An impressively cohesive multidisciplinary overview of the opportunities and challenges associated with Africa’s largest dam.

edited by Zeray Yihdego, Alistair Rieu-Clarke and Ana Elise Cascão, The Grand Ethiopian Renaissance Dam and the Nile Basin, Earthscan, 2018, 224 pp.

In 2011, Ethiopia announced plans to construct the Grand Ethiopian Renaissance Dam (GERD) on the Blue Nile, one of the two main tributaries of the Nile River. Once complete, this hydroelectric dam will be the largest in Africa. The news was met with alarm from Sudan and Egypt, the two countries immediately downstream, which rely heavily on the Nile. Over the past seven years, the three countries (Egypt, Ethiopia and Sudan) have been engaged in negotiations in an effort to meet their individual and collective interests while mitigating potential risks. As is the case with most transboundary problems, the issues are complex and without simple solutions. Rarely do you see this type of complexity adequately described.

The Grand Ethiopian Renaissance Dam and the Nile Basin, however, is unique in successfully presenting this kind of complexity from multidisciplinary lenses in a cohesive way. Each chapter is (co-)authored by scholars who are actively engaged in the Nile River Basin or in transboundary water management and are experts in their respective fields. Presumably by design, the arc of the book flows seamlessly from describing the historical legal context (Chapters 2, 3 and 4) into the current sociopolitical context (Chapters 5 and 6), before switching to a future-oriented view of the potential economic impacts of the dam (Chapters 7 and 8) and options for the filling and operation of the dam (Chapters 9 and 10).

Remarkably, despite switching from one disciplinary lens to another, the authors manage to maintain a fairly consistent set of messages. The introductory chapter outlines eight major themes of the book, but three are particularly important. First, the construction of the Grand Ethiopian Renaissance Dam and the resulting engagement of the three Eastern Nile countries represents a significant shift in the hydro-politics of the Basin. One shortcoming of the book in this regard is that it nearly unequivocally supports the dam and the upstream countries in challenging the “status quo” of water use in the Nile Basin. This is problematic because the advocacy varies in strength from chapter to chapter, without ever being explicitly addressed or explained. The analysis may seem one-sided to anyone unfamiliar with Nile Basin dynamics, especially as described in the first half of the book.

Second, the book emphasizes the potential benefits that each country stands to gain from the operation of the GERD. These benefits are described from multidisciplinary lenses: e.g., more equitable water use throughout the basin (law); enhanced regional cooperation (politics); catalyst for regional economic growth (economics); and improved water management functions along the Blue Nile (hydrology). Relatedly, the third message of the book is the urgent need for continued cooperation. The GERD has been politicized, arguably by all three countries of the Eastern Nile (and by many others), and is often characterized as a source of conflict. This book challenges that framing by emphasizing the potential gains that can be realized through cooperation.

With a little more work, perhaps in the introduction, the editors could have contextualized the story a bit more. Also, in ending with a chapter on managing risks (rather than a proper conclusion), they missed a valuable opportunity to clearly enumerate the “implications for transboundary water cooperation” (as suggested in the book’s subtitle). Finally, they could have explained more explicitly why an interdisciplinary approach to analyzing such complex problems is so challenging, rare, invaluable and increasingly necessary.

This is an excellent book for anyone interested in Nile Basin developments because it presents the current challenges, potential opportunities and issues that need to be resolved before the GERD becomes operational.

by Jeremy J. Schmidt, Water: Abundance, Scarcity and Security in the Age of Humanity, SAGE, 2018, 307 pp.

Cape Town may be the first waterless city, but the fact that humans are drawing more than their fair share of water should make us shudder as things are likely to become worse before they get any better. From surplus to scarcity, human interference with global water systems has created an issue of security, requiring new ways of managing water in the age of the Anthropocene. With the idea of water stability thrown into a tailspin, there is an urgent need to define “safe operating space” for humans to work within planetary boundaries for sustaining life and life forms.

By altering planetary systems, humans have attained the status of a geological force, causing all the ways in which water management connects to geography, culture and economics to lose their relevance. Far from inducing equitable access to water across sectors, the global impact of the American approach to water management has triggered a brazen water grab not only within the local hydrological contexts, but also in regional and national contexts. Unless this prevailing approach is questioned, argues Jeremy Schmidt, inequalities, including those that exist on a geological scale, cannot be addressed.

While it should be apparent that dividing humans from nature will not help us understand our impact on natural processes, a failed attempt to reject the society/nature dualism in the past had led to an oppressive logic and enhanced the prospects of meeting certain ends rather than others. The book asks: how do conflicts over water, such as those over the right to water, gain prominence?

The trouble with a single planetary story about water, especially one tied to a techno-centric philosophy of water management, is that while it does not deny that alternatives exist, it simply posits that we can get by without them. Schmidt presents three philosophical perspectives to counter this view: first, water resources should be managed without privileging a particular cultural understanding; second, we should acknowledge that social relations take shape around different water use practices; and third, we should appreciate and acknowledge the intrinsic importance of different symbolic ends that others attach to water. These three concerns—over subjects, social relations and symbolic goods––could be critical entry points for initiating a new discourse on water management. We need this because the paradigm of “making things public” is inadequate; it fails to see that water problems are the outcome of a failed nineteenth-century solution tied to society/nature dualism. Although this argument may seem troublesome to those excited about emerging social entrepreneurship around water, Schmidt is asking us to consider the questions that arise for modernity as the result of water management practices instead of thinking about water management as the product of modernity.

Relying on volumes of historical sources, the book attempts to bridge engineering solutions and the social ideas that informed them. As we are now part of an “unfolding water drama,” the challenge for global water governance is that it has not separated itself sufficiently from the philosophy that gave rise to the problems it seeks to solve.

 Schmidt does not offer a solution, but rather questions the prevailing philosophy of water, the end result of which is that water, once abundant, is now scarce.  If water continues to be managed as it is at present, the majority of our rivers will only be carrying treated waste water.

Water offers refreshing new historical and philosophical insights to help rethink the prevailing (global) philosophy of water management.

To be on cloud nine!

by Richard Hamblyn, Clouds: Nature and Culture, Reaktion Books, 2017, 240 pp.

From the realm of literature and arts to the domain of astronomy and science, clouds have emerged from a muddle of uncertainty into the world of scientific certainty in the context of climate change. Capturing their picturesque journey from “an ultimate art gallery above” in the words of Ralph Waldo Emerson to the “center of digital life below” as propounded by Steve Jobs, Richard Hamblyn provides a multifaceted narrative about nature’s most versatile creation. Packed with colorful pictures, Clouds could easily be the most comprehensive and authoritative text on the subject to date.

Hamblyn, an English lecturer at the University of London, has attained undisputed mastery of the subject, having already published two other books on clouds–– The Cloud Book and Invention of Clouds. While the first captures everything to do with the origin and development of clouds, the second is a cultural excavation of our understanding of the science of clouds. In this third book, Hamblyn has brought clouds down to earth and unveiled some of their mystery. Throughout human history, attempts to understand clouds and their behavior has been a subject of delight and fascination, offering limitless opportunities for creative contemplation.

Clouds is a magnificent collection of these stories – from their wooly journey through art, literature, music and photography to their sinister manipulation for military use and anthropogenic modification. (Failed) American attempts at precipitating flash floods during the Vietnam War are part of the legend. Such secret military efforts have invoked widespread prompting by the international community to declare clouds as “a resource that belongs to no one.” Legal remedies for appropriating clouds through artificial seeding may be needed as competition over access to rainwater escalates.

Science is only beginning to understand the role that clouds play in shaping future conditions on earth––a warm atmosphere may reorganize the day-to-day behavior of clouds in ways that could either amplify or mitigate climate change. The trouble, warns Hamblyn, is that clouds have a habit of behaving in complex and surprising ways. The fact that our warming climate is producing ever more lightning strikes is one of many such surprises. Each 1 degree rise in temperature increases lightning activity by around 12 per cent. Will clouds turn out to be agents of global warming or will they end up saving the day by reflecting ever more sunlight back into space?

Clouds challenge human intelligence. Philosophers like Aristophanes have long professed that “from clouds come our intelligence, our dialectic and our reason; also, our speculative genius and all our argumentative talents.” Wondering if clouds were objects or phenomena or processes, Leonardo da Vinci described them as formless triggers of visual invention, their fleeting magnificence and endless variability providing food for thought for scientists and daydreamers alike. Our current predicament with clouds is taking us back in time to reimagine and reunderstand them. There may be clues in art and literature to help us make a fresh beginning!

Hamblyn contends that the law of unintended consequences needs to be kept in mind when embarking on geo-engineering projects aimed at tampering with the atmosphere and with clouds. Clouds are too sensitive not to be taken into account in such anthropogenic adventures, he cautions. In short, there is no way of knowing what will happen to our rapidly changing atmosphere.  Just as in centuries past, when clouds were employed as ready metaphors of doubt and uncertainty, it looks as if they will continue to be so for centuries to come.

The crucial issue is that life without clouds would not be physically possible. Far from just being a source of water, they have a larger role to play in keeping the earth hospitable for living beings. Clouds provides insights into the history and science of clouds, and offers guidance regarding the sensitive handling of the woolly product/process hovering between the sky and earth. Colorfully illustrated, this is the ultimate guide to the past, present and future of clouds.

While the United States may have leveled off its water use to 1970 levels, in spite of both population and economic growth, the health of its rivers continues to remain a concern.

by Sean W. Fleming, Where the River Flows: Scientific Reflections on Earth’s Waterways,  Princeton University Press, 2017, 216 pp.

Its global prevalence notwithstanding, the state of water in nature reflects our inadequate understanding of its intricate flow dynamics. Despite its abundance, access to water eludes millions of people, and the stress on the ecosystems involved continues to grow. More than one billion people lack access to clean water, and in the near future, the global demand for water will be twice what it is now. With no substitute for this life-nurturing fluid, it is more important than ever that we ask the right questions so we can get past the current muddle.

All rivers are alike in the broadest sense, but they have different meandering curves, diverse aquatic fauna and distinct morphological features. Unraveling this distinctiveness and the (unknown) variables that contribute to it are the challenges that confront hydrologists. Existing watershed models are insufficient. Indeed, many of the best modelers don’t rate their results too highly. Part of the problem, in the words of Belgian Nobel Laureate Ilya Prigogine, rests on our innate desire to simplify complexity. Unfortunately, reducing elaborate systems into simpler subsystems doesn’t necessarily help: we end up learning more about less. Such an approach is particularly unhelpful when we are trying to understand river hydrology. The uncertainty involved is a function of a great many environmental and social factors that shape stream flow and underlying aquifers.

Sean Fleming’s Where the River Flows calls for a paradigm shift. He favors a radical departure from the usual disciplinary thinking; indeed, since rivers are a reflection of the profound interrelationships between landscapes, ecosystems and societies, no disciplinary perspective can adequately address their complex dynamics. He believes that fractal mathematics along with chaos and information theory can be used to generate new insights into the overall patterns of river systems. As anthropogenic impacts on the natural environment (like climate change) accelerate, there is a need for both finer detailed forecasts (e.g., will my farm get rain next week?) and big picture understanding (e.g., will the river topple its banks this coming season?). New insights in both dimensions are critical to understanding the common but differentiated patterns that each river generates in its unique geomorphological setting.

Unfortunately, a counter narrative persists, making it harder to get a better sense of river hydrology. Damming, diversion and contamination pose formidable challenges, beyond the normal ecological complexity, to figuring out how to sustain healthy stream flows for human welfare and ecosystem survival. Be it the Mississippi, Ganges or Yangtze, river degradation has thrown off balance the delicate equilibrium between ever-increasing human populations and their relentless aspiration to stay adequately watered. The United States may have leveled off its water use to 1970 levels in spite of both population and economic growth, but the health of its rivers continues to remain alarming. While every drop of water pumped from the Colorado river is used at least 17 times, which may sound like good news, the net impact of all that pumping on the Gulf of California has grossly disrupted the hydrological cycle. River water hasn’t reached the delta since 1960.

Fleming calls for an entirely new way of viewing the natural environment, suggesting that we need to process vast and complex information to reconceptualize and understand the dynamics of the natural environment. But can reams of hard data and new quantitative modeling techniques give us a better sense of river systems that are not only dynamic but also living entities? As the need for more accurate, precise and consistent forecasts move center stage in our dealings with the rivers, somehow cultural perspectives must also be included. It is not clear how we can convert human observations into actionable information.

The emergence of and reactions to environmental litigation in China.

by Rachel Stern Environmental Litigation in China: A Study in Political Ambivalence, Cambridge University Press, 2013, 314 pp.

What happens when tons of industrial waste are dumped in a Chinese river? Rachel Stern’s insightful book Environmental Litigation in China: A Study in Political Ambivalence explores the shifting conditions under which the Chinese legal system is being used to address pollution issues. While the book is written in clear and accessible prose, it complicates common narratives around the Chinese legal system and exposes its many contradictions. The first half of the book provides a nuanced picture of environmental litigation including exploring specific pollution cases with different approaches and outcomes and is fascinating as it reveals the strengths, limitations and creativity within environmental litigation. The second half of the book analyzes the issue from the perspectives of judges, lawyers and NGOs. While the voices of state actors are notably absent, given the limitations of research in China this is understandable. Stern rallies a range of evidence to support her argument.

She demonstrates how actors are reacting to a state that sees the advantages of using the law to control pollution, but also recognizes how the law could undermine the state itself. Stern terms these conflicting state signals political ambivalence and analyzes how they provide space for bottom-up experimentation and incremental change. It is, however, also clear that the legal system alone will not be enough to address the variety of forces that allow pollution to continue.

The book focuses on the Hu period and should be taken as a slice in time. The legal landscape is changing as the new environmental law makes it easier for some groups to sue polluting industries. The first public interest case under the new law in 2016 was successful. Most cases, though, are still not making it to the court. The book would be a great choice for an undergraduate or graduate course on environmental politics. It is also likely to engage anyone interested in the intersection of law and the environment.
