Sustainability’s wademecum: from theory to practice
The author’s book starts with the general assumption that sustainable
development is both a way of looking at the world, with the focus on the
interlinkages of economic, social, and environmental aspects and a way of
describing shared aspirations for a decent life, combining economic
development, social inclusion, and environmental integrity. That is,
sustainable development is both an analytical theory and a normative framework;
a way of understanding the world, and a method for solving global problems*).
*) Jeffrey D.
Sachs. The Age of Sustainable Development.
- Columbia University Press, New York. 2015. xvii + 543 pages. ISBN:
978-0-231-17315-5.
The UN Secretary General in the foreword to the book
optimistically underlined that “sustainable development is the central
challenge of our times” and that “it is critical that we understand how
sustainable development can be achieved in practice, on the ground, in all
parts of the world”. Suggesting sustainable development goals (SDGs) as global
strategy, the UN chef sees the difficulties with the convergence to
sustainability as a major strategic issue in all countries.
Jeffrey D. Sachs wants to accomplish this noble task
in his book: over and over again, he tries to persuade the reader what
sustainable development is or should be about, and how it can be put into
practice, in various sectors and in the regions of the world.
In the first chapter, the author underlines the so-called
“objective assumption” of increasing global population - “our crowded planet”;
there are now about 7.5 billion people on planet Earth, roughly 9 times the 800
million lived in 1750. At the same time, the global GDP reached about US$
12,000 per person: it means that the annual world output has been at least 100
times larger than at the start of the first industrial revolution. That
250-fold increase in total world output (or even a thousand-fold increase in
certain economic activities) results in multiple kinds of damage and
destruction, especially so as the worldwide established technology in very many
cases has been highly resource-intensive and heavily polluting, making nature
the great loser in global development.
Sachs’ conclusion on the global threats is dramatic: “the
gigantic world economy is creating a gigantic environmental crisis, one that
threatens the lives and wellbeing of billions of people and the survival of
millions of other species on the planet, if not our own” (p. 2).
Besides, the environmental threats are rising on several
fronts at the same time: climate change, shortage of fresh water, chemical
pollution of oceans and threatening habitat of other species, etc. And the
Sachs’ answer to these threats is not “de-growth”, but “sustainable
development”.
The normative side of sustainable development should
envision four basic objectives of a good society: economic prosperity, social
inclusion and coherence, environmental sustainability and good governance by
major “social actors”, including governments and businesses.
This basic concept is Sachs’ working definition of the normative objectives of sustainable
development. The word ‘sustainable’ could be used together with “environmental
integrity” (or resilience), however, good governance is debatable too.
To demonstrate the real challenges, Mr. Sachs looks at inequality
in the world (ch. 2). Not only are there huge differences in incomes between
the industrial countries and the least-developed countries, there is also great
urban-rural inequality, and income inequality within countries.
In chapters 3 to 5, he examines the processes of convergence
versus divergence in order to better
understand why some countries are developed while others stayed poor, and how
to get on to a trajectory of convergence to end extreme poverty.
In order to eradicate extreme, Sachs calls for “clinical
economics” – in the sense of making a diagnosis that is accurate and effective
for the conditions, history, geography, culture and economic structure of the
country in question.
Chapter 6 is an exploration of the concept of “planetary
boundaries”: the author concedes that “we live in a world already bursting at
the seams, with humanity pushing against planetary boundaries” (p. 199), and
asks whether further economic growth can be reconciled with environmental
integrity.
He is an optimist though his answer is conditional: “In
order to reconcile the growth that we would like to see with the ecological
realities of planet Earth, we are going to need the world economy to develop in
a fundamentally different way in the future” (p. 199). As practical examples,
he addresses the energy and food issues.
There are already powerful low-carbon energies available at
sharply declining prices, and more of them will come, he states. Just as we
need to find a new energy pathway based on energy efficiency and low-carbon
energy supplies, we also need to find new farm systems adapted to local
ecological conditions and causing less ecological damage. The end result from
these and other examples would be to “decouple” growth from resource use and
environmental impacts.
However, seen globally, “resource decoupling” and “impact
decoupling” are just not happening yet, additionally there are still the
population dynamics and even small changes of fertility rates would have big
effects on outcomes; according to the UN data, the medium-fertility variant
reaches 10.8 billion people by the year 2100. (p. 208).
Chapters 7 to 11 are on such complex topics as social
inclusion, education for all, health for all, food security, and resilient
cities. They make interesting reading, are well documented by statistical
details, and in a special way focus on the role the UN is playing.
Declarations, covenants, the Millennium Development Goals (MDGs) and present Sustainable
Development Goals, SDGs are looked at, showing the richness of global thinking
and action, as well as the successes and the deficiencies in various fields.
Presently, more than 50 percent of the human population
lives in cities, and urbanization is growing fast. What makes a city
sustainable, green, and resilient has not only become an important research
issue but is also of great importance to all those who leave the countryside
for cities.
Smart infrastructure is a major issue, and so are water
supply and waste management. Sachs presents examples that show how important urban
resilience has become as a political issue.
In the following chapters Sachs becomes an environmentalist:
i.e. in chapter 12, he refers to the basic science and the consequences of
human-induced climate change, to the mitigation of greenhouse gas emissions and
the adaptation to climate change, and to the politics of “decarbonisation”.
Saving biodiversity and protecting ecosystem services are in
focus in chapter 13: biodiversity in general is under stress, and so are
forests and oceans in particular. Sachs uses the threatening word “sixth great
extinction” to indicate what may be at stake. No wonder then that he turns to
the international dynamics that have been started - from the UN Convention on
Biological Diversity to the various implementation protocols to that treaty.
In his remarks on SDGs (chapter 14) he mentioned that “the
world is far off course for achieving sustainable development” (p. 481) -
that’s the disturbing kick-off of Sachs, the analyst. Sachs, the political
economist however presents a stimulating impulse: “the call for SDGs is a
historic decision, a powerful way to move to a new global agenda …The SDGs will
be universally applicable: the United States, just like Mali, needs to learn to
live sustainably” (p.484/5).
Is sustainable development feasible? This is the title of
the last sub-chapter in Chapter 14. Can we elaborate SDGs and carry them out in
time? This is the last question.
Sachs quotes three great global thinkers who have expressed
serious doubts: Jane Jacobs, the urbanist who called her last book “Dark Age
Ahead”; the astronomer Lord Martin Rees and his book “Our Final Century”; the
inventor of the Gaia theory, James Lovelock and his recent book “The Revenge of
Gaia”.
But Jeffrey Sachs himself is an American, and he thus
concludes in a typical way: “Sustainable development is the greatest, most
complicated challenge humanity has ever faced” (p. 506); and continues: “We
must not give up hope … I believe that despite the cynicism, the darkness, the
confusion, and the miserable politics on many of these issues, we can make a
breakthrough … The most important message I would (like to) send is that ideas
count” (p. 507).
Jeffrey D. Sachs’ book is a comprehensive, incisive,
well-illustrated and highly valuable book – a true must-read. It is full of
great ideas and practical suggestions. However, with 560 pages it may be too
voluminous to become the most read book on sustainable development. A condensed
edition should therefore be produced in order to reach more people, if not each
and every one, as the UN Secretary General so vividly requested.
