Agriculture is often considered as one of the main threats to ecosystems. Unsustainable farming practices often result in habitat loss, inefficient use of water, soil degradation, pollution, genetic erosion, among other negative impacts on human life, including hunger, low food quality, reduced access to food resources, as well as the abandonment of rural areas. Nevertheless, when agriculture is practiced in a sustainable way, it can contribute to the preservation of many habitats, to the protection of watersheds, to the preservation and improvement of soil health. The use of sustainable and ecological practices is the key feature distinguishing traditional agriculture from intensive one. It...
Dark Age Liguria surveys the history of the Liguria region from c. 400 to c. 1050 AD, to provide a detailed case study of what happened here as Roman imperial rule ended. The book pulls together all the surviving evidence, written, archaeological, artistic and ecological, to propose that, in contrast with later periods, Ligurians looked north as much as they gazed out to sea. Genoese history under Byzantines, Lombards, Carolingians and Ottonians is compared with that of other coastal settlements, including Albenga, Noli, Perti and Savona and the less-studied but fascinating inland valleys, the Aveto, Polcevera, Stura and Vara. The book draws also on more than fifteen years of fieldwork in and around the small town of Varese Ligure (La Spezia province) to suggest some new methods for investigating the Dark Age past.
The Marakwet of Kenya is a study of a sub-group of the greater Kalenjin community, the majority of whom live in the Rift Valley Province of Kenya. It is an excellent introduction to the study of an African community in transition, both from its belief systems and in its broad structure and organisation. This work is invaluable to any student of comparative studies; whether in sociology, anthropology, economics or history.

In-cell NMR spectroscopy is a relatively new field. Despite its short history, recent in-cell NMR-related publications in major journals indicate that this method is receiving significant general attention. This book provides the first informative work specifically focused on in-cell NMR. It details the historical background of in-cell NMR, host cells for in-cell NMR studies, methods for in-cell biological techniques and NMR spectroscopy, applications, and future perspectives. Researchers in biochemistry, biophysics, molecular biology, cell biology, structural biology as well as NMR analysts interested in biological applications will all find this book valuable reading.
Landscapes are frequently seen as fragments of natural habitat surrounded by a 'sea' of agriculture. But recent ecological theory shows that the nature of these fragments is not nearly as important for conservation as is the nature of the matrix of agriculture that surrounds them. Local extinctions from conservation fragments are inevitable and must be balanced by migrations if massive extinction is to be avoided. High migration rates only occur in what the authors refer to as 'high quality' matrices, which are created by alternative agroecological techniques, as opposed to the industrial monocultural model of agriculture. The authors argue that the only way to promote such high quality matr...
