve. I think the root of the problems that humanity face today be it environmental degradation, climate change, poverty, chronic disease is a result of mankind adopting a secular approach to life, divorcing ourselves totally from the Creator and therefore to a sense of accountability of one’s action; by not believing in the next life and totally hogwashing the coming of the Day of Judgement. The Book of Final Revelation (the Quran) states;” Do not spread corruption on earth after it has been so well ordered.” (7:56) (The Message of the Quran ; Translation by Muhammad Assad)  So the antidote of mankind’s seemingly perpetual malaise is to go back to just two fundamentals; belief in the One True God and belief in the Day of Judgement and read the Quran.

  • The problem I find with publications such as this, is that the author’s experience of both poverty and the cultures in which they exist are limited. It’s all well and good having social engineering theories on how to end poverty, but all previous attempts seem to have failed due to unforeseen environmental factors.
