Описание:
How are different concepts of nature and time embedded into human practices of landscape and environmental management? And how can temporalities that entwine past, present and future help us deal with challenges on the ground? In a time of uncertainty and climate change, how much can we hold onto ideals of nature rooted in a pristine and stable past? The Scandinavian and Australian perspectives in this book throw fresh light on these questions and explore new possibilities and challenges in uncertain and changing landscapes of the future.
This book presents examples from farmers, gardens and Indigenous communities, among others, and shows that many people and communities are already actively engaging with environmental change and uncertainty. The book is structured around four themes; environmental futures, mobile natures, indigenous and colonial legacies, heritage and management. Part I includes important contributions towards contemporary environmental management debates, yet the chapters in this section also show how the legacy of older landscapes forms part of the active production of future ones. Part II examines the challenges of living with mobile natures, as it is acknowledged that environments, natures and people do not stand still. An important dimension of the heritage and contemporary politics of Australia, Sweden and Norway is the presence of indigenous peoples. As is clear in part III, the legacies of the colonial past both haunt and energise contemporary land management decisions. Finally, part IV demonstrates how the history and heritage of landscapes, including human activities in those landscapes, are entwined with contemporary environmental management.
The rich empirical content of the chapters exposes the diversity of meanings, practices, and ways of being in nature that can be derived from cultural environmental research in different disciplines. The everyday engagements between people, nature and temporalities provide important creative resources with which to meet future challenges.
Описание: Karst is a type of landscape, and also an aquifer type. Karst areas consist of solid but chemically soluble rock such as limestone (most important) and dolomite, but also gypsum, anhydrite and several other soluble rocks. It is characterised by underground drainage systems with sinkholes and caves. It has also been documented for weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered or confined by one or more superimposed non-soluble rock strata, distinctive karst surface developments might be totally missing. Karst aquifers are characterised by a network of conduits and caves formed by chemical dissolution, allowing for rapid and often turbulent water flow. Karst aquifers form by flowing water containing carbon dioxide which dissolves carbonate rocks. Therefore, there is a close relation between aquifer evolution, the formation of caves and groundwater flow. Hundreds of millions of people worldwide live in karst areas and are supplied by drinking water from karst aquifers. These aquifers include valuable freshwater resources, but are sometimes difficult to exploit and are almost always vulnerable to contamination, due to their specific hydrogeologic properties. Therefore, karst aquifers require increased protection and application of specific hydrogeologic methods for their investigation. Other problems frequently encountered in karst areas include: soil erosion and rock desertification, leakages of channels and reservoirs, collapse of underground cavities and formation of sinkholes, and flooding. Resolution of these problems requires involvement of karst hydrogeology experts. This book covers the topics understanding of cave and karst related processes and facilitates the translation of current discipline-specific research to an interdisciplinary readership by dealing with specific cave or karst systems. The book addresses a multi-disciplinary approach involved in anthropology, archaeology, biology, chemistry, geography, geology, geomorphology, hydrogeology, palaeontology, sedimentology, and all other disciplines related to speleology and karst terrains.
