Combining land use and water management objectives is the key to sustainable development

Water – its Control and Combination: Multifunctionality and Flood Defences, by Monica Altamirano, Rik Jonker, and Jurgen van der Heijden, Osborne/Deltares, June 2013 (Google the title for free download of the recent English version)

A road on a dyke with sheep on the slope beside it. Can this age-old combination inspire the development of modern flood defenses? Think of dykes producing renewable energy, or serving as nurseries for new plantlife. A good reason to make combinations like these is their sustainability. Three Dutch experts present and analyse a collection of almost thirty examples, mostly from the Netherlands. Although meant as a factual report, this book puts forward a message deserving extra thought.

An area is set aside for water storage to prevent flooding of a nearby city. This area is also a place for nature conservation, water treatment, open city and recreation. Developing and using the same land for multiple purposes saves space, time and money. Yet, however interesting, this isn’t what makes these combination special.

Authorities are used to optimizing each function separately; for instance, creating a basin for water storage as wide and deep as possible at the lowest possible cost. Combining functions sharing can bring the cost down, but what is special is how multiple functionalities can optimize one another. Water storage helps nature, and nature helps water treatment. Such combinations enhance spatial quality, resulting in a better place for recreation. Revenues from recreation can be devoted to nature conservation.

Using one function to optimize others provides a unique economic force that has always been there, but has yet to be fully explored. The authors prove with almost thirty examples that such an approach contributes to sustainable development. This is an inspiring book for water managers who want to go beyond traditional solutions.

Replacing costly minerals with cheaper ones is the key to sustainable mining

Extracted: How the Quest for Mineral Wealth is Plundering the Planet, by Ugo Bardi, Chelsea Green Publishers, 2014

The Club of Rome shot to fame with publication of The Limits to Growth in 1972. This report on the future of mankind not only triggered a hot debate, but degenerated in all-out smear campaign. By the time its critics had had their say, the public perception of the report was that it offered nothing more than a series of wrongheaded predictions made by a group of deluded scientists. So much so, subsequent reports by this global think tank have not merited much attention.

Extracted is the latest report from this elite club. Had The Limits to Growth attained popularity, the title of this report could easily have been The Limits to Extraction. Digging out the history of mining, from prehistoric times to the modern age, the report suggests that mankind has extracted most of the cheap mineral resources available while plundering of the earth’s ecosystems and displacing millions of people. Mining is one of the largest global industries, but the gradual depletion of low-cost minerals, including fossil fuels, is fast becoming a major limitation to economic growth. Since high-grade ores are extracted first, it will become much more expensive to produce mineral commodities in future. Given the growing demand for precious metals and rare earths, however, a resource war is likely to emerge among countries that hold quasi-monopolies over certain mineral deposits.

The political economy of mining makes it an important growth engine for most countries. China has 97 per cent of all active rare earths, including exclusive deposits of molybdenum. South Africa holds 82 per cent of global platinum. China leads countries like Chile, Australia and Argentina in global copper output. Tibet has become the new mining focus for China. Under a new regime, India intends to go full throttle into mineral extraction.

Extracted is written by a team of experts, headed by Italian scientist Ugo Bardi. The report says that deposits of many high-grade ores are running low: copper, zinc, nickel, gold, silver and others are expected to reach their productive peak within less than two decades. Not only will this affect our lifestyles, but it may cause agriculture production to decline as well. By the time the world wakes up to the full impact of mining (including oil and gas), the lasting impacts may be impossible to reverse.

The solution, says Bardi, is to replace costly minerals with cheaper ones; recycle as much as possible, and generate energy through renewable energy sources such as sun, wind and water. He and his colleagues believe that mining machines and drilling rigs will disappear without a corresponding decline in the demand for minerals.

Virtual field trips to see ecological restoration make this a special book.

Ecological Restoration: Principles, Values and Structure of an Emerging Profession, by Andrew F. Clewell and James Aronson, Island Press, 2nd edition, 2013

The premise behind this exhaustive account of the practice of ecological restoration is to illustrate the Pandey (2002) concept of “holistic ecological restoration” in great detail. Restoration in this context focuses as much on socioeconomic considerations as it does ecological concerns. As is true in most interdisciplinary efforts of this sort, sustainability and biodiversity conservation are bundled with restoration in a complex fashion, creating somewhat uneven results. Though careful, detailed, and thorough, this volume seems at times to be trying to do too many things. A number of the key concepts mentioned probably warrant primers of their own. Hints of this problem surface in the early sections which offer a seemingly unending list of potential members of a target audience for the book that could, in effect, include anybody. Efforts to appeal to such a wide audience blur the focus. Any hope of an integrated examination of the socioeconomic and biophysical steps crucial to restoration is lost.

The authors note that their intent is not to provide a comprehensive review of scholarship in the field, but they ignore decades of careful scholarship that might have helped to ground what they call “an emerging profession.” All that being said, the book has a number of redeeming qualities, especially the “Virtual Field Trips” or illustrated case examinations of specific restorations. These are different from other practice-oriented restoration presentations in other texts in terms of the range of ecosystems covered and the variety of case locations, which span the globe. I would use this text in an introductory course on ecosystem-based management or sustainable development.

Managing ecosystems services can reduce poverty.

Ecological Economics from the Ground Up, edited by Hali Healey, Joan Martinez, Leah Temper, Mariana Walter and Julien-Francois Gerber, Routledge, 2012

and

Nature’s Wealth: The Economics of Ecosystem Services and Poverty, edited by Pieter van Beukering, Elissaios Papyrakis, Jetske Bouma and Roy Brouwer, Cambridge University Press, 2013

The popularity of the “ecosystem services” concept continues to grow. Recently, two new edited volumes were added to the seemingly ever-expanding library of books describing the benefits that nature provides to people. Both publications follow the same general structure: offering a broad introduction to the idea of ecosystem services, followed by a series of in-depth case studies from all over the world. Perhaps surprisingly, this is where the similarities end.

The examples in Nature’s Wealth: The Economics of Ecosystem Services and Poverty are organized around concerns like biodiversity, marine and coastal ecosystems, and forests. The central hypothesis of the book is that the protection or restoration of ecosystem services is likely to alleviate poverty. Most of the case studies in Nature’s Wealth indicate that environmental protection, like the creation of Marine Protected Areas, can reduce poverty in a variety of ways. This kind of analysis, it turns out, doesn’t really need to dig into the ecosystem services concept at all. In fact, in the chapter on marine protected areas in the Asia-Pacific, ecosystem services are hardly mentioned. This is troublesome. An increasingly pressing question is whether using the concept of ecosystem services is helping to inform better resource management practices or not.

As Antunes et al. write in their introduction to Ecological Economics from the Ground Up, “The value commitment to work for a sustainable society has always been a distinctive feature of ecological economics as a scientific discipline” (p. 2). Or, to put it differently, the goals of the proponents of the ecosystem services concept have never been purely academic. So, while an ever-increasing number of publications using the ecosystem services concept indicates popularity among scholars and researchers, some of the original proponents have expressed concern that the practical goals associated with the concept have yet to be achieved. It has been more than five years since a group of prominent scholars argued that it was “time to deliver” (Daily et al. 2008). Since then, one of the early proponents of the concept has lamented that ecosystem services has gone from being “an eye-opening metaphor to a complexity blinder” (Norgaard 2010).

The book Ecological Economics from the Ground Up represents an original, useful and accessible examination of how the explicit use of the ecosystem services concept can inform environmental decision making in practice. For example, the introduction includes an extensive table of environmental advocacy organizations showing how they use ecosystem services concepts and methods. The remainder of the volume places the goal of working towards sustainability at it center. The writers of many of the cases are environmental activists directly involved in the conflicts they describe. This approach does not always yield the most even-handed accounts, but it does provide a detailed sense of how specific ecosystem service-based concepts and methods have been used to influence decisions. More disinterested (but certainly not uninteresting) explanations of key concepts and methods appear in text boxes throughout what are often deeply controversial cases. In the most successful chapters, this provides a rich account of how concepts and approaches drawing on the ecosystem services idea can influence environmental decision making in practice.

In summary, both of these books contribute to the environmental literature. Nature’s Wealth seeks to empirically test the hypothesis that environmental protection alleviates poverty under a variety of conditions and in different ecosystems. Since this assumption has come to be almost taken for granted in some quarters, this is a meaningful scholarly endeavor. However, this project is in some ways only tangentially related to the concept of ecosystem services. Ecological Economics from the Ground Up, on the other hand, is less scholarly and limited in its ambition to test specific hypotheses. It is a truly exciting and innovative contribution to the literature on ecosystem services.

An important and well-documented book. A very helpful guide to sustainable development and sustainability science.

Sustainability Science, by Bert J. M. de Vries, Cambridge University Press, 2013

This book provides one of the best explanations yet of the origins and meaning of sustainable development. Quoting Seneca (3 BC – 63 AD), de Vries writes: “The society of man is like a wall of stones, which would fall if the stones did not rest on another; in this way it is sustained.” The book puts the problems of sustainable development in context, providing case examples, discussing the trajectory the concept has taken to reach the current moment, and highlighting the thinking behind it.

The book clearly states that a scientific worldview by itself cannot give meaning to our lives; nor can it resolve the ethical questions surrounding sustainability. Sustainability science has a more limited scope than sustainable development. Essentially, it is the study of what science can and cannot know. Even if thermodynamics, system dynamics and complexity theory are designated essential components of sustainability science, and it is based on the premise that studies of real-world problems must not respect the confines of artificial nineteenth-century boundaries among scientific disciplines, sustainability science can only illuminate part of what we need to know. Current complexity and uncertainty require a realistic appreciation of the predictive and explanatory powers of science and models.

Questions regarding what we ought to do are outside the scope of sustainability science, although the book opens up a panorama of possible directions we might take, offering multiple options for reflection and discussion. The discussion of sustainable development should be required reading for all university students. The section on sustainability science is much more demanding and is only suitable for students at an advanced level with strong science background. An experienced teacher prepared to jump between traditional disciplines would do well to incorporate this book into his or her classes.

The author focuses on renewable and non-renewable resources as well as the essentials of earth, land, nature and agro-industrial systems. At the end of each chapter, there are relevant book references and websites. The best news is that book has been “field-tested” for seven years. I highly recommend it.
