Yam in West Africa

Food, Money, and More

Felix I. Nweke

Michigan State University Press, 2015

Yam in West Africa examines a crop that has been sidelined and ignored for too long while being central to the existence of so many and consumed worldwide. In this book, Felix Nweke attempts to unravel the contradictory nature of the yam crop sector in West Africa by looking at the largest issues in the problematic industry.

Yam production is concentrated in West Africa, which is responsible for more than 90 percent of the 50 million tons produced annually around the globe. Though the crop can attract high prices, too often its producers live in penury. Regional issues drive up labor costs of food crops because of dependence on obsolete technology. In addition, certain agronomic practices that are peculiar to yam production remain unchanged, and pests and diseases still ravage the crop. Yam in West Africa investigates solutions to these problems with the aim of expanding yam production, increasing sales, helping farmers, and bringing more of this staple food to those who need it. The future of the yam is bright; this book aims to make it more so.

Yellowstone Wolves

Science and Discovery in the World's First National Park

Edited by Douglas W. Smith, Daniel R. Stahler, and Daniel R. MacNulty

University of Chicago Press, 2020

In 2020, it will have been twenty-five years since one of the greatest wildlife conservation and restoration achievements of the twentieth century took place: the reintroduction of wolves to the world’s first national park, Yellowstone. Eradicated after the park was established, then absent for seventy years, these iconic carnivores returned to Yellowstone in 1995 when the US government reversed its century-old policy of extermination and—despite some political and cultural opposition—began the reintroduction of forty-one wild wolves from Canada and northwest Montana. In the intervening decades, scientists have studied their myriad behaviors, from predation to mating to wolf pup play, building a one-of-a-kind field study that has both allowed us to witness how the arrival of top predators can change an entire ecosystem and provided a critical window into impacts on prey, pack composition, and much else.
 
Here, for the first time in a single book, is the incredible story of the wolves’ return to Yellowstone National Park as told by the very people responsible for their reintroduction, study, and management. Anchored in what we have learned from Yellowstone, highlighting the unique blend of research techniques that have given us this knowledge, and addressing the major issues that wolves still face today, this book is as wide-ranging and awe-inspiring as the Yellowstone restoration effort itself. We learn about individual wolves, population dynamics, wolf-prey relationships, genetics, disease, management and policy, newly studied behaviors and interactions with other species, and the rippling ecosystem effects wolves have had on Yellowstone’s wild and rare landscape. Perhaps most importantly of all, the book also offers solutions to ongoing controversies and debates.
 
Featuring a foreword by Jane Goodall, beautiful images, a companion online documentary by celebrated filmmaker Bob Landis, and contributions from more than seventy wolf and wildlife conservation luminaries from Yellowstone and around the world, Yellowstone Wolves is a gripping, accessible celebration of the extraordinary Yellowstone Wolf Project—and of the park through which these majestic and important creatures once again roam.
