Book Description
Coffea arabica, one of the economically most important crops worldwide, occurs naturally in the undergrowth of montane rainforests of Ethiopia. The study provides the first detailed ecophysiological investigations of wild coffee populations. It demonstrates the inter- and intra-regional variability in phenotypic and hydrological characteristics of wild coffee. The results reveal very different strategies of wild coffee seedlings for coping with drought stress. The ecophysiological diversity shows the importance of Ethiopian wild coffee populations as gene pools for future breeding programs, and underlines the need for an in-situ conservation strategy. The study includes recommendations for coffee forest management and the use of wild arabica coffee in Ethiopia.

Book Description
"Enchanting . . . An absorbing narrative of politics, ecology, and economics."--New York Times Book Review (Editor's Choice) Located between the Great Rift Valley and the Nile, the cloud forests in southwestern Ethiopia are the original home of Arabica, the most prevalent and superior of the two main species of coffee being cultivated today. Virtually unknown to European explorers, the Kafa region was essentially off-limits to foreigners well into the twentieth century, which allowed the world's original coffee culture to develop in virtual isolation in the forests where the Kafa people continue to forage for wild coffee berries. Deftly blending in the long, fascinating history of our favorite drink, award-winning author Jeff Koehler takes readers from these forest beginnings along the spectacular journey of its spread around the globe. With cafés on virtually every corner of every town in the world, coffee has never been so popular--nor tasted so good. Yet diseases and climate change are battering production in Latin America, where 85 percent of Arabica grows. As the industry tries to safeguard the species' future, breeders are returning to the original coffee forests, which are under threat and swiftly shrinking. "The forests around Kafa are not important just because they are the origin of a drink that means so much to so many," writes Koehler. "They are important because deep in their shady understory lies a key to saving the faltering coffee industry. They hold not just the past but also the future of coffee." "A must-read for coffee enthusiasts."--Smithsonian (Best of the Year) "Reads like an engaging multimystery detective novel."--Wall Street Journal "Fascinating . . . How a local crop transformed into a global commodity."--Real Simple (Best of the Month) Coffee is one of the largest and most valuable commodities in the world. This is the story of its origins, its history, and the threat to its future, by the IACP Award–winning author of Darjeeling.

Book Description
UNESCO Biosphere Reserves (BRs) are designated areas in geographical regions of global socio-ecological significance. This definitive book shows their global relevance and contribution to environmental protection, biocultural diversity and education. Initiated in the 1970s as part of UNESCO’s Man and Biosphere (MAB) Programme, BRs share a set of common objectives, to support and demonstrate a balance between biodiversity conservation, sustainable development and research. The world’s 701 BRs form an international, intergovernmental network to support the aims of sustainability science, but this purpose has not always been widely understood. In three distinct sections, the book starts by outlining the origins of BRs and the MAB Programme, showing how they contribute to advancing sustainable development. The second section documents the evolution of BRs around the world, including case studies from each of the five UNESCO world regions. Each case study demonstrates how conservation, sustainable development and the role of scientific research have been interpreted locally. The book concludes by discussing thematic lessons to help understand the challenges and opportunities associated with sustainability science, providing a unique platform from which lessons can be learned. This includes how concepts become actions on the ground and how ideas can be taken up across sites at differing scales. This book will be of great interest to professionals engaged in conservation and sustainable development, NGOs, policy-makers and advanced students in environmental management, ecology, sustainability science, environmental anthropology and geography.

Book Description
Solanum quitoense (Lulo) from the northern Andes is a fruit with an attractive taste. It has a high export potential but its production is hampered by insufficient pollination. Studies on the reproductive system of Lulo revealed that, due to their poricidal anthers, the flowers need pollinators for self- and cross-pollination. Pollination by native bumblebees significantly increases fruit set and quality. Experiments show that colonies of Bombus atratus can be reared in captivity and used in Lulo fields for providing increased pollination services. Modeling based on data on colony development reveal larva/workers ratio and the supply of pollen as main parameters for improving the rearing method.

Book Description
This book presents advanced knowledge on the relationships between climate change and agriculture, and various adaptation techniques such as low tillage, salt-adapted beneficial microbes and closed systems. Climate change is unavoidable but adaptation is possible. Climate change and agriculture are interrelated processes, both of which take place on a global scale. Climate change affects agriculture through changes in average temperatures, rainfall and climate extremes; changes in pests and diseases; changes in atmospheric carbon dioxide; changes in the nutritional quality of some foods; and changes in sea level.

Book Description
The conservation and sustainable use of biodiversity are issues that have been high on the policy agenda since the first Earth Summit in Rio in 1992. As part of efforts to implement in situ conservation, a methodology referred to as community biodiversity management (CBM) has been developed by those engaged in this arena. CBM contributes to the empowerment of farming communities to manage their biological resources and make informed decisions on the conservation and use of agrobiodiversity. This book is the first to set out a clear overview of CBM as a methodology for meeting socio-environmental changes. CBM is shown to be a key strategy that promotes community resilience, and contributes to the conservation of plant genetic resources. The authors present the underlying concepts and theories of CBM as well as its methodology and practices, and introduce case studies primarily from Brazil, Ethiopia, France, India, and Nepal. Contributors include farmers, leaders of farmers’ organizations, professionals from conservation and development organizations, students and scientists. The book offers inspiration to all those involved in the conservation and use of agrobiodiversity within livelihood development and presents ideas for the implementation of farmers’ rights. The wide collection of experiences illustrates the efforts made by communities throughout the world to cope with change while using diversity and engaging in learning processes. It links these grassroots efforts with debates in policy arenas as a means to respond to the unpredictable changes, such as climate change, that communities face in sustaining their livelihoods.
