A World of Rivers: Environmental Change on Ten of the World's Great Rivers, by Ellen Wohl

Far from being the serene, natural streams of yore, modern rivers have been diverted, dammed, dumped in, and dried up, all in efforts to harness their power for human needs. But these rivers have also undergone environmental change. The old adage says you can’t step in the same river twice, and Ellen Wohl would agree—natural and synthetic change are so rapid on the world’s great waterways that rivers are transforming and disappearing right before our eyes.

����������� A World of Rivers explores the confluence of human and environmental change on ten of the great rivers of the world. Ranging from the Murray-Darling in Australia and the Yellow River in China to Central Europe’s Danube and the United States’ Mississippi, the book journeys down the most important rivers in all corners of the globe. Wohl shows us how pollution, such as in the Ganges and in the Ob of Siberia, has affected biodiversity in the water. But rivers are also resilient, and Wohl stresses the importance of conservation and restoration to help reverse the effects of human carelessness and hubris.

����������� What all these diverse rivers share is a critical role in shaping surrounding landscapes and biological communities, and Wohl’s book ultimately makes a strong case for the need to steward positive change in the world’s great rivers.

A World of Rivers
By Amazon Customer
Ellen Wohl's A World of Rivers gives a fantastic and in depth introduction to understanding the world's greatest rivers and the effects of human interactions with them. She divides the book into twelve chapters and covers the ten greatest rivers in the world: The Amazon, The Ob, The Nile, The Danube, The Ganges, The Mississippi, The Murray-Darling, The Congo, The Chang Jiang, and The Mackenzie. There is also an introductory and conclusive chapter that both illustrates the importance of these rivers and gives an easy-to-read style that explains the contents of the book very succinctly. She also separates the chapters by inserting a creative interlude taking an artistic form. They all tell the epic journey a water droplet takes to get from the mouth of the Amazon to the Atlantic ocean or from the mouth of the Nile to the Mediterranean Sea, etc. Ellen Wohl's book is a fun and informative read, letting the reader know just how much to know in order to have a basic understanding of the world's great rivers and human impact thereon.
Wohl states her purpose early on in the introductory chapter as to "explore how the changes humans impose can impoverish the rivers, and by extension impoverish all the many creatures that rely on both of them." She goes on to explain that of the ten rivers covered only three remain relatively untouched by humans and the other seven are "undergoing rapid change" (Wohl, p. 2). From the first sentence of each chapter does the information start flowing from the page. There are no pointless introductions or meaningless paragraphs that drag on, but rather she exemplifies the rivers by describing them very concretely. The chapter in which she describes the Amazon is a wonderful sample of how she writes about the rivers and their components. She illustrates that the Amazon watershed stretches from the wester shoreline of the Pacific Ocean all the way to the eastern shoreline of the Atlantic Ocean and is the largest watershed in the world.
In her chapter on the Nile the entire fluvial process is elucidated, starting from the mouths of both Lake Victoria and Lake Tana (the beginning of the White Nile and the beginning of the Blue Nile). Covering every aspect of the hydrologic cycle in both the White and Blue Nile and then continuing once they convene, Wohl shows the reader exactly the comfortable proportion of facts and narration to make these sections easy to read.
The book as a whole is a wonderful initiation into the study of fluvial systems in the world and holds a multitude of information on the world's ten largest rivers. The message is conveyed in an easy to follow style and the fact-based information is happily coupled with integrating interludes that take a more creative look at the chapter covered prior. The book's main point, the human's impact on the rivers, is shown throughout each chapter even if the river still remains for the most part untouched and leads the reader to follow up with her thesis by sparking a sense of curiosity in the reader and a desire to travel to these far off places of beauty which has been subject to so many a poem.
However, as the book is targeted towards the ten biggest rivers in the world it may not speak as passionately to some as the content does not touch upon the smaller fluvial systems that may be closer to home. This is hardly a large diminishing factor in the overall quality of the work, but merely a side note and spoiler that some may be expecting upon reading the book.
This is a fantastic volume on the world's largest fluvial systems that should be in the bookshelves of each who studies or has some sort of interest in the rivers that host such beautiful parts of the natural world.

Not all the world of rivers but a good start
By lyndonbrecht
Wohl uses the writerly device of the migrations of a drop of water through these systems. I don't think it works particularly well, although it does make the point that world rivers are part of a vast system of water flows over and under and through the land.

She has useful detail on river dynamics and rivers in a general sense. The strength of the book is the detail on each river, allowing a sort of compare and contrast of the past and the present situation of each. The ten rivers are by no means all of the most important, but exemplify all the others. Each has things unique to its history--the Ob faces pollution from nuclear waste from the former Soviet Union's weapons programs, the Ganges features a reverential kind of pollution from cremations on its banks, the Mississippi has been altered almost beyond recognition by the Army Corps of Engineers. The context and situation of each river would be a book to itself, but Wohl manages to provide significant context and does it readably. The environmental changes she describes include in particular, dams.

I found the chapters on the Amazon and the Congo to be the most interesting, because of my interest in Brazil and the Congo. Other readers may differ. Rivers worldwide are worth finding out about, particularly as water becomes scarce. Future conflicts are likely to emerge over the Nile (between Egypt and Ethiopia), the Tigris and Euphrates (Turkey and Iraq), the Colorado (USA and Mexico) and Chinese interest in Siberian waters. Her book covers only ten of many important rivers, but it is a very good start for anyone interested in rivers. Look at a map and see which major rivers in Southeast Asia originate in China, and you'll see why rivers may be sources of conflict.

A world of rivers
By Ekezimero Eto
A World of Rivers, by Ellen Wohl. Chicago: University of Chicago press, 2011, 359pp.
A World of Rivers was written by Ellen Wohl, a professor of geosciences at Colorado state university. The book explores ten of the world largest rivers: (Amazon, Congo, Chang Jiang, Mississippi, Ob, Danube, Mackenzie, Ganges, Nile, and Murray-darling). Each chapter focuses on the 10 different rivers. He explores the natural history of the world's largest rivers that are listed above and the history human alteration to these river ecosystem by reading on a journal down each river and along the pathways that connect seemingly far distant rivers. Although he explores the approach of environment historians, he did not explore the social history of the people living in each of the river basin. I think if he explored the social history it would have explained more how the people of those regions harmed the river and in the long run the disadvantages are terrible.
The author emphasizes the interconnectedness of everything in the environment through examination of the history of rivers in order to encourage people to be more respectful of the rivers and the environment in general. The author gave some examples of how the River flow through many channels and when they overtop their banks, the water flows, carrying sediment and nutrient that rejuvenate the wetlands and the forests of the floodplain. There is a saying that a river does not flow through the forests without bringing down or taking along things like trees and soil. The soil and all the things that flow with the rivers, which provide food and nursery habitat for vulnerable young fish and the floodwater pass through different channels, carrying organic matter that helps supply the river's food web. The author identified the flowing of river as "flood pulse" as one of the primary contributors to river health. Learning about the rivers you end up learning about different things that go on in the environment.
The author makes connection between how humans have harmed the rivers and how that will, in turn, harm humans. Regardless of the resource supplied and the vital service from the River, human activities have impoverished most of the world largest river basins. The dam is one of the examples of human impoverished activity, out of the ten largest rivers in the world; five have been affected by the dam (Mississippi, Nile, Danube, Change Jiang and Murray-darling), are strongly affected catchment in which the main channel and tributaries are highly fragmented by dams that affectively break the channel up into shorter segments. Only 120 of the 292 catchments assessed for the study were judged to be unaffected as a result of fragmentation or flow regulation by dams and most of these are smaller rivers.
The author reviews the ten rivers to show how each has its own unique identity and place in the world. In each of the river the author talk about the precipitation, windblown sediments and the atmospheric contaminate enter them from the air. Chapter 2 talk about the precipitation over the headwater of the amazon, following the river downstream across south America and chapter two ended where the Amazon enter the Atlantic, she explain this by tracing the pathway of a hypothetical water droplet leaving the mouth of the Amazon until the droplet falls as precipitation on the headwater of the Ob-Irtysh river system in Siberia. In each succeeding chapters follow the same format as in chapter 2, tracing the path of the same water droplet down another river basin and then follow it to the next one. In each chapter the author trace the pathways between rivers basin and she tried to estimate realistic rates of travel for a droplet moving with Specific Ocean current and the atmospheric circulation patterns.
In conclusion the book was able to explore that the world is part of one round river giving example. Like the things the people in the United States do to the Mississippi river basin does make a different in the basins of the Congo, the Ob-Irtysh and the Murray-darling and vice versa. The author uses the ten great rivers as pathways of learning and exploration of rival all over the world. The book is written to non-specialist readers interested in natural and environmental history and the book provide some reference material for those who wish to delve further into the topics discussed. I will end up saying that we can claim ignorance of the effects of our action and we are all part of one round river.
