Book Description
High altitude research is comparatively a recent development. With the notable exceptions of entomology, botany and perhaps some aspects of human acclimatization, our knowledge of high altitude environment is extremely scanty. There is at present no comprehensive handbook on the general ecology of highlands. This book aims at providing such a text for the use of the general scientist, engineer, biologist and university students. It summarizes and critically reviews current developments and focusses atten tion on urgent problems of highland ecology needing future studies. This book has grown out of our explorations and experiences in the highlands of Asia and South America. The results of explorations of the high altitude plants and insects on the Himalaya, Alai-Pamirs, Central Tien Shan and Caucasus by one of us (MSM), discussed in earlier publications, are reviewed here in the light of recent advances. Many years' experience of teaching and research in the University of Sucre (3400 m) and studies at Potosi (4000 m), La Paz and Chacaltaya (5000 m) in Bolivia by the second author (LEG) cover problems in physical chemistry, meteorology, engineer ing and other physical aspects of highland environments.

Book Description
Deforestation of Scotland began millennia ago and by the early 20th century woodland cover was down to about 6 per cent of the total land area. A century later woodland cover had tripled. Most of the newly established forestry plantations were created on elevated land with wet peaty soils and high wind exposure, not exactly the condition in which forests naturally thrive. Jan Oosthoek tells in this book the story of how 20th century foresters devised ways to successfully reforest the poor Scottish uplands, land that was regarded as unplantable, to fulfil the mandate they had received from the Government and wider society to create a timber reserve. He raises the question whether the adopted forestry practice was the only viable means to create forests in the Scottish Highlands by examining debates within the forestry community about the appearance of the forests and their longterm ecological prospects. Finally, the book argues that the long held ecological convictions among foresters and pressure from environmentalists came together in the late 20th century to create more environmentally sensitive forestry.

Book Description
There is an urgent need to increase agricultural productivity in sub-Saharan Africa in a sustainable and economically-viable manner. Transforming risk-averse smallholders into business-oriented producers that invest in producing surplus food for sale provides a formidable challenge, both from a technological and socio-political perspective. This book addresses the issue of agricultural intensification in the humid highland areas of Africa – regions with relatively good agricultural potential, but where the scarce land resources are increasingly under pressure from the growing population and from climate change. In addition to introductory and synthesis chapters, the book focuses on four themes: system components required for agricultural intensification; the integration of components at the system level; drivers for adoption of technologies towards intensification; and the dissemination of complex knowledge. It provides case studies of improved crop and soil management for staple crops such as cassava and bananas, as well as examples of how the livelihoods of rural people can be improved. The book provides a valuable resource for researchers, development actors, students and policy makers in agricultural systems and economics and in international development. It highlights and addresses key challenges and opportunities that exist for sustainable agricultural intensification in the humid highlands of sub-Saharan Africa.

Book Description
Think of the Highlands as the “backyard” and “backstop” of the Philadelphia–New York–Hartford metroplex. A backyard that spans over three million acres across Pennsylvania, New York, and Connecticut, the Highlands serves as recreational open space for the metroplex’s burgeoning human population. As backstop, Highlands’ watersheds provide a ready source of high-quality drinking water for over fifteen million people. The Highlands is the first book to examine the natural and cultural landscape of this four-state region, showing how it’s distinctive and why its conservation is vital. Each chapter is written by a different leading researcher and specialist in that field, and introduces readers to another aspect of the Highlands: its geological foundations, its aquifers and watersheds, its forest ecology, its past iron industry. In the 1800s, the Highlands were mined, cutover, and then largely abandoned. Given time, the forests regenerated, the land healed, and the waters cleared. Increasingly, however, the Highlands are under assault again—polluted runoff contaminating lakes and streams, invasive species choking out the local flora and fauna, exurban sprawl blighting the rural landscape, and climate change threatening the integrity of its ecosystems. The Highlands makes a compelling case for land use planning and resource management strategies that could help ensure a sustainable future for the region, strategies that could in turn be applied to other landscapes threatened by urbanization across the country. The Highlands are a valuable resource. And now, so is The Highlands.

Book Description
Lawrence S. Grossman explores the far-reaching implications of the conflicts between subsistence and commodity production in developing countries. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Book Description
Truly high altitude aquatic ecosystems are found primarily at lower latitudes: vast regions in the tropical part of the Andes, the Himalayas and Tibet, considerable areas in East Africa, and minor zones of Oceania. However, despite their abundance in these regions, their biology and ecology has never been summarized in detail. A current synthesis of the topic is therefore timely. High altitude waters are ideal systems with which to address a broad range of key and topical themes in ecology, both at the regional and global scales. From specific functional adaptations of aquatic species to harsh environmental conditions through to global diversity patterns along altitudinal gradients and extinction risks of mountain populations due to vanishing glaciers, ecological patterns and processes found in high altitude waters are both diverse and singular. Although poorly considered in classical textbooks of ecology and limnology, high altitude waters have much to offer existing (aquatic) ecological theories and applications. These often threatened and exploited habitats are also ideal for studying the intimate interactions between social and ecological systems that characterize the majority of ecosystems in the Anthropocene.

Book Description
"Tropical Pioneers documents the conversion of a tropical rainforest biome and the collision between what previously had been more discrete ecological zones within South Asia. The author demonstrates that profound ecological transformations occurred in the highlands of Sri Lanka during the nineteenth century and suggests that the integration of tropical ecological zones is an important theme for historians to investigate elsewhere."--BOOK JACKET.
