Japanese Commons in the Coastal Seas - How the Satoumi Concept Harmonizes Human Activity in Coastal Seas with High Productivity... Japanese Commons in the Coastal Seas - How the Satoumi Concept Harmonizes Human Activity in Coastal Seas with High Productivity and Diversity (Hardcover, 2013 ed.)
Tetsuo Yanagi
R2,770 Discovery Miles 27 700 Ships in 10 - 15 working days

The author proposed the satoumi concept, analogous to the satoyama concept on land, as coastal sea with high biodiversity and productivity in harmony with human interaction in 1998. The concept for environmental conservation in the coastal seas has been widely accepted and was included in the Japanese national policy of Strategy for Establishment of an Environmental Nation in 2007. This book is a translation of the author s Japanese book (2010) in response to concerns and questions about satoumi, including: Does biodiversity increase as a result of human interaction in coastal seas? Do the economics of fishing villages need to be considered in detail? What legal support is necessary for the creation of satoumi? Is there a relation between the concepts of God and Nature in satoumi? What is the relationship between fishermen and city dwellers? Chapter 1 presents the basic concept of satoumi. In Chapter 2 the relation between biodiversity and human interaction, economic problems related to satoumi, legal support for satoumi creation, satoumi" "from the point of view of landscape ecology, and the relation between society and science with regard to the satoumi movement are discussed. In Chapter 3 examples of satoumi creation in Japan are presented, andin Chapter 4 the overseas dissemination of the satoumi concept is introduced, with Chapter 5 providing the conclusion. Chapter 1 presents the basic concept of satoumi.

Veins of the Desert - A Review on Qanat / Falaj / Karez (Hardcover): Ali Asghar Semsar Yazdi, Majid Labbaf Khaneiki Veins of the Desert - A Review on Qanat / Falaj / Karez (Hardcover)

Qanat is a gently sloping subterranean canal, which taps a water-bearing zone at a higher elevation than cultivated lands. A qanat consist of a series of vertical shafts in sloping ground, interconnected at the bottom by a tunnel with a gradient flatter than that of the ground. From the air, this system looks like a line of anthills leading from the foothills across the desert to the greenery of an irrigated settlement. Qanat engages a variety of knowledge and its studying entails an interdisciplinary approach. In a traditional realm, qanats are embraced by a socio-economic system which guarantees their sustainability. The facets of this socio-economic system operate closely together and make it possible for the qanats to remain into future. Veins of the Desert shows that digging a qanat requires a variety of sciences and technologies, though at a glance qanat is just a horizontal tunnel which drains out groundwater. Qanat is a feat of technology left from our ancestors; hidden underground, but its technical importance is apparent, not less valuable than such surface structures as bridges, castles, towers, etc. Qanat enjoys extended structures and sometimes its length reaches tens of kilometers. It passes through geological formations and faces different conditions and obstacles, so the qanat masters' efforts to solve these problems led to the accumulation of knowledge in terms of qanat construction over time, which has been handed down from generation to generation. Qanat is one of the most complicated traditional technologies, which require knowledge on nature ranging from groundwater to management. This indigenous technology used to bring water efficiently from tens of kilometers away to the thirsty lands. This book also gives insight into cultural and social heritages, which have crystalized around this technique. This cultural heritage still influences social life of the people living in such regions as central plateau of Iran where qanat has been the only means of supplying water. This technology is the focal point of the genesis of a particular civilization in the arid and semi-arid regions of Iran. The harsh environment drove those people to invent the technology of qanat and the know-how revolving around it. Qanat carries a tradition of science and technology which used to be practiced in order to overcome the technical obstacles in qanat construction. Thus, qanat is not only an irrigational means, but it should be seen as a technical and cultural legacy which deserves more attention. This book is a small encyclopedia on qanat system, providing the readers with easy answers to their questions about different aspects of this ancient technology.

Mountaineering in the Swiss Alps presents a selection of classic routes in the main Swiss climbing areas that have forged Switzerland's reputation as a mountaineering paradise. Featured are over thirty climbs, ranging from relatively easy normal routes to more challenging itineraries. All are within the capabilities of most mountaineers and provide an excellent introduction to the wide variety of climbing that Switzerland has to offer. Every route, whether it is a pure rock climb, a mixed ridge, a big north face or a long traverse, was chosen for the beauty of the surroundings and the quality of the climbing. Some are on world famous peaks that every mountaineer aspires to climb, such as the Matterhorn (Mont Cervin), the Breithorn and the Monch; others are on lesser-known summits and will delight those who like getting away from the beaten track. Written by mountaineer and author Stephane Maire, each route features technical notes, a route description and topo, and photos illustrating the climb's unique character.

R1,846 Discovery Miles 18 460 Ships in 12 - 17 working days

Much of the convenience of modern life resides in sheet metal, the cowling shield of most machines and appliances. However, the load that this takes off human shoulders has to be carried elsewhere, and the Earth has borne the burden. Many of us woke up to the environmental cost when over a century of industrialization finally surpassed the capacity of nature to assimilate it. International in scope, Heavy Metals in the Environment: Using Wetlands for Their Removal discusses wetland functions and heavy metal contamination. It addresses such questions as: Can systems powered by sunlight handle toxins more effectively than systems running on fossil fuel? At what scale and by what means do we define efficiency? These questions resonate increasingly with a number of global challenges. As inescapable as climate change, you can no longer avoid airborne toxins, acid rain, and polluted water by moving away from them. When the time comes to rely less on fossil fuel-based technology, how will we clean up the aftermath of toxic misadventures? Written by a leader in the growing field of ecological engineering, Heavy Metals in the Environment: Using Wetlands for Their Removal presents scientific studies that illustrate how natural systems use wetlands to adapt to changes in the ecosystem. It focuses primarily on lead, one of the first materials used by developing civilizations and a metal used heavily in the industrial era. The goal: to achieve a better understanding of how natural systems use wetlands to adapt to wastes.

Climate Hazard Crises in Asian Societies and Environments (Paperback): Troy Sternberg Climate Hazard Crises in Asian Societies and Environments (Paperback)
Troy Sternberg
R907 Discovery Miles 9 070 Ships in 12 - 17 working days

Climate hazards are the world's most widespread, deadliest and costliest natural disasters. Knowledge of climate hazard dynamics is critical since the impacts of climate change, population growth, development projects and migration affect both the impact and severity of disasters. Current global events highlight how hazards can lead to significant financial losses, increased mortality rates and political instability. This book examines climate hazard crises in contemporary Asia, identifying how hazards from the Middle East through South and Central Asia and China have the power to reshape our globalised world. In an era of changing climates, knowledge of hazard dynamics is essential to mitigating disasters and strengthening livelihoods and societies across Asia. By integrating human exposure to climate factors and disaster episodes, the book explores the environmental forces that drive disasters and their social implications. Focusing on a range of Asian countries, landscapes and themes, the chapters address several scales (province, national, regional), different hazards (drought, flood, temperature, storms, dust), environments (desert, temperate, mountain, coastal) and issues (vulnerability, development, management, politics) to present a diverse, comprehensive evaluation of climate hazards in Asia. This book offers an understanding of the challenges climate hazards present, their critical nature and the effort needed to mitigate climate hazards in 21st-century Asia. Climate Hazard Crises in Asian Societies and Environments is vital reading for those interested and engaged in Asia's development and well-being today and will be of interest to those working in Geography, Development Studies, Environmental Sciences, Sociology and Political Science.

Human and Environmental Security in the Era of Global Risks - Perspectives from Africa, Asia and the Pacific Islands... Human and Environmental Security in the Era of Global Risks - Perspectives from Africa, Asia and the Pacific Islands (Hardcover, 1st ed. 2019)
Mohamed Behnassi, Himangana Gupta, Olaf Pollmann
R3,964 Discovery Miles 39 640 Ships in 12 - 17 working days

This book discusses ways to deepen the debate on the linkages between global risks and human and environmental security. The approach put forward in this book is one of questioning the ability of existing concepts, regulatory frameworks, technologies and decision-making mechanisms to accurately deal with emerging risks to human and environmental security, and to act in the direction of effectively managing their impacts and fostering the resilience of concerned systems and resources. Empirical research findings from Africa, Asia and the Pacific Islands are provided. During the last decades the links between emerging risks and the security of humans and nature have been the object of considerable research and deliberations. However, it is only recently becoming an important focus of policy making and advocacy. In this contributed volume, it is presumed that the ability - or lack thereof - to make innovative conceptual frameworks, institutional and policy arrangements, and technological advances for managing the current emerging risks, will foster or undermine the environmental security, and consequently determine the future human security. Moreover, taking into account the links between environmental/climate security, human security and sustainability will help frame a new research agenda and potentially develop a broad range of responses to many delicate questions.

The Little Ice Age - Ancient and Modern (Paperback, 2nd edition): The Little Ice Age - Ancient and Modern (Paperback, 2nd edition)
R1,297 Discovery Miles 12 970 Ships in 12 - 17 working days

The evidence for the Little Ice Age, the most important fluctuation in global climate in historical times, is most dramatically represented by the advance of mountain glaciers in the sixteenth and seventeenth centuries and their retreat since about 1850. The effects on the landscape and the daily life of people have been particularly apparent in Norway and the Alps. This major book places an extensive body of material relating to Europe, in the form of documentary evidence of the history of the glaciers, their portrayal in paintings and maps, and measurements made by scientists and others, within a global perspective. It shows that the glacial history of mountain regions all over the world displays a similar pattern of climatic events. Furthermore, fluctuations on a comparable scale have occurred at intervals of a millennium or two throughout the last ten thousand years since the ice caps of North America and northwest Europe melted away. This is the first scholarly work devoted to the Little Ice Age, by an author whose research experience of the subject has been extensive. This book includes large numbers of maps, diagrams and photographs, many not published elsewhere, and very full bibliographies. It is a definitive work on the subject, and an excellent focus for the work of economic and social historians as well as glaciologists, climatologists, geographers, and specialists in mountain environment.

R1,313 Discovery Miles 13 130 Ships in 12 - 17 working days

Through stories of diverse landscapes from around the world, this book captures human cultures and their land use practices in the environments they inhabit. The chapters cover topics from heritage in the 21st Century, appreciating and safeguarding values while facing challenges wrought by change. This title will lead readers through fascinating stories of landscapes and people. We learn of the physical and spiritual structure of rice terraces of the Honghe Mountains in China maintained by following a 1300 year sustainable practice of water allocation, while the colonial tea plantations of the Sri Lankan highlands are managed by Indian Tamils who now seek tourism as a means of additional income. Sustainable agricultural methods in the USA are being introduced to prevent landscape loss while in Australia a challenge confronting family farms is progressing to rural industrialisation. Challenges are further outlined in the mythical story of Finland's Saint Henrik pilgrimage and in the intangible Ui-won gardens of Korea. The huge challenge for Japan's landscapes is the legacy from fierce natural 21st Century disasters while in Australia's Dampier Archipelago, an avoidable yet brutal development on a unique Aboriginal rock sculptured landscape highlights serious concerns about heritage governance. These remarkable stories of landscapes and their management are inseparable from the communities that inhabit them. This book was originally published as a special issue of Landscape Research.

R1,328 Discovery Miles 13 280 Ships in 12 - 17 working days

The Mekong Basin in Southeast Asia is one of the largest international river basins in the world. Its abundant natural resources are shared by six riparian countries and provide the basis for the livelihoods of more than 75 million people. However, ongoing socio-economic growth and related anthropogenic interventions impact the region's ecosystems, and there is an urgent need for the monitoring of the basin's land surface dynamics. Remote sensing has evolved as a key tool for this task, allowing for up-to-date analyses and regular monitoring of environmental dynamics beyond physical or political boundaries and at various temporal and spatial scales. This book serves as a forum for remote-sensing scientists with an interest in the Mekong River Basin to present their recent basin-related works as well as applied case studies of the region. A broad range of sensors from high to medium resolution, and from multispectral to SAR systems, are applied, covering topics such as land cover/land use classification and comparison, time series analyses of climate variables, vegetation structure and vegetation productivity, as well as studies on flood mapping or water turbidity monitoring. This book was originally published as a special issue of the International Journal of Remote Sensing.

No matter where they are located in the world, communities living in mountain regions have shared experiences defined in large part by contradictions. These communities often face social and economic marginalization despite providing the lumber, coal, minerals, tea, and tobacco that have fueled the growth of nations for centuries. They are perceived as remote and socially inferior backwaters on one hand while simultaneously seen as culturally rich and spiritually sacred spaces on the other. These contradictions become even more fraught as environmental changes and political strains place added pressure on these mountain communities. Shifting national borders and changes to watersheds, forests, and natural resources play an increasingly important role as nations respond to the needs of a global economy. The works in this volume consider multiple nations, languages, generations, and religions in their exploration of upland communities' responses to the unique challenges and opportunities they share. From paintings to digital mapping, environmental studies to poetry, land reclamation efforts to song lyrics, the collection provides a truly interdisciplinary and global study. The editors and authors offer a cross-cultural exploration of the many strategies that mountain communities are employing to face the concerns of the future.

Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.

R870 Discovery Miles 8 700 Ships in 12 - 17 working days

An expert on the buffalo tells the history of this keystone species through extensive research and beautiful photographs. The mere mention of the buffalo instantly brings to mind the vast herds that once roamed the North American continent, and few wild animals captivate our imaginations as much as the buffalo do. Once numbering in the tens of millions, these magnificent creatures played a significant role in structuring the varied ecosystems they occupied. For at least 24,000 years, North American Indigenous Peoples depended upon them, and it was the abundance of buffalo that initially facilitated the dispersal of humankind across the continent. With the arrival of Europeans and their rapacious capacity for wildlife destruction, the buffalo was all but exterminated. In a span of just thirty years during the mid-1800s, buffalo populations plummeted from more than 30 million to just twenty-three. And with them went all of the intricate food webs, the trophic cascades, and the inter-species relationships that had evolved over thousands of years. Despite this brush with extinction, the buffalo survived, and isolated populations are slowly recovering. As this recovery proceeds, the relationships the animals once had with thousands of species are being re-established in a remarkable process of ecological healing. The intricacy of those restored relationships is the subject of this book. Based on author Wes Olson's thirty-five years of working intimately with bison-and featuring 180 stunning, full-colour photographs by Johane Janelle- The Ecological Buffalo is a story that takes the reader on a journey to understand the myriad connections this keystone species has with the Great Plains.
