Book Description
Water quality concerns are not new to the Great Lakes. They emerged early in the 20th century, in 1909, and matured in 1972 and 1978. They remain a prominent part of today's conflicted politics and advancing industrial growth. The Great Lakes Water Quality Agreement, under the Boundary Waters Treaty of 1909, became a model to the world for environmental management across an international boundary. Evolution of the Great Lakes Water Quality Agreement recounts this historic binational relationship, an agreement intended to protect the fragile Great Lakes. One strength of the agreement is its flexibility, which includes a requirement for periodic review that allows modification as problems are solved, conditions change, or scientific research reveals new problems. The first progress was made in the 1970s in the area of eutrophication, the process by which lakes gradually age, which normally takes thousands of years to progress, but is accelerated by modern water pollution. The binational agreement led to the successful lowering of phosphorus levels that saved Lake Erie and prevented accelerated eutrophication in the rest of the Great Lakes ecosystem. Another major success at the time was the identification and lowering of the levels of toxic contaminants that cause major threats to human and wildlife health, from accumulating PCBs and other persistent organic pollutants

Book Description
The Great Lakes are the largest collection of fresh surface water on earth, and more than 40 million Americans and Canadians live in their basin. Will we divert water from the Great Lakes, causing them to end up like Central Asia's Aral Sea, which has lost 90 percent of its surface area and 75 percent of its volume since 1960? Or will we come to see that unregulated water withdrawals are ultimately catastrophic? Peter Annin writes a fast-paced account of the people and stories behind these upcoming battles. Destined to be the definitive story for the general public as well as policymakers, The Great Lakes Water Wars is a balanced, comprehensive look behind the scenes at the conflicts and compromises that are the past-and future-of this unique resource.

Book Description
As the new chief of the Michigan Department of Conservation’s Fish Division in 1964, Howard A. Tanner was challenged to “do something . . . spectacular.” He met that challenge by leading the successful introduction of coho salmon into the Michigan waters of the Great Lakes. This volume illustrates how Tanner was able to accomplish this feat: from a detailed account of his personal and professional background that provided a foundation for success; the historical and contemporary context in which the Fish Division undertook this bold step to reorient the state’s fishery from commercial to sport; the challenges, such as resistance from existing government institutions and finding funding, that he and his colleagues faced; the risks they took by introducing a nonnative species; the surprises they experienced in the first season’s catch; to, finally, the success they achieved in establishing a world-renowned, biologically and financially beneficial sport fishery in the Great Lakes. Tanner provides an engaging history of successfully introducing Pacific salmon into the lakes from the perspective of an ultimate insider.

Book Description
The stuff of nightmares in both their looks and the wounds inflicted on their victims, sea lampreys (Petromyzon marinus) are perhaps the deadliest invasive species to ever enter the Great Lakes. At the invasion’s apex in the mid-20th century, harvests of lake trout (Salvelinus namaycush), the lampreys’ preferred host fish in the Great Lakes, plummeted from peak annual catches of 15 million pounds to just a few hundred thousand pounds per year—a drop of 98% in only a few decades. Threatening the complete collapse of the fishery, the sea lamprey invasion triggered an environmental awakening in the region and prompted an international treaty that secured unprecedented cooperation across political boundaries to protect the Great Lakes. Fueled by a pioneering scientific spirit, the war on Great Lakes sea lampreys led to discoveries that are the backbone of the program that eventually brought the creature under control and still protects the largest freshwater ecosystem in the world to this day. Great Lakes Sea Lamprey draws on extensive interviews with individuals who experienced the invasion firsthand as well as a trove of unexplored archival materials to tell the incredible story of sea lamprey in the Great Lakes—what started the invasion, how it was halted, and what this history can teach us about the response to biological invaders in the present and future. Richly illustrated with color and black & white photographs, the book will interest readers concerned with the health of the Great Lakes, the history of the conservation movement, and the ongoing threat of invasive species.

Book Description
The first English-language publication of a major history of the Great Lakes region of Africa. Though the genocide of 1994 catapulted Rwanda onto the international stage, English-language historical accounts of the Great Lakes region of Eastern Africa--which encompasses Burundi, eastern Congo, Rwanda, western Tanzania, and Uganda--are scarce. Drawing on colonial archives, oral tradition, archeological discoveries, anthropologic and linguistic studies, and his thirty years of scholarship, Jean-Pierre Chr tien offers a major synthesis of the history of the region, one still plagued by extremely violent wars. This translation brings the work of a leading French historian to an English-speaking audience for the first time. Chr tien retraces the human settlement and the formation of kingdoms around the sources of the Nile, which were "discovered" by European explorers around 1860. He describes these kingdoms' complex social and political organization and analyzes how German, British, and Belgian colonizers not only transformed and exploited the existing power structures, but also projected their own racial categories onto them. Finally, he shows how the independent states of the postcolonial era, in particular Burundi, Rwanda, and Uganda, have been trapped by their colonial and precolonial legacies, especially by the racial rewriting of the latter by the former. Today, argues Chr tien, the Great Lakes of Africa is a crucial region for historical research--not only because its history is fascinating but also because the tragedies of its present are very much a function of the political manipulations of its past.

Book Description
The Great Lakes—containing one-fifth of the standing freshwater on earth, covering some 94,250 square miles with a combined 10,210 miles of shoreline—have suffered greatly from human use and abuse since the advent of the commercial fur trade in the late 1600s. Logging destroys or degrades habitats, urbanization and industrialization pour human and industrial wastes into the water, fertilizers flowing off farm fields feed algae that suffocate other creatures, and ships bring in exotic species that decimate the lakes’ biodiversity. In 1985 when the International Joint Commission identified more than forty pollution hotspots around the lakes, few people had faith the Areas of Concern would be cleaned up in their lifetime. Indeed, aquatic ecosystem restoration is extremely difficult: only nine of these hotspots have been removed from the infamous list. But progress is being made, and at the helm are local champions, people with a profound love of the region who lead by example and build broad, diverse coalitions in order to realize a common vision. The stories of fourteen of these champions are told here to inspire necessary action to care for the place they call home, so it may be a home to many living creatures for ages yet to come.
