This book presents contributions devoted to the hydrogeochemical characterization of aquatic environments of Patagonia, including those of Ushuaia city, known as "The southernmost city in the world". Patagonia (between 39° and 55° S) is located in southern South America. Eight main river systems pour their waters into the SW Atlantic Ocean. Rivers, with their headwaters mainly located in the Andes, supply dissolved and particulate matter to the coastal zone, as well as nutrients, which benefit biological communities. Besides, freshwater in this region with little anthropogenic impact supports human life and a high wildlife biodiversity. Unfortunately, the recent increase in human activities, such as the use of fertilizers, wastewater discharges, extensive deforestation and dam construction, is affecting the quality and quantity of water resources. The book is of interest for researchers, professors and government agencies that decide on water resources management policies.
The Freshwaters of Patagonia adopts a socioecological approach, in which experts from across Patagonia review recent, scientifically rigorous literature and data of their own, thus synthesizing the current knowledge directly relevant to understand the present state and future trends of icefields, freshwater and wetland ecosystems in this region. The book’s organization into three parts provides a studied and comprehensive view on the patterns and processes of the various ecosystems in Patagonia, and describes the sociological aspects of freshwater ecosystems, as well as characterizes the conservation of the freshwater and wetland ecosystems, in Patagonia. The chapters offer a broad, state-of-the-art overview of the current status of glaciers, freshwater and wetland ecosystems of this region, as well as studies of both local and large scale biodiversity patterns, and study cases of extreme and naturally polluted environments.The volume concludes with the current status of Patagonian freshwaters, and discusses the scientific, legal and administrative tools aimed at their sustainable management within the framework of the UNEP Sustainable Development Goals 2030 Agenda. A broad audience of students, scientists, engineers, environmental managers, and policy makers will be interested in this volume.
This book aims to quantify and discuss how societies have directly and indirectly benefited from ecosystem services in Patagonia; not only in terms of provisioning and cultural services, but also regulating and supporting services. Patagonia, a region that stretches across two countries (ca. 10% in Chile and 90% in Argentina), is home to some of the most extensive wilderness areas on our planet. Natural grasslands comprise almost 30% of the Americas, including the Patagonian steppe, while Patagonian southern temperate forests are important for carbon sequestration and storage, play a pivotal role in water regulation, and have become widely recognized for their ecotourism value. However, profound changes are now underway that could affect key ecosystem functions and ultimately human well-being. In this context, one major challenge we face in Patagonia is that ecosystem services are often ignored in economic markets, government policies and land management practices. The book explores the synergies and trade-offs between conservation and economic development as natural landscapes and seascapes continue to degrade in Patagonia. Historically, economic markets have largely focused on the provisioning services (forest products, livestock) while neglecting the interdependent roles of regulating services (erosion and climate control), supporting services (nutrient cycling) and cultural services (recreation, local identity, tourism). Therefore, the present work focuses on ecosystem functions and ecosystem services, as well as on trends in biodiversity and the interactions between natural environments and land-use activities throughout Patagonia.
Geosciences, Environment and Man has three major objectives, which determine the division in three parts of this volume: I. To consider the main natural geological processes interfering with and therefore threatening the activities of man: earthquakes, volcanic eruptions, land movements, floods, wind and coastal risks; main prevention and mitigation measures against these natural hazards are presented. II. To examine the exploitation of earth's natural resources such as materials, ores and minerals, fossil fuels, water, radioactivity, and the resulting consequences on solid Earth balance and future. III. To assess the hold level reached by the activities of man on planet surface envelopes through agriculture, urbanization, industrialization, and communication; the local to global effects of human influence triggered by recent demographic growth on underground, soils, water and air characters are taken into account. Both deteriorating and beneficial aspects of Earth - the interactions of man are emphasized, as well as mitigation or restoration measures and perspectives.
This study presents for the first time an independent and authoritative analysis of water quality management in North and South America, and discusses the practices and future implications of the impacts of the current practices in the different countries of the hemisphere. Includes in-depth case studies analyzing water quality management practices at country and state levels, especially in terms of their effectiveness and overall impact.
Water is newsworthy: there is, or will be, a world water crisis. Aggravated by climate change, we are approaching the limits of human exploitation of freshwater resources, notably in growing essential food. The complexities and uncertainties associated with improving our management of fresh water take the potential remedies out of the hands of simple, local, hard engineering and into much larger units – the basin, the ecosystem and the global context, and also require longer term perspectives. The Third Edition follows the same structure as its predecessors, presenting the historical and scientific backgrounds to land-water interactions and establishing the links with development processes and policies. Throughout, its two major messages are that our new philosophy should be one of ‘humans in the ecosystem’ and that the guidance from science, being uncertain and contested, must be operationalized in a participatory system of governance based on participation. Following a review of progress towards these elements in the developed world, the international case studies update the situation in the developing world following the Millennium Development Goals, our new emphasis on poverty and on global food supplies. This book covers the multitude of scientific research findings, development of ‘tools’ and spatial/temporal scale challenges which have emerged in the last decade. Tensions are highlighted in the current and future role of large dams, country studies are retained (and considerably updated) and development contexts are explored in greater depth as a dividing line in capacity to cope with land and water stress. "Technical issues" have been expanded to cover major droughts, environmental flows and the restoration of rivers and wetlands. A separate chapter picks up these themes under terms of their relationship with uncertainty and the widespread perception that a new ethos of adaptive management is needed in the water sector. For students of geography, environmental science, hydrology, and development studies this innovative edition provides a reasoned, academic basis of evidence for sustainable, adaptive management of rivers and related large-scale ecosystems using more than 600 new sources. It will also prove invaluable for lecturers and practitioners.
Through case studies, opposing viewpoints, and primary documents, this reference work examines the environmental and sustainability issues regarding water as well as how water is an intrinsic part of human culture. Every culture and ecosystem on earth depends on water. As the world's climate changes, human culture is increasingly threatened by the seemingly opposite problems of having too little clean, potable water and "having too much water"—e.g., flooding, melting polar ice caps, and rising sea levels. What are the solutions that humanity must collectively pursue to protect our ability to flourish on planet earth? Water Planet: The Culture, Politics, Economics, and Sustainability of Water on Earth offers an unprecedented examination of the critical subject of water sustainability. Its essays, viewpoints, case studies, and documents show how this vital resource that many in first-world countries take for granted is intricately woven into not only basic human survival but also cultural, political, and economic stability. Readers will learn about topics such as flooding and drought; the growing problem of water pollution; the connections between water and gender, including gender equity and gender aspects of water ownership; the effects of global temperature changes on the water supply; concerns regarding fishing and overfishing; water security; and sustainable water management.
Chilean Patagonia, located at the southwestern tip of South America, is one of the last regions on earth where highly intact environments predominate. With a coastline that extends along some 100,000 km of fjords, channels, and islands, it has one of the world ́s most extensive marine-terrestrial interfaces. Local place-based and Indigenous cultures and management practices are a vital presence across the region, while the long and rich history of conservation efforts have resulted in officially protected areas covering over 50% of the land and 41% of the coastal-marine area. However, Chilean Patagonia is increasingly facing anthropogenic pressures associated with increased infrastructure and access, salmon aquaculture, extractive industries, and the spread of invasive exotic species. Despite widespread recognition that Chilean Patagonia represents a unique global reservoir of socio-natural heritage, to date there has been no region-wide assessment of the scientific evidence of the conservation status of its ecosystems or the priorities for their effective conservation. Conservation in Chilean Patagonia: Assessing the state of knowledge, opportunities, and challenges is the first book to gather and synthesize the available scientific and socio-environmental information related to Patagonian conservation. It presents the collaborative work of 68 researchers and local experts, representing a range of specialties and perspectives, including: biology, ecology, socio-ecology, fisheries, aquaculture, anthropology, economics, geography, tourism, cryosphere, oceanography, climate and global change. The book’s 18 chapters focus on the status of key ecosystems and conservation tools, and provide recommendations toward the construction of a renewed, inclusive, and integrated conservation agenda for the Chilean Patagonian region. It provides an essential primer for anyone interested in the future of this ecologically vital region, as well as lessons on interdisciplinary collaboration and integrated analysis of conservation issues useful for conservation practitioners and scholars. This is an open access book. This book is a translation of an original Spanish edition. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation.
As they provide a negotiating space for a diversity of interests, Multi-Stakeholder Platforms (MSPs) are an increasingly popular mode of involving civil society in resource management decisions. This book focuses on water management to take a positive, if critical, look at this phenomenon. Illustrated by a wide geographical range of case studies from both developed and developing worlds, it recognizes that MSPs will neither automatically break down divides nor bring actors to the table on an equal footing, and argues that MSPs may in some cases do more harm than good. The volume then examines how MSPs can make a difference and how they might successfully co-opt the public, private and civil-society sectors. The book highlights the particular difficulties of MSPs when dealing with integrated water management programmes, explaining how MSPs are most successful at a less complex and more local level. It finally questions whether MSPs are - or can be - sustainable, and puts forward suggestions for improving their durability.
