Sustainable Development as seen by Jeffrey Sachs

A guest article for The Economist by Jeffrey Sacha of Columbia University. This short article is a good way to end the assigned readings for this course.  My personal concern is the lack of a road map regarding how to get there from here. I do not think that the global problem is one of describing or even visualizing a sustainable society, what we need is a real commitment to get there from here. That is what is lacking.

The next frontier

CLIMATE science tells us unequivocally that we need to “decarbonise” much of the energy system by the middle of this century. Yet advanced techniques for extracting fossil fuels—fracking, new deep-ocean drilling and the like—dominate today’s economic and political discussion. These measures may temporarily boost the economy but they would end up crowding out investments in low-carbon technologies. A boomlet in fossil fuels is bound to be a dead end. Short-term priorities and long-term needs are at odds.

This disconnect also exists in the realm of jobs policy. Youth unemployment is stuck in the stratosphere in part because conventional jobs have succumbed to advances in information technology, robotics and outsourcing, leading to lower employment and a decline in earnings among unskilled youth in particular. In response economists obsess about policies to manage demand. But that will not address these structural changes. New strategies in education and training, and in smoothing the tricky school-to-work transition, are also needed.

These examples illustrate the difference between mainstream economics and the policies that are needed to deliver sustainable development. Standard economic policies aim for growth, full stop. Sustainable development aims for growth that is broadly shared across the income scale and that is also environmentally sound. Mainstream economics divorces the short term from the long term. There may be big problems ahead—climate change, food scarcity, demographic shifts and poorly trained young people—but macroeconomists prefer to improvise today and worry about the future later. That approach also suits politicians, aligning the policy cycle with the electoral cycle. But it is not a recipe for producing robust, inclusive growth.

Global goalkeeper

Resolving this problem requires a new approach. On September 25th governments will meet at a special event at the United Nations. Part of their task will be to establish a road map that will lead, by 2015, to a set of “Sustainable Development Goals” (SDGs). Sceptics will scoff that a UN framework will make no difference to the problems of the world economy. They are wrong.

The UN’s Montreal Protocol successfully brought together scientists, industry and government to head off world-threatening ozone depletion. New technologies were spurred and rapidly diffused as a result. The SDGs will themselves succeed the UN’s Millennium Development Goals (MDGs), a blueprint for helping the world’s poorest people that has already achieved historic results in sub-Saharan Africa—including a drop in malaria deaths by at least a third from the peak and the saving of millions of lives by the introduction of new vaccines.

When the new SDGs are set, they should start by confirming the success of the MDGs and making a commitment to the end of extreme poverty by 2030, a goal recently adopted by the World Bank. They must also tackle more novel problems, including the transition to low-carbon energy by 2050; the protection of critically endangered biodiversity; the improvement of farm yields with reduced environmental costs; and the reshaping of cities to be much more energy-efficient and resilient to rising temperatures and sea levels.

Setting goals is one thing; achieving them quite another. All of these SDGs would require an overhaul of technology systems, whether for health, energy, transport, food supplies or safer cities. Target-driven technological change of this sort is very different from the normal evolutionary path of established industries competing through incremental changes in products and processes. We are perhaps more familiar with targeted technological change in the military context (the Manhattan Project, to take an obvious example) but there are enough civilian cases (the Moon landing, the Human Genome Project, the eradication of smallpox) to identify three elements of success.

The first is “backcasting”. Rather than saying with a shrug that the world will get to where it gets in terms of low-carbon energy in 2050, the SDGs should start with what is needed to achieve climate safety (for example, to stop a global increase in temperature beyond 1.5°C or 2°C). That goal defines a set of possible energy pathways to 2050 and a cumulative amount of greenhouse-gas emissions that are consistent with it.

The second element is “road-mapping”. The technologies needed for a low-carbon world, for example, are already in sight. They include renewable energy, energy storage, carbon capture and sequestration, electric vehicles and (safe) nuclear energy. But they are at very different stages of development. Some are already commercially viable. Others are still on the drawing board. Technology road-mapping identifies the obstacles to commercialisation and plans a 10-20-year research, development and demonstration strategy. Moore’s law, the sustained doubling of the number of transistors per integrated circuit every two years during the past 55 years, has been supported by a systematic, ongoing, industry-wide road-mapping process to identify, and then clear away, looming obstacles.

The third step is global co-operation, of the kind that in the past has helped reverse ozone depletion, develop new drugs for tropical diseases, improve seed varieties and create international standards and processes for aviation safety. The MDGs were successful in part because they gathered together public-health experts, industry leaders and government officials to create a new public-health ecosystem. Collaboration of this sort would accelerate progress in all sorts of areas, from the prevention of flooding in coastal cities to the development of high-yield seed varieties with preferred traits such as saline resistance, flood tolerance and drought resistance.

Getting from A to SDG

Nobody can be exempt from the next round of global goal-setting. The current economic crisis is global. China and America, the world’s two largest economies, are both beset by deepening social and environmental problems. In the next phase of global development there will be no clear division between leaders and followers. All countries will be pioneers. Just as the MDGs opened new pathways to disease control and poverty reduction, the SDGs have the potential to open up a new era of technological and organisational breakthroughs. They can lead to a better life in the coming decades and unleash a wave of growth-creating investments along the way.

NEW YORK – Tacloban in the Philippines has now joined the growing list of cities – including New Orleans, Bangkok, Moscow, New York, Beijing, Rio de Janeiro, and Port-au-Prince, to name just a few – pummeled in recent years by climate catastrophes. Many of the world’s largest cities, built on seacoasts and rivers, face the threat of rising sea levels and intensifying storms. So the new global development agenda now taking shape should empower cities to help lead the way to sustainable development in the twenty-first century.

CommentsView/Create comment on this paragraphThe importance of cities in today’s world economy is unprecedented. Until the Industrial Revolution, human history was overwhelmingly rural. Only around 10% of people lived in cities. Today, the share of urbanites is around 53% and is likely to rise to around 67% by 2050.

CommentsView/Create comment on this paragraphBecause per capita incomes are higher in cities than in rural areas, the world’s cities today are estimated to account for more than 80% of global income, with the largest 600 accounting for around half. Most of the new jobs over the next few decades will be created in cities, offering livelihoods to hundreds of millions of young people and, as China and Brazil have demonstrated, helping to slash extreme poverty.

CommentsView/Create comment on this paragraphCities are also the innovation hubs for public policy. Every day, mayors are called on to get the job done for residents. They are the ones responsible for providing safe water, garbage collection, safe housing, infrastructure, upgraded slums, protection from disasters, and emergency services when catastrophes hit. So it is not surprising that while national governments often are paralyzed by partisan politics, city governments foster action and innovation.

New York City’s outgoing mayor, Michael Bloomberg, worked relentlessly to implement a new sustainability plan (called PlaNYC). And the city’s incoming mayor, Bill de Blasio, is championing a bold program of educational innovations to narrow the vast gaps in income, wealth, and opportunity that divide the city.

Social inclusion means that all members of society – rich and poor, men and women, majority and minority groups – should have equal rights and equal opportunities to benefit from rising prosperity. And environmental sustainability means that we must reorient our economies and technologies to provide basic services like safe water and sanitation, combat human-induced climate change, and protect biodiversity. Achieving these three goals will require good governance, public finance, and effective institutions.

Not only do they face direct threats; they also have the best opportunities to identify and deliver solutions. As high-density, high-productivity settlements, cities can provide greater access to services of all kinds – including energy, water, health, education, finance, media, transport, recycling, and research – than can most rural areas. The great challenge for cities is to provide this access inclusively and sustainably.

Cities need to upgrade their governance, to allow for a greater role for poorer and more marginalized communities, and to enable much more effective coordination across city lines when a metropolitan area is home to many individual cities. Metropolitan governance is therefore crucial, as smart cities require networks that operate at the metropolitan scale.

If this metropolitan area were a country, it would rank about 14th in the world in GDP terms.

Cities and Sustainable Development

NEW YORK – Tacloban in the Philippines has now joined the growing list of cities – including New Orleans, Bangkok, Moscow, New York, Beijing, Rio de Janeiro, and Port-au-Prince, to name just a few – pummeled in recent years by climate catastrophes. Many of the world’s largest cities, built on seacoasts and rivers, face the threat of rising sea levels and intensifying storms. So the new global development agenda now taking shape should empower cities to help lead the way to sustainable development in the twenty-first century.

The importance of cities in today’s world economy is unprecedented. Until the Industrial Revolution, human history was overwhelmingly rural. Only around 10% of people lived in cities. Today, the share of urbanites is around 53% and is likely to rise to around 67% by 2050.

Because per capita incomes are higher in cities than in rural areas, the world’s cities today are estimated to account for more than 80% of global income, with the largest 600 accounting for around half. Most of the new jobs over the next few decades will be created in cities, offering livelihoods to hundreds of millions of young people and, as China and Brazil have demonstrated, helping to slash extreme poverty.

Cities are also the innovation hubs for public policy. Every day, mayors are called on to get the job done for residents. They are the ones responsible for providing safe water, garbage collection, safe housing, infrastructure, upgraded slums, protection from disasters, and emergency services when catastrophes hit. So it is not surprising that while national governments often are paralyzed by partisan politics, city governments foster action and innovation.

In the United States, for example, Martin O’Malley, Baltimore’s former mayor and now Maryland’s popular governor, pioneered the use of advanced information systems for urban management. New York City’s outgoing mayor, Michael Bloomberg, worked relentlessly to implement a new sustainability plan (called PlaNYC). And the city’s incoming mayor, Bill de Blasio, is championing a bold program of educational innovations to narrow the vast gaps in income, wealth, and opportunity that divide the city.

Sustainable development offers a new concept for the world economy in the twenty-first century. Rather than focusing solely on income, sustainable development encourages cities, countries, and the world to focus simultaneously on three goals: economic prosperity, social inclusion, and environmental sustainability.

Economic prosperity speaks for itself. Social inclusion means that all members of society – rich and poor, men and women, majority and minority groups – should have equal rights and equal opportunities to benefit from rising prosperity. And environmental sustainability means that we must reorient our economies and technologies to provide basic services like safe water and sanitation, combat human-induced climate change, and protect biodiversity. Achieving these three goals will require good governance, public finance, and effective institutions.

Cities will be in the front lines of the battle for sustainable development. Not only do they face direct threats; they also have the best opportunities to identify and deliver solutions. As high-density, high-productivity settlements, cities can provide greater access to services of all kinds – including energy, water, health, education, finance, media, transport, recycling, and research – than can most rural areas. The great challenge for cities is to provide this access inclusively and sustainably.

A significant part of the solution will come through advanced technologies, including information systems and materials science. The information and communications revolution has spawned the idea of the “smart city,” which places the relevant technologies at the heart of systems that collect and respond to information: smart power grids, smart transport networks (potentially including self-driving vehicles), and smart buildings and zoning.

The advances in materials science open the possibility of much more energy-efficient residences and commercial buildings. Cities also give rise to the opportunity to combine public utilities, as when urban power plants use the steam released in electricity generation to provide hot water and heating to residents.

Yet technology will be only part of the story. Cities need to upgrade their governance, to allow for a greater role for poorer and more marginalized communities, and to enable much more effective coordination across city lines when a metropolitan area is home to many individual cities. Metropolitan governance is therefore crucial, as smart cities require networks that operate at the metropolitan scale.
